For some reason the shots sometimes gets stuck. My first AI project. The blue tank wanders the stage and fires at the red tank (you) if it is in sight. Arrow keys to move, P and I turn the turret, O fires. Spacebar changes arena. The top slider changes the AI difficulty (firing rate, far left is slowest, right is fastest) and press 1 on the keyboard lets you see the collison sensors and the line of sight detector.
