Check if a tile is in front of you before moving

[Hblade]

I 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?

If you don't have some data structure like an array holding the tiles, you'd need to use either getactor, CollisionFree, or a colliding actor. If you do have a data structure, you just need to check the position to the left to see if it is empty or not.

If it's not too much trouble, would you mind explaining (or linking to a site that can explain it) a data structure?

First google search for data structure gives the wiki page. http://en.wikipedia.org/wiki/Data_structure
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.
