*Note, I just edited Steve LoBasso's program. New features include exploding rounds, constant gravity, and cooler sound effects.* *Also note- shells only explode when the game is downloaded.* Left and right arrow keys control the angle. Up and down arrow keys control the power. Space to shoot. Wind is randomly chosen when a new terrain is drawn. The value of a hit drops after every miss. You can hit your own fort, so be careful. The terrain is drawn using several quadratic bezier curves. The sine and cosine are calculated using a quadratic approximation.
