Be sure to have "nodes/paths.ipl" file existing, copied from game folder.

make a folder nodes/path.ipl along with server.lua and xml?

[Anonymous]

the nodes folder goes in same folder as server.lua

it just loads the path data

it doesnt put peds on paths

I've just noticed that this code depends on a string explode() function, I've added that to the first post in this thread.
