Description
|
|
-----------
|
|
|
|
**VisibleOnScreenNotifier3D** represents a box-shaped region of 3D space. When any part of this region becomes visible on screen or in a :ref:`Camera3D<class_Camera3D>`'s view, it will emit a :ref:`screen_entered<class_VisibleOnScreenNotifier3D_signal_screen_entered>` signal, and likewise it will emit a :ref:`screen_exited<class_VisibleOnScreenNotifier3D_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 :ref:`VisibleOnScreenEnabler3D<class_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 :ref:`Node3D.visible<class_Node3D_property_visible>` is set to ``true``.

Method Descriptions

.. _class_VisibleOnScreenNotifier3D_method_is_on_screen:

:ref:`bool<class_bool>` **is_on_screen**\ (\ ) |const| :ref:`🔗<class_VisibleOnScreenNotifier3D_method_is_on_screen>`
|
|
|
|
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.
