direct3d - L“首先修复调用 CDXUTDialog::Init()。详情请参阅评论。”

Question

调用回调函数 DXUTCreateDevice() 后，DXUTgui.cpp 断言检查返回错误。断言说首先调用 CDXUTDialog::Init() 但我应该把它放在 WinMain() 哪里？

将您的 DXUT 客户端代码与EmptyProject和SimpleSample的内容进行比较——假设您使用的是来自GitHub的 DXUT11 。

典型的模式是创建一个全局变量 for CDXUTDialogResourceManager，然后在你得到回调之前调用CDXUTDialog::InitfromInitAppDXUTCreateDevice

int WINAPI wWinMain( _In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPWSTR lpCmdLine, _In_ int nCmdShow ) 
{ 
    // Enable run-time memory check for debug builds. 
#ifdef _DEBUG 
    _CrtSetDbgFlag( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF ); 
#endif 


    // DXUT will create and use the best device 
    // that is available on the system depending on which D3D callbacks are set below 


    // Set DXUT callbacks 
    DXUTSetCallbackMsgProc( MsgProc ); 
    DXUTSetCallbackKeyboard( OnKeyboard ); 
    DXUTSetCallbackFrameMove( OnFrameMove ); 
    DXUTSetCallbackDeviceChanging( ModifyDeviceSettings ); 


    DXUTSetCallbackD3D11DeviceAcceptable( IsD3D11DeviceAcceptable ); 
    DXUTSetCallbackD3D11DeviceCreated( OnD3D11CreateDevice ); 
    DXUTSetCallbackD3D11SwapChainResized( OnD3D11ResizedSwapChain ); 
    DXUTSetCallbackD3D11SwapChainReleasing( OnD3D11ReleasingSwapChain ); 
    DXUTSetCallbackD3D11DeviceDestroyed( OnD3D11DestroyDevice ); 
    DXUTSetCallbackD3D11FrameRender( OnD3D11FrameRender ); 

    InitApp();  <-- // THIS IS WHERE DXUT GUI WIDGETS GET INITIALIZED, BEFORE THE WINDOW OR DEVICE IS CREATED
    DXUTInit( true, true, nullptr ); // Parse the command line, show msgboxes on error, no extra command line params 
    DXUTSetCursorSettings( true, true ); 
    DXUTCreateWindow( L"SimpleSample11" ); 


    // Only require 10-level hardware, change to D3D_FEATURE_LEVEL_11_0 to require 11-class hardware 
    // Switch to D3D_FEATURE_LEVEL_9_x for 10level9 hardware 
    DXUTCreateDevice( D3D_FEATURE_LEVEL_10_0, true, 800, 600 ); 


    DXUTMainLoop(); // Enter into the DXUT render loop 


    return DXUTGetExitCode(); 
} 

不建议使用 DXUT 启动新项目。它实际上仅用于维护依赖于 DXUT 的现有代码，同时删除对 D3DX11 和其他旧版 DirectX SDK 内容的依赖。DXUT 的绝大多数功能对于大多数应用程序来说都是多余的。它也是越野车，实际上仅适用于样品。
