I have bullet physics set up and working on the iPhone but now I want to implement some sort of path finding with it.

The problem is I have no idea where to start, the level is pretty simple just a lot of pillars that I want the 'bad guys' to navigate around to get to the player character.

Do you have any suggestions or are there any tutorials you recom开发者_运维问答mend for pathfinding using this on the iPhone?
