Known Issues

1. When physics is disabled, and the player's center is inside some solid block, the player couldn't be pushed out when the physics is enabled again. This is the cause of current buggy physics implementation.
2. When raycasting, it is possible that the raycast route squeezes through the interval of two diagonally adjacent solid tiles. So that you will see the AI tank stupidly stuck on the diagonally adjacent tiles.
3. It is possible that you will be pushed into solid tiles's adjacent intervals, thus going through the wall.
4. Sometimes you can see tile boundaries in view.
