![]() Grids contain additional structure that graph search algorithms don’t take advantage of.įor example, if you move east one space on the grid, it’s likely that moving east again is going to be a good move. If you can’t use an alternate graph structure for pathfinding, there are optimizations that can be applied to pathfinding running on a grid. There are also some approaches from the game developer community see this paper for descriptions of those techniques (including JPS+). See l1-path-finder for a fast implementation and also more references to papers. There are multiple algorithms in computer science literature that can improve pathfinding for grid maps with grid (“L1”) movement. These two have the same set of waypoints: Note that movement can be on grid even if your map representation is not. Irregular edges can be represented by many small squares. Large open areas can be represented by a few squares. Quad trees use square regions of various sizes to represent the map.An approximate path is found with the coarse level, and then refined with the fine level. ![]()
