part_system_automatic_draw(ind, automatic);
| Argument | Description |
|---|---|
| ind | The index of the particle system to change. |
| automatic | Whether automatic drawing is on (true) or not (false). |
Returns: N/A
This function can be used to switch off the drawing of a
particle system so that any updates done to the system (automatic
or otherwise) will not be seen. This is a purely visual option and
when set to false you will not be able to see the
particles as they are not drawn, but they still exists and are
changing position, colour etc... as they would normally. When
automatic drawing is off, you can explicitly order
GameMaker: Studio to draw the current state of the particle
system using the function part_system_drawit, and if
you set this function to true again you can switch
automatic drawing back on.
One thing to note is that if you are using the simple effects
created by the functions effect_create_above
or effect_create_below
then you can use the values of 0 (for below effects) or 1 (for
above effects) as the particle system index and so toggle the
automatic draw for these too (this will also work to toggle drawing
for the D'n'D particle effects).
part_system_automatic_draw(global.Sname, false);
The above code switches off automatic drawing for the particle system indexed in the global variable "Sname".
