I need the ball to bounce off only when it hits the paddle, so not as it is doing now - bouncing off when it reaches the y - axis of the paddle, no matter whether the paddle is there not.

Remove line 71 to 73?

When your paddles are on the left and right side

you need to check the y of the ball against y top and bottom of the paddle as I have shown
