XNA 3.0小例子
MS昨天发布了XNA Game Studio 3.0游戏开发工具的首个社区技术预览版(CTP),以下是一些相关信息。
XNA Game Studio 3.0正式版预计到今年年底才会发布,目前的CTP预览版仅支持Zune游戏开发,尚不支持Xbox 360游戏。除了Zune游戏外,该开发工具还能够访问Zune播放器中存储的非DRM保护音乐,允许开发者自定义游戏背景音乐,或开发出实时音乐虚拟游戏等等。另外,使用它开发的游戏还能够支持ad-hoc点对点互联,支持多台Zune无线联机对战。
XNA Game Studio 3.0 CTP仅支持32位Windows系统,需要Visual Studio 2008 Standard Edition或以上开发环境的支持(必须安装C#,或至少安装Visual C# 2008 Express Edition)。现在网络上已经有首批Zune游戏放出,可以通过XNA Game Studio 3.0 CTP在Zune上安装试玩。
我也来看下热闹
