Physics

[DevulTj]

Couple of physics related problems to note:

• [ ] The paddle has to be in motion, preferrably when flicking it to hit the ball. Otherwise, the ball just goes through the paddle.
• [ ] Should be able to just rest the ball on the paddle. Place a ball on the table, then from under the table, just gently bring it up onto the ball.
• [x] The ball shouldn't bounce forever.

Can solve a lot of this by making the paddle hitting balls entirely clientside authoritative within FrameSimulate, we'll still wanna do sweep traces - the key part is doing it before the ball moves. Actually we should be simulating the ball physics in FrameSimulate as well.

This will probably feel odd unless we:

• [x] Have the ball physics simulated clientside as well. The physics are deterministic so it should be simple enough, unless the engine fights us.
• [ ] Lag compensate serverside for the other player to correct the ball for the other player.
