Looking for an add-on described in the thread

For nearly a year, I’ve been looking for an add-on that includes simple NPC scripting such as being able to make a NPC walk to designated points on a map, either by patrolling by itself, or by walking to points designated by the player, similar to setting a NPC line when making a map for GeneRally.

I think you’re looking for NPC Commands.

can you post a link to it?
