my problem is that each tile created won't add to the arraylist.

here is the error output:

I know it's probably a very silly problem but I just can't find it!

That's way too much code to wade through. The problem is that you're trying to access an index that is larger than the ArrayList's size. You can't access index 1 unless you have two items in your ArrayList (index 0 and index 1).
