Overview

A Scene is a container for one independent state of your application, like title screen, in-game, pause menu, ...

A Scene contains Spaces.

Scenes live on an App's scene stack, while only the topmost scene is updated and rendered. This means that you can e. g. push your pause scene onto the stack and pop it off later and your ingame scene will get paused automatically. You could also implement a system that updates and/or renders other scenes, so that your pause scene shows your game in the background.

Example usage:

sc = Scene.new
sc << Space.new("ui", ...)
sc << Space.new("game", ...)
app << sc
