About three weeks ago, I was invited to attend the launch event of Barnes & Noble’s new NOOKcolor. I had read a lot of information about the device, and was eager to see what all the hoopla was about. Three months prior to the B&N event, I had visited Samsung to see the new Galaxy Tab and yet again, here I was at the prospect of yet another Android tablet ready to saturate the already saturated tablet market. While at the launch event, I bumped into some old friends from Adobe as well as the leadership of the mobile unit at B&N. Ted Patrick, Chief Evangelist – Developer Relations for NOOK, had invited me to the event and I was eager to track him down so

(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

Being in the mobile industry, we regularly come across companies who are looking to have their own mobile apps. Sometimes, they ask us if we would make an app for them using Corona, and we usually have to decline since our focus is in creating the SDK’s, not the apps. Companies and game studios don’t just want any app, they want an app that has maximum performance across a multitude of devices without having to spend extra money to go cross-platform. When they hear about Corona, they immediately see it as the most cost-effective option for them without having to sacrifice functionality. And that’s where you come in! Over the past several months, we’ve quietly began building out a Studio Directory of Corona developers to whom

Last month, we talked to Mark Sigal of Unicorn Labs about his eBook Rabbit and Turtle’s Amazing Race for iPad. At that time, Rabbit and Turtle had already cracked the Top 10 on the App Store’s list of top free eBooks. Since then, it has been featured by Apple on the iPad front page and gone on to become the #12 top-grossing (that means paid!) eBook for iPad. Naturally, people wanted to know Mark and Unicorn’s secret to making a best-selling eBook. So, yesterday he penned a guest piece for the O’Reilly Radar offering his insight from creating the top-selling Rabbit and Turtle, and gives plenty of praise to Corona in doing so. You can read the full piece by clicking the screenshot below: “Rabbit and

After Tim’s introduction to the newly revitalized Corona Comics yesterday, we thought we’d waste no time in showing you how to make your own iPad comics. One of the most important elements of comic books is word balloons. In the video below, artist Dwayne Ferguson of DieHard Studio Entertainment walks you through the process of creating word balloons for your comics using art software that most of you already have. Dwayne will be contributing more tutorials like this from now on, so all you aspiring iComic artists might want to check in regularly for those!

Blocfall by Thomas Claburn is an addictive game recalling the arcade classics of yesteryear. Your challenge is to clear each level of falling blocks by tapping the highest block on the screen until all of them are gone. The blocks begin in a row and fall. Tapping the highest block will remove it and add points to your score. OpenFeint integration allows you to compare your score against people around the world. Doodle Sheep by Instant Mash Games is another comical, arcade-style game. Save the sheep from being sheared by the oncoming scissors by pressing the name of the colour of the scissors. It may not be as easy as it seems as the color names are not on top of the correct colors. As you

We’ve been working diligently on a brand new audio engine for Corona which we will hope you will love. Our new engine is built from the ground-up, on top of the industry standard, OpenAL, which is designed for low-latency, high performance mixing, and a darling technology of the video game industry. We have many features planned for our new audio engine, but here is a tiny taste of it. In our prior sound engine, you could only play one “streaming” sample at a time. Our new engine no longer arbitrarily limits you to the number of streams you can play. So if you had large files like background music and speech you needed to play at the same time, you would have a hard time.
