cocos2d - Path Finding and Tile Maps- Sample App

http://www.cocos2d-iphone.org/forum/topic/7817

I've been playing around with path finding and tilemaps along with the latest release of cocos2d-iPhone - and I posted a sample app in hopes that it saves someone else some time - or if anyone has comments to optimize/improve this code (I'm sure that won't be difficult as I wasn't shooting for optimization, just trying to learn).

I started with two great tutorials:

Ray Wenderlich's cocos2d-iphone tile map tutorial:

and BravoBug's A-Star sample program:

My sample app loads a tile map that contains a start point, an end point, and walls, and detects (and graphically displays) a path between the start and end points. You can select whether or not you want to allow diagonal movements. Anyway, here's the link. I hope someone finds it useful:
