hello all, ive been trying to get the correct collisions for what i need to work. I have a pusher working but i dont want or need a pusher. All i want is a print statement during every collision describing what object collided with what. heres the pusher code.

run()ive tried collisionhandlerqueue() and event() with no success. could anyone poine me in the right direction?
