<h3>Destroyers</h3>
|
|
|
|
Destroyers destroy particles when they appear in their region.
|
|
A particle system can have an arbitrary number of destroyers.
|
|
A destroyer has the following properties:
|
|
|
|
<ul>
|
|
<li><tt><b>xmin, xmax, ymin, ymax</b></tt>
|
|
indicates the extent of the region in which the particles are destroyed.</li>
|
|
<li><tt><b>shape</b></tt>
|
|
indicates the shape of the region. It can have the following values:</li>
|
|
<ul>
|
|
<li><tt>ps_shape_rectangle</tt></li>
|
|
<li><tt>ps_shape_ellipse</tt></li>
|
|
<li><tt>ps_shape_diamond</tt></li>
|
|
</ul>
|
|
</ul>
|
|
|
|
<p>
|
|
The following functions are available to set the properties of the destroyers.
|
|
Note that each of them gets the index of the particle system to which it belongs
|
|
as a first argument.
|
|
|
|
<p>
|
|
<blockquote>
|
|
<tt><b>part_destroyer_create(ps)</b></tt>
|
|
Creates a new destroyer in the given particle system. It returns the index of the destroyer.
|
|
This index must be used in all calls below to set the properties of the destroyer.<br>
|
|
<tt><b>part_destroyer_destroy(ps,ind)</b></tt>
|
|
Destroys destroyer ind in the particle system.
|
|
Call this if you don't need it anymore to save space.<br>
|
|
<tt><b>part_destroyer_destroy_all(ps)</b></tt>
|
|
Destroys all destroyers in the particle system that have been created.<br>
|
|
<tt><b>part_destroyer_exists(ps,ind)</b></tt>
|
|
Returns whether the indicated destroyer exists in the particle system.<br>
|
|
<tt><b>part_destroyer_clear(ps,ind)</b></tt>
|
|
Clears the destroyer ind to its default settings.<br>
|
|
<tt><b>part_destroyer_region(ps,ind,xmin,xmax,ymin,ymax,shape)</b></tt>
|
|
Sets the region for the destroyer.<br>
