public abstract class Node2D
extends Node

A specialised version of the Node class that works in 2D screen space only.

This class is the base class for all 2D renderable nodes in the SceneGraph. Although bounds are in a full 3D space using the normal bounding volume objects, the user can assume that the depth (Z axis) values are always ignored.

2D geometry uses the screen coordinate space that is the same as Viewports. The origin is in the lower left corner of the viewport with positive width to left and positive height up.
