A box-shaped region of 3D space that detects whether it is visible on screen.


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.

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.




AABB(-1, -1, -1, 2, 2, 2)



is_on_screen ( ) const


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)

  • void set_aabb ( AABB value )

  • AABB get_aabb ( )

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.
