Hi all,

I have an editor script that clones an existing GameObject then selects it in the hierarchy. I want to rename the GameObject immediately after selection, mimicing the F2 rename feature.

Any way to do this in code?

Thanks.

The script posted in the old answer no longer works in newer unity versions. Use this instead:

    using UnityEngine;
    using UnityEditor;
    using System.Reflection;
     
    public class ObjClone : EditorWindow
    {
     
        // Add menu named "My Window" to the Window menu
        [MenuItem("Window/ObjClone")]
        static void Init()
        {
            // Get existing open window or if none, make a new one:
            ObjClone window = (ObjClone)EditorWindow.GetWindow(typeof(ObjClone));
            window.Show();
        }
     
        GameObject g;
        GameObject clone;
        volatile bool triggerRename;
        private static double renameTime;
     
        void OnGUI()
        {
            g = (GameObject)EditorGUILayout.ObjectField(g, typeof(GameObject), true);
            if (GUILayout.Button("Clone"))
            {
                clone = Instantiate<GameObject>(g);
     
                EditorApplication.update += EngageRenameMode;
                renameTime = EditorApplication.timeSinceStartup + 0.4d;
                EditorApplication.ExecuteMenuItem("Window/General/Hierarchy");
                Selection.activeGameObject = clone;
            }
        }
     
        private void EngageRenameMode()
        {
            if (EditorApplication.timeSinceStartup >= renameTime)
            {
                EditorApplication.update -= EngageRenameMode;
                var e = new Event { keyCode = KeyCode.F2, type = EventType.KeyDown }; // or Event.KeyboardEvent("f2");
                EditorWindow.focusedWindow.SendEvent(e);
            }
        }
    }

Ok. Took me some time, but here you go:

using UnityEngine;
using UnityEditor;
using System.Reflection;

public class ObjClone : EditorWindow
{

    // Add menu named "My Window" to the Window menu
    [MenuItem("Window/ObjClone")]
    static void Init()
    {
        // Get existing open window or if none, make a new one:
        ObjClone window = (ObjClone)EditorWindow.GetWindow(typeof(ObjClone));
        window.Show();
    }

    GameObject g;
    GameObject clone;
    volatile bool triggerRename;
    private static double renameTime;

    void OnGUI()
    {
        g = (GameObject)EditorGUILayout.ObjectField(g, typeof(GameObject), true);
        if (GUILayout.Button("Clone"))
        {
            clone = Instantiate<GameObject>(g);

            EditorApplication.update += EngageRenameMode;
            renameTime = EditorApplication.timeSinceStartup + 0.4d;
            EditorApplication.ExecuteMenuItem("Window/Hierarchy");
            Selection.activeGameObject = clone;
        }
    }

    private void EngageRenameMode()
    {
        if (EditorApplication.timeSinceStartup >= renameTime)
        {
            EditorApplication.update -= EngageRenameMode;
            var type = typeof(EditorWindow).Assembly.GetType("UnityEditor.SceneHierarchyWindow");
            var hierarchyWindow = EditorWindow.GetWindow(type);
            var rename = type.GetMethod("RenameGO", BindingFlags.Instance | BindingFlags.NonPublic);
            rename.Invoke(hierarchyWindow, null);
        }
    }
}
