Use dynamic layouts in universal builds with Corona SDK

Posted by & filed under Corona SDK, Tutorials, Tips and Demos, 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

Posted by & filed under Tutorials, Tips and Demos.

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

Flash to Corona SDK Porting Guide

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

CAUTION: This tutorial is outdated and the material cannot be confirmed as accurate. A new guide covering this topic is coming soon. 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 export all your graphical assets. When porting from Flash Lite on older devices, I generally recreated higher-resolution assets for the larger iPhone and Android screens. However, web-based Flash games will likely have assets that are already a good size for today’s mobile devices. And of course, if the assets are vector-based, you

Corona SDK Tutorial: Polygon point reduction with curve-fitting

Posted by & filed under Corona SDK, Tech, Tutorials, Tips and Demos.

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)

Content Scaling Made Easy

Posted by & filed under Tech, Training/Support, Tutorials, Tips and Demos.

(Read the follow up: Dynamic Image Resolution Made Easy) Content scaling is a very useful feature of Corona, but it’s one that I’ve found myself explaining frequently. In this post, I’ll try to boil it down to the essentials, and demonstrate how to easily target multiple screens from the same code and assets. The problem Mobile device screens now come in many different shapes and sizes. At one extreme, the iPad screen is 768 x 1024, for a 1 : 1.33 aspect ratio. Meanwhile, the Motorola Droid (480 x 854) and Samsung Galaxy Tab (600 x 1024) have aspect ratios greater than 1 : 1.7. In plain English, the iPad is more square than the iPhone, and most Android devices are taller and skinner than
