我对DirectX不熟悉,在Visual Studio中运行[此教程][1]时遇到编译错误:"error X3501: 'main': entrypoint not found."。通过搜索,我找到了[这个答案][2],其中建议在我的着色器文件属性中设置着色器类型和入口点。尽管提供的解决方案非常好,但是我不知道我的入口点应该是什么。起初,我以为它应该是我实际调用的
我的文件如下:
使用名称的方法
D3DX11CompileFromFile()
函数,即在ColorShaderClass::InitializeShader
中,然而我又遇到了X3501错误。请问该怎么办?
我的文件如下:
ColorVS.hlsl
ColorPS.hlsl
使用名称的方法
bool ColorShaderClass::Initialize(ID3D11Device* device, HWND hwnd)
{
bool result;
// Initialize the vertex and pixel shaders.
result = InitializeShader(device, hwnd, L"ColorVS.hlsl", L"ColorPS.hlsl");
if (!result)
{
return false;
}
return true;
}
并且
bool ColorShaderClass::InitializeShader(ID3D11Device* device, HWND hwnd, WCHAR* vsFilename, WCHAR* psFilename)
{
HRESULT result;
ID3D10Blob* errorMessage;
ID3D10Blob* vertexShaderBuffer;
ID3D10Blob* pixelShaderBuffer;
D3D11_INPUT_ELEMENT_DESC polygonLayout[2];
unsigned int numElements;
D3D11_BUFFER_DESC matrixBufferDesc;
// Initialize the pointers this function will use to null.
errorMessage = 0;
vertexShaderBuffer = 0;
pixelShaderBuffer = 0;
// Compile the vertex shader code.
result = D3DX11CompileFromFile(vsFilename, NULL, NULL, "ColorVertexShader", "vs_5_0", D3D10_SHADER_ENABLE_STRICTNESS, 0, NULL,
&vertexShaderBuffer, &errorMessage, NULL);
if (FAILED(result))
{
// If the shader failed to compile it should have writen something to the error message.
if (errorMessage)
{
OutputShaderErrorMessage(errorMessage, hwnd, vsFilename);
}
// If there was nothing in the error message then it simply could not find the shader file itself.
else
{
MessageBox(hwnd, vsFilename, L"Missing Shader File", MB_OK);
}
return false;
}
// Compile the pixel shader code.
result = D3DX11CompileFromFile(psFilename, NULL, NULL, "ColorPixelShader", "ps_5_0", D3D10_SHADER_ENABLE_STRICTNESS, 0, NULL,
&pixelShaderBuffer, &errorMessage, NULL);
if (FAILED(result))
{
// If the shader failed to compile it should have writen something to the error message.
if (errorMessage)
{
OutputShaderErrorMessage(errorMessage, hwnd, psFilename);
}
// If there was nothing in the error message then it simply could not find the file itself.
else
{
MessageBox(hwnd, psFilename, L"Missing Shader File", MB_OK);
}
return false;
}
//more code
}

正如tsandy所回答的那样,入口点是实际执行着色的函数。对于那些遵循本教程并使用与我相同方案的人来说:
ColorPS.hlsl 的入口点为 "ColorPixelShader"
ColorVS.hlsl 的入口点为 "ColorVertexShader"
