界面是游戏中必不可少的一部分，就算你进入游戏没有看到什么UI窗口，你也不必着急，因为多多少少都会有隐藏着的界面等你去体验。一个好的UI大部分应该归功于设计的人与提供美术支持的人员，因为他们是直接设计UI的人，而程序只提供一些显示的功能支持。本次用到的UI渲染为开源的CEGUI，想必很多做游戏的朋友都能耳熟能详了吧。好了，就让我们看看在本次设计中用到了那些与UI有光的方法吧。

天龙八部的UI
总结
因为是接口所以只提供了核心的管理方法，UI是个比较繁琐的模块，一般都是配合脚本一起使用，CEGUI自己就集成了脚本绑定，有了解的应该知道。在这里我不再多讲UI的什么知识，希望大家看一下注释的每条方法的用处。UI模块有单独的一个库vgui（微gui）来控制，咱们到时候再详细探讨这里面的问题。下节讲的是声音模块。
