Tutorial: Using System Events to Save App State

Something that’s becoming increasingly popular is the ability to “pick up where you left off” or stop and resume with hardly any friction. More and more, apps are starting off exactly how you left them—and that doesn’t exclude mobile apps (in fact, mobile is arguably what inspired this behavior).

Having your apps start off where your user left them is also known as “state saving”, and that’s exactly what I’m going to cover in this tutorial. As with any tutorial that’s posted here, I encourage you to take what you learn and build upon or modify the code to suit the specific needs of your app.

Best Practices for Organizing Projects

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.

Join us for lunch!

As Corona keeps on growing, we want to make sure we keep our fingers on the pulse of the Corona community and the exceptional apps our developers are creating. We also love getting very direct and honest feedback on Corona – and the best feedback comes from the developers who are banging away at the platform day after day.

To accomplish this, we’re excited to announce the Corona Developer Lunch! On a few days each month (usually Thursdays) we’ll invite 1-2 developers/studios to our office for lunch and a session of feedback on their apps/games and our platform.

Properly Removing Objects and Variables

Removing objects and getting rid of unneeded variables may seem trivial, but it’s actually common question among Corona newcomers and veterans alike.

The potential consequences of doing this simple-but-important task incorrectly can lead to memory leaks, app slowdowns, and even crashes (which you don’t want, obviously).
