CanvasLayer
===========

**Inherits:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`ParallaxBackground<class_ParallaxBackground>`

Canvas drawing layer.

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

Canvas drawing layer. :ref:`CanvasItem<class_CanvasItem>` nodes that are direct or indirect children of a ``CanvasLayer`` will be drawn in that layer. The layer is a numeric index that defines the draw order. The default 2D scene renders with index 0, so a ``CanvasLayer`` with index -1 will be drawn below, and one with index 1 will be drawn above. This is very useful for HUDs (in layer 1+ or above), or backgrounds (in layer -1 or below).

+-----------------------+----------------------------------------------------------------------------+

Property Descriptions
---------------------

.. _class_CanvasLayer_property_custom_viewport:

- :ref:`Node<class_Node>` **custom_viewport**

+----------+----------------------------+
| *Setter* | set_custom_viewport(value) |
+----------+----------------------------+
| *Getter* | get_custom_viewport()      |
+----------+----------------------------+

The custom :ref:`Viewport<class_Viewport>` node assigned to the ``CanvasLayer``. If ``null``, uses the default viewport instead.

----

.. _class_CanvasLayer_property_follow_viewport_enable:

- :ref:`bool<class_bool>` **follow_viewport_enable**

+-----------+----------------------------+
| *Default* | ``false``                  |
+-----------+----------------------------+
| *Setter*  | set_follow_viewport(value) |
+-----------+----------------------------+
| *Getter*  | is_following_viewport()    |
+-----------+----------------------------+

Sets the layer to follow the viewport in order to simulate a pseudo 3D effect.

----

.. _class_CanvasLayer_property_follow_viewport_scale:

- :ref:`float<class_float>` **follow_viewport_scale**

+-----------+----------------------------------+
