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.
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).
A little over a year ago (in June of 2011), I went over the Corona Event Model, and explained exactly what events are in Corona, when they occur, and how you can “hook” into them to take advantage of some of Corona’s best features.
However, in the previous article, I kept the subject-matter focused on the built-in events associated with specific API’s that are provided out-of-the-box in Corona. What I didn’t mention is that you can define your own custom events, and have objects listen for when those events are dispatched (which you have complete control over as well).
This tutorial will walk you through defining and dispatching custom events, so you can begin applying the knowledge to your own games and apps.
This week’s tutorial is going to be a little different. Rather than go over yet another awesome Corona feature, I’ll instead be walking you through another aspect of Corona development that’s arguably just as important (if not more important) than any one specific feature of the SDK. What you’ll be learning about today is something you’ll undoubtedly use in every single Corona project you work on, and that is of course is the Corona SDK API Reference.
EDITOR’S NOTE: This tutorial is outdated and has been replaced by a new guide: Masking Images. Please refer to this guide for details and usage examples. In this week’s tutorial, I’m going to cover a feature that, while infinitely useful for many projects, you may not even be aware exists because of its specialized use-cases. […]
When developing applications, it’s important to handle scenarios that occur as a result of the user interacting with your game in as many different ways possible. It’s equally as important to handle scenarios that occur as a result of “system” events, whether they are explicitly triggered by the user or not. Things that immediately come […]
For those who don’t know what LFS is, it’s a popular Lua library that allows you to perform common file system activities that can’t normally be done in plain Lua. Things like getting file attributes, creating and removing directories (folders), and iterating over files in a directory are all things that can be easily done […]
If you know what events are Corona (if you don’t, you should start here), then you know that they allow you to “do something” whenever a specific action that corresponds to an event occurs. You can even define your own actions, and dispatch custom events whenever it is appropriate for your app. However, no events […]
One of the two most-requested items in regards to the Storyboard API was the ability to pass custom data between scenes as you switched between them, and also some kind of “pop up” feature, where a scene can be loaded and displayed above another scene, leaving the currently active scene intact. The documentation for both […]
Lights… camera… CUT! Corona’s Storyboard API has been around for a while now, but there is still some confusion among the community in regards to how to use it. And while I’m sure that my recent explanation of the various events associated with the Storyboard API certainly helped a little, perhaps an explanation of the […]
