【问题描述】:
我是 DirectX 的菜鸟,在 Visual Studio 中运行 [this][1] 教程。在编译时,我遇到了这个错误:“错误 X3501:'main':找不到入口点。”现在一些谷歌搜索将我带到[this answer] [2],它说输入我的着色器文件的属性,将着色器类型和入口点设置为您想要的入口点。现在提供的答案很好,我不知道我的入口点应该是什么。起初我认为它应该是我实际调用D3DX11CompileFromFile() 的位置,它位于ColorShaderClass::InitializeShader 中,但我再次遇到错误X3501。做什么?
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;
}
和
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
}
编辑
正如 tsandy 所回答的,入口点是实际执行着色的函数。对于遵循本教程并使用与我对着色器文件相同的方案的任何人
ColorPS.hlsl 有入口点“ColorPixelShader”
ColorVS.hlsl 有入口点“ColorVertexShader”
