DirectX3D开发之开发第一个DirectX3D项目

标签：directx3d开发

    欢迎访问EasyLiu的博客!此博客为博主原创，未经允许不得转载！

    开发环境：WIN764+VS2013+DirectX SDK(June 2010)

     首先提供DirectX3D软件包下载地址：http://pan.baidu.com/s/16WItw。

    下载下来之后直接双击安装就行，默认安装目录为：C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)。

    下面就开始我们的第一个DirectX3D项目。

    1、新建一个空的win32应用程序，记住不是win32控制台应用程序，这两者是由区别的！

    2、项目完成以后，配置DirectX开发环境：

    选择“项目”--》“属性”，打开属性配置窗口如下所示：

    选择“VC++目录”，把DirectX  SDK 的“包含目录（Include）”以及"库目录（Lib）"包含进去，分别为：

   C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include

    C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86，虽然我的系统是win764位，但是当我的引用库目录改为x64时候会报错，改为x86就不会报错，不知道      怎么回事！

    点击确定退出属性配置窗口。

   新建文件：main.cpp,在文件开头加上引用库：

  #pragma comment(lib, "d3d9.lib")
  #pragma comment(lib, "d3dx9.lib")

   打开帮助文档：C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Documentation\DirectX9\directx_sdk.chm，切换到如下目录：

  Toutorial 1就详细讲了怎么创建一个DirectX 3D项目，虽然是英文但是应该不难看，并且Toutorial  1有对应的Sample 工程，位于如下目录：

  C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\\Samples\C++\Direct3D\Tutorials\Tut01_CreateDevice，这里包含了一个完整的工程，我们只需把其代码复制到  我们的文件main.cpp里面就行了！

 下面是源代码：应该不难看懂，纯粹使用win32 API开发，包括设计窗口、注册窗口、创建窗口等一系列过程，如果对win32开发还不是很懂的同学可以先看一下孙鑫的VC++深入详解，讲得很详细，通俗易懂！

总结：帮助文档还是挺好的，写的很详细，还有助于锻炼我们的英文水平！哈哈！
