VisibilityNotifier

    Inherited By:

    Detects approximately when the node is visible on screen.

    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.

    Note: VisibilityNotifier uses an approximate heuristic for performance reasons. It doesn’t take walls and other occlusion into account. 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 node as a child of a Camera node and/or .
