<h3>Paths</h3>
|

|
|
|

|
|
The following functions will give you information about a path:
|
||
|
|
|
||
|
|
<p>
|
||
|
|
<blockquote>
|
||
|
|
<tt><b>path_exists(ind)</b></tt>
|
||
|
|
Returns whether a path with the given index exists.<br>
|
||
|
|
<tt><b>path_get_name(ind)</b></tt>
|
||
|
|
Returns the name of the path with the given index.<br>
|
||
|
|
<tt><b>path_get_length(ind)</b></tt>
|
||
|
|
Returns the length of the path with the given index.<br>
|
||
|
|
<tt><b>path_get_kind(ind)</b></tt>
|
||
|
|
Returns the kind of connections of the path with the given index (0=straight, 1=smooth).<br>
|
||
|
|
<tt><b>path_get_closed(ind)</b></tt>
|
||
|
|
Returns whether the path is closed or not.<br>
|
||
|
|
<tt><b>path_get_precision(ind)</b></tt>
|
||
|
|
Returns the precision used for creating smoothed paths.<br>
|
||
|
|
<tt><b>path_get_number(ind)</b></tt>
|
||
|
|
Returns the number of defining points for the path.<br>
|
||
|
|
<tt><b>path_get_point_x(ind,n)</b></tt>
|
||
|
|
Returns the x-coordinate of the n'th defining point for
|
||
|
|
the path. 0 is the first point.<br>
|
||
|
|
<tt><b>path_get_point_y(ind,n)</b></tt>
|
||
|
|
Returns the y-coordinate of the n'th defining point for
|
||
|
|
the path. 0 is the first point.<br>
|
||
|
|
<tt><b>path_get_point_speed(ind,n)</b></tt>
|
||
|
|
Returns the speed factor at the n'th defining point
|
||
|
|
for the path. 0 is the first point.<br>
|
||
|
|
<tt><b>path_get_x(ind,pos)</b></tt>
|
||
|
|
Returns the x-coordinate at position pos for the path. pos
|
||
|
|
must lie between 0 and 1.<br>
|
||
|
|
<tt><b>path_get_y(ind,pos)</b></tt>
|
||
|
|
Returns the y-coordinate at position pos for the path. pos
|
||
|
|
must lie between 0 and 1.<br>
|
||
|
|
<tt><b>path_get_speed(ind,pos)</b></tt>
|
||
|
|
Returns the speed factor at position pos for the path.
|
||
|
|
pos must lie between 0 and 1.<br>
