Visual Studio .CreateInputLayout 的东西

问题描述

InputLayout::InputLayout(Graphics& gfx,const std::vector<D3D11_INPUT_ELEMENT_DESC>&layout,ID3DBlob* pVertexByteCode) : pInputLayout(&layout)
{
    INFOMAN(gfx);

    GFX_THROW_INFO(GetDevice(gfx)->CreateInputLayout(
        layout.data(),(UINT)layout.size(),pVertexByteCode->GetBufferPointer(),pVertexByteCode->GetBufferSize(),pInputLayout.GetAddressOf()));
}

问题是在编译这段代码后我得到：

1>C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\winrt\wrl\client.h(252,45): error C2440: 'initializing': cannot convert from 'U *' to 'ID3D11InputLayout *'

1>            U=const std::vector<D3D11_INPUT_ELEMENT_DESC,std::allocator<D3D11_INPUT_ELEMENT_DESC>>
1>        ] (compiling source file InputLayout.cpp)

1>        ]

1>        ]

错误出现在 CreateInputLayout 的第一个参数处，在我看来是向量类型导致它（不知何故）所以我创建了一个数组，但它没有用

InputLayout::InputLayout(Graphics& gfx,ID3DBlob* pVertexByteCode) : pInputLayout(&layout)
{
    INFOMAN(gfx);
    const D3D11_INPUT_ELEMENT_DESC ied[] =
    {
        {"Position",0u,dxgi_FORMAT_R32G32B32_FLOAT,D3D11_INPUT_PER_VERTEX_DATA,0}
    };
    GFX_THROW_INFO(GetDevice(gfx)->CreateInputLayout(
        ied,pInputLayout.GetAddressOf()));
}

这会导致同样的错误。我很困惑，因为它在其他具有类似语法的文件中工作

wrl::ComPtr<ID3D11InputLayout> pInputLayout;
const D3D11_INPUT_ELEMENT_DESC ied[] = 
{ 
    {"Position",0},{"Color",dxgi_FORMAT_R8G8B8A8_UnorM,12u,0}
};
GFX_THROW_INFO(pDevice->CreateInputLayout(ied,(UINT)std::size(ied),pBlob->GetBufferPointer(),pBlob->GetBufferSize(),&pInputLayout));

注意：GetDevice(gfx) 返回 ID3D11Device*，它是主要的图形设备，而 pInputLayout（在之前的代码中）来自不同的类
