Not quite: bouncing off flat (right angled) surfaces is easy (eg: hVelocity
* - 1); however when the ball hits a sloped wall the calculation is not so
simple.
* I use the horizontal & vertical velocities (vectors) to move the round
ball;
* I have the angle of the wall (rise / run)
* Collisions are perfectly inelastic;
