A* pathfinding on a TMX tilemap
If you've skipped ahead to Chapter 8, Tips, Tools, and Ports, you'll see a recipe showing how to use the Tiled application with the TMX tilemap toolset. In this recipe, we create a 2.5D adventure game. To see our grid based pathfinding technique in action, we overload the Chapter 8, Tips, Tools, and Ports recipe entitled Creating levels using Tiled.
