在游戏中的交互过程中输入是一个必不可少的过程，比如登陆的时候需要用户输入用户名与密码，就算是单机游戏很多时候也要求用户输入一个用户名作为存档的依据。网络游戏中没有了输入，只用鼠标来交互是不切实际的，因为用户总会为单一的操作而觉得厌烦。资源提供系统，是将游戏中各种的资源加载到内存中以供使用，比如说一张图片，一张数据表等等。在cegui和ogre中都自己封装了输入与资源管理的类，本次设计中自然是在它基础上扩展封装。那么，就让我们看看这两块提供了哪些方法吧。

总结
客户端由于是基于windows开发的，所以依赖了许多与之相关的API，如果有疑惑可以提出或查询msdn资料手册。在这里由于时间关系，也不多详细讲解了，这一部分大家只要了解一下两个模块提供的方法就行。比如资源模块的只有两个API：加载与释放，而输入模块有捕获以及按键的状态。下节讲的是db模块，前端比较重要的文件数据处理，希望大家不要错过这节，因为配置的数据都是由此模块提供。
