A couple of questions:
- What exactly is the role of the node in this scenario? Is it one walkable position of an area you feed to the pathfinder? Or do you feed all walkable positions to the pathfinder (this seems expensive though)?
- To generate the graph, do you walk the surface and collect map data or do you just use a cache from the map and load all data at once?
- Could you explain the word "web" ? What exactly is interlinked? The nodes? If so, why would you need a pathfinder if a relation is pre-established?
I have a couple more, if you don't mind, but perhaps the answers to the one above will also answer those :p
