Windows Phone 7– A new beginning Xbox LIVE overview XNA Game Studio 4.0 Powerful, Productive, Portable XNA Framework Call to action and resources

Without Xbox LIVE You can still write and publish games for Windows Phone Create great games for marketplace We’re interested in your great games! Find a publisher! Lots to choose from!

Consistent sets of hardware capabilities defined by Microsoft Resolution Touch Input CPU / GPU RAM Hardware keyboard is optional

Modern XAML/event-driven application UI framework Rapid creation of visually rich apps HTML/Javascript Mature, robust, widely deployed technology GAMES (and applications) APPLICATIONS (and games)

Powerful Productive Portable

Makes game development easier XNA Framework provides robust APIs for games C#,.NET and Visual Studio tooling Solutions for game content processing Not an engine solution Creating Games

Develop for Windows Phone 7 Series Simplified graphics API’s Visual Studio 2010 integration Enhanced audio support New configurable effects

Powerful

Uses the.NET platform Windows Phone 7 Managed code platform, no unsafe code XNA Game Studio 4.0 is C# exclusive 800+ managed code games on XBLA/XBLIG Windows games published through portals.NET/XNA is used for games today!

Frameworks designed for performance XNA Framework designed for gaming scenarios Commitment to future of managed code No unnecessary garbage generation Math libraries optimized Efficient APIs with tuned transitions to native code Three + years of profiling and investment We’ve built for performance on Windows Phone 7

Productive

Productive development with.NET and C# High performance IDE Intellisense makes coding faster Integrated build/deploy/debug experience MSBuild engine for build automation

Manage assets in Visual Studio Importers for common game data formats Optimize data into binary format for efficient loading Fully extensible XNA Framework/Game Loop not required Content projects external in XNA Game Studio 4.0

XNA Framework

The XNA Framework Game Loop is layered on top of the Silverlight Application object on Windows Phone 7 Provides the bulk of integration of API’s Most of the XNA Framework can be accessed from Silverlight applications Including Gamer Services (Xbox LIVE) In this release some sharing/composition is not complete Scenes using GraphicsDevice from XNA Framework and UIElements from Silverlight You’ll want to choose the technology that works best for your scenarios

Graphics UI control heavy consider Silverlight Desire vector graphics in XAML Media Rich video support in application Tooling If you use Microsoft Blend in your pipeline

Graphics Using 3D graphics Sprite heavy 2D applications should consider the XNA Framework Game Loop Simulation/Drawing Those who prefer a traditional update/ draw/present frame loop Tooling Those who want to use the XNA Framework Content Pipeline graphics types

XNA Framework Game Loop Example System integration with Windows Phone 7 best practices Translated to existing XNA Framework concepts Traditional update/draw/ present frame loop Core programming model consistent with previous releases Changes implemented yield better power performance on devices protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here base.Draw(gameTime); }

Graphics

Evolution of our existing immediate mode rendering API Simplifies for resource and render state management Feature segmentation between “Reach”/“HiDef” profiles Rendering primitives 2D and 3D

New configurable effect classes on all platforms BasicEffect SkinnedEffect EnvironmentMapEffect DualTextureEffect AlphaTestEffect Custom effects not available on Windows Phone 7

Write your game without worrying about native resolution or orientation Automatic rotation between portrait and landscape Touch automatically supports both scale and orientation changes Scaler can drastically improve performance Trade off performance for “crispness” and shade fewer pixels 800x480 = 384,000 pixels, 480x320 = 153,600 pixels Upsample an arbitrary back buffer to native device resolution Far higher quality than bilinear filtering Allows for easier porting from other platforms Scaling/Rotation comes for “free” from Hardware

Audio & Media

Audio Capture Example public void EventDrivenCapture() { mic = Microphone.Default; buffer = new byte[mic.GetSampleSizeInBytes(mic.BufferDuration)]; mic.BufferReady += new EventHandler(OnBufferReady); DynamicPlayback = new DynamicSoundEffectInstance(mic.SampleRate, AudioChannels.Mono); } public void OnBufferReady(object sender, EventArgs args) { // Get the latest captured audio. int duration = mic.GetData(buffer); // Do some post-capture processing and playback. MakeMeSoundLikeARobot(buffer, duration); DynamicPlayback.SubmitBuffer(buffer); } Audio Capture and Playback Simple API to play back WAV data Modify pitch, volume, pan audio Ability to play synthesized/buffered audio Serialize captured data Provides more control over System.Media types on Windows Phone 7 Microphone/Bluetooth Support Playback through headset Capture through mic or headset Audio Playback Example // Load a sound effect from a raw stream SoundEffect effect1 = SoundEffect.FromStream(GetStreamFromTheWeb(" effect1.Play(); // Create dynamic audio on the fly byte[] fluteSound = GetFluteNote(); effect2 = new SoundEffect(fluteSound, SampleRate, AudioChannels.Stereo); SoundEffectInstance instance = effect2.CreateInstance(); instance.Pan = -1; instance.Pitch = 1.5f; instance.Play();

URI Song Playback Example Retrieve Image Data Music Enumeration and Playback // Constructs a song from a URI Uri mediaStreamUri = new Uri(" Song streamedSong = Song.FromUri("Song", mediaStreamUri); // Play the song MediaPlayer.Play(streamedSong); MediaLibrary media = new MediaLibrary(); // Get the JPEG image data Stream myJpegImage = ReadAndModifyPicture(somePicture); // Save texture to Media Library media.SavePicture("Awesome", myJpegImage); Picture Enumeration and Playback Video Playback Control and enumerate users’ media within a game Ability to play songs from URI/URL (i.e. music app) Supports photo picking/editing/publishing Uses standard video player API Show/Hide controls

Input / Touch

Touch Input Handling Cross Platform Input API Touch API Xbox 360 Controllers (Xbox/Windows) Keyboard (Xbox/Windows/Windows Phone 7) Available across platforms for portability (fewer #ifdefs) Multipoint on Windows Phone 7 and Windows Orientation and resolution aware Developer can override var touchCollection = TouchPanel.GetState(); //... foreach (var touchLocation in touchCollection) { if (touchLocation.State == TouchLocationState.Released) { //... }

Sensors

Accelerometer Example VibrationExample Leverage Platform Features on Windows Phone 7 Location Accelerometer Vibration Accelerometer accelerometer = new Accelerometer(); accelerometer.ReadingChanged += AccelerometerReadingChanged; accelerometer.Start(); VibrateController rumbler; rumbler.Start(TimeSpan.FromSeconds(2));
