I was going through the manual inregards to physics and to tell you the truth, it is all French to me. What I am trying to do is make a ball, that is bouncing in a hollow 3D rectangle, bounce correctly. Any clues or suggestions?

I found the physics articel in AUM 25 a good start. The example is for the com edition as well.

Well, I tried that. Thank you for pointing it out. The problem I am having now is I added some gravity so the ball would come back and not get stuck, but the ball loses momentum because of the gravity. How would I make the ball regain momentum when it hits the paddle? Any ideas.

Add an EVENT_FRICTION and add phent_addcentralforce along the NORMAL vector upon impact.

Should I add this to the paddle that hits the ball or the ball it self? Thanks for responding.

Is it possible to have an object change the gravity when it hits it. Like have gravity be positive and when it his a brick make it negative.

You can change the gravity at any time, but it will affect all entities. To move just a single object use phent_addcentralforce to counter gravity.

The problem I am having now is the movement of the ball. I have the gravity changing when it hits the bricks and paddle, but the walls appear to kill the gravity to a point where the ball will bounce just back and forth in the square it is in.

here is a link to the beginning of the game. It runs and you can see what I meand then check the code if you wish.
