Something that isn’t clear by studying Corona’s included SampleCode or any of the other examples and tutorials on this website is the concept of organizing projects. We’ve sort of just let you know that everything goes into your project folder and sent you off on your way—and oh, sub-folders are supported. That’s about all we’ve said on the subject up until now.
However, as your projects get bigger, that may not be quite enough. With more and more resources are being added to your project, such as audio files, images, videos, Lua modules, etc. it can add a whole new layer of complexity to the development process—complexity that isn’t at all necessary.
This tutorial is by no means the end-all to Corona SDK project organization techniques, but it will introduce you to an effective one that you can tweak at your heart’s content to suit your needs perfectly.
