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)

Guest Post: Corona SDK and eBooks, a match made in app heaven!

Posted by & filed under Corona SDK, Education, Guest Bloggers.

Unicorn Labs‘ Mark Sigal talks about the evolution of eBooks, and just how Corona SDK allowed him and his team to create our latest App — err — eBook of the Week, Rabbit and Turtle’s Amazing Race. For more from Mark, you can also check out a past interview and a quick blogpost we’ve done mentioning him and Unicorn Labs. I have written in the past about where I think eBooks are headed (“Rebooting the book”), but the essence is this:  Just as the advent of sound in motion pictures transformed not only how films were made, but also what they were and the economics behind them, such is the future for the book business and print media in general. Yet, the eBook business, as it exists

Martian Control: ANOTHER open source game made with Corona SDK!

Posted by & filed under Corona SDK, News & Announcements, Tech.

Beebe Games’ open source Angry Birds replica Ghosts vs. Monsters was such a hit with the Corona community that they decided to do it all over again! This time, they have created a clone of the popular iPhone game Flight Control, redubbing it Martian Control. The Beebes’ created their game in an astonishing 30-hour timeframe, with Biffy handling artwork and Jon handling the programming, as usual. For more details on the process, be sure to check out Jon’s blog. The source code for Martian Control is immediately available at the Corona Code Exchange. Below, you can watch a video demo of the open source game, which Jon assures us “gets choppy at times, but don’t worry, it’s just the video. Actual gameplay is very smooth and works

Corona SDK: New additions and overhauls

Posted by & filed under Corona SDK, News & Announcements.

As our users know, we’re always focused on delivering the best new Corona features for them to use. Since our product is on a subscription basis, we literally work year-round to keep it on top of the latest developments in the rapidly changing mobile space. Earlier this year, we created Corona Game Edition to offer our more advanced features to users who were interested specifically in mobile game development. However, over the past several months, we’ve noticed that everyone (whether they make simple apps or advanced games) wants those heavy-duty features in their utility belts. So, the divided product line is no more!
