   Hey all,
   So i finally got my game logic set up and its running a lot smoother. Earlier I asked about adding chipmunk bodies inside the sprite subclass and that works perfectly the problem im having now is that when two of the bodies collide it crashes. it wasnt doing this when I had them being made inside my activelayer. now i have a subclass of sprite that makes them and they appear and the bodies that were made together (ex. all of the enemies) will work fine but if there are two bodies made in a different class it crashes.

   any ideas?

   I;m not sure what code you want me to post. So let me know

   Thanks

   You get a crash when they collide? Do you try to remove the objects (bodies, shapes, sprites) during collision callback?
   Please elaborate.

   The only time i remove a shape is after it has been hit 3 times. it crashes on the first hit. and when i do remove the shapes its after the chipmunk step.

   Ok. so it seems like its not a problem of it not working its something else. if in the collision callback i put:
   NSLog(@"hit");
   it works but if i put:
   NSLog(@"%@", a->data);
   it crashes

   when i make the sprites i put this for the data:
   enemyShape->data = [NSString stringWithFormat:@"enemy%i", i + 1];

   is there something wrong with that? because if i do:
   NSLog(@"%@", enemyShape->data);
   right after it it displays enemy1, enemy2 and so on

   Any ideas?
   Thanks

   try adding a retain to the original string, see if that works. Don't forget to dealloc when you removed your shape later.
