Tic tac toe

Question

I am working on the tic tac toe problem and i need help with the AI part i got it to work for 1v1 but it needs to be 1vAI

I was thinking that easiest was to to program something like "when player clicks this squaure, AI will click anything"

Should I create another temp button then everytime
tempbutton is used make tempbutton2 also move?

Belowe is the code for the clickhandler part

Thanks

private void ClickHandler(object sender, System.EventArgs e)

{

Button tempButton = (Button)sender;

if( this._isGameOver )

{

MessageBox.Show("please start new game!","Game End",MessageBoxButtons.OK);

return; 

}

if( tempButton.Text != "" ) 

{

return;

}

if( _isX ) 

tempButton.Text = "X";

else

tempButton.Text = "O";

_isX = !_isX; 

this._isGameOver = result.CheckWinner(_buttonArray );

}

}

Here's the basic structure you want to aim for:
After the person has taken their go, rotate the go for the next user (like multi-player).
Now write an AI function or class that returns the position in the array where the AI would like to go.
Set the position in the array that the AI() method returns equal to the computers 'go' (O or X).
Perhaps a boolean variable that denotes if your in single play or multiplayer and an if statement for when the button is clicked?

After this if statement which contains the extra code to run for a multi-player game, just rotate the user back to the human players go and let it continue with the code it would run for single player.

That should get you going, if you run into issues post back :)

Ok i added a computer class (at the bottom)

I am not sure how now implment it. I think it the comptuer needs to move everytime after the player moves.

I am really confused because i used buttons to create the tic tac toe problems and the the tuturiol I looked it used an array.

would the comptuer class be implemented in the ClickHandler class?

Thanks

OK,
To use the method you have written at the bottom you must reproduce the text from your buttons into a 2d string array.
make a new method to handle the conversion.
You can use Button.Text to get the text displayed on the button.
You can use String.ToLower to convert the text to lower caase (as that is how your Computer class is written)
Remember that an array will start at 0 rather than 1 like your button naming convention (making [2,2] the equivelent of button 9 for instance).
That should be all you need, Have Fun!
