Inherited By: VisibleOnScreenEnabler3D
Detects approximately when the node is visible on screen.
The VisibleOnScreenNotifier3D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a Camera3D's view.
If you want nodes to be disabled automatically when they exit the screen, use VisibleOnScreenEnabler3D instead.
Note: VisibleOnScreenNotifier3D 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 Area3D node as a child of a Camera3D node and/or Vector3.dot.
screen_entered ( )
Emitted when the VisibleOnScreenNotifier3D enters the screen.
screen_exited ( )
Emitted when the VisibleOnScreenNotifier3D exits the screen.
The VisibleOnScreenNotifier3D's bounding box.
bool is_on_screen ( ) const
true, the bounding box is on the screen.
Note: It takes one frame for the node's visibility to be assessed once added to the scene tree, so this method will return
false right after it is instantiated, even if it will be on screen in the draw pass.
