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).
