Nice moves
It seems simple enough to create an int
variable to keep track of the number of moves that have been made, which we'll increment every time a player places a piece. If we're up to the ninth move with no winner, that means all of the squares have been filled and we've reached a stalemate.
At the top of the script, declare a moves
variable:
var gameIsOver:boolean;
var moves:int;
Just above the Instantiate
command in the ClickSquare
function, increment moves
:
moves ++;
Instantiate(piece, square.transform.position, Quaternion.identity);
Tack on an else
to the
CheckForWin
condition check that ends the game if we've reached 9 moves with no winner:
if(CheckForWin(square))
{
gameIsOver = true;
ShowWinnerPrompt();
return;
} else if(moves >= 9) ...
