24/4/2016 7:43 am by Netopia in Web Development

I'm creating a chess game, I already created the rook's and the bishop's and I'm about to start creating the queen piece.

Im trying to filter the zeroth arguments of the function using the other arguments of the function. The loop and filter functions seem to be working but the problem seems to be that the loop doesn't loop all the way through. I'm not exactly sure what is going on in this case. Here is the code:
