unity DestroyBuffer can only be called from the main thread

DestroyBuffer can only be called from the main thread.

Constructors and field initializers will be executed from the loading thread when loading a scene.

Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.

多线程时会产生这个错误

还有使用设备延迟或者卡住的时候也会产生这个错误（比如kinect造成）

另外调试的时候程序切换后台也有一定几率导致这个错误（可以试试user setting里面开后台运行）
