You could make an unbeatable AI that checks moves ahead. Like a bunch of if values:
code:

if bottom_left_square="x" and middle_square="x" then
Draw.Oval(top_right_corner_x,top_right_corner_y,5,5,2)
elsif bottom_left_square="x" and bottom_middle_square="x" then
Draw.Oval(bottom_right_corner_x,top_right_corner_y,5,5,2)
else
%Other things to check all spaces
end if

This of course isnt completely unbeatable, but you can make it unbeatable if you know a lot of tic tac toe combo moves, lik hitting a bunch of certain ones, so you automatically will get a line if you pick 1 of 2 squares to complete a line. Thats one way you could make AI in tic tac toe.

the best AI is to make completely random moves Laughing

otherwise the simpliest AI would be:

DEFEND - block if user has two in a row
ATTACK - move so that AI has 2/3 in a row
RANDOM - if you're not defending or attacking

Bugz made his turing 4x4x4 tictactoe unbeatable AI and coded it in c++ and exported to VB so it has the graphics...Im sure if you ask nicely enough, he would give you the code...........................or maybe not.

Well, either way, I gotta start from scratch!! Boohoo. Oh well. I'll suck it up. Anyone got any tips on making it so that a function says that places are taken?? If not its ok!

look at my tic tac toe in source code... its not AI, but it shows how i made it so you can only click on sq's with nothing in em

just search for "tic tac toe" and "recneps" as the post author in [turing source code] or [turing submissions]... depending on where it was posted and I'm sure you'll find it

See the thing is, a) it wont load for me until I go to close it. And b) it refuses to have the 'x' show up. Can anyone help??

If this same problem has been posted, sorry,m I looked, but mustve missed, if its been asked. If it has, give me the link and I'll go there. Thx!

and if you can't use View.Update, take out the View.Set ("offscreenonly")

that oughta do it
