Node Graphs

I want to get some Grunts patrol down a hall way. I place 4 info_nodes and save map and compile and then the grunts just stand there. How do I get nodes to work?

Info_nods just tell where the idiot AI can and cant go.

If you want your grunts to do a patrol. Make them follow a series of path_corners (or path_ something?)

Its almost identical to making a train or an elevator. You can see my tut about elevs if you want: http://www.snarkpit.com/editing.php?page=tutorials&game=HL&id=28

You can make the AI ignore the player and keep walking even though they see or hear you or the grunts can stop their patrol once they see or hear you.

For that, you dont need info_nodes as far as I know.

Just keep in mind the AI wont walk through narrow hallways or doorways for some reason.

Ah Thank You :heee:

Mark WCs answr correct then.

As a follow up:

info_nodes are there to let the AI know how to navigate the map. Most of the time, monsters won't use them unless something stimulates them (i.e. rival monsters, a yummy dead body to eat, hearing the player, etc.) But with good info_node placement, I've had monsters outsmart me all the time and surround me. They turn into minature-Einsteins.
