I am looking to use pathfinding in our Game called Storm (you can see it at http://www.tashco.com/storm.html All the units, buildings and trees will be positioned on the map given an x,y vector position and not a tile position. Does anybody have any ideas on have to use A* for this problem because most people tent to use it for grids or hex maps. Maybe there is a better algorithm that A* under the circumstances?
