分享Unity3d中调用C++写的Kinect手势的dll，打包运行报错！
用C++写了个Kinect手势的dll给unity用，脚本是用C#写的，点Play运行没有问题，打包运行exe报错！求大神现身帮忙看看是什么原因哪，先跪谢了。。。。
error.log如下：

经过各种测试表明应该是Nui_Init函数初始化Kinect失败返回的HRESULT 谢谢几位帮忙 结贴了

C#可以和c联调的，项目属性-调试-启用非托管代码调试，可以跟一下，传进去的参数是否正确。
还有那个init函数的参数，把bool改为int，再试试

从log信息(0xc0000005)判断应该是Nui_Init函数初始化Kinect失败返回的HRESULT

经测试判断是dll中所有函数都调用失败~
但是在Unity3d中，Play运行没有问题，打包之后资源文件中也有dll，运行打包之后的exe，执行调用dll中方法的一些操作都无效了，这会是什么原因呢？
Assets目录如下：MyModel，MyScript，Plugins，Scene。打包之后，资源自动会放到和生成的exe文件同目录下的ProjectName_Data目录，在这个目录下有Managed，Mono，Plugins（dll存在），Resources4个文件夹，mainData，PlayerConnectionConfigFile，sharedassets0.assets3个文件。

是所有的函数调用都有问题，还是其中一部分？
贴个以前做过的转换样例，可以参考下
[DllImport("mydll", EntryPoint = "MyFunction", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]

C#脚本

还需要cpp文件吗？

Access Violation可能相关：
1. stdcall cdecl fastcall等函数调用约定不匹配。
2. dllimport转换时，C#和C++对应的类型不匹配
实在不行把api贴出来看看
