D3D游戏编程系列（一）：DXLib的介绍

在上面的demo里面，我们使用了CDXListBox，CDXEdit这两个DXLib内部的控件，以及CDXMyButton这个控件，该控件也是继承DXLib内部的CDXButton控件。有兴趣的朋友可以试试这些控件，有什么建议也可以跟我提出来，我会不断改善的。

还有一点SetDrawDelay函数是设置DX程序的fps值，这里设置的是1000/20，也就是50。SetFps函数是设置fps的值是否显示在程序的左上角。下面我列出所有的DXLib的类，让大家一目了然：

CDXBaseMesh：网格的基类，是CDXEntity里的Mesh存储对象

CDXButton：Button控件

CDXCamera：第一人称Camera视角

CDXControl：控件的基类

CDXEdit：Edit控件

CDXEntity：实体类，主要作用于八叉树，用于存放每个Mesh对象

CDXHelper：Help帮助函数，可以做一些快速检测等操作

CDXLand：基于灰度图的地形渲染类

CDXListBox：Listbox控件

CDXLua：Lua脚本操作类

CDXMesh：网格操作类

CDXMutiplyStatic: 多行Static控件

CDXOctNode:八叉树渲染

CDXParticle:粒子渲染

CDXShader: Shader渲染

CDXSkinMesh: 骨骼动画操作类

CDXSky: 天空盒

CDXStatic: Static控件

CDXThirdCamera: 第三人称Camera视角

CDXWindow: DX窗体类，DX的创建，渲染，释放等

CDXXFile: 静态X文件渲染类

文章有不足之处，还望大家多多指正。
