Glider used a way point based system, which means you could in turn record where you went (For grinding profiles), and then you set glider to a certain yard radius for mobs, nodes, etc, to deviate from those way points. PPather (The nav system that glider used for automatically generating paths) was also used for grinding/questing, however PPather was a resource hog, it took a long time to generate a path to anywhere, and it still got stuck on random objects such as fences, barrels, etc.
The way honorbuddy works, is it creates a navmesh for every piece of land in WoW. It takes seconds to generate a walkable path (And usually much less time then that), and it is pretty much the best out their for wow navigation. Honorybuddy does not use a way point system so you cannot just record and go.
For honorbuddy profiles, you have hotspots, and blackspots, Hotspots are the spots your mobs are at that you want to kill (The general area), or the herbs/mining nodes you want to gather. The bot just needs the hotspots, and it knows you want to go to that area and do your thing, the bot will AUTOMATICALLY generate a path to get there. Blackspots are spots that their may be a navmesh issue, and you might be getting stuck on something, if its consistent you can add a blackspot and honorbuddy will try to stay out of that area (Unless of course it doesn't have a choice).
If you need me to elaborate any further go ahead and let me know.
