When your creation is ready to show to your friends and family you will want to publish it to the Arcade. Once it has been published you will be able to play it from the Arcade screen instead of going to the Coding Editor. Think of published projects as “Finished” and unpublished projects as “Work in progress”.
You can publish your project by pressing the “Details” button on the coding screen, filling the form in so that people know how to play your game and then pressing the “Publish to Arcade” button.
If you want to make changes to a published project you should go to the Coding Editor, press the “Published” tab, press your project and then press the “Unpublish Project” button.
You cannot share a project to another person’s Games Studio app. Projects are only available on the iPad they were created on.
