how can I do to make what is described here but for a Patrol? Like a guard patrolling around a city?
It's easy to setup ... but not easy to get the "guard" to actually and reliably ride horse while on patrol
http://www.creationkit.com/Patrol_%28Procedure%29
So just setup a basic, normal patrol ... and make sure "Use Horse If Possible" is checked
Then:
- IF the NPC has access to a horse nearby
- IF the distance to the next patrol point is "far enough" (no one seems to know how far, far enough is!)
They will ride the patrol, instead of walking it.
I have got this to work ... I just needed to have a large enough distance in between the patrol points
(best of luck
