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。
