Signals
-------
.. _class_VisibilityNotifier2D_signal_screen_entered:

Emitted when the VisibilityNotifier2D enters the screen.

Emitted when the VisibilityNotifier2D exits the screen.
----
.. _class_VisibilityNotifier2D_signal_viewport_entered:
- **viewport_entered** **(** :ref:`Viewport<class_Viewport>` viewport **)**
Emitted when the VisibilityNotifier2D enters a :ref:`Viewport<class_Viewport>`'s view.
----
.. _class_VisibilityNotifier2D_signal_viewport_exited:
- **viewport_exited** **(** :ref:`Viewport<class_Viewport>` viewport **)**
Emitted when the VisibilityNotifier2D exits a :ref:`Viewport<class_Viewport>`'s view.
Description
-----------
The VisibilityNotifier2D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a viewport.
Property Descriptions
---------------------
.. _class_VisibilityNotifier2D_property_rect:
- :ref:`Rect2<class_Rect2>` **rect**
+----------+-----------------+
| *Setter* | set_rect(value) |
+----------+-----------------+
| *Getter* | get_rect() |
+----------+-----------------+
The VisibilityNotifier2D's bounding rectangle.
Method Descriptions
-------------------
.. _class_VisibilityNotifier2D_method_is_on_screen:
- :ref:`bool<class_bool>` **is_on_screen** **(** **)** const
If ``true``, the bounding rectangle is on the screen.
Note: It takes one frame for the node's visibility to be assessed once added to the scene tree, so this method will return ``false`` right after it is instantiated, even if it will be on screen in the draw pass.
