  3. Agenda • Windows Phone 7 • Mobile Games • Silverlight vs. XNA • Introduction to XNA • Live Coding Sample • More on XNA • Mango Demo • Outlook and Q&A

  4. Windows Phone 7 • Microsoft's new mobile platform • Again, it's a mobile platform • Limited CPU power • Limited GPU power • Slower file system I/O • Network bandwidth limitations • Don't be paranoid, but careful and considerate • Don't ever trust the emulator

  5. Mobile Games • Biggest market share for WP7 • Similar numbers for iOS + Android • High demand from consumers • Interesting chance for developers

  6. Silverlight vs. XNA • Two equally treated frameworks • Technologies can (partly) be mixed • No requirement to use XNA for games(you can use Silverlight for games too) • Use Silverlight if the included controls, animation or layout system is more effective • Use XNA for more complex games and for its unique selling points like 3D rendering • Generally only do simple/static games in Silverlight • Mind the upcoming Mango update

  7. XNA (1) • Managed environment,but focuses on performance • More comfort = less performance • XNA has none of Silverlight's comfort • No declarative UI (XAML) • No layout system • No animation system • No data binding • No built-in controls and themes/styles • No sophisticated text rendering

  8. XNA (2) • Different programming paradigm to Silverlight • Puts you in an "active" roleinstead of a passive consumer • Game loop as the central driving construct • Update: Handling input, executing logic • Draw: Rendering all the content to the screen • "Think incrementally"

  9. Live Coding Sample

  10. XNA (3) • Lack of comfort makes some things really hard • User interfaces (menus, option screens etc.) • Good looking text rendering (line wrapping etc.) • Complex screen layout (e.g. lists of data, scrolling) • User input (no text box etc., no SIP) • One possible solution: the Mango update • Mixing Silverlight and XNA in the same application • Comes at the cost of worse portability

  11. Mango Demo

  12. Outlook • XNA is much more than what we learned today • 3D, Sound and music, multi-touch input, etc. • Additional non-technical topics • Full training also covers not so common topics: • Chances and limitations of an indie developer • Sharing experience from commercial game projects • Monetizing options • And a lot more…

  13. Q&A

  14. Thank you for attending.
