This week’s tutorial discusses the Corona “physics contact,” a method that allows you to access a specific collision — and four new properties pertaining to it — before the collision actually occurs.
A common question from Corona developers is: “How can I read data stored in a remote database and put it into my app?” Corona Ambassador and author Brian Burton illustrates one convenient method in this week’s Tuesday Tutorial.
Predetermining your transition “frames” is another useful trick if you want to squeeze every ounce of performance out of your code. This week’s tutorial from Corona veteran Omid Ahourai shows you exactly how with the implementation of his custom “AK-tween” library.
The Widgets 2.0 library is now available to users with access to Daily Builds. All new widgets share a common trait: each has been written atop a new foundation that is more flexible and stable. Today’s tutorial discusses two of these: “switch” and “segmented control”. Please read further to learn how these new widgets can enhance the user interface of your app.
Today’s tutorial covers Corona blend modes using the “object.blendMode” API, and illustrates how to use them for creative visual effects within your app. Whether you want to achieve a glowing effect like fire or a subtle shadow effect, blend modes can be a powerful tool in your Corona arsenal. This tutorial steps you through the three Corona blend modes, the effect of each, and the technical algorithms involved.
In this week’s Tuesday Tutorial, Corona Ambassador Brent Sorrentino explores the basics of parallax scrolling and walks you through a demo project to implement a customizable touch-and-drag parallax view in your app.
Today’s guest tutorial comes to you courtesy of Omid Ahourai, an indie game developer who goes by the alias “ArdentKid.” He’s been working with Corona SDK for over two years and will soon release his first highly-anticipated game, “Balloon Bazooka.” Please check out his work and blog at www.ardentkid.com.
Tuesday Tutorials are back! Today’s tutorial is from Brent Sorrentino, a Corona Ambassador based in northern Colorado. Brent has been an active part of the Corona community for almost two years. He is a freelance travel photographer, Corona developer, and graphic designer. In addition to using Corona to develop his own apps, he regularly lends a hand in the forums, helping other developers solve coding issues.
The iPhone 5 is looking like it will be the fastest-selling gadget of all time. So let’s talk about what you need to do to prepare your Corona apps for the iPhone 5 and iOS6.
One of the biggies we’ll cover is what you’ll need to do to make your Corona app handle the new 16:9 aspect ratio, or what we’re calling “tall apps” (as opposed to the shorter “traditional apps” designed for the iPhone 3 and iPhone 4).
There’s often confusion as to what exactly happens when external modules are “required” into your code, which leads to further confusion and unexpected behavior when it comes to things such as Storyboard Scenes or even custom modules of your own.
Today I’m going to guide you through a series of exercises (with explanations) that should illustrate exactly how modules work in Lua, so you get a full understanding of when the code in your modules is executed, including what code is not run when you call the built-in require() function.
