i want to make static npcs. Someone know the script?

SetActorsAI 0 to freeze them completely, SetGhost 1 if you don't want to be able to still beat them to death, "is pushable" (or something like that) ticked in the NPC's properties so you can't push their collision mesh away from their frozen appearance. There was also mention of SetRestrained, but I'm not sure what it does and if it's necessary for this method (It was mentioned in tandem with giving the NPC a constant paralyze effect, maybe effects Havok? Dunno).

Setrestrained makes them unable to walk away.

Ah, so I guess you could use that if SetActorsAI 0 doesn't let them equip armor? Though does it stop all animations like SetActorsAI 0?

No, they can still fight and all, just not walk away. Makes for great snipers or guards.
