Question

我正在学习DirectX，正在我的应用程序中初始化Direct3d，我的所有HRESULTS都返回S_OK，这是成功的返回代码，除了最后一个涉及交换链创建的代码，我已启用了调试层，因此我收到了警告错误输出日志显示'OurDevice'可能为0 ...（OurDevice是指向我的ID3D11Device的指针名称）..经过Microsoft Docs扫描并检查并重新检查所有我的代码很多小时后，我似乎无法发现问题所在有人知道吗？

如果同时启用DXGI debugging和使用D3D11_CREATE_DEVICE_DEBUG，则将在调试窗口中获得输出消息，告诉您导致错误代码失败的问题。

即使仅启用Direct3D 11调试，您仍然可以：

D3D11 ERROR: ID3D11Device::CreateTexture2D1: D3D11_RESOURCE_MISC_GDI_COMPATIBLE
requires a B8G8R8A8 format.
[ STATE_CREATION ERROR #103: CREATETEXTURE2D_INVALIDMISCFLAGS]

因此，您的问题非常简单且易于解决：将dxgi_format更改为DXGI_FORMAT_B8G8R8A8_UNORM

请参见Anatomy of Direct3D 11 Create Device和Direct3D Game Visual Studio templates
