A box-shaped region of 3D space that detects whether it is visible on screen.
[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 [signal screen_entered] signal, and likewise it will emit a [signal 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]. [b]Note:[/b] [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 [member Node3D.visible] is set to [code]true[/code].
Returns [code]true[/code] if the bounding box is on the screen. [b]Note:[/b] It takes one frame for the [VisibleOnScreenNotifier3D]'s visibility to be assessed once added to the scene tree, so this method will always return [code]false[/code] right after it is instantiated.
- The [VisibleOnScreenNotifier3D]'s bounding box.
Emitted when the [VisibleOnScreenNotifier3D] enters the screen.
Emitted when the [VisibleOnScreenNotifier3D] exits the screen.
