D3D11 创建着色器：编码的顶点着色器大小与指定大小不匹配

Question

我正在使用 DirectX 11 开发游戏引擎，但在让着色器正确编码时遇到问题。我正在将着色器预编译为 .csh 文件并使用字节代码创建着色器。

我在尝试创建任何着色器时遇到此错误，但对于此示例，我将使用我的 PassThrough 顶点着色器。

D3D11 ERROR: ID3D11Device::CreateVertexShader: Encoded Vertex Shader size doesn't match specified size. [ STATE_CREATION ERROR #166: CREATEVERTEXSHADER_INVALIDSHADERBYTECODE]

着色器：

#include "../VertexLayouts.hlsli"
// structs in included file
struct PASS_THROUGH_VS
{
    float3 pos : POSITION;
    float2 texCoord : TEXCOORD;
};

struct PASS_THROUGH_PS
{
    float4 pos : SV_POSITION;
    float2 texCoord : TEXCOORD;
};


PASS_THROUGH_PS main( PASS_THROUGH_VS input )
{
    PASS_THROUGH_PS output = (PASS_THROUGH_PS)(0);
    output.pos = float4(input.pos, 1);
    output.texCoord = input.texCoord;
    return output;
}

使用这些设置： PassThrough_PS properties

在Renderer.h

#include "Vertex Shaders\PassThrough_VS.csh"

在Renderer.cpp

HRESULT hrReturn;

    hrReturn = CreateVertexShader(&PassThrough_VS, sizeof(PassThrough_VS), Pass_Through_VS);
    if (FAILED(hrReturn)) {}
        //return hrReturn;

HRESULT CRenderer::CreateVertexShader(const void* ptrByteCode, SIZE_T szByteCodeLength, eVertexShaderType type)
{
    HRESULT hrReturn;
    tVertShader newShader = {};
    hrReturn = D3Device->CreateVertexShader(&ptrByteCode, szByteCodeLength, nullptr, &(newShader.m_id3dShader)); // WHERE ERROR OCCURS
    if (FAILED(hrReturn))
        return hrReturn;
    newShader.m_ptrByteCode = ptrByteCode;
    newShader.m_szByteCodeLength = szByteCodeLength;
    D3VertexShaders[type] = newShader;
    return hrReturn;
}

Answer 1

问题是您传递的是指向指针的指针，因此您实际上并未将着色器 blob 数据传递给 Direct3D。

HRESULT CRenderer::CreateVertexShader(const void* ptrByteCode, SIZE_T szByteCodeLength, eVertexShaderType type)
{
    HRESULT hrReturn;
    tVertShader newShader = {};
    hrReturn = D3Device->CreateVertexShader(&ptrByteCode, szByteCodeLength,
        nullptr, &(newShader.m_id3dShader));
    ...

正确的代码是：

HRESULT CRenderer::CreateVertexShader(const void* ptrByteCode, SIZE_T szByteCodeLength, eVertexShaderType type)
{
    HRESULT hrReturn;
    tVertShader newShader = {};
    hrReturn = D3Device->CreateVertexShader(ptrByteCode, szByteCodeLength,
        nullptr, &(newShader.m_id3dShader));
    ...

You should take a look at DirectX Tool Kit and the tutorials in particular.

您没有包含有关 tVertShader 类型的任何详细信息，但您很可能遇到引用计数问题。考虑使用 Microsoft::WRL::ComPtr 而不是原始指针来管理 Direct3D COM 对象的生命周期。参见 this article。
