In my game when 2 objects of the same type collide, they combine to former a different object. The only thing is, I'm not sure how to take account of two instances of the same object and have it result in only one instance of the event.
My dirty solution was to have them both create the object and have the system delete a random instance of it. It seems to work perfectly, but I know it'll cause problems at some point.
Any ideas?
Thank you!
