DX中沒有任何東西在渲染DX 11

Question

我的DX程序在C++中沒有渲染（使用PS_5_0和VS_5_0）。我檢查了所有返回HRESULT的DX函數，它們都返回S_OK，我也經歷了仔細的調試並查看所有內容，沒有任何內容爲空或未初始化。我甚至在這裏搜索了每一處，並且我沒有找到任何幫助我的帖子（嘗試了所有的解決方案，看看它們是否有效，沒有一個是。）我不知道爲什麼它不是渲染，所有的參數很好。

這裏是我的代碼初始化深度模板，設備上下文和設備。

//create the graphics device factory 
    result = CreateDXGIFactory(__uuidof(IDXGIFactory), (void**)&factory);

這裏是我的代碼，使模型（我確信所有頂點哪裏好）

float color[4]; 

    //set up the color to clear the buffer to 
    color[0] = red; 
    color[1] = green; 
    color[2] = blue; 
    color[3] = alpha; 

    //clear the back buffer 
    m_deviceContext->ClearRenderTargetView(m_renderTarget, color); 

    //clear the depth buffer 
    m_deviceContext->ClearDepthStencilView(m_depthStencilView, D3D11_CLEAR_DEPTH, 1.0f,0); 

unsigned int stride; 
    unsigned int offset; 

    //set the vertex buffer stride and offset 
    stride = sizeof(Vertex); 
    offset = 0; 

    //Set the vertex buffer to be active on the device context 
    deviceContext->IASetVertexBuffers(0, 1, &m_vertexBuffer, &stride, &offset); 

    //Set the index buffer to active in the input assembler so it can be renderered 
    deviceContext->IASetIndexBuffer(m_indexBuffer, DXGI_FORMAT_R32_UINT, 0); 

    //set the type of primitive topology to use for rendering 
    deviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST); 

//Set the vertex input layout 
    deviceContext->IASetInputLayout(m_layout); 

    //Set the vertex and pixel shaders that will be used to render this triangle. 
    deviceContext->VSSetShader(m_vertexShader, NULL, 0); 
    deviceContext->PSSetShader(m_pixelShader, NULL, 0); 

    //Set the sampler state in the pixel shader. 
    deviceContext->PSSetSamplers(0, 1, &m_sampleState); 

    //Render the model 
    deviceContext->DrawIndexed(indexCount, 0, 0); 

//present the back buffer to the screen now that rendering is complete 
    m_swapChain->Present(m_vsync, 0); 

有誰知道我可能是做錯了什麼？（PS我最這個程序在GitHub中的最新版本在這裏：https://github.com/JustinWeq/Test-Engine。它包含了所有的文件（包括模型和着色器文件，所以如果你需要查看它以獲取更多信息，你可以）

我想它出來了，這是我設置它時缺少的一些參數，我修好了d it，謝謝你試圖幫助我所有人。
