 		The VisibilityEnabler2D will disable [RigidBody2D], [AnimationPlayer], and other nodes when they are not visible. It will only affect nodes with the same root node as the VisibilityEnabler2D, and the root node itself.

 		The VisibilityNotifier2D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a viewport.
