Need-to-know basis

It's an improvement, but that line is still monstrous! Notice the repeated element square.GetComponent.<Square>().y. Why say it three separate times, when we can say it once and store it in a variable?

We'll probably need to know square.GetComponent.<Square>().x as well to check the columns. So let's just store the first part, square.GetComponent.<Square>(), in a variable as follows:

function CheckForWin(square:GameObject):boolean
{
  var theScript:Square = square.GetComponent.<Square>();

So now the code for checking the square's column becomes:

if(aGrid[0,theScript.y].GetComponent.<Square>().player == currentPlayer && aGrid[1, theScript.y].GetComponent.<Square>().player == currentPlayer && aGrid[2, theScript.y].GetComponent.<Square>().player ...
