Unified EditorUnity is now the best editor for multi-platform projects. The new Build Settings window lets you set your primary Editor Mode or build to any of your target platforms. NewPlatform Defines let you include or exclude code for a specific platform at compile-time, so you can work with one project and one set of scripts.

高度集成的编辑器环境

untiy 3可以针对多种平台使用同一项目文件。新的发布设置面板可以设置编辑器模式或者针对特定平台进行发布。新的目标平台定义选项可以很方便的在编译时包括或者排除不同平台所用到的特定代码部分，因此使用者可以基于同一项目并针对多平台进行发布！
