Simple states example

[samme]

• There is only one file/script.
• The states are simple objects (no prototype).
• Three states: Boot, Menu, Game. You move through them with Start, Restart, and Quit.
• Fun features:
  • Loading bar with setPreloadSprite
  • loadUpdate, loadRender, pause, render, and shutdown callbacks
  • Logs state changes with onStateChange signal so you can see what's happening
