Question

已经为OpenGL ES和XNA编程了一段时间，我现在正将一些内容更新为DirectXTK用于XBOX One。可悲的是，我刚遇到另一个问题 - 即自定义着色器文件的集成。

特别是，我有以下顶点着色器：

cbuffer ModelViewProjectionConstantBuffer : register(b0)
{
    matrix model;
    matrix view;
    matrix projection;
};

struct VertexShaderInput
{
    float3 pos : POSITION;
};

struct PixelShaderInput
{
    float4 pos : SV_POSITION;
};

PixelShaderInput main(VertexShaderInput input)
{
    PixelShaderInput output;
    float4 pos = float4(input.pos, 1.0f);

    pos = mul(pos, model);
    pos = mul(pos, view);
    pos = mul(pos, projection);
    output.pos = pos;

    return output;
}

将其加载到IEffectFactory实现中可以正常工作。在第一步中，我使用LoadAsync加载已编译的hlsl文件：

void SUS3DApp1Main::SUSCreateDeviceResources()
{
    auto loadVSTask = DX::ReadDataAsync(L"SampleVertexShader.cso");
    auto loadPSTask = DX::ReadDataAsync(L"SamplePixelShader.cso");


    auto createVSTask = loadVSTask.then([this](const std::vector<byte>& fileData) {
        DX::ThrowIfFailed(
            m_deviceResources->GetD3DDevice()->CreateVertexShader(
                &fileData[0],
                fileData.size(),
                nullptr,
                &myVertexShader
            )
        );

        myVShaderCode = fileData.data();
        myVShaderCodeSize = fileData.size();
        myFlagVSUp = true;
    }); //VS hoch
    ...

然后将两个变量myVShaderCode和mVShaderCodeSize传递给iEffect的实际实现，iEffect使用它们如下：

void SUS3DApp1::SUSEffect::GetVertexShaderBytecode(void const ** pShaderByteCode, size_t * pByteCodeLength)
{
    (*pByteCodeLength) = myVShaderCodeSize;
    (*pShaderByteCode) = myVShaderCode;
}

可悲的是，这在运行时不起作用。而是，SUS3DApp1.exe中0x603520B5（ucrtbased.dll）上的未处理异常类型的错误：将无效参数传递给认为无效参数致命的函数。被扔了。调用堆栈如下所示：

>   SUS3DApp1.exe!DirectX::ThrowIfFailed(HRESULT hr) Line 48    C++
    SUS3DApp1.exe!CreateInputLayout(ID3D11Device * device, DirectX::IEffect * effect, ID3D11InputLayout * * pInputLayout, bool skinning) Line 202   C++
    SUS3DApp1.exe!DirectX::Model::CreateFromCMO(ID3D11Device * d3dDevice, const unsigned char * meshData, unsigned int dataSize, DirectX::IEffectFactory & fxFactory, bool ccw, bool pmalpha) Line 796  C++
    SUS3DApp1.exe!DirectX::Model::CreateFromCMO(ID3D11Device * d3dDevice, const wchar_t * szFileName, DirectX::IEffectFactory & fxFactory, bool ccw, bool pmalpha) Line 848 C++
    SUS3DApp1.exe!SUSModel::SUSModel(ID3D11Device * _dev, std::basic_string<char,std::char_traits<char>,std::allocator<char> > & resource, const unsigned char * _myVShaderCode, int _myVShaderCodeSize) Line 15    C++
    SUS3DApp1.exe!SUS3DApp1::SUS3DApp1Main::SetUpShaderDependentResources() Line 62 C++
    SUS3DApp1.exe!SUS3DApp1::SUS3DApp1Main::Render() Line 148   C++

想法，有人吗？我已经检查了GetVertexShaderBytecode中的成员变量的有效性......

更新：我现在更改了着色器，还加载了代码。奇怪的是，这部分代码现在通过了SUSCreateDeviceResources中的CreateInputLayout阶段： void SUS3DApp1Main :: SUSCreateDeviceResources（） { auto loadVSTask = DX :: ReadDataAsync（L“SampleVertexShader.cso”）; auto loadPSTask = DX :: ReadDataAsync（L“SamplePixelShader.cso”）;

    auto createVSTask = loadVSTask.then([this](const std::vector<byte>& fileData) {
        DX::ThrowIfFailed(
            m_deviceResources->GetD3DDevice()->CreateVertexShader(
                &fileData[0],
                fileData.size(),
                nullptr,
                &myVertexShader
            )
        );



        myVShaderCode = &fileData[0];
        myVShaderCodeSize = fileData.size();
        Microsoft::WRL::ComPtr<ID3D11InputLayout>       il;
        DX::ThrowIfFailed(
            m_deviceResources->GetD3DDevice()->CreateInputLayout(VertexPositionNormal::InputElements,
                VertexPositionNormal::InputElementCount,
                myVShaderCode, myVShaderCodeSize,
                &il)
        );
        myFlagVSUp = true;

    }); //VS hoch

然后在创建模型期间出现问题，它再次成为无效参数。这很奇怪，因为之前创作很好。可能是myVShaderCode的值丢失了吗？
