+				Set the physics layers this area is in.
+				Collidable objects can exist in any of 32 different layers. These layers are not visual, but more of a tagging system instead. A collidable can use these layers/tags to select with which objects it can collide, using [method set_collision_mask].
+				A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A.
