So you want to create your own computer games
-
-
-Playing computer games is fun. But it is actually more fun to design your own computer
-games and let other people play them. In the past, creating computer games was not easy.
-Commercial computer games you buy nowadays typically take one or two years of
-development with teams of anywhere between 10 and 50 people. Budgets easily reach
-millions of dollars. And all these people are highly experienced: programmers,
-art designers, sound technicians, etc.
-
-
-
-But Game Maker has changed this. With Game Maker you can
-create your own computer games quickly without the need to learn a
-programming language.
-Of course you should not expect to create your
-own Halo 4 or Virtua Tennis within a few weeks. But that is
-also not necessary. The joy of playing a game is not related to its complexity.
-Simpler games, like Tetris, Bejeweled,
-Space Invaders, etc. are a lot of fun to play and a lot easier to create.
-
-
-
-Game Maker offers an intuitive and easy to use drag-and-drop interface
-that allows you to create
-your own games very quickly. You can import and create images, sprites
-(animated images) and sounds and use them. Game Maker is bundled with
-a considerable collection of such resources to get you started.
-You can easily define the objects
-in your game and indicate their behavior, and you can define appealing
-rooms (levels) in which the game takes place. And if
-you want full control there is actually an easy-to-use programming language
-built into Game Maker that gives you full control over what is happening in your game.
-
-
-
-Game Maker focuses on two-dimensional games. So it is not
-meant to create 3D worlds like Quake, even though there is some
-limited functionality for 3D graphics.
-But don’t let this put you down. Many great games use two-dimensional
-sprite technology, even though they look very 3-dimensional. And designing
-two-dimensional games is a lot easier and faster.
-
-
-
-Game Maker comes in two editions, the Lite Edition and the Pro Edition.
-The Lite Edition can be used free of charge but it is limited in its functionality
-and will display popup messages. You can though freely distribute
-the games you create with it; you can even sell them if you like.
-See the enclosed license agreement for more details.
-You are strongly encouraged to upgrade your copy of Game Maker to the Pro Edition.
-It will considerably extend the functionality of Game Maker
-and it will remove the logo when running games.
-This will also support the further development of Game Maker.
-For more information on upgrading see the Pro Edition page.
-
-
-
-This help file will tell you the most important things you need to know about Game Maker
-and how you can create your own games with it. Please realize that,
-even with a program like Game Maker, designing computer games
-is not completely effortless. There are too many aspects that are important:
-game play, graphics, sounds, user interaction, etc. Start with easy
-examples and you will realize that creating games is great fun.
-Also check the web site
-
-for lots of examples, tutorials, ideas, and links to other sites and forums.
-And soon you will become a master game maker yourself. Enjoy.

Installation
-
-
-You probably already did this but if not, here is how to install Game Maker.
-Simply run the program gmaker80.exe. Follow the on-screen instructions.
-You can install the program anywhere you like but it is best to follow the default
-suggestions given. Once installation is completed, in the Start menu you will
-find a new program group where you can start Game Maker
-and read the help file.
-
-
-
-Game Maker also installs a considerable number of images, sprites (animated images)
-and sound effects on your computer, which can be used free of charge in your games. Also
-some example games are installed. All these can be found in folders within the
-location where you installed Game Maker.
-
-
-
-The first time you run Game Maker you are asked whether you
-want to run the program in Simple or Advanced mode.
-If you have not used a game creation program before and you are not an
-experienced programmer, you had better use simple mode (so select No).
-In simple mode fewer options are shown. You can easily switch to
-advanced mode later using the appropriate item in the File menu.
-
-
-
-You will also be shown a tutorial at the right of the window. The tutorial
-will teach you how to quickly create your first game. It will guide you through
-the basic steps in using Game Maker. If you have not used Game Maker
-before you are strongly advised to work your way through the tutorial. You can
-always try the tutorial later through the Help menu.
-
-
-
Requirements
-
-
-Any computer that is less than five years old should be able to run Game Maker without any problems.
-
-
-
-To be more precise, Game Maker requires a resonably modern PC running Windows 2000, XP, Vista, 7, or later.
-A DirectX 8 (or later) compatible graphics card with at least 32MB of memory is required for most created games.
-It requires a screen resolution of at least 800x600 and 65000 (16-bit) colors (preferably full color).
-Also a DirectX 8 compatible sound card is required. Make sure you have the most recent drivers installed.
-Game Maker requires DirectX version 8.0 or later to be installed on your computer.
-(You can download the newest version of DirectX from the Microsoft website at:
-http://www.microsoft.com/windows/directx/.)
-When designing and testing games, the memory requirements are pretty high
-(at least 128 MB and preferably more, also depending on the operating system). When just running games, the memory
-requirements are less severe and depend a lot on the type of game.

Upgrading to the Pro Edition
-
-Game Maker comes in two editions, the Lite Edition and the Pro Edition.
-
-
-The Lite Edition is meant for those that take their first steps on the
-path of developing games. It can be used for free but is limited in its
-functionality. Also it shows a popup logo when running games and will regularly
-remind you of upgrading the program. When you are using Game Maker regularly
-you are strongly recommended to upgrade it to the Pro Edition.
-
-
-The Pro Edition contains considerably more functionality and does not display any
-logos or popup messages. More precisely, the Pro Edition has the following
-additional functionality:
-
-
-
No Game Maker logo is shown when running a game.
-
No regular popups remind you of upgrading.
-
You can use rotated, color blended and translucent sprites.
-
There are additional options in the sprite and image editors.
-
There are additional actions for e.g. CD music, rotated text, and colorized shapes.
-
You can use special sound effects and positional sound.
-
You can create splash screens with movies, images, webpages, texts, etc.
-
There is a particle system to create explosions, fireworks, flames, rain, and other effects.
-
A number of advanced drawing functions are available, for example colorized text and textured polygons.
-
It is possible to create 3D games using functions for 3D graphics.
-
It is possible to create multiplayer games that can be played over a network.
-
You can define your own room transitions.
-
You can use functions to create, load, and modify resources (sprites, backgrounds, etc.)
- while the game is running.
-
There is a collection of functions to create and use data structures.
-
There are functions for motion planning.
-
You get the possibility to include additional files in the game executables
- that can be used when the game is run.
-
The Pro Edition can easily be extended using extension package. These can be made by
- everybody and will in general be provided free of charge.
-
Three such extension packages are included adding many room transitions, windows
- dialogs, and printing facilities.
-
You can define your own trigger events.
-
You can export and import resources, which makes it easier to collaborate on games.
-
-
-
-
-Upgrading the Lite Edition to the Pro Edition costs only 20 Euro or US $25
-(subject to change). This is a one-time fee that will at least be valid
-for all versions 8.x of Game Maker.
-
-
-
-When you are running the Lite Edition, whenever you start Game Maker the following
-form will be shown:
-
-
-
-
-

-You will be brought to a webpage where you can make you payment either by credit card or through PayPal.
-The payment will be handled by the company SoftWrap that is our authorized payment processor.
-Once you made the payment the software will immediately be upgraded to the Pro Edition without
-any further action from your side. Carefully save (and print) the confirmation you receive
-as it contains your purchase reference that you might need later if you want to reinstall the software.
-(When you are running the program, you can also upgrade online by choosing Upgrade to Pro Edition
-in the Help menu.)
-
-
-
-If you purchased Game Maker before (and hence, have an activation code or a previous purchase reference)
-press the button Enter Activation Code. You will be brought to a webpage where you can either enter
-your activation code or your purchase reference from your previous payment. Here you can also retrieve your
-license if you lost it. After you filled in the correct information Game Maker will be upgraded to
-the Pro Edition. Note that you must have an Internet connection for activation.
-(When you are running the program, you can also upgrade on line by choosing Enter Activation Code
-in the Help menu.)
-
-

Getting started
-
-
-Creating your first game is always a challenge. But if you are willing to
-put a little bit of effort in it, it will actually be rather easy. You can
-have it running within an hour.
-
-
-
-Even though it is really easy to make games with Game Maker you will
-need to understand some of the basic concepts. To this end you are strongly
-recommended to follow the tutorial that is shown when Game Maker is started.
-If you did remove the tutorial from view, you can always make it visible again
-by choosing Tutorial in the Help menu.
-
-
-
The Global idea
-
-Before delving into the possibilities of Game Maker it is good to
-get a feeling for the global idea behind the program. Games created
-with Game Maker take place in one or more rooms. (Rooms are
-flat, not 3D, but they can contain 3D-looking graphics.) In these rooms
-you place objects, which you can define in the program. Typical
-objects are the walls, moving balls, the main character, monsters, etc.
-Some objects, like walls, just sit there and don’t do anything. Other
-objects, like the main character, will move around and react to input
-from the player (keyboard, mouse, and joystick) and to each other. For
-example, when the main character meets a monster he might die. Objects
-are the most important ingredients of games made with Game Maker,
-so let us talk a bit more about them.
-
-
-
-First of all, most objects need some image to make them visible on the
-screen. Such images are called sprites. A sprite is often not a
-single image but a set of images that are shown one after the other to
-create an animation. In this way it looks like the character walks, a
-ball rotates, a spaceship explodes, etc. During the game, the sprite for a
-particular object can change. (So the character can look different when
-it walks to the left or to the right.) You can create you own sprites in
-Game Maker or load them from files (e.g. PNG files or animated GIF’s).
-Many sprites come bundled with Game Maker that you can use free
-of charge in your games.
-
-
-
-Certain things will happen to objects. Such happenings are called
-events. Objects can take certain actions when events happen.
-There are a large number of different events that can take place and a
-large number of different actions that you can let your objects take. For
-example, there is a creation event when the object gets created.
-(To be more precise, when an instance of an object gets created; there
-can be multiple instances of the same object.) For example, when a ball
-object gets created you can give it some motion action so that it
-starts moving. When two objects meet, you get a collision event. In
-such a case you can make the ball stop or reverse direction. You can also
-play a sound effect. To this end Game Maker lets you define
-sounds. When the player presses a key on the keyboard there is a
-keyboard event, and the object can take an appropriate action, like
-moving in the direction indicated. We hope you get the idea. For each
-object you design, you can indicate actions for various events; in this
-way defining the behavior of the object.
-
-
-
-Once you have defined your objects it is time to define the rooms
-in which they will live. Rooms can be used for levels in your game or to
-check out different places. There are actions to move from one room to
-another. Rooms, first of all, have a background. This can be a
-simple color or an image. Such background images can be created in
-Game Maker or you can load them from files. (The background can do a
-lot of things but for the time being, just consider it as something that
-makes the rooms look nice.) Next, you can place the objects in the room.
-You can place multiple instances of the same object in a room. So, for
-example, you need to define just one wall object and can use it at many
-places. Also you can have multiple instances of the same monster objects,
-as long as they have the same behavior.
-
-
-
-Now you are ready to run the game. The first room will be shown and
-objects will come to life because of the actions in their creation
-events. They will start reacting to each other due to actions in
-collision events and they can react to the player using the actions in
-keyboard or mouse events.
-
-
-
-So in summary, the following things (often called resources) play a
-crucial role:
-
-
-
-
objects: which are the true entities in the game
-
rooms: the places (levels) in which the objects live
-
sprites: (animated) images that are used to represent the objects
-
sounds: these can be used in games, either as background music or as effects
-
backgrounds: the images used as background for the rooms
-
-
-
-There are actually a number of other types of resources: paths, scripts,
-fonts, and time lines. These are only important for more complicated
-games. You will only see them when you run Game Maker in advanced
-mode. They will be treated in the advanced chapters later in this
-document.

The global user interface
-
-When you start Game Maker the following form is shown. Note that the
-form might in reality also show some Game Maker news and the tutorial
-might be visible at the right side.
-
-
-
-
-
-(Actually, this is what you see when you run Game Maker in simple
-mode. In advanced mode a number of additional items are shown.) At the
-left, you see the different resources mentioned above: Sprites, Sounds,
-Backgrounds, Objects, Rooms and two more: Game Information and Global Game
-Settings. At the top there is the familiar menu and toolbar. In this
-chapter we will describe briefly the various menu items, buttons, etc. In
-the later chapters we discuss a number of them in detail. Note that many
-things can be achieved in different ways: by choosing a command from the
-menu, by clicking a button, or by right clicking on a resource.
-
-
-
-
File menu
-
-In the file menu you can find some of the usual commands to load and save
-files, plus a few special ones:
-
-
-
New. Choose this command to start creating a new game. If
- the current game was changed you are asked whether you want to save it.
- There is also a toolbar button for this.
-
Open. Opens a game file. Game Maker files have the
- extension .gmk. You can also open old .gm6 files. (If you want to open .gmd files
- created with version 5 of Game Maker you must select the appropriate
- file type at the bottom of the dialog. These might though not
- work correctly in the new version.) There is a toolbar button for this command. You can also
- open a game by dragging the file into the Game Maker window.
-
Recent Files. Use this submenu to reopen game files you
- recently opened.
-
Save. Saves the game design file under its current name. If
- no name was specified before, you are asked for a new name. You can only
- use this command when the file was changed. Again, there is a toolbar
- button for this.
-
Save As. Saves the game design file under a different name.
- You are asked for a new name.
-
Create Executable. Once your game is ready you will probably want
- to give it to others to play. Using this command you can create a stand-
- alone version of your game. This is simply an executable that you can
- give to other people to run.
-
Advanced Mode. When clicking on this command Game Maker
- will switch between simple and advanced mode. In advanced mode
- additional commands and resources are available.
-
Exit. Probably obvious. Press this to exit Game Maker
- . If you changed the current game you will be asked whether you want
- to save it.
-
-
-
-
Edit menu
-
-The edit menu contains a number of commands that relate to the currently
-selected resource (object, sprite, sound, etc.). Depending on the type of
-resource some of the commands may not be visible.
-
-
-
Insert resource. Inserts a new instance of the currently
- selected type of resource before the current one. A form will open in
- which you can change the properties of the resource. This will be treated
- in detail in the following chapters.
-
Duplicate. Makes a copy of the current resource and adds it.
- A form is opened in which you can change the resource.
-
Delete. Deletes the currently selected resource (or group of
- resources). Be careful. This cannot be undone. You will, though, be warned.
-
Rename. Gives the resource a new name. This can also be done
- in the property form for the resource. Also, you can select the resource
- and then click on the name.
-
Properties. Use this command to bring up the form to edit
- the properties. Note that all the property forms appear within the main
- form. You can edit many of them at the same time. You can also edit the
- properties by double clicking on the resource.
-
-
-Note that all these commands can also be given in a different way. Right-
-click on a resource or resource group, and the appropriate pop-up menu
-will appear.
-
-
-
Resources menu
-
-In this menu, you can create new resources of each of the different types.
-Note that for each of them there is also a button on the toolbar and a
-keyboard shortcut. Also you can change the game information and the global
-game settings.
-
-
-
Run menu
-
-This menu is used to run the game. There are two ways to run a game.
-
-
-
Run normally. Runs the game as it would normally run.
- The game is run in the most efficient way and will look and act as in an executable game.
-
Run in Debug mode. Runs the game in debug mode. In this mode
- you can check certain aspects of the game and you can pause and step
- through it. This is useful when something goes wrong but is a bit
- advanced.
-
-
-Once your game is finished, you can create a stand-alone executable of
-the game using the command in the file menu.
-
-
-
Window menu
-
-In this menu you find some of the usual commands to manage the different
-property windows in the main form:
-
-
-
Cascade. Cascade all the windows such that each of them is
- partially visible.
-
Arrange Icons. Arrange all the iconified property windows.
- (Useful in particular when resizing the main form.)
-
Close All. Close all the property windows, asking the user
- whether or not to save the changes made.
-
-
-
-
Help menu
-
-Here you find some commands to help you:
-
-
-
Contents. Use this command to show this help file.
-
Tutorials. Use this submenu to show the different tutorials that are provided with Game Maker
- to teach you how to make your first games.
-
Upgrade to Pro Edition. You can use this command to upgrade the Lite Edition
- of Game Maker to the Pro Edition Online. The Pro Edition has
- many aditional features.
-
Enter Activation Code. If you purchased Game Maker before (and hence, have an
- activation code or a previous purchase reference) you can use this command to enter your code.
- You will be brought to a webpage where you can either enter
- your activation code or your purchase reference from your previous payment.
-
News. Here you can see the most recent news about Game Maker.
-
Book. This command will bring you to
- a location on the website where you can find information about the Game Maker book.
-
More Tutorials. This command will bring you to
- a location on the website where you can download some more tutorials.
-
Website. Connects you to the Game Maker website
- where you can find information about the most recent version of Game
- Maker and collections of games and resources for Game Maker.
-
Forum. This command will bring you to the forum where users
- help each other with many aspects of Game Maker.
-
Wiki. This command will bring you to the Game Maker wiki where
- you can find plenty of information about the use of Game Maker.
-
About Game Maker. Gives some short information about
- this version of Game Maker.
-
-
-
The resource explorer
-
-At the left of the main form you find the resource explorer. Here you
-will see a tree-like view of all resources in your game. It works in the
-same way as the Windows Explorer, and you are most likely familiar with
-it. If an item has a + sign in front of it you can click on the sign to
-see the resources inside it. By clicking on the - sign these disappear
-again. You can change the name of a resource (except the top level ones) by
-selecting it (with a single click) and then clicking on the name. Double
-click on a resource to edit its properties. Use the right mouse button to
-access the same commands as in the Edit menu.
-
-
-You can change the order of the resources by clicking on them with the
-mouse and holding the mouse button pressed. Now you can drag the resource
-to the appropriate place. (Of course the place must be correct. You
-cannot drag a sound into the list of sprites.)

Defining sprites
-
-Sprites are the visual representations of all the objects in the game. A
-sprite is either a single image, drawn with any drawing program you like,
-or a set of images that, when played one after another, looks like an
-animated motion. For example, the following four images form a sprite for
-a character moving to the right.
-
-
-
-
-
-When you make a game you normally start by collecting a set of nice
-sprites for the objects in your game. A considerable number of useful sprites is
-bundled with Game Maker. Other collections of interesting
-sprites can be found on the Game Maker website. Many more
-sprites can be found on the web, normally in the form of png or animated gif
-files.
-
-
-To create a sprite, choose the item Create Sprite from the Resources
-menu, or use the corresponding button on the toolbar. The following form
-will pop up.
-
-
-
-
-
-At the top-left you can indicate the name of the sprite. All sprites (and all
-other resources) have a name. It's best to give each sprite a descriptive
-name. Make sure all resources get different names. Even though this is
-not strictly required, you are strongly advised to use only letters and
-digits and the underscore symbol (_) in a name of a sprite (and any other
-resource) and to let it start with a letter. In particular don't use the
-space character. This will become important once you start using code.
-
-
-To load a sprite, click on the button Load Sprite. A special file
-dialog opens in which you can choose the sprite:
-
-
-
-
-
-The left part looks like the standard file selector in which you can select the
-sprite that you want. At the right you get a preview of the animated sprite and
-some information about it. Here you can also indicate that you want to make the
-sprite opaque (that is, remove any transparent parts), whether
-to remove the background, making it transparent (default), and whether to smooth the
-edges of the sprite, which can improve its appearance. When you are happy with
-the result press Open to load the sprite.
-
-Game Maker can
-load many different graphics files. When you load an animated gif, the
-different subimages form the sprite images.
-When the file name ends with _stripXX, with XX a number, it
-is considered to contain a strip of XX subimages next to each other (not for
-gif files). For example, a image file with name ball_strip4.png is assumed to
-contain 4 subimages.
-
-
-Once the sprite is loaded
-the first subimage is shown on the right. When there are multiple sub-
-images, you can cycle through them using the arrow buttons.
-
-
-With the button Edit Sprite you can edit the sprite, or even
-create a completely new sprite. Game Maker has an extensive built-in sprite
-and image editor. For more information see the sections on
-Editing your sprites and on
-Editing individual subimages.

-Most games have certain sound effects and some background music. Many useful
-sound effects can be found on the Game Maker website. Many more can be
-found on other places on the web.
-
-
-To create a sound resource in your game, use the item Create Sound in
-the Resources menu or use the corresponding button on the toolbar.
-The following form will pop up.
-
-
-
-
-
-To load a sound, press the button labeled Load Sound.
-A file selector dialog pops up in which you can select the sound file.
-There are two types of sound files, wave files and midi files.
-Wave files are used for short sound effects. They use a lot of memory
-but play instantaneously. Use these for all the sound effects in your game.
-Midi files describe music in a different way. As a result they use a lot
-less memory, but they are limited to instrumental background music.
-Also, default only one midi sound can play at any time.
-
-
-Once you load a music file you can listen
-to the sound using the play button. There is also a button Save Sound
-to save the current sound to a file. This button is not really required
-but you might need it if you lost the original sound.

Backgrounds
-
-The third type of basic resource is backgrounds. Backgrounds are usually large images
-that are used as backgrounds (or foregrounds) for the rooms in which the game takes place.
-Often background images are made in such a way that they can tile an area without visual
-cracks. In this way you can fill the background with some pattern. A number of such
-useful backgrounds are bundled with Game Maker. Others can be found on the
-Game Maker website. Many more can be found at other places on the web.
-
-
-To create a background resource in your game, use the item Create Background
-in the Resources menu or use the corresponding button on the toolbar.
-The following form will pop up.
-
-
-
-
-
-At the top-left you can indicate the name of the background.
-You are strongly recommended to give every background (and other resource)
-a descriptive name.
-
-
-Press the button Load Background to load a background image. A file
-selector is shown in which you can select the background you want. At the
-right of the dialog you can indicate whether you want to make the
-background opaque (that is, remove any transparent parts), whether
-to remove the background, making it transparent (default not), and whether to smooth the
-edges of the background, which can improve its appearance when it is partially transparent.
-When you are happy with the result press Open to load the background.
-Game Maker supports many image formats. Background images cannot
-be animated!
-
-
-You can change the background or create a new one using the button
-Edit Background. This will open an extensive image editor. For
-information on how to use the image editor see the section on
-Editing images.
-
-
-Be careful with large backgrounds. Some old graphics cards cannot handle images that are larger
-than the screen. So preferably keep your background images smaller than 1024x1024.

Defining objects
-
-With the resources you have seen so far you can add some nice images and
-sounds to the game, but they don't do anything. We now come to the most
-important resource of Game Maker, the objects. Objects are
-entities in the game that do things. Most of the time they have a sprite
-as a graphical representation so that you see them. They have behavior
-because they can react to certain events. All things you see in the game
-(except for the background) are objects. (Or to be more precise, they are
-instances of objects.) The characters, the monsters, the balls, the
-walls, etc. are all objects. There might also be certain objects that you
-don't see but which control certain aspects of the game play.
-
-
-Please realize the difference between sprites and objects. Sprites are
-just (animated) images that don't have any behavior. Objects normally
-have a sprite to represent them but objects have behavior. Without
-objects there is no game!
-
-
-Also realize the difference between objects and instances. An object
-describes a certain entity, e.g. a monster. There can be multiple
-instances of this object in the game. When we talk about an instance we
-mean one particular instance of the object. When we talk about an object
-we mean all the instances of this object.
-
-
-To create an object in your game, choose Create Object from the Resources
-menu. The following form will appear:
-
-
-
-
-
-This is rather complex. At the left there is some general information
-about the object. In the middle there is the list of events that can
-happen to the object. At the right there are the different actions the
-object can perform. Events and actions will be discussed in the coming
-chapters.
-
-
-As always, you can (and should) give your object a name. Next you can
-choose the sprite for the object. To this end, click with the left
-mouse button on the sprite box or the menu button next to it. A menu will
-pop-up with all the available sprites. Select the one you want to use for
-the object.
-If you do not have a sprite yet, you can click the button New to
-create a new sprite resource and change it. Also, when you select a resource
-there will be a button Edit here that you can use to change the
-sprite. This is faster than first finding the resource in the list of
-resources and then indicating you want to edit it.
-
-
-Below this there are two check boxes. Visible indicates whether
-instances of this object are visible. Clearly, most objects are visible,
-but sometimes it is useful to have invisible objects. For example, you
-can use them for waypoints for a moving monster. Invisible objects will
-react to events and other instances do collide with them. The box labeled
-Solid indicates whether this is a solid object (like a wall).
-Collisions with solid objects are treated differently from collisions
-with non-solid objects. You are strongly advised to use Solid only
-for object that are not moving.

Events
-
-Game Maker uses what is called an event driven approach. This works as follows.
-Whenever something happens in the game the instances of the objects get events (kind
-of messages telling that something has happened). The instances can then react to
-these messages by executing certain actions. For each object you must indicate to
-which events it responds and what actions it must perform when the event occurs. This
-may sound complicated but is actually very easy. First of all, for most events the
-object does not have to do anything. For the events where something must be done you
-can use a very simple drag-and-drop approach to indicate the actions.
-
-
-In the middle of the object property form there is a list of events to which the
-object must react. Initially it is empty. You can add events to it by pressing the
-button labeled Add Event. A form will appear with all different types of
-events. Here you select the event you want to add. Sometimes a menu pops up with extra
-choices. For example, for the keyboard event you must select the key. Below you find a
-complete list of the different events plus descriptions. One event in the list will be
-selected. This is the event we are currently changing. You can change the selected
-event by clicking on it. At the right there are all the actions represented by little
-icons. They are grouped in a number of tabbed pages. In the next chapter you will find
-descriptions of all the actions and what they do. Between the events and the actions
-there is the action list. This list contains the actions that must be performed for
-the current event. To add actions to the list, drag them with your mouse from the
-right to the list. They will be placed below each other, with a short description. For
-each action you will be asked to provide a few parameters. These will also be
-described in the next chapter. So after adding a few actions the situation might look
-as follows:
-
-
-
-
-
-Now you can start adding actions to another event. Click on the correct event with the
-left mouse button to select it and drag actions in the list.
-
-
-You can change the order of the actions in the list again using drag-and-drop. If you
-hold the <Alt> key while dragging, you make a copy of the action. You can even
-use drag-and-drop between action lists for different objects. When you click with the
-right mouse button on an action, a menu appears in which you can delete the selected action
-(can also be done by using the <Del> key) or copy and paste actions. (You can
-select multiple actions for cutting, copying, or deleting by holding the
-<Shift> key of <Ctrl> key. Press <Ctrl><A> to select
-all actions.) When you
-hold your mouse at rest above an action, a longer description is given of the action.
-See the next chapter for more information on actions.
-
-
-To delete the currently selected event together with all its actions press the button
-labeled Delete. (Events without any actions will automatically be deleted when
-you close the form so there is no need to delete them manually.) If you want to assign
-the actions to a different event (for example, because you decided to use a different
-key for them) press the button labeled Change and pick the new event you want.
-(The event should not be defined already!) Using the menu that pops up when right-clicking
-on the event list, you can also duplicate an event, that is, add a new event with the
-same actions.
-
-
-As indicated above, to add an event, press the button Add Event. The following
-form pops up:
-
-
-
-
-
-Here you select the event you want to add. Sometimes a menu pops up with extra
-choices. Here is a description of the various events. (Again remember that you
-normally use only a few of them.)
-
-
- Create event
-This event happens when an instance of the object is created. It is normally used to
-set the instance in motion and/or to set certain variables for the instance.
-
-
- Destroy event
-This event happens when the instance is destroyed. To be precise, it happens just
-before it is destroyed, so the instance does still exist when the event is executed!
-Most of the time this event is not used but you can for example use it to change the score or
-to create some other object.
-
-
- Alarm events
-Each instance has 12 alarm clocks.
-You can set these alarm clocks using certain actions
-(see next chapter). The alarm clock then ticks down until it reaches 0 at which moment
-the alarm event is generated. To indicate the actions for a given alarm clock, you
-first need to select it in the menu. Alarm clocks are very useful. You can use them to
-let certain things happen from time to time. For example a monster can change its
-direction of motion every 20 steps. (In such cases one of the actions in the event
-must set the alarm clock again.)
-
-
- Step events
-The step event happens every step of the game. Here you can put actions that need to
-be executed continuously. For example, if one object should follow another, here you
-can adapt the direction of motion towards the object we are following. Be careful with
-this event though. Don't put many complicated actions in the step event of objects of
-which there are many instances. This might slow the game down. To be more precise,
-there are three different step events. Normally you only need the default one. But
-using the menu you can also select the begin step event and the end step event. The
-begin step event is executed at the beginning of each step, before any other events
-take place. The normal step event is executed just before the instances are put in
-their new positions. The end step event is executed at the end of the step, just
-before the drawing. This is typically used to change the sprite depending on
-the current direction.
-
-
- Collision events
-Whenever two instances collide (that is, their sprites overlap) a collision event
-appears. Well, to be precise two collision event occur; one for each instance. The
-instance can react to this collision event. To this end, from the menu select the
-object with which you want to define the collision event. Next you place the actions
-here.
-
-
-There is a difference in what happens when the instance collides with a solid object
-or a non-solid object. First of all, when there are no actions in the collision event,
-nothing happens. The current instance simply keeps on moving; even when the other
-object is solid. When the collision event contains actions the following happens:
-
-
-When the other object is solid, the instance is placed back at its previous place
-(before the collision occurs). Then the event is executed. Finally, the instance is
-moved to its new position. So if the event e.g. reverses the direction of motion, the
-instance bounces against the wall without stopping. If there is still a collision, the
-instance is kept at its previous place. So it effectively stops moving.
-
-
-When the other object is not solid, the instance is not put back. The event is simply
-executed with the instance at its current position. Also, there is no second check for
-a collision. If you think about it, this is the logical thing that should happen.
-Because the object is not solid, we can simply move over it. The event notifies us
-that this is happening.
-
-
-There are many uses for the collision event. Instances can use it to bounce against
-walls. You can use it to destroy objects when, for example, they are hit by a bullet.
-
-
- Keyboard events
-When the player presses a key, a keyboard event happens for all instances of all
-objects. There is a different event for each key. In the menu you can pick the key for
-which you want to define the keyboard event and next drag actions there. Clearly, only
-a few objects need events for only a few keys. You get an event in every step as long
-as the player keeps the key depressed. There are two special keyboard events. One is called
-<No key>. This event happens in each step when no key is pressed. The second one
-is called <Any key> and happens whatever key is pressed. When the player
-presses multiple keys, the events for all the keys pressed happen. Note that the keys
-on the numeric keypad only produce the corresponding events when <NumLock> is
-pressed.
-
-
- Mouse events
-A mouse event happens for an instance whenever the mouse cursor lies inside the sprite
-representing the instance. Depending on which mouse buttons are pressed you get the no
-button, left button, right button, or middle button event. The mouse button events are
-generated in each step as long as the player keeps the mouse button pressed. The press
-events are only generated once when the button is pressed. The release events are only
-generated when the button is released. Note that these events only occur when the
-mouse is above the instance. If you want to react to mouse press or release events at
-an arbitrary place, use the global mouse events that can be found in a submenu. There are
-two special mouse events. The mouse enter event happens when the mouse enters the
-instance. The mouse leave event happens when the mouse leaves the instance. These
-events are typically used to change the image or play some sound.
-Mouse wheel up and mouse wheel down events happen when the user moves the mouse wheel.
-Finally there are a
-number of events related to the joystick. You can indicate actions for the four main
-directions of the joystick (in a diagonal direction both events happen). Also you can
-define actions for up to 8 joystick buttons. You can do this both for the primary
-joystick and the secondary joystick.
-
-
- Other events
-There are a number of other events that can be useful in certain games. They are found
-in this menu. The following events can be found here:
-
-
-
Outside room: This event happens when the instance lies completely outside the
- room. This is typically a good moment to destroy it.
-
Intersect boundary: This event happens when the instance intersects the boundary of
- the room, that is, it lies (at least) partially outside the room.
-
Views: Here you find a number of events that are useful when you use
- views in your rooms. These events test whether the instance lies completely outside
- a particular view or interesects the view boundary.
-
Game start: This event happens for all instances in the first room when
- the game starts. It happens before the room start event (see below) but after the
- creation events for the instances in the room. This event is typically defined in only
- one "controller" object and is used to start some background music and to
- initialize some variables, or load some data.
-
Game end: The event happens to all instances when the game ends. Again
- typically just one object defines this event. It is for example used to store certain
- data in a file.
-
Room start: This event happens for all instances initially in a room when
- the room starts. It happens after the creation events.
-
Room end: This event happens to all existing instances when the room ends.
-
No more lives: Game Maker has a built-in lives system. There is an
- action to set and change the number of lives. Whenever the number of lives becomes
- less than or equal to 0, this event happens. It is typically used to end or restart
- the game.
-
No more health: Game Maker has a built-in health system. There is
- an action to set and change the health. Whenever the health becomes less than or equal
- to 0, this event happens. It is typically used to reduce the number of lives or to
- restart the game.
-
Animation end: As indicated above, an animation consists of a number
- of images that are shown one after the other. After the last one is shown we start
- again with the first one. The event happens at precisely that moment. As an example,
- this can be used to change the animation, or destroy the instance.
-
End of path: This event happens when the instance follows a path and the
- end of the path is reached.
-
Close button: This event happens when the user clicks on the close button
- of the window. This only happens when disabling in the game settings the option to have
- the close button behave as the Escape key.
-
User defined: There are 16 of these events. They normally never happen
- unless you yourself call them from a piece of code.
-
-
-
- Draw event
-Instances, when visible, draw their sprite in each step on the screen. When you
-specify actions in the drawing event, the sprite is not drawn, but these actions are
-executed instead. This can be used to draw something other than the sprite, or first
-make some changes to sprite parameters. There are a number of drawing actions that are
-especially meant for use in the drawing event. Note that the drawing event is only
-executed when the object is visible. Also note that, independent of what you draw,
-collision events are based on the sprite that is associated with the instance.
-
-
- Key Press events
-This event is similar to the keyboard event but it happens only once when the key
-is pressed, rather than continuously. This is useful when you want an action to
-happen only once.
-
-
- Key Release events
-This event is similar to the keyboard event but it happens only once
-when the key is released, rather than continuously.
-
-
-In some situation it is important to understand the order in which
-Game Maker processes the events. This is as follows:
-
-
-
Begin step events
-
Alarm events
-
Keyboard, Key press, and Key release events
-
Mouse events
-
Normal step events
-
(now all instances are set to their new positions)
-
Collision events
-
End step events
-
Draw events
-
-
-
-The create, destroy, and other events are performed when the corresponding things
-happen.

Actions
-
-Actions indicate the things that happen in a game created with Game Maker.
-Actions are placed in events of objects. Whenever the event takes place these
-actions are performed, resulting in certain behavior for the instances of the object.
-There are a large number of different actions available and it is important
-that you understand what they do. In this chapter we describe the actions
-available in simple mode. Note that a number of these actions are only available
-in the Pro Edition of Game Maker. This will be indicated.
-
-
-All the actions are found in the tabbed pages at the right of the object property form.
-There are six sets of actions. You select the set you want by clicking on the correct tab.
-When you hold you mouse above one of the actions, a short description is
-shown to remind you of its function.
-
-
-Let us briefly repeat: To put an action in an event, just drag it from the
-tabbed pages to the action list. You can change the order in the list, again
-using dragging. Holding the <Alt> key while dragging makes a copy of
-the action. (You can drag and copy actions between the lists in
-different object property forms.) Use the right mouse button and select the
-correct menu item to remove actions
-(or use the <Del> key) and to copy and paste selected actions.
-
-
-When you drop an action in the action list, a window will pop-up most
-of the time, in which you can fill in certain parameters for the action.
-The parameters will be described below when describing the actions.
-Two types of parameters appear in many actions so we will describe these here.
-At the top you can indicate to which instance the action applies. The default
-is self, which is the instance for which the action is performed.
-Most of the time, this is what you want. In the case of a collision event,
-you can also specify to apply the action to the other instance
-involved in the collision. For instance, in this way you can destroy the
-other instance. Finally, you can choose to apply the action to all
-instances of a particular object. In this way you could change all
-red balls into blue balls. The second type of parameter is the
-box labeled Relative. By checking this box, the values you
-type in are relative to the current values. For example, in this way
-you can add something to the current score, rather than changing
-the current score to the new value. The other parameters will be
-described below. You can later change the parameters by double
-clicking on the action.
-
-

Move actions
-
-The first set of actions consists of those related to movement of objects.
-The following actions exist:
-
-
- Move Fixed
-Use this action to start the instance moving in a particular direction.
-You can indicate the direction using the buttons with the arrows on it.
-Use the middle button to stop the motion. Also you need to specify
-the speed of the motion. This speed is given in pixels per step.
-Preferably don't use negative speeds.
-You can specify multiple directions. In this case a random choice is made.
-In this way you can let a monster start moving either left or right.
-
-
- Move Free
-This is the second way to specify a motion. Here you can indicate a precise direction.
-This is an angle between 0 and 360 degrees. 0 means to the right.
-The direction is counter-clockwise. So for example 90 indicates an
-upward direction. If you want an arbitrary direction, you can type
-random(360). As you will see below the function random gives
-a random number smaller than the indicated value. As you might have noticed there
-is a checkbox labeled Relative. If you check this, the new motion is added
-to the previous one. For example, if the instance is moving upwards and you
-add some motion to the left, the new motion will be upwards to the left.
-
-
- Move Towards
-This action gives a third way to specify a motion. You indicate a position and
-a speed and the instance starts moving with the speed towards the position.
-(It won't stop at the position!) For example, if you want a bullet to fly
-towards the position of the spaceship you can use as position spaceship.x, spaceship.y.
-(You will learn more about the use of variables like these below.)
-If you check the Relative box, you specify the position relative
-to the current position of the instance. (The speed is not taken relatively!)
-
-
- Speed Horizontal
-The speed of an instance consists of a horizontal part and a vertical part.
-With this action you can change the horizontal speed. A positive horizontal
-speed means a motion to the right. A negative one means a motion to the left.
-The vertical speed will remain the same. Use relative to increase the horizontal speed
-(or decrease it by providing a negative number).
-
-
- Speed Vertical
-In a similar way, with this action you can change the vertical speed of the instance.
-
-
- Set Gravity
-With this action you can create gravity for this particular object.
-You specify a direction (angle between 0 and 360 degrees) and a speed,
-and in each step this amount of speed in the given direction is added
-to the current motion of the object instance. Normally you need a very
-small speed increment (like 0.01). Typically you want a downward direction
-(270 degrees). If you check the Relative box you increase the
-gravity speed and direction. Note that, contrary to real life,
-different object can have different gravity directions.
-
-
- Reverse Horizontal
-With this action you reverse the horizontal motion of the instance.
-This can for example be used when the object collides with a vertical wall.
-
-
- Reverse Vertical
-With this action you reverse the vertical motion of the instance.
-This can for example be used when the object collides with a horizontal wall.
-
-
- Set Friction
-Friction slows down the instances when they move. You specify the amount
-of friction. In each step this amount is subtracted from the speed
-until the speed becomes 0. Normally you want a very small number here (like 0.01).
-
-
- Jump to Position
-Using this action you can place the instance in a particular position.
-You simply specify the x- and y-coordinate, and the instance is placed
-with its reference point on that position. If you check the Relative box,
-the position is relative to the current position of the instance.
-This action is often used to continuously move an instance.
-In each step we increment the position a bit.
-
-
- Jump to Start
-This action places the instance back at the position where it was created.
-
-
- Jump to Random
-This action moves the instance to a random position in the room.
-Only positions are chosen where the instance does not intersect any
-solid instance. You can specify the snapping used. If you specify
-positive values, the coordinates chosen with be integer multiples of
-the indicated values. This could for example be used to keep the instance
-aligned with the cells in your game (if any). You can specify a separate
-horizontal snapping and vertical snapping.
-
-
- Align to Grid
-With this action you can round the position of the instance to a grid.
-You can indicate both the horizontal and vertical snapping value (that is,
-the size of the cells of the grid). This can be very useful to make sure
-that instances stay on a grid.
-
-
- Wrap Screen
-With this action you can let an instance wrap around, that is, when
-it leaves on one side of the room it reappears at the other side. This
-action is normally used in the Outside event. Note that the
-instance must have a speed for wrapping to work, cause the direction
-of wrapping is based on the direction of the motion. You can indicate
-whether to wrap only horizontal, only vertical, or in both directions.
-
-
- Move to Contact
-With this action you can move the instance in a given direction until a
-contact position with an object is reached. If there already is a collision
-at the current position the instance is not moved. Otherwise, the instance
-is placed just before a collision occurs. You can specify the direction but
-also a maximal distance to move. For example, when the instance is falling
-you can move a maximal distance down until an object is encountered. You can
-also indicate whether to consider solid object only or all objects. You typically
-put this action in the collision event to make sure that the instance stops
-in contact with the other instance involved in the collision.
-

- Bounce
-When you put this action in the collision event with some object, the instance
-bounces back from this object in a natural way. If you set the parameter precise
-to false, only horizontal and vertical walls are treated correctly. When you set
-precise to true also slanted (and even curved) walls are treated correctly.
-This is though slower. Also you can indicate whether to bounce only against solid
-objects or against all objects. Please realize that the bounce is not completely
-accurate because this depends on many properties. But in many situations the
-effect is good enough.

Main actions, set 1
-
-The following set of actions deals with creating, changing, and destroying instances of
-objects, with sounds, and with rooms.
-
-
- Create Instance
-With this action you can create an instance of an object. You specify which
-object to create and the position for the new instance. If you check the Relative box,
-the position is relative to the position of the current instance. Creating
-instances during the game is extremely useful. A space ship can create bullets;
-a bomb can create an explosion, etc. In many games you will have some controller
-object that from time to time creates monsters or other objects. For the newly
-created instance the creation event is executed.
-
-
- Create Moving
-This action works the same as the action above but with two additional fields.
-You can now also specify the speed and direction of the newly created instance.
-Note that if you check the Relative box, only the position is relative,
-not the speed and direction. For example, to make a bullet move in the direction
-of the person shooting you have to use a little trick. As position use
-0,0 and check Relative. As direction we need the current direction
-of the instance. This can be obtained by typing in the word direction.
-(This actually is a variable that always indicates the current direction
-in which the instance is moving.)
-
-
- Create Random
-This action lets you create an instance of one out of four objects. You specify
-the four objects and the position. An instance of one of these four objects
-is created at the given position. If you check the Relative box,
-the position is relative to the position of the current instance. If you need
-a choice out of less than four objects you can use No Object for some of them.
-This is for example useful to generate a random enemy at a location.
-
-
- Change Instance
-With this action you can change the current instance into an instance of
-another object. So for example, you can change an instance of a bomb into
-an explosion. All settings, such as the motion and the value of variables,
-will stay the same. You can indicate whether or not to perform the destroy
-event for the current object and the creation event for the new object.
-
-
- Destroy Instance
-With this action you destroy the current instance. The destroy event
-for the instance is executed.
-
-
- Destroy at Position
-With this action you destroy all instances whose bounding box contains a
-given position. This is useful, for example, when you use an exploding bomb.
-When you check the Relative box the position is taken relative to
-the position of the current instance.
-
-
- Change Sprite
-Use this action to change the sprite for the instance. You indicate which new sprite.
-You can also indicate with subimage must be shown. Normally you would use 0 for
-this (the first subimage) unless you want to see a particular subimage. Use -1 if
-you do not want to change the current subimage shown. Finally
-you change the speed of the animation of the subimages. If you only want to see
-a particular subimage, set the speed to 0. If the speed is larger than one
-subimages will be skipped. If it is smaller than 1 subimages will be shown
-multiple times. Don't use a negative speed. Changing sprites is an important feature.
-For example, often you want to change the sprite of a character depending on
-the direction in which it walks. This can be achieved by making different sprites
-for each of the (four) directions. Within the keyboard events for the arrow keys
-you set the direction of motion and the sprite.
-
-
- Transform Sprite
-Use this action to change the size and orientation of the sprite for the instance.
-Use the scale factors to make it larger or smaller. The angle gives the counter-clockwise
-orientation of the sprite. For example, to make the sprite oriented in the direction of
-motion use as a value direction. For example, this is useful for a car. You can also
-indicate whether the sprite should be mirrored horizontally and/or flipped vertically.
-This action is only available in the Pro Edition.
-
-
- Color Sprite
-Normally the sprite is drawn as it is defined. Using this action you can change the
-color of the sprite. This color is blended with the sprite, that is, it is combined
-with the colors of the sprite. If you want to draw a sprite in different colors you
-better define the sprite in black and white and use the blend color to set the
-actual color. You can also indicate an alpha transparency. With a value of 1 the
-sprite is opaque. With a value of 0 it is completely transparent. With a value in
-between you will partially see the background shine through it. This is great for
-making explosions.
-This action is only available in the Pro Edition.
-
-
- Play Sound
-With this action you play one of the sound resources you added to your game.
-You can select the sound you want to play and choose whether it should play only once
-(the default) or loop continuously. Multiple wave sounds can play at once but
-only one midi sound can play at a time. So if you start a midi sound, the current midi
-sound is stopped.
-
-
- Stop Sound
-This action stops the indicated sound. If multiple instances of this sound
-are playing all are stopped.
-
-
- Check Sound
-If the indicated sound is playing the next action is performed. Otherwise
-it is skipped. You can select Not to indicate that the next action
-should be performed if the indicated sound is not playing. For example,
-you can check whether some background music is playing and, if not, start
-some new background music.
-Note that this action returns true when the sound actually plays through the speakers. After you call the
-action to play a sound it does not immediately reach the speakers so the action
-might still return false for a while. Similar, when the sound is stopped you still hear
-it for a while (e.g. because of echo) and the action will still return true.
-
-
- Previous Room
-Move to the previous room. You can indicate the type of transition effect
-between the rooms. You should experiment to see what works best for you. When the rooms do
-not have the same size you better do not use transitions.
-If you are in the first room you get an error.
-
-
- Next Room
-Move to the next room. You can indicate the transition.
-
-
- Restart Room
-The current room is restarted. You indicate the transition effect.
-
-
- Different Room
-With this action you can go to a particular room. You indicate the room and the
-transition effect.
-
-
- Check Previous
-This action tests whether the previous room exists. If so, the next action
-is executed. You normally need this test before moving to the previous room.
-
-
- Check Next
-This action tests whether the next room exists. If so, the next action
-is executed. You normally need this test before moving to the next room.

Main actions, set 2
-
-Here are some more main actions, dealing with timing, giving messages to the user,
-and dealing with the game as a whole.
-
-
- Set Alarm
-With this action you can set one of the twelve alarm clocks for the instance.
-You select the number of steps and the alarm clock. After the indicated
-number of steps, the instance will receive the corresponding alarm event.
-You can also increase or decrease the value by checking the Relative box.
-If you set the alarm clock to a value less than or equal to 0 you switch it off,
-so the event is not generated.
-
-
- Sleep
-With this action you can freeze the scene for a particular time.
-This is typically used at the beginning or end of a level or when
-you give the player some message. You specify the number of milliseconds to sleep.
-Also you can indicate whether the screen should first be redrawn to
-reflect the most recent situation.
-
-
- Display Message
-With this action you can display a message in a dialog box. You simply type in
-the message. If you use a # symbol in the message text it will be interpreted
-as a new line character. (Use \# to get the # symbol itself.) If the message
-text starts with a quote or double quote symbol, it is interpreted as an
-expression. See below for more information about expressions.
-
-
- Show Info
-With this action you pop up the game information window.
-
-
- Restart Game
-With this action you restart the game from the beginning.
-
-
- End Game
-With this action you end the game.
-
-
- Save Game
-With this action you can save the current game status. You specify the
-filename for saving (the file is created in the working directory for
-the game). Later the game can be loaded with the next action. (Please
-realize that only the basic game status is save. Things that are for
-example not saved are the current sound that is playing, and advanced
-aspects like the contents of data structures, particles, etc.)
-
-
- Load Game
-Load the game status from a file. You specify the file name. Make sure
-the saved game is for the same game and created with the same version
-of Game Maker. Otherwise an error will occur. (To be precise,
-the game is loaded at the end of the current step. So some actions after
-this one are still executed in the current game, not the loaded one!)

Control actions
-
-There are a number of actions with which you can control which other actions are performed.
-Most of these actions ask a question, for example whether a position is empty.
-When the answer is yes (true) the next action is executed, otherwise it is skipped.
-If you want multiple actions to be executed or skipped based on the outcome you
-can put them in a block by putting start block and end block actions
-around them. There can also be an else part which is executed when the
-answer is no. So a question typically looks as follows:
-
-
-
-
-
-Here the question is asked whether a position for the current
-instance is collision free. If so, the instance starts moving in a given direction.
-If not, the instance jumps to a given position. Note that the blocks are indented.
-This gives a better overview of the actions. (In particular when you use blocks inside blocks.)
-Also it is easier to detect when you forgot a start block or end block action.
-
-
-For all questions there is a field labeled NOT. If you check this field,
-the result of the question is reversed. That is, if the result was true it becomes
-false and if it was false, it becomes true. This allows you to perform certain
-actions when a question is not true.
-
-
-For many questions you can indicate that they should apply to all instances
-of a particular object. In this case the result is true only if it is true
-for all instances of the object. For example, you can check whether for all
-balls the position slightly to the right is collision free.
-
-
-The following questions and related actions are available. (Note that they all have
-a differently shaped icon and a different background color so that they can
-more easily be distinguished from other actions.)
-
-
- Check Empty
-This question returns true if the current instance, placed at the indicated
-position does not generate a collision with an object. You can specify the
-position as either absolute or relative. You can also indicate whether only solid,
-or all objects, should be taken into account.
-This action is typically used to check whether the instance can move to a
-particular position.
-
-
- Check Collision
-This is the reverse of the previous action. It returns true if there is a collision
-when the current instance is placed at the given position (again, either only with
-solid objects or with all objects).
-
-
- Check Object
-This question returns true if the instance placed at the indicate position meets
-an instance of the indicated object.
-
-
- Test Instance Count
-You specify an object and a number. If the current number of instances of the
-object is equal to the number the question returns true. Otherwise it returns
-false. You can also indicate that the check should be whether the number of
-instances is smaller than the given value or larger than the given value. This
-is typically used to check whether all instances of a particular type are gone.
-This is often the moment to end a level or a game.
-
-
- Test Chance
-You specify the number of sides of a dice which is then thrown. Then if the dice lands on one,
-the result is true and the next action is performed. This can be used to put
-an element of randomness in your game. For example, in each step you can
-generate with a particular chance a bomb or a change of direction. The larger the
-number of sides of the dice, the smaller the chance. You can actually use
-real numbers. For example if you set the number of sides to 1.5 the next
-action is performed two out of three times. Using a number smaller than 1 makes no sense.
-
-
- Check Question
-You specify a question. A dialog is shown to the player with a yes and a no
-button. The result is true is the player answers yes.
-
-
- Test Expression
-This is the most general question action. You can enter an arbitrary expression.
-If the expression evaluates to true (that is, a number larger or equal to 0.5)
-the next action is performed. See below for more information on expressions.
-
-
- Check Mouse
-Returns true if the indicated mouse button is pressed. A standard use is in
-the step event. You can check whether a mouse button is pressed and, if so,
-for example move to that position (use the jump to a point action with
-values mouse_x and mouse_y).
-
-
- Check Grid
-Returns true if the position of the instance lies on a grid. You
-specify the horizontal and vertical spacing of the grid. This is
-very useful when certain actions, like making a turn, are only a
-llowed when the instance is on a grid position.
-
-
- Start Block
-Indicates the start of a block of actions.
-
-
- End Block
-Indicates the end of a block of actions.
-
-
- Else
-Behind this action the else part follows, that is executed when
-the result of the question is false.
-
-
- Repeat
-This action is used to repeat the next action (or block of actions)
-a number of times. You simply indicate the number.
-
-
- Exit Event
-When this action is encountered no further actions in this event are
-executed. This is typically used after a question. For example, when
-a position is free nothing needs to be done so we exit the event. In
-this example, the following actions are only executed when there is
-a collision.
-
-
-
-If you want more control over what is happening in the game you can use the
-built-in programming language that is described in Part 4 of the documentation.
-If gives you much more flexibility than using the actions. There are also actions
-to define and test variables. They are simpler to use than code and can be very useful for your games.
-The following actions deal with this.
-
-
- Execute Code
-When you add this action, a form shows in which you can type a piece of code
-which must be execute. This can contain simple function calls or more complex
-code. Use the code action preferably only for small pieces of code.
-For longer pieces you are strongly advised to use scripts which are described
-in Part 2 of the documentation.
-
-
- Comment
-Use this action to add a line of comment to the action list.
-The line is shown in italic font. Adding comments helps you remember
-what your events are doing.
-The action does not do anything. But realize that it still is an action.
-So when you place it after a conditional action it is the action that is executed
-if the condition is true (even though it does not do anything).
-
-
- Set Variable
-There are many built-in variables in the game. With this action you can change these.
-Also you can create your own variables and assign values to them. You specify the
-name of the variable and the new value. When you check the Relative box,
-the value is added to the current value of the variable. Please note that this
-can only be done if the variable already has a value assigned to it! See below
-for more information about variables.
-
-
- Test Variable
-With this action you can check what the value of a particular variable is.
-If the value of the variable is equal to the number provided, the question
-returns true. Otherwise it returns false. You can also indicate that the
-check should be whether the value is smaller than the given value or larger
-than the given value. See below for more information about variables.
-Actually, you can use this action also to compare two expressions.
-
-
- Draw Variable
-With this action you can draw the value of a variable at a
-particular position on the screen. Note that this can only be used
-in the draw event of an object.

Score actions
-
-In most games the player will have a certain score. Also many games give the player
-a number of lives. Finally, often the player has a certain health. The following
-actions make it easy to deal with the score, lives, and health of the player.
-
-
- Set Score
-Game Maker has a built-in score mechanism. The score is normally
-displayed in the window caption. You can use this action to change the score.
-You simply provide the new value for the score. Often you want to add something
-to the score. In this case don't forget the check the Relative box.
-
-
- Test Score
-With this question action you can check whether the score has reached a particular
-value. You indicate the value and whether the score should be equal to that value,
-be smaller than the value or be larger than the value.
-
-
- Draw Score
-With this action you can draw the value of the score at a particular position on
-the screen. You provide the positions and the caption that must be placed in front
-of the score. The score is drawn in the current font. This action can only be used
-in the drawing event of an object.
-
-
- Show Highscore
-For each game the top ten scores are maintained. This action displays the highscore
-list. If the current score is among the top ten, the new score is inserted and the
-player can type his or her name.
-You can indicate what background image to use, whether the window
-should have a border, what the color for the new entry and the other entries must be,
-and which font to use.
-
-
- Set Lives
-Game Maker also has a built-in lives system. With this action you can
-change the number of lives left. Normally you set it to some value like 3 at
-the beginning of the game and then decrease or increase the number depending
-on what happens. Don't forget to check the Relative box if you want to
-add or subtract from the number of lives. At the moment the number of lives
-becomes 0 (or smaller than 0) a "no more lives" event is generated.
-
-
- Test Lives
-With this question action you can check whether the number of lives has reached
-a particular value. You indicate the value and whether the number of lives should
-be equal to that value, be smaller than the value or be larger than the value.
-
-
- Draw Lives
-With this action you can draw the number of lives at a particular position on
-the screen. You provide the positions and the caption that must be placed in
-front of the number of lives. The number of lives is drawn in the current font.
-This action can only be used in the drawing event of an object.
-
-
- Draw Life Images
-Rather than drawing the number of lives left as a number, it is often nicer to
-use a number of small images for this. This action does precisely that. You
-specify the position and the image and at the indicated position the number of
-lives is drawn as images. This action can only be used in the drawing event of an object.
-
-
- Set Health
-Game Maker has a built-in health mechanism. You can use this action to
-change the health. A value of 100 is considered full health and 0 is no health
-at all. You simply provide the new value for the health. Often you want to
-subtract something from the health. In this case don't forget the check the
-Relative box. When the health becomes smaller or equal to 0 an out
-of health event is generated.
-
-
- Test Health
-With this question action you can check whether the health has reached a
-particular value. You indicate the value and whether the health should be
-equal to that value, be smaller than the value or be larger than the value.
-
-
- Draw Health
-With this action you can draw the health in the form of a health bar. When
-the health is 100 the full bar is drawn. When it is 0 the bar is empty. You
-indicate the position and size of the health bar and the color of the bar
-and the background.
-
-
- Score Caption
-Normally in the window caption the name of the room and the score is displayed.
-With this action you can change this. You can indicate whether or not to show
-the score, lives, and/or health and what the caption for each of these must be.

Draw actions
-
-Normally in each step of the game, for each instance, its sprite is drawn in the room.
-You can change this by putting actions in the draw event. (Note that these are only
-executed when the instance is visible!) The following drawing actions are available.
-These actions only make sense in the drawing event. At other places they are
-basically ignored.
-
-
- Draw Sprite
-You specify the sprite, the position (either absolute or relative
-to the current instance position) and the subimage of the sprite.
-(The subimages are numbered from 0 upwards.) If you want to
-draw the current subimage, use number -1.
-
-
- Draw Background
-You indicate the background image, the position (absolute or relative) and
-whether the image should be tiled all over the room or not.
-
-
- Draw Text
-You specify the text and the position. A # symbol in the text is interpreted
-as going to a new line. (Use \# to get the # symbol itself.) So you can
-create multi-line texts. If the text starts with a quote or a double quote,
-it is interpreted as an expression. For example, you can use
-
-
-'X: ' + string(x)
-
-
-
-to display the value of the x-coordinate of the instance.
-(The variable x stores the current x-coordinate. The function string() turns
-this number into a string. + concatenates the two strings.)
-
-
- Draw Scaled Text
-This action is similar to the previous action but this time you can also
-specify a horizontal and vertical scaling factor to change the size of the
-text and you can specify an angle to rotate it.
-This action is only available in the Pro Edition.
-
-
- Draw Rectangle
-You specify the coordinates of the two opposite corners of the rectangle;
-either absolute or relative to the current instance position.
-
-
- Horizontal Gradient
-This action also draws a rectangle but this time using a gradient color that
-changes from left to right. You specify the rectangle and the two colors to use.
-This action is only available in the Pro Edition.
-
-
- Vertical Gradient
-This action also draws a rectangle but this time using a gradient color that
-changes from top to bottom. You specify the rectangle and the two colors to use.
-This action is only available in the Pro Edition.
-
-
- Draw Ellipse
-This action draws an ellipse.
-You specify the coordinates of the two opposite corners of the surrounding
-rectangle; either absolute or relative to the current instance position.
-
-
- Gradient Ellipse
-Again an ellipse is drawn but this time you specify a color for the center and
-the boundary.
-This action is only available in the Pro Edition.
-
-
- Draw Line
-You specify the coordinates of the two endpoints of the line; either
-absolute or relative to the current instance position.
-
-
- Draw Arrow
-Draws an arrow. You specify the coordinates of the two endpoints of the line
-and the size of the arrow tip.
-
-
- Set Color
-Lets you set the color used for drawing shapes, lines, and text.
-(It does not influence the way sprites and backgrounds are drawn.)
-
-
- Set Full Screen
-With this action you can change the screen mode from windowed to fullscreen
-and back. You can indicate whether to toggle the mode or whether to go to
-windowed or fullscreen mode.
-
-
- Take Snapshot
-With this action you can take a snapshot image of the game and store
-it in a .png file. You specify the filename to store the image in.
-This action is only available in the Pro Edition.
-
-
- Create Effect
-With this action you can create all sorts of effects in a very simple way. You
-specify the type of effect, e.g. an explosion or smoke, its position, its size and its color and
-whether it should be shown below the objects or on top of them. For the
-rest it works automatic. (For rain and snow the position is irrelevant
-as it always falls down from the top of the screen. To get continuous
-rain you should create it in each step.) Please note that below actually means
-at a depth of 100000 and above means at a depth of -100000.
-This action is only available in the Pro Edition.

Using expressions and variables
-
-In many actions you need to provide values for parameters. Rather than just
-typing a number, you can also type a formula, e.g. 32*12. But you can actually
-type much more complicated expressions. For example, if you want to double the
-horizontal speed, you could set it to 2*hspeed. Here hspeed is a
-variable indicating the current horizontal speed of the instance.
-There are a large number of other variables that you can use.
-Some of the most important ones are:
-
-
-
- x the x-coordinate of the instance
- y the y-coordinate of the instance
- hspeed the horizontal speed (in pixels per step)
- vspeed the vertical speed (in pixels per step)
- direction the current direction of motion in degrees (0-360)
- speed the current speed in this direction
- visible whether the object is visible (1) or invisible (0)
- image_index this variable indicate which subimage in the current sprite is currently shown.
- If you change it and set the speed to 0 (see below) you can display a fixed subimage.
- image_speed this variable indicates the speed with which the subimages are shown.
- The default value is 1. If you make this value larger than 1 some subimages
- are skipped to make the animation faster. If you make it
- smaller than 1 the animation becomes slower by repeating subimages.
- score the current value of the score
- lives the current number of lives
- health the current health (0-100)
- mouse_x x-position of the mouse
- mouse_y y-position of the mouse
-
-
-You can change most of these variables using the set variable action.
-You can also define your own variables by setting them to a value.
-(Don't use relative, because they don't exist yet.) Then you can use these
-variables in expressions. Variables you create are local to the current
-instance. That is, each object has its own copy of them. To create a global
-variable, put the word global and a dot in front of it.
-
-
-You can also refer to the values of variables for other objects
-by putting the object name and a dot in front of them. So for example,
-if you want a ball to move to the place where the coin is you can
-set the position to (coin.x , coin.y). In the
-case of a collision event you can refer to the x-coordinate of the
-other object as other.x. In conditional expressions you
-can use comparisons like < (smaller than), >, etc.
-
-
-In your expressions you can also use functions. For example, the function
-random(10) gives a random integer number below 10. So you can
-set for example the speed or direction of motion to a random value.
-Many more functions exist. They are described in Part 4 of the
-documentation.

Creating rooms
-
-Now that you have defined the objects with their behavior in the form of events and
-actions, it is time to create the rooms or levels in which the game takes place. Any
-game will need at least one room. In these rooms we place instances of the objects.
-Once the game starts the first room is shown and the instances in it come to life
-because of the actions in their creation events.
-
-
-There are a large number of possibilities when creating rooms. Besides setting a
-number of properties and adding the instances of the objects you can add backgrounds,
-define views, and add tiles. Most of these options are discussed later.
-In this chapter we will only discuss some basic settings, the addition of instances of
-objects, and the setting of background images.
-
-
-To create a room, choose Create Room from the Resources menu. The following form
-will appear:
-
-
-
-
-
-At the top of the form there is a tool bar. On this you can indicate the size of the
-grid cells used for aligning objects. Also you can indicate whether or not to show the
-grid lines and whether or not to show the backgrounds, etc. It is
-sometimes useful to temporarily hide certain aspects of the room. Realize though that
-when you are adding instances of objects, these will always be shown, independent of
-the view setting.) There are also buttons to clear all instances from the room and to
-shift all instances over a number of pixels. Use negative numbers to shift them left
-or up. This is useful when for instance you decided to enlarge the room. (You can also use
-this to place instances outside the room, which is sometimes useful.). Finally there
-is the Undo button to undo the last change to the room and the OK button
-to save the changes. (Click on the cross at the top right to close the form without
-saving the changes.)
-
-
-At the left you will see three tab pages (five in advanced mode). The objects
-tab is where you add instances of objects to the room. In the settings tab you
-can indicate a number of settings for the room. In the backgrounds tab you can
-set background images for the room.
-
-
-
Adding instances
-
-At the right in the room design form you see the room. At the start it is empty, with
-a gray background.
-
-
-
-
-
-To add instances to the room, first select the objects tab if this one is not
-already visible. Next select the object you want to add by clicking on the button with
-the menu icon (or by clicking in the image area at the left). The image of the object
-appears at the left. (Note that when you changed the origin of the sprite
-there is a cross in the image. This indicates how the
-instances will be aligned with the grid.) Now click with your left mouse button in the
-room area at the right. An instance of the object appears. It will snap to the
-indicated grid. If you hold the <Alt> key while placing the instance it is not
-aligned to the grid. If you hold down the mouse button while dragging it over the
-room, you move the instance to the correct place. If you hold the <Shift> key
-while pressing and moving the mouse multiple instances are added. With the right mouse
-button you can remove instances. In this way you define the contents of the room.
-
-
-As you will notice, if you place an instance on top of another one, the original
-instance disappears. Normally this is what you want, but not always. This can be
-avoided by unchecking the box labeled Delete underlying at the left.
-
-
-If you want to change the position of an instance, hold the <Ctrl> key and click
-with the left mouse button on the instance and hold down the button. You can now drag
-it to a new position. (Use <Alt> for precise positioning.)
-
-
-If you hold the <Ctrl> key while clicking with the right mouse button on an
-instance, a menu appears. Here you can delete the object, type in a precise position
-for the instance, or move the bottommost instance at the position to the top or send
-the topmost instance to the bottom.
-
-
-
-
Room setting
-
-Each room has a number of settings that you can change by clicking on the settings tab.
-
-
-
-
-
-Each room has a name. Best give it a meaningful name. There also is a caption. This
-caption is displayed in the window caption when the game is running. You can set the
-width and height of the room (in pixels). Also you can set the speed of the game. This
-is the number of steps per second. The higher the speed, the smoother the motion is.
-But you will need a faster computer to run it.
-
-
-
-
Setting the background
-
-With the tab backgrounds you can set the background image for the room.
-Actually, you can specify multiple backgrounds. The tab page looks as follows:
-
-
-
-
-
-At the top you will see the background color. You can click on it to change it. The
-background color is only useful if you don't use a background image that covers the
-whole room. Otherwise, best uncheck the box labeled Draw background color
-because this will be a waste of time.
-
-
-At the top you see a list of 8 backgrounds. You can define each of them but most of
-the time you will need just one or two. To define a background, first select it in the
-list. Next check the box labeled Visible when room starts otherwise you won't
-see it. The name of the background will become bold when it is defined. Now indicate a
-background image in the menu. There are a number of settings you can change. First of
-all you can indicate whether the background image should tile the room horizontally
-and/or vertically. You can also indicate the position of the background in the room
-(this will also influence the tiling). A different option is to stretch the
-background. The background will then be scaled so that it fills the entire room.
-The aspect ration of the image will not be maintained. Finally
-you can make the background scrolling by giving it a horizontal or vertical speed
-(pixels per step). Better not use scrolling with a stretched background. The result
-will be a bit jaggy.
-
-
-There is one more checkbox labeled Foreground image. When you check this box,
-the background is actually a foreground, which is drawn on top of everything else
-rather than behind it. Clearly such an image should be partially transparent to be of
-any use.
-

Distributing your game
-
-With the information in the preceding chapters you can create your games.
-When your game is finished you obviously want other people to play it. You can of course
-give them the .gmk file that you created and let them use Game Maker to play it
-but this is normally not what you want. First of all, you don't want others to be able
-to change the game, and secondly you also want people to play the game even if they do not have
-Game Maker. So you would like to create a stand-alone executable of your game.
-
-
-Creating stand-alone executables is very easy in Game Maker. In the File menu
-you select the item Create Executable.
-You will be asked for the name of the executable that should contain the game.
-Indicate a name, press OK and you have your stand-alone game that
-you can give to anyone you like. You can change the icon for the
-stand-alone game in the Global Game Settings. See Part 3
-for details.
-
-
-Once you have created a stand-alone executable in the way described above you can give this
-file to other people or place it on your website to download.
-You are free to distribute the games you create with Game Maker
-in any way you like. You can even sell them. This of course assumes that the sprites,
-images, and sounds you use can be distributed or sold as well.
-See the enclosed license agreement for more information.
-
-
-It is normally useful to zip your executable, together with some readme information.
-In Windows XP and later this can be done directly through the right mouse button menu, and there
-are many free zip utilities available on the web. Alternatively you can create an
-installer for your game. Again, a large number of free installation creation programs
-are available on the web.
-
-
-If you want your game to be played by many more people we recommend you to upload it to the
-YoYo Games website and press on the Share button at the top.

Advanced mode
-
-Up to now we have only considered the simple features of Game Maker. But there are a lot more
-possibilities. To be able to use these you must run Game Maker in advanced mode.
-This is easy to change. In the File menu, click on the menu item Advanced mode.
-(To fully see the effects you should restart Game Maker or at least save your
-game and load it anew.)
-
-
-When you start Game Maker in advanced mode, the following form is shown:
-
-
-
-
-
-It contains all that was there in simple mode, but there are a number
-of additional resources, buttons, and menu items. Also, as we will see
-in the chapters that follow, the different resources have additional options.
-Here we will discuss the additional menu items.
-
-
-
File menu

-
Load last opened file on startup.
- If checked when you start Game Maker the most recently opened file
- is opened automatically.
-
Keep backup copies of files.
- If checked the program saves a backup copy of your game with
- the extension gb0-gb9. You can open these games in Game Maker.
- You are strongly advised to use at least one backup copy for your work!
-
Maximum number of backups.
- Here you can indicate how many (1-9) different backup copies
- should be remembered by the program.
-
Show progress while loading and saving files.
- If checked, when load or save a file a progress indicator is shown.
-
At startup check for, and remove old temporary files.
- Game Maker and games created with it, create temporary files.
- Normally these are automatically removed but sometimes, for example
- when games crash, they are left behind. If this option is checked,
- Game Maker checks whether such files exist and removes them at startup.
-
Don't show the website in the main window.
- When checked the image and link to the website on the main window are not shown.
-
Hide the designer and wait while the game is running.
- When checked the game making program is hidden while you are testing a game.
-
Run games in secure mode.
- If checked, any game created with Game Maker that runs on your
- machine will not be allowed to execute external programs or change
- or delete files at a place different from the game location.
- (This is a safeguard against Trojan horses although success is not
- guaranteed.) Checking this means that games that utilizes external
- files etc. won't be running correctly.
- The setting only works while Game Maker is running.
- So if you run the game independently of Game Maker, for
- example as an executable stand-alone, it is NOT
- run in secure mode.
-
Show news on startup. Whether to show the Game Maker news
- once a day when the program is started. (Cannot be changed in the Lite Edition.)
-
Show news in default brower. Whether to show the Game Maker news
- in your default Internet browser, rather than in the program itself.
- (Cannot be changed in the Lite Edition.)
-
-
-
Forms tab
-
-
-
-
-
-
-
Show the origin in the sprite image.
- If checked, in the sprite properties form, in the sprite image, the origin
- for the sprite is indicated.
-
In object properties, show hints for actions.
- If checked, in the object properties form, when you hold your mouse
- over one of the actions, a description is shown.
-
When closing, remove instances outside the room.
- If checked, the program warns you when there are instances or tiles
- outside a room and lets you remove them.
-
Remember room settings when closing the form.
- If checked, a number of room settings, like whether to show the grid,
- whether to delete underlying objects, etc. are remembered when you
- edit the same room later.
-
-
-
Scripts and code tab
-
-
-
-
-
-
-These settings relate to the built-in script and code editor.
-Most of these settings are explained in detail in the page on Scripts.
-Here we just give a short overview:
-
-
-
Group undo operations When grouped multiple actions (like typing a whole line) becomes
- one operation for undo.
-
Number of undo You can change this number but in general this should be fine.
-
Automatic indentation When set Enter and Backspace keys cleverly deal with indents.
-
Indent amount How much to indent with each tab.
-
Smart tabs When set tabs go to the position below the first non-empty space in the previous line.
-
Allow cursor beyond end of line When checked you can place the cursor at any position in the editor screen,
- also beyond the end of line. If unchecked this is not possible. This also changes the behavior
- of the left and right arrow keys.
-
Show auto-completion options When set help is given on which functions and variables start with the
- letters you are typing.
-
Dealy (msec) The delay in milliseconds before the help is shown. Set e.g. to 0 for immediate.
-
Show function argument help When set, when typing function arguments, in the statusbar help about
- this is provided.
-
Show find string When set, whenever typing in a find string, all locations are shown in the code.
-
Show line numbers Whether the editor should display the line numbers.
-
Show matching brackets Whether the editor should indicate matching open en close brackets.
-
Show code snippets with F2 When set, pressing F2 will bring up a number of useful code snippets.
-
Check code while typing When set the code is constantly checked and errors reported.
-
Use color coding Whether to use color coding in the editor.
-
Colors Here you can set the colors used for color coding. You can also reset the default colors.
-
Font Here you can select the font for the editor. Note that only fixed pitch fonts are shown. Also
- note that only the font and the size are used.
-
-
-
Editors
-
-
-
-
-
-
-Here you can choose whether to use the built-in code editor (highly recommended) or
-an external editor. In the case of an external editor, the script text is saved as
-a .txt file and the editor is called with this file as an argument. After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
-Also you can choose whether to use the built-in image editor (highly recommended) or
-an external editor. In the case of an external editor, the image is saved as
-a .png file and the editor is called with this file as an argument. After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
-Finally you can indicate the different external editors for the sound files you want to use.
-Game Maker does not contain internal sound editors. There are three possible editors
-handling .wav, .mid and .mp3 files. In the case of an external editor, the sound is saved as
-a .wav, .mid, or .mp3 file and the corresponding editor is called with this file as an argument.
-After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
Other Settings
-
-
-It is also possible to change the location of the temp files that Game Maker creates
-to e.g. store the game that is tested. This location cannot be changed from the Preferences but
-is changes by creating a file tempdir.txt in the folder where Game Maker is located.
-In this file there should be one line containing the location of the folder in which the temp files
-are creates, for example C:\GMTEMP. Note that the name must include the complete path
-and should not end with a backslash. Each time Game Maker is run a unique temporary folder is
-created within this location. So things will work out fine, even when multiple instances of Game Maker
-use the same location. (Note that the games themselves also create a temp folder for their files. Again,
-this can be changed by creating a file tempdir.txt and placing it in the folder where the game
-executable is located.)
-
-
-Secondly, it is possible to change the image Game Maker is using for the background of its main form.
-To this end place an image file back.bmp in the folder where Game Maker is located.

More about sprites
-
-When running Game Maker in advanced mode the
-A number of advanced options exist. When you open the sprite form it will look as follows:
-
-
-
-
-
-A new button Save Sprite has appeared. With this button you can save the sprite
-in a proprietary format. This format will not only store the image(s) of the sprite
-but also other settings, such as collision settings and the origin. The file will have
-the extension .gmspr. Game Maker can load such files but also the games can
-load them.
-
-
-At the bottom-left, you can indicate the origin of the sprite. This is the point in the
-sprite that corresponds with its position in the room. When you set an instance at a
-particular position, the origin of the sprite is placed there. Default it
-is the top left corner of the sprite but it is sometimes more convenient
-to use the center (by clicking the Center button)
-or some other important point. You can even choose an
-origin outside the sprite. You can also set the origin by clicking in the
-sprite image. The origin will be shown with a cross.
-
-
-Most important are the options related to collision checking. Whenever two instances
-meet a collision event is generated. Collisions are checked in the following way.
-Each sprite has a mask. Default this corresponds to all pixels that are not fully transparent.
-When two pixels in the masks of the two sprites overlap, a collision is reported.
-
-
-Sometimes you don't want precise collision checking. In this case, uncheck the
-box Precise collision checking. Now the bounding box is used as the mask.
-
-
-When the sprites has multiple subimages, default there is just a single mask that
-combines the masks of all subimages. Normally this is what you want but in certain
-situations you might want each subimage to have its own mask. In this case check
-the box Separate collision masks.
-
-
Collision Masks
-
-
-If you want even more control over
-the collision masks, press the button Modify Mask. The following window
-will show:
-
-
-
-
-
-At the left top there is again the information about the sprite image. You can
-show the different subimages. Also you can indicate here whether to show the
-collision mask (default on). In this case, in the images at the right the mask
-is shown in dark. You can also zoom in and out to get a better view.
-
-
-
-To the right of this you can change the bounding box. Only pixels inside this bounding box are used for
-the mask. Default the bounding box is automatically computed, taking the alpha tolerance
-into account, separate for each subimage, when using separate collision masks. You can
-also set it to the full image or you can set it to manual. In the latter case you can specify
-the bounding box yourself. When set to manual you can also draw the bounding box with the
-left mouse button in the image, or you can move it with the right mouse button. (Note though
-that the mask is shown while drawing, not the bounding box!)
-
-
-
-Below this you can indicate the shape of the mask. Default is precise, pixel-wise
-collision checking, but you can select here also to use the bounding rectangle, a disk (or
-ellipse) inside it, or a diamond shape. Rectangles or disks are is many cases better
-representations of the shape. (Note that the choice has no effect on speed!)
-
-
-
-Finally, at the left bottom you can (again) indicate whether or not there should be separate
-collision masks for all subimages. (Note that if you set the bounding box manual,
-a single bounding box will be used for all subimages, regardless of this setting.)
-You can also indicate the tolerance with respect to the transparency. With
-a higher tolerance also pixels that are partially transparent are left outside
-the mask. This influences both the bounding box (when not set to manual) and the
-mask for precise collision checking.

-
-It is important to carefully decide on the collision mask you use for your sprites.
-Although precise collision checking might seem the most logical option, in many
-cases game play is improved by using bounding boxes or disks, or masks that are a
-bit smaller than the actual sprites. If you want even further control over the mask,
-note that for objects you can specify a different sprite to use as mask. In this way
-you can make the collision mask completely independent of the image.
-
-
-
-Once you are done, press OK. If the mask was modified, the word Modified will
-show in the sprite form such that you are reminded that you changed some settings here.

Editing Sprites
-
-
-Game Maker has extensive possibilities to create and change your own sprites.
-Information about this can be found in the following pages:
-
-
-
-
-Up to now we loaded our sprites from files. It is though also possible to
-create and in particular modify them within Game Maker. To do this,
-open the sprite property window by double clicking on one of your sprites
-(or by creating a new one). Now press the button labeled Edit Sprite.
-A new form will appear showing all the subimages that make up the sprite.
-
-
-The sprite editor form will look as follows:
-
-
-
-
-
-At the right you see the different images that make up the sprite. Note that
-in Game Maker all subimages of a sprite must have the same size. At
-the left an animation of the sprite plays. (If you don't see the animation,
-check the box labeled Show Preview.) Below the preview you can change
-the speed of the animation and the background color. Also you can select one
-of the backgrounds in your game and whether it must be streched. In this way you can
-get an idea of what the animation will look like in the game. (Note that
-this speed is only for preview. The speed of the animation during the
-game depends on the room speed.)
-
-
-The sprite editor contains many commands to create and change the sprite.
-These are all given through the menus. (For some there are buttons on the
-toolbar.) Some commands work on individual images. They require that you
-first select a subimage with the mouse.
-
-
-
File menu
-
-
-The file menu contains a number of commands related to loading and saving sprites.
-
-
-
New.
- Creates a new, empty sprite. You must indicate the size of the sprite.
- (Remember, all images in a sprite must have the same size.)
-
Create from File.
- Creates the sprite from a file. Many file types can be used.
- They all create a sprite consisting of a single image, except
- for animated GIF files that are split into the subimages and strips
- that have an name ending with _stripXX. When selecting a file
- you can indicate whether the image should be opaque, whether to
- remove the background, and whether to smooth the edge. You can select
- multiple images which will then all be loaded. They should preferably
- have the same size, otherwise, their canvas sizes will be adapted.
-
Add from File.
- Adds an image (or multiple images) from a file to the current sprite. If the
- images do not have the same size you can choose where to place them
- or to stretch them. You can select multiple images which will then
- all be loaded. They must preferably have the same size.
-
Save as PNG File.
- Saves the sprite as a strip in a PNG file. When the sprite has multiple
- subimages the text _stripXX with XX the number of subimages is automatically
- appended.
-
Create from Strip.
- Allows you to create a sprite from a strip. See the next section for more information.
-
Add from Strip.
- Use this to add images from a strip. See the next section.
-
Close Saving Changes.
- Closes the form, saving the changes made to the sprite. If you don't
- want to save the changes, click on the close button of the form.
-
-
-
-
Edit menu
-
-
-The edit menu contains the following commands:
-
-
-
Undo.
- Undo the last change. The last 16 changes can be undone.
-
Redo.
- Redo the last undone change.
-
Cut.
- Cut the currently selected subimage to the clipboard. You can edit or use the
- subimage in a different program this way. However, the transparency information
- might be lost.
-
Copy.
- Copy the currently selected subimage to the clipboard.
-
Paste.
- Paste the image on the clipboard as a new subimage. When it has not the correct
- size you should indicate how to change this. When the image came from a different
- program, transparency information might be lost.
-
Erase.
- Erase the current, or all images to a particular color. A form open in which you can
- select the color and the opacity (alpha) value. A preview of the result it shown. You
- can indicate whether to erase all images or only the current one.
-
Delete.
- Delete the currently selected subimage.
-
Move Left.
- Move the currently selected subimage one position to the left in the sequence.
-
Move Right.
- Move the currently selected subimage one position to the right in the sequence.
-
Add Empty.
- Add a new empty subimage at the end of the sequence.
-
Insert Empty.
- Insert a new empty subimage before the currently selected subimage.
-
Edit.
- Edit the currently selected subimage using the built-in image editor.
-
Set Tranparency Background.
- Here you can indicate how the transparent area of the sprites should be shown in the
- sprite editor. You can either use the (default) block pattern, or a color that you can change
- by clicking on the color box.
-
-
-
-
Transform menu
-
-
-In the transform menu you can perform a number of transformations on the images. For most of them
-you can choose whether to apply them only to the current sub image or to all images.
-
-
-
Shift.
- Here you can shift the image(s) an indicated amount horizontally and vertically.
-
Mirror/Flip.
- Mirror the image(s) horizontally and/or flip them vertically.
-
Rotate.
- You can rotate the image(s) 90, 180 or 270 degrees, or an arbitrary
- amount.
-
Scale.
- This command scales the image(s) (but not the image size!). You can indicate
- the scale factor and whether to scale horizontally and/or vertically.
-
Skew.
- This command skews the image(s) horizontally and/or vertically with a given amount.
-
Resize Canvas.
- Here you can change the size of the canvas. You can also indicate where the
- images are placed on the new canvas.
-
Stretch.
- Here you can stretch the images into a new size. You can indicate
- the scale factor and the quality.
-
Crop.
- This makes the images as small as possible. This is very useful because the
- larger the images, the more video memory Game Maker will use.
- You can indicate the size of a transparent border around the images.
- If you provide a negative value, the outside of the images will be cut off.
-
-
-
-
Images menu
-
-
-In the images menu you can perform a number of operation on the images. Some of these
-are only available in the Pro Edition.
-
-
-
Cycle Left.
- Cycles all images one place to the left. This effectively starts
- the animation at a different point.
-
Cycle Right.
- Cycles all images one place to the right.
-
Black and White.
- Makes the image(s) black and white (that is, grayscale).
-
Colorize.
- Here you can change the color (hue) of the images.
- Use the slider to pick the new hue. When you indicate to shift the
- hue the colors are shifted over the amount indicated giving rather interesting
- effects.
-
Colorize Partial.
- Here you can change the color (hue) of part of the images. You can
- select the old hue and a tolerance around it and then indicate the new
- hue with which to replace this range of colors. This can be used
- for instance to change only the color of the shirts of players. You can pick the old
- hue also by clicking in the left image.
-
Intensity.
- Here you can change the intensity by providing values for the color
- saturation and the value of the new images.
-
Invert.
- Inverts the colors in the images.
-
Make Opaque.
- Remove all transparency information from the images, making them opaque.
-
Erase a Color.
- You can select a color (either by clicking on the color box or by clicking in the left image.
- Also you specify a tolerance. All pixels with a color close the the selected color will be
- made transparent.
-
Smooth Edges.
- Smooth the edges around the opaque part of the image(s) somewhat to make them look nicer.
- (A stronger effect can be created by using Blur but only blurring the transparency; see below.
-
Opacity.
- Here you can change the opacity (transparency) for the whole image. You can either set it
- relative to the current opacity or absolute. (Fully transparent pixels always stay fully
- transparent.)
-
Set Alpha from File.
- You select an image. The lightness of the pixels of that image will be used as transparency value.
- Black pixels will lead to completely transparent pixels, while white pixels will lead to opaque
- pixels. When the image does not have the correct size it will be stretched.
- Only available in the Pro Edition.
-
Fade.
- Here you specify a color and an amount. The pixels in the image(s)
- are now faded towards this color with the given amount.
-
Blur.
- By blurring the images the colors are mixed a bit, making it more vague. You can select a
- small, medium, or large blur. Also you can select whether to blur the color values and/or
- the transparency values. Only blurring the transparency values is a nice way to smooth the
- boundary of the images.
-
Sharpen.
- This is sort of the reverse of blurring. The image will be made more sharp, enhancing the
- edges. You can do a subtle sharpening or a strong sharpening. The special sharpening puts
- additional empasis on the edges, leading to a funny effect. You can sharpen the color
- values and/or the transparency values.
-
Outline.
- Create an outline around the image. You are asked for the color and a thickness of the outline.
- You can also indicate to place the outline inside the image. You can indicate whether to
- remove the image itself, just keeping the outline, and whether to smooth the outline.
- Only available in the Pro Edition.
-
Shadow.
- Create a shadow behind the image. (This will only work when the image is partially transparent.)
- You indicate the color of the shadow and the opacity. Also you indicate the relative position
- of the shadow. Finally you can indicate whether it should be a soft or a hard shadow.
- Only available in the Pro Edition.
-
Glow.
- Create a colored glow around the image.
- You indicate the color of the glow, the opacity and the thickness.
- You can also indicate to place the glow inside the image.
- Only available in the Pro Edition.
-
Buttonize.
- Turn the image(s) into a button. You specify the color of the button and the opacity. Also you
- must indicate the thickness of the button boundary and whether it should be smooth or not.
- Only available in the Pro Edition.
-
Gradient Fill.
- Adds a gradient fill to the image(s). You specify the two colors of the fill, the opacity,
- and the kind of fill. Default the image is replace by the gradient although the transparency is
- maintained. By unchecking the Replace box the gradient is blended onto the image. By checking
- the Change Transparency box the alpha value of the original image is changed as well. You
- can create great effects. For example, make an image black-and-white and then blend a gradient
- on it. Only available in the Pro Edition.
-
-
-
-You will have to experiment with these commands to get the sprites you want.
-
-
-
Animation menu
-
-
-Under the animation menu you can create new animated sprites out of the current sprite.
-There are many options and you should experiment a bit with them to create the effects
-you want. Also don't forget that you can always save an animated sprite and later add it to
-the current one. Also you can always add some empty images and delete unwanted ones.
-We will briefly go through the different possibilities.
-
-
-
Set Length.
- Here you can change the length of your animation. The animation is
- repeated enough times to create the number of frames you indicate.
- (Normally you want this to be a multiple of the current number of frames.)
-
Stretch.
- This command also changes the length of the animation. But this time,
- frames are duplicated or removed to get the right number. So if you
- increase the number of frames the animation goes slower and if you
- decrease the number it goes faster.
-
Reverse.
- Well, as you could guess this reverses the animation. So it is played backwards.
-
Add Reverse.
- This time the reverse sequence is added, doubling the number of frames.
- This is very useful for making an object go left and right, change color
- and return, etc. You sometimes might want to remove the double first
- and middle frame that occur.
-
Translation Sequence.
- You can create an animation in which the image slightly translates in
- each step. You must provide the number of frames and the total amount
- to move horizontally and vertically.
-
Rotation Sequence.
- Creates an animation in which the image rotates. You can either choose
- clockwise or counterclockwise rotation. Specify the number of frames and
- the total angle in degrees (360 is a complete turn). (You might need to
- resize the canvas first to make sure the total image remains visible
- during the rotation.)
-
Colorize.
- Creates an animation that turns the image into a particular color.
-
Fade to color.
- Creates an animation that fades the image to a particular color.
-
Disappear.
- Makes the image disappear by making it more transparent in each step.
-
Shrink.
- Shrinks the image to nothing. You can indicate the direction.
-
Grow.
- Grows the image from nothing.
-
Flatten.
- Flattens the image to nothing in a given direction.
-
Raise.
- Raises the image from a given direction.
-
Overlay.
- Overlays the animation with another sprite or image in a file. You indicate the file
- and the image(s) from that file are then placed on top of the current animation.
- When the image from the file has a different size it is stretched.
-
Morph.
- Morphs the animation to an animation or image from a file. Note that
- morphing works best if the two animations cover the same area of the
- image. Otherwise, halfway certain pixels disappear and others suddenly appear.
-
-
-
-In particular the last two commands are very powerful. For example, to blow
-up an object, add a number of copies and then a number of empty frames.
-Then overlay it with an explosion animation. (Make sure the numbers of images
-match.) Alternatively, morph it to the explosion. With some practice you
-can make great sprites.

Strips
-
-
-As indicated above, sprites are normally either stored as animated gif files or
-as strips in PNG files, in which all subimages are placed next to each other. In the
-second case the file name should end with _stripXX where XX indicates the number
-of subimages.
-
-
-However, sometimes sprites are part of a larger bitmap in which the sub images can
-be stored next to each other or below each other and maybe there are separating lines
-between them. Such a strip cannot be read automatically as Game Maker will not
-know the size and position of the subimage. For example, the following piece of a strip file
-contains four different animations.
-
-
-
-
-
-If you want to pick a certain animation out of such a file you must indicate where the
-images are. To this end you can choose
-Create from Strip or Add from Strip from the File menu
-in the sprite editor.
-After indicating the appropriate strip image file, the following form will show:
-
-
-
-
-
-At the right you see (part of) the strip image you selected. At the left you
-can specify a number of parameters that specify which subimages you are
-interested in. Note that one or more rectangles in the image indicate the
-images you are selecting. The following parameters can be specified:
-
-
-
-
Number of images.
- This is the number of sub images you want to take from the strip.
-
Images per row.
- How many images of the ones you want are there per row. For example,
- by setting this to 1 you will select a vertical sequence of images.
-
Image width.
- Width of the individual images.
-
Image height.
- Height of the individual images.
-
Horizontal cell offset.
- If you don't want to select the top-left images, you can set here
- how many images should be skipped horizontally.
-
Vertical cell offset.
- Here you indicate how many images to skip vertically.
-
Horizontal pixel offset.
- Sometimes there is some additional space at the left top.
- Here you indicate this amount (in pixels). You can also use the mouse to indicate
- the place where the first image should start
-
Vertical pixel offset.
- Vertical amount of extra space.
-
Horizontal separation.
- In some strips there are lines or empty space between the images. Here
- you can indicate the horizontal amount to skip between the images (in pixels).
-
Vertical separation.
- Vertical amount to skip between the images.
-
-
-
-Once you selected the correct set of images, press OK to create your sprite.
-Please remember that you are only allowed to use images created by others when you
-have their permission or when they are freeware.

Editing individual images
-
-Game Maker has a built-in image editor that can be used to edit
-individual subimages of sprites and background images. To call the editor
-for a subimage of a sprite, select the subimage in the sprite editor
-and choose Edit Image from the Image menu (or double click on it).
-To edit a background, open the background properties for and press the button
-Edit Background.
-
-
-The built-in image editor is pretty powerful and especially suited for creating
-sprites and backgrounds for Game Maker. However, it does not have all
-the features of full-blown paint and drawing packages. The buitl-in editor
-is primarily meant for making changes to images, not for creating sprites and
-backgrounds from scratch. For this you probably want to use a separate paint
-program, save the images as PNG files, and load them into Game Maker.
-You can also set an external image editor in the preferences.
-
-
-When you start the image editor it will typically looks as follows:
-
-
-
-
-
-The form shows the image in the middle and a number of drawing tools at
-the left. Below there you can set certain properties of the drawing tools.
-These will change depending on the tool you select (see below). In the middle
-you see the current image. You can zoom in and out using the buttons on the
-toolbar. At the right there is information about the colors with which the draw.
-You can set a separate color for the left and the right mouse button. You can change
-these by clicking with the left or right mouse button in the color selector images.
-Also you can change them by clicking in the boxes at the top that repesent the colors.
-Below the colors you see the Opacity. This indicates how opaque or transparent the color is.
-When you set it to 255 the pixels your draw are fully opaque. When you set it to 0
-they are fully transparent. Normally when you draw partially transparent pixels they
-are blended with the current color. By setting the Color Mode to Replace, the pixels
-will be replaced with the new color. Finally at the bottom of the form there is a
-statusbar with some infomation about the current drawing tool, the position of the mouse,
-the size of the image, and the amount of memory it requires.
-
-
Drawing tools
-
-
-The following drawing tools are available (from left to right, top to bottom).
-
-
-
Paint.
- With this tool you can paint on the image. You can use the left or right mouse
- button to paint in the different colors. You can select the size of the pen.
- When holding <Shift> when starting to paint you only paint horizontal or
- vertical lines. When holding the <Ctrl> key you can select a new paint color.
-
Spray.
- With this tool you can spray on the image. Spray is like paint except that you use a
- brush that is partially transparent at the sides. You can use the left or right mouse
- button to paint in the different colors. You can select the size of the brush. You can
- also select the hardness of the brush. A soft brush will be more transparent near the sides.
- When holding <Shift> when starting to spray you only paint horizontal or
- vertical lines. When holding the <Ctrl> key you can select a new spray color.
-
Erase.
- With this tool you can erase part the image. It looks a lot like spray but you erase
- what is below the mouse. How much you erase depends on the the Opacity. For a value of
- 255 you erase completely. For a smaller value you only make the image a bit more
- transparent. You can set the hardness of the eraser.
- When holding <Shift> when starting to spray you only paint horizontal or
- vertical lines.
-
Color Picker.
- With this tool you can set the left or right mouse color to the color of a pixel in the
- image. Note that also the opacity value is set.
-
Line.
- With this tool you can can draw straight lines.
- When holding <Shift> you can draw horizontal, vertical, or diagonal lines.
- You can set the width of the line and whether is should have arrows. By selecting Anti-alias
- the line is drawn with partially transparent pixels on the side to make it more smooth.
-
Polygon.
- With this tool you can can draw a closed polygon. You click on the position of the first vertex.
- Next you can either drag the next vertex or click on the position of the next vertex. In this way
- you continue. You end the polygon with the <Esc> key.
- When holding <Shift> you can draw horizontal, vertical, or diagonal lines.
- You can set the width of the line and whether the polygon should be filled or not.
- By selecting Anti-alias
- the polygon is drawn with partially transparent pixels on the side to make it more smooth.
-
Rectangle.
- With this tool you can can draw a rectangle.
- When holding <Shift> you can draw a square.
- When holding <Ctrl> you draw the rectangle from the center.
- You can set the width of the line and whether the rectangle should be filled or not.
- By selecting Anti-alias
- the rectangle is drawn with partially transparent pixels on the side to make it more smooth.
-
Ellipse.
- With this tool you can can draw an ellipse.
- When holding <Shift> you can draw a circle.
- When holding <Ctrl> you draw the ellipse from the center.
- You can set the width of the line and whether the ellipse should be filled or not.
- By selecting Anti-alias
- the ellipse is drawn with partially transparent pixels on the side to make it more smooth.
-
Rounded Rectangle.
- With this tool you can can draw a rounded rectangle.
- When holding <Shift> you can draw a square.
- When holding <Ctrl> you draw the rounded rectangle from the center.
- You can set the width of the line and whether the rounded rectangle should be filled or not.
- By selecting Anti-alias
- the rounded rectangle is drawn with partially transparent pixels on the side to make it more smooth.
-
Select Region.
- With this tool you can can select a rectangular region. You can extend the current selection by
- holding the <Shift> key. Also you can remove parts by holding the <Ctrl> key.
- Once you made a selection you can pick it up with the mouse and drag it to a new position. When you
- use the right mouse button you make a copy. The selection can also be cut or copied to the
- clipboard. It can be deleted with the <Del> key. You can end the selection using the
- <Esc> key.
-
Select with Magic Wand.
- In this case you make the selection by clicking on a pixel. All connected pixels with the same
- color will be selected. You can indicate the tolerance in color valu with which to select pixels
- and whether only the color or also the transparency value should match. You can extend the current selection by
- holding the <Shift> key. Also you can remove parts by holding the <Ctrl> key. You can
- manipulate the selection as above.
-
Select by Spraying.
- In this case you make the selection by spraying with the mouse on the image. You can set the size
- of the selector. For the rest the selection can be treated as above. Different selection types
- can be combined.
-
Text.
- To add a text click on the image. A pop-up window appears in which you
- can enter the text. Use the # symbol to insert a newline. Once you press
- OK the text is put in the image, with a box around it. You can now move
- the text by pressing with the mouse in the box and dragging the text. You can change
- the text by clicking with the right mouse button in the box. You can set the Font of the text
- and how the different lines should be alligned.
-
Fill.
- Click on a pixel in the image and all connected pixels with the same color will be turned
- into the new pixel. You can set the tolerance with which the color should match. Also you can
- set whether to only match on the color value or also take the transparency value into account.
- Not that when the Color Mode is set to Blend the fill color is blended with the existing one. To
- replace it, set the Color Mode to Replace.
-
Change Color.
- Click on a pixel in the image and all pixels in the image with the same color will be turned
- into the new pixel. You can set the tolerance with which the color should match. Also you can
- set whether to only match on the color value or also take the transparency value into account.
- Not that when the Color Mode is set to Blend the new color is blended with the existing one. To
- replace it, set the Color Mode to Replace.
-
-
-
-
-
Menus
-
-A number of further commands is available through the menus. For some of these there is a corresponding
-button on the tool bar.
-
-
File menu
-
-
-
New.
- Creates a new, empty image. You must indicate the size of the image. (When the image is part of
- a sprite with multiple images you cannot set the size.)
- (Remember, all images in a sprite must have the same size.)
-
Open.
- Open an image from a file. This menu item is not available when the image is part of
- a sprite with multiple images.
-
Previous Image.
- Only available when the image is part of
- a sprite with multiple images. Saves the changes and opens the previous subimage.
-
Next Image.
- Only available when the image is part of
- a sprite with multiple images. Saves the changes and opens the next subimage.
-
Save as PNG File.
- Saves the image as a PNG file. No other file formats are supported.
-
Close Saving Changes.
- Closes the form, saving the changes made to the image. If you don't
- want to save the changes, click on the close button of the form.
-
-
-
Edit menu
-
-Here you find the usual commands to Undo the last change and Redo the last undo, to delete, cut, or
-copy the current selection to the clipboard, to paste the image on the clipboard as a selection
-in the image, and to select all. (Note that when using the clipboard, transparency information might
-be lost.) Two additional commands require a bit more explanation.
-
-
-
Erase to Left Color.
- This erases the image and replaces it by the left color (and opacity setting).
-
Paste from File.
- You can select an image from a file. This image is then pasted into the current image
- as a selection. You can then move that selection to the appropriate place.
-
-
-
View menu
-
-
-
Zoom Out.
- You can zoom out to see more of the image. You can also hold the <Ctrl> key
- and move the mouse scroll wheel to zoom in or out.
-
No Zoom.
- Sets the image back to the normal size.
-
Zoom In.
- You can zoom in to more precisely draw in an area of the image.
-
Toggle Grid.
- You can toggle the grid on or off. Note that the grid is only shown when you
- zoom in enough.
-
Grid Options.
- Here you can set the size of the grid and the color. You can indicate whether to use exclusive
- or when drawing the grid (might make it more visible) and whether the drawing should be snapped
- to the grid.
-
Show Preview.
- Show a preview of the image in the right bottom corner in the normal size. This is in particular
- useful when you are zooming in a lot to make small changes. If the image is larger than the preview
- are you can use the mouse to drag the part of the image you want to see. You can also double click
- on the preview image to open a separate preview window in which you can see the complete image.
-
Set Tranparency Background.
- Here you can indicate how the transparent area of the image should be shown in the
- sprite editor. You can either use the (default) block pattern, or a color that you can change
- by clicking on the color box.
-
-
-
Transform menu
-

More about sounds and music
-
-In advanced mode you have a lot more control over the sounds and
-pieces of music you add to your game. When you add a sound resource the
-following form will show:
-
-
-
-
-
-
-Besides the buttons to load, save, and play sounds there are a lot
-of settings now that will be discussed here.
-
-
-First of all you can indicate the kind of sound. Four kinds are possible.
-Normal sounds are in general used for sound effects in wave files (although
-they can be used for midi files as well). Multiple normal sounds can play
-at the same time. You can even play multiple copies of the same sound
-simultaneously. Background music is similar to normal sounds but only
-one can play at any moment. So once you start a new background sound, the
-currently playing one will be stopped. Midi files are default background
-music. 3D sound is sound for which you can apply 3D settings through
-special functions. You will only need these for advanced sound effects.
-
-
-Sound files are normally played through DirectX. This gives many possibilities
-but is limited to wave and midi files. If you want to play other files, like
-mp3 files, you should select the option to use the media player. This is much
-more limited though. No volume changes or effects can be used and only one piece
-can play at once.
-Note that midi files, when played through the media player may sound different
-from playing them as background or normal sounds. The reason is that the media
-player uses the hardware synthesizer (which is different on each machine) while
-otherwise a software version is used (which sounds the same on all machines).
-Preferably don't use mp3 files in you games.
-They need to be decompressed which takes
-processing time and might slow down the game. The fact that the file size is
-smaller does not mean that they use less memory. Also, not all machines
-support them. So your game might not run on all machines.
-
-
-Secondly, you can indicate some sound effects, like chorus or echo (only in the Pro Edition
-of Game Maker!) You can select any combination. You can immediately
-listen to the results. (When using GML code you can even change the parameters
-of these effects.)
-
-
-Also you can indicate the default volume of the sound and whether to
-pan it to the left or the right speaker.
-
-
-For all sounds you can indicate whether they should be preloaded or not.
-When a sound is played it must be loaded into audio memory. If you preload
-the sound this is done at the start of the game, making it immediately
-available for playback. When not, it is loaded the first time it is used.
-This will save memory but might give a small delay the first time the sound
-is used.
-
-
-Game Maker does not have a built-in sound editor. But in the
-preferences you can indicate external editors that you want to use for
-editing sounds. If you selected these you can press the button labeled
-Edit Sound to edit the current sound. (The Game Maker window will
-be hidden while you edit the sound and returns when you close the sound
-editor.)

More about backgrounds
-
-In advanced more there are a number of additional options for background.
-First of all, a new button Save Background has appeared. With this
-button you can save the background in a proprietary format. This will not only
-store the image itself but also for example information about the tiles (see below).
-These files will have the extension .gmbck. You can load them in Game Maker
-and while running a game.
-
-Also you can also change a background or create your own backgrounds by pressing the
-button labeled Edit Background. A built-in image editor opens that has many
-features. Please realize that this is not a full-blown program and if you require
-more advanced editing tools you might want to use a separate drawing program.
-For more information on how to use the image editor see the section on
-Editing images.
-
-
-Sometimes you want to use a background as a set of tiles, that is, a collection
-of smaller images in one big image. When create the rooms you can then add these
-subimages at different places in the room. This is very useful for creating
-nice looking levels. To use a background as a tile set, check the box labelled
-Use as tile set. The form now changes to look as follows:
-
-
-
-
-
-You can indicate a number of settings for the tile set. In particular you can
-indicate the width and height of each tile. (Only one size can be given, so
-better make sure that all tiles in the set have the same size. If you have
-different sizes, create two or more tile sets.) You can also indicate an
-offset where the top leftmost tile starts. Finally, a
-separation between the tiles (this is normally 0 or 1) can be indicated.
-For more information on using tiles, see the section on
-Adding Tiles when creating rooms.
-
-
-A word of warning is required here. When you put separating borders between the
-sprites and use interpolation between pixels (see the global game settings) this
-can result in cracks between the tiles. Better make sure the pixels around the
-tiles actually match with the pixels just inside the tiles to avoid this. You can
-easily achieve this by editing the background and changing the color of such pixels.

More about objects
-
-When you create an object in advanced mode, you can change some more
-advanced settings.
-
-
Depth
-
-First of all, you can set the Depth of the instances of the object.
-When the instances are drawn on the screen they are drawn in order of depth.
-Instances with the largest depth are drawn first. Instances with the
-smallest depth are drawn last. When instances have the same depth, they are
-drawn in the order in which they were created. If you want to guarantee that
-an object lies in front of the others give it a negative depth. If you want
-to make sure it lies below other instances, give it a large positive depth.
-You can also change the depth of an instance during the game using the
-variable called depth.
-
-
-
Persistent objects
-
-Secondly, you can make an object persistent. A persistent object will
-continue existing when you move from one room to the next. It only
-disappears when you explicitly destroy it. So you only need to put an
-instance of the object in the first room and then it will remain available
-in all rooms. This is great when you have a main character that moves
-from room to room. Using persistent objects is a powerful mechanism but also
-one that easily leads to errors.
-
-
Parents
-
-Every object can have a parent object. When an object has a parent, it
-inherits the behavior of the parent. Stated differently, the object is a sort
-of special case of the parent object. For example, if you have 4 different
-balls, named ball1, ball2, ball3 and ball4, which all behave the same but
-have a different sprite, you can make ball1 the parent of the other three.
-Now you only need to specify events for ball1. The others will inherit the
-events and behave exactly the same way. Also, when you apply actions to
-instances of the parent object they will also be applied to the children.
-So, for example, if you destroy all ball1 instances the ball2, ball3,
-and ball4 instances will also be destroyed. This saves a lot of work.
-
-
-Often, objects should behave almost identically but there will be
-some small differences. For example, one monster might move up and down and
-the other left and right. For the rest they have exactly the same behavior.
-In this case almost all events should have the same actions but one or two
-might be different. Again we can make one object the parent of the other.
-But in this case we also define certain events for the child object. These
-events "override" the parent events. So whenever an event for the
-child object contains actions, these are executed instead of the event of
-the parent. If you also want to execute the parent event you can call the
-so-called "inherited" event using the appropriate action.
-
-
-It is actually good practice in such cases to create one base object.
-This base object contains all the default behavior
-but is never used in the game. All actual objects have this base object as parent.
-Parent objects can again have parents, and so on. (Obviously you are not
-allowed to create cycles.) In this way you can create an object hierarchy.
-This is extremely useful to keep your game structured and you are strongly
-advised to learn to use this mechanism.
-
-
-There is also a second use of the parent object. It also inherits the
-collision behavior for other objects. Let us explain this with an example.
-Assume you have four different floor objects. When a ball hits the floor it
-must change direction. This has to be specified in the collision event of
-the ball with the floor. Because there are four different floors we need to
-put the code on four different collision events of the ball. But when you
-make one base floor object and make this one the parent of the four actual
-floor objects, you only need to specify the collision event with this base
-floor. The other collisions will perform the same event. Again, this saves a
-lot of copying.
-
-
-As indicated, wherever you use an object, this also implies the descendants.
-This happens when, in an action, you indicate that the action must be
-applied to instances of a certain object. It also happens when you use the
-with() statement in code (see below). And it works when you call
-functions like instance_position, instance_number, etc.
-Finally, it works when you refer to variables in other objects. In the
-example above when you set ball1.speed to 10 this also applies to
-ball2, ball3 and ball4.
-
-
Masks
-
-When two instances collide a collision event occurs. To decide whether two
-instances intersect, the sprites are used. This is fine in most cases, but
-sometimes you want to base collisions on a different shape. For example, if
-you make an isometric game, objects typically have a height (to give them a
-3D view). But for collisions you only want to use the ground part of the
-sprite. This can be achieved by creating a separate sprite that is used as
-collision mask for the object.
-
-
Information
-
-The button Show Information gives an overview of all information for
-the object that can also be printed. This is particularly useful when you
-loose overview of all your actions and events.

More actions

-In advanced mode there are a number of additional actions available which will be described here.
-
-
-
-
-
-
-Information on the different additional actions can be found in the
-following pages:
-
-
-
-Some additional move actions are available in advanced mode. The following actions are added:
-
-
- Set Path
-With this action you can specify that the instance should follow a particular path.
-You indicate the path that must be followed and the speed in pixels per step.
-When the speed is positive the instance starts at the beginning of the path.
-If it is negative it starts at the end. Next you specify the end behavior,
-that is, what should happen when the end of the path is reached. You can
-choose to stop the motion, restart from the beginning, restart from the current
-position (which is the same when the path is closed), or reverse the motion.
-Finally you can indicate that the path must be seen as absolute, that is, the
-position will be as indicated in the path (this is useful when you have designed
-the path at a particular place in the room) or relative, in which case the start
-point of the path is placed at the current location of the instance (end point
-when speed is negative). See the chapter on paths for more information.
-
-
- End Path
-Use this action to stop the path for the instance.
-
-
- Path Position
-With this action you can change the current position of the instance in the path.
-This must be a value between 0 and 1 (0=beginning, 1=end).
-
-
- Path Speed
-With this action you can change the speed of the instance on the path.
-A negative speed moves the instance backwards along the path. Set it to 0 to
-temporarily stop the motion along the path.
-
-
- Step Towards
-This action should be placed in the step event to let the instance take a step
-towards a particular position. When the instance is already at the position it
-will not move any further. You specify the position to move to, the speed with
-which to move, that is, the size of the step, and whether the motion should stop
-when hitting a solid instance or when hitting any instance.
-
-
- Step Avoiding
-This is a very powerful motion action. It should be placed in the step event.
-Like the previous action it lets the instance take a step towards a particular
-position. But in this case it tries to avoid obstacles. When the instance would
-run into a solid instance (or any instance) it will change the direction of
-motion to try to avoid the instance and move around it. The approach is not
-guaranteed to work but in most easy cases it will effectively move the instance
-towards the goal. For more complicated cases, there are motion planning functions.
-You specify the position to move to, the speed with which to move, that is, the
-size of the step, and whether the motion should avoid solid instances or any instance.

-Some additional main actions are available in advanced mode. The following actions are added:
-
-
- Set Time Line
-With this action you set the particular
-time line for an instance of an object. You indicate the time line and the
-starting position within the time line (0 is the beginning). Also you indicate
-whether the time line should start immediately and whether it should loop at the end.
-
-
- Time Line Position
-With this action you can change the position
-in the current time line (either absolute or relative). This can be used to skip
-certain parts of the time line or to repeat certain parts.
-
-
- Time Line Speed
-With this action you can change the speed of the time line (either absolute or relative).
-A speed of 1 is the normal speed. When you e.g. set it to 2 the actions will happen twice
-as fast and when you set it to 0.5 twice as slow. You can also set a negative speed, in which
-case the time line is played backwards.
-
-
- Start Time Line
-This action starts the time line from its current position (if it is paused or stopped).
-
-
- Pause Time Line
-This action pauses the time line. Use the start action to let it continue.
-
-
- Stop Time Line
-This action stops the time line and sets the position back to 0.
-
-
- Splash Text
-With this action you can show a text file. This can either be a .txt
-file or a .rtf (Rich Text Format) file (no images or embedded objects
-are shown though). You specify the file name. Make sure
-the file exists. You should either distribute it with the game or
-include it in the game through Include Files in the Resources menu.
-(Note that no scrollbar will be shown nor is
-there another way to scroll the text. So the text must fit the window.)
-This action is only available in the Pro Edition.
-
-
- Splash Image
-With this action you can show an image file. Most common image
-file types are supported. You specify the file name. Make sure
-the file exists. You should either distribute it with the game or
-include it in the game through Include Files in the Resources menu.
-You can e.g. use this to create a series of images as help for your
-game. Not including the images in the game itself will reduce game
-size and improve game loading time.
-This action is only available in the Pro Edition.
-
-
- Splash Webpage
-With this action you can show a webpage. You provide the url and
-whether it should be shown in the game window or in the default web browser.
-The url can be the address of a website, for example
-http://www.yoyogames.com) or can be the file name for a local html file.
-Note however that you must provide the full path for this to work (which is not the
-case for the other splash actions). So you best use as url
-something like "" + working_directory + "\index.html".
-(The first two quotes are required to indicate this is an expression
-rather than a string.) You should either distribute the file with the game or
-include it in the game through Include Files in the Resources menu.
-You can e.g. use this to create fancy help pages for your game.
-This action is only available in the Pro Edition.
-
-
- Splash Video
-With this action you can show a video/movie file. You specify the file
-name and whether is must be looped. Make sure
-the video file exists. You should either distribute it with the game or
-include it in the game through Include Files in the Resources menu.
-This action is only available in the Pro Edition.
-
-
- Splash Settings
-With this action you can change certain settings for the splash screens that
-you display with the previous actions. You can provide the caption for the
-help window (only when it is shown in a separate normal window), you can indicate
-where the splash screens must be shown (inside the game window, in a normal
-window, or full screen), you can indicate whether a close button must be shown
-in the top right corner of the splash screen and whether pressing the escape
-key or clicking with a mouse in the splash screen will close the splash screen.
-(For web pages clicking with the mouse will not work nor will the escape key
-work unless the close button is shown.)
-This action is only available in the Pro Edition.
-
-
- Replace Sprite
-This action can be used to replace a sprite from the contents of a file.
-You indicate the sprite you want to replace, the filename
-and the number of subimages in the sprite.
-Many different images file formats are supported, e.g. .bmp, .jpg, .tif, and .gif.
-For a gif file the number of subimages is automatically decided based on the
-number of subimages in the gif file. Other settings for the sprite, e.g.
-whether it is transparent or not, are not changed. You can use this action
-to avoid storing all sprites in the program itself. For example, at the beginning of a
-level you can replace sprites by the actual character sprites you want
-to use. DON'T change a sprite that is at that moment being used in an instance in
-the room. This might give unwanted effects with collisions.
-This action is only available in the Pro Edition.
-
-
- Replace Sound
-With this action you can replace a sound by the contents of a file (.wav, .mid, or .mp3).
-You specify the sound and the filename. This avoids having to store all the sounds in the
-game itself. For example, you can use different pieces of background music and pick the
-one you want to play. DON'T change a sound while it is playing.
-This action is only available in the Pro Edition.
-
-
- Replace Background
-With this action you can replace a background by the contents of a file.
-Many different images file formats are supported, e.g. .bmp, .jpg, .tif, and .gif.
-You specify the background and the filename. This avoids having to store all the backgrounds
-in the game itself. DON'T change a background that is visible.

Particle actions
-
-A set of action dealing with particles is available on the Extra tab.
-These actions are only available in the Pro Edition of Game Maker.
-
-
-Particle systems are meant to create special effects. Particles are small
-elements (represented by a pixel or a little shape). Such particles move
-around according to predefined rules and can change color while they move.
-Many such particles together can create e.g. fireworks, flames, rain, snow,
-star fields, flying debris, etc.
-
-
-
-
-
-Game Maker contains an extensive particle system that can be accessed through
-functions. A more limited particle system can be accessed through the actions described below.
-
-
-A particle system can deal with particles of different types. After creating
-the particle system the first thing to do is specify the particle types. Using
-the actions below you can specify up to 16 types of particles. Each type has a shape,
-a size, a start color and an end color. The color slowly changes from the start color
-to the end color. Particles have a limited life time. In the type you specify the
-minimal and maximal life time of the particles. Particles also have a speed and a
-direction. Finally, gravity and friction can work on particles.
-
-
-After you specify the particle types you must create them at places in
-the room. You can either burst a number of particles of a particular type
-from a place or you can create a constant stream of particles appearing.
-Particles appear at emitters. The particle system can have up to 8 emitters
-working at the same time. So after you create the particle types you must
-create the emitters and tell them to burst or stream particles.
-
-
-Here is the complete set of actions. Best experiment with them to get the required effect.
-
-
-
- Create Part System
-This action creates the particle system. It must be called before any other actions
-can be used. You only need to call it once. You can specify the depth at which the
-particles are drawn. If you use a large positive depth the particles appear behind
-the instances. If you use a negative depth they appear in front of the instances.
-
-
- Destroy Part System
-This action destroys the particle system, freeing all its memory. Don't forget to
-call this (e.g. when you move to a different room) because particle systems use a lot of storage.
-
-
- Clear Part System
-This action removes all the particles currently visible. It does not stop the emitters
-so new particles might be created again if you have streaming emitters (see below).
-
-
- Create Particle
-With this action you create a particle type. You can choose one of the 16 types
-available. For the particle type you can specify its shape or the sprite to be
-used for it. If you specify a sprite the sprite will be used. If you set the sprite
-to no sprite, the shape will be used. There are a number of interesting built-in
-shapes. You also indicated its minimal and
-maximal size (when the particle appears a random value between these bounds is
-used). Finally you specify the increase in size in each step. For a decrease, use
-a negative value. Note that only a particle type is created, not an actual particle.
-For this you need emitters (see below).
-
-
- Particle Color
-A particle can have a color (default the color is white). With this action you can
-set the color to be used for a particular type. You must indicate the particle type
-the color is defined for. Next you specify how a color is applied. Either a random
-color is choosen between two given colors, or the color starts with the first color
-and than gradually over the lifetime of the particle, it changes to the second color.
-Both colors must be given. Finally you can indicate the alpha transparency. You specify
-the transparency at the moment the particle is created and when it dies. The transparency
-slowly changes between these values. It is normally nice to decrease the alpha value over the
-lifetime of a particle.
-
-
- Particle Life
-A particle lives for a limited number of steps. After this is disappears. With this
-action you set the life time for a particle type. You give two limiting values and the actual
-life time is chosen randomly between them.
-
-
- Particle Speed
-With this action you can set the speed and direction of motion for a particle type.
-Again you give two limits and the actual value is chosen randomly between them. For
-example, to make the particle move in a random direction, give 0 and 360 for the
-limits for the direction. You can also specify a friction. This amount is subtracted
-from the speed in each step until it becomes 0. (You can make a particle speed up
-by using a negative friction.)
-
-
- Particle Gravity
-With this action you set the amount of gravity and direction of gravity for a
-particular particle type. 270 is downwards.
-
-
- Particle Secondary
-This is a bit more complicated. Particles can create other particles during their
-life time and when they die. With this action you can specify this. You can define
-the type and number of particles that must be created at each step during the life
-time and you can specify the type and number of particles that must be created when
-the particle dies. Be very careful here. You can easily create huge numbers of
-particles in this way, slowing down the system considerably. For the numbers you
-can also use a negative value. A negative value x means that in each step a
-particle is created with chance -1/x. So for example, if you want to generate a
-secondary particle about every 4 steps, use a value of -4. Secondary particles
-are great for creating effects like tails of particles or exploding particles.
-
-
- Create Emitter
-This action creates a particle emitter. Particles are generated by emitters.
-You can have up to eight emitters. Choose the emitter and specify the shape of
-it and its size and position (in the form of a bounding box).
-
-
- Destroy Emitter
-This action destroys the indicated emitter. Note that existing particles that
-came from this emitter are not removed.
-
-
- Burst from Emitter
-Even if you defined a particle type and an emitter there are still no particles.
-You still have to tell the emitter to generate the particles. With this action you
-tell a particular emitter to generate a given number of particles of a given type.
-All these particles are generated at once. For the number you can also use a negative
-value. A negative value x means that a particle is created with chance -1/x. So for
-example, if you want to generate a particle with a chance of 25 percent, use a value of -4.
-
-
- Stream from Emitter
-With this action you tell a particular emitter to stream a given number of particles
-of a given type. In each step this number of particles is generated, leading to a
-continuous stream of particles. The emitter will continue streaming particles until
-you destroy it or tell it to stream 0 particles. For the number you can also use a
-negative value. A negative value x means that in each step a particle is created
-with chance -1/x. So for example, if you want to generate a particle about every
-4 steps, use a value of -4.

-Finally, there are an additional action that can be useful in certain games.
-
-
-
- Set Cursor
-You can use this action to replace the windows mouse cursor by a sprite.
-You specify the sprite and whether the windows mouse cursor should still be shown.

Constants
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-In advanced mode you can define constants that you can use in scripts and
-in values for actions. Each constant has a name
-and a value. Names should follow the same rules as variables, that is,
-they must start with a letter or underscore symbol and further consist
-of letters, digits or underscore symbols. You are though strongly
-recommended to make all your constants easily distinguishable. A usual
-convention is to use only capital letters and underscores.
-
-
-To define constants you chose Define Constants from the Resources menu.
-The following form will show (in which already some constants have been defined):
-
-
-
-
-
-
-At the top you see the constants. At the left there is the name and at the right the
-value. You can select the name or value with the mouse and change it by typing.
-A value of a constant should be a constant expression. That is, it is
-either a constant number or a string (with quotes around it) or it is an
-expression. The expression is evaluated before anything else happens
-in the game. So it for example cannot reference the current room, instances, or
-scripts. But it can contain the built-in constants and the names of
-resources.
-
-
-You can append a constant at the end of the list using the button Add (or by pressing Enter)
-and delete it using
-Delete. You can also insert a constant above the current selected constant.
-There are also buttons to clear all constants, to move them
-up or down in the list, and to sort them by name.
-
-
-Finally you can save all constants to a text file or load them from a text file. This is useful when you want
-to store collections of useful constants for later use. When loading constants they are appended to the current list.
-The text file can also be editor using a text editor. Each line contains a constant definition of the form
-NAME=VALUE.
-
-
-
-It is good practise to put any value that you use multiple times in a constant. Also, if you
-are not completely sure about a certain value you better put it in a constant as it is a
-lot easier to change the constants than to find the values in the scripts and actions and
-change them there.

Trigger events
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-In advanced mode a new type of events is available: trigger events. Trigger events
-you can define yourself. You specify the condition when the event must be executed.
-To define trigger events you chose Define Triggers from the Resources menu.
-The following form will show (in which already some triggers have been defined):
-
-
-
-
-
-
-At the left you see a list of all triggers that have been defined. Initially this list is empty.
-Below there are some buttons with the following function:
-
-
-
-
Add.
- Use this button to add a new trigger event to the list.
-
Delete.
- Deletes the currently selected trigger event to the list. Be careful to never
- delete a trigger event that is used in an object. It might lead to unexpected
- results.
-
Load.
- Loads a collection of triggers from a file. Such a file must have extension
- .gmtrg. The triggers from the file are added to the list of triggers.
-
Save.
- Saves the collection of triggers to a file. Such a file must have extension
- .gmtrg. In this way you can create your own collections of useful triggers that
- you can use in different games.
-
Clear.
- Clears the list of triggers. Be careful to only use this when no object uses
- any trigger event.
-
-
-
-Once you are finished you can press the OK button to save the changes. If you do not
-want to save the changes, close the form with the cross in the top right corner and indicate
-that you do not want to save changes.
-
-
Defining a trigger
-
-
-Once you added a trigger you should fill in its properties. First of all you must give the trigger a name.
-This name will appear in the menu with available triggers and in the event lists for objects. Next you
-must specify the condition that will trigger the event. This is a piece of GML-code. It must contain
-a return statement that returns a true or false value. The trigger will fire when the return value is true.
-Here are some examples.
-
-
-Assume you want to create an event that happens when the player presses both the Control key and the A key.
-For this you can use the following condition:
-
-
-You can put complete scripts in the condition as long as there somewhere is a return statement. For
-example, to have an event that happen when the number of balls is between 3 and 5, you can use the
-following condition:
-
-
-
-
-{
- var n;
- n = instance_number(obj_ball);
- return (n >= 3) && (n <= 5);
-}
-
-
-
-
-You can create many other type of trigger events. For example events that check for combinations of
-keys and mouse buttons, events that check whether you are near to an enemy, events to check whether
-you collected enough money or score, etc.
-
-
-If the condition gets a bit long you might want to edit it in the code editor instead. To that end press
-the button Use code editor.
-
-
-
-After you specified the condition you should specify when the condition is tested. There are three options
-here. You can test the condition at the beginning of a step (just before the begin step event), in
-the middle (just before the normal step event) or at the end (just before the end step event). Most
-of the time the default middle position is fine but in certain cases you need the other moments.
-
-
-
-Finally, when you also want to call the event from code you can specify a constant with which you
-can refer in code to the event. See Chapter 4 for more details about calling events from code.
-
-
-
Using a trigger
-
-
-Once you have defined your scripts you can use them when defining objects. When setting the object
-properties and click on Add Event, you can now select Trigger events.
-
-
-
-
-
-In the drop-down menu that appears you can select the type of trigger event you want to use. Now
-you can add actions to this event in the same way as you add actions to other events.

-
Including files in stand-alone games
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-As has been indicated before, you can create stand-alone versions of your game.
-Sometimes your game will use additional files.
-For example you might want to include video files or text files that are used in the game. In some
-cases you want to add DLLs or images and sounds that are loaded during the running
-of the game. You can provide these together
-with the stand-alone executable but it is sometimes easier to include them
-in the file. In this way only one file needs to be distributed. Included
-files will default be exported when the game starts.
-
-
-You can indicate the files you want to include in the executable in
-by choosing Included Files from the Resources menu. The following
-form will be shown:
-
-
-
-
-
-At the top of the form is a list of files to include.
-Use Add to add a new file to the list, Change to change
-a selected file, Delete to delete the selected file, and Clear
-to clear the complete list. When adding or changing an entry, the following form will pop up:
-
-
-
-
-
-Here you can indicate a number of properties. You can press the Load button to indicate
-which file must be included. You can change the File Name if you want to save the
-file under a different name than the original file name.
-
-
-There are a number of options you can set. When you check Store in the editable gmk file the
-included file in not only added to the executable but also to the editable version of the game.
-The advantage is that you can e.g. send the editable version to somebody else and can be sure
-the file is still there. Also, you can remove the included file if you want or move it elsewhere
-without problems. The disadvantage is that the editable version of the game becomes larger and
-takes longer to load.
-
-
-Checking the option Free memory after export means that after the file has been exported
-(when running the game) it will be removed from memory. If you want to be able to export it again
-later you should uncheck this option.
-If a file that is exported already exists it is normally not written. You can change this
-behavior by checking Overwrite existing files. Also, when the game is finished the
-files are normally not removed (unless they are in the temporary folder which is completely
-removed). You can change this by checking Remove at game end.
-
-
-A word of warning is in place here. If you are testing your game, the working directory
-of the game is the directory where the .gmk file is stored. If your include files are also
-stored here and you choose to remove them at the end of the game you might loose them
-alltogether! So better not store these files with the .gmk file but e.g. in a subfolder!
-
-
-Finally you can indicate to what folder the files are exported.
-There are four options here. In the
-default situation the files are exported in the folder where the stand-alone game is
-stored. This is also the working directory for the game. So the game can just use
-the file names to access them (no paths are required). This works well if the stand-alone
-is stored e.g. on the hard disk but will fail if it is stored on a read-only device,
-e.g. on a CD.
-
-
-The second possibility is to indicate that the files must be exported into the temporary
-folder that is created during the running of the game. If you select this option you will
-need to provide the path to the temporary folder when you use the file name during the
-game. This path can be
-obtained using the built-in variable temp_directory. Don't forget to
-add the backslash in this case. So to e.g. play a video file you might type in
-the following piece of code:
-
-
-Realize that this temporary folder is removed once the
-game is finished. So you e.g. cannot store save games or special information in this case.
-Only choose this option when you want the game to be run from a CD or when you do not
-write any files from within your game.
-
-
-The third option is to indicate the folder to which the file must be exported yourself.
-If it does not exist it will be created. E.g. you could specify C:\MyGame. (Note
-that you need to provide a full patgh and that you should not include a backslash at the end.)
-This is only allowed when the game does not run in secure mode.
-
-
-Finally, you can indicate not the export the file automatically. In this case you should
-use e.g. the function export_include_file(fname) to export it yourself when
-required.

More about rooms
-
-Rooms in Game Maker have many options. Before we only treated the
-most important ones. In this chapter we will discuss the other options. When
-you open the room form in advanced mode it looks as follows:
-
-
-
-
-
-As you will see, some new buttons have been added to the toolbar. There are
-buttons to sort the instances horizontally or vertically. This is useful
-when instance partially overlap. (When adding tiles these buttons and the
-others work on the tiles rather than the instances.) Also there are buttons
-to lock all instances or unlock all instances. Locked instances cannot be
-moved or deleted. This protects you against incidentally removing instances.
-(However, when using the toolbar buttons to delete or shift
-all instances, also the locked ones are deleted or shifted.)
-Using the right mouse button menu (hold <Ctrl> and right click on an
-instance) you can also lock or unlock individual instances.
-
-
-Finally, you can indicate that you want to use an isometric grid. This is
-very useful when creating isometric games. First of all, the grid lines now
-run diagonally. Also the snapping of instances is different. (It works best
-when the origin of the instance is at the top left corner as is default.)
-
-
-Also there are two new tabs which we will discuss below.
-
-
-
-
-
-Information on the different advanced room options can be found in the
-following pages:
-
-
-
-There were two aspects in the settings tab that we have not yet
-discussed. First of all, there is a checkbox labeled Persistent.
-Normally, when you leave a room and return to the same room later, the room
-is reset to its initial settings. This is fine if you have a number of
-levels in your game but it is normally not what you want in for example an
-RPG. Here the room should be the way you left it the last time. Checking the
-box labeled Persistent will do exactly that. The room status will be
-remembered and when you return to it later, it will be exactly the same as
-you left it. Only when you restart the game will the room be reset.
-Actually, there is one exception to this. If you marked certain objects as
-being persistent, instances of this object will not stay in
-the room but move to the next room.
-
-
-Secondly, there is a button labeled Creation code. Here you can type
-in a piece of code in GML (see later) that is executed when the room is
-created. This is useful to fill in certain variables for the room,
-create certain instances, etc. It is important to understand what exactly
-happens when you move to a particular room in the game.
-
-
-
First, in the current room (if any) all instances get a room-end
- event. Next the non-persistent instances are removed (no destroy event is
- generated!).
-
Next, for the new room the persistent instances from the previous room
- are added.
-
All new instances are created and their creation events are executed
- (if the room is not persistent or has not been visited before).
-
When this is the first room, for all instances the game-start event is
- generated.
-
Now the room creation code is executed.
-
Finally, all instances get a room-start event.
-
-
-
-So, for example, the room-start events can use variables set by the creation
-code for the room and in the creation code you can refer to the instances
-(both new ones and persistent ones) in the room.
-
-
-There is one further option. In the pop-up menu when you right click on an
-instance with the <Ctrl> key you can now indicate some creation code
-for the specific instance. This code is executed when the room is started,
-just before the creation event of the instance is executed. This is very
-useful to e.g. set certain parameters that are specific to the instance.

-Adding tiles

Adding tiles
-
-You can also create so-called tiled background. The idea behind this is as
-follows: In many games you will want to have nice looking backgrounds. For
-example, in a maze game, the walls of the maze should nicely match up, and
-in platform games you like to see beautifully drawn platforms, trees, etc.
-You can do this in Game Maker by defining many different objects and
-composing your rooms from these objects. The problem though is that this
-takes a lot of work, uses large amounts of resources, and makes the games
-run slowly because of the many different objects. For example, to create nice
-walls in maze games you need as a start 15 differently shaped wall objects.
-
-
-The standard way out, used in many games, is that the walls and other static
-objects are actually drawn on the background. But, you might ask, how does
-the game know that an object hits a wall if it is drawn on the background
-only? The trick is as follows: You create just one wall object in your game.
-It must have the right size but it does not need to look nice. When creating
-the room, place this object at all places where there is a wall. And, here
-comes the trick, we make this object invisible. So when playing the game you
-don't see the wall objects. You see the beautiful background instead. But
-the solid wall objects are still there and the instances in the game will react
-to them.
-
-
-You can use this technique for any object that is not changing its shape or
-position. (You cannot use it when the object must be animated.) For
-platform games, you probably need just one floor and one wall object, but
-you can make beautifully looking backgrounds where it looks as if you walk
-on grass, on tree branches, etc.
-
-
-To add tiles to your room you first need to add a background resource to your
-game that contains the tiles.
-If you want to have your tiles partially transparent, make sure you
-make the background image transparent when loading it. When adding the background resource
-indicate that it must be used as a tile set. Next indicate the size of
-each tile and whether there is room between the tiles, as was indicated in
-the chapter on background resources.
-
-
-Now, when defining your room, click
-on the tab tiles. The following form is shown (actually, we already
-added some tiles in this room and switched off the grid).
-
-
-
-
-
-At the left top there is the current set of tiles used. To select the set,
-click on the menu button below it and select the appropriate background
-image.
-
-
-Now you can add tiles by selecting the tile you want at the top left, and
-next clicking at the appropriate place in the room at the right. This works
-in exactly the same way as for adding instances. Underlying tiles are
-removed, unless you uncheck the box Delete underlying. You can use
-the right button to delete tiles. Hold the <Shift> key to add multiple
-tiles. And hold the <Ctrl> key to move tiles to a new place. The
-<Alt> key will avoid snapping to the gird. Also there is again a pop-
-up menu when you hold the <Ctrl> key and click on a tile with the
-right mouse button. The buttons in the toolbar will now clear all tiles,
-shift all tiles, sort the tiles or lock/unlock them. (Actually they only
-operate on the current layer; see below.)
-
-
-In some situations you might want to put a part of the background in the
-room that is not exactly the size of a tile or consists of multiple tiles.
-This can be done as follows. In the top-left image press the left mouse button
-while holding the <Alt> key. Now you can drag an area which you can then
-place in the room in the same way as tiles. To select multiple tiles, hold the
-<Shift> key. Note that this only works correctly when there is no
-separation between the tiles. If you want to select an area that is multiple
-of the room grid size, hold the <Ctrl> key rather than the <Shift> key.
-(Note that you can actually change the key you hold during the dragging. This
-can sometimes be useful.)
-
-
-Tiles can be placed in layers at different depths. At the bottom you see the
-current depth. Default this is 1000000 which is normally behind all
-instances. So the instances will move in front of the tiles. You can use the
-Add button to add new tile layers, each with a different depth.
-Negative depths can be used to put tiles in front of instances. If you also
-give objects different depths you can put them between different tile
-layers. If you press Delete you delete a tile layer together with all
-its tiles. (There must always be at least one layer.) If you press Change
- you can change the depth of a tile layer. If you give it the same depth
-as another layer, the layers are merged.
-
-
-Using tiles is a powerful feature that should be used as much as possible.
-It is much faster than using objects and the tile images are stored only
-once. So you can use large tiled rooms with very little memory consumption.

Views
-
-Finally, there is a tab labeled views. This gives a mechanism for
-drawing different parts of your room at different places on the screen.
-There are many uses for views. First of all, in a number of games you want
-to show only part of the room at any time. For example, in most platform
-games, the view follows the main character. In two-player games you often
-want a split-screen mode in which in one part of the screen you see one
-player and in another part you see the other player. A third use is in games
-in which part of the room should scroll (e.g. with the main character) while
-another part is fixed (for example some status panel). This can all be
-easily achieved in Game Maker.
-
-
-When you click the tab labeled views the following information will
-show:
-
-
-
-
-
-At the top there is a box labeled Enable the use of Views. You must
-check this box to use views. Below this you see the list of at most eight
-views you can define. Below the list you can give information for the views.
-First of all you must indicate whether the view should be visible when the
-room starts. Make sure at least one view is visible. Visible views are shown
-in bold.
-
-
-A view is defined by a rectangular area in the room. This is the area that
-must be shown in the view. You specify the position of the top-left corner and
-the width and height of this area. Secondly, you must specify where this area is
-shown in the window on the screen. This is called the (view)port.
-Again you specify the position of the top-left
-corner and the size. If you have a single view the position is typically (0,0).
-Note that the size of the port can be different from the size of the view. In this
-case the view will be scaled to fit in the port. (In code it is
-also possible to rotate a view.) The ports can overlap. In this
-case the are drawn in the indicated order on top of each other.
-
-
-As indicated above, you often want the view to follow a certain object. This
-object you can indicate at the bottom. If there are multiple instances of
-this object, only the first one is followed by the view. (In code you can
-also indicate that a particular instance must be followed.) Normally the
-character should be able to walk around a bit without the view changing.
-Only when the character gets close to the boundary of the view, should the
-view change. You can specify the size of the border that must remain visible
-around the object. Finally, you can restrict the speed with which the view
-changes. This might mean that the character can walk off the screen, but it
-gives a much smoother game play. Use -1 if you want the view to change
-instantaneously.

Fonts

-To create a font resource in your game, use the item Create Font in the Resources menu or use
-the corresponding button on the toolbar. The following form will pop up.
-
-
-
-
-
-As always you should give your font resource a name. Next you can pick the name of the font. Also you can
-indicate its size and whether it should be bold and/or italic. Realize that large fonts take a lot of
-memory to store. So you are strongly recommended not to use fonts with a size larger than say 32. (It
-is possible to scale the fonts while running the game.) An example of the indicated font is shown at the bottom.
-
-
-A font typically consist of 256 characters, numbered from 0 to 255.
-But in general you use only a small portion of
-these. So default in a font only the characters from 32 till 127 are stored in the font. The more characters you
-store in the font the more memory it will use. You can change the character range used. To see the index of
-each character you can use the Character Map that can be found in the
-Windows Start menu under Accessories/System Tools.
-Some standard ranges can be indicated using the buttons: The Normal range from 32 till 127, the All
-range from 0 till 255, the Digits range that only contains the 10 digits, and the Letters
-range that contains all uppercase and lowercase letters. Other ranges can be used by typing in the
-first and last character index. If a character does not lie in the range it is replaced by a space.
-
-
-Normally you have a large number of different fonts
-installed on your computer and there are websites where you can download hundreds more. The problem is that
-if you use them in your game and then give your game to somebody else to play there is a big chance that
-the other person does not have the same fonts installed on his or her computer.
-To avoid this, Game Maker embeds all the fonts you want to use in the game file, but only in
-the stand-alone games. So if you give a stand-alone game to someone else you don't need to provide
-the font files. But if you give somebody the editable version of your game and you use fancy fonts, you
-better also provide the person with the correct font files.

Paths
-
-In more advanced games you often want to let instances follow certain paths.
-Even though you can indicate this by e.g. using timer events or code, this
-is rather complicated. Path resources are an easier mechanism for this. The
-idea is rather simple. You define a path by drawing it. Next you can place
-an action in the creation event of the object to tell the object to
-follow the particular path. This chapter will explain this in detail.
-
-
-
-
Defining paths
-
-To create a path in your game, choose Create Path from the Resources menu.
-The following form will pop up (in the example we already added a little
-path).
-
-
-
-
-
-At the top left of the form you can set the name of the path, as usual.
-Below it you find the points that define the path. Each point has both a
-position and a speed (indicated with sp). Depending on how you use the path,
-the position is either absolute, that is, the instance for which you will
-later use the path will follow it at that particular place, or it is
-relative, that is, the instance will always start at the first position on
-the path and follow the path from there. The speed should be interpreted as
-follows. A value of 100 means the original speed given for the path when
-assigning it to the instance. A lower value reduces the speed, a higher
-value increases it (so it indicates the percentage of the actual speed).
-Speed will be interpolated between points, so the speed changes gradually.
-
-
-To add a point press the button Add. A copy is made of the currently
-selected point. Now you can change the actual position and speed by changing
-the values in the edit boxes. Whenever you select a point in the list, you
-can also change its values. Press Insert to insert a new point before
-the current one, and Delete to delete the current point.
-
-
-At the right of the form you will see the actual path. The red dot indicates
-the currently selected control point. The blue dots are the other control
-points. The green square indicates the position where the path starts. You
-can also change the path using the mouse. Click anywhere on the image to add
-a point. Click on an existing point and drag it to change its position. When
-you hold <Shift> while clicking on a point, you insert a point.
-Finally, you can use the right mouse button to remove points. (Note that you
-cannot change the speed this way.) Normally the points will be aligned with
-a grid. You can change the grid settings at the top tool bar. Here you can
-also indicate whether the grid should be visible or not. If you want to
-precisely position a point, hold the <Alt> key while adding or moving
-it.
-
-
-You can influence the shape of the path in two ways. Fist of all you can use
-the type of connection. You can either choose straight line connections or a
-smooth path. Secondly, you can indicate whether the path must be closed or
-not.
-
-
-On the toolbar there are a number of important controls. From left to right
-they have the following meaning. The first button indicates that you are
-ready and want to close the form, keeping the changes. (If you want to
-discard the changes, press the cross to close the window and indicate that
-you do not want to save the changes.) Next there is the button to undo the
-last change.
-
-
-The following set of toolbar buttons allows you the clear the path, reverse
-the order in which the path is traversed, shift the path, mirror it
-horizontally, flip it vertically, rotate it, and scale it. Next there are
-buttons to shift the view (not the path itself; the actual view area is
-indicated in the status bar at the bottom) and to center the view.
-
-
-As already indicated above you can next set the snap values and whether to
-show the grid. Finally there is a button to indicate that you want to see a
-particular room as background for the path. Using this you can easily put
-the path at a particular place in the room, for example on a race track,
-so that later the instances will follow the correct route. (This only
-makes sense when you use absolute paths; see below.)
-
-
-
-
Assigning paths to objects
-
-To assign a path to an instance of an object, you can place the path action
-in some event, for example in the creation event. In this action you must
-specify the path from the drop down menu. There are some further values you
-can provide.
-
-
-You must indicate the path that must be followed and the speed in pixels per
-step. When the speed is positive the instance starts at the beginning of the
-path. If it is negative it starts at the end. Remember that when you defined
-the path you specify the actual speed relative to this indicated speed.
-There is also an action to change the speed with which the path is executed.
-You could, for example, use this to let an instance slow down or speed up along its
-path. Note that the normal speed of the instance is ignored (actually set to
-0) when executing a path. Also things like gravity and friction do not
-influence the motion along a path.
-
-
-Next you specify the end behavior, that is, what should happen when the end
-of the path is reached. You can choose to stop the motion and end the path.
-You can also restart the path from the beginning, that is, the instance
-jumps back to the position where the path was started and executes the path
-again. A third option is to restart from the current position, that is, the
-instance follows the path again but now with this new starting position
-(this is the same when the path is closed). Finally you can choose to
-reverse the motion, making the instance go back and forth along the path.
-Note that also at the end of the path an event happens; see below.
-
-
-Finally you can indicate whether the path must be absolute or relative. An
-absolute path is executed at the place where it is defined. The instance is
-placed at the start position and moved from there (end position when speed
-is negative). This is, for example, useful when you have a race track on
-which you have defined the path. When you choose relative the instances starts
-executing the path from its current position. This is useful when an
-instance should make a local motion. For example, space ships in a space
-invader game can make a particular turn from their current position.
-
-
-When you want to place the instance at a different point along its path you
-can use the action to set the path position. A path position always lies
-between 0 and 1, 0 indicating the start position and 1 the end position on
-the path. Note that in each step the direction variable is automatically set
-to the correct direction along the path. You can use this variable to
-choose the correct orientation for the sprite.
-
-
-When using scripts or pieces of code you have more control over the way the
-path is executed. There is a function to start a path for an instance. The
-variable path_position indicates the current position on the path
-(between 0 and 1 as indicated above). The variable path_speed
-indicates the speed along the path. A variable path_scale can be
-used to scale the path. A value of 1 is the original size. A larger value
-indicates that the path is made larger; a smaller value makes it smaller.
-The variable path_orientation indicates the orientation in which
-the path is executed (in degrees counter-clockwise). This enables you to
-execute the path in a different orientation (e.g. moving up and down rather
-than left and right). There is also a variable to control the end behavior.
-Finally there are lots of functions to ask for properties of paths (e.g. the
-x and y coordinate at a certain positions) and there are functions to create
-paths. There are even functions that create collision free paths for an
-instance to reach a certain goal. See the later sections on GML for details
-on this.
-
-
-You might wonder what happens when the instance collides with another
-instance while it follows a path. Basically the same happens as when the
-instance moves with a speed. When there is a solid instance, the instance is
-placed back at its previous location. When both instances are not solid they are
-placed at their new positions Next the collision event(s) are executed and
-it is checked whether the collision has been resolved. If not and the other
-instance is solid the instance will stop, as it should (assuming there is a
-collision event defined). Also, the path_position variable is not
-increased. When the blocking instance disappears the instance will continue
-to follow its path. To handle collisions yourself the variable
-path_positionprevious can be useful. It holds the previous position for
-the path and you can set the path position to this variable to avoid
-advancing along the path.
-
-
-
-
The path event
-
-As described above, you can indicate what must happen when the instance
-reaches the end of the path. At this moment also an End of Path event
-occurs. You can find it under the Other events. Here you can place
-actions. For example, you might want to destroy the instance, or let it
-start a new (different) path.

Time lines
-
-In many games certain things must happen at certain moments in time. You can
-try to achieve this by using alarm events but when things get too
-complicated this won't work any more. The time line resource is meant for
-this. In a time line you specify which actions must happen at certain
-moments in time. You can use all the actions that are also available for the
-different events. Once you create a time line you can assign it to an
-instance of an object. This instance will then execute the actions at the
-indicated moments of time. Let us explain this with an example. Assume you
-want to make a guard. This guard should move 20 time steps to the left, then
-10 upwards, 20 to the right, 10 downwards and then stop. To achieve this you
-make a time line where you start with setting a motion to the left. At
-moment 20 you set a motion upward, at moment 30 a motion to the right, at
-moment 50 a motion downwards and at moment 60 you stop the motion. Now you
-can assign this time line to the guard and the guard will do exactly what
-you planned. You can also use a time line to control your game more
-globally. Create an invisible controller object, create a time line that at
-certain moments creates enemies, and assign it to the controller object. If
-you start to work with it you will find out it is a very powerful concept.
-
-
-To create a time line, choose Create Time Line from the Resources menu.
-The following form will pop up.
-
-
-
-
-
-It looks a bit like the object properties form. At the left you can set the
-name and there are buttons to add and modify moments in the time line. Next
-there is the list of moments. This list specifies the moments in time steps
-at which assigned action(s) will happen. Then there is the familiar list of
-actions for the selected moment and finally there is the total set of
-actions available.
-
-At the left you can use the following buttons:
-
-
-
Add. Use this to add a moment to the time line. You must indicate the moment, which
- is the number of steps since the time line was started. Now you can
- drag actions to the list as for object events.
-
Change. Use this button to change the time steps for the currently selected moment.
-
Delete. Use this button to delete a moment or a range of moments. You must indicate the time step
- of the first moment to delete and the last one. All moments in between will be deleted.
-
Clear. Use this button to clear the entire list of moments.
-
Shift. Use this button to shift a range of moment to a new moment. You must indicate
- the start of the range, the end of the range, and the new time step to which the start of the
- range must be shifted. When different moments become the same their action lists will be merged.
-
Duplicate. This is almost the same as the shift button but in this case a copy of the moments
- are made.
-
Spread. Use this button to spread out a range of moments by adding time between them or put them
- closer together by removing time between them. You specify the start and the end of the range and the percentage
- for the spread. A percentage of 100 means nothing changes. For values smaller than 100 the moments are moved closer
- together and for values larger than 100 they are moved further apart. For example if you have moments at timesteps 5, 8,
- and 12 and you indicate as range 5:12 and a percentage 200, the moments will move to time steps 5, 11, and 19.
- (The intervals between them have doubled.) When different moments become the same their action lists will be merged.
-
Merge. Use this button to merge a number of moments into a single one. You specify the start and the
- end of the range and they will all be merged into the start moment.
-
-
-
-Make sure you do not create negative time moments. They will
-never be executed.
-
-
-There is also a button Show Information that shows the time line in a readable form.
-
-
-There are a number of actions related to time lines. You can find them in the section on
- More Main Actions.

Scripts
-
-
-Game Maker has a built-in programming language called GML. Once you become more
-familiar with Game Maker and want to use it to its fullest extend, it
-is advisable to start learning to use this language. For more details in the
-GML language see Part 4 of this documentation.
-
-
-
-There are two ways to
-use the language. First of all you can create scripts. These are pieces of
-code to which you give a name. They are shown in the resource tree and can be
-saved to a file and loaded from a file. They can even be used to form a library
-that extends the possibilities of Game Maker. Alternatively, you can
-add a code action to some event and type a piece of code there. Adding code
-actions works in exactly the same way as adding scripts except for two
-differences. Code actions don't have a name and cannot use arguments. Also
-they have the well-known field to indicate to what objects the action should
-apply. For the rest you enter code in exactly the same way as in scripts. We
-recommend you to use scripts for all but simple pieces of code as Game Maker
-has many more features that deal with scripts.
-So we further concentrate on scripts in this chapter.
-
-
-
-As stated before, a script is written with code in GML (the built-in programming language)
-and is meant to perform a particular task. Scripts can takes input-variables called arguments
-(sometimes called parameters). To execute a script from any event, you can use
-the script action. In the script action you specify
-the script you want to execute, together with the up to five arguments.
-
-
-
-You can also execute a script from within a piece of code (a different script) in the same way you
-call a GM-function. In that case you can use up to 16 arguments.
-Scripts can return a value. This is often used to build calculating methods
-(mathematical methods). The return keyword is used for this.
-No code after the return keyword is executed!
-When a script returns a value, you can also use it as a function when
-providing values in other actions.
-
-
-
-Scripts are extremely useful to extend the possibilities of Game Maker.
-This does though require that you design your scripts carefully. Scripts
-can be stored in files that can be added to your game. To import a
-script file, use the item Import scripts from the Scripts menu. To save your
-scripts in the form of a file use Export scripts. Script libraries
-are simple text files (although they have the extension .gml). Preferably
-don't edit them directly because they have a special structure.
-
-
-
-To create a script in your game, choose Create Script from the Resources menu.
-A code editor will appear that will be described next.
-
-
-
-
The code editor
-
-
-When creating or editing a script (or a code action) the following code editor form
-will appear (in the example we already added a
-little script that computed the product of the two arguments).
-
-
-
-
-
-
-
-At the top right you can indicate the name of the script. You should give all
-of your scripts a sensible name. Make sure the name only consists of letter, digits,
-and the _ symbol. It should not start with a digit. In this way you can use the
-script later as a function in code.
-
-
-
-At the top you have a toolbar with some useful buttons. From left to right you
-have the OK button to close the editor, saving the changes, buttons to load the
-script from a text file, save it to a text file, and print it.
-
-
-
-Next there are undo and redo buttons. The editor will basically remember all
-changes you did and you can undo them (or redo the undone changes). You can change
-the maximal number of undo operations in the Preferences. Here you can also
-indicate whether you want to group the undo operations (such that e.g. typing
-a line of text can be undone in one step) or that every keystroke is separate
-saved. You can use <Ctrl> + Z for undo and <Ctrl> + <Shift> + Z for
-redo.
-
-
-
-Next to this there are buttons to cut, copy, and paste text, as you should be familiar
-with. The final two buttons are for finding and replacing and for code checking. These will
-be explained below in detail.
-
-
-
-Below the toolbar there is the area where you can type the text. At the left there are the
-line numbers. (You can switch these on and off using the F9 key.) The line with the cursor
-on it is marked in bold. The dark red bar behind certain line numbers indicated that these
-lines have changed. You will notice that you can type text anywhere on the lines. So
-a line does not really have an end. This tends to be useful when alligning text. There
-are many editing possibilities, that will be described below.
-
-
-
-At the bottom there is the status bar. This shows from left to right the current line number,
-total number of lines and cursor position. Whether you are in Insert mode or Overwrite mode. (In
-Overwrite mode also the cursor chnanges to make it clear that you are overwriting the existing text.)
-Next there is the point size for the font used. You can use F7 and F8 to decrease or increase the
-font size. (You have more control over the font size and type in the Preference.)
-
-
-
-
Editing tools
-
-
-The editor has many editing possibilities. Some of these can also be accessed through the
-pop-up menu that appears when you press the right mouse button. Here are the most important ones:
-
-
-
-
Multiple undo and redo either per key press or in groups
-
The arrow keys move you around in the text. Use <Ctrl> with
- the left and right arrow key to move to the beginning of the previous
- or next word. Use <Ctrl> with the up and down key to also scroll
- the text. Hold the <Shift> key to select text.
-
Double click the line number to select the complete line.
-
The Home key moves to the beginning of the line and the End key
- to the end of the line. With <Ctrl> they move to the start and end of the
- script. Hold the <Shift> key to select text.
-
You can scroll through the text with the mouse wheel.
- With <Ctrl> the cursor scrolls with the text. Hold the <Shift> key to select text.
-
Intelligent auto indent that aligns with the previous line when you use the
- return key of the backspace key (can be set in the preferences).
-
Intelligent tabbing that tabs till the first non space in the previous
- lines (can be set in the preferences).
-
Use <Ctrl> + I to indent selected lines and <Shift> +
- <Ctrl> + I to unindent selected lines.
-
Hold <Ctrl> with the Backspace or Delete key to delete until the
- beginning of the previous or next word.
-
You can drag a selection with the mouse. (Use <Ctrl> to copy it.) The new location is immediately shown.
-
Cut, copy and paste of text between script forms and other programs.
-
Use F12 to open the script or resource whose name is at the cursor
- position.
-
-
-
-
Color coding
-
-
-As you might have noticed, parts of the script text are colored. The editor
-knows about existing objects, built-in variables and functions, etc. Color-
-coding helps a lot in avoiding mistakes. In particular, you see immediately
-if you misspelled some name or use a keyword as a variable.
-If you don't like the color coding, in the Preferences you can switch
-it on and off (you can also use F10). In the Preferences you can also change the
-color for the different components of the code.
-
-
-
-
Function and variable help
-
-
-Game Maker contains many built-in functions and variables and you add your own
-resources and scripts to this. So it might be hard to remember all of them. Fortunately
-the editor helps you with this. When you type part of a name (at least two characters) and
-wait a little, a list is shown of all possibilities. For example, as follows:
-
-
-
-
-
-
-
-You can continue typing and the list will adapt. You can use the up and down keys to scroll through
-the list and press Enter to replace the text you are typing with the selected function or variable name.
-
-
-
-You can switch this feature on and off in the preferences. You can always force the list to appear
-by pressing <Ctrl> + Space.
-
-
-
-A second form of help is given when you are typing in the arguments for a function. In this case, in the
-status bar at the bottom the function with its arguments is given. The current argument you are typing is
-shown in bold. In this way you will never forget arguments or get the order wrong.
-
-
-
-
Find and replace
-
-
-It is common that you want to find some piece of text in your code or replace some text with another one.
-To this end press the Find button in the toolbar. A panel will show up at the right of the form, as follows:
-
-
-
-
-
-
-
-You can type the find string at the top. Note that in the code all occurrences of the find string are immediately shown
-with a yellow background. (You can switch this off in the Preferences.) As usual you can indicate whether the search
-must be case sensitive (which is normally what you want as variable and function names in GML are also case sensitive)
-and whether you want to only search for whole words. Note that the editor remembers your most recent searches.
-
-
-
-With the buttons with the blue arrows you can now move to the previous, next, first, and last occurrence of the
-find string. It will be selected in the text such that you can e.g. delete it.
-
-
-
-When you want to replace occurrences, also type a text in the replace box. Now you can use the buttons to replace the
-previous occurrence, the next, the first, the last, or all occurrences of the find text. Remember you can always
-use Undo to undo the replacements.
-
-
-
Code snippets
-
-
-Code snippets are small pieces of code that you will often use. You can add them in the code through the snippet menu.
-To this end press F2. A menu appears from which you can select the snippet. It will be inserted at the cursor in
-your code. Some pieces consists of capital letters only. These must still be replaced by you. The first one is
-selected for replacement. To replace another, simply double click on it.
-
-
-
-You can define your own code snippets if you want. The snippets are stored in the file snippets.txt in
-the folder in which Game Maker is installed. You can edit this file with any text editor. Each snippet is
-on a separate line and there should be no blank lines. It starts with the name of the snippet (shown in the menu)
-followed by the colon (:) followed by the actual snippet. Use # for a newline and put the text that needs to
-be selected first between | symbols. See the examples that are already in the file. (Better make a backup of
-it before you start changing it.)
-
-
-
-
Error checking
-
-
-In the toolbar at the top there is a button with which you can switch error checking on or off.
-When error checking is on, Game Maker constantly tests the code you are typing and reports
-the first error it finds at the bottom of the window. Also the line number for the line with the
-error is drawn in red. You can click on the error message to go to the correct line and position to
-correct the error. Note that not all aspects can be tested at this stage but the syntax of your
-script will be tested, together with the existence of functions used.
-
-
-
-When you start typing a script, error checking might be annoying so you can switch it off. But when the
-script is almost ready you better switch it on to correct all the errors. Note that also the
-color coding will help you catch errors. Finally, when you put your cursor at a bracket the editor
-will show you the corresponding opening or closing bracket. If it cannot find it, it is shown in red.
-(You can switch this off in the Preferences.)
-
-
-
-
Debugging
-
-
-When creating scripts you can easily make mistakes. Always test the scripts by
-using the error checking button. However, this will not catch all errors. So
-you will need to run the game to test your code.
-
-
-
-When an error occurs during the execution of a
-script this is reported, with an indication of the type of error, the script or
-action it occurs in, and the line and position.
-Rarely you will see a popup with the text
-"Unexpected error occurred during the game".
-This error message indicate that some problem occurred in windows or in
-the hardware. Often the reason for this is infinite recursion, lack of
-memory or insufficient hardware, drivers or firmware.
-Generally speaking, these errors have to do with problems outside the Game Maker environment.
-
-
-
-If you need to check things more carefully, you can run the game in
-debug mode. Now a form appears in which you can monitor lots of information
-in your game.
-
-
-
-
-
-
-
-Under the Run menu you can pause the game, run it step by step and
-even restart it. Under the Watch menu you can watch the value of
-certain expressions. Use Add to type in some expression whose value
-is shown in each step of the game. In this way you can see whether your game
-is doing things the right way. You can watch many expressions. You can save
-them for later use (e.g. after you made a correction to the game). Under the
-Tools menu you find items to see even more information. You can see a
-list of all instances in the game, you can watch all global variables (well,
-the most important ones) and the local variables of an instance (either use
-the object name or the id of the instance). You can also view messages which
-you can send from your code using the function show_debug_message(str).
-Finally you can give the game commands and change the speed of the
-game. If you make complicated games you should really learn how to use the
-debug options.

Extension Packages
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Extension packages extend the possibilities of Game Maker. An
-extension package can add a set of actions to Game Maker
-or it adds a number of additional functions and constants to the GML language
-built into Game Maker. When extension packages are
-available to you, help about these is placed in the Help menu.
-
-
-When double clicking on the Extension Packages resource item the following form is shown:
-
-
-
-
-
-In this form you can indicate which extension packages must be used
-in the game. On the left there is the list of Used packages and on the
-right is the list of Available packages. To move a package from one list
-to the other, simply select it and press the button between the list. When selecting
-a package a short description is given at the bottom. Further help is available
-by pressing the Help button.
-
-
-Extension packages are an extremely powerful part of Game Maker. A few
-extension packages are provided with Game Maker but many more will
-become available through the website. To install new packages or uninstall
-existing ones, press the Install button. The following form
-is shown
-
-
-
-
-
-You will see a list of all extension packages installed. By selecting a package
-and clicking the Uninstall button the package is removed from the system.
-
-
-Install packages are distributed in the form of a .gex file. You can find
-a number of such packages on our website which you can go to by pressing
-the button Find More. Once you donwloaded such a package file on
-your computer, press the Install button and select the package file.
-It will then be installed in the system.
-
-
-If you want to create your own extension packages, please check out
-the information that is available on
-http://www.yoyogames.com/extensions.

Exporting and importing resources
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Note: Import and export of resources is only for experienced users. Carefully read
-this section before using these features. Also, always make a back-up copy of your game
-before importing resources.
-
-
-Sometimes you want to copy certain resources (sprites, sounds, rooms, etc.) from one game
-to another game. For example when you want to create a new game using the same sprites and
-sounds as another game. Or when you are working together on a game. One of you might have
-created some additional rooms that you then want to import in the other game.
-To this end Game Maker has commands to import and export resources.
-
-
-
Exporting resources
-
-
-To export resources, choose Export Resources from the File menu. First of all
-it is checked whether all resources have different names. Because resources in one game are
-linked to the ones in the other game by name, it is essential that all resources have different
-names. If not, you get an error message and no resources can be exported. Otherwise, a file selector
-is shown in which you can indicate the name of the file in which you want to export the resources.
-These files must end with the extension .gmres. Next the following form is shown:
-
-
-
-
-
-
-In this form you can indicate which resources must be exported. Default all are exported but you can
-select the particular types of resources you want to export.
-Care must be taken when exporting objects, timelines, or rooms.
-These will refer to sprites, sounds, triggers, etc. So if you do not export these other resources as well
-you must be certain that these other resources already exist in the game in which you are going to
-import the resources (under the same names). If you are uncertain, better export everything.
-
-
-
Importing resources
-
-
-Once you have a file containing resources you can import them in a different game by
-choosing Import Resources from the File menu. First of all
-it is checked whether all resources have different names. Again, because resources in one game are
-linked to the ones in the other game by name, it is essential that all resources have different
-names. If not, you get an error message and no resources can be imported. Otherwise, a file selector
-is shown in which you can indicate the name of the file from which you want to import the resources.
-These files will end with the extension .gmres. Next all open property forms are closed.
-This is necessary because imported resources might replace
-existing ones. Next the following form is shown:
-
-
-
-
-
-
-All types of resources in the file are shown. (The ones that were not exported and grayed out.)
-You can select which of these resources you want to import. Most of the time you want to import all
-but sometimes you want to make a selection. Be careful when importing objects, rooms, or timelines
-while not importing other resources. As indicated above this can lead to problems if the resources they
-refer to do not exist in your game under the same name. In such a case they will be replaced by non-existing
-resources. (For example, in the rooms it means the corresponding instances will be removed.)
-
-
-
-When resources in the file have the same name as resources in the game a naming conflict appears. You can
-indicate how that should be resolved. The default is that you keep the resource that was changed last.
-You can however also choose to always keep the original in the game or always replace it with the
-resource in the file. A fourth option is to keep both. Only use this when it is absolutely necessary,
-because you will now end up with multiple resources with the same name which can lead to conflicts
-when referring to them. When you import resources into an empty game, better choose to always replace them.
-(This may sound strange but for example otherwise the global game settings will not be replaced as the new
-empty game is of a more recent date!)
-
-
-
-Finally you can indicate whether to place the new resources (that is, the ones that do not already occur) in
-a new group. This might be useful to distinguish (visually) the imported resources from the existing ones. If
-you check this box the new resources will be place in a group. The name of this group is the name of the
-import file.
-
-
-
-Once you press OK the resources are added to the game, replacing existing resources with
-the same name when required. You will see them appear in the resource selector at the left.
-
-
-
Warnings and Remarks
-
-
-Importing and exporting resources is a powerful mechanism, in particular when you are working
-on a game with multiple people. However, if you do not understand what you are doing it might
-lead to errors and frustration. Here are some important warnings that you should read and
-understand.
-
-
-
-
Always make a backup copy of your game before importing resources. Otherwise your hard
- work might be lost. You cannot undo the import of resources.
-
Always check after an import whether everything was imported correctly. Also immediately
- run the game to see if it all works. Otherwise return to your backup copy.
-
Note that the indices of resources, instances, and tiles, most likely change in the process to
- guarantee that they remain unique. This will cause problems
- when you refer to resources (or instances) by number. Also it will cause problems if you assume
- anything about the order in which instances are created.
-
Note that the resources will be added in the order in which they are given in the resource list/tree.
- New resources will be added at the end. However, the group structure is maintained.
- This is normally what you expect but in some rare cases
- you might have to move resources to a different location. For example, when you have a start room,
- an end room and some rooms in between, when somebody adds some rooms (in between) and you then export
- these and import them in the original game, they will appear at the end (because they are new). You then
- must move the end room to the appropriate location again.!
-
Note that constants and triggers only globally store information about when they were last changed.
- So when you change one constant or one trigger, all will be replaced when choosing
- Keep Last Changed.
-
For the global game settings the same holds. They are either all, or not at all replaced.
-
Note that an empty game will have a new date at which it was last changed. This means that if
- you import resources in a new empty game, the constants, triggers, and global game settings will
- not be imported, unless you set the name conflict handling to always replace.
-
Don't remove resources from a game before importing the same resources again! This might
- sound a logical thing to do but it will not work. Once you remove a resource from a game
- it no longer exists. Hence all references to it will become undefined. Importing the
- same resource later will not restore those references because the program cannot know
- it is the same resource. Instead let the import feature replace the resources.
-
If you have worked on a game for a long time adding and deleting many resources, it is useful
- to completely export it and then import it into an empty game (with the option to always replace).
- The game will work as before but will be stripped of lots of unused data.

Polishing your game
-
-When you want to distribute your game you better make sure that it has all the ingredients
-that make it a great game. Besides the game itself this means that you should provide
-game information, set the correct global game settings, and take care of speed.
-This section gives you information about these aspects.
-
-
-
-Information on finishing your game can be found in the following pages:
-
-
-
-A good game provides the player with some information on how to play the game.
-This information is displayed when the player presses the <F1> key during
-game play. Game Maker has a simple built-in mechanism to provide game
-help. However, it is limited in functionality. To create nicer games it is better
-to create the help yourself using special rooms or by using splash screen with
-e.g. html pages.
-
-
-To create the simple game information, double click Game Information
-in the resource tree at the left of the screen. A little built-in editor is
-opened where you can edit the game information. You can use different fonts,
-different colors, and styles. Also you can set the background color.
-
-
-
-
-
-In the File menu you can also set a number of Options.
-Default the help is shown in the game window and game play is temporarily
-halted. Here you can indicate to show the help file in a separate window.
-In this case you can indicate the caption of the game information during the game. Also
-you can indicate the position (use -1 for centered) and size of the game
-information window and whether it should have a border and be sizeable by
-the player. You can force the information window to stay on top and you
-can indicate whether the game should continue playing while the information
-is shown.
-
-
-Good advice is to make the information short but precise. Of course
-you should add your name because you created the game. All example games
-provided have an information file about the game and how it was created.
-You might want to indicate at the
-bottom of the help file that the user must press Escape to continue playing.)
-
-
-If you want to make a bit more fancy help, use a program like Word. Then select
-the part you want and use copy and paste to move it from Word to
-the game information editor. For more advanced games though you
-probably will not use this mechanism at all but use some dedicated rooms
-to show help about the game.

Global Game Settings
-
-There are a number of settings you can change for your game. These change the shape

Graphics options
-
-In this tab you can set a number of options that are related to the graphical
-appearance of your game. It is normally useful to check out the effects of these
-options because they can have a significant effect on the way the game looks.
-Remember though that different users have different machines. So better make sure
-that the settings also work on other peoples machines.
-
-
-Start in fullscreen mode
-When checked the game runs in the full screen; otherwise it runs in a window.
-
-
-Scaling
-Here you can indicate what happens when the window is larger than the room
-or when the game is run in full-screen mode. There are three choices. You can
-indicate a fixed scaling. The room is drawn scaled with the given amount in the
-center of the window or the center of the screen. 100 indicates no scaling.
-You typically use fixed scaling when your sprites and rooms are very small. The second
-option is scale the room such that it fills the window or screen but keep
-the aspect ratio (ratio between width and height) the same. The third
-option is to scale such that the window or screen is completely filled. This
-can lead to distortions in the image (in particular in windowed mode when
-the user can resize the window).
-
-
-Interpolate colors between pixels
-When checked, colors of pixels in sprites, backgrounds, and tiles that are not
-aligned with pixels on the screen will be interpolated. This in particular is the
-case when they are scaled, rotated, or placed at non-integer positions. Interpolation
-makes movement smoother but can also give a blurred effect. (Also for tiles it can
-lead to cracks between them, if not carefully designed.)
-
-
-Color outside the room region
-When the room does not completely fill the window or screen there is some area
-unused around it. Here you can specify the color of the area.
-
-
-Allow the player to resize the game window
-When checked in windowed mode the user can change the size of the game window by
-dragging with the mouse at its corners.
-
-
-Let the game window always stay on top
-When checked in windowed mode the game window always stays on top of other windows.
-
-
-Don't draw a border in windowed mode
-When checked in windowed mode the game window will not have a border or a caption bar.
-
-
-Don't show the buttons in the window caption
-When checked in windowed mode the window caption will not show the buttons to
-close the window or to minimize or maximize it.
-
-
-Display the cursor
-Indicates whether you want the mouse pointer to be visible. Turning it off is
-normally faster and nicer.
-(You can easily make you own cursor object in Game Maker.)
-
-
-Freeze the game when the form loses focus
-When checked, whenever the player brings some other form to the top (e.g.
-another application) the game freezes until the game window again gets the
-focus.
-
-
-Disable screensavers and power saving actions
-When checked (default) screensavers or power saving actions (sleep, hibernate) will not
-activate while the game is running. This is important as these might destroy certain
-graphics aspects of the game (like surfaces).

Resolution
-
-In this tab you can set the screen resolution in which your game must run.
-By default the resolution is not changed. But sometimes you want to run the
-game in a lower resolutions or you want to set the frequency of the monitor
-to make sure the timing in the game works correctly. If you want to change
-the resolution you must first check the box labeled
-Set the resolution of the screen.
-
-
-There are three things you can change. First of all there is the color depth.
-This indicates the number of bits used to represent the color for a pixel.
-Most machines now only allow for 16-bit (High Color) or 32-bit (Full Color) but
-older machines also allowed for 8-bit and sometimes 24-bit color.
-Game Maker only works correctly in 16-bit and 32-bit color. 32-bit
-color gives nicer looking images but will take more memory and processing
-time. If you want your game to run will on most older machines set the
-color depth to 16-bit. Otherwise use 32-bit or don't change it.
-
-
-Secondly there is the screen resolution, the number
-of pixels (horizontal and vertical) on the screen. Changing the
-resolution is useful when e.g. your rooms are very small. In this case
-it might help to reduce the resolution of the screen. Realize though that
-this will also effect other applications running. This can in particular
-give problems with low resolutions. So in general it is better
-to only do this when running the game in full screen mode. Game Maker
-will automatically change the resolution back to the starting situation
-once the game finishes.
-
-
-Finally you can change the refresh frequency. This indicates how many times per second
-the image on the screen is refreshed. If your room speed is larger than the frequency
-not all steps are actually visible. It works best if the frequency is a multiple of
-the room speed. (If you specify a frequency that is too high or not available the
-frequency is not changed.)
-
-
-There also is a setting here to Use synchronization to avoid tearing. This requires
-some explanation. A display is redrawn a number of times per second, depending on the
-refresh frequency. If a room is drawn halfway such a refresh, the top of the display will still
-show the old image while the bottom part shows the new image. This is called tearing. To
-avoid this you can check this option. In this case the new room image is only copied to
-the screen when the refresh is not inside the window avoiding the tearing most of the time.
-The disadvantage is that we normally have to wait till the next refresh. This means that the
-maximal number of frames is bounded by the frequency of the monitor and, when the processing
-is not fast enough, the framerate immediately drops to half that number.
-Also there can be a conflict between the internal timing of the game and the synchronization.
-If you want to do this best set the monitor frequency to e.g. 60 and also make the room speed
-either 30 or 60.

Various other options
-
-Here you can set a number of additional options. First of all you can set some default keys:
-
-
-Let <Esc> end the game
-When checked, pressing the escape key will end the game. More advanced games
-normally don't want this to happen because they might want to do some processing
-(like saving) before ending the game. In this case, uncheck this box and provide
-your own actions for the escape key.
-
-
-Treat the close button as <Esc> key
-When checked the close button of the window will generate an escape key event. When
-not checked the close button events are called instead.
-
-
-Let <F1> show the game information
-When checked pressing the F1 key will display the game information.
-
-
-Let <F4> switch between screen modes
-When checked the F4 key will switch between fullscreen and windowed mode.
-
-
-Let <F5> save the game and <F6> load a game
-When checked the player can use <F5> to store the current game situation
-and <F6> to load the last saved game. (Note that only the basic game
-data is stored. Once you use advanced features like particles or data structures
-those settings are not saved and you might have to create a save mechanism yourself.
-
-
-Let <F9> take a screenshot of a game
-When checked the player can use <F9> to create a screenshot of the game.
-This screenshot will be place in the file screenshotXXX.png in the folder where
-the game is running, where XXX is the number of the screenshot. When creating
-multiple screenshot the number is automatically increased.
-
-
-Also you can set the priority of the game process. This priority indicates how
-much processor time is allotted to the game. In normal mode the operating system
-tries to give processor time to each process that needs it in some reasonable way.
-The higher you put the priority the more time is allotted to the game, making it
-run more smoothly and faster. But other processes get less time (also Windows
-processes so even the mouse might not move anymore). Use this with care.
-
-
-Finally, you can set the version information of the game. This information is shown in the
-helptip that pops up when the user rests his mouse on the game executable. It is also
-shown when the users clicks with the right mouse button on the program and chooses
-properties and then version. If you distribute your game you best fill in this
-information.
-
-
-You should give your game a version number that consists of four parts: the major version,
-the minor version, the release number and the build number. Also you should provide the
-name of the company (you), the name of the product, the copyright information, and a
-very brief description. All these fields should be at most 64 characters long.

-
-Here you can indicate what should happen when loading a game. First of all
-you can specify your own loading image. Secondly, you can indicate whether
-to display a loading progress bar at the bottom of the image. You have three
-options here. Either no loading bar is displayed, or the default bar is
-displayed or you can specify two images: the background of the loading bar
-and the foreground. You can indicate whether the front loading bar must be

-make sure enough the image is large enough to fill the bar. (Note that
-both images must be specified in this case, not just one.)
-
-
-It is possible to indicate that the loading image must be transparent.
-In this case the left bottom pixel of the background image is used as
-transparent color. (Note that transparency from e.g. png or gif files
-is not taken into account here!)
-Also the alpha translucency can be indicated. A value
-of 0 means fully translucent. A value of 255 means fully opaque. (Both
-only work under Windows 2000, XP, or later.)
-
-
-Secondly, you can indicate here the icon that should be used for stand-alone
-games. Your icons must contain at least a 32x32 icon, but they can also
-contain larger ones. If you try to select another type of
-icon you will get a warning.
-
-
-Finally you can change the unique game id. This id is used for storing the
-highscore list and save game files. If you release a new version of your
-game and don't want to take over the old highscore list, you should change
-this number.

Speed considerations
-
-If you are making complicated games you probably want to make them run as fast as possible.
-Even though Game Maker does its best to make games run fast, a lot depends on how
-you design your game. Also, it is rather easy to make games that use large amounts of
-memory. In this page we give some hints on how to make your games faster and smaller.
-
-
-First of all, look carefully at the sprites and backgrounds you use. Animated
-sprites take a lot of memory and drawing lots of sprites takes a lot of time.
-So make your sprites as small as possible. Remove any invisible area around it
-(the command Crop in the sprite editor does that automatically). The same
-applies to background images.
-If you have a covering background, make sure you switch off the use of a
-background color.
-
-
-If you use full screen mode, make sure the size of the room
-(or window) is never larger than the screen size. Most graphics cards can
-efficiently scale images up but they are more slow in scaling images down!
-Whenever possible, switch off the cursor. It slows down the graphics.
-
-
-Also be careful with the use of many views. For each view the room is redrawn.
-
-
-Besides the graphics, there are also other aspects that influence the speed.
-Make sure you have as few instances as possible. In particular, destroy
-instances once they are no longer required (e.g. when they leave the room).
-Avoid lots of work in the step event or drawing event of instances. Often
-things do not need to be checked in each step. Interpretation of code is
-reasonably fast, but it is interpreted. Also, some functions and actions
-take a lot of time; in particular those that have to check all instances
-(like for example the bounce action).
-
-
-When you need complicated processing (for example for advanced AI), you better write
-a DLL for this in a different language and create an extension package out of this
-to import the DLL using the functions described in the page on Using DLL's.
-
-
-
-Think about where to treat the collision events. You normally have two
-options. Objects that have no collision events are treated much
-faster, so preferably treat collisions in those objects of which there are
-just a few instances.
-
-
-Be careful with using large sound files. They take a lot of memory and
-also compress badly. You might want to check your sounds and see whether
-you can sample them down.
-
-
-Finally, if you want to make a game that many people can play, make sure
-you test it on a number of different machines, in particular also older machines.

GML Language overview
-
-Game Maker contains a built-in programming language. This
-programming language gives you much more flexibility and control than the
-standard actions. This language we will refer to as GML (the Game Maker
- Language). There are a number of different places where you can type
-programs in this language. First of all, when you define scripts. A script
-is a program in GML. Secondly, when you add a code action to an event. In
-a code action you again have to provide a program in GML. Thirdly, in the
-room creation code. And finally, wherever you need to specify a value in
-an action, you can also use an expression in GML. An expression, as we
-will see below is not a complete program, but a piece of code resulting in a
-value.
-
-
-In this chapter we will describe the basic structure of programs in GML.
-When you want to use programs in GML, there are a couple of things you
-have to be careful about. First of all, for all your resources (sprites,
-objects, sounds, etc.) you must use names that start with a letter and
-only consist of letters, digits and the underscore '_' symbol. Otherwise
-you cannot refer to them from within the program. Make sure all resources
-have different names. Also be careful not to name resources self, other,
-global, or all because these have special meaning in the language. Also
-you should not use any of the keywords, indicated below.
-

A program

-A program consists of a set of instructions, called statements. A program
-must start with the symbol '{' and end with the symbol '}'. Between these
-symbols there are the statements. Statements must be separated with a ';'
-symbol. So the global structure of every program is:

Variables
-
-Like any programming language GML contains variables. Variables are memory
-locations that store information. They have a name so that you can refer
-to them. A variable in GML can store either a real number or a string.
-Variables do not need to be declared like in many other languages. There
-are a large number of built-in variables. Some are general, like
-mouse_x and mouse_y that indicate the current mouse
-position, while all others are local to the object instance for which we
-execute the program, like x and y that indicate the current position of
-the instance. A variable has a name that must start with a letter and can
-contain only letters, numbers, and the underscore symbol '_'. (The maximal
-length is 64 symbols.) When you use a new variable it is local to the
-current instance and is not known in programs for other instances (even of
-the same object). You can though refer to variables in other instances;
-see below.

Assignments
-
-An assignment stores a value in a variable. An assignment has the form:
-
-
-
<variable> = <expression>;
-
-
-An expression can be a simple value but can also be more complicated.
-Rather than assigning a value to a variable, one can also add the value to
-the current value of the variable using +=. Similar, you can subtract it
-using -=, multiply it using *=, divide it using /= ,or use bitwise
-operators using |=, &\, or ^=.

Expressions
-
-Expressions can be real numbers (e.g. 3.4), hexadecimal numbers, starting
-with a $ sign (e.g. $00FFAA), strings between single or
-double quotes (e.g. 'hello' or “hello”) or more complicated
-expressions. (Note that strings can run over multiple lines!)
-For expressions, the following binary operators exist (in
-order of priority):
-
-
* / div mod: multiplication, division, integer division, and modulo
-
-
-
-
-Note that
-value of x div y is the value of x/y rounded in the direction of zero to the nearest integer.
-The mod operator returns the remainder obtained by dividing its operands.
-In other words, x mod y = x - (x div y) * y.
-
-
-Also, the following unary operators exist:
-
-
-
!: not, turns true into false and false into true
-
-: negates the next value
-
~: negates the next value bitwise
-
-
-As values you can use numbers, variables, or functions that return a
-value. Sub-expressions can be placed between brackets. All operators work
-for real values. Comparisons also work for strings and + concatenates
-strings. (Please note that, contrary to certain languages, both arguments
-to a Boolean operation are always computed, even when the first argument
-already determines the outcome.)
-
-

-Here is an example with some assignments.

- x = 23;
- color = $FFAA00;
- str = 'hello world';
- y += 5;
- x *= y;

Extra variables
-
-You create new variables by assigning a value to them (no need to declare
-them first). If you simply use a variable name, the variable will be
-stored with the current object instance only. So don't expect to find it
-when dealing with another object (or another instance of the same object)
-later. You can also set and read variables in other objects by putting the
-object name with a dot before the variable name.
-
-
-To create global variables, that are visible to all object instances,
-precede them with the word global and a dot. So for example you
-can write:
-
-
-
-
-{
- if (global.doit)
- {
- // do something
- global.doit = false;
- }
-}
-
-
-
-
-Alternatively you can declare the variables as being global.
-This declaration looks as follows.
-
-
-
-
globalvar <varname1>,<varname2>,<varname3>, ... ;
-
-
-
-Once this declaration has been executed, the variable is always treated as global without
-the need to put the word global and a dot in front of it. It only needs to
-be declared once in a piece of code that is executed. After that in all other
-places the variable is considered as being global.
-
-
-Sometimes you want variables only within the current piece of code or
-script. In this way you avoid wasting memory and you are sure there is no
-naming conflict. It is also faster than using global variables. To achieve
-this you must declare the variables at the beginning of the piece of code
-using the keyword var. This declaration looks as follows.
-
-
-
-
var <varname1>,<varname2>,<varname3>, ... ;
-
-
-
-For example, you can write:
-
-
-
-
-{
- var xx,yy;
- xx = x+10;
- yy = y+10;
- instance_create(xx,yy,ball);

Addressing variables in other instances
-
-As described earlier, you can set variables in the current instance using
-statements like
-
-
-
x = 3;
-
-
-But in a number of cases you want to address variables in another
-instance. For example, you might want to stop the motion of all balls, or
-you might want to move the main character to a particular position, or, in
-the case of a collision, you might want to set the sprite for the other
-instance involved. This can be achieved by preceding the variable name
-with the name of an object and a dot. So for example, you can write
-
-
-
ball.speed = 0;
-
-
-This will change the speed of all instances of object ball. There are a
-number of special "objects".
-
-
-
self: The current instance for which we are executing the
-action
-
other: The other instance involved in a collision event
-
-
all: All instances
-
noone: No instance at all (sounds weird probably but it
-does come in handy as we will see later on)
-
global: Not an instance at all, but a container that stores
-global variables
-
-
-So, for example, you can use the following kind of statements:
-
-
-
-
-other.sprite_index = sprite5;
-all.speed = 0;
-global.message = 'A good result';
-global.x = ball.x;
-
-
-
-
-Now you might wonder what the last assignment does when there are multiple
-balls. Well, the first one is taken and its x value is assigned to the
-global value.
-
-
-But what if you want to set the speed of one particular ball, rather than
-all balls? This is slightly more difficult. Each instance has a unique id.
-When you put instances in a room in the designer, this instance id is
-shown when you rest the mouse on the instance. These are numbers larger
-than or equal to 100000. Such a number you can also use as the left-hand
-side of the dot. But be careful. The dot will get interpreted as the
-decimal dot in the number. To avoid this, put brackets around it. So for
-example, assuming the id of the ball is 100032, you can write:
-
-
-
(100032).speed = 0;
-
-
-When you create an instance in the program, the call returns the id. So a
-valid piece of program is
-
-
-This creates a ball and sets its speed. Note that we assigned the instance
-id to a variable and used this variable as indication in front of the dot.
-This is completely valid. Let us try to make this more precise. A dot is
-actually an operator. It takes a value as left operand and a variable
-(address) as right operand, and returns the address of this particular
-variable in the indicated object or instance. All the object names, and
-the special objects indicated above simply represent values and these can
-be dealt with like any value. For example, the following program is valid:
-
-
-The last statement should be read as follows. We take the id of the first
-flag. For the instance with that id we set the x coordinate to 12.
-
-
-Object names, the special objects, and the instance id's can also be used
-in a number of functions. They are actually treated as constants in the
-programs.

Arrays

-You can use 1- and 2-dimensional arrays in GML. Simply put the index
-between square brackets for a 1-dimensional array, and the two indices
-with a comma between them for 2-dimensional arrays. At the moment you use
-an index the array is generated. Each array runs from index 0. So be
-careful with using large indices because memory for a large array will be
-reserved. Never use negative indices. The system puts a limit of 32000 on
-each index and 1000000 on the total size. So for example you can write the
-following:
-
-
-
-
-{

Switch statement

-In a number of situations you want to let your action depend on a

-
-
-This works as follows. First the expression is executed. Next it is
-compared with the results of the different expressions after the case
-statements. The execution continues after the first case statement with
-the correct value, until a break statement is encountered. If no case
-statement has the right value, execution is continued after the default
-statement. (It is not required to have a default statement.)
-Note that multiple case
-statements can be placed for the same statement. Also, the break is not
-required. If there is no break statement the execution simply continues
-with the code for the next case statement.

-The following program takes action based on a key that is pressed.

-
-switch (keyboard_key)

Functions
-
-A function has the form of a function name, followed by zero or more
-arguments between brackets, separated by commas.
-
-
-
-
<function>(<arg1>,<arg2>,...)
-
-
-
-There are two types of functions. First of all, there is a huge collection
-of built-in functions, to control all aspects of your game. Secondly, any
-script you define in your game can be used as a function.
-
-
-Note that for a function without arguments you still need to use the
-brackets. Some functions return values and can be used in expressions.
-Others simply execute commands.
-
-
-Note that it is impossible to use a function as the lefthand side of an
-assignment. For example, you cannot write
-instance_nearest(x,y,obj).speed = 0.
-Instead you must write (instance_nearest(x,y,obj)).speed = 0.

Scripts
-
-When you create a script, you want to access the arguments passed to it
-(either when using the script action, or when calling the script as a
-function from a program (or from another, or even the same script). These
-arguments are stored in the variables argument0, argument1, ...,
-argument15. So there can be at most 16 arguments. (Note that when
-calling the script from an action, only the first 5 arguments can be
-specified.) You can also use argument[0] etc.
-
-
-Scripts can also return a value, so that they can be used in
-expressions. For this end you use the return statement:
-
-
-
-
return <expression>
-
-
-
-Execution of the script ends at the return statement!
-
-
-Example
-Here is the definition for a little script that computes the square of the
-argument:
-
-
-
-
-{
- return (argument0*argument0);
-}
-
-
-
-
-To call a script from within a piece of code, just act the same way as
-when calling functions. That is, write the script name with the argument
-values in parentheses.

With constructions
-
-As indicated before, it is possible to read and change the value of
-variables in other instances. But in a number of cases you want to do a
-lot more with other instances. For example, imagine that you want to move
-all balls 8 pixels down. You might think that this is achieved by the
-following piece of code
-
-
-
-
ball.y = ball.y + 8;
-
-
-
-But this is not correct. The right side of the assignment gets the value
-of the y-coordinate of the first ball and adds 8 to it. Next this new
-value is set as y-coordinate of all balls. So the result is that all balls
-get the same y-coordinate. The statement
-
-
-
-
ball.y += 8;
-
-
-
-will have exactly the same effect because it is simply an abbreviation of
-the first statement. So how do we achieve this? For this purpose there is
-the with statement. Its global form is
-
-
-
-
with (<expression>) <statement>
-
-
-
-<expression> indicates one or more instances. For this you can use
-an instance id, the name of an object (to indicate all instances of this
-object) or one of the special objects (all, self, other, noone).
-<statement> is now executed for each of the indicated instances, as
-if that instance is the current (self) instance. So, to move all balls 8
-pixels down, you can type.
-
-
-
-
with (ball) y += 8;
-
-
-
-If you want to execute multiple statements, put curly brackets around
-them. So for example, to move all balls to a random position, you can use
-
-
-
-
-with (ball)
-{
- x = random(room_width);
- y = random(room_height);
-}
-
-
-
-
-Note that, within the statement(s), the indicated instance has become the
-self instance. Within the statements the original self instance has become
-the other instance. So for example, to move all balls to the position of
-the current instance, you can type
-
-
-
-
-with (ball)
-{
- x = other.x;
- y = other.y;
-}
-
-
-
-
-Use of the with statement is extremely powerful. Let me give a few more
-examples. To destroy all balls you type
-
-
-
-
with (ball) instance_destroy();
-
-
-
-If a bomb explodes and you want to destroy all instances close by you can

Functions and variables in GML
-
-GML contains a large number of built-in functions and variables. With
-these you can control any part of the game. For all actions there are
-corresponding functions so you actually don't need to use any actions if
-you prefer using code. But there are many more functions and variables
-that control aspects of the game that cannot be used with actions only. So
-if you want to make advanced games you are strongly advised to read
-through the following chapters to get an overview of all that is possible.
-Please note that these variables and functions can also be used when
-providing values for actions. So even if you don't plan on using code or
-writing scripts, you will still benefit from this information.
-
-
-The following convention is used below. Variable names marked with a * are
-read-only, that is, their value cannot be changed. Variable names with
-[0..n] after them are arrays. The range of possible indices is given.

Moving around
-
-Obviously, an important aspect of games is the moving around of object instances.
-Each instance has two built-in variables x and y that indicate the position of the
-instance. (To be precise, they indicate the place where the origin of the sprite is
-placed. Position (0,0) is the top-left corner of the room. You can change the
-position of the instance by changing its x and y variables. If you want the
-object to make complicated motions this is the way to go. You typically put
-this code in the step event for the object.
-
-
-If the object moves with constant speed and direction, there is an easier
-way to do this. Each object instance has a horizontal speed (hspeed)
-and a vertical speed (vspeed). Both are indicated in pixels per step.
-A positive horizontal speed means a motion to the right, a negative horizontal
-speed mean a motion to the left. Positive vertical speed is downwards and
-negative vertical speed is upwards. So you have to set these variables only
-once (for example in the creating event) to give the object instance a constant motion.
-
-
-There is quite a different way for specifying motion, using a direction
-(in degrees 0-359), and a speed (should be non-negative). You can set
-and read these variables to specify an arbitrary motion. (Internally this
-is changed into values for hspeed and vspeed.) Also
-there is the friction and the gravity and gravity direction. Finally,
-there is the function motion_add(dir,speed) to add a motion to
-the current one.
-
-
-To be complete, each instance has the following variables and functions dealing with
-its position and motion:
-
-
-
- x
- Its x-position.
- y
- Its y-position.
- xprevious
- Its previous x-position.
- yprevious
- Its previous y-position.
- xstart
- Its starting x-position in the room.
- ystart
- Its starting y-position in the room.
- hspeed
- Horizontal component of the speed.
- vspeed
- Vertical component of the speed.
- direction
- Its current direction (0-360, counter-clockwise, 0 = to the right).
- speed
- Its current speed (pixels per step).
- friction
- Current friction (pixels per step).
- gravity
- Current amount of gravity (pixels per step).
- gravity_direction
- Direction of gravity (270 is downwards).
- motion_set(dir,speed)
- Sets the motion with the given speed in direction dir.
- motion_add(dir,speed)
- Adds the motion to the current motion (as a vector addition).
-
-
-
-There are a large number of functions available that help you in defining your motions:
-
-
-
- place_free(x,y)
- Returns whether the instance placed at position(x,y) is collision-free.
- This is typically used as a check before actually moving to the new position.
- place_empty(x,y)
- Returns whether the instance placed at position (x,y) meets nobody.
- So this function takes also non-solid instances into account.
- place_meeting(x,y,obj)
- Returns whether the instance placed at position (x,y) meets obj.
- obj can be an object in which case the function returns true is some
- instance of that object is met. It can also be an instance id, the
- special word all meaning an instance of any object, or the special word other.
- place_snapped(hsnap,vsnap)
- Returns whether the instance is aligned with the snapping values.
- move_random(hsnap,vsnap)
- Moves the instance to a free random, snapped position, like the corresponding action.
- move_snap(hsnap,vsnap)
- Snaps the instance, like the corresponding action.
- move_wrap(hor,vert,margin)
- Wraps the instance when it has left the room to the other side. hor
- indicates whether to wrap horizontaly and vert indicates whether
- to wrap vertically. margin indicates how far the origin of the
- instance must be outside the room before the wrap happens. So it is a
- margin around the room. You typically use this function in the Outside
- event.
- move_towards_point(x,y,sp)
- Moves the instances with speed sp toward position (x,y).
- move_bounce_solid(adv)
- Bounces against solid instances, like the corresponding action. adv
- indicates whether to use advance bounce, that also takes slanted walls into account.
- move_bounce_all(adv)
- Bounces against all instances, instead of just the solid ones.
- move_contact_solid(dir,maxdist)
- Moves the instance in the direction until a contact position with a solid
- object is reached. If there is no collision at the current position, the
- instance is placed just before a collision occurs. If there already is a
- collision the instance is not moved. You can specify the maximal distance
- to move (use a negative number for an arbitrary distance).
- move_contact_all(dir,maxdist)
- Same as the previous function but this time you stop at a contact with
- any object, not just solid objects.
- move_outside_solid(dir,maxdist)
- Moves the instance in the direction until it no longer lies within a solid object.
- If there is no collision at the current position the instance is not moved.
- You can specify the maximal distance to move (use a negative number for an
- arbitrary distance).
- move_outside_all(dir,maxdist)
- Same as the previous function but this time you move until outside any object,
- not just solid objects.
- distance_to_point(x,y)
- Returns the distance of the bounding box of the current instance to (x,y). (If the instance
- does not have a sprite or mask, the result of the function is undefined.)
- distance_to_object(obj)
- Returns the distance of the instance to the nearest instance of object obj. (If the instance
- or object does not have a sprite or mask, the result of the function is undefined.)
- position_empty(x,y)
- Returns whether there is nothing at position (x,y).
- position_meeting(x,y,obj)
- Returns whether at position (x,y) there is an instance obj. obj can be an object, an instance
- id, or the keywords self, other, or all.

Paths
-
-In Game Maker you can define paths and order instances to follow such paths.
-Although you can use actions for this, there are functions and variables that give
-you more flexibility:
-
-
-
- path_start(path,speed,endaction,absolute)
- Starts a path for the current instance. The path is the name of the path you
- want to start. The speed is the speed with which the path must be followed.
- A negative speed means that the instance moves backwards along the path. The
- endaction indicates what should happen when the end of the path
- is reached. The following values can be used:
-
-
- 0 : stop the path
- 1: continue from the start position (if the path is not closed we jump to the start position
- 2: continue from the current position
- 3: reverse the path, that is change the sign of the speed
-
- The argument absolute should be true or false. When true the absolute
- coordinates of the path are used. When false the path is relative to the current
- position of the instance. To be more precise, if the speed is positive, the start
- point of the path will be placed on the current position and the path is followed
- from there. When the speed is negative the end point of the path will be placed
- on the current position and the path is followed backwards from there.
- path_end()
- Ends the following of a path for the current instance.
- path_index*
- Index of the current path the instance follows. You cannot change this
- directly but must use the function above.
- path_position
- Position in the current path. 0 is the beginning of the path. 1 is the end of
- the path. The value must lie between 0 and 1.
- path_positionprevious
- Previous position in the current path. This can be used e.g. in collision events
- to set the position on the path back to the previous position.
- path_speed
- Speed (in pixels per step) with which the path must be followed. Use a
- negative speed to move backwards.
- path_orientation
- Orientation (counter-clockwise) into which the path is performed. 0 is
- the normal orientation of the path.
- path_scale
- Scale of the path. Increase to make the path larger. 1 is the default value.
- path_endaction
- The action that must be performed at the end of the path. You
- can use the values indicated above.

Motion planning
-
-Motion planning helps you to move certain instances from a given location
-to a different location while avoiding collisions with certain other instances
-(e.g. walls). Motion planning is a difficult problem. It is impossible to
-give general functions that will work properly in all situations. Also,
-computing collision free motions is a time-consuming operation. So you have
-be careful how and when you apply it. Please keep these remarks in mind when
- you use any of the following functions.
-
-
-Different forms of motion planning are provided by Game Maker.
-The simplest form lets an instance take a step towards a particular goal
-position, trying to go straight if possible but taking a different direction
-if required. These functions should be used in the step event of an instance.
-They correspond to the motion planning actions that are also available:
-
-
-
- mp_linear_step(x,y,stepsize,checkall)
- This function lets the instance take a step straight towards the indicated
- position (x,y). The size of the step is indicated by the stepsize.
- If the instance is already at the position it will not move any further.
- If checkall is true the instance will stop when it hits an instance
- of any object. If it is false it only stops when hitting a solid instance.
- Note that this function does not try to make detours if it meets an obstacle.
- It simply fails in that case. The function returns whether or not the goal position
- was reached.
- mp_linear_step_object(x,y,stepsize,obj)
- Same as the function above but this time only instances of obj are
- considered as obstacles. obj can be an object or an instance id.
- mp_potential_step(x,y,stepsize,checkall)
- Like the previous function, this function lets the instance take a step towards
- a particular position. But in this case it tries to avoid obstacles. When the
- instance would run into a solid instance (or any instance when checkall is true)
- it will change the direction of motion to try to avoid the instance and move
- around it. The approach is not guaranteed to work but in most easy cases it
- will effectively move the instance towards the goal. The function returns
- whether or not the goal was reached.
- mp_potential_step_object(x,y,stepsize,obj)
- Same as the function above but this time only instances of obj are
- considered as obstacles. obj can be an object or an instance id.
- mp_potential_settings(maxrot,rotstep,ahead,onspot)
- The previous function does its work using a number of parameters that can
- be changed using this function. Globally the method works as follows. It
- first tries to move straight towards the goal. It looks a number of steps
- ahead which can be set with the parameter ahead (default 3).
- Reducing this value means that the instance will start changing direction
- later. Increasing it means it will start changing direction earlier. If
- this check leads to a collision it starts looking at directions more to
- the left and to the right of the best direction. It does this in steps of
- size rotstep (default 10). Reducing this gives the instance more
- movement possibilities but will be slower. The parameter maxrot
- is a bit more difficult to explain. The instance has a current direction.
- maxrot (default 30) indicates how much it is allowed to change its
- current direction in a step. So even if it can move e.g. straight to the goal
- it will only do so if it does not violate this maximal change of direction.
- If you make maxrot large the instance can change a lot in each step.
- This will make it easier to find a short path but the path will be uglier.
- If you make the value smaller the path will be smoother but it might take
- longer detours (and sometimes even fail to find the goal). When no step can
- be made the behavior depends on the value of the parameter onspot.
- If onspot is true (the default value), the instance will rotate on
- its spot by the amount indicated with maxrot. If it is false it
- will not move at all. Setting it to false is useful for e.g. cars but reduces
- the chance of finding a path.
-
-
-
-Please note that the potential approach uses only local information. So it will only
-find a path if this local information is enough to determine the right direction of
-motion. For example, it will fail to find a path out of a maze (most of the time).
-
-
-The second kind of functions computes a collision-free path for the instance.
-Once this path has been computed you can assign it to the instance to move
-towards the goal. The computation of the path will take some time but after
-that the execution of the path will be fast. Of course this is only valid if
-the situation has not changed in the meantime. For example, if obstacles
-change you possibly will need to recompute the path. Again notice that these functions
-might fail.
-These functions are only available in the Pro Edition of Game Maker.
-
-
-The first two functions use the linear motion and potential field approach that
-were also used for the step functions.
-
-
-
- mp_linear_path(path,xg,yg,stepsize,checkall)
- This function computes a straight-line path for the instance from its
- current position to the position (xg,yg) using the indicated step size.
- It uses steps as in the function mp_linear_step(). The indicated
- path must already exist and will be overwritten by the new path. (See a
- later chapter on how to create and destroy paths.) The function will
- return whether a path was found. The function will stop and report failure
- if no straight path exists between start and goal. If it fails a
- path is still created that runs till the position where the instance was blocked.
- mp_linear_path_object(path,xg,yg,stepsize,obj)
- Same as the function above but this time only instances of obj are
- considered as obstacles. obj can be an object or an instance id.
- mp_potential_path(path,xg,yg,stepsize,factor,checkall)
- This function computes a path for the instance from its current position
- and orientation to the position (xg,yg) using the indicated step size
- trying to avoid collision with obstacles. It uses potential field steps,
- like in the function mp_potential_step() and also the parameters
- that can be set with mp_potential_settings(). The indicated path
- must already exist and will be overwritten by the new path. (See a later
- chapter on how to create and destroy paths.) The function will return
- whether a path was found. To avoid the function continuing to compute
- forever you need to provide a length factor larger than 1. The function
- will stop and report failure if it cannot find a path shorter than this
- factor times the distance between start and goal. A factor of 4 is normally
- good enough but if you expect long detours you might make it longer. If
- it fails a path is still created that runs in the direction of the goal
- but it will not reach it.
- mp_potential_path_object(path,xg,yg,stepsize,factor,obj)
- Same as the function above but this time only instances of obj are
- considered as obstacles. obj can be an object or an instance id.
-
-
-
-The other functions use a much more complex mechanism using a grid-based
-approach (sometimes called an A* algorithm). It will be more successful
-in finding paths (although it still might fail) and will find shorter paths
-but it required more work on your side. The global idea is as follows.
-First of all we put a grid on (the relevant part of) the room. You can
-choose to use a fine grid (which will be slower) or a coarse grid. Next,
-for all relevant objects we determine the grid cells they overlap (either
-using bounding boxes or precise checking) and mark these cells as being
-forbidden. So a cell will be marked totally forbidden, even if it only
-partially overlaps with an obstacle. Finally we specify a start and a goal
-position (which must lie in free cells) and the function computes the
-shortest path (actually close to the shortest) between these. The path
-will run between centers of free cells. So if the cells are large enough
-so that the instance placed at its center will lie completely inside
-it this will be successful. This path you can now give to an instance
-to follow.
-
-
-The grid-based approach is very powerful (and is used in many professional
-games) but it requires that you do some careful thinking. You must determine
-which area and cell size are good enough for solving the game. Also you must
-determine which objects must be avoided and whether precise checking is
-important. All these parameters strongly influence the efficiency of the approach.
-
-
-In particular the size of the cells is crucial. Remember that the cells
-must be large enough so that the moving object placed with its origin
-on the center of a cell must lie completely inside the cell. (Be careful
-about the position of the origin of the object. Also realize that you can
-shift the path if the origin of the object is not in its center!) On the
-other hand, the smaller the cells the more possible paths exist. If you
-make cells too large, openings between obstacles may get closed because
-all cells intersect an obstacle.
-
-
-The actual functions for the grid-based approach are as follows:
-
-
-
- mp_grid_create(left,top,hcells,vcells,cellwidth,cellheight)
- This function creates the grid. It returns an index that must be used in
- all other calls. You can create and maintain multiple grid structures at
- the same moment. left and top indicate the position of the top-left corner
- of the grid. hcells and vcells indicate the number of horizontal and vertical
- cells. Finally cellwidth and cellheight indicate the size of the cells.
- mp_grid_destroy(id)
- Destroys the indicated grid structure and frees its memory. Don't forget to
- call this if you don't need the structure anymore.
- mp_grid_clear_all(id)
- Mark all cells in the grid to be free.
- mp_grid_clear_cell(id,h,v)
- Clears the indicated cell. Cell 0,0 is the top left cell.
- mp_grid_clear_rectangle(id,left,top,right,bottom)
- Clears all cells that intersect the indicated rectangle (in room coordinates).
- mp_grid_add_cell(id,h,v)
- Marks the indicated cell as being forbidden. Cell 0,0 is the top left cell.
- mp_grid_add_rectangle(id,left,top,right,bottom)
- Marks all cells that intersect the indicated rectangle as being forbidden.
- mp_grid_add_instances(id,obj,prec)
- Marks all cells that intersect an instance of the indicated object as
- being forbidden. You can also use an individual instance by making obj
- the id of the instance. Also you can use the keyword all
- to indicate all instances of all objects. prec indicates whether precise
- collision checking must be used (will only work if precise checking is
- enabled for the sprite used by the instance).
- mp_grid_path(id,path,xstart,ystart,xgoal,ygoal,allowdiag)
- Computes a path through the grid. path must indicate an existing path that
- will be replaced by the computer path. xstart and ystart indicate the start
- of the path and xgoal and ygoal the goal. allowdiag indicates whether
- diagonal moves are allowed instead of just horizontal or vertical. The
- function returns whether it succeeded in finding a path. (Note that the
- path is independent of the current instance; It is a path through the g
- rid, not a path for a specific instance.)
- mp_grid_draw(id)
- This function draws the grid with green cells being free and red cells being
- forbidden. This function is slow and only provided as a debug tool.

Collision checking
-
-When planning motions or deciding on certain actions, it is often important
-to see whether there are collisions with other objects at certain places. The
-following routines can be used for this. All these have three arguments in
-common: The argument obj can be an object, the keyword all,
-or the id of an instance. The argument prec indicates whether
- the check should be precise or only based on the bounding box of the instance.
- Precise checking is only done when the sprite for the instance has the
- precise collision checking set. The argument notme can be set
- to true to indicate that the calling instance should not be checked.
- All these functions return either the id of one of the instances that
- collide, or they return a negative value when there is no collision.
-
-
-
- collision_point(x,y,obj,prec,notme)
- This function tests whether at point (x,y) there is a collision
- with entities of object obj.
- collision_rectangle(x1,y1,x2,y2,obj,prec,notme)
- This function tests whether there is a collision between the (filled)
- rectangle with the indicated opposite corners and entities of object obj.
- For example, you can use this to test whether an area is free of obstacles.
- collision_circle(xc,yc,radius,obj,prec,notme)
- This function tests whether there is a collision between the (filled)
- circle centered at position (xc,yc) with the given radius and entities
- of object obj. For example, you can use this to test whether there is
- an object close to a particular location.
- collision_ellipse(x1,y1,x2,y2,obj,prec,notme)
- This function tests whether there is a collision between the (filled)
- ellipse with the indicated opposite corners and entities of object obj.
- collision_line(x1,y1,x2,y2,obj,prec,notme)
- This function tests whether there is a collision between the line segment
- from (x1,y1) to (x2,y2) and entities of object obj. This is a powerful
- function. You can e.g. use it to test whether an instance can see another
- instance by checking whether the line segment between them intersects a wall.

Instances
-
-In the game, the basic units are the instances of the different objects. During
-game play you can change a number of aspects of these instances. Also you can
-create new instances and destroy instances. Besides the movement related
-variables discussed above and the drawing related variables discussed below,
-each instance has the following variables:
-
-
-
- object_index*
- Index of the object this is an instance of. This variable cannot be changed.
- id*
- The unique identifier for the instance (>= 100000). (Note that
- when defining rooms the id of the instance under the mouse is always indicated.)
- mask_index
- Index of the sprite used as mask for collisions. Give this a value
- of -1 to make it the same as the sprite_index.
- solid
- Whether the instance is solid. This can be changed during the game.
- persistent
- Whether the instance is persistent and will reappear when moving
- to another room. You often want to switch persistence off at certain
- moments. (For example if you go back to the first room.)
-
-
-
-There is one problem when dealing with instances. It is not so easy to identify
-individual instances. They don't have a name. When there is only one instance
-of a particular object you can use the object name but otherwise you need to
-get the id of the instance. This is a unique identifier for the instance. you
-can use it in with statements and as object identifier. Fortunately
-there are a number of variables and routines that help you locate instance id's.
-
-
-
- instance_count*
- Number of instances that currently exist in the room.
- instance_id[0..n-1]*
- The id of the particular instance. Here n is the number of instance.
-
-
-
-Note that the assignment of the instances to the instance id's changes every
-step so you cannot use values from previous steps. Also please note that instances
-that are deleted will remain in the list until the end of the step. So if you
-are also deleting instances you need to check whether the instance still exists.
-Let me give an example. Assume each unit in your game has a particular power
-and you want to locate the strongest one, you could use the following code:
-
-
-
-
-{
- maxid = -1;
- maxpower = 0;
- for (i=0; i<instance_count; i+=1)
- {
- iii = instance_id[i];
- if (instance_exists(iii))
- if (iii.object_index == unit)
- {
- if (iii.power > maxpower)
- {maxid = iii; maxpower = iii.power;}
- }
- }
-}
-
-
-
-
-After the loop maxid will contain the id of the unit with largest power. Of course, for this particular
-situation the following code would be better:
-
-
- instance_find(obj,n)
- Returns the id of the (n+1)'th instance of type obj. obj can be an object
- or the keyword all. If it does not exist, the special object noone is
- returned. Note that the assignment of the instances to the instance id's
- changes every step so you cannot use values from previous steps.
- instance_exists(obj)
- Returns whether an instance of type obj exists. obj can be an object,
- an instance id, or the keyword all.
- instance_number(obj)
- Returns the number of instances of type obj. obj can be an object or
- the keyword all.
- instance_position(x,y,obj)
- Returns the id of the instance of type obj at position (x,y). When
- multiple instances are at that position the first is returned. obj can
- be an object or the keyword all. If it does not exist, the special object
- noone is returned.
- instance_nearest(x,y,obj)
- Returns the id of the instance of type obj nearest to (x,y). obj can be an
- object or the keyword all.
- instance_furthest(x,y,obj)
- Returns the id of the instance of type obj furthest away from (x,y). obj can
- be an object or the keyword all.
- instance_place(x,y,obj)
- Returns the id of the instance of type obj met when the current instance is
- placed at position (x,y). obj can be an object or the keyword all. If it
- does not exist, the special object noone is returned.
-
-
-
-The following functions can be used for creating and destroying instances.
-
-
-
- instance_create(x,y,obj)
- Creates an instance of obj at position (x,y). The function returns
- the id of the new instance.
- instance_copy(performevent)
- Creates a copy of the current instance. The argument indicates whether
- the creation event must be executed for the copy. The function returns
- the id of the new copy.
- instance_destroy()
- Destroys the current instance.
- instance_change(obj,perf)
- Changes the instance into obj. perf indicates whether to perform the
- destroy and creation events.
- position_destroy(x,y)
- Destroys all instances whose sprite contains position (x,y).
- position_change(x,y,obj,perf)
- Changes all instances at (x,y) into obj. perf indicates whether to
- perform the destroy and creation events.

Deactivating instances
-
-Please be aware that deactivating and activating instances can sometimes lead to
-unexpected problems. So you are strongly advised not to use this feature except for
-very simple situation like the ones described below.
-The feature is mainly left in for backward compatibility.
-
-
-When you create large room, for example in platform games, with a small view,
-many instances lie outside the view. Such instances though are still active
-and will execute their events. Also when performing collision checks
-these instances are taken into account. This can cost a lot of time, which
-is often not necessary. (For example, often it is not important whether
-instances outside the view move.) To solve this problem Game Maker
-contains some functions to deactivate and activate instances. Before using
-them you must though clearly understand how they work.
-
-
-When you deactivate instances they are in some sense removed from the game.
-They are not visible anymore nor are any events executed for them. So for
-all actions and functions they don't exist anymore. This saves a lot of time
-but you have to be careful. For example, when you delete all instances of a
-particular type, deactivated instances are not deleted (because they don't
-exist). So don't think that a key a player picks up can unlock a deactivated door.
-Also persistent deactivated instances are not moved over to the next room (even
-though they are persistent). Also make sure that after you deactivate an instance that
-you no longer execute code for it. This can in particular happen when an instance
-deactivates itself. In general you better never have an instance deactivate itself.
-
-
-The most crucial mistake you can make is to deactivate the instance that is
-responsible for the activation. To avoid this some of the routines below allow
-you to insist that the calling instance should not be deactivated itself.
-
-
-Here are the available routines:
-
-
-
- instance_deactivate_all(notme)
- Deactivates all instances in the room. If notme is true the calling instance
- is not deactivated (which is normally what you want).
- instance_deactivate_object(obj)
- Deactivates all instances in the room of the given object. You can also use all
- to indicate that all instances must be deactivated or the id of an instance to
- deactivate an individual instance.
- instance_deactivate_region(left,top,width,height,inside,notme)
- Deactivates all instances in the indicated region (that is, those whose
- bounding box lies partially inside the region). If inside is false the
- instances completely outside the region are deactivated. If notme is
- true the calling instance is not deactivated (which is normally what you want).
- instance_activate_all()
- Activates all instances in the room.
- instance_activate_object(obj)
- Activates all instances in the room of the given object. You can also
- use all to indicate that all instances must be activated or the id of
- an instance to activate an individual instance.
- instance_activate_region(left,top,width,height,inside)
- Activates all instances in the indicated region. If inside is false the
- instances completely outside the region are activated.
-
-
-
-For example, to deactivate all instances outside the view and activate the ones
-inside the view, you could place the following code in the step event of the moving
-character:
-
-
-In practice you might want to use a region slightly larger than the view.

Timing
-
-Good games require careful timing of things happening. Fortunately
-Game Maker does most of the timing for you. It makes sure things
-happen at a constant rate. This rate is defined when defining the rooms.
-But you can change it using the global variable room_speed. So for example,
-you can slowly increase the speed of the game, making it more difficult,
-by adding a very small amount (like 0.001) to room_speed in every step.
-If your machine is slow the game speed might not be achieved. This can be
-checked using the variable fps that constantly monitors the actual number
-of frames per second. Finally, for some advanced timing you can use the
-variable current_time that gives the number of milliseconds since the
-computer was started. Here is the total collection of variables available
-(only the first one can be changed):
-
-
-
- room_speed
- Speed of the game in the current room (in steps per second).
- fps*
- Number of frames that are actually drawn per second.
- current_time*
- Number of milliseconds that have passed since the system was started.
- current_year*
- The current year.
- current_month*
- The current month.
- current_day*
- The current day.
- current_weekday*
- The current day of the week (1=sunday, ..., 7=saturday).
- current_hour*
- The current hour.
- current_minute*
- The current minute.
- current_second*
- The current second.
-
-
-
-Sometimes you might want to stop the game for a short while. For this, use the sleep function.
-
-
-
- sleep(numb)
- Sleeps numb milliseconds.
-
-
-
-As you should know, every instance has 12 different alarm clocks that you can
-set. To change the values (or get the values) of the different alarm clocks
-use the following variable:
-
-
-
- alarm[0..11]
- Value of the indicated alarm clock. (Note that alarm clocks only get
- updated when the alarm event for the object contains actions!)
-
-
-
-We have seen that for complex timing issues you can use the time line resource.
-Each instance can have a time line resource associated with it. The following
-variables deal with this:
-
-
-
- timeline_index
- Index of the time line associated with the instance. You can set this
- to a particular time line to use that one. Set it to -1 to stop using
- a time line for the instance. Note that this does not start the time
- line. For this use the variable timeline_running.
- timeline_position
- Current position within the time line. You can change this to skip certain
- parts or to repeat parts.
- timeline_speed
- Normally, in each step the position in the time line is increased by 1.
- You can change this amount by setting this variable to a different value.
- You can use real numbers like 0.5. If the value is larger than one, several
- moments can happen within the same time step. They will all be performed
- in the correct order, so no actions will be skipped. You can also use a negative
- value to let the time line play backwards.
- timeline_running
- Indicates whether the time line is running (true) or paused or stopped (false).
- You can change this variable to run or stop the time line.
- timeline_looping
- Indicated whether the time line is looping (true) or not (false). You can change
- this variable to switch looping on or off.

Rooms
-
-Games work in rooms. Each room has an index that is indicated by the name of the room.
-The current room is stored in variable room. You cannot assume that rooms are
-numbered in a consecutive order. So never add or subtract a number from the
-room variable. Instead use the functions and variables indicated below. So
-a typical piece of code you will use is:
-
-
-The following variables and functions exist that deal with rooms.
-
-
-
- room
- Index of the current room; can be changed to go to a different room,
- but you had better use the routines below.
- room_first*
- Index of the first room in the game.
- room_last*
- Index of the last room in the game.
- room_goto(numb)
- Goto the room with index numb.
- room_goto_previous()
- Go to the previous room.
- room_goto_next()
- Go to the next room.
- room_restart()
- Restart the current room.
- room_previous(numb)
- Return the index of the room before numb (-1 = none) but don't go there.
- room_next(numb)
- Return the index of the room after numb (-1 = none).
- game_end()
- End the game.
- game_restart()
- Restart the game.
-
-
-
-When calling one of the above functions to change the room or end or restart the game, please realize
-that this change does actually not occur at that precise moment. It only happens after the current action is
-fully executed. So the rest of the script will still be executed, and the same applies to possible
-calling scripts. However, no events are executed anymore. As this can lead to unexpected behavior you are strongly
-advised not to put any code anymore after the use of such functions.
-
-
-Rooms have a number of additional properties:
-
-
-
- room_width*
- Width of the room in pixels.
- room_height*
- Height of the room in pixels.
- room_caption
- Caption string for the room that is displayed in the caption of the window.
- room_persistent
- Whether the current room is persistent.
-
-
-
-Many games offer the player the possibility of saving the game and loading a saved game.
-In Game Maker this happens automatically when the player press <F5>
-for saving and <F6> for loading. You can also save and load games from
-within a piece of code (note that loading only takes place at the end of the
-current step).
-
-
-
- game_save(string)
- Saves the game to the file with name string.
- game_load(string)
- Loads the game from the file with name string.
-
-
-
-Please realize that only the basic game data is being saved. If for example you play
-a particular piece of music, the precise position in the music is not saved. Also changed
-resources are not saved. Other things that are not saved are the contents of data structures,
-particles, and multiplayer settings.
-
-
Transitions
-
-
-When you move from one room to another you can select a transition.
-To set the transition to the next frame you must set the
-variable called transition_kind. If you assign a value larger than 0 to it the
-corresponding transition is used for the next room transition. It only affect the next
-transition. After this the value is reset to 0, which indicates no transition.
-
-
-
- transition_kind
- Indicates the next room transition. You can use the following builtin values
-
-
- 0 = no effect
- 1 = Create from left
- 2 = Create from right
- 3 = Create from top
- 4 = Create from bottom
- 5 = Create from center
- 6 = Shift from left
- 7 = Shift from right
- 8 = Shift from top
- 9 = Shift from bottom
- 10 = Interlaced from left
- 11 = Interlaced from right
- 12 = Interlaced from top
- 13 = Interlaced from bottom
- 14 = Push from left
- 15 = Push from right
- 16 = Push from top
- 17 = Push from bottom
- 18 = Rotate to the left
- 19 = Rotate to the right
- 20 = Blend the rooms
- 21 = Fade out and in
-
- transition_steps
- Indicates the number of steps in the transition. The more steps, the longer the
- transition takes. Default is 80.
- transition_define(kind,name)
- You can actually create your own transitions. To this end you must define a script
- (possibly in an extension package) to do the transition. With this function you can
- then add the transition to the system. kind is
- the index of the transition (either a new one or an existing transitions). name is the
- name of the script. Note that the name of the script is a string!
- So there must be quotes around it.
- Note that this is really advanced stuff.
- The script must take five arguments: a surface with the image
- of the previous room, a surface with the image of the next room, the width of the
- surfaces, the height of the surfaces, and the fraction
- of the transition (between 0 and 1). It must then draw the image using the two
- surfaces.
- transition_exists(kind)
- This function returns whether a transition of the indicated kind exists.
-
-
-
-Please note that transitions do not work when using using 3d graphics. Also, room transitions in general
-do not work correctly when the sizes of the rooms (or to be more precise of the region on the screen)
-are not the same.

Score

-Other important aspects of many games are the score, the health, and the number
-of lives. Game Maker keeps track of the score in a global
-variable score and the number of lives in a global variable
-lives. You can change the score by simply changing the value of this variable.
-The same applies to health and lives. If lives is larger than 0 and becomes
-smaller than or equal to 0 the no-more-lives event is performed for all

Generating events
-
-As you know, Game Maker is completely event driven. All actions
-happen as the result of events. There are a number of different events.
-Creation and destroy events happen when an instance is created or
-destroyed. In each step, the system first handles the begin step events.
-Next it handles the alarm events, keyboard and mouse events and next the step event.
-After this the instances are set to their new positions after which
-the collision event is handled. Finally the end step events are handled after
-which the draw event is used to
-draw the instances (note that when there are multiple views the draw
-event is called multiple times in each step). You can also apply an
-event to the current instance from within a piece of code. The following
-functions exist:
-
-
-
- event_perform(type,numb)
- Performs event numb of the indicated type to the current instance.
- The following event types can be indicated:
-
-
- When there are multiple events of the given type, numb can be used to specify
- the precise event. For the event type ev_alarm numb can range from 0 to 11. For the
- ev_keyboard, ev_keypress. and ev_keyrelease
- event types you have to use the keycode for the key. For ev_mouse events you
- can use for numb the following constants:
-
- For the ev_step event type you can use the following constants for numb:
-
-
- ev_step_normal
- ev_step_begin
- ev_step_end
-
- Finally for the ev_trigger event type you should use the constants that you can
- specify when defining these events.
- event_perform_object(obj,type,numb)
- This functions works the same as the function above except that this time you can
- specify events in another object. Note that the actions in these events are applied
- to the current instance, not to instances of the given object!
- event_user(numb)
- In the other events you can also define 16 user events. These are only performed if
- you call this function. numb must lie in the range 0 to 15.
- event_inherited()
- Performs the inherited event. This only works if the instance has a parent object.
-
-
-
-You can get information about the current event being executed using the
-following read-only variables:
-
-
-
- event_type*
- Type of the current event begin executed.
- event_number*
- Number of the current event begin executed.
- event_object*
- The object index for which the current event is being executed.
- event_action*
- The index of the action that is currently being executed (0 is the first in the event, etc.).

Miscellaneous variables and functions
-
-Here are some variables and functions that deal with errors.
-
-
-
- error_occurred
- Indicates whether an error has occurred.
- error_last
- String indicating the last error message.
- show_debug_message(str)
- Shows the string in debug mode.
- debug_mode
- This read-only variable indicates whether the game is running in debug mode.
-
-
-The following variables can be used to make sure your code will work for the appropriate version and edition
-of Game Maker.
-
-
-
- gamemaker_pro
- Indicates whether the game is created with the Pro Edition.
- gamemaker_registered
- Same as gamemaker_pro
- gamemaker_version
- The version of Game Maker. This is an integer. For version 8.0 this can be
- anything between 800 and 809. For version 8.1 this will be something between
- 810 and 819, etc. So never check a particular version but better check for a range.
- This variable is not available in version before 800.
-
-
-
-The following functions exist that allow you to check whether certain variables
-exist and with which you can set variables and get their values. In all
-these functions the variable name is passed as a string!
-
-
-
- variable_global_exists(name)
- Returns whether a global variable with the given name (a string) exists.
- variable_local_exists(name)
- Returns whether a local variable with the given name (a string) exists for the current instance.
- variable_global_get(name)
- Returns the value of the global variable with the given name (a string).
- variable_global_array_get(name,ind)
- Returns the value of index ind of the global array variable with the given name (a string).

- Returns the value of index ind1,ind2 of the local 2-dimensional array
- variable with the given name (a string).
- variable_global_set(name,value)
- Sets the global variable with the given name (a string) to the given value.
- variable_global_array_set(name,ind,value)
- Sets the index ind in the global array variable with the given name (a string)
- to the given value.
- variable_global_array2_set(name,ind1,ind2,value)
- Sets the index ind1,ind2 in the global 2-dimensional array variable with the
- given name (a string) to the given value.
- variable_local_set(name,value)
- Sets the local variable with the given name (a string) to the given value.
- variable_local_array_set(name,ind,value)

- variable_local_array2_set(name,ind1,ind2,value)
- Sets the index ind1,ind2 in the local 2-dimensional array variable with
- the given name (a string) to the given value.
-
-You can also use these functions to pass variables to a script in a sort of by-reference
-way, by passing their names as strings and using the functions to change them.
-
-
-You can change the program priority using the following function:
-
-
-
- set_program_priority(priority)
- Sets the priority for the program. You can indicate a value between -3 and +3.
- A value of -3 means that the program will only run if no other process on the
- computer requires processing time, or stated differently, when all other
- processes are idle. Values of -2 and -1 are below normal, so other processes
- will get priority. 0 is the normal value. +1 and +2 give a higher priority,
- resulting possibly in higher speed and smoother game flow. But other
- processes will get much less processing time. +3 indicates real-time mode.
- In real-time mode basically all time is allotted to the game. This can
- lead to serious problems with any other applications running on the computer.
- Also keyboard events and e.g. the pressing of the close box might no longer
- be recorded by Windows. So only use this if you want all the processor time.
- Also better check carefully before using it and save the game before running.
-
-
-
-Finally, you can use the following function to set the title of the application:
-
-
-
-
- set_application_title(title)
- Sets the title of the application to the given string. The title is for example shown
- in the task bar.

User interaction
-
-There is no game without interaction with the user.
-The standard way of doing this in Game Maker is to put actions
-in mouse or keyboard events. But sometimes you need more control.
-From within a piece of code you can check whether certain keys on
-the keyboard are pressed and you can check for the position of the
-mouse and whether its buttons are pressed. Normally you check these
-aspects in the step event of some controller object and take

The keyboard
-
-For keyboard interaction, the following variables and functions exist:
-
-
-
- keyboard_lastkey
- Keycode of last key pressed. See below for keycode constants.
- You can change it, e.g. set it to 0 if you handled it.
- keyboard_key
- Keycode of current key pressed (see below; 0 if none).
- keyboard_lastchar
- Last character pressed (as string).
- keyboard_string
- String containing the last at most 1024 characters typed. This string
- will only contain the printable characters typed. It also correctly
- responds to pressing the backspace key by erasing the last character.
-
-
-
-
-Sometimes it is useful to map one key to another. For example you might want
-to allow the player to use both the arrow keys and the numpad keys. Rather
-than duplicating the actions you can map the numpad keys to the arrow keys.
-Also you might want to implement a mechanism in which the player can set
-the keys to use. For this the following functions are available:
-
-
-
- keyboard_set_map(key1,key2)
- Maps the key with keycode key1 to key2.
- keyboard_get_map(key)
- Returns the current mapping for key.
- keyboard_unset_map()
- Resets all keys to map to themselves.
-
-
-
-
-To check whether a particular key or mouse button is pressed you can use the following
-functions. This is in particular useful when multiple keys are pressed simultaneously.
-
-
-
- keyboard_check(key)
- Returns whether the key with the particular keycode is currently down.
- keyboard_check_pressed(key)
- Returns whether the key with the particular keycode was pressed since the last step.
- keyboard_check_released(key)
- Returns whether the key with the particular keycode was released since the last step.
- keyboard_check_direct(key)
- Returns whether the key with the particular keycode is pressed
- by checking the hardware directly. The result is independent of
- which application has focus. It allows for a few more checks.
- In particular you can use keycodes vk_lshift, vk_lcontrol,
- vk_lalt, vk_rshift, vk_rcontrol and vk_ralt to check
- whether the left or right shift, control or alt key is pressed.
-
-
-
-
-The following routines can be used to manipulate the keyboard state:
-
-
-
- keyboard_get_numlock()
- Returns whether the numlock is set.
- keyboard_set_numlock(on)
- Sets (true) or unsets (false) the numlock.
- keyboard_key_press(key)
- Simulates a press of the key with the indicated keycode.
- keyboard_key_release(key)
- Simulates a release of the key with the indicated keycode.
-
-
-
-
-The following constants for virtual keycodes exist:
-
-
-
- vk_nokey keycode representing that no key is pressed
- vk_anykey keycode representing that any key is pressed
- vk_left keycode for left arrow key
- vk_right keycode for right arrow key
- vk_up keycode for up arrow key
- vk_down keycode for down arrow key
- vk_enter enter key
- vk_escape escape key
- vk_space space key
- vk_shift shift key
- vk_control control key
- vk_alt alt key
- vk_backspace backspace key
- vk_tab tab key
- vk_home home key
- vk_end end key
- vk_delete delete key
- vk_insert insert key
- vk_pageup pageup key
- vk_pagedown pagedown key
- vk_pause pause/break key
- vk_printscreen printscreen/sysrq key
- vk_f1 ... vk_f12 keycodes for the function keys F1 to F12
- vk_numpad0 ... vk_numpad9 number keys on the numeric keypad
- vk_multiply multiply key on the numeric keypad
- vk_divide divide key on the numeric keypad
- vk_add add key on the numeric keypad
- vk_subtract subtract key on the numeric keypad
- vk_decimal decimal dot keys on the numeric keypad
-
-
-
-
-For the letter keys use for example ord('A'). (The capital letters.)
-For the digit keys use for example ord('5') to get the <5> key.
-The following constants can only be used in keyboard_check_direct:
-
-
-
- vk_lshift left shift key
- vk_lcontrol left control key
- vk_lalt left alt key
- vk_rshift right shift key
- vk_rcontrol right control key
- vk_ralt right alt key
-
-
-
-
-For example, assume you have an object that the user can control with the arrow
-keys you can put the following piece of code in the step event of the object:
-
-
-
-
-{
- if (keyboard_check(vk_left)) x -= 4;
- if (keyboard_check(vk_right)) x += 4;
- if (keyboard_check(vk_up)) y -= 4;
- if (keyboard_check(vk_down)) y += 4;

Game graphics
-
-An important part of a game is the graphics.
-Game Maker normally takes care of most of this and for simple games there
-is need to worry about it. But sometimes you want to take more control.
-For some aspects there are actions but from code you can control many more aspects.
-This chapter describes all variables and functions available for this and gives
-some more information about what is really happening.
-
-
-
-
-Information on game graphics can be found in the following pages:
-
-
-
-Each object has a sprite associated with it. This is either a single image or it consists
-of multiple images. For each instance of the object the program draws the corresponding
-image on the screen, with its origin (as defined in the sprite properties) at the position
-(x,y) of the instance. When there are multiple images, it cycles through the images to get
-an animation effect. There are a number of variables that affect the way the image is
-drawn. These can be used to change the effects. Each instance has the following variables:
-
-
-
- visible
- If visible is true (1) the image is drawn, otherwise it is not
- drawn. Invisible instances are still active and create collision events; only you don't
- see them. Setting the visibility to false is useful for e.g. controller objects (make them
- non-solid to avoid collision events) or hidden switches.
- sprite_index
- This is the index of the current sprite for the instance.
- You can change it to give the instance a different sprite. As value you can use the names
- of the different sprites you defined. Changing the sprite does not change the index of the
- currently visible subimage.
- sprite_width*
- Indicates the width of the sprite. This value cannot be
- changed but you might want to use it.
- sprite_height*
- Indicates the height of the sprite. This value cannot be
- changed but you might want to use it.
- sprite_xoffset*
- Indicates the horizontal offset of the sprite as defined
- in the sprite properties. This value cannot be changed but you might want to use it.
- sprite_yoffset*
- Indicates the vertical offset of the sprite as defined
- in the sprite properties. This value cannot be changed but you might want to use it.
- image_number*
- The number of subimages for the current sprite for the
- instance (cannot be changed).
- image_index
- When the image has multiple subimages the program cycles
- through them. This variable indicates the currently drawn subimage (they are numbered
- starting from 0). You can change the current image by changing this variable. The program
- will continue cycling, starting at this new index. (The value can have a fractional part.
- In this case it is always rounded down to obtain the subimage that is drawn.)
- image_speed
- The speed with which we cycle through the subimages. A value of 1 indicates that each step we
- get the next image. Smaller values will switch subimages slower, drawing each subimage multiple
- times. Larger values will skip subimages to make the motion faster. Sometimes you want a
- particular subimage to be visible and don't want the program to cycle through all of them.
- This can be achieved by setting the speed to 0 and choosing the correct subimage. For example,
- assume you have an object that can rotate and you create a sprite that has subimages for a
- number of orientations (counter-clockwise). Then, in the step event of the object you can set
-
- depth
- Normally images are drawn in the order in which the instances are
- created. You can change this by setting the image depth. The default value is 0, unless
- you set it to a different value in the object properties. The higher the value the further
- the instance is away. (You can also use negative values.) Instances with higher depth will
- lie behind instances with a lower depth. Setting the depth will guarantee that the
- instances are drawn in the order you want (e.g. the plane in front of the cloud).
- Background instances should have a high (positive) depth, and foreground instances should
- have a low (negative) depth.
- image_xscale
- A scale factor to make larger or smaller images. A value of 1 indicates the normal size.
- You must separately set the horizontal xscale and vertical yscale. Changing the scale
- also changes the values for the image width and height and influences collision events
- as you might expect. Changing the scale can be used to get a 3-D effect. You can use
- a value of -1 to mirror the sprite horizontally.
- image_yscale
- The vertical yscale. 1 is no scaling. You can use a value of -1
- to flip the sprite vertically.
- image_angle
- The angle with which the sprite is rotated. You specify this in degrees,
- counterclockwise. A value of 0 indicates no rotation.
- This variable can only be set in the Pro Edition!
- image_alpha
- Transparency (alpha) value to use when drawing the image.
- A value of 1 is the normal opaque setting; a value of 0 is completely transparent.
- image_blend
- Blending color used when drawing the sprite. A value of c_white is the default.
- When you specify a different value the image is blended with this color. This
- can be used to colorize the sprite on the fly.
- This variable can only be set in the Pro Edition!
- bbox_left*
- Left side of the bounding box of the instance in the room, as defined by its image (taking scaling into account).
- bbox_right*
- Right side of the bounding box of the instance in the room.
- bbox_top*
- Top side of the bounding box of the instance in the room.
- bbox_bottom*
- Bottom side of the bounding box of the instance in the room.

Drawing sprites and backgrounds
-
-Objects normally have a sprite associated to it that is drawn. But you can use
-the draw event to draw other things. This section and the next couple give you
-information on what is possible. First of all, there are functions to draw
-sprites and backgrounds in different ways. These give you more control over
-the appearance of the sprite. Also you can draw (parts of) backgrounds.
-
-
-
- draw_sprite(sprite,subimg,x,y)
- Draws subimage subimg (-1 = current) of
- the sprite with its origin at position (x,y).
- (Without color blending and no alpha transparency.)
- draw_sprite_stretched(sprite,subimg,x,y,w,h)
- Draws the sprite stretched so that it fills the region with top-left
- corner (x,y) and width w and height h.
- draw_sprite_tiled(sprite,subimg,x,y)
- Draws the sprite tiled so that it fills the entire room.
- (x,y) is the place where one of the sprites is drawn.
- draw_sprite_part(sprite,subimg,left,top,width,height,x,y)
- Draws the indicated part of subimage subimg (-1 = current) of the sprite
- with the top-left corner of the part at position (x,y).
-
- draw_background(back,x,y)
- Draws the background at position (x,y).
- (Without color blending and no alpha transparency.)
- draw_background_stretched(back,x,y,w,h)
- Draws the background stretched to the indicated region.
- draw_background_tiled(back,x,y)
- Draws the background tiled so that it fills the entire room.
- draw_background_part(back,left,top,width,height,x,y)
- Draws the indicated part of the background with the top-left corner of the part at position (x,y).
-
-
-
-The following functions are extended functions of the ones indicated above.
-These extended versions can only be used in the Pro Edition!
-
-
-
- draw_sprite_ext(sprite,subimg,x,y,xscale,yscale,rot,color,alpha)
- Draws the sprite scaled with factors xscale and yscale and
- rotated counterclockwise over rot degrees. color is the blending
- color (use c_white for no blending) and alpha indicates the transparency
- factor with which the images is merged with its background. A value
- of 0 makes the sprite completely transparent. A value of 1 makes it
- completely solid. This function can create great effect
- (for example partially transparent explosions).
- draw_sprite_stretched_ext(sprite,subimg,x,y,w,h,color,alpha)
- Draws the sprite stretched so that it fills the region with
- top-left corner (x,y) and width w and height h. color is the blending
- color and alpha indicates the transparency setting.
- draw_sprite_tiled_ext(sprite,subimg,x,y,xscale,yscale,color,alpha)
- Draws the sprite tiled so that it fills the entire room but now with scale factors and a
- color and transparency setting.
- draw_sprite_part_ext(sprite,subimg,left,top,width,height,x,y,xscale,yscale,color,alpha)
- Draws the indicated part of subimage subimg (-1 = current) of the sprite with
- the top-left corner of the part at position (x,y) but now with scale factors and a color and transparency setting.
- draw_sprite_general(sprite,subimg,left,top,width,height,x,y,xscale,yscale,rot,c1,c2,c3,c4,alpha)
- The most general drawing function. It draws the indicated part of subimage subimg (-1 = current)
- of the sprite with the top-left corner of the part at position (x,y) but now with scale factors, a rotation angle,
- a color for each of the four vertices (top-left, top-right, bottom-right, and bottom-left),
- and an alpha transparency value. Note that rotation takes place around the top-left corner of the part.
-
- draw_background_ext(back,x,y,xscale,yscale,rot,color,alpha)
- Draws the background scaled and rotated with blending color (use c_white for no blending)
- and transparency alpha (0-1).

- Draws the background stretched to the indicated region. color is
- the blending color and alpha indicates the transparency setting.
- draw_background_tiled_ext(back,x,y,xscale,yscale,color,alpha)

Drawing shapes
-
-There is a whole collection of functions available to draw different shapes.
-Also there are functions to draw text (see next section). You can only use
-these in the drawing event of an object; these functions in general don't
-make any sense anywhere else in code. Realize that collisions between
-instances are determined by their sprites (or masks) and not by what
-you actually draw. The following drawing functions exist that can be
-used to draw basic shapes.
-
-
-
- draw_clear(col)
- Clears the entire room in the given color (no alpha blending).
- draw_clear_alpha(col,alpha)
- Clears the entire room in the given color and alpha value (in particular useful for surfaces).
- draw_point(x,y)
- Draws a point at (x,y) in the current color.
- draw_line(x1,y1,x2,y2)
- Draws a line from (x1,y1) to (x2,y2).
- draw_line_width(x1,y1,x2,y2,w)
- Draws a line from (x1,y1) to (x2,y2) with width w.
- draw_rectangle(x1,y1,x2,y2,outline)
- Draws a rectangle. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_roundrect(x1,y1,x2,y2,outline)
- Draws a rounded rectangle. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_triangle(x1,y1,x2,y2,x3,y3,outline)
- Draws a triangle. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_circle(x,y,r,outline)
- Draws a circle at (x,y) with radius r. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_ellipse(x1,y1,x2,y2,outline)
- Draws an ellipse. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_set_circle_precision(precision)
- Sets the precision with which circles are drawn, that is, the number
- of segments they consist of. The precision must lie between 4 and 64
- and must be dividable by 4. This is also used for drawing ellipses and
- rounded rectangles.
- draw_arrow(x1,y1,x2,y2,size)
- Draws an arrow from (x1,y1) to (x2,y2).
- size indicates the size of the arrow in pixels.
- draw_button(x1,y1,x2,y2,up)
- Draws a button, up indicates whether up (1) or down (0).
- draw_path(path,x,y,absolute)
- With this function you can draw the indicated
- path in the room with its start at position (x,y). If absolute is true the path is drawn
- at the position where it was defined and the values of x and y are ignored.
-draw_healthbar(x1,y1,x2,y2,amount,backcol,mincol,maxcol,direction,showback,showborder)
- With this function you can draw a healthbar (or any other bar that indicates some value, like
- e.g. the damage). The arguments x1, y1, x2 and y2 indicate the total area for the bar.
- amount indicates the percentage of the bar that must be filled (must lie between 0 and
- 100). backcol is the color of the background for the bar. mincol and maxcol indicate the
- color when the amount is 0 and 100 respectively. For an amount in between the color is
- interpolated. So you can easily make a bar that goes e.g. from green to red. The direction
- is the direction in which the bar is drawn. 0 indicates that the bar is anchored at the
- left, 1 at the right, 2 at the top and 3 at the bottom. Finally showback indicates whether
- a background box must be shown and showborder indicated whether the box and bar should
- have a black border line.
-
-
-
-
-Most of the above functions use the color and alpha setting that
-can be changed with following functions.
-
-
-
- draw_set_color(col)
- Sets the drawing color to be used from now on for drawing primitives.
- draw_set_alpha(alpha)
- Sets the alpha transparency value to be used from now on for drawing
- primitives. Should lie in the range 0-1. 0 is fully transparent, 1 is fully opaque.
- draw_get_color()
- Returns the drawing color used for drawing primitives.
- draw_get_alpha()
- Returns the alpha value used for drawing primitives.
-
-
-
-
-A whole range of predefined colors is available:
-
-
-
-The following functions can help you to create the colors you want.
-
-
-
- make_color_rgb(red,green,blue)
- Returns a color with the indicated red,
- green, and blue components, where red, green and blue must be values between 0 and 255.
- make_color_hsv(hue,saturation,value)
- Returns a color with the
- indicated hue, saturation and value components (each between 0 and 255).
- color_get_red(col)
- Returns the red component of the color.

- Returns the green component of the color.
- color_get_blue(col)
- Returns the blue component of the color.
- color_get_hue(col)
- Returns the hue component of the color.
- color_get_saturation(col)
- Returns the saturation component of the color.
- color_get_value(col)
- Returns the value component of the color.
- merge_color(col1,col2,amount)
- Returns a merged color of col1 and col2.
- The merging is determined by amount. A value of 0 corresponds to col1, a value of 1 to
- col2, and values in between to merged values.
-
-
-
-
-The following miscellaneous functions exist.
-
-
-
- draw_getpixel(x,y)
- Returns the color of the pixel corresponding to position (x,y) in the room. This is
- not very fast, so use with care.
- screen_save(fname)
- Saves a png image of the screen in the given

Fonts and text
-
-In games you sometimes need to draw texts. To draw a text you have to specify the
-font to use. Fonts can be defined by creating font resources (either in the
-Game Maker program or using the functions to create resources). There
-are different functions to draw texts in different way. In each function you
-specify the position of the text on the screen. There are two functions to
-set the horizontal and vertical alignment of the text with respect to that
-position.
-
-
-For text drawing the following functions exist:
-
-
-
- draw_set_font(font)
- Sets the font that will be used
- when drawing text. Use -1 to set the default font (Arial 12).
- draw_set_halign(halign)
- Sets the horizontal alignment
- used when drawing text. Choose one of the following constants as values:
-
-
- fa_left
- fa_center
- fa_right
-
-
-
- draw_set_valign(valign)
- Sets the vertical alignment
- used when drawing text. Choose one of the following constants as values:
-
-
- fa_top
- fa_middle
- fa_bottom
-
-
-
- draw_text(x,y,string)
- Draws the string at position (x,y), using the drawing color and alpha. A # symbol or
- carriage return chr(13) or linefeed chr(10) are interpreted as newline characters. In this
- way you can draw multi-line texts. (Use \# to get the # symbol itself.)
- draw_text_ext(x,y,string,sep,w)
- Similar to the previous routine but you
- can specify two more things. First of all, sep indicates the separation distance between
- the lines of text in a multiline text. Use -1 to get the default distance. Use w to
- indicate the width of the text in pixels. Lines that are longer than this width are split-
- up at spaces or - signs. Use -1 to not split up lines.
- string_width(string)
- Width of the string in the current font as it would be
- drawn using the draw_text() function.
- Can be used for precisely positioning graphics.
- string_height(string)
- Height of the string in the current font as it
- would be drawn using the draw_text() function.
- string_width_ext(string,sep,w)
- Width of the string in the current font as it would be drawn using
- the draw_text_ext() function. Can be used for precisely
- positioning graphics.
- string_height_ext(string,sep,w)
- Height of the string in the current font
- as it would be drawn using the draw_text_ext() function.
-
-
-
-The following routines allow you to draw scaled and rotated text and also to
-use gradient colors on texts. These functions are only available in
-the Pro Edition!
-
-
-
- draw_text_transformed(x,y,string,xscale,yscale,angle)
- Draws the string at
- position (x,y) in the same way as above, but scale it horizontally and vertically
- with the indicated factors and rotate it counter-clockwise over angle degrees.
- draw_text_ext_transformed(x,y,string,sep,w,xscale,yscale,angle)
- Combines the function draw_text_ext and draw_text_transformed.
- It makes it possible to draw a multi-line text rotated and scaled.
- draw_text_color(x,y,string,c1,c2,c3,c4,alpha)
- Draws the string at position (x,y) like above. The four colors specify
- the colors of the top-left, top-right, bottom-right, and bottom-left corner
- of the text. alpha is the alpha transparency to be used (0-1).
- draw_text_ext_color(x,y,string,sep,w,c1,c2,c3,c4,alpha)
- Similar to draw_text_ext() but with colored vertices.
- draw_text_transformed_color(x,y,string,xscale,yscale,angle,c1,c2,c3,c4,alpha)
- Similar to draw_text_transformed() but with colored vertices.
- draw_text_ext_transformed_color(x,y,string,sep,w,xscale,yscale,angle,c1,c2,c3,c4,alpha)
- Similar to draw_text_ext_transformed() but with colored vertices.

Advanced drawing functions
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Above, a number of basic drawing functions have been described. Here you find a number of additional
-functions that offer you a lot more possibilities. First of all there are functions to draw shapes
-with gradient colors. Secondly there are functions to draw more general polygons, and finally there
-is the possibility to draw texture mapped polygons.
-
-
-The following extended versions of the basic drawing functions exist. each of them gets extra color
-parameters that are used the determine the color at different vertices. The standard drawing color is
-not used in these functions.
-
-
-
- draw_point_color(x,y,col1)
- Draws a point at (x,y) in the given color.
- draw_line_color(x1,y1,x2,y2,col1,col2)
- Draws a line from (x1,y1) to (x2,y2), interpolating the color
- between col1 and col2.
- draw_line_width_color(x1,y1,x2,y2,w,col1,col2)
- Draws a line from (x1,y1) to (x2,y2) with width w interpolating the color
- between col1 and col2.
- draw_rectangle_color(x1,y1,x2,y2,col1,col2,col3,col4,outline)
- Draws a rectangle. The four colors
- indicated the colors at the top-left, top-right, bottom-right, and bottom-left vertex. outline
- indicates whether only the outline must be drawn (true) or it should be filled (false).
- draw_roundrect_color(x1,y1,x2,y2,col1,col2,outline)
- Draws a rounded rectangle. col1 is the color in the
- middle and col2 the color at the boundary. outline indicates whether only the outline must be drawn
- (true) or it should be filled (false).
- draw_triangle_color(x1,y1,x2,y2,x3,y3,col1,col2,col3,outline)
- Draws a triangle. The three colors are
- the colors of the three vertices which is interpolated over the triangle. outline indicates whether
- only the outline must be drawn (true) or it should be filled (false).
- draw_circle_color(x,y,r,col1,col2,outline)
- Draws a circle at (x,y) with radius r. col1 is the color in
- the middle and col2 the color at the boundary. outline indicates whether only the outline must be
- drawn (true) or it should be filled (false).
- draw_ellipse_color(x1,y1,x2,y2,col1,col2,outline)
- Draws an ellipse. col1 is the color in the middle and
- col2 the color at the boundary. outline indicates whether only the outline must be drawn (true) or it
- should be filled (false).
-
-
-
-
-You can also draw larger primitives. This works slightly different. You begin by specifying the
-primitive you want to draw. Next you specify the vertices for it, and finally you end the primitive,
-at which moment it is drawn. There are six types of primitives:
-
-
-
- pr_pointlist
- The vertices are a set of points.
- pr_linelist
- The vertices are a set of line segments. Each pair of vertices forms a line segment. So
- there must be an even set of vertices.
- pr_linestrip
- The vertices form a polyline with the first connected to the second, the second to the
- third, etc. The last one is not connected to the first one. You have to specify an extra copy of the
- first vertex for this.
- pr_trianglelist
- The vertices are a set of triangles. Each triple of vertices forms a triangle. So the
- number of vertices must be a multiple of 3.
- pr_trianglestrip
- The vertices again form triangles but this time it works slightly different. The
- first three form the first triangle. The last two of these vertices, together with the next vertex,
- form the second triangle, etc. So each new vertex specifies a new triangle, connected to the previous
- one.
- pr_trianglefan
- Similar to a triangle list but this time the first vertex is part of all the
- triangles. Again, each new vertex specifies a new triangle, connected to the previous vertex and the
- first vertex.
-
-
-
-
-The following functions exist for drawing primitives
-
-
-
- draw_primitive_begin(kind)
- Start a primitive of the indicated kind.
- draw_vertex(x,y)
- Add vertex (x,y) to the primitive, using the color and alpha value set before.
- draw_vertex_color(x,y,col,alpha)
- Add vertex (x,y) to the primitive, with its own color and alpha
- value. This allows you to create primitives with smoothly changing color and alpha values.
- draw_primitive_end()
- End the description of the primitive. This function actually draws it.
-
-
-
-
-Finally, it is possible to draw primitives using sprites or backgrounds as textures. When using a
-texture the image is placed on the primitive, reshaping it to fit the primitive. Textures are used to
-add detail to primitives, e.g. a brick wall. To use textures you first must obtain the id of the
-texture you want to use. For this the following functions exist:
-
-
-
- sprite_get_texture(spr,subimg)
- Returns the id of the texture corresponding to subimage subimg of the
- indicated sprite.
- background_get_texture(back)
- Returns the id of the texture corresponding to the indicated background.
-
-
-
-
-A selected texture might not yet be in video memory. The system will put it there once you need it
-but sometimes you want to decide this yourself. For this the following two functions exist:
-
-
-
- texture_preload(texid)
- Puts the texture immediately into video memory.
- texture_set_priority(texid,prio)
- When there is too little video memory some will be removed
- temporarily to make room for others that are needed. The ones with lowest priority are removed first.
- Default, all have priority 0 but you can change the priority here. (Use positive values!)
-
-
-
-
-To add textures to primitives you must specify which parts of the textures must be put where on the
-primitive. Positions in the texture are indicated with values between 0 and 1 but there is a problem
-here. Sizes of textures must be powers of 2 (so e.g. 32x32 or 64x64). If you want to use sprites or
-background as textures you better make sure they have such a size. If not, the test will be blank. To
-find out which part of the texture is actually used you can use the following two functions. They
-return a value between 0 and 1 that indicates the width or height of the actual part of the texture
-being used. Specifying this value as texture coordinate will indicate the right or bottom side of the
-texture.
-
-
-
- texture_get_width(texid)
- Returns the width of the texture with the given id. The width lies in the
- range 0-1.
- texture_get_height(texid)
- Returns the height of the texture with the given id. The height lies in the
- range 0-1.
-
-
-
-
-To draw textured primitives you use the following functions:
-
-
-
- draw_primitive_begin_texture(kind,texid)
- Start a primitive of the indicated kind with the given texture.
- draw_vertex_texture(x,y,xtex,ytex)
- Add vertex (x,y) to the primitive with position (xtex,ytex) in the
- texture, blending with the color and alpha value set before. xtex and ytex
- should normally lie between 0 and 1 but also larger values can be used,
- leading to a repetition of the texture (see below).
- draw_vertex_texture_color(x,y,xtex,ytex,col,alpha)
- Add vertex (x,y) to the primitive with position
- (xtex,ytex) in the texture, blending with its own color and alpha value.
- draw_primitive_end()
- End the description of the primitive. This function actually draws it.
-
-
-
-There are three functions that influence how textures are drawn:
-
-
-
- texture_set_interpolation(linear)
- Indicates whether to use linear interpolation (true) or pick the
- nearest pixel (false). Linear interpolation gives smoother textures but can also be a bit blurry and
- sometimes costs extra time. This setting also influence the drawing of sprites and background.
- Default is false. (This can also be changed in the global game settings.)
- texture_set_blending(blend)
- Indicates whether to use blending with colors and alpha values. Switching
- this off might be faster on old hardware. This setting also influence the drawing of sprites and
- background. Default is true.
- texture_set_repeat(repeat)
- Indicates whether to use repeat the texture. This works as follows. As
- indicated above texture coordinates lie in the range 0-1. If you specify a value larger than 1,
- default the rest is not drawn. By setting repeat to true the texture is repeated. Note that sprites
- and backgrounds are always drawn without repeating. So once you draw a sprite of background this
- value is reset to false. Default is false.
-
-
-
-There are two more function that are not only useful for drawing textures. Normally primitives are
-blended with the background using the alpha value. You can actually indicate how this must happen.
-Besides the normal mode it is possible to indicate that the new color must be added to the
-existing color or subtracted from the existing color. This can be used to create e.g. spot
-lights or shadows. Also it is possible to sort of take the maximum of the new and existing color.
-This can avoid certain saturation effects that you can get with adding.
-Note that both subtracting and maximum do not take the alpha value fully into
-account. (DirectX does not allow this.) So you better make sure the outside area is black.
-There are two functions. The first one only gives you the four options described
-above. The second function gives you a lot more possibilities. You should
-experiment a bit with the settings. If used effectively they
-can be used to create e.g. interesting explosion or halo effects.
-
-
-
- draw_set_blend_mode(mode)
- Indicates what blend mode to use. The following values are possible: bm_normal,
- bm_add, bm_subtract, and bm_max. Don't forget to reset the
- mode to normal after use because otherwise also other sprites and even the backgrounds
- are drawn with the new blend mode.
- draw_set_blend_mode_ext(src,dest)
- Indicates what blend mode to use for both the source and destination color. The new color
- is some factor times the source and another factor times the destination. These factors
- are set with this function. To understand this, the source and destination both have
- a red, green, blue, and alpha component. So the source is (Rs, Gs, Bs, As) and
- the destination is (Rd, Gd, Bd, Ad). All are considered to lie between 0 and 1. The blend
- factors you can choose for source and destination are:
-
-
bm_zero: Blend factor is (0, 0, 0, 0).
-
bm_one: Blend factor is (1, 1, 1, 1).
-
bm_src_color: Blend factor is (Rs, Gs, Bs, As).
-
bm_inv_src_color: Blend factor is (1–Rs, 1–Gs, 1–Bs, 1–As).
-
bm_src_alpha: Blend factor is (As, As, As, As).
-
bm_inv_src_alpha: Blend factor is (1–As, 1–As, 1–As, 1–As).
-
bm_dest_alpha: Blend factor is (Ad, Ad, Ad, Ad).
-
bm_inv_dest_alpha: Blend factor is (1–Ad, 1–Ad, 1–Ad, 1–Ad).
-
bm_dest_color: Blend factor is (Rd, Gd, Bd, Ad).
-
bm_inv_dest_color: Blend factor is (1–Rd, 1–Gd, 1–Bd, 1–Ad).
-
bm_src_alpha_sat: Blend factor is (f, f, f, 1); f = min(As, 1–Ad).
-
- For example, the normal blending mode sets the source blending to bm_src_alpha and
- the destination blending to bm_inv_src_alpha. Don't forget to reset the
- mode to normal after use because otherwise also other sprites and even the backgrounds
- are drawn with the new blend mode.
-
-
-
-
-Drawing texture primitives is a bit of work but can lead to great results. You can even use it to
-make fake 3D games.

Drawing Surfaces
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-In certain situations you might want to paint not directly on the screen but on a canvas that
-can then later be used to paint things on the screen. Such a canvas is called a surface.
-For example, you want to let the user draw on the screen. The paint should not
-be drawn on the screen (because it will be removed each next
-step), but instead you want to draw it on a separate surface that is copied onto the
-screen in each step. Or you want to use a texture that changes over time.
-
-
-Surfaces make this all possible. They are actually rather simple to use. You first create a
-surface. Next you indicate that further drawing should happen on this surface. From that moment
-on all drawing functions operate on the surface. Once you are done you reset the drawing target
-and further drawing happens on the screen again. You can draw the surface on the screen in
-many different ways or use it as a texture. There are though a few things you must be aware
-of. See the remarks at the end.
-
-
-The following functions exist to deal with surfaces
-
-
- surface_create(w,h)
- Creates a surface of the indicated width and height. Returns the id
- of the surface, which must be used in all further calls. Note that
- the surface will not be cleared. This is the responsibility of the
- user. (Set it as a target and call the appropriate clear function.)
- surface_free(id)
- Frees the memory used by the surface.
- surface_exists(id)
- Returns whether the surface with the indicated id exists.
-
- surface_get_width(id)
- Returns the width of the surface.
- surface_get_height(id)
- Returns the height of the surface.
- surface_get_texture(id)
- Returns the texture corresponding to the surface. This can be used to
- draw textured objects with the image of the surface.
-
- surface_set_target(id)
- Sets the indicated surface as the drawing target. All subsequent drawing
- happens on this surface. It resets the projection to simply cover the surface.
- surface_reset_target()
- Resets the drawing target to the normal screen.
-
- surface_getpixel(id,x,y)
- Returns the color of the pixel corresponding to position (x,y) in the surface. This is
- not very fast, so use with care.
- surface_save(id,fname)
- Saves a png image of the surface in the given
- filename. Useful for making screenshots.
- surface_save_part(id,fname,x,y,w,h)
- Saves part of the surface in the given png filename.
-
- draw_surface(id,x,y)
- Draws the surface at position (x,y).
- (Without color blending and no alpha transparency.)
- draw_surface_stretched(id,x,y,w,h)
- Draws the surface stretched to the indicated region.
- draw_surface_tiled(id,x,y)
- Draws the surface tiled so that it fills the entire room.
- draw_surface_part(id,left,top,width,height,x,y)
- Draws the indicated part of the surface with its origin at position (x,y).
- draw_surface_ext(id,x,y,xscale,yscale,rot,color,alpha)
- Draws the surface scaled and rotated with blending color (use c_white for no blending)
- and transparency alpha (0-1).
- draw_surface_stretched_ext(id,x,y,w,h,color,alpha)
- Draws the surface stretched to the indicated region. color is
- the blending color and alpha indicates the transparency setting.
- draw_surface_tiled_ext(id,x,y,xscale,yscale,color,alpha)
- Draws the surface tiled so that it fills the entire room but now
- with scale factors and a color and transparency setting.
- draw_surface_part_ext(id,left,top,width,height,x,y,xscale,yscale,color,alpha)
- Draws the indicated part of the surface with its origin at position (x,y) but now
- with scale factors and a color and transparency setting.
- draw_surface_general(id,left,top,width,height,x,y,xscale,yscale,rot,c1,c2,c3,c4,alpha)
- The most general drawing function. It draws the indicated part
- of the surface with its origin at position (x,y) but now with scale factors, a rotation angle,
- a color for each of the four vertices (top-left, top-right, bottom-right, and bottom-left),
- and an alpha transparency value.
-
- surface_copy(destination,x,y,source)
- Copies the source surface at position (x,y) in the destination surface.
- (Without any form of blending.)
- surface_copy_part(destination,x,y,source,xs,ys,ws,hs)
- Copies the indicated part of the source surface at position (x,y) in the destination surface.
- (Without any form of blending.)
-
-
-
-Note that there are no functions to copy part of the screen to a surface. (This is impossible due to
-possible format differences between the screen and the surfaces.) If this is required you must set
-a surface as render target and next draw the room. You can then use the surface copying routines to get
-parts of it.
-
-
-Note that you can also create sprites and backgrounds from surfaces. See the section on changing resources
-for more information.
-
-
-Some care must be taken when using these functions. In particular please notice the following:
-
-
-
You should never change the drawing target while you are actually drawing
- on the screen, that is, never use it in drawing events. This will cause serious
- problems with the projection and viewport.
-
Surfaces do not work correctly with 3D mode. You can use them while not in 3D mode (by calling d3d_end()
- before using them), but once you start 3D mode again the surfaces will be destroyed.
-
For reasons of speed, the surface is maintained in videomemory only.
- As a result, you might loose the surface when e.g. the screen resolution
- changes or the screensaver pops up.
-
Surfaces will not be saved when saving a game.

Tiles
-
-As you should know you can add tiles to rooms. A tile is a part of a background resource.
-Tiles are just visible images. They do not react to events and they do not generate
-collisions. As a result, tiles are handled a lot faster than objects. Anything that does
-not need events or collisions can best be done through tiles. Also, often one better uses
-a tile for the nice graphics while a simple object is used to generate the collision
-events.
-
-
-You actually have more control over tiles than you might think. You can add them when
-designing the room but you can also add them during the running of the game. You can
-change their position, and even scale them or make them partially transparent. A tile has
-the following properties:
-
-
-
background. The background resource from which the tile is taken.
-
left, top, width, height. The part of the background that is used.
-
x,y. The position of the top left corner of the tile in the room.
-
depth. The depth of the tile. You can choose any depth you like,
- making tiles appear between object instances.
-
visible. Whether the tile is visible.
-
xscale, yscale. Each tile can be drawn scaled (default is 1).
-
blend. A blending color used when drawing the tile.
-
alpha. An alpha value indicating tile transparency. 1 = not
- transparent, 0 = fully transparent.
-
-
-To change the properties of a particular tile you need to know its id. When you add tiles
-when creating rooms the id is shown in the information bar at the bottom. There is also a
-function to find the id of a tile at a particular position.
-
-
-The following functions exist that deal with tiles:
-
-
-
- tile_add(background,left,top,width,height,x,y,depth)
- Adds a new tile to the room with the indicated values
- (see above for their meaning). The function returns the
- id of the tile that can be used later on.
- tile_delete(id)
- Deletes the tile with the given id.
- tile_exists(id)
- Returns whether a tile with the given id exists.
-
- tile_get_x(id)
- Returns the x-position of the tile with the given id.
- tile_get_y(id)
- Returns the y-position of the tile with the given id.
- tile_get_left(id)
- Returns the left value of the tile with the given id.
- tile_get_top(id)
- Returns the top value of the tile with the given id.
- tile_get_width(id)
- Returns the width of the tile with the given id.
- tile_get_height(id)
- Returns the height of the tile with the given id.
- tile_get_depth(id)
- Returns the depth of the tile with the given id.
- tile_get_visible(id)
- Returns whether the tile with the given id is visible.
- tile_get_xscale(id)
- Returns the xscale of the tile with the given id.
- tile_get_yscale(id)
- Returns the yscale of the tile with the given id.
- tile_get_background(id)
- Returns the background of the tile with the given id.
- tile_get_blend(id)
- Returns the blending color of the tile with the given id.
- tile_get_alpha(id)
- Returns the alpha value of the tile with the given id.
-
- tile_set_position(id,x,y)
- Sets the position of the tile with the given id.
- tile_set_region(id,left,top,width,height)
- Sets the region of the tile with the given id in its background.
- tile_set_background(id,background)
- Sets the background for the tile with the given id.
- tile_set_visible(id,visible)
- Sets whether the tile with the given id is visible.
- tile_set_depth(id,depth)
- Sets the depth of the tile with the given id.
- tile_set_scale(id,xscale,yscale)
- Sets the scaling of the tile with the given id.
- tile_set_blend(id,color)
- Sets the blending color of the tile with the given id.
- Only available in the Pro Edition!
- tile_set_alpha(id,alpha)
- Sets the alpha value of the tile with the given id.
-
-
-
-
-The following functions deal with layers of tiles, that is, collections of tiles at the
-same depth.
-
-
-
- tile_layer_hide(depth)
- Hides all tiles at the indicated depth layer.
- tile_layer_show(depth)
- Shows all tiles at the indicated depth layer.
- tile_layer_delete(depth)
- Deletes all tiles at the indicated depth layer.
- tile_layer_shift(depth,x,y)
- Shifts all tiles at the indicated depth layer
- over the vector x,y. Can be used to create scrolling layers of tiles.
- tile_layer_find(depth,x,y)
- Returns the id of the tile with the given depth at position (x,y).
- When no tile exists at the position -1 is returned. When multiple
- tiles with the given depth exist at the position the first one is returned.
- tile_layer_delete_at(depth,x,y)
- Deletes the tile with the given depth at position (x,y).
- When multiple tiles with the given depth exist at the position they are
- all deleted.
- tile_layer_depth(depth,newdepth)
- Changes the depth of all tiles at the indicated depth to the
- new depth. With this function you can move whole tile layers to a
- new depth.

The display
-
-The display represents the whole area on the monitor. It has a size
-(typically 1024x768, or 1280x1024), a color depth, that is, the number
-of bits that are used to represent a single pixel (typically 16 = High Color
-or 32 = Full Color) and a refresh frequency, that is, the number of times
-per second the display is refreshed (typically between 60 and 120).
-These settings can normally be changed though the display properties.
-For games though, in particular when they run in full-screen mode,
-it is important to be able to change these settings. All these
-settings can be initialized for the game in the Game Settings.
-For use during game play the following functions exist. Note
-though that changing the settings during game play will result
-in a time delay as things has to be rebuilt.

The window
-
-The actual game happens in a window. This window has a number of properties,
-like whether it has a border, whether it is full screen, etc. Normally
-these are set in the Game Settings. But you can change then during
-the game. The following functions exist for this:
-
-
-
- window_set_visible(visible)
- Sets whether the game window is visible. Clearly you normally
- want the window to remain visible during the whole game. The program
- will not receive keyboard events when the window is invisible.
- window_get_visible()
- Returns whether the game window is visible.
- window_set_fullscreen(full)
- Sets whether the window is shown in full screen mode.
- window_get_fullscreen()
- Returns whether the window is shown in full screen mode.
- window_set_showborder(show)
- Sets whether the border around the window is shown.
- (In full screen mode it is never shown.)
- window_get_showborder()
- Returns whether the border around the window is shown in windowed mode.
- window_set_showicons(show)
- Sets whether the border icons (iconize, maximize, close) are shown.
- (In full screen mode these are never shown.)
- window_get_showicons()
- Returns whether the border icons are shown in windowed mode.
- window_set_stayontop(stay)
- Sets whether the window must always stay on top of other windows.
- window_get_stayontop()
- Returns whether the window always stays on top of other windows.
- window_set_sizeable(sizeable)
- Sets whether the window is sizeable by the player. (The player can
- only size it when the border is shown and the window is not in full screen mode.)
- window_get_sizeable()
- Returns whether the window is sizeable by the player.
- window_set_caption(caption)
- Sets the caption string for the window. Normally you specify this
- when defining the room and it can be changed using the variable
- room_caption. So this function is normally not useful, unless you
- draw the room yourself rather than letting Game Maker do it.
- The caption is only visible when the window has a border and
- when it is not in full screen mode.
- window_get_caption()
- Returns the window caption.
- window_set_cursor(curs)
- Sets the mouse cursor used in the window. You can use the following constant:
-
- In particular, to hide the mouse cursor, use cr_none as value.
- window_get_cursor()
- Returns the cursor used in the window.
- window_set_color(color)
- Sets the color of the part of the window that is not
- used for displaying the room.
- window_get_color()
- Returns the window color.
- window_set_region_scale(scale,adaptwindow)
- If the window is larger than the actual room normally the room
- is displayed in a region centered in the window. It is though
- possible to indicate that it must be scaled to fill the whole
- or part of the window. A value of 1 is no scaling. If you use
- a value of 0 the region will be scaled to fill the whole window.
- If you set it to a negative value it will be scaled to the
- maximal size inside the window while maintaining the aspect
- ratio (this is often what you want). adaptwindow
- indicates whether the window size must be adapted if the
- scaled room does not fit in. Adapting the window is only
- effective when the scale factor is positive.
- window_get_region_scale()
- Returns the scale factor for the drawing region.
-
-
-
-
-The window has a position on the screen and a size. (When we talk about
-position and size we always mean the client part of the window without
-the borders.) You can change these although you hardly ever do from
-within your game. Normally they are determined automatically or by
-the player. The following functions can be used to change the window
-position and size. Note that these functions deal with the windowed
-mode. If the window is in full screen mode they can still be used
-but will only have effect when switching full screen mode off.
-
-
-
- window_set_position(x,y)
- Sets the position of the (client part of the) window to the indicated position.
- window_set_size(w,h)
- Sets the size of the (client part of the) window to the indicated size.
- Note that is the indicated size is too small to fit the drawing region
- it is kept large enough for the region to fit it.
- window_set_rectangle(x,y,w,h)
- Sets the position and size of the window rectangle.
- (Does both previous routines in one step.)
- window_center()
- Centers the window on the screen.
- window_default()
- Gives the window the default size and position (centered) on the screen.
- window_get_x()
- Returns the current x-coordinate of the window.
- window_get_y()
- Returns the current y-coordinate of the window.
- window_get_width()
- Returns the current width of the window.
- window_get_height()
- Returns the current height of the window.
-
-
-
-
-Again, you probably never want to use any of the window positioning functions as
-Game Maker takes care of these automatically.
-
-
-In rare cases you might want to know the position of the mouse with
-respect to the window. (Normally you always use the mouse position
-with respect to the room or with respect to a view.) The following
-functions exist for this.
-
-
-
- window_mouse_get_x()
- Returns the x-coordinate of the mouse in the window.
- window_mouse_get_y()
- Returns the y-coordinate of the mouse in the window.
- window_mouse_set(x,y)
- Sets the position of the mouse in the window to the indicated values.

Views
-
-As you should know you can define up to eight different views when designing rooms.
-A view is defined by its view area in the room and its viewport on the screen
-(or to be precise in the drawing region within the window). Using views you can
-show different parts of the room at different places on the screen.
-Also, you can make sure that a particular object always stays visible.
-
-
-You can control the views from within code. You can make views
-visible and invisible and change the place or size of the views
-in the drawing region or the position and size of the view in
-the room (which is in particular useful when you indicate no object
-to be visible). You can change the size of the horizontal and vertical
-border around the visible object, and you can indicate which object
-must remain visible in the views. The latter is very important when
-the important object changes during the game. For example, you might
-change the main character object based on its current status.
-Unfortunately, this does mean that it is no longer the object
-that must remain visible. This can be remedied by one line of
-code in the creation event of all the possible main objects
-(assuming this must happen in the first view):
-
-
-
-
-{
- view_object[0] = object_index;
-}
-
-
-
-
-
-The following variables exist that influence the view. All, except the first two are
-arrays ranging from 0 (the first view) to 7 (the last view).
-
-
-
- view_enabled
- Whether views are enabled or not.
- view_current*
- The currently drawn view (0-7). Use this only in the
- drawing event. You can for example check this variable to draw certain things in only one
- view. Variable cannot be changed.
- view_visible[0..7]
- Whether the particular view is visible on the screen.
- view_xview[0..7]
- X position of the view in the room.
- view_yview[0..7]
- Y position of the view in the room.
- view_wview[0..7]
- Width of the view in the room.
- view_hview[0..7]
- Height of the view in the room.
- view_xport[0..7]
- X-position of the viewport in the drawing region.
- view_yport[0..7]
- Y-position of the viewport in the drawing region.
- view_wport[0..7]
- Width of the viewport in the drawing region.
- view_hport[0..7]
- Height of the viewport in the drawing region.
- view_angle[0..7]
- Rotation angle used for the view in the room (counter-clockwise in degrees).
- view_hborder[0..7]
- Size of horizontal border around the visible object (in pixels).
- view_vborder[0..7]
- Size of vertical border around visible object (in pixels).
- view_hspeed[0..7]
- Maximal horizontal speed of the view.
- view_vspeed[0..7]
- Maximal vertical speed of the view.
- view_object[0..7]
- Object whose instance must remain visible in the view.
- If there are multiple instances of this object only the first one is followed. You can
- also assign an instance id to this variable. In that case the particular instance is
- followed.
-
-
-
-
-Note that the size of the image on the screen is decided based on the visible views at the
-beginning of the room. If you change views during the game, they might no longer fit on
-the screen. The screen size though is not adapted automatically. So if you need this you
-have to do it yourself, using the following functions:
-
-
-
- window_set_region_size(w,h,adaptwindow)
- Set the width and height of the drawing region in the window.
- adaptwindow indicates whether the window size must be adapted
- if the region does not fit in. The window size will always be
- adapted if you use fixed scaling. (See the function
- window_set_region_scale().)
- window_get_region_width()
- Returns the current width of the drawing region.
- window_get_region_height()
- Returns the current height of the drawing region.
-
-
-
-
-In a game you often need the position of the mouse cursor. Normally you use
-for this the variables mouse_x and mouse_y. When there are multiple views,
-these variables give the mouse position with respect to the view the mouse
-is in. Sometimes though, you might need the mouse position with respect to
-a particular view, also when it is outside that view. For this the
-following functions exist.
-
-
-
- window_view_mouse_get_x(id)
- Returns the x-coordinate of the mouse with respect to the view with index id.
- window_view_mouse_get_y(id)
- Returns the y-coordinate of the mouse with respect to the view with index id.
- window_view_mouse_set(id,x,y)
- Sets the position of the mouse with respect to the view with index id.
- window_views_mouse_get_x()
- Returns the x-coordinate of the mouse with respect to the view it is in
- (same as mouse_x).
- window_views_mouse_get_y()
- Returns the y-coordinate of the mouse with respect to the view it is in
- (same as mouse_y).
- window_views_mouse_set(x,y)
- Sets the position of the mouse with respect to the first view that is visible.

Repainting the screen
-
-Normally at the end of each step the room is repainted on the screen. But in rare
-circumstances you need to repaint the room at other moments. This happens when your
-program takes over the control. For example, before sleeping a long time a repaint might
-be wanted. Also, when your code displays a message and wants to wait for the player to
-press a key, you need a repaint in between. There are two different routines to do this.
-
-
-
- screen_redraw()
- Redraws the room by calling all draw events.
- screen_refresh()
- Refreshes the screen using the current room image (not
- performing drawing events).
-
-
-
-To understand the second function, you will need to understand more fully how drawing
-works internally. There is internally an image on which all drawing happens. This image is
-not visible on the screen. Only at the end of a step, after all drawing has taken place,
-is the screen image replaced by this internal image. (This is called double buffering.)
-The first function redraws the internal image and then refreshes the screen image. The
-second function only refreshes the image on the screen.
-
-
-Now you should also realize why you cannot use drawing actions or functions in other
-events than drawing events. They will draw things on the internal image but these won't be
-visible on the screen. And when the drawing events are performed, first the room
-background is drawn, erasing all you drew on the internal image. But when you use
-screen_refresh() after your drawing, the updated image will become visible on the
-screen. So, for example, a script can draw some text on the screen, call the refresh
-function and then wait for the player to press a key, like in the following piece of code.
-
-
-
-
-{
- draw_text(room_width/2,100,'Press any key to continue.');
- screen_refresh();
- keyboard_wait();
-}
-
-
-
-
-
-Please realize that, when you draw in another event than the drawing event, you draw
-simply on the image, not in a view! So the coordinates you use are the same as if there
-are no views.
-Be careful when using this technique. Make sure you understand it first and realize that
-refreshing the screen takes some time.
-
-
-When you are drawing the room yourself it can be useful to NOT let it be drawn automatic
-at all. For example, you might want to draw the room only every 5 steps. You can use the
-following functions for this:
-
-
-
- set_automatic_draw(value)
- Indicates whether to automatically redraw the room (true, default) or not (false).
-
-
-
-Finally there is a function with which you can set whether to synchronize the drawing with
-the refresh frequency of the monitor:
-
-
-
- set_synchronization(value)
- Indicates whether to synchronize the drawing with the refresh frequency of the monitor.
-
-
-
-You can also force a wait for the next vertical synchronization using the following function:
-
-
-
- screen_wait_vsync()
- Waits for the next vertical synchronization of the monitor.

Sound and music
-
-Sound plays a crucial role in computer games.
-Sounds are added to your game in the form of sound resources. Make sure that
-the names you use are valid variable names. As you will have seen you can
-indicate four different types of sound: normal sounds, background music,
-3D sounds, and sounds that must be played through the media player.
-
-
-Normal sounds are used for sound effects. In general wave files are
-used for this. Many of them can play at the same
-moment (even multiple instances of the same normal sound). You can apply
-all sorts of effects to them.
-
-
-Background music typically consist of midi files but sometimes also wave
-files are used. Sound effects can be applied to it. The only difference
-with normal sounds is that only one background music can play at any moment.
-If you start one the current one is stopped.
-
-
-3D sounds allow for 3D sound effects which is described below. They are mono
-sounds (wave or midi).
-
-
-Finally, if you want to use another sound type, in particular mp3, these cannot
-be played through DirectX. As a result the normal media player must be used for
-this. This is much more limited. Only one sound can play at the same time. No
-effects can be applied (not even volume changes) and the timing for e.g.
-looping sounds is poor. There can also be delays in playing these sounds. You
-are strongly encouraged not to use them. (Some computers might also not support them)
-
-
-
-
-Information on sound and music can be found in the following pages:

Basic sound functions
-
-
-There are five basic functions related to sounds, two to play a sound,
-one to check whether a sound is playing, and two to stop sounds. Most take
-the index of the sound as argument. The name of the sound represents its
-index. But you can also store the index in a variable, and use that.
-
-
-
- sound_play(index)
- Plays the indicates sound once. If the sound is background music the current
- background music is stopped.
- sound_loop(index)
- Plays the indicates sound, looping continuously. If the sound is background music the current
- background music is stopped.
- sound_stop(index)
- Stops the indicates sound. If there are multiple sounds with this index playing
- simultaneously, all will be stopped.
- sound_stop_all()
- Stops all sounds.
- sound_isplaying(index)
- Returns whether (a copy of) the indicated sound is playing. Note that this functions
- returns true when the sound actually plays through the speakers. After you call the
- function to play a sound it does not immediately reach the speakers so the function
- might still return false for a while. Similar, when the sound is stopped you still hear
- it for a while (e.g. because of echo) and the function will still return true.
-
-
-
-It is possible to use further sound effects. In particular you can
-change the volume and the pan, that is, whether the sound comes from the
-left or right speaker. In all these cases the volume can only be reduced.
-These functions do not work for files that play through the media player
-(like mp3 files).
-
-
-
- sound_volume(index,value)
- Changes the volume for the indicated sound (0 = low, 1 = high).
- sound_global_volume(value)
- Changes the global volume for all sounds (0 = low, 1 = high).
- sound_fade(index,value,time)
- Changes the volume for the indicated sound to the new value(0 = low, 1 = high)
- during the indicated time (in milliseconds). This can be used to fade out or
- fade in music.
- sound_pan(index,value)
- Changes the pan for the indicated sound (-1 = left, 0 = center, 1 = right).
- sound_background_tempo(factor)
- Changes the tempo of the background music (if it is a midi file). factor
- indicates the factor with which to multiply the tempo. So a value of 1 corresponds
- to the normal tempo. Larger values correspond to a faster tempo, smaller values
- to a slower tempo. Must lie between 0.01 and 100.
-
-
-
-Besides midi and wave files (and mp3 file) there is actually a fourth type of file
-that can be played: direct music files. These have the extension .sgt. Such files
-though often refer to other files describing e.g. band or style information. To
-find these files, the sound system must know where they are located. To this end
-you can use the following functions to set the search directory for files. Note though
-that you must add the files yourself. Game Maker does not automatically include
-such additional files.
-
-
-
- sound_set_search_directory(dir)
- Sets the directory in which direct music files are to be found. The dir string
- should not incluce the final backslash.

Sound effects
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Sound effects can be used to change the way sounds and background music sounds. Realize that
-sound effects only apply to wave files and midi files, not to mp3 files. This section describes
-the functions that exist for using and changing sound effects. Realize that to use these
-functions you need to have a good understanding of how sound and synthesizers work. No explanation
-of the different parameters is given here. Search the web or books for further informations.
-
-
-
-To apply a sound effect to a particular sound you can either indicate this when defining the
-sound resource or you can use the following function
-
-
-
- sound_effect_set(snd,effect)
- Sets a (combination of) sound effect(s) for the indicated sound. effect can
- be any of the following values:
-
- You can set a combination of effects by adding up the values. So e.g. you can use
-
-
-sound_effect_set(snd,se_echo+se_reverb);
-
-
- to get a combination of echo and reverb effects.
-
-
-
-All effects have some default settings. You can change these settings once an effect has been applied
-to a sound. The order here is crucial. You first apply the effect to the sound and next set the
-parameters for it. Once you reapply effects to the sound, the settings are gone and you have to
-set them again. Note that all parameters must lie in a particular range, which is indicated
-below. The following functions exist for changing effect parameters:
-
-
-
- sound_effect_chorus(snd,wetdry,depth,feedback,frequency,wave,delay,phase)
- Sets the parameters for the chorus effect for the indicated sound. The following
- parameters can be set:
-
- wetdry Ratio of wet (processed) signal to dry (unprocessed) signal.
- (range: 0 to 100, default 50)
- depth Percentage by which the delay time is modulated by the low-frequency oscillator,
- in hundredths of a percentage point. (range: 0 to 100, default 25)
- feedback Percentage of output signal to feed back into the effect's input.
- (range: -99 to 99, default 0)
- frequency Frequency of the LFO. (range: 0 to 10, default 0)
- wave Waveform of the LFO. (0 = triangle, 1 = wave, default 1)
- delay Number of milliseconds the input is delayed before it is played back.
- (range: 0 to 20, default 0)
- phase Phase differential between left and right LFOs.
- (range: 0 to 4, default 2)
-
- sound_effect_echo(snd,wetdry,feedback,leftdelay,rightdelay,pandelay)
- Sets the parameters for the echo effect for the indicated sound. The following
- parameters can be set:
-
- wetdry Ratio of wet (processed) signal to dry (unprocessed) signal.
- (range: 0 to 100, default 50)
- feedback Percentage fed back into input (range: 0 to 100, default 0)
- leftdelay Delay for left channel, in milliseconds. (range: 1 to 2000, default 333)
- rightdelay Delay for right channel, in milliseconds. (range: 1 to 2000, default 333)
- pandelay Whether to swap left and right delays with each successive echo.
- (0 = don't swap, 1 = swap, default 0)
-
- sound_effect_flanger(snd,wetdry,depth,feedback,frequency,wave,delay,phase)
- Sets the parameters for the flanger effect for the indicated sound. The following
- parameters can be set:
-
- wetdry Ratio of wet (processed) signal to dry (unprocessed) signal.
- (range: 0 to 100, default 50)
- depth Percentage by which the delay time is modulated by the low-frequency oscillator,
- in hundredths of a percentage point. (range: 0 to 100, default 25)
- feedback Percentage of output signal to feed back into the effect's input.
- (range: -99 to 99, default 0)
- frequency Frequency of the LFO. (range: 0 to 10, default 0)
- wave Waveform of the LFO. (0 = triangle, 1 = wave, default 1)
- delay Number of milliseconds the input is delayed before it is played back.
- (range: 0 to 20, default 0)
- phase Phase differential between left and right LFOs.
- (range: 0 to 4, default 2)
-
- sound_effect_gargle(snd,rate,wave)
- Sets the parameters for the gargle effect for the indicated sound. The following
- parameters can be set:
-
- rate Rate of modulation, in Hertz.
- (range: 1 to 1000, default 1)
- wave Shape of the modulation wave. (0 = triangle, 1 = square, default 0)
-
- sound_effect_reverb(snd,gain,mix,time,ratio)
- Sets the parameters for the reverb effect for the indicated sound. The following
- parameters can be set:
-
- gain Input gain of signal, in decibels (dB). (range: -96 to 0, default 0)

3D sound
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-3D sounds refers to sound that has a position (and velocity) with respect to the listener.
-Although its most prominent use is in 3D games you can also effectively use it in 2D games.
-The idea is that a sound has a position in space.
-In all functions the listener is assumed to be at position (0,0,0). The system
-calculates how the listener would hear the sound and adapt it accordingly. The effect is
-especially good when you have a good speaker system but is already works on small speakers.
-
-
-Besides a position, the sound can also has a velocity. This leads to well-known
-doppler effects which are correctly modelled. Finally the sound can have an
-orientation and, again, the sound is adapted accordingly.
-
-
-Game Maker supports 3D sound options through the functions below.
-They only work for sound resources that were indicated to be 3D. (The disadvantage is that
-3D sounds will be mono, not stereo.)
-
-
-
- sound_3d_set_sound_position(snd,x,y,z)
- Sets the position of the indicated sound with respect to
- the listener to the indicated position in space.
- Values on the x-axis increase from left to right, on the y-axis from down to up,
- and on the z-axis from near to far. The values are measured in meters. The volume
- with which the sound is heard depends on this measure in the same way as in
- the real world.
- sound_3d_set_sound_velocity(snd,x,y,z)
- Sets the velocity of the indicated sound to the indicated vector in space.
- Please note that setting the velocity does not mean that the position changes.
- The velocity is only used for calculating doppler effects. So if you want to move
- the sound you must yourself change the position of the sound.
- sound_3d_set_sound_distance(snd,mindist,maxdist)
- Sets the minimum distance at which the sound does no longer increase in
- loudness and the maximum distance at which the sound can no longer be heard.
- So when the distance lies between 0 and the minimum distance the sound
- is at maximal amplitude. When between the minimal distance and the maximal
- distance the amplitude slowly decreases until either the maximal distance
- is reached or the sound is anyway no longer audible. Default the minimum
- distance is 1 meter and the maximal distance is 1 billion meters.
- sound_3d_set_sound_cone(snd,x,y,z,anglein,angleout,voloutside)
- Normally sound has the same amplitude at a given distance in all directions.
- You can set the sound cone to change this and make sound directional. x,y,z specify
- the direction of the sound cone. anglein specifies the inside angle. If
- the listener is inside this angle it hears the sound at its normal volume. angleout
- specifies the outside angle. When the listener is outside this the volume is indicated
- with voloutside. To be precise, voloutside is a negative number
- that indicates the number of hundreds of decibel that must be subtracted from the
- inside volume. Between the inside and outside angle the volume gradually decreases.

-
- MCI_command(str)
- This functions sends the command string to the Windows multimedia system
- using the Media Control Interface (MCI). It returns the return string.
- You can use this to control all sorts of multimedia devices. See the Windows

Splash screens
-
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Many games have so-called splash screens. These screens show a video, an image,
-or some text. Often they are used at the beginning of the game (as an intro),
-the beginning of a level, or at the end of the game (for example the credits).
-In Game Maker such splash screens with text, images or video can be
-shown at any moment during the game.
-
-
-Default these splash screens are shown inside the game window, but it
-is also possible to show them in a separate window. The game is interrupted
-while the splash screen is shown. The player can return to the game by
-pressing the escape key or by clicking with the mouse in the window.
-(These settings can be changed; see below.)
-
-
-The following functions can be used to display the splash screens:
-
-
-
- splash_show_video(fname,loop)
- Shows a video splash screen. fname is the name of the video file.
- Whether a particular movie file is supported depends on the drivers
- on the machine. Typically you can use .avi, .mpg, and .wmv files but
- avoid special codecs. You best put this file in the folder of the game
- yourself or in a subfolder. loop indicates whether to loop the video.
- splash_show_text(fname,delay)
- Shows a text splash screen. fname is the name of the text file. You can
- either display standard text files (.txt) or rich text files (.rtf). Only
- part of the rich text features are taken into account. E.g. images and
- other embedded objects are not shown.
- delay indicates the delay in milliseconds before returning
- to the game. use 0 or a negative value to wait until the player presses the escape key
- or clicks with the mouse in the window. (Note that no scrollbar will be shown nor is
- there another way to scroll the text. So the text must fit the window.)
- splash_show_image(fname,delay)
- Shows an image splash screen. fname is the name of the image
- file. Many image types are supported (for example .bmp, .jpg, .tif, and .wmf) but
- no animated images. delay is the delay in milli seconds before returning
- to the game.
- splash_show_web(url,delay)
- Shows a web page splash screen. url is the url of the webpage (starting
- with http://) or it is the file name for a local html file. Note
- however that you must provide the full path for this to work. So you best
- e.g. use as url something like working_directory + "\index.html".
- delay is the delay in milli seconds before returning
- to the game.
-
-
-
-You can change the way the splash screens are displayed using the functions below:
-
-
-
- splash_set_main(main)
- Indicated whether the splash screen must be shown in the main
- game window (true, default) or in a separate window (false).
- splash_set_scale(scale)
- Sets the scale factor to be used when displaying a splash video
- or image. When using a value of 0 the scale factor is chosen
- such that the window is filled (default).
- splash_set_cursor(vis)
- Sets whether the cursor should be visible in the splash screen.
- Default it is visible. For movies the cursor cannot be switched off.
- splash_set_color(col)
- Sets the color of the area surrounding the image or video.
- splash_set_caption(cap)
- Sets the caption for the splash window. This only has effect when
- is a separate splash window is used. Default the empty string is used.
- splash_set_fullscreen(full)
- Indicates whether to use a full screen window or not. This only has effect when
- is a separate splash window is used. Default a normal window is used.
- splash_set_border(border)
- Indicates whether the window should have a border. This only has effect when
- is a separate normal splash window is used. Default a border is used.
- splash_set_size(w,h)
- Sets the size of the splash window. This only has effect when
- is a separate normal splash window is used. Default size is 640x480.
- splash_set_position(x,y)
- Sets the position of the splash window. This only has effect when
- is a separate normal splash window is used. Default Windows determines the position.
- splash_set_adapt(adapt)
- Indicated whether the size of the window must be adapted to the scaled
- size of the video or image. This only has effect when
- is a separate splash window is used. Default adapt is true.
- splash_set_top(top)
- Indicates whether the window should stay on top of other windows. This only has effect when
- is a separate splash window is used. Default the value is true.
- splash_set_interrupt(interrupt)
- Indicates whether the game play should be interrupted while showing the
- splash window. This only has effect when
- is a separate splash window is used. Default the value is true.
- splash_set_stop_key(stop)
- Indicates whether to stop the display of the splash screen when the player pressed
- the Escape key. Default the value is true.
- splash_set_stop_mouse(stop)
- Indicates whether to stop the display of the splash screen when the player pressed
- the mouse inside the splash screen. Default the value is true.
- splash_set_close_button(show)
- Indicates whether to show a close button in the top right corner of the splash screen.
- This is useful when running games in full screen mode or without a border.
- Default the value is true.
-
-
-
-There is one particular type of splash info, which is the game information that the
-user can enter in Game Maker. You can display it using the following function.
-You can also load a separate info file. This is closely related to the displaying of
-the text splash screen but the display is governed by the settings provided when defining
-the game information and not by the settings above. It is also displayed in a different
-window, so it is possible to display both the game information and a splash screen at the same
-moment. These functions also work in the Lite Edition.
-
-
-
- show_info()
- Displays the game information window.
- load_info(fname)
- Loads the game information from the file named fname. This should be a rich
- text file (.rtf). This makes it possible to show different help files at different moments.
- Note that contrary to the spash screens, this rtf file cannot contain images.

- sound_get_name(ind)
- Returns the name of the sound with the given index.
- sound_get_kind(ind)
- Returns the kind of the sound with the given index (0=normal, 1=background, 2=3d, 3=mmplayer).
- sound_get_preload(ind)
- Returns whether the sound with the given index has preload set.
-
-
-
-
-Sounds use many resources and most systems can store and play only a limited number of sounds. If you
-make a large game you would like to have more control over which sounds are loaded in audio memory at what
-times. You can use the switch off the preload option for sounds to make sure sounds are only loaded when used.
-This though has the problem that you might get a small hiccup when the sound is used first. Also,
-sounds are not automatically unloaded when you don't need them anymore.
-For more control you can use the following functions.
-
-
-
- sound_discard(index)
- Frees the audio memory used for the indicated sound.
- sound_restore(index)
- Restores the indicated sound in audio memory for immediate playing.

Changing resources
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-It is possible to create new resources during the game. Also you can change existing
-resources. This chapter describes the possibilities. Be warned though. Changing
-resources easily leads to serious errors in your games!!! You must follow the
-following rules when changing resources:
-
-
-
Don't change resources that are being used. This will lead to errors! For example,
- don't change a sprite that is being used by an instance.
-
When you save the game during playing, added and changed resources are NOT stored
- with the save game. So if you load the saved game later, these might not be there anymore.
- In general, when you manipulate resources you can no longer use the built-in system for
- loading and saving games.
-
When you restart the game during playing, the changed resources are NOT restored to
- their original shape. In general, when you manipulate resources you can no longer use the
- action or function to restart the game.
-
Resource manipulation can be slow. For example, changing sprites or backgrounds is
- relatively slow. So don't use it during the game play.
-
Creating resources during game play (in particular sprites and background) easily
- uses huge amount of memory. So be extremely careful with this. For example, if you have a
- 32 frame 128x128 animated sprite and you decide to create 36 rotated copies of it you will
- use up 36x32x128x128x4 = 72 MB of memory!
-
Make sure you delete resources you no longer need. Otherwise the system soon runs
- out of memory.
-
-
-In general, you should not change any resources during game play. Better create and change
-the resources at the beginning of the game or maybe at the beginning of a room.
-
-
-
-
-Information on changing resources can be found in the following pages:

Sprites
-
-The following routines are available for changing sprite properties:
-
-
-
- sprite_set_offset(ind,xoff,yoff)
- Sets the offset of the sprite with the given index.
-
-
-
-
-The following routines can be used to create new sprites and to remove them.
-
-
-
- sprite_duplicate(ind)
- Creates a duplicate of the sprite with the given
- index. It returns the index of the new sprite. When an error occurs -1 is returned.
- sprite_assign(ind,spr)
- Assigns the indicated sprite to sprite ind. So
- this makes a copy of the sprite. In this way you can easily set an existing sprite to a
- different, e.g. new sprite.
- sprite_merge(ind1,ind2)
- Merges the images from sprite ind2 into sprite
- ind1, adding them at the end. If the sizes don't match the sprites are stretched to fit.
- Sprite ind2 is not deleted!
- sprite_add(fname,imgnumb,removeback,smooth,xorig,yorig)
- Adds the image stored in the file fname to the set of sprite resources. Many different
- image file types can be dealt with. When the image is not a gif image it can be a strip
- containing a number of subimages for the sprite next to each other. Use imgnumb to
- indicate their number (1 for a single image). For (animated) gif images, this argument is
- not used; the number of images in the gif file is used. removeback indicates whether
- to make all pixels with the background color (left-bottom pixel) transparent.
- smooth indicates whether to smooth the edges.
- xorig and yorig
- indicate the position of the origin in the sprite. The function returns the index of the
- new sprite that you can then use to draw it or to assign it to the variable sprite_index
- of an instance. When an error occurs -1 is returned.
- sprite_replace(ind,fname,imgnumb,removeback,smooth,xorig,yorig)
- Same as above but in this case the sprite with index ind is replaced. The function returns whether
- it is successful.
- sprite_add_sprite(fname)
- Adds the sprite stored the file fname to the set of sprite resources. The file must be
- a .gmspr file that is saved in the sprite property form in Game Maker. As this
- file contains all sprite settings, no further arguments are required.
- The function returns the index of the
- new sprite that you can then use to draw it or to assign it to the variable sprite_index
- of an instance. When an error occurs -1 is returned.
- sprite_replace_sprite(ind,fname)
- Same as above but in this case the sprite with index ind is replaced. The function returns whether
- it is successful.
- sprite_create_from_screen(x,y,w,h,removeback,smooth,xorig,yorig)
- Creates a sprite by copying the given area from the screen.
- removeback indicates whether
- to make all pixels with the background color (left-bottom pixel) transparent.
- smooth indicates whether to smooth the boundaries. This makes it possible to create any
- sprite you want. Draw the image on the screen using the drawing functions and next create a sprite
- from it. (If you don't do this in the drawing event you can even do it in such a way that it is
- not visible on the screen by not refreshing the screen.) The other parameters are as above.
- The function returns the index of the new sprite. A work of caution is required here. Even
- though we speak about the screen, it is actually the drawing region that matters. The fact
- that there is a window on the screen and that the image might be scaled in this window does
- not matter.
- sprite_add_from_screen(ind,x,y,w,h,removeback,smooth)
- Adds an area of the screen as a next subimage to the sprite with index ind.
- sprite_create_from_surface(id,x,y,w,h,removeback,smooth,xorig,yorig)
- Creates a sprite by copying the given area from the surface with the given id.
- removeback indicates whether
- to make all pixels with the background color (left-bottom pixel) transparent.
- smooth indicates whether to smooth the boundaries.
- This makes it possible to create any sprite you want. Draw the image on the surface
- using the drawing functions and next create a sprite
- from it. The function returns the index of the new sprite. Note that alpha values are
- maintained in the sprite.
- sprite_add_from_surface(ind,id,x,y,w,h,removeback,smooth)
- Adds an area of the surface id as a next subimage to the sprite with index ind.
- sprite_delete(ind)
- Deletes the sprite from memory, freeing the memory used.
-
-
-
-
-The following routine exists to change the appearance of a sprite.
-
-
-
- sprite_set_alpha_from_sprite(ind,spr)
- Changes the alpha (transparancy) values in the sprite with index
- ind using the intensity values in the sprite spr. This cannot
- be undone.
-
-
-
-Finally, you can change the collision checking mask for the sprite with the following
-routine. Please realize that this does not work correctly when an instance with that sprite is
-already present in the room.
-
-
-
- sprite_collision_mask(ind,sepmasks,bboxmode,bbleft,bbright,bbtop,bbbottom,kind,tolerance)
- Changes the collision mask for the sprite with index
- ind. sepmasks indicates whether there must be separate collision masks
- for all subimages.
- bboxmode is the bounding box mode (0=automatic, 1=full image,
- 2=user defined). bbleft, bbright, bbtop, bbbottom indicate the bounding
- box in case of user defined bounding box. You can use 0 for all these values in the other cases.
- kind is the kind of mask (0=precise, 1=bounding box,
- 2=disk, 3=diamond). tolerance indicates the tolerance in the transparency value (0=no tolerance,
- 255=full tolerance).

- used as the character width. Finally, sep indicates
- the amount of white space that must separate the characters horizontally.
- A typical value would lie between 2 and 8 depending on the font size.
- font_replace(ind,name,size,bold,italic,first,last)
- Replaces the font ind with a new font, indicating the name,
- size, whether it is bold or italic, and the first and last
- character that must be created.

- path_set_precision(ind,prec)
- Sets the precision with which the smooth
- path is calculated (should lie between 1 and 8).
- path_add()
- Adds a new empty paths. The index of the path is returned.
- path_delete(ind)

- makes a copy of the path. In this way you can easily set an existing path to a different,
- e.g. new path.
- path_append(ind,path)
- Appends the indicated path to path ind.
- path_add_point(ind,x,y,speed)
- Adds a point to the path with the given
- index, at position (x,y) and with the given speed factor. Remember that a factor of 100
- corresponds to the actual speed. Lower values mean slowing down and higher mean speeding up.
- path_insert_point(ind,n,x,y,speed)
- Inserts a point in the path with
- the given index before point n, at position (x,y) and with the given speed factor.
- path_change_point(ind,n,x,y,speed)

- path_clear_points(ind)
- Clears all the points in the path, turning it into an empty path.
- path_reverse(ind)
- Reverses the path.
- path_mirror(ind)
- Mirrors the path horizontally (with respect to its center).
- path_flip(ind)
- Flips the path vertically (with respect to its center).
- path_rotate(ind,angle)
- Rotates the path counter clockwise over angle degrees (around its center).
- path_scale(ind,xscale,yscale)

Scripts
-
-Scripts cannot be changed during the execution of the game. The scripts are part of the
-game logic. Changing scripts would lead to self-rewriting code which very easily leads to
-errors. Also there are other ways to achieve this. If you really need to execute a piece
-of code that is not known at design time (e.g. from a file) you can use the following
-functions:
-
-
-
- execute_string(str,arg0,arg1,...)
- Execute the piece of code in the string str with the indicated arguments.
- execute_file(fname,arg0,arg1,...)
- Execute the piece of code in the file with the indicated arguments.
-
-
-
-
-Sometimes you want to store a script index in a variable and execute it. For this you can
-use the following function
-
-
-
- script_execute(scr,arg0,arg1,...)
- Execute the script with index scr with the given arguments.

Objects
-
-Also objects can be manipulated and created during the game play. NEVER change or delete
-an object for which there are instances. This can lead to unexpected effects as certain
-object properties are stored with the instance and, hence, changing them in the object
-will not have the desired effect.
-
-
-
- object_set_sprite(ind,spr)
- Sets the sprite of the object with the given
- index. Use -1 to remove the current sprite from the object.
- object_set_solid(ind,solid)
- Sets whether instances created of the object
- must default be solid (true or false).
- object_set_visible(ind,vis)
- Sets whether instances created of the object
- must default be visible (true or false).
- object_set_depth(ind,depth)
- Sets the default depth of instances created of the object.
- object_set_persistent(ind,pers)
- Sets whether instances created of the
- object must default be persistent (true or false).
- object_set_mask(ind,spr)
- Sets the sprite mask of the object with the
- given index. Use -1 to set the mask to be the sprite of the object.
- object_set_parent(ind,obj)
- Sets the parent of the object. Use -1 to not
- have a parent. Changing the parent changes the behavior of instances of the object.
-
-
-
-
-The following routines are useful for creating objects on the fly. As with all resource
-changing routines, be very careful that you don't create new objects all the time.
-
-
-
- object_add()
- Adds a new object. It returns the index of the object. You
- can now use this index in the routines above to set certain properties of the object and
- then you can use the index to create instances of the object.
- object_delete(ind)
- Deletes the object with the given index. Make sure no
- instances of the object exist in any of the rooms.
- object_event_add(ind,evtype,evnumb,codestr)
- To give the object a
- behavior we must define events for the object. You can only add code actions to events.
- You need to specify the object, the event type, the event number (use the constants that
- have been specified before for the event_perform() function). Finally you provide the code
- string that must be executed. You can add multiple code actions to each event.
- object_event_clear(ind,evtype,evnumb)
- You can use this function to clear
- all the actions for a particular event.
-
-
-
-
-Creating objects is in particular useful when you are designing scripts or action
-libraries. For example, an initialization script can create an object to display a text
-and another script can add such an object with a particular text. In this way you have a
-simple mechanism to display texts without the need to create objects using the standard
-interface.

Rooms
-
-Manipulating rooms on the fly is a dangerous thing to do. You have to realize that rooms
-change all the time due to what is happening in the game. This normally only involves the
-currently active room and there are many routines described in previous sections to
-manipulate the instances, backgrounds, and tiles in the active room. But changes in the
-active room will last if the room is persistent. Hence, you should never manipulate
-aspects of the currently active room or any room that is persistent and that has already
-been visited before. Such changes in general won't be noticed but might sometimes even
-lead to unexpected errors. Due to the fact that rooms are linked in a complicated way
-there is also no routine to delete a room.
-
-
-The following routines are available
-
-
-
- room_set_width(ind,w)
- Sets the width for the room with the indicated index.
- room_set_height(ind,h)
- Sets the height for the room with the indicated index.
- room_set_caption(ind,str)
- Sets the caption for the room with the indicated index.
- room_set_persistent(ind,val)
- Sets whether the room with the indicated
- index is persistent or not.
- room_set_code(ind,str)
- Sets the initialization code string for the room
- with the indicated index.
- room_set_background_color(ind,col,show)
- Sets the color properties for
- the room with the indicated index if is does not have a background image. col indicates
- the color and show indicates whether the color must be shown or not.
- room_set_background(ind,bind,vis,fore,back,x,y,htiled,vtiled,hspeed,vspeed,alpha)
- Sets background with index bind (0-7) for the room with the indicated index. vis
- indicates whether the background is visible and fore whether it is actually a foreground.
- back is the index of the background image. x,y indicate the position of the image and
- htiled and vtiled indicate whether the image must be tiled. hspeed and vspeed indicate the
- speed with which the background moves and alpha indicates an alpha translucency value (1 =
- solid and fastest).
- room_set_view(ind,vind,vis,xview,yview,wview,hview,xport,yport,wport,hport,hborder,vborder,hspeed,vspeed,obj)
- Sets the view with index vind (0-7) for the room with the indicated index. vis indicates
- whether the view is visible. xview, yview, wview, and hview indicate the position of the view
- in the room. xport, yport, wport, and hport indicate the position on the screen.
- When the view must follow an object
- hborder and vborder indicate the minimal visible border that must be kept around the
- object. hspeed and vspeed indicate the maximal speed with which the view can move. obj is
- the index of the object or the index of the instance.
- room_set_view_enabled(ind,val)
- Sets whether views must be enabled for
- the room with the indicated index.
- room_add()
- Adds a new room. It returns the index of the room. Note that
- the room will not be part of the room order. So the new room does not have a previous or a
- next room. If you want to move to an added room you must provide the index of the room.
- room_duplicate(ind)
- Adds a copy of the room with the given index. It returns the index of the room.
-room_assign(ind,room)
- Assigns the indicated room to room ind. So this makes a copy of the room.
- room_instance_add(ind,x,y,obj)
- Adds a new instance of object obj to the
- room, placing it at the indicate position. It returns the index of the instance.
- room_instance_clear(ind)
- Removes all instances from the indicated room.
- room_tile_add(ind,back,left,top,width,height,x,y,depth)
- Adds a new tile
- to the room at the indicate position. It returns the index of the tile. back is the
- background from which the tile is taken. left, top, width and height indicate the part of
- the background that forms the tile. x,y is the position of the tile in the room and depth
- is the depth of the tile.
- room_tile_add_ext(ind,back,left,top,width,height,x,y,depth,xscale,yscale,alpha)
- Same as the previous routine but this time you can also specify a scaling factor
- in x and y direction and an alpha transparency for the tile.
- room_tile_clear(ind)
- Removes all tiles from the indicated room.

Files
-
-It is useful to use external files in games.
-For example, you could make a file that
-describes at what moments certain things should happen. Also you probably
-want to save information for the next time the game is run (for example,
-the current room). The following functions exist to read and write data
-in text files:
-
-
-
- file_text_open_read(fname)
- Opens the file with the indicated name for reading. The function
- returns the id of the file that must be used in the other functions.
- You can open multiple files at the same time (32 max). Don't forget
- to close them once you are finished with them.
- file_text_open_write(fname)
- Opens the indicated file for writing, creating it if it does not
- exist. The function returns the id of the file that must be
- used in the other functions.
- file_text_open_append(fname)
- Opens the indicated file for appending data at the end, creating
- it if it does not exist. The function returns the id of the file
- that must be used in the other functions.
- file_text_close(fileid)
- Closes the file with the given file id.
- file_text_write_string(fileid,str)
- Writes the string to the file with the given file id.
- file_text_write_real(fileid,x)
- Write the real value to the file with the given file id. (As separator between the integer and decimal
- part always a dot is used.
- file_text_writeln(fileid)
- Write a newline character to the file.
- file_text_read_string(fileid)
- Reads a string from the file with the given file id and returns this
- string. A string ends at the end of line.
- file_text_read_real(fileid)
- Reads a real value from the file and returns this value.
- file_text_readln(fileid)
- Skips the rest of the line in the file and starts at the start of the next line.
- file_text_eof(fileid)
- Returns whether we reached the end of the file.
- file_text_eoln(fileid)
- Returns whether we reached the end of a line in the file.
-
-
-
-To manipulate files in the file system you can use the following functions:
-
-
-
- file_exists(fname)
- Returns whether the file with the given name exists (true) or not (false).
- file_delete(fname)
- Deletes the file with the given name.
- file_rename(oldname,newname)
- Renames the file with name oldname into newname.
- file_copy(fname,newname)
- Copies the file fname to the newname.
- directory_exists(dname)
- Returns whether the indicated directory does exist.
- The name must include the full path, not a relative path.
- directory_create(dname)
- Creates a directory with the given name (including the path towards it) if it does not exist.
- The name must include the full path, not a relative path.
- file_find_first(mask,attr)
- Returns the name of the first file that satisfies the mask and the
- attributes. If no such file exists, the empty string is returned.
- The mask can contain a path and can contain wildchars, for example
- 'C:\temp\*.doc'. The attributes give the additional files you want
- to see. (So the normal files are always returned when they satisfy
- the mask.) You can add up the following constants to see the
- type of files you want:
-
-
- file_find_next()
- Returns the name of the next file that satisfies the previously given mask
- and the attributes. If no such file exists, the empty string is returned.
- file_find_close()
- Must be called after handling all files to free memory.
- file_attributes(fname,attr)
- Returns whether the file has all the attributes given in attr.
- Use a combination of the constants indicated above.
-
-
-
-The following functions can be used to change file names. Note that these
-functions do not work on the actual files they only deal with the strings.
-
-
-
- filename_name(fname)
- Returns the name part of the indicated file name, with the extension but without the path.
- filename_path(fname)
- Returns the path part of the indicated file name, including the final backslash.
- filename_dir(fname)
- Returns the directory part of the indicated file name, which normally
- is the same as the path except for the final backslash.
- filename_drive(fname)
- Returns the drive information of the filename.
- filename_ext(fname)
- Returns the extension part of the indicated file name, including the leading dot.
- filename_change_ext(fname,newext)
- Returns the indicated file name, with the extension (including the dot)
- changed to the new extension. By using an empty string as the new
- extension you can remove the extension.
-
-
-
-In rare situations you might need to read data from binary files. The following
-low-level routines exist for this:
-
-
-
- file_bin_open(fname,mod)
- Opens the file with the indicated name. The mode indicates what
- can be done with the file: 0 = reading, 1 = writing, 2 = both reading
- and writing). When the file does not exist it is created.
- The function returns the id of the file that must be
- used in the other functions. You can open multiple files at the same
- time (32 max). Don't forget to close them once you are finished with them.
- file_bin_rewrite(fileid)
- Rewrites the file with the given file id, that is, clears it and
- starts writing at the start.
- file_bin_close(fileid)
- Closes the file with the given file id.
- file_bin_size(fileid)
- Returns the size (in bytes) of the file with the given file id.
- file_bin_position(fileid)
- Returns the current position (in bytes; 0 is the first position)
- of the file with the given file id.
- file_bin_seek(fileid,pos)
- Moves the current position of the file to the indicated position.
- To append to a file move the position to the size of the file before writing.
- file_bin_write_byte(fileid,byte)
- Writes a byte of data to the file with the given file id.
- file_bin_read_byte(fileid)
- Reads a byte of data from the file and returns this.
-
-
-
-If the player has checked secure mode in his preferences, for a number of
-these routines, you are not allowed to specify a path, and only files in
-the application folder can e.g. be written.
-
-
-If you included files in the game executable and did not automatically export them at the
-start of the game, you can use the following functions to do this.
-
-
-
- export_include_file(fname)
- Exports the included file with the name fname. This must be a string variable,
- so don't forget the quotes.
- export_include_file_location(fname,location)
- Exports the included file with the name fname to the given location. Location must contain
- the path and the filename.
- discard_include_file(fname)
- Discard the included file with the name fname, freeing the memory used. This must be a string variable,
- so don't forget the quotes.
-
-
-
-The following four read-only variables can be useful:
-
-
-
- game_id*
- Unique identifier for the game. You can use this if you need a unique file name.
- working_directory*
- Working directory for the game. (Not including the final backslash.)
- program_directory*
- Directory in which the game executable is stored. (Not including the final backslash.)
- When you run a standalone game this is normally the same as the working directory unless
- the game e.g. opens a file using the file selector. Note that when testing a
- game you are creating the program and working directory will be different. In that
- case the working directory is the place where the editable version is stored while
- the program directory is a temporary directory for testing.
- temp_directory*
- Temporary directory created for the game. (Not including the final backslash.)
- You can store temporary files here. They will be removed at the end of the game.
-
-
-
-In certain situations you might want to give players the possibility of providing
-command line arguments to the game they are running (for example to create
-cheats or special modes). To get these arguments you can use the following
-two routines.
-
-
-
- parameter_count()
- Returns the number of command-line parameters. The actual parameters can be retrieved with
- the following function.
- parameter_string(n)
- Returns command-line parameters n. The first parameter has index 1. The last one has
- index parameter_count(). Index 0 is a special one. It is the filename of the
- game executable (including the path).
-
-
-
-You can read the value of environment variables using the following function:
-
-
-
- environment_get_variable(name)
- Returns the value (a string) of the environment variable with the given name.
-
-
-
-Finally, if you are interested in the size of the disk and the free space, you
-can use the following functions:
-
-
-
-
- disk_size(drive)
- Returns the size of the indicated drive in bytes. drive must be a
- capital letter, e.g. 'C'. If you do not provide the drive, the
- drive of the current working directory is used.
- disk_free(drive)
- Returns the amount of free space on the indicated drive in bytes. drive must be a
- capital letter, e.g. 'C'. If you do not provide the drive, the
- drive of the current working directory is used.

Registry
-
-If you want to store a small amount of information between runs of the
-game there is a simpler mechanism than using a file. You can use the
-registry. The registry is a large database that Windows maintains to
-keep track of all sorts of settings for programs. An entry has a name,
-and a value. You can use both string and real values. The following
-functions exist:
-
-
-
- registry_write_string(name,str)
- Creates an entry in the registry with the given name and string value.
- registry_write_real(name,x)
- Creates an entry in the registry with the given name and real value.
- registry_read_string(name)
- Returns the string that the given name holds. (The name must exist.
- Otherwise an empty string is returned.)
- registry_read_real(name)
- Returns the real value that the given name holds. (The name must exist.
- Otherwise the number 0 is returned.)
- registry_exists(name)
- Returns whether the given name exists.
-
-
-
-Actually, values in the registry are grouped into keys. The above routines
-all work on values within the key that is especially created for your game.
-Your program can use this to obtain certain information about the system
-the game is running on. You can also read values in other keys. You can
-write them also but be very careful. YOU CAN EASILY DESTROY YOUR SYSTEM this
-way. (Write is not allowed in secure mode.) Note that keys are again
-placed in groups. The following routines default work on the group
-HKEY_CURRENT_USER. But you can change the root group. So, for
-example, if you want to find out the current temp dir, use
-
-
- registry_write_string_ext(key,name,str)
- Creates an entry in the key in the registry with the given name and string value.
- registry_write_real_ext(key,name,x)
- Creates an entry in the key in the registry with the given name and real value.
- registry_read_string_ext(key,name)
- Returns the string that the given name in the indicated key holds.
- (The name must exist. Otherwise an empty string is returned.)
- registry_read_real_ext(key,name)
- Returns the real value that the given name in the indicated key holds.
- (The name must exist. Otherwise the number 0 is returned.)
- registry_exists_ext(key,name)
- Returns whether the given name exists in the given key.
- registry_set_root(root)
- Sets the root for the other routines. Use the following values:

INI files
-
-To pass certain parameter settings to programs a standard mechanism is the use of
-INI files. INI files contain sections and each section contains a number of
-name-value pairs. For example, here is a typical INI file:
-
-
-
-
-[Form]
-Top=100
-Left=100
-Caption=The best game ever
-[Game]
-MaxScore=12324
-
-
-
-
-This file contains two sections, one call Form and the other called Game.
-The first section contains three pairs. The first two have a real value
-while the third has a string value. Such INI files are easy to create and change.
-The following functions exist in Game Maker to
-read and change the data in them.
-
-
-
- ini_open(name)
- Opens the INI file with the given name. The ini file must be
- stored in the same folder as the game!
- ini_close()
- Closes the currently open INI file.
- ini_read_string(section,key,default)
- Reads the string value of the indicated key in the indicated
- section. When the key or section does not exist the default value is returned.
- ini_read_real(section,key,default)

Executing programs
-
-Game Maker also has the possibility to start external programs.
-There are two functions available for this: execute_program and execute_
-shell. The function execute_program starts a program, possibly with some
-arguments. It can wait for the program to finish (pausing the game) or
-continue the game. The function execute_shell opens a file. This can be
-any file for which some association is defined, e.g. an html-file, a word
-file, etc. Or it can be a program. It cannot wait for completion so the
-game will continue.
-
-
-
- execute_program(prog,arg,wait)
- Executes program prog with arguments arg. wait indicates whether to wait for finishing.
- execute_shell(prog,arg)
- Executes the program (or file) in the shell.
-
-
-
-Both functions will not work if the player sets the secure mode
-in the preferences. You can check this using the read-only variable:
-
-
-
- secure_mode*
- Whether the game is running in secure mode.

Data structures
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-In games you often need to store information. For example you need to store
-lists of items that a person carries or you want to store places that still
-need to be visited. You can use the arrays for this. But if you want to do more
-complicated operations, like sorting the data or searching for a particular item,
-you need to write large pieces of GML code which can be slow to execute.
-
-
-To remedy this, Game Maker has a number of built-in data
-structures that can be accessed through functions. At the moment
-there are six different types of data structure available: stacks,
-queues, lists, maps, priority queues, and grids. Each of these data structures
-is tuned for a particular type of use (see below).
-
-
-All data structures work globally in the same way. You can create a data
-structure with a function that returns an id for the structures. You use
-this id to perform operations on the data structures. Once you are done
-you destroy the data structure again to save storage. You can use as many
-of the structures at the same moment as you want. All structure can store
-both strings and real values.
-
-
-Please note that data structures and their content are not saved when you
-save the game using the actions or functions for that. If you use data
-structures and want to allow for saves you have to create your own mechanism
-for that.
-
-
-When comparing values, for example when searching in a map or sorting a list,
-Game Maker must decide when two values are equal. For strings and integer
-values this is clear but for real numbers, due to round-off errors, equal number
-can easily become unequal. For example (5/3)*3 will not be equal to 5. To avoid
-this, a precision is used. When the difference between two numbers is smaller
-than this precision they are considered equal. Default a precision of 0.0000001
-is used. You can change this precision using the following function:
-
-
-
- ds_set_precision(prec)
- Sets the precision used for comparisons.
-
-
-
-This precision is used in all data structures but not in other comparisons in GML!
-

Stacks
-
-A stack data structure is a so called LIFO (Last-In First-Out) structures. You can
-push values on a stack and the remove them again by popping them from the stack.
-The value that was pushed on the stack most recently is the first to be popped
-from it again. Stacks are often used when there are interrupts to handle, or
-when having recursive functions. The following functions exist for stacks:
-
-
-
- ds_stack_create()
- Creates a new stack. The function returns an integer as an id
- that must be used in all other functions to access the particular
- stack. You can create multiple stacks.
- ds_stack_destroy(id)
- Destroys the stack with the given id, freeing the memory used. Don't
- forget to call this function when you are ready with the structure.
- ds_stack_clear(id)
- Clears the stack with the given id, removing all data from it but
- not destroying it.
- ds_stack_copy(id,source)
- Copies the stack source into the stack with the given id.
- ds_stack_size(id)
- Returns the number of values stored in the stack.
- ds_stack_empty(id)
- Returns whether the stack is empty. This is the same as testing whether the size is 0.
- ds_stack_push(id,val)
- Pushes the value on the stack.
- ds_stack_pop(id)
- Returns the value on the top of the stack and removes it from the stack.
- ds_stack_top(id)
- Returns the value on the top of the stack but does not remove it from the stack.
- ds_stack_write(id)
- Turns the data structure into a string and returns this string. The string can then
- be used to e.g. save it to a file. This provides an easy mechanism for saving data
- structures.
- ds_stack_read(id,str)
- Reads the data structure from the given string (as created by the previous call).

Queues
-
-A queue is somewhat similar to a stack but it works on a FIFO
-(First-In First-Out) basis. The value that is put in the queue
-first is also the first to be removed from it. It works like
-a queue in a shop. The person who is first in a queue is served
-first. Queues are typically used to store things that still need to be
-done but there are many other uses. The following functions exist (note
-that the first five are equivalent to the functions for stacks; all
-data structures have these five functions):
-
-
-
- ds_queue_create()
- Creates a new queue. The function returns an integer as an id that
- must be used in all other functions to access the particular queue.
- You can create multiple queues.
- ds_queue_destroy(id)
- Destroys the queue with the given id, freeing the memory used.
- Don't forget to call this function when you are ready with the structure.
- ds_queue_clear(id)
- Clears the queue with the given id, removing all data from
- it but not destroying it.
- ds_queue_copy(id,source)
- Copies the queue source into the queue with the given id.
- ds_queue_size(id)
- Returns the number of values stored in the queue.
- ds_queue_empty(id)

- has most recently been added to the queue. (It does not remove it from the queue.)
- ds_queue_write(id)

- be used to e.g. save it to a file. This provides an easy mechanism for saving data
- structures.

Lists
-
-A list stores a collection of values in a particular order. You can add values
-at the end or insert them somewhere in the middle of the list. You can address
-the values using an index. Also you can sort the elements, either in ascending
-or descending order. Lists can be used in many ways, for example to store
-changing collections of values. They are implemented using simple arrays
-but, as this is done in compiled code it is a lot faster than using an

- ds_list_add(id,val)
- Adds the value at the end of the list.
- ds_list_insert(id,pos,val)
- Inserts the value at position pos in the list. The first position is
- 0, the last position is the size of the list minus 1.
- ds_list_replace(id,pos,val)
- Replaces the value at position pos in the list with the new value.
- ds_list_delete(id,pos)
- Deletes the value at position pos in the list. (Position 0 is the first element.)
- ds_list_find_index(id,val)
- Find the position storing the indicated value. If the value is not in the list -1 is returned.
- ds_list_find_value(id,pos)
- Returns the value stored at the indicated position in the list.
- ds_list_sort(id,ascend)
- Sorts the values in the list. When ascend is true the values are sorted
- in ascending order, otherwise in descending order.
- ds_list_shuffle(id)
- Shuffles the values in the list such that they end up in a random order.
- ds_list_write(id)
- Turns the data structure into a string and returns this string. The string can then
- be used to e.g. save it to a file. This provides an easy mechanism for saving data

Maps
-
-In quite a few situations you need to store pairs consisting of a key
-and a value. For example, a character can have a number of different
-items and for each item it has a particular number of those. In this
-case the item is the key and the number is the value. Maps maintain
-such pairs, sorted by key. You can add pairs to the map and search
-for the value corresponding to certain keys. Because the keys are
-sorted you can also find previous and next keys. Sometimes it is also
-useful to use a map to just store keys without a corresponding value.
-In that case you can simply use a value of 0. The following functions exist:
-
-
-
- ds_map_create()
- Creates a new map. The function returns an integer as an id that must be
- used in all other functions to access the particular map.
- ds_map_destroy(id)

- ds_map_find_value(id,key)
- Returns the value corresponding to the key.
- ds_map_find_previous(id,key)
- Returns the largest key in the map smaller than the indicated key. (Note

Grids
-
-A grid is simply a two-dimensional array. A grid has an integer width and
-height. The structure allows you to set and retrieve the value of cells in
-the grid by giving the index of it (which starts with 0 in both the x- and the
-y-direction). But you can also set the value in regions, add values, and retrieve
-the sum, max, min, and mean value over a region. The structure is useful to
-represent e.g. a playing field. Even though all functionality can also be
-achieved using two-dimensional arrays, the operations on regions are a
-lot faster. The following functions exist:
-
-
-
- ds_grid_create(w,h)
- Creates a new grid with the indicated width and height. The function returns an integer as
- an id that must be used in all other functions to access the particular
- grid.
- ds_grid_destroy(id)
- Destroys the grid with the given id, freeing the memory used.
- Don't forget to call this function when you are ready with the structure.
- ds_grid_copy(id,source)
- Copies the grid source into the grid with the given id.
- ds_grid_resize(id,w,h)

Creating particles
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Particle systems are meant to create special effects. Particles are small elements,
-represented by a little sprite.
-Such particles move around according to predefined rules and can change
-size, orientation, color, etc. while they move. Many such particles together can create e.g.
-fireworks, flames, explosions, rain, snow, star fields, flying debris, etc.
-
-
-Game Maker contains an extensive particle system that can be used
-to create great effects.
-Because of its generality it is not simple to use so better read
-this section carefully before trying.
-
-
-If this is too complicated for you, there is also a very simple mechanism
-to create different types of explosions, smoke, rain, and even fireworks.
-
-
-Particle systems have many parameters
-and it is not always easy to understand how to create the effects you want.
-First of all there are particle types. A particle type defines a particular
-kind of particles. Such types have many parameters that describe the
-shape, size, color, and motion of the particles. Particle types need to
-be defined only once and can then be used everywhere in the game.

-Secondly there are particle systems. There can be different particle systems
-in the game. A particle system can have particles of the different types.
-A particle system has emitters that create the particles, either
-continuously or in bursts. It can also have attractors that attract particles.
-Finally, it can have destroyers that destroy particles. Once particles are
-created in a particle system, they are automatically handled (updated and
-drawn) by the system.

Simple Effects
-
-The easiest way of creating particles is to use the effects mechanism.
-Effects are created using the particle system but you do not have to worry
-about all the details. You simply specify the type of effect, the position
-where it must be created, its size, and its color. That is all.
-
-
-There are a number of different kinds of effects:
-
-
-
ef_explosion
-
ef_ring
-
ef_ellipse
-
ef_firework
-
ef_smoke
-
ef_smokeup
-
ef_star
-
ef_spark
-
ef_flare
-
ef_cloud
-
ef_rain
-
ef_snow
-
-
-
-Some you want to create just once (like the explosion) and some you want to create in every step (like the
-smoke or the rain). Note that rain and snow are always created at the top of the room so the position
-is irrelevant in this case.
-
-
-Even though this might sound limited, they can actually be used to create great effects. For example
-by creating a smal puff of red smoke below a moving spaceship in each step, a tail of fire is created.
-The following two functions exist to create the effects:
-
-
-
- effect_create_below(kind,x,y,size,color)
- Creates an effect of the given kind (see above) at the
- indicated position. size give the size as follows: 0 = small,
- 1 = medium, 2 = large. color indicates the color to
- be used. The effect is created below the instances, that is,
- at a depth of 100000.
- effect_create_above(kind,x,y,size,color)
- Similar to the previous function but this time the
- effect is created on top of the instances, that is,
- at a depth of -100000.
-
-
-
-If you want to remove all effects, call the following function:
-
-
-
- effect_clear()
- Clears all effects.

Particle types
-
-A particle type describes the shape, color, motion, etc. of a particular kind of particles.
-You need to define a particle type only once in the game. After this it can be used in any
-particle system in the game. Particle types have a large number of parameters that can be used
-to change all aspects of it. Setting these right you can create almost any effect you like.
-We will discuss the settings below.
-
-
-A number of routines are available to create new particle types and destroy them again:
-
-
-
- part_type_create()
- Creates a new particle type. It returns the index of the type.
- This index must be used in all calls below to set the properties of the particle type.
- So you will often store it in a global variable.
- part_type_destroy(ind)
- Destroys particle type ind. Call this if you don't need it anymore to save space.
- part_type_exists(ind)
- Returns whether the indicated particle type exists.
- part_type_clear(ind)
- Clears the particle type ind to its default settings.
-
-
-
-
The shape of a particle
-
-A particle has a shape. This shape is indicated by a sprite. You can use any sprite you like
-for your particles but there are 15 built-in sprites. These are all 64x64 in size and have
-alpha values set such that they nicely blend with the background. They are
-indicate by the following constants:
-
-
-
pt_shape_pixel
-
pt_shape_disk
-
pt_shape_square
-
pt_shape_line
-
pt_shape_star
-
pt_shape_circle
-
pt_shape_ring
-
pt_shape_sphere
-
pt_shape_flare
-
pt_shape_spark
-
pt_shape_explosion
-
pt_shape_cloud
-
pt_shape_smoke
-
pt_shape_snow
-
-
-
-You set the shape using the following function:
-
-
-
- part_type_shape(ind,shape)
- Sets the shape of the particle type to any of the constants above (default is pt_shape_pixel).
-
-
-
-You can also use your own sprite for the particle. If the sprite has multiple subimages you can
-indicate what should be done with them. You can pick a random one, animate the sprite, start at
-the beginning of the animation or at a random place, etc. You use the following function for this.
-
-
-
- part_type_sprite(ind,sprite,animat,stretch,random)
- Sets your own sprite for the particle type. With animate you indicate whether
- the sprite should be animated (1) or not (0). With stretch (1 or 0) you indicate whether the
- animation must be stretched over the lifetime of the particle.
- And with random (1 or 0) you can indicate whether a random subimage must be choosen as starting image.
-
-
-
-Once you have choosen the sprite for the particle type (either a default shape or your own) you
-can indicate the size of it. A size of 1 indicates the normal size of the sprite.
-A particle type can be defined such that all particles have the
-same size or have different sizes. You can indicate a range of sizes. Also, you can indicate
-whether the size should change over the lifetime of the particle and whether some wiggling in
-the size will happen, giving a blinking effect.
-
-
-
- part_type_size(ind,size_min,size_max,size_incr,size_wiggle)
- Sets the size parameters for the particle type. You specify the minimum starting size,
- the maximum starting size, the size increase in each step (use a negative number for
- a decrease in size) and the amount of wiggling.
- (The default size is 1 and default the size does not change.)
- part_type_scale(ind,xscale,yscale)
- Sets the horizontal and vertical scale. This factor is multiplied with the size.
- It is in particular useful when you need to scale differently in x- and y-direction.
-
-
-
-The particles also have an orientation. Again the orientation can be the same for all
-particles, can be different, and can change over the lifetime of the sprite. The angles
-specify counter-clockwise rotations, in degrees.
-
-
-
- part_type_orientation(ind,ang_min,ang_max,ang_incr,ang_wiggle,ang_relative)
- Sets the orientation angle properties for the particle type. You specify the minimum
- angle, the maximum angle, the increase in each step and the amount of wiggling in angle.
- (Default all values are 0.) You can also indicate whether the given angle should be
- relative (1) to the current direction of motion or absolute (0). E.g. by setting
- all values to 0 but ang_relative to 1, the particle orientation will precisely follow
- the path of the particle.
-
-
-
-
Color and blending
-
-Particles will have a color. There are different ways in which you can specify colors for
-a particle. The simplest way is to indicate a single color. You can also specify two or three
-colors between which the color of the particle is interpolated during its life time. For example,
-the particle can start white and become more and more black over its lifetime. Another possibility
-is that you indicate that the color of each particle must be different, picked from a range of colors.
-You can either give a range in red, green and blue, or a range in hue, saturation, and value.
-
-
-Default the color is white. When you use a sprite with its own colors, this is normally what you
-want and no color needs to be specified.
-
-
-
- part_type_color1(ind,color1)
- Indicates a single color to be used for the particle.
- part_type_color2(ind,color1,color2)
- Specifies two colors between which the color is interpolated.
- part_type_color3(ind,color1,color2,color3)
- Similar but this time the color is interpolated between three colors that represent
- the color at the start, half-way, and at the end.
- part_type_color_mix(ind,color1,color2)
- With this function you indicate that the particle should get a color that is a random mixture
- of the two indicated colors. This color will remain fixed over the lifetime of the particle.
- part_type_color_rgb(ind,rmin,rmax,gmin,gmax,bmin,bmax)
- Can be used to indicate that each particle must have a fixed color but choosen from a range.
- You specify a range in the red, green, and blue component of the color (each between 0 and 255).
- part_type_color_hsv(ind,hmin,hmax,smin,smax,vmin,vmax)
- Can be used to indicate that each particle must have a fixed color but choosen from a range.
- You specify a range in the hue saturation and value component of the color (each between 0 and 255).
-
-
-
-Besides the color you can also give an alpha transparency value. The built-in particle shapes already
-have some alpha transparency but you can use these settings to e.g. make the particle vanish over its
-life time.
-
-
-
- part_type_alpha1(ind,alpha1)
- Sets a single alpha transparency parameter (0-1) for the particle type.
- part_type_alpha2(ind,alpha1,alpha2)
- Similar but this time a start and end value are given and the alpha value is interpolated between them.
- part_type_alpha3(ind,alpha1,alpha2,alpha3)
- This time three values are given between which the alpha transparency is interpolated.
-
-
-
-Normally particles are blended with the background in the same way as sprites. But it is also possible
-to use additive blending. This gives in particular a great effect for explosion.
-
-
-
- part_type_blend(ind,additive)
- Sets whether to use additive blending (1) or normal blending (0) for the particle type.
-
-
-
-
Life and death
-
-Particles live for a limited amount of time, their lifetime. After this they disappear. Lifetime is
-measured in steps. You can indicate the lifetime (or a range of lifetimes) for each particle type.
-Particles can create new particles of different types. There are two ways for this. They can create new particles in
-each step or they can create particles when they die. Be careful that the total number of
-particles does not get too high.
-
-
-
- part_type_life(ind,life_min,life_max)
- Sets the lifetime bounds for the particle type. (Default both are 100.)
- part_type_step(ind,step_number,step_type)
- Sets the number and type of particles that must be generated in each
- step for the indicated particle type. If you use a negative value,
- in each step a particle is generated with a chance -1/number.
- So for example with a value of -5 a particle is generated on average once every 5 steps.
- part_type_death(ind,death_number,death_type)
- Sets the number and type of particles that must be generated when a particle of the
- indicated type dies. Again you can use negative numbers to create a particle with
- a particular chance. Note that these particles are only created when the particle dies
- at the end of its life, not when it dies because of a destroyer (see below).
-
-
-
-
Particle motion
-
-Particles can move during their lifetime. They can get an initial speed (or range of speeds)
-and direction, and the speed and direction can change over time. Also gravity can be defined
-that pulls the particles in a particular direction. The following functions exist for this:
-
-
-
- part_type_speed(ind,speed_min,speed_max,speed_incr,speed_wiggle)
- Sets the speed properties for the particle type. (Default all values are 0.)
- You specify a minimal and maximal speed. A random value between the given bounds
- is chosen when the particle is created. You can indicate a speed increase in
- each step Use a negative number to slow the particle down (the speed will never
- become smaller than 0). Finally you can indicate some amount of wiggling of the speed.
- part_type_direction(ind,dir_min,dir_max,dir_incr,dir_wiggle)
- Sets the direction properties for the particle type. (Default all values are 0.)
- Again you specify a range of directions (in counterclockwise degrees;
- 0 indicated a motion to the right). For example, to let the particle move
- in a random direction choose 0 and 360 as values. You can specify an increase
- in direction for each step, and an amount of wiggling.
- part_type_gravity(ind,grav_amount,grav_dir)
- Sets the gravity properties for the particle type. (Default there is no gravity.)
- You specify the amount of gravity to be added in each step and the direction. E.g.
- use 270 for a downwards direction.

Particle systems
-
-Particles live in particle systems. So to have particles in your game you need
-to create one or more particle systems. There can be different particle
-systems (but preferably keep their number small).
-For example, if your game has a number of balls and each ball should
-have a tail of particles, most likely each ball has its own particle system.
-The easiest way to deal with particle systems is to create one and then
-create particles in it, using the particle types you specified before.
-But, as we will see below, particle systems can contain emitters that
-automatically produce particles, attractors that attract them, and
-destroyers that destroy them.
-
-
-Once particles are added to a particle system they are automatically
-updated each step and drawn. No further action is required. To make it possible
-that particles are drawn, behind, in front of, or between object instances,
-each particle system has a depth, similar to instances and tiles.
-
-
-Particle systems will live on forever after they are created. So even if
-you change room or restart the game, the systems and the particles remain.
-So you better make sure you destroy them once you no longer need them.
-
-
-The following basic functions deal with particle systems:
-
-
-
- part_system_create()
- Creates a new particle system. It returns the index of the system.
- This index must be used in all calls below to set the properties of
- the particle system.
- part_system_destroy(ind)
- Destroys the particle system ind. Call this if you don't need
- it anymore to save space.
- part_system_exists(ind)
- Returns whether the indicated particle system exists.
- part_system_clear(ind)
- Clears the particle system ind to its default settings, removing
- all particles and emitter and attractors in it.
- part_system_draw_order(ind,oldtonew)
- Sets the order in which the particle system draws the particles.
- When oldtonew is true the oldest particles are drawn first
- and the newer one lie on top of them (default). Otherwise the
- newest particles are drawn first. This can give rather different effects.
- part_system_depth(ind,depth)
- Sets the depth of the particle system. This can be used to let the
- particles appear behind, in front of, or in between instances.
- part_system_position(ind,x,y)
- Sets the position where the particle system is drawn. This is normally
- not necessary but if you want to have particles at a position relative
- to a moving object, you can set the position e.g. to that object.
-
-
-
-As indicated above, the particle system is automatically updated and drawn.
-But sometimes this is not what you want. To facilitate this, you can switch
-off automatic updating or drawing and then decide yourself when to update or
-draw the particle system. For this you can use the following functions:
-
-
-
- part_system_automatic_update(ind,automatic)
- Indicates whether the particle system must be updated
- automatically (1) or not (0). Default is 1.
- part_system_automatic_draw(ind,automatic)
- Indicates whether the particle system must be drawn
- automatically (1) or not (0). Default is 1.
- part_system_update(ind)
- This functions updates the position of all particles in the
- system and lets the emitters create particles.
- You only have to call this when updating is not automatic.
- (Although sometimes it is also useful to call this function
- a couple of time to get the system going.)
- part_system_drawit(ind)
- This functions draws the particles in the system.
- You only have to call this when drawing is not automatic.
- It should be called in the draw event of some object.
-
-
-
-The following functions deal with particles in a particle systems:
-
-
-
- part_particles_create(ind,x,y,parttype,number)
- This functions creates number particles of the indicated type at postion (x,y) in the system.
- part_particles_create_color(ind,x,y,parttype,color,number)
- This functions creates number particles of the indicated type at postion (x,y) in the system
- with the indicated color. This is only useful when the particle type defines a single color (or does
- not define a color at all).
- part_particles_clear(ind)
- This functions removes all particles in the system.
- part_particles_count(ind)
- This functions returns the number of particles in the system.

Emitters
-
-Emitters create particles. They can either create a continuous stream of
-particles or can burst out a number of particles when using the appropriate
-function. A particle system can have an arbitrary number of emitters.
-An emitter has the following properties:
-
-
-
xmin, xmax, ymin, ymax
- indicate the extend of the region in which the particles are generated.
-
shape
- indicates the shape of the region. It can have the following values:
-
-
ps_shape_rectangle
-
ps_shape_ellipse
-
ps_shape_diamond
-
ps_shape_line
-
-
distribution
- indicates the distribution used to generate the particles. It can have the following values:
-
-
ps_distr_linear
- indicates a linear distribution, that is everywhere in the region the chance is equal
-
ps_distr_gaussian
- indicates a Gaussian distribution in which more particles are generated
- in the center than at the sides of the region
-
ps_distr_invgaussian
- indicates an inverse Gaussian distribution in which more particles are generated
- at the sides of the region than in the center
-
-
particle type
- indicates the type of particles being generated
-
number
- indicates the number of particles generated in each step.
- If smaller than 0, in each step a particle is generated with a chance -1/number.
- So for example with a value of -5 a particle is generated on average once every 5 steps.
-
-

Attractors
-
-Besides emitters a particle system can also contain attractors.
-An attractor attracts the particles (or pushes them away).
-A particle system can have multiple attractors. You are though recommended
-to use few of these because they will slow down the processing of the
-particles. An attractor has the following properties:
-
-
-
x,y
- indicate the position of the attractor.
-
force
- indicates the attracting force of the attractor. How the force
- acts on the particles depends on the following parameters.
-
dist
- indicates the maximal distance at which the attractor has effect.
- Only particles closer that this distance to the attractor will be attracted.
-
kind
- indicates the kind of attractor. The following values exist
-
-
ps_force_constant
- indicates that the force is constant independent of the distance.
-
ps_force_linear
- indicates a linearly growing force. At the maximal distance the force
- is 0 while at the position of the attractor it attains the given value.
-
ps_force_quadratic
- indicates that the force grows quadratic.
-
-
additive
- indicates whether the force is added to the speed and direction in each
- step (true) or only applied to the position of the particle (false).
- When additive the particle will accelerate towards the attractor
- while with a non-additive force it will move there with constant speed.
-
-
-
-The following functions exist to define attractors. Note that each of them
-gets the index of the particle system to which it belongs as a first argument.
-
-
-
- part_attractor_create(ps)
- Creates a new attractor in the given particle system. It returns the index of the attractor.
- This index must be used in all calls below to set the properties of the attractor.
- part_attractor_destroy(ps,ind)
- Destroys attractor ind in the particle system.
- Call this if you don't need it anymore to save space.
- part_attractor_destroy_all(ps)
- Destroys all attractors in the particle system that have been created.
- part_attractor_exists(ps,ind)
- Returns whether the indicated attractor exists in the particle system.
- part_attractor_clear(ps,ind)
- Clears the attractor ind to its default settings.
- part_attractor_position(ps,ind,x,y)

Changers
-
-Changers change certain particles when they appear in their region.
-A particle system can have an arbitrary number of changers.
-A changer has the following properties:
-
-
-
xmin, xmax, ymin, ymax
- indicates the extent of the region in which the particles are changed.
-
shape
- indicates the shape of the region. It can have the following values:
-
-
ps_shape_rectangle
-
ps_shape_ellipse
-
ps_shape_diamond
-
-
parttype1
- indicates the particle type that is changed.
-
parttype2
- indicates the particle type into which it is changed.
-
kind
- indicates the kind of changer. It can have the following values:
-
-
ps_change_motion
- only changes the motion parameters of the particle, not the color and shape or lifetime settings.
-
ps_change_shape
- only changes the shape parameters like size and color and shape.
-
ps_change_all
- changes all parameters, this basically means that the particle is destroyed
- and a new one of the new type is created.

Firework Example
-
-Here is an example of a particle system that creates fireworks.
-The firework uses two particle types: one that forms the rocket
-and one that forms the actual fireworks. The rocket generates
-the firework particles when it dies. We also generate one
-emitter in the particle system that regularly stream out rocket
-particles along the bottom of the screen. To make this work you need an object.
-In its creation event we place the following code that creates
-the particle types, particle system, and the emitter:
-
-
-
-
-{
- // make the particle system
- ps = part_system_create();
-
- // the firework particles
- pt1 = part_type_create();
- part_type_shape(pt1,pt_shape_flare);
- part_type_size(pt1,0.1,0.2,0,0);
- part_type_speed(pt1,0.5,4,0,0);
- part_type_direction(pt1,0,360,0,0);
- part_type_color1(pt1,c_red);
- part_type_alpha2(pt1,1,0.4);
- part_type_life(pt1,20,30);
- part_type_gravity(pt1,0.2,270);
-
- // the rocket
- pt2 = part_type_create();
- part_type_shape(pt2,pt_shape_sphere);
- part_type_size(pt2,0.2,0.2,0,0);
- part_type_speed(pt2,10,14,0,0);
- part_type_direction(pt2,80,100,0,0);
- part_type_color2(pt2,c_white,c_gray);
- part_type_life(pt2,30,60);
- part_type_gravity(pt2,0.2,270);
- part_type_death(pt2,150,pt1); // create the firework on death
-
- // create the emitter
- em = part_emitter_create(ps);
- part_emitter_region(ps,em,100,540,480,490,ps_shape_rectangle,ps_distr_linear);
- part_emitter_stream(ps,em,pt2,-4); // create one every four steps
-}
-
-
-
-
-That will do the trick. You might want to make sure the particle system (and maybe particle types) are
-destroyed when moving to another room, otherwise the firework will continue forever.

Multiplayer games
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Playing games against the computer is fun. But playing games against other human players
-can be even more fun. It is also relatively easy to make such games because you don't have
-to implement complicated computer opponent AI. You can of course sit with two players
-behind the same monitor and use different keys or other input devices, but it is a lot
-more interesting when each player can sit behind his own computer. Or even better,
-one player sits on the other side of the ocean. Game Maker has multiplayer
-support. Please realize that creating effective multiplayer games that synchronize
-well and have no latency is a difficult task. This chapter gives a brief description
-of the possibilities. On the website a tutorial is available with more information.

Setting up a connection
-
-For two computer to communicate they will need some connection protocol.
-Like most games, Game Maker offers four different types of connections:
-IPX, TCP/IP, Modem, and Serial. The IPX connection (to be more precise,
-it is a protocol) is almost completely transparent. It can be used to
-play games with other people on the same local area network. It needs to
-be installed on your computer to be used. (If it does not work, consult
-the documentation of Windows. Or go to the Network item in the control
-panel of Windows and add the IPX protocol.) TCP/IP is the internet protocol.
-It can be used to play with other players anywhere on the internet,
-assuming you know their IP address. On a local network you can use it
-without providing addresses. A modem connection is made through the
-modem. You have to provide some modem settings (an initialization
-string and a phone number) to use it. Finally, when using a serial
-line (a direct connection between the computers) you need to provide
-a number of port settings. There are four GML functions that can be
-used for initializing these connections:
-
-
-
- mplay_init_ipx()
- initializes an IPX connection.
- mplay_init_tcpip(addr)
- initializes a TCP/IP connection. addr is a string containing the web
- address or IP address, e.g. 'www.gameplay.com' or '123.123.123.12',
- possibly followed by a port number (e.g. ':12'). Only when joining a
- session (see below) do you need to provide an address. On a local
- area network no addresses are necessary.
- mplay_init_modem(initstr,phonenr)
- initializes a modem connection. initstr is the initialization
- string for the modem (can be empty). phonenr is a string that
- contains the phone number to ring (e.g. '0201234567'). Only when
- joining a session (see below) do you need to provide a phone number.
- mplay_init_serial(portno,baudrate,stopbits,parity,flow)
- initializes a serial connection. portno is the port number (1-4).
- baudrate is the baudrate to be used (100-256K). stopbits indicates
- the number of stopbits (0 = 1 bit, 1 = 1.5 bit, 2 = 2 bits). parity
- indicates the parity (0=none, 1=odd, 2=even, 3=mark). And flow indicates
- the type of flow control (0=none, 1=xon/xoff, 2=rts, 3=dtr, 4=rts and dtr).
- Returns whether successful. A typical call is mplay_init_serial(1,57600,0,0,4).
- Give 0 as a first argument to open a dialog for the user to change the settings.
-
-
-
-Your game should call one of these functions exactly once. All functions report
-whether they were successful. They are not successful if the particular protocol
-is not installed or supported by your machine. To check whether there is a
-successful connection available you can use the following function
-
-
-
- mplay_connect_status()
- returns the status of the current connection. 0 = no connection,
- 1 = IPX connection, 2 = TCP/IP connection, 3 = modem connection,
- and 4 = serial connection.
-
-
-
-To end the connection call
-
-
-
- mplay_end()
- ends the current connection.
-
-
-
-When using a TCP/IP connection you might want to tell the person you want to play
-the game with what the ip address of your computer is. The following function helps you here:
-
-
-
- mplay_ipaddress()
- returns the IP address of your machine (e.g. '123.123.123.12') as a
- string. You can e.g. display this somewhere on the screen. Note that
- this routine is slow so don't call it all the time.

Creating and joining sessions
-
-When you connect to a network, there can be multiple games happening on the same
-network. We call these sessions. These different sessions can correspond to
-different games or to the same game. A game must uniquely identify itself
-on the network. Fortunately, Game Maker does this for you. The only
-thing you have to know is that when you change the game id in the options
-form this identification changes. In this way you can avoid that people with
-old versions of your game will play against people with new versions.
-
-
-If you want to start a new multiplayer game you need to create a new session.
-For this you can use the following routine:
-
-
-
- mplay_session_create(sesname,playnumb,playername)
- creates a new session on the current connection. sesname is a string
- indicating the name of the session. playnumb is a number that indicates
- the maximal number of players allowed in this game (use 0 for an arbitrary
- number). playname is your name as player. Returns whether successful.
-
-
-
-One instance of the game must create the session. The other instance(s)
-of the game should join this session. This is slightly more complicated.
-You first need to look at what sessions are available and then choose the
-one to join. There are three important routines for this:
-
-
-
- mplay_session_find()
- searches for all sessions that still accept players and returns
- the number of sessions found.
- mplay_session_name(numb)
- returns the name of session number numb (0 is the first session).
- This routine can only be called after calling the previous routine.
- mplay_session_join(numb,playername)
- makes you join session number numb (0 is the first session).
- playername is your name as a player. Returns whether successful.
-
-
-
-There is one more routine that can change the session mode.
-It should be called before creating a session:
-
-
-
- mplay_session_mode(move)
- sets whether or not to move the session host to another computer when
- the host ends. move should either be true or false (the default).
-
-
-
-To check the status of the current session you can use the following function
-
-
-
- mplay_session_status()
- returns the status of the current session. 0 = no session,
- 1 = created session, 2 = joined session.
-
-
-
-A player can stop a session using the following routine:
-
-
-
- mplay_session_end()
- ends the session for this player.

Shared data
-
-Shared data communication is probably the easiest way to synchronize
-the game. All communication is shielded from you. There is a set of
-1000000 values that are common to all entities of the game (preferably
-only use the first few to save memory). Each entity can set values and
-read values. Game Maker makes sure that each entity sees
-the same values. A value can either be a real or a string. There
-are just two routines:
-
-
-
- mplay_data_write(ind,val)
- write value val (string or real) into location ind (ind between 0 and 1000000).
- mplay_data_read(ind)
- returns the value in location ind (ind between 0 and 1000000). Initially all values are 0.
-
-
-
-To synchronize the data on the different machines you can either use a
-guaranteed mode that makes sure that the change arrives on the other machine
-(but which is slow) or non-guaranteed. To change this use the following routine:
-
-
-
- mplay_data_mode(guar)
- sets whether or not to use guaranteed transmission for
- shared data. guar should either be true (the default) or false.

Messages
-
-The second communication mechanism that Game Maker supports
-is the sending and receiving of messages. A player can send messages
-to one or all other players. Players can see whether messages have
-arrived and take action accordingly. Messages can be sent in a
-guaranteed mode in which you are sure they arrive (but this can be
-slow) or in a non-guaranteed mode, which is faster.
-
-
-The following messaging routines exist:
-
-
-
- mplay_message_send(player,id,val)
- sends a message to the indicated player (either an identifier
- or a name; use 0 to send the message to all players). id is an
- integer message identifier and val is the value (either a real
- or a string). The message is sent in non-guaranteed mode. If val
- contains a string the maximal string length allowed is 30000 characters.
- mplay_message_send_guaranteed(player,id,val)
- sends a message to the indicated player (either an identifier
- or a name; use 0 to send the message to all players). id is an
- integer message identifier and val is the value (either a real
- or a string). This is a guaranteed send. If val contains a string
- the maximal string length allowed is 30000 characters.
- mplay_message_receive(player)
- receives the next message from the message queue that came from
- the indicated player (either an identifier or a name). Use 0 for
- messages from any player. The routine returns whether there was
- indeed a new message. If so you can use the following routines
- to get its contents:
- mplay_message_id()
- Returns the identifier of the last received message.
- mplay_message_value()
- Returns the value of the last received message.
- mplay_message_player()
- Returns the player who sent the last received message.
- mplay_message_name()
- Returns the name of the player who sent the last received message.
- mplay_message_count(player)
- Returns the number of messages left in the queue from the player (use 0 to count all message).
- mplay_message_clear(player)
- Removes all messages left in the queue from the player (use 0 to remove all message).
-
-
-
-A few remarks are pertinent here. First of all, if you want to send a message
-to a particular player only, you will need to know the player's unique id.
-As indicated earlier you can obtain this with the function mplay_player_id().
-This player identifier is also used when receiving messages from a particular
-player. Alternatively, you can give the name of the player as a string.
-If multiple players have the same name, only the first will get the message.
-
-
-Secondly, you might wonder why each message has an integer identifier.
-The reason is that this helps your application to send different types of
-messages. The receiver can check the type of message using the id and take
-appropriate actions. (Because messages are not guaranteed to arrive,
-sending id and value in different messages would cause serious problems.)

Using DLL's
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-
-Please note that since version 7 there is a new extension mechanism in Game Maker.
-You are strongly encouraged to use that extension mechanism, rather than the functions
-described in this section.
-See
-http://www.yoyogames.com/extensions
-for details.
-These functions are mainly left in for compatibility
-with the past.
-
-
-
-In those cases were the functionality of GML is not enough for your wishes,
-you can actually extend the possibilities by using plug-ins. A plug-in comes
-in the form of a DLL file (a Dynamic Link Library). In such a DLL file you
-can define functions. Such functions can be programmed in any programming
-language that supports the creation of DLL's (e.g. Delphi, C, C++, etc.)
-You will though need to have some programming skill to do this. Plug-in
-functions must have a specific format. They can have between 0 and 16
-arguments, each of which can either be a real number (double in C) or
-a null-terminated string. (For more than 4 arguments, only real
-arguments are supported at the moment.) They must return either
-a real or a null-terminated string.
-
-
-In Delphi you create a DLL by first choosing New
-from the File menu and then choosing DLL. Here
-is an example of a DLL you can use with Game Maker
-written in Delphi. (Note that this is Delphi code,
-not GML code!)
-
-
-
-
-library MyDLL;
-
-uses SysUtils, Classes;
-
-function MyMin(x,y:double):double; cdecl;
-begin
- if x<y then Result := x else Result := y;
-end;
-
-var res : array[0..1024] of char;
-
-function DoubleString(str:PChar):PChar; cdecl;
-begin
- StrCopy(res,str);
- StrCat(res,str);
- Result := res;
-end;
-
-exports MyMin, DoubleString;
-
-begin
-end.
-
-
-
-
-This DLL defines two functions: MyMin that takes two real arguments
-and returns the minimum of the two, and DoubleString that
-doubles the string. Note that you have to be careful with memory
-management. That is why I declared the resulting string global.
-Also notice the use of the cdecl calling convention. You can
-either use cdecl or stdcall calling conventions. Once you build
-the DLL in Delphi you will get a file MyDLL.DLL. This
-file must be placed in the running directory of your game.
-(Or any other place where Windows can find it.)
-
-
-To use this DLL in Game Maker you first need to specify the
-external functions you want to use and what type of arguments they
-take. For this there is the following function in GML:
-
-
-
- external_define(dll,name,calltype,restype,argnumb,arg1type,arg2type, ...)
- Defines an external function. dll is the name of the dll file.
- name is the name of the functions. calltype is the calling convention
- used. For this use either dll_cdecl or dll_stdcall. restype is the
- type of the result. For this use either ty_real or ty_string. argnumb
- is the number of arguments (0-16). Next, for each argument you must
- specify its type. For this again use either ty_real or ty_string.
- When there are more than 4 arguments all of them must be of type ty_real.
-
-
-
-This function returns the id of the external function that
-must be used for calling it. So in the above example, at the
-start of the game you would use the following GML code:
-
-
-Now whenever you need to call the functions, you use the following function:
-
-
-
- external_call(id,arg1,arg2,...)
- Calls the external function with the given id, and the given
- arguments. You need to provide the correct number of arguments
- of the correct type (real or string). The function returns
- the result of the external function.
-
-If you don't need to use the DLL anymore you had better free it.
-
-
-
- external_free(dll)
- Frees the DLL with the given name. This is in particular necessary if the
- game should remove the DLL. As long as the DLL is not freed it cannot be
- removed. Best do this e.g. in an end of game event.
-
-
-
-You might wonder how to make a function in a DLL that does
-something in the game. For example, you might want to create
-a DLL that adds instances of objects to your game. The easiest
-way is to let your DLL function return a string that
-contains a piece of GML code. This string that contains
-the piece of GML can be executed using the GML function
-
-
-
- execute_string(str,arg0,arg1,...)
- Execute the piece of code in the string str with the indicated arguments.
-
-
-
-Alternatively you can let the DLL create a file with a
-script that can be executed (this function can also be
-used to later modify the behavior of a game).
-
-
-
- execute_file(fname)
- Execute the piece of code in the file.
-
-
-
-Now you can call an external function and then execute the resulting string, e.g. as follows:
-
-
-In some rare cases your DLL might need to know the handle of the main
-graphics window for the game. This can be obtained with the following
-function and can then be passed to the DLL:
-
-
-
- window_handle()
- Returns the window handle for the main window.
-
-
-
-Note that DLLs cannot be used in secure mode.
-
-
-Using external DLLs is an extremely powerful mechanism.
-But please only use it if you know what you are doing.

3D Graphics
-
-This functionality is only available in the Pro Edition of Game Maker.
-
-
-Game Maker is a program meant for making 2-dimensional and isometric games. Still
-there is some functionality to create 3-dimensional graphics. Before you start with this though
-there are a few things you must understand.
-
-
-
The 3D functionality in Game Maker is limited to the graphics part. There is
- no support for other 3D functionality. Once you start using 3D graphics you might
- get problems with other aspects of Game Maker, like the views,
- depth ordering, etc. The functionality is limited and has low priority to
- be extended. So don't expect support for 3D object models, etc.
-
When you use the 3D functionality, there are a number of other things that can no
- longer be used.
-
-
You cannot use background and foregrounds in your rooms
- anymore. (The reason is that they are tiled to fill the image but with perspective
- projections this no longer work correctly).
-
You cannot use the mouse position anymore. The mouse will not be transformed to the
- 3D coordinates. You can still get the position of the mouse on the screen (in the view)
- but you will have to do calculation with this yourself (or not use the mouse at all).
-
You cannot use tiles anymore. Tiles will most likely no longer match up correctly.
-
Collision checking still uses the 2-d positions of the instances in the room. So there
- is no collision detection in 3D. Sometimes you can still use this (if you use the room
- as a representation of a flat world (e.g. for racing or FPS games) but in other situations
- you have to do things yourself.
-
-
All 3D functionality is through code. You must be rather fluent with the GML language.
- Also you must really understand a lot about how Game Maker works otherwise you will
- run into trouble.
-
You must have some basic knowledge about 3D graphics. In particular I will use terms
- like perspective projections, hidden surface removal, lighting, and fog, without much
- explanation.
-
There is no 3D modelling in Game Maker. Also I do not plan on adding support
- for loading 3D models.
-
You must work carefully to keep a reasonable speed. Also, things are not really
- optimized for speed.
-
-
-
-If this did not discourage you, read on.

Going to 3D mode
-
-If you want to use 3D mode you first need to set Game Maker in 3D mode. You can later
-switch back to 2D mode if you want. The following two functions exist for this.
-
-
-
- d3d_start()
- Start using 3D mode. Returns whether successful.
- d3d_end()
- Stop using 3D mode. Returns whether successful.
-
-
-
-Note that all functions related to 3D mode start with d3d_.
-
-
-Starting 3D mode will result in the following changes. First of all hidden surface removal
-is switched on (using a 16-bit z-buffer). This means that for each pixel on the screen
-only the drawing with the smallest z-value (= depth value) is drawn. If instances have the
-same depth it is unclear what will happen and you can get ugly effects. Make sure instances
-that might overlap do not have the same depth value!
-
-
-Secondly, the normal orthographic projection is replaced by a perspective one. This means the
-following. Normally the size of instances on the screen is independent on its depth. With a
-perspective projection instances that have a greater depth will appear smaller. When the depth
-is 0 it is equal to the old size (unless you change the projection; see below). The viewpoint
-for the camera is placed at a distance above the room. (This distance is equal to the width
-of the room; that gives a reasonable default projection.) Only instances in front of the camera
-are drawn. So don't use instances with a depth smaller than 0 (or at least not smaller than -w
-where w is the width of the room or the view).
-
-
-Thirdly, the vertical y-coordinate is reversed. While normally the (0,0) position is at the top-left
-of the view, in 3D mode the (0,0) position is at the bottom-left position, as is normal for
-3-dimensional views.
-
-
-You can actually switch hidden surface remove and perspective projection on or off using the
-following functions.
-
-
-
- d3d_set_hidden(enable)
- Enables hidden surface removal (true) or disables it (false).
- d3d_set_perspective(enable)
- Enables the use of a perspective projection (true) or disables it (false).

Easy drawing
-
-Once 3D mode has been switched on you can use Game Maker as you are used to it (except
-for the remarks made at the beginning). Only objects will appear in different sizes based on
-their depth setting. You can even use views. One additional function can be useful. If you
-draw a number of things in a piece of code you might want to change the depth value between
-the primitives you draw. For this you use:
-
-
-
- d3d_set_depth(depth)
- Sets the depth used for drawing.
-
-
-
-Note that at the moment a new instance is drawn the depth is again set to the depth of that
-instance.

Drawing polygons in 3D
-
-The problem with drawing in the old way is that a sprite or polygon always lies in the xy-plane,
-that is, all corners have the same depth. For true 3D you want to be able to have vertices
-at different depths. From this moment on we will talk about z-coordinate rather than depth.
-So we want to specify coordinates as (x,y,z) tuples. For this there are special version of
-the advanced drawing functions:
-
-
-
- d3d_primitive_begin(kind)
- Start a 3D primitive of the indicated kind: pr_pointlist, pr_linelist,
- pr_linestrip,pr_trianglelist,pr_trianglestrip or pr_trianglefan.
- d3d_vertex(x,y,z)
- Add vertex (x,y,z) to the primitive, using the color and alpha value set before.
- d3d_vertex_color(x,y,z,col,alpha)
- Add vertex (x,y,z) to the primitive, with its own color and alpha
- value. This allows you to create primitives with smoothly changing color and alpha values.
- d3d_primitive_end()
- End the description of the primitive. This function actually draws it.
-
-
-
-For example, to draw a tetrahedron (three sided pyramid) standing on the z=0 plane
-with its top at z = 200, you can use the following code:
-
-
-Now if you would use this, most likely you would just see a triangle on the screen
-because the top of the tetrahedron will be behind it from the viewpoint. Also, using just one color,
-it would be difficult to see the different faces. Below we will see ways to change
-the viewpoint. Assigning colors can be done as before by added draw_set_color(col)
-function calls between the vertices.
-
-
-You can also use textured poygons in 3D. It works exactly the same as described in the
-advanced drawing functions in the documentation. But this time you need 3D variants
-of the basic functions. One thing you must realize. In a texture the position (0,0) is the
-top-left corner. But often, when using projections (as indicated below), the bottom-left
-corner is (0,0). In such a case you might need to flip the texture vertically.
-
-
-
- d3d_primitive_begin_texture(kind,texid)
- Start a 3D primitive of the indicated kind with the given texture.
- d3d_vertex_texture(x,y,z,xtex,ytex)
- Add vertex (x,y,z) to the primitive with position (xtex,ytex) in the
- texture, blending with the color and alpha value set before.
- d3d_vertex_texture_color(x,y,z,xtex,ytex,col,alpha)
- Add vertex (x,y,z) to the primitive with position
- (xtex,ytex) in the texture, blending with its own color and alpha value.
- d3d_primitive_end()
- End the description of the primitive. This function actually draws it.
-
-
-
-So, for example you can use the following code to draw a background image that
-disappears into the distance
-
-
-A triangle has a front and a back side. The front side is defined to be the side where the vertices are
-defined in counter-clockwise order. Normally both sides are drawn. But if you make a closed shape this
-is a waste because the back side of the triangle can never be seen. In this case you can switch on
-backface culling. This saves about half the amount of drawing time but it leaves you with the task of
-defining your polygons in the right way. The following function exists:
-
-
-
- d3d_set_culling(cull)
- Indicates to start backface culling (true) or stop backface culling (false).

Viewing the world
-
-Default you look along the negative z-axis toward the middle of the room. Often in 3D games
-you want to change how you look at the world. For example, in a first person shooter you probably
-want to have the camera look from a position a bit above the xy-plane along the xy-plane. In
-graphics terms you are setting the correct projection. To change
-the way you look the following two functions exist.
-
-
-
- d3d_set_projection(xfrom,yfrom,zfrom,xto,yto,zto,xup,yup,zup)
- Defines how to look in the world. You specify the point to
- look from, the point to look to and the up vector.
-
-
-
-This function requires some explanation. To set the projection you first need the
-position you look from. This is indicated by the parameters (xfrom,yfrom,zfrom).
-Next you must specify the direction you look in. This is done by giving a second point
-to look towards. This is the point (xto,yto,zto). Finally, you can still rotate
-the camera around the line from the viewpoint to the looking point. To specify this we
-must give an up vector, that is, the direction that is upwards in the camera. This
-is given by the last three parameters (xup,yup,zup). Let me given an example.
-To look along the xy-plane as in a first person shooter you can use
-
-
-
-So you look from point (100,100) and 10 above the plane in the direction of (200,100). The up vector
-points is the z-direction as required. To make this slightly more complicated, assume you have an
-instance in your room that specifies the position of the camera. It will have a current (x,y) position
-and a direction (and maybe even a speed). You can now specify this as your camera by using the
-following code:
-
-
-This might look a bit complicated. We look from the camera position (x,y), 10 above the ground.
-To determine a point in the correct direction we need to do a little arithmetic. This point
-is indicated by the next three parameters. Finally we use the up vector as above.
-
-
-One important remark! When Game Maker starts drawing a room it will set the view point
-back to the default position. So the first thing you must do when drawing the scene is set
-is to the projection you want. This must be done in a drawing event!
-
-
-There is also an extended version of the function above:
-
-
-
- d3d_set_projection_ext(xfrom,yfrom,zfrom,xto,yto,zto,xup,yup,zup,angle,aspect,znear,zfar)
- An extended version of this function in which you also specify the
- angle defining the field of view, the aspect ratio between horizontal
- and vertical size of the view, and the near and far clipping planes.
-
-
-
-The additional parameters work as follows. If you specified the camera position, point to look at,
-and up vector, you can still change how wide the lens of the camera is. This is called the
-field of view. A reasonable value is somewhere between 40 and 45 degrees. But you can
-change this if you like. Next you can specify the aspect ratio between the horizontal and vertical
-projection. Normally you want to use the same as the aspect ration of the room or view, e.g. 640/480.
-Finally you can indicate the clipping planes. Objects that are closer than znear to the
-camera are not drawn. Similar for objects further than zfar. It can be important to
-set these parameters to reasonable values because they also influence the precision of the
-z-comparisons. If you make the range too large the precision gets worse. Default we use 1 and 32000.
-znear must be larger than 0!
-
-
-
-Sometimes you temporarily need a normal orthographic projection as is used when there is no
-3D. Or you want to return to the default perspective projection.
-For this you can use the following functions:
-
-
-
- d3d_set_projection_ortho(x,y,w,h,angle)
- Sets a normal orthographic projection of the indicated area in the
- room, rotated over the indicated angle.
- d3d_set_projection_perspective(x,y,w,h,angle)
- Sets a normal perspective projection of the indicated area in the
- room, rotated over the indicated angle.
-
-
-
-A standard use for this is to draw an overlay to e.g. show the score or other aspects. To
-do so we set an orthographic projection. We also must temporarily switch off hidden surface
-removal cause we want the information to be drawn regardless of the current depth value. The
-following example shows how to create an overlay with the score.

Transformations
-
-Transformation allow you to change the place where things are drawn in the world. For
-example, the function to draw blocks can only draw axis-parallel blocks. By first setting
-a rotation transformation you can create rotated blocks. Also sprites are always drawn
-parallel to the xy-plane. By setting a transformation you can change this. There are
-two types of functions: functions that set the transformation and functions that add
-transformations.
-
-
-
-
- d3d_transform_set_identity()
- Sets the transformation to the identity (no transformation).
- d3d_transform_set_translation(xt,yt,zt)
- Sets the transformation to a translation over the indicated vector.
- d3d_transform_set_scaling(xs,ys,zs)
- Sets the transformation to a scaling with the indicated amounts.
- d3d_transform_set_rotation_x(angle)
- Sets the transformation to a rotation around the x-axis with the indicated amount.
- d3d_transform_set_rotation_y(angle)
- Sets the transformation to a rotation around the y-axis with the indicated amount.
- d3d_transform_set_rotation_z(angle)
- Sets the transformation to a rotation around the z-axis with the indicated amount.
- d3d_transform_set_rotation_axis(xa,ya,za,angle)
- Sets the transformation to a rotation around the axis indicated by the vector
- with the indicated amount.
- d3d_transform_add_translation(xt,yt,zt)
- Adds a translation over the indicated vector.
- d3d_transform_add_scaling(xs,ys,zs)
- Adds a scaling with the indicated amounts.
- d3d_transform_add_rotation_x(angle)
- Adds a rotation around the x-axis with the indicated amount.
- d3d_transform_add_rotation_y(angle)
- Adds a rotation around the y-axis with the indicated amount.
- d3d_transform_add_rotation_z(angle)
- Adds a rotation around the z-axis with the indicated amount.
- d3d_transform_add_rotation_axis(xa,ya,za,angle)
- Adds a rotation around the axis indicated by the vector
- with the indicated amount.
-
-
-Realize that rotation and scaling are with respect to the origin of the world, not with
-respect to the object that is to be drawn. If the object is not at the origin it will
-also move to a different place, which is not what we want. So to e.g. rotate an object over
-its own x-axis, we must first translate it to the origin, next rotate it, and finally
-translate it back to its position. This is what the functions to add transformations are
-for.
-
-
-The following examples might explain this better. Assume we have a sprite spr that we
-want to draw at position (100,100,10). We can use the following code to do this
-
-
-Note that because we use a translation we should now draw the sprite at position (0,0). (This
-assumes the current instance has a depth of 0! If you are not sure, first set the depth.) If we
-would use this in our first person shooter we would not see the sprite. The reason is that it
-is still parallel to the xy-plane. We want to rotate it over 90 degrees along the x-axis
-(or y-axis). So we need to add a rotation. Remember the order: we must first rotate the
-sprite and then translate it. So we can use the following code.
-
-
-Sometimes you temporarily want to save the current transformation, for example to add
-an additional transformation and then restore the old one (this often happens when
-drawing hierarchical models). To this end you can push the current transformation on a
-stack and later pop it from the stack to make it the current transformation again. The
-following functions exist for this:
-
-
-
- d3d_transform_stack_clear()
- Clears the stack of transformations.
- d3d_transform_stack_empty()
- Returns whether the transformation stack is empty.
- d3d_transform_stack_push()
- Pushes the current transformation on the stack. Returns whether there was
- room on the stack to push it there (if you forget popping transformation
- you at some moment will run out of room on the stack).
- d3d_transform_stack_pop()
- Pops the top transformation from the stack and makes it the current one.
- Returns whether there was a transformation on the stack.
- d3d_transform_stack_top()
- Makes the top transformation the current one, but does not remove it from the stack.
- Returns whether there was a transformation on the stack.
- d3d_transform_stack_discard()
- Removes the top transformation from the stack but does not make it the current one.
- Returns whether there was a transformation on the stack.
-
-
-
-Using transformation is a powerful mechanism. But be careful and always set the transformation
-back to the identity once you are done.

Fog
-
-Fog can be used in 3D games to make objects in the distance look blurred or even disappear.
-This helps in creating atmosphere and it makes it possible to not draw objects that are
-far away. To enable or disable fog use the following function:
-
-
-
- d3d_set_fog(enable,color,start,end)
- Enables or disables the use of fog. color indicates the fog color.
- start indicates the distance at which fog must start. end
- indicates the distance at which fog is maximal and nothing can be seen anymore.
-
-
-
-To better understand what is happening, there are actually two types of fog, table based fog
-and vertex based fog. The first type calculates fog values on a pixel basis. The second type
-calculates the fog value for each vertex and then interpolates these. The first type is better
-but not always supported. Game Maker tries to use table based fog when supported and
-otherwise uses vertex based fog (unless no fog is supported). Note that certain graphics
-card indicate that they can handle table based fog but offer the user the possibility to
-switch this off in the advanced display settings. In this case the result might be a black
-screen!

Lighting
-
-Scenes you draw with the functions above look rather flat because there is no light. The color
-if the faces is equal, independent of their orientation. To create more realistically looking
-scenes you must enable lighting and place lights at the correct places.
-Creating correctly lit scenes is not easy but the
-effect is very good.
-
-
-To enable lighting you can use the following function;
-
-
-
- d3d_set_lighting(enable)
- Enables or disables the use of lighting.
-
-
-
-When using lighting, for each vertex of a polygon the color is determined. Next, the color
-of internal pixels is based on the color of these vertices. There are two ways this can be done:
-Either the whole polygon gets the same color, or the color is smoothly interpolated over the
-polygon. Default smooth shading is used. This can be changed using the following function:
-
-
-
- d3d_set_shading(smooth)
- Set whether to use smooth shading or not.
-
-
-
-To use lighting you obviously need to define lights. Two different lights exist: directional lights
-(like the sun), and positional lights. Light have a color. (We only support diffuse light,
-not specular reflection.)
-The following functions exist to define and use lights:
-
-
-
- d3d_light_define_direction(ind,dx,dy,dz,col)
- Defines a directed light. ind is the index of the light (use a small
- positive number). (dx,dy,dz) is the direction of the light. col is the
- color of the light (often you want to use c_white.
- This function does not turn the light on.
- d3d_light_define_point(ind,x,y,z,range,col)
- Defines a point light. ind is the index of the light use a small
- positive number). (x,y,z) is the position of the light. range
- indicates till how far the light shines. The intensity of the light
- will decrease over this range. col is the color
- of the light. This function does not turn the light on.
- d3d_light_enable(ind,enable)
- Enables (true) or disables (false) light number ind.
-
-
-
-The way an object reflects light depends on the angle between the light direction and the normal
-of the surface, that is, the vector pointing away from the surface. Hence, to create lighted objects
-you need not only provide the position of the vertices but also
-their normals. For this four additional functions are avaliable to define the vertices of
-primitives:
-
-
-
- d3d_vertex_normal(x,y,z,nx,ny,nz)
- Add vertex (x,y,z) to the primitive, with normal vector (nx,ny,nz).
- d3d_vertex_normal_color(x,y,z,nx,ny,nz,col,alpha)
- Add vertex (x,y,z) to the primitive, with normal vector (nx,ny,nz),
- and with its own color and alpha value.
- d3d_vertex_normal_texture(x,y,z,nx,ny,nz,xtex,ytex)
- Add vertex (x,y,z) to the primitive, with normal vector (nx,ny,nz),
- and with position (xtex,ytex) in the
- texture, blending with the color and alpha value set before.
- d3d_vertex_normal_texture_color(x,y,z,nx,ny,nz,xtex,ytex,col,alpha)
- Add vertex (x,y,z) to the primitive, with normal vector (nx,ny,nz), and with position
- (xtex,ytex) in the texture, blending with its own color and alpha value.
-
-
-
-Note that for the basic shapes that you can draw the normals are automatically set correctly.

Creating models
-
-When you need to draw large models it is rather expensive to call all the different drawing
-functions again and again in every step. To avoid this you can create models. A model consists
-of a number of drawing primitives and shapes. Once a model is created you can draw it at
-different places with just one function call. Models can also be loaded from a file or saved
-to a file.
-
-
-Before giving the different functions available there is one important point: the handling of
-textures. As described earlier, texture are taken from sprites and backgrounds. The indices
-of the textures can be different at different moments. As a result models do not contain any
-texture information. Only when you draw a model you provide the texture. So you can only use
-one texture in a model. If you need more textures you must either combine them in one (and
-carefully deal with the texture coordinates) or you must use multiple models. The advantage
-of this is that you can draw the same model easily with different textures.
-
-
-For creating, loading, saving, and drawing models, the following functions exist:
-
-
-
- d3d_model_create()
- Creates a new model and returns its index. This index is used in all
- other functions dealing with models.
- d3d_model_destroy(ind)
- Destroys the model with the given index, freeing its memory.
- d3d_model_clear(ind)
- Clears the model with the given index, removing all its primitives.
- d3d_model_save(ind,fname)
- Saves the model to the indicated file name.
- d3d_model_load(ind,fname)
- Loads the model from the indicated file name.
- d3d_model_draw(ind,x,y,z,texid)
- Draws the model at position (x,y,z). texid is the texture that
- must be used. Use -1 if you do not want to use a texture. If you want to
- rotate or scale the model you can use the transformation routines
- described before.
-
-
-
-For each primitive function there is an equivalent to add it to a model. The functions
-have the same arguments as before except that each has a first argument the index of
-the model, and no texture information is provided.
-
-
-
- d3d_model_primitive_begin(ind,kind)
- Adds a 3D primitive to the model of the indicated kind: pr_pointlist, pr_linelist,
- pr_linestrip,pr_trianglelist,pr_trianglestrip or pr_trianglefan.
- d3d_model_vertex(ind,x,y,z)
- Add vertex (x,y,z) to the model.
- d3d_model_vertex_color(ind,x,y,z,col,alpha)
- Add vertex (x,y,z) to the model, with its own color and alpha value.
- d3d_model_vertex_texture(ind,x,y,z,xtex,ytex)
- Add vertex (x,y,z) to the model with position (xtex,ytex) in the texture.
- d3d_model_vertex_texture_color(ind,x,y,z,xtex,ytex,col,alpha)
- Add vertex (x,y,z) to the model with texture and color values.
- d3d_model_vertex_normal(ind,x,y,z,nx,ny,nz)
- Add vertex (x,y,z) to the model, with normal vector (nx,ny,nz).
- d3d_model_vertex_normal_color(ind,x,y,z,nx,ny,nz,col,alpha)
- Add vertex (x,y,z) to the model, with normal vector (nx,ny,nz),
- and with its own color and alpha value.
- d3d_model_vertex_normal_texture(ind,x,y,z,nx,ny,nz,xtex,ytex)
- Add vertex (x,y,z) to the model, with normal vector (nx,ny,nz),
- with texture position.
- d3d_model_vertex_normal_texture_color(ind,x,y,z,nx,ny,nz,xtex,ytex,col,alpha)
- Add vertex (x,y,z) to the model, with normal vector (nx,ny,nz), with texture
- and color values.
- d3d_model_primitive_end(ind)
- End the description of the primitive in the model.
-
-
-
-Besides primitives you can also add basic shapes to the models. Again the functions look almost
-the same but with a model index and without texture information:
-
-
-
- d3d_model_block(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat)
- Adds a block shape to the model.
- d3d_model_cylinder(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat,closed,steps)
- Adds a cylinder shape to the model.
- d3d_model_cone(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat,closed,steps)
- Adds a cone shape to the model.
- d3d_model_ellipsoid(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat,steps)
- Adds a ellipsoid shape to the model.
- d3d_model_wall(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat)
- Adds a wall shape to the model.
- d3d_model_floor(ind,x1,y1,z1,x2,y2,z2,hrepeat,vrepeat)
- Adds a floor shape to the model.
-
-
-
-Using models can considerable speed up the graphics in your 3D games and you should use
-them whenever you can.

-The 3D functions in Game Maker can be used to make some nice 3D games.
-However, they are limited in functionality and still leave quite a lot of work to you.
-Don't expect that you can make your own Quake with it. Game Maker is and remains primarily
-a package for making 2-dimensional games.

Sounds and music
-
-Most games have certain sound effects and some background music. Many useful
-sound effects can be found on the Game Maker website. Many more can be
-found on other places on the web.
-
-
-To create a sound resource in your game, use the item Create Sound in
-the Resources menu or use the corresponding button on the toolbar.
-The following form will pop up.
-
-
-
-
-
-To load a sound, press the button labeled Load Sound.
-A file selector dialog pops up in which you can select the sound file.
-There are two types of sound files, wave files and midi files.
-Wave files are used for short sound effects. They use a lot of memory
-but play instantaneously. Use these for all the sound effects in your game.
-Midi files describe music in a different way. As a result they use a lot
-less memory, but they are limited to instrumental background music.
-Also, default only one midi sound can play at any time.
-
-
-Once you load a music file you can listen
-to the sound using the play button. There is also a button Save Sound
-to save the current sound to a file. This button is not really required
-but you might need it if you lost the original sound.

Backgrounds
-
-The third type of basic resource is backgrounds. Backgrounds are usually large images
-that are used as backgrounds (or foregrounds) for the rooms in which the game takes place.
-Often background images are made in such a way that they can tile an area without visual
-cracks. In this way you can fill the background with some pattern. A number of such
-useful backgrounds are bundled with Game Maker. Others can be found on the
-Game Maker website. Many more can be found at other places on the web.
-
-
-To create a background resource in your game, use the item Create Background
-in the Resources menu or use the corresponding button on the toolbar.
-The following form will pop up.
-
-
-
-
-
-At the top-left you can indicate the name of the background.
-You are strongly recommended to give every background (and other resource)
-a descriptive name.
-
-
-Press the button Load Background to load a background image. A file
-selector is shown in which you can select the background you want. At the
-right of the dialog you can indicate whether you want to make the
-background opaque (that is, remove any transparent parts), whether
-to remove the background, making it transparent (default not), and whether to smooth the
-edges of the background, which can improve its appearance when it is partially transparent.
-When you are happy with the result press Open to load the background.
-Game Maker supports many image formats. Background images cannot
-be animated!
-
-
-You can change the background or create a new one using the button
-Edit Background. This will open an extensive image editor. For
-information on how to use the image editor see the section on
-Editing images.
-
-
-Be careful with large backgrounds. Some old graphics cards cannot handle images that are larger
-than the screen. So preferably keep your background images smaller than 1024x1024.

-
Keep backup copies of files.
- If checked the program saves a backup copy of your game with
- the extension gb0-gb9. You can open these games in Game Maker.
- You are strongly advised to use at least one backup copy for your work!
-
Maximum number of backups.
- Here you can indicate how many (1-9) different backup copies
- should be remembered by the program.
-
Show progress while loading and saving files.
- If checked, when load or save a file a progress indicator is shown.
-
At startup check for, and remove old temporary files.
- Game Maker and games created with it, create temporary files.
- Normally these are automatically removed but sometimes, for example
- when games crash, they are left behind. If this option is checked,
- Game Maker checks whether such files exist and removes them at startup.
-
Don't show the website in the main window.
- When checked the image and link to the website on the main window are not shown.
-
Hide the designer and wait while the game is running.
- When checked the game making program is hidden while you are testing a game.
-
Run games in secure mode.
- If checked, any game created with Game Maker that runs on your
- machine will not be allowed to execute external programs or change
- or delete files at a place different from the game location.
- (This is a safeguard against Trojan horses although success is not
- guaranteed.) Checking this means that games that utilizes external
- files etc. won't be running correctly.
- The setting only works while Game Maker is running.
- So if you run the game independently of Game Maker, for
- example as an executable stand-alone, it is NOT
- run in secure mode.
-
Show news on startup. Whether to show the Game Maker news
- once a day when the program is started. (Cannot be changed in the Lite Edition.)

-
-
Scripts and code tab
-
-
-
-
-
-
-These settings relate to the built-in script and code editor.
-Most of these settings are explained in detail in the page on Scripts.
-Here we just give a short overview:
-
-
-
Group undo operations When grouped multiple actions (like typing a whole line) becomes
- one operation for undo.
-
Number of undo You can change this number but in general this should be fine.
-
Automatic indentation When set Enter and Backspace keys cleverly deal with indents.
-
Indent amount How much to indent with each tab.
-
Smart tabs When set tabs go to the position below the first non-empty space in the previous line.
-
Allow cursor beyond end of line When checked you can place the cursor at any position in the editor screen,
- also beyond the end of line. If unchecked this is not possible. This also changes the behavior
- of the left and right arrow keys.
-
Show auto-completion options When set help is given on which functions and variables start with the
- letters you are typing.
-
Dealy (msec) The delay in milliseconds before the help is shown. Set e.g. to 0 for immediate.
-
Show function argument help When set, when typing function arguments, in the statusbar help about
- this is provided.
-
Show find string When set, whenever typing in a find string, all locations are shown in the code.
-
Show line numbers Whether the editor should display the line numbers.
-
Show matching brackets Whether the editor should indicate matching open en close brackets.
-
Show code snippets with F2 When set, pressing F2 will bring up a number of useful code snippets.
-
Check code while typing When set the code is constantly checked and errors reported.
-
Use color coding Whether to use color coding in the editor.
-
Colors Here you can set the colors used for color coding. You can also reset the default colors.
-
Font Here you can select the font for the editor. Note that only fixed pitch fonts are shown. Also
- note that only the font and the size are used.
-
-
-
Editors
-
-
-
-
-
-
-Here you can choose whether to use the built-in code editor (highly recommended) or
-an external editor. In the case of an external editor, the script text is saved as
-a .txt file and the editor is called with this file as an argument. After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
-Also you can choose whether to use the built-in image editor (highly recommended) or
-an external editor. In the case of an external editor, the image is saved as
-a .png file and the editor is called with this file as an argument. After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
-Finally you can indicate the different external editors for the sound files you want to use.
-Game Maker does not contain internal sound editors. There are three possible editors
-handling .wav, .mid and .mp3 files. In the case of an external editor, the sound is saved as
-a .wav, .mid, or .mp3 file and the corresponding editor is called with this file as an argument.
-After editing it
-you should save the file and close the editor such that Game Maker can read the
-file back in.
-
-
-
Other Settings
-
-
-It is also possible to change the location of the temp files that Game Maker creates
-to e.g. store the game that is tested. This location cannot be changed from the Preferences but
-is changes by creating a file tempdir.txt in the folder where Game Maker is located.
-In this file there should be one line containing the location of the folder in which the temp files
-are creates, for example C:\GMTEMP. Note that the name must include the complete path
-and should not end with a backslash. Each time Game Maker is run a unique temporary folder is
-created within this location. So things will work out fine, even when multiple instances of Game Maker
-use the same location. (Note that the games themselves also create a temp folder for their files. Again,
-this can be changed by creating a file tempdir.txt and placing it in the folder where the game
-executable is located.)
-
-
-Secondly, it is possible to change the image Game Maker is using for the background of its main form.
-To this end place an image file back.bmp in the folder where Game Maker is located.

Deactivating instances
-
-Please be aware that deactivating and activating instances can sometimes lead to
-unexpected problems. So you are strongly advised not to use this feature except for
-very simple situation. It is mainly left in for backwards compatibility.
-
-
-When you create large room, for example in platform games, with a small view,
-many instances lie outside the view. Such instances though are still active
-and will execute their events. Also when performing collision checks
-these instances are taken into account. This can cost a lot of time, which
-is often not necessary. (For example, often it is not important whether
-instances outside the view move.) To solve this problem Game Maker
-contains some functions to deactivate and activate instances. Before using
-them you must though clearly understand how they work.
-
-
-When you deactivate instances they are in some sense removed from the game.
-They are not visible anymore nor are any events executed for them. So for
-all actions and functions they don't exist anymore. This saves a lot of time
-but you have to be careful. For example, when you delete all instances of a
-particular type, deactivated instances are not deleted (because they don't
-exist). So don't think that a key a player picks up can unlock a deactivated door.
-Also persistent deactivated instances are not moved over to the next room (even
-though they are persistent). Also make sure that after you deactivate an instance that
-you no longer execute code for it. This can in particular happen when an instance
-deactivates itself. In general you better never have an instance deactivate itself.
-
-
-The most crucial mistake you can make is to deactivate the instance that is
-responsible for the activation. To avoid this some of the routines below allow
-you to insist that the calling instance should not be deactivated itself.
-
-
-Here are the available routines:
-
-
-
- instance_deactivate_all(notme)
- Deactivates all instances in the room. If notme is true the calling instance
- is not deactivated (which is normally what you want).
- instance_deactivate_object(obj)
- Deactivates all instances in the room of the given object. You can also use all
- to indicate that all instances must be deactivated or the id of an instance to
- deactivate an individual instance.
- instance_deactivate_region(left,top,width,height,inside,notme)
- Deactivates all instances in the indicated region (that is, those whose
- bounding box lies partially inside the region). If inside is false the
- instances completely outside the region are deactivated. If notme is
- true the calling instance is not deactivated (which is normally what you want).
- instance_activate_all()
- Activates all instances in the room.
- instance_activate_object(obj)
- Activates all instances in the room of the given object. You can also
- use all to indicate that all instances must be activated or the id of
- an instance to activate an individual instance.
- instance_activate_region(left,top,width,height,inside)
- Activates all instances in the indicated region. If inside is false the
- instances completely outside the region are activated.
-
-
-
-For example, to deactivate all instances outside the view and activate the ones
-inside the view, you could place the following code in the step event of the moving
-character:
-
-
-In practice you might want to use a region slightly larger than the view.

-This section deals with how to turn your project into a finished
-game. It describes how to add help information to your game, how
-to set the various options for your game and how to create stand-alone
-games that you can distribute to others and can be run without the
-need for Game Maker.
-
-
-Game Maker contains a built-in programming language.
-This programming language gives you much more flexibility
-and control than the standard actions. This language we
-will refer to as GML (the Game Maker Language).
-In this section we describe the language GML and we give
-an overview of all the (close to 1000) functions and
-variables available to control all aspects of your game.

What is New
-
-
-Version 8.0 of Game Maker has a large number of improvements over version 7.0.
-Below the most important changes are described.
-
-
-
Incompatibilities
-
-
-Text splash screens can no longer show images. However, web splash screens have been added that can
-show full html documents with images, etc.
-
-
-A number of changes have been made to the functions related to sprite and background resources. This
-is due to the fact that Game Maker uses a completely new mechanism for these resources. If your game
-uses a lot of calls to functions that load or save image resources on the fly you are strongly recommended
-to keep using the old version 7.0 for that game.
-
-
-If you use extension packages you will have to reinstall them.
-
-
-
-Some changes have been made to the timeline mechanism that can lead to incompatibilities. In particular, assigning a
-timeline and starting it are now two separate things.
-
-
-
-An important bug has been solved in which collision events where executed twice if two
-objects have collision events with each other. Some games however might have relied on this bug
-and, hence, might no longer function correctly.
-
-
-
News
-
-
-Game Maker now default shows a News page when it is started. Here new versions will be announced,
-new resources will be indicated, there
-is information about competition, and game design tips and tricks. News is shown only once a day. In the Pro
-Edition this can be switched off. You can always access the news through the Help menu and you are encouraged
-to regularly check the news for important information about Game Maker.
-
-
-
Tutorial
-
-
-Game Maker now has a standard built-in tutorial for beginners. It is shown in a panel at the right of the
-screen. Experienced users can indicate that they do not want to see the tutorial anymore. To accommodate for the
-tutorial panel, Game Maker is now default started in full screen mode. It does however remember its settings
-so changing it once to windowed mode will from that moment on start it in that mode.
-
-
-
-
Alpha-blended backgrounds and sprites
-
-
-The new version Game Maker uses backgrounds and sprites with alpha (transparency) channels. This makes it
-possible to create and use much nicer sprites. PNG files with such information are now correctly loaded. The sprite
-and image editor have been completely rewritten, including many new drawing options and effects. A new
-sprite file selector was added that shows the animations in the sprites. Also we bundle
-a large number of high-quality sprites with Game Maker that you can use for free in your games.
-
-
-
-
Enhanced collision checking
-
-
-You now have more collision checking options. For example, you can indicate that collisions should be with an
-enclosed disk and you have better control over the bounding box.
-The sub-image of the sprite can have a combined
-mask and you can set the dependence on the alpha transparency value.
-
-
-
-
Splash screens
-
-
-A new function splash_show_web(url,delay) has been added that can be used to show web pages as splash screens.
-You can also use local html pages for this. This allows for a powerful mechanism to e.g. create help pages. A
-close button is added to the splash screens. Also a number of new actions have been added to show the
-different types of splash pages and to change splash settings. (The old Show Video and Webpage actions have
-been removes as the new actions include them. They will though still work in old games.)
-
-
Trigger events
-
-
-A new type of event has been introduced: Trigger events. Trigger events you can specify yourself. You give them
-a name and a condition, written in GML. After this they can be used in all objects, just like other events. With
-this you can easily extend the functionality of Game Maker.
-
-
-
Time lines
-
-
-The timelines have been extended. The property form has additional buttons to e.g. spread out the moments and
-to delete or duplicate ranges of moments. Timelines can now be paused and restarted and they can even be played backwards.
-Also they can now loop automatically.
-
-
-
Importing and exporting resources
-
-
-The possibility to merge games has been replaced by a much more extensive system to import and export resources.
-The user can indicate which resources to export to a file (.gmres). Next they can be imported in a different game.
-In principle only one resource can exist for each name. When there is a name conflict when importing the
-use can specify to keep the original, replace anyway, take the one that is most recently changed, or
-keep both (not recommended). To be able to do the third option, all resources now keep track of when
-they were last changed.
-
-
-
Rewritten script and code editor
-
-
-The built-in script/code editor has been completely rewritten, making it a lot easier to write code.
-For example there is pop-up function name completion, argument help, matching brackets, improved color coding,
-line numbers, on-the-fly error checking, code snippets, and a sophisticated find and replace functionality.
-
-
-
Speed improvements
-
-
-The speed of games that use code has been considerably improved. A speed-up of up to 100% is
-sometimes possible. Also the loading time for games is often considerably improved.
-Also when running a stand-alone game.
-
-
-
-
Other changes
-
-
-There are a number of other changes and additions. Here are some of the important ones.
-
-
-
You can now use high quality icons for your games.
-
Constants can now be defined in their own form (rather than through the Global Game Settings).
- As a result they can remain visible while you are e.g. writing scripts. You can also load and
- save the constants to text files.
-
Also included files are no longer shown in the Global Game Settings but in their own form.
-
Many small visual improvements
-
Added function random_range(x1,x2), irandom(x), and irandom_range(x1,x2). The latter do give
- integer results and can include x or x2.
-
Added functions mouse_wheel_up and mouse_wheel_down.
-
Added a function set_application_title(title) to set the title of the application
- (which is shown in the taskbar).
-
Added function file_text_eoln().
-
Added read-only variabe debug_mode.
-
There is now a game setting to disallow screensavers or powersaving options (sleep, hybernate) while
- the game is running (default disallowed).
-
Added functions disk_size(drive) and disk_free(drive) and a variable gamemaker_version.
-
Runtime error messages better indicate the position of the error
-
You can now change to location of the temporary files, see the page on Preferences.

Solved a bug in ds_grid_add/multiply/set_grid_region.
-
Calls to scripts and extension functions now return a value of 0 when they do
- not assign a return value themselves.
-
Solved a serious bug in which collision events where executed twice if two
- objects have collision events with each other.
-
Solved a bug in draw_text_ext with empty lines (multiple #) and a problem with
- drawing strings that contains CR-LF pairs (when using multiline strings in code).
