But There’s More Interesting game codebases rely on other components These “middleware” components are critical to: Accelerate time to market, reduce risk, increase stability Simplify shipping across devices/screens (Developing “Cross-Microsoft Platform”) Both open source technologies and commercial tech We’ve partnered with the community to ensure these work well on Windows 8

Open Source Technologies

Link in the pre-built lib binaries Be sure to get a Windows 8.1 version for use in 8.1 apps Build the source in your environment Then you can see how it works and tune to your scenario Using Open Source

We’ve made great starting points for Windows Store games VS.sln solutions & Windows Store SDK API usage Samples ported to Windows Store projects Ported UI code in samples to XAML Implementations pass certification & work well on ARM This enables you to spend your energy on the game Microsoft’s Community Contributions

Open source OpenGL ES2 API wrapper Enables easy transition from iOS or Android Used by many popular products Originally built on Direct3D9, Now updated to Direct3D11 for Windows Store Runtime shader compiles work in Windows ANGLE – Almost Native GL Engine

Angle Asteroids

Popular engine for sprite games on phones 1000s of games already shipped Runs on Windows 8 phone, Windows RT, Windows 8, etc. Cocos2D-x

Full 3D rendering engine Rich shader capabilities for photorealism Includes native Direct3D module since starting Used in: Ankh by Deck13, and Torchlight by Runic, etc. Runs on Windows Phone OGRE - OO Graphics Rendering Engine

OGRE Screenshots

SharpDX Efficient C# bindings to DirectX APIs Low-level Direct3D access for best C# performance Includes basic input, audio, file loading, etc. Using C#?

Are there other open source projects you need? Feedback

Commercial Technologies

Commercial Middleware

We’ve built partnerships to bring commercial technologies to the Windows Store Range of pricing models You get commercial support, some include source code Most support custom plug-ins, scripting, etc. Game Engines Renderers Physics Network Services Audio Commercial Technologies

Unity 3D

Agora Hydra

Share Contract Link to your own store page Windows Azure Easy to roll up a very basic service Xbox Live great if you are coming from xbox Other Connectivity Options

Popular physics library Now includes Vision 3D rendering engine, destruction, AI, and cloth modules Supports the whole Microsoft ecosystem Havok for Windows 8 and Windows Phone 8 Havok

Commercial implementation of OpenGL ES on Direct3D Includes a full native C++ game API set Runs on Windows Phone too 8 Marmalade

Full IDE for game creation Asset marketplace Game Salad

Graphine

Several APIs available on Windows 8/Phone 8 Unity plug-in, iOS and Android support Autodesk products

Maya 3D Studio Content Creation Tools

The most commonly used games middleware is available for Windows 8 store apps Both open source and commercial middleware! Go for it! Conclusion: The Ecosystem is Ready

Update to the latest versions of any middleware components Set up a Windows 8.1 build environment and build Optimize performance/Tune for device feature levels Add in cool new Windows features like: Contracts, live tiles, and notifications, overlays, etc. Ship!
