 		The VisibilityEnabler will disable [RigidBody] and [AnimationPlayer] nodes when they are not visible. It will only affect other nodes within the same scene as the VisibilityEnabler itself.
 		If you just want to receive notifications, use [VisibilityNotifier] instead.

The heuristic is an implementation detail and may change in future versions. If you need precise visibility checking, use another method such as adding an [Area] node as a child of a [Camera] node and/or [method Vector3.dot].

 		The VisibilityNotifier detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a [Camera]'s view.
 		If you want nodes to be disabled automatically when they exit the screen, use [VisibilityEnabler] instead.
