This is an idea I concocted from another post suggesting the ability for kids to get lost in Pizzeria's and stuff and it's basically the Mapper for the Surveillance Package except for everything else apart of the core mod.
It would be a way of specifying where exactly you would want your animatronics to even roam, like maybe you want them to be able to access everything but one open room like a Safe Room or something, you could select rooms and remove individual pieces of places you want them to be "Allowed" to roam into alongside other stuff like maybe determining who can go where like have a way of deciding who goes down a corridor to the left or not like how in FNaF 1, Bonnie is the only one other than Foxy who can go down there while the Freddy and Chica can't.
It'd give some more control over what exactly the Animatronic Night AI can do.
