Use dynamic layouts in universal builds with Corona SDK

Posted by & filed under Corona SDK, Tutorials, Videos.

Universal Builds are a feature I’m really excited about in the latest version of Corona SDK. There are some great possibilities that you can take advantage of in your apps with Universal Builds in Corona SDK. Corona SDK can do some amazing things with dynamic content scaling and dynamic image resolution to make sure your graphics look sharp on hi-res screens. What I’d like to add is that you can have dynamic layouts on different devices as well. Where I Last Left Off A while back I posted a tutorial on the blog, “Create scrolling list views with text and graphics in Corona”. Then I posted an update to show how easy it would be to modify so that the same code that you used

Third-party tools for Corona SDK: SpriteDeck

Posted by & filed under Tutorials.

The big news this week, of course, is our Corona SDK on Windows release. However, we also announced a myriad of third-party tools that also are now available for Corona, created by brilliant users like yourself. So, now, we’ll be showcasing a new tool each day. First up is SpriteDeck, which brings the easy drag-and-drop option of game creation to Corona. SpriteDeck‘s beauty lies in what it especially brings to the field of iPad comics with its drag-and-drop interface. A quick low-down on that can be seen below: SpriteDeck currently is available for $49.00 USD, but founder Zee Yang just informed us that coupon codes can be obtained directly from him via e-mail. (See? Sometimes it pays off to read all the way to the end of

Dynamic Image Resolution Made Easy

Posted by & filed under Corona SDK, Tech, Training/Support, Tutorials.

When Corona SDK was first released to the public in December 2009, there was only one device screen to target: the iPhone at 320 x 480 resolution. Corona for Symbian had been set aside due to the iPhone’s overwhelming popularity, and Android wasn’t the “next big thing” yet. In 2011, mobile developers need to consider a rapidly growing set of screen sizes, shapes, resolutions and pixel densities. Corona now addresses this in two ways. (1) Content scaling automatically expands (or shrinks) the entire Corona stage so that your content fills different screens. This topic won’t be covered here, but you can read a full discussion of content scaling in this earlier post. (2) In addition, you can employ dynamic image resolution, which will automatically replace

But wait, there's more!

With all the excitement about the Windows Beta, the really awesome 3rd party tools, and the new Indie iOS price point, it’s easy to miss all the cool new features we added to plain ol’ Corona. So let’s walk through them and show some code: In-app purchase In the movie All the President’s Men, Deep Throat tells Woodward to “follow the money”, so let’s start with in-app purchase (IAP). There’s a more extensive walkthrough here, but I’ll just show you a brief code snippet so you get the gist. To access it you use the new store module. On the coding side, there’s basically 3 steps: Initialize the store: This is just loading the store module and registering a transaction listener. Load valid products: You

Flash to Corona SDK Porting Guide

Posted by & filed under Corona SDK, Flash, Lua, Tech, Training/Support, Tutorials.

Back in the distant days of 2009, I gave a presentation called “From Flash Lite to Ansca Corona”, detailing case studies of mobile apps that I’d ported. Those slides have since been viewed thousands of times, but I’ve been promising for months to write a more detailed guide, featuring more specific Flash porting techniques. Also, Corona has changed significantly since those days — many of today’s key Corona features didn’t even exist in 2009. This article is designed to get Flash developers quickly oriented within Corona. First, I’ll discuss how to take your existing Flash projects and turn them into Corona projects, followed by a more general introduction to Corona from a Flash perspective. (1) Exporting Assets from Flash A good first step is to

Corona SDK Tutorial: Polygon point reduction with curve-fitting

Posted by & filed under Corona SDK, Tech, Tutorials.

Using a variant of the Douglas-Peucker algorithm in conjunction with the curve-fitting algorithm by Philip J. Schneider found in Graphics Gems I, Carlos wrote this in Corona SDK using nothing but the Corona framework to draw, reduce points, and convert the resulting polyline into a series of cubic bezier curve segments. Sample code coming soon! (you can bug Carlos if you want it immediately, though)
