+	</brief_description>
+	<description>
+		A [Parallax2D] is used to create a parallax effect. It can move at a different speed relative to the camera movement using [member scroll_scale]. This creates an illusion of depth in a 2D game. If manual scrolling is desired, the [Camera2D] position can be ignored with [member ignore_camera_scroll].
+		[b]Note:[/b] Any changes to this node's position made after it enters the scene tree will be overridden if [member ignore_camera_scroll] is [code]false[/code] or [member screen_offset] is modified.
