VisibleOnScreenEnabler3D 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.
Emitted when the VisibleOnScreenNotifier3D enters the screen.
Emitted when the VisibleOnScreenNotifier3D exits the screen.
The VisibleOnScreenNotifier3D's bounding box.
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.
