script_exists(scr);
| Argument | Description |
|---|---|
| scr | The name of the script that you want to check. |
Returns: Boolean
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 Advanced Use:
Scripts.
script[0] = -1;
script[1] = scr_AI_Left;
script[2] = scr_AI_Right;
var script_num = choose(0, 1, 2);
if script_exists(script[script_num])
{
script_execute(script[script_num]);
}
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.
