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_property_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_property_scroll_offset>`.

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

.. _class_ParallaxBackground_property_scroll_base_offset:

- :ref:`Vector2<class_Vector2>` **scroll_base_offset**

+----------+-------------------------------+
| *Setter* | set_scroll_base_offset(value) |
+----------+-------------------------------+
| *Getter* | get_scroll_base_offset()      |
+----------+-------------------------------+

Base position offset of all :ref:`ParallaxLayer<class_ParallaxLayer>` children.

.. _class_ParallaxBackground_property_scroll_base_scale:

- :ref:`Vector2<class_Vector2>` **scroll_base_scale**

+----------+------------------------------+
| *Setter* | set_scroll_base_scale(value) |
+----------+------------------------------+
| *Getter* | get_scroll_base_scale()      |
+----------+------------------------------+

Base motion scale of all :ref:`ParallaxLayer<class_ParallaxLayer>` children.

.. _class_ParallaxBackground_property_scroll_ignore_camera_zoom:

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

+----------+-------------------------------+
| *Setter* | set_ignore_camera_zoom(value) |
+----------+-------------------------------+
| *Getter* | is_ignore_camera_zoom()       |
+----------+-------------------------------+

If ``true``, elements in :ref:`ParallaxLayer<class_ParallaxLayer>` child aren't affected by the zoom level of the camera.

.. _class_ParallaxBackground_property_scroll_limit_begin:

- :ref:`Vector2<class_Vector2>` **scroll_limit_begin**

+----------+------------------------+
| *Setter* | set_limit_begin(value) |
+----------+------------------------+
| *Getter* | get_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_property_scroll_limit_end>` to work.

.. _class_ParallaxBackground_property_scroll_limit_end:

- :ref:`Vector2<class_Vector2>` **scroll_limit_end**

+----------+----------------------+
| *Setter* | set_limit_end(value) |
+----------+----------------------+
| *Getter* | get_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_property_scroll_limit_begin>` to work.

.. _class_ParallaxBackground_property_scroll_offset:

- :ref:`Vector2<class_Vector2>` **scroll_offset**

+----------+--------------------------+
| *Setter* | set_scroll_offset(value) |
+----------+--------------------------+
| *Getter* | get_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.
