3. Social Gaming with Windows Phone and Azure Daron Yondem Chief Architect | DEVELOAD Software Microsof Regional Director Silverlight MVP INETA MEA President
4. Daron Yöndem is • Silverlight MVP • Microsoft Regional Director for MEA • INETA MEA President • Book Author about HTML5, ASP.NET AJAX, Silverlight • Architect at DEVELOAD Software • Blog at http://daron.yondem.com
5. DEVELOAD is • Consulting – Software architecture and design – Custom software development of Windows, Web Windows Phone, Azure and Silverlight applications – Mentoring services to get you started and keep you going • Web site: www.deveload.com
6. You Are... • Interested in building WP7 Games • Wondering what Cloud computing can offer to help your serve millions of gamers?
7. Let’s start with... • What Cloud computing can offer? • What we have in hand with Windows Azure? • What kind of integration scenarios can happen between WP7 and Azure. • How can Azure help me fascilitade building Social Games reacing millions of people?
8. Why Phone + Cloud? • The cloud levels the playing field • The cloud provides a larger pool of resources from which to pull • The cloud provides a way to reach across device platforms
9. Why WP7 and Windows Azure? • PaaS: you build it, Windows Azure runs it • Automatic O/S patching • Scalable • Utility billing • Additional services (e.g. ACS, Traffic Manager, Caching, CDN, etc.) • Common development tools – Visual Studio – Languages – Emulators for development
10. Identity
11. Identity Options • Create your own (e.g. username + password, token) – Custom model – ASP.NET Membership Providers • Use a single existing identity system (e.g. Live Id, Facebook, etc.) • Outsource identity management (e.g. Access Control Service)
12. To learn more … Authenticating Users in a Windows Phone 7 App via Access Control Service, OData Services and Windows Azure http://bit.ly/wp7acs
13. Storage
14. Storage • SQL Azure – Relational database – Highly available – Managed for you as a service • Windows Azure Tables – Non-relational structured storage – Massive scale-out – OData • Windows Azure Blobs – Big files – REST
15. SQL Azure: OData Service • Client sends data to web role • Web role stores data in SQL Azure Web Role (1) (2)
16. Windows Azure Blobs: Public Blobs • Client sends data to web role • Web role stores data in blobs • Client fetches public blobs directly Web Role (1) (2) (3)
17. Windows Azure Blobs: SAS • Client gets Shared Access Signature from web role • Client stores data in blobs • Client fetches public blobs directly Web Role
18. Windows Azure Tables: Proxy Calls • Client sends data to web role • Web role stores data in blobs Web Role
19. Do not store your secrets on the phone
20. Services
21. Web Role versus Worker Role • Web Role has IIS • Worker Role does not – DLL with Main() • Both implement the RoleEntryPoint
22. Scaling Work in Windows Azure 1. Web role receives message 2. Web role enqueues work 3. Worker role polls queue 4. Worker role sends notifications MPNS Worker Role Web Role (1) (2) (3) (4)
23. Multitenancy • You can have more than one application running in your role instance
24. Content Delivery Network CD N CD N CD N CD N CD N CD N
25. Communications
26. Communications • Two communication models – Phone-initiated – Cloud-initiated
27. Phone-Initiated Communication Options • HTTP-based, request/response • Framework choices (WCF, OData, WebRequest, etc.) • Wire format choices (SOAP, JSON, POX, etc.)
28. Cloud-Initiated Communication • Push Notifications – Single connection between phone and Microsoft Push Notification Service – Bandwidth- and battery-friendly – No guarantee of delivery • Three kinds of push notifications – Raw – send a message to an application – Toast – send a message to the user – Tile – update an image, title, or count
29. Subscribing to Push Notifications • Phone opens a channel • Phone sends URL to cloud • Cloud pushes notifications via URL • Microsoft Push Notification service notifies phone MPNS Web Role
30. Let’s go on with... • How can we build social games with Silverlight? • Performance Tips and Tricks
31. First : Performance!
32. Threading • UIThread – PerFrame Callbacks, Touch, Networking, User Code, Layout • RenderThread (Composition Thread) – Opacity, DoubleAnimations, Perspective Transforms, Rectangular Clips, RenderTransforms • Worker Threads
33. • Application.Current.Host.Settings. • EnableFrameRateCounter = true; Fillrate
34. Application.Current.Host.Settings.EnableRedrawRegions = true;
35. Application.Current.Host.Settings.EnableCacheVisualization= true;
36. Performance Strategy Minimize UI Thread Work Leverage Off-Thread Use the GPU Less is more!
37. CacheMode = BitmapCache
38. Visibility OR Opacity?
39. JPEG or PNG? Faster Decoding Opacity
40. XAML or Pictures?
41. App Start-Up Delay Loading the Unneeded! Include applicationsplashscreen.jpg Use a splash screen
42. DON’T! Non-rectangular clips Large textures ( > 2K pixels either way) Complex animations (e.g. ColorAnimation) Opacity mask
43. Second: How To?
44. Step 1 : Timer • CompositionTarget.Rendering – Frame Animations • DispatchTimer – It’s inside the UIThread • StoryBoard • System.Thread.Timer public partial class Page : UserControl { System.Threading.Timer Sayac; public Page() { InitializeComponent(); Sayac = new System.Threading.Timer(Tick, TOP, 500, 500); } public void Tick(object sender) { ((Ellipse)sender).Dispatcher.BeginInvoke(delegate() { ((Ellipse)sender).Height += 1; }); } }
45. Step 2 : Graphics • 2D games easy to build inside Silverlight • What about 3D? – Kit3D - http://www.markdawson.org/kit3d/ – Balder - http://www.codeplex.com/Balder – XNA! • You can create a whole new 3D world!
46. Step 3 : Audio • Windows Media Audio and MP3 support. • XNA Libraries to play effects and wma files. • MediaElement can help you for background music. • You can even have live streams in your game!
47. Final Step: Pyhsics • Farseer Pyhsics Engine – It’s for both Silverlight and XNA! – Includes helpers and behaviors easy to use inside Expression Blend!
48. In Conclusion • Azure and Cloud – Helps us serve millions of gamers with web/worker roles, CDN, SQL Azure, Notification Services – Azure Toolkit for Windows Phone helps us there. • Performanca and tactics for WP7 game development – Composition Thread, DoubleAnimations, Performance Counter and so on. – Using Dispatcher and StoryBoards together.
