ParallaxBackground
==================

**Inherits:** :ref:`CanvasLayer<class_canvaslayer>` **<** :ref:`Node<class_node>` **<** :ref:`Object<class_object>`

**Category:** Core

Brief Description
-----------------

A node used to create a parallax scrolling background.

Member Variables
----------------

  .. _class_ParallaxBackground_scroll_base_offset:

- :ref:`Vector2<class_vector2>` **scroll_base_offset** - Base position offset of all :ref:`ParallaxLayer<class_parallaxlayer>` children.

  .. _class_ParallaxBackground_scroll_base_scale:

- :ref:`Vector2<class_vector2>` **scroll_base_scale** - Base motion scale of all :ref:`ParallaxLayer<class_parallaxlayer>` children.

  .. _class_ParallaxBackground_scroll_ignore_camera_zoom:

- :ref:`bool<class_bool>` **scroll_ignore_camera_zoom** - If ``true`` elements in :ref:`ParallaxLayer<class_parallaxlayer>` child aren't affected by the zoom level of the camera.

  .. _class_ParallaxBackground_scroll_limit_begin:

- :ref:`Vector2<class_vector2>` **scroll_limit_begin** - Top left limits for scrolling to begin. If the camera is outside of this limit the background will stop scrolling. Must be lower than :ref:`scroll_limit_end<class_ParallaxBackground_scroll_limit_end>` to work.

  .. _class_ParallaxBackground_scroll_limit_end:

- :ref:`Vector2<class_vector2>` **scroll_limit_end** - Right bottom limits for scrolling to end. If the camera is outside of this limit the background will stop scrolling. Must be higher than :ref:`scroll_limit_begin<class_ParallaxBackground_scroll_limit_begin>` to work.

  .. _class_ParallaxBackground_scroll_offset:

- :ref:`Vector2<class_vector2>` **scroll_offset** - The ParallaxBackground's scroll value. Calculated automatically when using a :ref:`Camera2D<class_camera2d>`, but can be used to manually manage scrolling when no camera is present.


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

A ParallaxBackground uses one or more :ref:`ParallaxLayer<class_parallaxlayer>` child nodes to create a parallax effect. Each :ref:`ParallaxLayer<class_parallaxlayer>` can move at a different speed using :ref:`ParallaxLayer.motion_offset<class_ParallaxLayer_motion_offset>`. This creates an illusion of depth in a 2D game. If not used with a :ref:`Camera2D<class_camera2d>`, you must manually calculate the :ref:`scroll_offset<class_ParallaxBackground_scroll_offset>`.
