Yes, I should have mentioned...I did set up the door as an active rigid body. Also, the ball is as well. The ball already spins in a bowl and lands in a tube which shoots it out to hit the top of the door, but the door I created and assigned a "active rigid body" acts as if it is transparent because the ball goes right through it. I also have assigned gravity to ball and the door; the door simply stands on it's own.

Any ideas?
Thanks so much for your help I really appreciate it!:bow:
