D3DX10CreateEffectFromFile问题

Question

我在加载效果文件时遇到问题。我对D3DX10CreateEffectFromFile（）的调用与S_OK一起传递，但是函数调用后传入的ID3D10Effect * I仍然为null。这是我的来源（我一直在调试，所以有注释掉的东西，但相关的代码仍然在执行）。

HRESULT hResult;
void fxMgr::LoadEffectFile( char* fxFileName,
                            char* techniqueName,
                            ID3D10Effect* pEffect,
                    dgInputLayoutType layoutType)
{
/*if (L"fx"!=GetFileExtension(fxFileName))
{
    pEffect=NULL;
    throw dgGameError(L"Could not load specified shader!");
    return;
} 
*/    
if (NULL==fxFileName)
{
    pEffect=NULL;
    m_pCurEffect=NULL;
    m_pCurEffectTechnique=NULL;
    m_pCurPass=NULL;
}
        return;
HRESULT r = 0;

    DWORD shaderFlags = 0;//D3D10_SHADER_ENABLE_STRICTNESS;


/* #if defined( DEBUG ) || defined( _DEBUG )
                // Turn on extra debug info when in debug config
                shaderFlags |= D3D10_SHADER_DEBUG;
    #endif
    */
        ID3D10Blob* pErrors = NULL;
    // Create the effect
    r = D3DX10CreateEffectFromFileA(fxFileName , NULL, NULL, "fx_4_0", shaderFlags, 0, 
        Graphics()->GetDevice(), NULL, NULL, &pEffect, &pErrors, NULL);
        if(pErrors)
    {
        //MessageBoxA(0, (char*)pErrors->GetBufferPointer(),0, 0);
        SafeRelease(pErrors);
    }
    hResult=r;
    /*if(FAILED(r))
    {
        pEffect=NULL;
        return;
    }*/
    m_pCurEffect=pEffect;
    m_pCurEffectTechnique=pEffect->GetTechniqueByName(techniqueName);
    m_pCurPass=m_pCurEffectTechnique->GetPassByIndex(0);
        if (layoutArray[layoutType]==NULL)
    {

复制/粘贴有点破坏了空白，对不起！在此先感谢您的帮助！这个让我准备将视觉工作室刻录到光盘上，这样我就可以把它扔出窗外了......

您应该为Direct3D 10设备启用调试，然后查找任何相关输出。

此外，您应该检查所有HRESULT值是否失败......

请注意，如果您转移到Direct3D 11，那么您将拥有效果11的完整源代码，因为它位于CodePlex而不是操作系统的一部分。
