I have created 3 cubes that bounce up and down using an if statement that reverses the direction of the cube once it has moved a number of units. I am attempting to speedup or slowdown the speed the cubes bounce by pressing one of 3 keys. When I press one of the keys the speed of the cube changes but does not reverse direction essentially the cube "runs away". Can someone point out what I am doing wrong?
