What is the Delta Engine? Develop with .NET for all AppStore platforms No need to learn different and dated languages for different platforms such as iPhone, Android and WP7 Easy to learn and to build Use your favorite Windows-tools, check out our examples and just press the magic button to build for other platforms Lightweight and fast We did the hard work to optimize performance for all platforms - just include the parts you need for your game Teamwork made easy With our advanced content management system, editors for game designers and full support of all your favorite tools Assets and code are Open Source The Delta Engine and our example games are Open Source and you are invited to participate or to integrate other libraries 6

ZombieParty runs already on many Platforms October 2010 9

Why Multiplatform? • 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) 10

Why Multiplatform? 2003 2009 2011 PC Consoles Mobile PC Consoles Mobile PC Consoles Mobile 3% 17% 23% 31% 53% 57% 30% 20% 66% 11

Why Multiplatform?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. 10 bn USD (2015)Sell many apps on many platforms! 1 bn USD (2009) 12

Why is our engine different? • 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 13

Platforms and Languages • 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, …) 14

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

Extremely Open Engine • 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 17

Launcher Addin for VS• Directly integrated into Visual Studio 2010• Also available as Standalone App for Testers e.g. Start Unit Tests• Starts programs, games, tests, tutoria ls, samples on all supported devices• Also shows lots of information about your project 18

Content, Content, Content • Todays 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 19

Content, Content, Content• 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 20

Content, Content, ContentStep 1: Add Content file to Content ProjectStep 2: Load and use content in code 20

Content, Content, Content• 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 20

Content, Content, Content• 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) 21

Content, Content, Content• 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 22
