Class

SKReferenceNode

A node that's defined in an archived .sks file.

Declaration

class SKReferenceNode : SKNode

Overview

SKReferenceNode is used within an archived .sks file to refer to node defined in another .sks file without duplicating its definition. This way, a change to the referenced node propagates to all the references in other files.

As an example, you might want to share an enemy ship across two different levels, Scene1.sks and Scene2.sks, in a level-based game. Reference nodes allow you to do that without creating copies of the shared node and its properties.

To use a reference node:

  • Create the shared content in a separate archive

  • Add references to the shared archive within your scene archives

When each scene is loaded, the reference nodes are resolved dynamically, and therefore you only need to configure a shared object in one place.
