Well... I usually have all the actions needed by the entity put into a single script and seperated by states or activation values, but yes... you can have the entity execute a seperate FPI script by using "runfpi=X" where X is the name of the script you want to execute in the scriptbank folder. If the script isn't in the scriptbank folder directly.... like say it's in "scriptbank\myscripts" you'll have to give "runfpi=myscripts\this.fpi"
The one and only,
Those who live in the past, are destined to insanity. Those who live only for the future, will be slaves to their ambitions.
Those who live in the moment... only they, are truly happy.
