Argument Description scr The name of the script that you want to check.
This function will return true or false depending on whether the script with the given index exists. Note, that this is not a string, but rather the asset name which holds the unique index for each script (as it would appear in the IDE). For more information on scripts, see The Script Editor.
script = -1;
script = scr_AI_Left;
script = scr_AI_Right;
var script_num = choose(0, 1, 2);
The above example adds two scripts and a value into an array, then proceeds to get a random number and use that to choose a script to run, unless the real is chosen in which case nothing will happen.
