Serve issues

[etray]

• Bouncing off a perfectly 90-degree plane will always maintain the same starting angle. This matches how balls bounce in nature, but can be tiresome in pong if the ball is served at a steep angle.
• Maybe the paddle surface could behave like a parabola, bouncing ball in slightly different directions depending where you hit on the paddle.
• Maybe we could limit the randomly-generated serve trajectories to maintain aesthetic angles.
• Maybe rather then random serves, the serve can always come straight at you, and the special parabolic paddle behavior can makes the angles change in a user-controlled way.

Update:

• Narrowed the serve zone to prevent balls from embedding themselves in the wall - also sped-up the physics loop interval, because If moving too fast, it can't keep up, and you end up stuck inside the wall.
• Random serve angle - constrained so that x velocity contributes between 40-100% of of the motion, and you have less vertical bouncing,
• Made 3 zones on the paddle - middle-third doesn't change the bounce angle. The top third and bottom third alter the angle slightly
• It could all use improvement, but it works Ok for the time being.

I have a post it note with some information on this concept. I'll have to upload the details later!
