unfortunately, I'm no scripter(or at least I don't have the knowledge behind this script to figure it out), nor did I even create or modify this script. I just know that I ripped it off of some other forum site based on rpg makery stuffs, and now I put it up. I used it myself, I remember getting an error, but it was resolved when I carved out the animated sideview crap. Otherwise it all worked just...swell.
Err, sorry? Did you copy paste the script into your game? Or start your game anew from that? I can never seem to functionalize battle scripts like they claim to work if I copy paste the script in there, something always seems to just go wrong. Perhaps you should consider copy pasting your game into the demo and see if it works out.
