Rapid Game Development with Corona SDK discusses the Corona SDK which allows developers to quickly and easily write mobile games and graphical apps for iOS and Android using the Lua programming language. It highlights success stories of apps developed with Corona, what the SDK provides like graphics hardware acceleration and physics engines, and its benefits like high productivity, cross-platform development, and an active developer community. Limitations include some missing native platform features and when not to use Corona for business apps requiring deep native integration. Sample code, tools, and the presenter's experiences with app development are also covered.

9. What is Corona? A cross development mobile sdk from AnscaMobile (http://www.anscamobile.com) An SDK that empowers developers to write mobile games and graphical rich apps for iOS and Android, quickly, and easily. Corona produced apps have been downloaded 22m times Corona apps are approved for the Nook Platform. Price – USD 349 per year to publish for both iOS and Android. Free Trial forever.

10. Success Stories Bubble Ball 14 yr old – Robert Nay (> 7m Downloads) Float – Crawl Space games ~ 1 million downloads; one day to prototype; 2 months to develop Blast Monkeys – > 300K downloads: created in 14 days

11. What is the SDK? Lua Interpreter (110KB interpreter) Open GL – ES 2.0 (graphics hardware acceleration standard) Open AL Physics engine built around Box2D Native C, C++ libraries (injected at runtime depending on the platform)

12. Things we love about the SDK Huge Productivity Gains Cross Platform Ability for iOS and Android Simple, effective Dev environment and workflow Helpful and active community API keeps expanding Physics and other Framework support Lots of sample code and third party tools Migration path from Flash to Corona

13. Productivity Displaying an image Objective C (iOS) Java (Android) Corona sdk (both platforms) Display.newImage(“myImage.png”) Display.newImageRect(“myImage.png”,1024,768)

14. Simple and effective dev workflow Projects are kept separate folders Assets are compiled into app App Code starts in the “main.lua” Code Editors of your choice: Text Wrangler, BBEdit, Xcode, Notepad ++ .. Works on Windows and Mac Compilation does not happen locally!

15. Cross Platform Development Support for Nook in the Final stages. More Platforms – in the future

16. SDK is good at 2-D Games Graphical-oriented Utilities Rapid Prototyping Apps which are graphical in nature

17. Catch the Ball – Game Prototype Backgrounds Physics Collisions Story: basketballs dropping from the sky Use a basket (hoop) to catch them Don’t catch bombs, but catch a special bonus ball Scoring: + 1 for each basketball, +5 for special bonus, -2 for bomb You have 10 lives, each time you drop a ball life decreases.

18. Limitations of the SDK Android Only 2.2 or higher Android Armv7 only. iOS notifications not available Android inapp purchase – not available iAds only possible through a workaround Some iOS features don’t work yet on android when not to use If you need native code integration and 3rd party toolkits integrated If you need a business app with native device UI controls targeting both platforms

19. Sample Code available And Much More..

20. What about Lua? Lua is small As small as <100 KB (DLL/LIB) Easy runs on small devices or in small apps. Lua is simple to use To use-well suited for small software To learn- ~20 keywords, ~20 operators Powerful arrays Lua is fast Apart from this, dynamic typing first class functions, easy interop, written in C, ample libraries.

21. Benefits to game developers SDK is easy to use; powerful with 500 APIs Lua , fast powerful and easy to use language Ability to publish to both iOS and Android Animation and sprite techniques Physics engine inApp purchases for both iOS inMobi and Papaya Mobile Ad networks Dynamic Content Scaling File manipulation, xml / JSON parsing, SqlLite Reusable frameworks and code available from community – Director, Memory monitor etc Social integration, Launchpad, partnership with inMobi and Papayamobile Native Device Features(accelerometer, gyroscope, GPS, MAPS, async http

22. Tools for game developers Spriteloq – convert Flash animations to Corona Kwik – Photoshop CS5 plugin to create comics, storybooks from psd files CPM – Corona Project Manager to manage your projects Particle Candy – professional effects for games Lime – include tilemaps created in Tiled

24. Native UI look

25. Limited to what the SDK has to offer.

26. Both platforms may not have common elements
