Path Nodes and Scripting Them

[Skoth]

I did try searching the forums for something along these lines but I wasn't able to locate anything. I should probably also say that I'm under the impression that a path node would be the track along which an entity (presumably an enemy) walks along, right ?

If that is indeed the case, how would one go about scripting the path nodes? I'm sure that's quite a broad question, but say for just scripting an enemy to go from its starting point to one path node.

Thanks all!
