## Overview

Overview SKNode provides base properties for its subclasses and it can be used as a container or layout tool for other nodes. For example, you might add a collection of nodes as children to an SKNode that all move together within the scene; because nodes inherit the properties of their parent, changing the parent node’s position propagates the change to its children as well. SKNode does not draw any content itself. Its visual counterparts are listed in Nodes that Draw in Nodes for Scene Building.
