EditorWindow.OnDestroy 当销毁

// Simple editor script that separates slightly a mesh from its triangles.
//从三角形稍微分开网格
// and prints after closing the inspector how many times the user distortionated the mesh
//并在关闭检视面板后打印，用户变形网格多少次
// Note the mesh will be updated when you focus the scene view.
//注意，在场景视图获得焦点时，网格将被更新
