Yeah, I have probably 100+ NPCs running this in the new Hills of Shade zone I am working on currently, and I see no CPU utilization increase when they are active. My CPU stays around 2-3%, so it seems like it could be used pretty freely without much concern.
It might be nice to add something that does this into the source to be set similar to how roam boxes are, so you don't need to add anything to the script. I might try to add something like that in at some point if someone doesn't do it before then.
Anyone with SoF can check this script out in action by starting a char on Storm Haven and going to Temple of Marr, and then using the portal there (walk onto the pad labeled "Hills of Shade Portal"). The zone is under development now, but I am leaving access to it up while it is being developed. There is some actual pathing mobs in the zone, but almost everything other than the Mushroom section of the zone is currently using this plugin to handle pathing. I am pretty impressed with how good it works so far. Instead of having to manually create random grids or roamboxes for a hundred or so spawn points, I was able to add this plugin to them and turn hours of work into a few minutes (not counting the time it took to write this plugin and the new quest Objects, of course!)
