The document introduces MobileBits GmbH and their multiplatform game development engine called the Delta Engine. The Delta Engine allows developers to create games using .NET and deploy them with one click to various platforms including iPhone, Android, Windows Phone 7 and more. It aims to make multiplatform game development easier by eliminating the need to learn different languages for each platform.

5. 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

10. 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)

12. 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

13. 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

14. 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, …)

17. 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

18. 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

19. Content, Content, Content
• 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
19

20. 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

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

22. 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

23. 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

24. 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

Example Atlas Textures (generated automatically, 2D & 3D)
