ParallaxLayer
=============

**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A parallax scrolling layer to be used with :ref:`ParallaxBackground<class_ParallaxBackground>`.

.. rst-class:: classref-introduction-group

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

A ParallaxLayer must be the child of a :ref:`ParallaxBackground<class_ParallaxBackground>` node. Each ParallaxLayer can be set to move at different speeds relative to the camera movement or the :ref:`ParallaxBackground.scroll_offset<class_ParallaxBackground_property_scroll_offset>` value.

This node's children will be affected by its scroll offset.

\ **Note:** Any changes to this node's position and scale made after it enters the scene will be ignored.

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

.. _class_ParallaxLayer_property_motion_mirroring:

.. rst-class:: classref-property

:ref:`Vector2<class_Vector2>` **motion_mirroring** = ``Vector2(0, 0)``

.. rst-class:: classref-property-setget

- void **set_mirroring** **(** :ref:`Vector2<class_Vector2>` value **)**
- :ref:`Vector2<class_Vector2>` **get_mirroring** **(** **)**

The ParallaxLayer's :ref:`Texture2D<class_Texture2D>` repeating. Useful for creating an infinite scrolling background. If an axis is set to ``0``, the :ref:`Texture2D<class_Texture2D>` will not be repeated.

If the length of the viewport axis is bigger than twice the repeated axis size, it will not repeat infinitely, as the parallax layer only draws 2 instances of the texture at any given time.

\ **Note:** Despite its name, the texture will not be mirrored, it will simply be repeated.

.. _class_ParallaxLayer_property_motion_offset:

.. rst-class:: classref-property

:ref:`Vector2<class_Vector2>` **motion_offset** = ``Vector2(0, 0)``

.. rst-class:: classref-property-setget

- void **set_motion_offset** **(** :ref:`Vector2<class_Vector2>` value **)**
- :ref:`Vector2<class_Vector2>` **get_motion_offset** **(** **)**

The ParallaxLayer's offset relative to the parent ParallaxBackground's :ref:`ParallaxBackground.scroll_offset<class_ParallaxBackground_property_scroll_offset>`.

.. rst-class:: classref-item-separator

----

.. _class_ParallaxLayer_property_motion_scale:

.. rst-class:: classref-property

:ref:`Vector2<class_Vector2>` **motion_scale** = ``Vector2(1, 1)``

.. rst-class:: classref-property-setget

- void **set_motion_scale** **(** :ref:`Vector2<class_Vector2>` value **)**
- :ref:`Vector2<class_Vector2>` **get_motion_scale** **(** **)**

Multiplies the ParallaxLayer's motion. If an axis is set to ``0``, it will not scroll.
