Modify the provided Tank code to keep the tanks from moving off the screen.

The tank should have an inelastic collision with the wall.

The wall should only restrict motion in the direction perpendicular to itself, but motion parallel to itself is unrestricted and without friction so that that tanks can slide along the wall.

If the tank runs into the wall perpendicularly, then it should stop completely, but should move again when the angle changes.

If the tank hits at an angle, then it should slide along the wall, but won't ever move through the wall.

All tanks should be impacted by the code
