Description

With this function you can check to see if the given particle type indexed exists in the game or not. Note that if the variable being checked is an uninitialised variable (that a particle typewould otherwise have its index assigned to) this will throw an error.

Syntax:

part_type_exists(ind);

Returns:

Boolean

Example:

if !part_type_exists(global.p1)
    {
    global.p1 = part_type_create();
    }

The above code checks to see if the global variable "p1" stores the index of a particle type and if it does not it creates one.
