More on XNA Game Studio 4.0 and Windows Phone Support
Says the Klucher through the tweets of The Shawn:
Demo [Harvest, developed by Luma Arcade] looks awesome, full 3D, animating characters. More will be shown at MIX next week.
The game loop on the phone is similar to existing platforms, but tweaked for power efficiency.
The phone graphics is an evolution of the existing immediate mode rendering API, 2D and 3D:
- New configurable effects: BasicEffect, SkinnedEffect, EnvironmentMapEffect, DualTextureEffect, AlphaTestEffect
- Custom programmable shaders are not supported on the phone
- Image scaler:
- lets you render to any size backbuffer, and have this automatically scaled to fill the screen
- lets the same game run on both 800x480 and 480x320 display sizes without special coding
- provides automatic rotation to support portrait, landscape left, and landscape right modes
- the image scaler is free: it uses dedicated hardware so does not consume any GPU
Portability: the ability to target three screens. Portability lets you target more sockets with a smaller time investment. Portability is not just about the same game running on different platforms, it is also valuable to share infrastructure, knowledge, etc.
Framework feature profiles:
- Reach: broad base of devices including phones
- HiDef: Windows and Xbox only
“Focus on being a game developer, not plumbing the underlying technology”
“Michael Klucher plugs forums.xna.com, says our MVP's are awesome and do a great job answering questions.”
“Michael Klucher gets applause!”
The will be more talk about the Marketplace and the Windows Phone emulator at the MIX next week.
XACT is part of the HiDef feature profile, so not on the phone: use SoundEffect (+ 4.0 enhancements) on the phone.
Ozymandias has an article about how to get in touch with Microsoft to get access to Xbox LIVE on the phone.
Update (2010-03-11 02:31 GMT): The Shawn has another blog post up, high-level-detailing some Windows Phone support related work done.
