Paddle and trajectory

niwuc

In a simple ball and paddle game, is there anyway to keep the ball moving in the same direction (say from left to right) with out having to worry about changing trajectory when you bounce it off of the paddle?

For instance; if the paddle is moving quickly towards the ball and the ball collides while the paddle is moving, the ball will obtain a new trajectory.

Basically I'd like the ball to keep a pretty constant path for each bounce with out worrying about sending in a different direction.

Thanks
