I'm making an NPC mod and I'm trying to prevent the NPC from going through doors. The NPC has various AI packages that make it wander around, eat, drink, sleep, ... The NPC should never leave the room where I put it (using a summon spell) but I haven't found a way to prevent the NPC from leaving the room. Any suggestions? Thanks

Actors with an intelligence of 30 and above will be able to follow through doors. SO give him\her an Int of less than 30 and they will not use doors.

Thanks! That seemed to have helped. Does setting intelligence this low have other (unwanted) side effects?
