I went ahead and removed it just now. It was in it's own script section, and since it wasn't used by anything it didn't affect anything either way. Have you play tested to see if the battle system is working right? And I also have a suggestion (not sure how hard it is to implement though). What about a sound effect each time one of the pokeballs on the sides lands in the stack (in trainer battles)? I'm pretty sure the official games do that.
I finally got around to updating the battle script for you and adding the mouse script (even though it's not actually used at present. it was for that sign thing). I play tested it and it looks like everything checks out (and the game looks awesome so far btw). If I left anything out, let me know.
Are you meaning the stuff I was working on before that never worked once it was transferred? Well, if you're using a new kit then yeah, just let me know how to use the dropbox and I'll try to move everything to it and see what happens.
