Actually, I used a proprietary language from GameMaker. Sorry I'm still not understanding your question though. Every object in a level exists and are never deactivated or anything like that. The window just acts as a camera/viewport of the level with a physics object attached. It's similar to a sidescrolling action game.
Ok, I understand. The problem is that you used gamemaker while I use java! Anyway, thanks for the atention!
