VisibleOnScreenNotifier3D
Inherits: VisualInstance3D < Node3D < Node < Object
Inherited By: VisibleOnScreenEnabler3D
A box-shaped region of 3D space that detects whether it is visible on screen.
Description
VisibleOnScreenNotifier3D represents a box-shaped region of 3D space. When any part of this region becomes visible on screen or in a Camera3D's view, it will emit a screen_entered signal, and likewise it will emit a screen_exited signal when no part of it remains visible.
If you want a node to be enabled automatically when this region is visible on screen, use VisibleOnScreenEnabler3D.
\ Note: VisibleOnScreenNotifier3D uses an approximate heuristic that doesn't take walls and other occlusion into account, unless occlusion culling is used. It also won't function unless Node3D.visible is set to true.

Signals
screen_entered\ (\ ) 🔗
Emitted when the VisibleOnScreenNotifier3D enters the screen.
screen_exited\ (\ ) 🔗
Emitted when the VisibleOnScreenNotifier3D exits the screen.
Property Descriptions
AABB aabb = AABB(-1, -1, -1, 2, 2, 2) 🔗
The VisibleOnScreenNotifier3D's bounding box.
Method Descriptions
bool is_on_screen\ (\ ) const 🔗
Returns true if the bounding box is on the screen.
\ Note: It takes one frame for the VisibleOnScreenNotifier3D's visibility to be assessed once added to the scene tree, so this method will always return false right after it is instantiated.
