Update: AI is now 4% smarter than it was an hour ago. :3 Another UPDATE: Now 1% smarter! (I wasn't sure if it would help, so I put to AIs against each other. One was consistently losing. So I changed the losing one and it started consistently winning, so then I updated this. :D)
This AI uses the extreme predictability of the ball bounces to calculate the exact position that the ball will be in when it reaches the paddle. This AI is not possible to beat unless the paddle restrictions are too slow so that it is impossible for the AI to win. But I did my best to account for this. The AI is now as smart as an AI can possibly be.
