Check if a tile is in front of you before moving
Posted: Tue May 21, 2013 2:23 amI have a bootleg way for this rambled up in my head, untested though. But what would be a nice efficient way to tell if there's a tile ahead of you before moving?

All you really need is the first sentence from that link. A shorter way of saying the same thing, it is a structure that holds data. Therefore an array is a data structure.
