     This is a A* pathfinding example to illustrate how to implement a A* pathfinding algorithm into your program. It's a port from Patrick Lesters example in BlitzBasic to VB.Net. It uses a Binary Heap class I made to sort the score values. It's very rough around the edges and needs alot of work to be anything more than an example. Let me know what you think.

does it recalculate the cell cost if it finds a shorter path to the same cell?
(coz if it doesnt its not a 100% a* , then its a mix of a* and best first)

Yes it recalculates the GCost of it's parent cell if it finds the previous examined cell to be a shorter path. It's a real A* algorithm, uses FCost + GCost (Tile Move Cost) + HCost (Manhatten Heuristic)

It would be cool if you show dynamic calculation and back-tracking.
