this is a zero grav physics engine. it y-bounces on red and x-bounces on black press space to enter custom x and y velocities
completely my own. i will soon make one with gravity. the reason i did not use the bounce on edge block is so that you can add obstacles. i may do it differently so that the ball actually has 3 parts, the core, the right/left sides, and the top/bottom. feel free to use this physics engine as long as you mention that it is from me.
