  1. iPhone Game Development By Andres Acevedo Undergrad Student, College of Arts and Sciences University of Miami

  2. Introduction • Previous knowledge in Java • Idea of creating a game • What type of game? • What do I need to do that?

  3. Introduction (cont) • iPhone Game Development • To overcome: • No Macintosh • No previous knowledge in iPhone development • No knowledge in objective-C programming

  4. Structure of Presentation • Part I: Hardware requirements and possible solutions • Part II: Setting up projects using Xcode SDK and Interface Builder • Part III: Cocos2D Framework for developing iPhone games

  5. Part I Hardware requirement (and Possible solutions) • Development must be done in a Macintosh machine • Intel based Processor • Updated version of OS X • Leopard (10.5.7) or later to install SDK

  6. Web based application frameworks • Phonegap & Appcelerator • HTML, Javascript, CSS, etc. • Install Mac OS X on my PC • OSX86 project • Multiple methods of installation Hardware requirement (and Possible solutions)

  7. Hacking Methods • Kernel Hacks • Boot loader and Emulators • Live DVD • (www.insanelymac.com) Hardware requirement (and Possible solutions)

  8. Part II Setting up projects using Xcode SDK and Interface Builder

  9. Xcode tools package • Xcode IDE • Interface Builder (IB) • iPhone Simulator Setting up projects using Xcode SDK and Interface Builder

  10. Xcode IDE • Source code supported natively: • C, C++, Fortran, objective-C, Java, AppleScript, Python and Ruby • iPhone apps: cocoa touch (objective-C language) Setting up projects using Xcode SDK and Interface Builder

  11. Cocoa touch Classes • Implementation Files • Header Files Setting up projects using Xcode SDK and Interface Builder

  12. Interface Builder • Buttons, sliders, menus, etc Setting up projects using Xcode SDK and Interface Builder

  13. iPhone Simulator • Virtual phone • No accelerometer • No camera • Note: While testing in the simulator execution time might not be the same! Setting up projects using Xcode SDK and Interface Builder

  14. When to execute actions? • Different types of touches! • Touch up inside • Touch drag outside • Touch drag exit Setting up projects using Xcode SDK and Interface Builder

  15. To consider when Writing iPhone apps • One application at a time (besides OS) • One window • Limited response time • Limited screen size and resources • Screen : 480 x 320 • Processor: 600 mhz • Memory 256 MB • Storage 32 GB Setting up projects using Xcode SDK and Interface Builder

  16. Part III Cocos2D Framework

  17. Cocos2D Key features • Transitions between scenes • Sprite & sprite sheet creation • Effects (lens, ripple, waves, twirl, etc..) • Actions (rotation, movement, rev movement) • Menus, Buttons (customized) • Particle system Cocos2D Framework

  18. Basic concepts to understand when using cocos2D • Scenes • Director • Layer • Sprites Cocos2D Framework

  19. Scene Cocos2D Framework

  20. Director Cocos2D Framework

  21. Layers Cocos2D Framework

  22. Sprites Cocos2D Framework

  23. Conclusion • Solutions to develop iPhone apps • Concepts of Xcode and Interface Builder • Cocos2D to assist game development

  24. Thank you!
