Hello,
A friend of mine and I made a bet 2 days ago. He was playing pong and he was bragging about how good is he beating the AI and I told him: "I can make an unbeatable AI for this game with 1 single line of code". His answer: "NO WAY YOU CAN DO THIS" (he never programmed a game in his life). But he don't know that artificial intelligence in games is more artificial and less intelligence because computer controlled players just simulate intelligence. We made the bet and I've won some beer money :d
Here is the 1 line code for the AI:
ai_paddle_y = ball_y;
