Multi-object editing

[eldee]

Hi, just curious if there are plans to update the editor scripts to use unity 3.5's CanEditMultipleObjects? There are a lot of times where I need to change a common property on several objects (such as the atlas, sprite, color, or depth) but need to do it individually. Just curious! Thanks!

Yeah it's on the list.

Bump.

Is there any quick fix for this? I'm pretty shaky on Editor modifying. I have dozens of Tween Alpha objects that need to get a lot of standard values and testing with mass-changes.

Cheers, keep up the great work.

I know you said you're shaky on Editor modifying, but I'd say it's worthwhile to learn a bit about it. You can make a simple EditorWindow that can iterate through all the currently selected objects and modify them. You can learn how to do it in probably an afternoon and once you have, it takes about 10 minutes to implement something. If you don't like having to select things, you can use a tag or create a helper script that can be searched for. For example, tag all your TweenAlphas with 'TAType1' or something and just search for the tag, or have a script with just a Type enum to search for.

Here's a rough example I made yesterday to find and change all UIPanels in the scene:

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using UnityEditor;
5. using UnityEngine;
6.  
7. public class ChangeAllPanels : EditorWindow
8. {
9.         #region Fields & Structs
10.  
11.         private PanelSettings panelSettings = new PanelSettings();
12.  
13.         private class PanelSettings
14.         {
15.                 public int renderQ = 3000;
16.                 public UIPanel.RenderQueue renderQSetting = UIPanel.RenderQueue.Automatic;
17.         }
18.  
19.         #endregion
20.  
21.         #region Functionality
22.  
23.         private void ApplyPanelSettings ()
24.         {
25.                 Debug.Log("Applying UIPanel Settings");
26.                 List<UIPanel> panels = GetAllObjectsInScene<UIPanel>();
27.  
28.                 foreach ( var p in panels )
29.                 {
30.                         Undo.RecordObject(p, "Apply Panel Settings");
31.  
32.                         p.startingRenderQueue = panelSettings.renderQ;
33.                         p.renderQueue = panelSettings.renderQSetting;
34.  
35.                         EditorUtility.SetDirty(p);
36.                 }
37.         }
38.  
39.         public static List<T> GetAllObjectsInScene<T> () where T : Component
40.         {
41.                 var compsInScene = Resources.FindObjectsOfTypeAll<T>().ToList();
42.  
43.                 for ( int i = compsInScene.Count-1; i >= 0; --i )
44.                 {
45.                         T comp = compsInScene[i];
46.  
47.                         if ( ( comp.hideFlags & HideFlags.NotEditable ) == HideFlags.NotEditable
48.                           || ( comp.hideFlags & HideFlags.HideAndDontSave ) == HideFlags.HideAndDontSave
49.                           || !String.IsNullOrEmpty(AssetDatabase.GetAssetPath(comp.transform.root.gameObject)) )
50.                                 compsInScene.RemoveAt(i);
51.                 }
52.  
53.                 return compsInScene;
54.         }
55.  
56.         #endregion
57.  
58.         #region GUI/Window Methods
59.  
60.         private void OnGUI ()
61.         {
62.                 PanelSettings ps = panelSettings;
63.                 ps.renderQ = EditorGUILayout.IntField("Render Q", ps.renderQ);
64.                 ps.renderQSetting = (UIPanel.RenderQueue) EditorGUILayout.EnumPopup("Render Q Setting", ps.renderQSetting);
65.  
66.                 if ( GUILayout.Button("Apply") )
67.                         ApplyPanelSettings();

Most NGUI elements are multi-editable. Some are not. Tweens aren't. I update them as I find them.
