ID3DX11EffectPass GetDesc 访问冲突
ID3DX11EffectPass GetDesc Access Violation
您好，我刚刚了解了使用 DirectX 11 进行 3D 游戏编程的简介，我正在尝试让 BoxDemo 代码正常工作，但是我在效果方面遇到了麻烦。
基本上编译的着色器部分可以工作，甚至效果的创建也可以，但是当涉及到从效果通道获取描述时，我收到访问冲突错误，我已经尝试并在线研究但找不到任何帮助这件事。
请注意我有最新版本的 effects11.
这是效果图：

您已注释掉所有错误检查，因此 D3DX11CreateEffectFromMemory 可能返回失败。如果一个函数 returns 一个 HRESULT，你必须在运行时检查它，否则你会错过潜在的错误。这意味着使用 FAILED 宏、SUCCEEDED 宏或 ThrowIfFailed helper on every function that returns an HRESULT. See MSDN.
由于您正在使用 Effects for Direct3D 11 库，因此您应该从 GitHub. If you are using VS 2013 or VS 2015 for a Windows desktop app, you can also get it from NuGet 中获取最新版本。
您还应该阅读 this post which has some additional notes about the Introduction to 3D Game Programming with DirectX 11 book. It's a good book, but unfortunately it was published just before the DirectX development story was changed rather radically with the deprecation of the DirectX SDK. See MSDN。
You should also take a look at the DirectX Tool Kit tutorials, particularly the material on ComPtr.
好的，最后是最终代码

您好，我刚刚了解了使用 DirectX 11 进行 3D 游戏编程的简介，我正在尝试让 BoxDemo 代码正常工作，但是我在效果方面遇到了麻烦。 基本上编译的着色器部分可以工作，甚至效果的创建也可以，但是当涉及到从效果通道获取描述时，我收到访问冲突错误，我已经尝试并在线研究但找不到任何帮助这件事。 请注意我有最新版本的 effects11.

您已注释掉所有错误检查，因此 D3DX11CreateEffectFromMemory 可能返回失败。如果一个函数 returns 一个 HRESULT，你必须在运行时检查它，否则你会错过潜在的错误。这意味着使用 FAILED 宏、SUCCEEDED 宏或 ThrowIfFailed helper on every function that returns an HRESULT. See MSDN.
由于您正在使用 Effects for Direct3D 11 库，因此您应该从 GitHub. If you are using VS 2013 or VS 2015 for a Windows desktop app, you can also get it from NuGet 中获取最新版本。
您还应该阅读 this post which has some additional notes about the Introduction to 3D Game Programming with DirectX 11 book. It's a good book, but unfortunately it was published just before the DirectX development story was changed rather radically with the deprecation of the DirectX SDK. See MSDN。
You should also take a look at the DirectX Tool Kit tutorials, particularly the material on ComPtr.
好的，最后是最终代码
