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
Traditional update/draw/
present frame loop
Core programming model consistent
with previous releases
Changes implemented yield better
power performance on devices
System integration with
Windows Phone 7 best practices
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
Translated to existing
XNA Framework concepts
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
BasicEffect
SkinnedEffect
New configurable effect
classes on all platforms
Custom effects not available on
Windows Phone 7
EnvironmentMapEffect
DualTextureEffect
AlphaTestEffect
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
Audio Capture and Playback
Simple API to play back WAV data
Modify pitch, volume, pan audio
Ability to play synthesized/buffered audio
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);
Serialize captured data
Provides more control over System.Media
types on Windows Phone 7
}
Audio Playback Example
Microphone/Bluetooth Support
Playback through headset
Capture through mic or headset
// Load a sound effect from a raw stream
SoundEffect effect1 =
SoundEffect.FromStream(GetStreamFromTheWeb("http://url.wav"));
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();
Music Enumeration and Playback
Control and enumerate users’
media within a game
Ability to play songs from URI/URL
(i.e. music app)
URI Song Playback Example
// Constructs a song from a URI
Uri mediaStreamUri = new Uri("http://song.asx");
Song streamedSong = Song.FromUri("Song",
mediaStreamUri);
// Play the song
MediaPlayer.Play(streamedSong);
Picture Enumeration and Playback
Supports photo picking/editing/publishing
Video Playback
Uses standard video player API
Show/Hide controls
Retrieve Image Data
MediaLibrary media = new MediaLibrary();
// Get the JPEG image data
Stream myJpegImage = ReadAndModifyPicture(somePicture);
// Save texture to Media Library
media.SavePicture("Awesome", myJpegImage);
Input / Touch
Cross Platform Input API
Xbox 360 Controllers
(Xbox/Windows)
Touch Input Handling
Keyboard
(Xbox/Windows/Windows Phone 7)
var touchCollection = TouchPanel.GetState();
Touch API
//...
Available across platforms for portability
(fewer #ifdefs)
foreach (var touchLocation in touchCollection)
{
if (touchLocation.State ==
TouchLocationState.Released)
{
//...
}
}
