I wrote my own A* implementation based on this tutorial, but for some reason it never finds the end point. Here's my implementation: -(NSMutableArray *)findPathBetweenPoint:(CGPoint)p1 andPoint: ...
I have this problem where I have to find the shortest path in an NxM grid from point A (always top left) to point B (always bottom right) by only moving right or down. Sounds easy, eh? Well here's the ...

Below are the bunch of functions which I wrote to determine paths between give coordinates of a square tile-based game. It permits paths between tiles in 4 directions (i.e. not 8 directions/diagonal ...
I've implemented A* according to the pseudo-code on Wikipedia. I'm going to worry about optimizing it later, but for now, I'd really like to know if the code is correct. typedef std::tuple<int, ...
