DirectX游戏编程（一）：创建一个Direct3D程序

一、环境

Visual Studio 2012，DirectX SDK (June 2010)

二、准备

1.环境变量（如没有配置请添加）

变量名：DXSDK_DIR

变量值：D:\Software\Program\Microsoft DirectX SDK (June 2010)

这里D:\Software\Program\Microsoft DirectX SDK (June 2010)是我的DirectX安装目录，视情况修改即可

三、步骤

1.打开VS2012，创建一个空的Win32 Project

这里的项目名称（Name）可以自定义，项目位置（Location）可能不同，不过没关系，可以不用修改

点击OK，然后点击Next，勾选Empty Project

点击Finish，完成项目创建。

2.打开项目属性（Properites），配置项目的DirectX环境

主要需修改的项：Configuration Properites->VC++ Directories，Configuration Properites->Linker->General，Configuration Properites->Linker->Input

VC++ Directories：（注意后面的分号）

Include Directories项中添加$(DXSDK_DIR)\Include;

Library Directories项中添加$(DXSDK_DIR)\Lib\x86;

Linker->Input：添加以下三个lib文件d3d9.lib  d3dx9.lib Winmm.lib，添加时注意用分号隔开，如下：

d3d9.lib;d3dx9.lib;Winmm.lib;

Linker->General：AdditionalLibrary Directories项中添加$(DXSDK_DIR)\Lib\x86 （可以不加分号）

点击确定应用以上更改。

3.打开Source.cpp，复制以下代码：

 #include <d3dx9.h>
 IDirect3DDevice9* Device=;
 LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
 {
     switch(msg)
     {
     case WM_DESTROY:PostQuitMessage();break;
     case WM_KEYDOWN:
         if(wParam==VK_ESCAPE)DestroyWindow(hwnd);break;
     }
     return DefWindowProcW(hwnd,msg,wParam,lParam);
 }
 bool Init(HINSTANCE hInstance,int width,int height,bool windowed,D3DDEVTYPE devType,IDirect3DDevice9** device)
 {
     WNDCLASSW wc;
     wc.cbClsExtra=;
     wc.cbWndExtra=;
     wc.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
     wc.hCursor=LoadCursorW(,IDC_ARROW);
     wc.hIcon=LoadIconW(,IDI_APPLICATION);
     wc.hInstance=hInstance;
     wc.lpfnWndProc=(WNDPROC)WndProc;
     wc.lpszClassName=L"Direct3D";
     wc.lpszMenuName=;
     wc.style=CS_HREDRAW|CS_VREDRAW;
     if(!RegisterClassW(&wc))
     {
         MessageBoxW(,L"Register Failed",,);
         return false;
     }

     HWND hwnd=;
     hwnd=CreateWindowW(L"Direct3D",L"Direct3D",WS_OVERLAPPEDWINDOW,,,width,height,,,hInstance,);
     if(!hwnd)
     {
         MessageBoxW(,L"CreateWindow Failed",,);
         return false;
     }
     ShowWindow(hwnd,SW_SHOW);
     UpdateWindow(hwnd);

     HRESULT hr;
     IDirect3D9* d3d9;
     d3d9=Direct3DCreate9(D3D_SDK_VERSION);

     int vp=;
     D3DCAPS9 caps;
     d3d9->GetDeviceCaps(D3DADAPTER_DEFAULT,devType,&caps);
     if(caps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT)
         vp=D3DCREATE_HARDWARE_VERTEXPROCESSING;
     else vp=D3DCREATE_SOFTWARE_VERTEXPROCESSING;

     D3DPRESENT_PARAMETERS d3dapp;
     d3dapp.AutoDepthStencilFormat=D3DFMT_D24S8;
     d3dapp.BackBufferCount=;
     d3dapp.BackBufferFormat=D3DFMT_A8R8G8B8;
     d3dapp.BackBufferHeight=height;
     d3dapp.BackBufferWidth=width;
     d3dapp.EnableAutoDepthStencil=true;
     d3dapp.Flags=;
     d3dapp.FullScreen_RefreshRateInHz=D3DPRESENT_RATE_DEFAULT;
     d3dapp.hDeviceWindow=hwnd;
     d3dapp.MultiSampleQuality=;
     d3dapp.MultiSampleType=D3DMULTISAMPLE_NONE;
     d3dapp.PresentationInterval=D3DPRESENT_INTERVAL_IMMEDIATE;
     d3dapp.SwapEffect=D3DSWAPEFFECT_DISCARD;
     d3dapp.Windowed=windowed;
     hr=d3d9->CreateDevice(D3DADAPTER_DEFAULT,devType,hwnd,vp,&d3dapp,device);
     if(FAILED(hr))
     {
         MessageBoxW(,L"CreateDevice Failed",,);
         d3d9->Release();
         return false;
     }
     d3d9->Release();
     return true;
 }
 int EnterMsgLoop(bool (*ptr_display)(float TimeDelta))
 {
     MSG msg;
     ZeroMemory(&msg,sizeof(MSG));
     float LastTime=(float)GetCurrentTime();
     while(msg.message!=WM_QUIT)
     {
         if(PeekMessageW(&msg,,,,PM_REMOVE))
         {
             TranslateMessage(&msg);
             DispatchMessageW(&msg);
         }
         else
         {
             float CurTime=(float)GetCurrentTime();
             float TimeDelta=(float)(CurTime-LastTime)*0.001f;
             ptr_display(TimeDelta);
             LastTime=CurTime;
         }
     }
     return msg.wParam;
 }
 bool Setup()
 {
     return true;
 }
 void Cleanup()
 {

 }
 bool Display(float TimeDelta)
 {
     if(Device)
     {
         Device->Clear(,,D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER,0x00000000,1.0f,);
         Device->Present(,,,);
     }
     return true;
 }
 int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE prevInstance,PSTR cmdLine,int showCmd)
 {
     if(!Init(hInstance,,,true,D3DDEVTYPE_HAL,&Device))
         MessageBoxW(,L"Init Failed",,);
     if(!Setup())MessageBoxW(,L"Setup Failed",,);
     EnterMsgLoop(Display);
     Cleanup();
     Device->Release();
     return ;
 }

点击Local Windows Debugger编译项目，运行结果如下：

至此，第一个Direct3D程序已经完工。
