Tutorial to add a loading screen

Hello,
Is there a tutorial out there to add a loading screen? I would like to show a progress counter (from 1 to 100%) and load all the resources so the game is smoother to play. I looked at gamescratch.com but couldn’t find anything.
Thanks

Please refer to cc.LoaderScene in file CCLoader.js .

It defines a logo image in base64 and draws a progress counter, you may custom it as you want.
