Hey Hey. Testing out the compatibility of my asset with the soon to be released 2018.3. Sadly, it is broken. Here's where it falls down: Code (CSharp): var hierarchyWindowType = Assembly.GetAssembly(typeof(Editor)).GetType("UnityEditor.SceneHierarchyWindow") var createContextMenuMethod = hierarchyWindowType.GetMethod("CreateGameObjectContextClick", BindingFlags.NonPublic | BindingFlags.Instance); Debug.Log(createContextMenuMethod!=null); The debug line is just in there to pinpoint the problem. in 2018.2 ... the Debug return 'True', meaning the method has been found. in 2018.3 ... the Debug returns 'False' the method IS null I downloaded the UnityCsReference and it appears that that IS the still the name of the Method... What's the issue? Change BindingFlags, perhaps? Thanks for any insight.
