VisibilityEnabler
=================

**Inherits:** :ref:`VisibilityNotifier<class_VisibilityNotifier>` **<** :ref:`CullInstance<class_CullInstance>` **<** :ref:`Spatial<class_Spatial>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Enables certain nodes only when approximately visible.

.. rst-class:: classref-introduction-group

Description
-----------

The VisibilityEnabler will disable :ref:`RigidBody<class_RigidBody>` and :ref:`AnimationPlayer<class_AnimationPlayer>` nodes when they are not visible. It will only affect other nodes within the same scene as the VisibilityEnabler itself.

If you just want to receive notifications, use :ref:`VisibilityNotifier<class_VisibilityNotifier>` instead.

\ **Note:** VisibilityEnabler uses an approximate heuristic for performance reasons. It doesn't take walls and other occlusion into account (unless you are using :ref:`Portal<class_Portal>`\ s). The heuristic is an implementation detail and may change in future versions. If you need precise visibility checking, use another method such as adding an :ref:`Area<class_Area>` node as a child of a :ref:`Camera<class_Camera>` node and/or :ref:`Vector3.dot<class_Vector3_method_dot>`.

\ **Note:** VisibilityEnabler will not affect nodes added after scene initialization.

.. rst-class:: classref-method

void **set_enabler** **(** :ref:`Enabler<enum_VisibilityEnabler_Enabler>` enabler, :ref:`bool<class_bool>` enabled **)**

Sets active state of the enabler identified by given :ref:`Enabler<enum_VisibilityEnabler_Enabler>` constant.
