10. Why Multiplatform? 10 Past: Only Windows Game Development Recent: Shift towards Consoles, iPhone Present: One platform or all platforms Most teams still focus on one platform Or you need an engine to be on many platforms Examples: Unreal Engine 3 (Consoles) Unity (mostly iPhone) XNA Framework (mostly Xbox 360)

11. Why Multiplatform? 11

12. Why Multiplatform? 12 1 bn USD (2009) 10 bn USD (2015) Why not just develop iPhone Games? Mobile game market is shifting towards Android and WP7 And growing on all platforms and devices (e.g. tablets this year) Most apps are games (iPhone, Android, WP7), but usually costs only 99 cents. Sell many apps on many platforms!

13. Why is our engine different? 13 Most other engines are either: Black boxes (Unity, UDK, Editors, Modding) Just graphic frameworks for specific platforms (DirectX, XNA, OpenGL ES) Or huge native code engines with high license costs (only suitable for big teams: Unreal, CryEngine, etc) We like.NET, it allows more rapid development! Only recently possible on all platforms Xbox 360, WP7, Windows -> Microsoft iPhone, Android, Linux, Mac -> Novell

14. Platforms and Languages 14 Most platforms have specific frameworks and usually only support 1-2 languages well: iPhone: Objective-C (not very pretty) Android: Java (lots of config files, can compile C too) Windows Phone 7: Only C# (Silverlight or XNA) Xbox 360: Native C++ (XDK, or C# with XNA, Xbla) PS3, Wii: C++ (have their own frameworks, ES) Linux: Mostly C++ (gcc), Java, also.NET (Mono) MacOS: Objective C and C++ mostly Windows can do everything (.NET, Java, Scripts, …)

15. C++ vs C# (setup graphics) 13

16. 16 Unity Editor Game Code Game Assets Unity Engine Modules & Features (not customizable) Unity3D: Closed ModelDelta Engine: Open Model Delta Engine Framework Game Code Game Assets Delta Engine Modules Third Party Engine Modules Custom Modules Black Boxes (Closed)Customizable (Open) Open Source vs Proprietary

17. Extremely Open Engine 17 Source code available for free (starting July 2011) Develop and publish your games on Windows No costs for you! If you want to deploy on any other platform than Windows: You need a Delta Engine Multiplatform license Access to easy to use tools (Launcher, Simulators) Which will be cheap or royalty based, no worries One click deploy, fast and easy with the Launcher

18. Launcher Addin for VS 18 e.g. Start Unit Tests Directly integrated into Visual Studio 2010 Also available as Standalone App for Testers Starts programs, games, tests, tutorials, samples on all supported devices Also shows lots of information about your project (Tests, Assemblies, Todo-List, etc.)

19. Content, Content, Content 19 Today's games are mostly content driven Especially on Consoles and PC You usually have a powerful engine ready to go Sharing content between games was almost impossible in the past, formats changed too often The Delta Engine makes all content always available and will always work on all supported platforms

20. Content, Content, Content 20 Example with XNA on Windows Phone 7 Artist saves.png image file or 3D Model Content pipeline converts all files to.xnb.xnb is the only format allowed for WP7 Images are best stored as DDS files XNA’s content pipeline does the conversion for you 3D Models or Levels often need custom importers because of different needs

21. Content, Content, Content 20 Step 1: Add Content file to Content Project Step 2: Load and use content in code

22. Content, Content, Content 20 Many content files depend on each other usually With the Delta Engine it works very similar and on all platforms, content is just not needed at compile time! Things get more complex if you add more platforms

23. Content, Content, Content 21 When testing on Windows needs 1-2 files per content Makes no sense to keep all formats for all platforms. Converting formats takes time. For example a single 2048x2048 iPhone PVR Texture takes 30-40 seconds to save on really fast PC with 3.6Ghz (we got hundreds) So content is only converted when you actually need it and it has been changed (cache) Content is processed on Servers in the Cloud (currently one server can handle everything, but this will be expanded as more demand is needed)

24. Content, Content, Content 22 Content is always automatically requested and build, there is no button to do it and a human will make too many mistakes choosing options anyway. Instead the build server decides all this and makes sure all content files work together, optimized as much as possible Unused content is removed, Atlas textures are generated, content is optimized by the shaders used Crazy compression rates of 100:1 and more, which is really required for mobile games (ZombieHockey 2.8MB on WP7, 6 MB iPhone, PC version is 40MB, uncompressed >120MB)

25. Content, Content, Content 23 Example Atlas Textures (generated automatically, 2D & 3D)

26. Delta Engine Release 24 Questions? I hope you liked the presentation and the Engine. Delta Engine Release July 2011 (v0.9) v1.0 coming end 2011 www.DeltaEngine.net Already working on Windows, MacOS, Linux, iPhone, iPad, Windows Phone 7, Android, Android Tablets, Nvidia Tegra, Xbox 360 and more soon
