Make your own tic tac toe ai game3/16/2024 ![]() Keep your eyes open for those winning spots so you can block them before they get three in a row. Most players go for the middle space whenever they can, but don't ignore the corners! You can use the corners to set up multiple winning moves at once, leaving your opponent no way to block your win. TIC TAC TOE TIPS & TRICKS Control the corners If things are still too easy, take it up a notch by switching to hard mode! You can play against a computer, or with a friend on the same computer. Try your skills getting four in a row on the 5x5 grid for an extra challenge. Your goal is to get three in a row before your opponent does. On your turn, click anywhere on the grid to place an X in that square. The 10 however enforces that we give a much higher weight to winning than to blocking (a mistake I initially made the first time round).You are X’s and your opponent is O’s. What the 5 does is give a higher weight to a move that will stop the opponent from winning, as, just like before, we use the same code for the current player and the opponent, since, the higher the weight for the opponents next move, the more you want to block that move. I’ve chosen to add 10 for a win for the current player, and a 5 for the opponent. A move that actually gives us a win gets a higher value. A move that gets us a future winner adds 1 to the element. To do this we create yet another array of weight values, where we test each of the winners against each possible move and add a weight value to that element. Then you calculate weight values against this subset of winner combinations to see which is the best move. The moment you play a location, you can eliminate any of the winners that don’t apply, so you only have to deal with a smaller set of possible plays. The first thing it does is figure out, given the current play, which subset of the winners array applies. The one I chose calculates weights on a move. ![]() ![]() You can take various shortcuts to making an automated player. There are many ways of dealing with tic-tac-toe, mainly because it is so simple and only has 8 combinations that can actually win. It is not the typical minimax algorithm generally chosen. I won’t go into the details of making a plugin, this is covered well in the SDK documentation, so I’ll skip to the runtime functions. ![]()
