The _update function handles user input and updates to your game’s state. For a game that requires mouse input, you’ll need to make a special call to enable it: function _init( ) This function isn’t strictly part of the game loop since it only runs once, on start. Start by setting up any required actions in _init().

This first revision will display a cursor on the screen that moves as you move your mouse. You can see how these work by creating the skeleton of a game. These functions are special because PICO-8 calls them automatically, when necessary. PICO-8 has excellent built-in support for a game loop via its functions _init(), _update(), and _draw(). You may not win, but at least you'll tie.Whichever language you’re using, game development typically centers around a “game loop”. If you always pay attention and look ahead, you'll never lose a game of Tic-Tac-Toe. You are forced to play in a particular square or lose the game. If the computer gets two O s in a row, you have to put your next X in the last empty square in that row, or the computer will win. You also have to watch where the computer puts its O. Where's the best place for your next X ? You look at the empty squares and decide which ones are good choices which ones might let you make three X s in a row. The other part is trying to figure out how to stop the computer from getting three O s in a row.Īfter you put an X in a square, you start looking ahead. Part of your strategy is trying to figure out how to get three X s in a row. Strategy means figuring out what you need to do to win. To beat the computer (or at least tie), you need to make use of a little bit of strategy. If no player has 3 marks in a row, the game ends in a tie.

When all 9 squares are full, the game is over.

The first player to get 3 of her marks in a row (up, down, across, or diagonally) is the winner.

Players take turns putting their marks in empty squares. You are X, your friend (or the computer in this case) is O.The game is played on a grid that's 3 squares by 3 squares.Tic-Tac -Toe (along with a lot of other games) involves looking ahead and trying to figure out what the person playing against you might do next. But if you really wrap your brain around it, you'll discover that Tic-Tac-Toe isn't quite as simple as you think! It's a really simple game, right? That's what most people think. You probably already know how to play Tic-Tac-Toe.
