My project with 6-plus hours worth of programing now crashes plz help

[Slayer2520]

So I've been making a knock version of final fantasy for a programming class. I've created a randomizer so that it runs battle scenes at random and it crashes as the enemy HP number variables drop to or below 0 and I have a function to end the battle scene.

Error during simulation.




Alice version: 2.2 8/1/2009

Ugh, that's an ugly one.

Post your world and I'll see if I can fix it for you.

[Slayer2520]

Please and thank you. I think it's a little late to be helped on my project but I would like to learn what it is that I am doing wrong. Thank you.

The only error I'm getting from your world is the error I always get when an Alice world uses an event to interrupt an animation (which I'm told only happens to me and a few others). The sound plays fine, and I'm betting that if I fixed the glitch, the world would play fine too.

I know, ive lost 16 hours of work but its ok now, ive worked on a better version of it. Im sorry btu all i can say is, go to and older back up version of it and see if it works, you can not fix it
