I need help to get started with making a TicTacToe game..

I only have codes that make each cmdbuttons to change its text to X when a user clicks at them.

I can't figure out how to make the computer decide which box it would want to pick.

Even if i wanted the comp to randomize and pick any buttons that are not yet chosen, how would i do that? I don't know if I can randomize buttons.. If you know what I mean.. Like..

VB Code:

Dim RndPick As Integer
Randomize
RndPick = Rnd() * 9 + 1
If RndPick = 1 Then Button1.Text = "O"

That's how I've thought of the comp choosing a button, but when it comes to the part where the comp has to block a 3 straight Xs...

Can someone get me started with this?

Thanks in advance.:)

All I can think of as of now is to try every possibilities... Like, make a function that determines which box the CPU is going to choose, and see if ONLY button1 is checked, then choose a couple of possible winning picks.

But that would make the code to be really long. There has to be a shorter way... I think..

Any help?

This might give you some ideas:-

It uses 2-dimensional arrays to track the positions of tic/tacs. There are other ways you could do it. Looking at the the above link you will see the 8 possible lines that create a win. You could track how close to complete a line gets after each move.

Hey, thanks!
It'll help me a lot!

However... :)
I was thinking about playing against the comp...

Here is a link of a source code of a tic tac toe game with AI: http://freevbcode.com/code/TTT_AI.zip.

I can't figure it out... Especially the part about patterns in AI module...

Here's another example, which, of course, I couldn't understand :): http://freevbcode.com/code/nghtcros.zip.
