[FMX] Circular Pong

Hi. I had an idea for a variation on a game like Pong. I have been trying to program it myself to na avial. Any help would be great.

The game is like any other pong game with one differance. Rather then the paddle only moving left and right, it would move in a circle around the play field and you would not be able to rely on the walls to keep your ball in play.

My problem is that I cant get the ball to bounce off of the paddle at the correct angle. Below is a link of the swf and fla that I have now.

Any help would be great! Thanks
