A node used to create a parallax scrolling background.
</brief_description>
<description>
A ParallaxBackground will use one or more [ParallaxLayer] nodes to create a parallax scrolling background. Each [ParallaxLayer] can be set to move at different speeds relative to the camera movement, this can be used to create an illusion of depth in a 2D game.
A ParallaxBackground uses one or more [ParallaxLayer] child nodes to create a parallax effect. Each [ParallaxLayer] can move at a different speed using [member ParallaxLayer.motion_offset]. This creates an illusion of depth in a 2D game. If not used with a [Camera2D], you must manually calculate the [member scroll_offset].

A parallax scrolling layer to be used with [ParallaxBackground].
</brief_description>
<description>
A ParallaxLayer must be the child of a [ParallaxBackground] node. All child nodes will be affected by the parallax scrolling of this layer.
A ParallaxLayer must be the child of a [ParallaxBackground] node. Each ParallaxLayer can be set to move at different speeds relative to the camera movement or the [member ParallaxBackground.scroll_offset] value.
This node's children will be affected by its scroll offset.
