Tic Tac Toe at the speed of light
Whoa... okay. The computer player plays a piece, but it does so instantly after the human clicks to place a piece. This is what happens when you play a game against a superior intellect!
To dull the game down to human-comprehensible speed, let's build in a brief pause before the computer makes a move just before the function call in the ClickSquare function.
yield WaitForSeconds(2);
ComputerTakeATurn();
Try the game again. There is now a nice 2-second pause before the computer makes a move, providing the illusion that the computer is "thinking" (when really, it's just randomly throwing darts at the wall). This Artificial Intelligence stuff is looking more and more like a magic trick, isn't it?
