Question

我是渲染API的新手，直到现在我一直都没事。我已经调试了一段时间来解决这个问题，但我无法弄清楚为什么这不起作用。所以我需要一些帮助。

我相信问题的根源在这里。

m_VertexShader->Release();

因为它没有返回HRESULT，所以我无法做到。

这是代码。

    #include "shader.h"

    ShaderProgram::ShaderProgram(Renderer& renderer, const char* vertShader, const char* pixShader)
    : m_Renderer(renderer), m_VertexShaderSource(vertShader), m_PixelShaderSource(pixShader)
    {
    Load();
    }

    ShaderProgram::~ShaderProgram()
    {
    m_VertexShader->Release();
    m_PixelShader->Release();
    m_InputLayout->Release();
    }

    void ShaderProgram::Load()
    {
    vector<char> vertSource = FileReader::read_file(m_VertexShaderSource);
    vector<char> fragSource = FileReader::read_file(m_PixelShaderSource);

    auto resultVert = m_Renderer.getDevice()->CreateVertexShader(vertSource.data(), vertSource.size(), nullptr, &m_VertexShader);
    auto resultFrag = m_Renderer.getDevice()->CreatePixelShader(fragSource.data(), fragSource.size(), nullptr, &m_PixelShader);

    if (resultVert != S_OK || resultFrag != S_OK)
    {
        MessageBox(nullptr, "Failed to create shader!", "Error", MB_OK);
        exit(0);
    }

    D3D11_INPUT_ELEMENT_DESC layout[]{
        { "POSITION", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 },
        { "COLOR", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, D3D11_APPEND_ALIGNED_ELEMENT, D3D11_INPUT_PER_VERTEX_DATA, 0 }
    };

    auto result = m_Renderer.getDevice()->CreateInputLayout(layout, 2, vertSource.data(), vertSource.size(), &m_InputLayout);
    if (result != S_OK)
    {
        MessageBox(nullptr, "Could not create the input layout!", "Error", MB_OK);
        exit(0);
    }

这是我的渲染类。顺便说一下，我刚才刚刚添加了模板和深度测试，可能需要解决这个问题。

    #include "renderer.h"

    Renderer::Renderer(Window& window)
    {
    createDevice(window);
    createRenderTarget();
    createDepthStencil();
    }

    Renderer::~Renderer()
    {
    m_SwapChain->Release();
    m_Device->Release();
    m_DeviceContex->Release();
    m_RenderTargetView->Release();
    m_DepthStencilView->Release();
    }

    void Renderer::createDevice(Window& window)
    {
    DXGI_SWAP_CHAIN_DESC swapChain = { 0 };
    swapChain.BufferCount = 1;
    swapChain.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
    swapChain.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
    swapChain.OutputWindow = window.getHandle();
    swapChain.SampleDesc.Count = 1;
    swapChain.Windowed = true;

    auto result = D3D11CreateDeviceAndSwapChain(nullptr, D3D_DRIVER_TYPE_HARDWARE, nullptr, 0, nullptr,
        0, D3D11_SDK_VERSION, &swapChain, &m_SwapChain, &m_Device, nullptr, &m_DeviceContex);

    if (result != S_OK)
    {
        MessageBox(nullptr, "Problem with creating DX11!", "Error", MB_OK);
        exit(0);
    }
}

    void Renderer::createDepthStencil()
    {
    D3D11_TEXTURE2D_DESC depthStencilDesc;

    depthStencilDesc.Width = m_BackBuffer.Width;
    depthStencilDesc.Height = m_BackBuffer.Height;
    depthStencilDesc.MipLevels = 1;
    depthStencilDesc.ArraySize = 1;
    depthStencilDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;
    depthStencilDesc.SampleDesc.Count = 1;
    depthStencilDesc.SampleDesc.Quality = 0;
    depthStencilDesc.Usage = D3D11_USAGE_DEFAULT;
    depthStencilDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL;
    depthStencilDesc.CPUAccessFlags = 0;
    depthStencilDesc.MiscFlags = 0;

    m_Device->CreateTexture2D(&depthStencilDesc, nullptr, &m_DepthStencilBuffer);
    m_Device->CreateDepthStencilView(m_DepthStencilBuffer, nullptr, &m_DepthStencilView);
    m_DepthStencilBuffer->Release();
}

    void Renderer::createRenderTarget()
    {
    ID3D11Texture2D* backBuffer;
    auto result = m_SwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (void**)&backBuffer);
    if (result != S_OK)
    {
        MessageBox(nullptr, "Failed to get the swap chain buffer!", "Error", MB_OK);
        exit(0);
    }
    m_Device->CreateRenderTargetView(backBuffer, nullptr, &m_RenderTargetView);

    backBuffer->GetDesc(&m_BackBuffer);
    backBuffer->Release();
   }

    void Renderer::beginFrame()
    {
    m_DeviceContex->OMSetRenderTargets(1, &m_RenderTargetView, m_DepthStencilView);

    auto viewport = CD3D11_VIEWPORT(0.0f, 0.0f, (float) m_BackBuffer.Width, (float) m_BackBuffer.Height);
    viewport.MinDepth = 0.0f;
    viewport.MaxDepth = 1.0f;
    m_DeviceContex->RSSetViewports(1, &viewport);

    float clearColor[] = { 0.25f, 0.75f, 0.8f, 1.0f };
    m_DeviceContex->ClearRenderTargetView(m_RenderTargetView, clearColor);
    m_DeviceContex->ClearDepthStencilView(m_DepthStencilView, D3D11_CLEAR_DEPTH | D3D11_CLEAR_STENCIL, 1.0f, 0);
    }

//Swaps the buffer!

    void Renderer::endFrame()   
    {
       m_SwapChain->Present(1, 0);
    }

}

在非调试模式下运行时是否会出现相同的错误？使用有限的信息，您看起来似乎没有找到您的调试符号表。如果它在非调试模式下完全正常，那么它将通过文档进行筛选以找出如何加载符号表。答案不是很多，但希望它可能会有所帮助

你真的应该转向使用Microsoft::WRL::ComPtr。使用原始指针，您可能会调用Release太少或太多次，这就是这里发生的事情。请参阅this page。

它会删除愚蠢的事情，就像你释放它时保持指向m_DepthStencilView的悬挂指针。您根本不需要将其变为成员变量，因为您只使用它来创建m_DepthStencilView。

#include <wrl/client.h>

using Microsoft::WRL::ComPtr;

...

ComPtr<ID3D11Texture2D> depthStencil;
m_Device->CreateTexture2D(&depthStencilDesc, nullptr, &depthStencil);
m_Device->CreateDepthStencilView(depthStencil.Get(), nullptr, &m_DepthStencilView);

查看Direct3D 11游戏Visual Studio模板，特别是DeviceResources.h / DeviceResources.cpp的实现。

为什么我收到的信息不可用，没有加载符号d3d11.dll错误
