Pong - Ping pong game 3 CurveBall

This is my Pong Game. If you haven't see the first or second here are the [link] and [link] .

I announce that I will atempt into adding something that wasn't EVER saw in ANY pong game! The CurveBalls! I actualy know how to creat the curve, but detecting it will be hard.
The CurveBall Should (if my plans doesn't change) happen when the ball hit the bar will the bar is moving.

-New-
4 of the 6 objects have been programmed. I need 2 more ideas! If anyone has any feel free to help me

-Also planned-
adding to everything I said on the second picture, I am planning on adding thousand of options (customizable Ai, 2 player, Objects on/off, possibility to play with mouse, adding blocks in the middle (like in Brick Breaker), CurveBall on/off, and much more!!!)

If you give me an idea and I take it, i'll give you credit directly in the game. (this way everybody playing it will see it)
