1: No, Bonnie and Chica don’t have the same AI, Bonnie can teleport anywhere he wants on the left cameras and Chica can only move in adjacent rooms forward or backwards.
I think they could be made with repeaters that check for the night number property (look in the “timer” dropdown) and roll a randomizer to check if they’ll move.
2: Freddy’s AI could be made by wiring the prop that is freddy to a zone which locks freddy from moving because he doesn’t move when you are in the same camera as him.
(Look at the cameras dropdown)
3: Foxy’s AI could be made with a counter linked to a property that increases every time you look at the cams.
The Repeater runs a trigger which checks if the property is more than #.
If the property is more than #, foxy will be locked and won’t move.
If # is more than the property, foxy will move onto the next stage
(I don’t know if this is correct, don’t really understand Foxy’s AI that much)
