Game Dev - Storing and Altering Grid Information

I messed around with the code and added the main info I need to manipulate and edit the grid based on the pattern that gets laid on top. It currently automatically applies the pattern instead of requiring a "confirm" button click, but at least the updating of data is sound.

The next hardest part is to place down player tokens, have them roll a die, and then determine the valid moves that piece can make. I'm a bit too tired to think about it right now. I'm assuming it has something to do with an "automated walk feature".
