I wanna to draw a menu. and here is the code, but i come across a problem when i hit Play,and i find the error is caused by this line of code below:GUI.Window(GlobalGUIWindowId._WND2_YXY..... ,and the error in the console window says:
InvalidOperationException: Hashtable.Enumerator: snapshot out of sync. System.Collections.Hashtable+Enumerator.FailFast () System.Collections.Hashtable+Enumerator.MoveNext () UnityEngine.GUI.EndWindows (UnityEngine.IDList idlist) (at C:/BuildAgent/work/f724c1acfee760b6/Runtime/ExportGenerated/Editor/GUI.cs:1225) UnityEngine.GUIUtility.EndGUI (Int32 doLayout, Int32 doWindows, UnityEngine.IDList idlist) (at C:/BuildAgent/work/f724c1acfee760b6/Runtime/ExportGenerated/Editor/GUIUtility.cs:359)
I have no idea how to debug it, may you help me. Thank you very much!
