Preventing scripts from repeating

[Kyle]

AddEntityCollideCallback("Player", "ScriptArea_1", "Func01", true, 1);

The bolded text above with it saying "true" means that it can only happen once. When it is "false", then it can happen as many times as you want.

If you want it to happen 2 times, for example, then you use a local variable integer to increase the value when it runs the first time and second time, and if it equals 3, then it breaks out of the function before running it for a 3rd time.
