Is it possible to tween all objects within a panel?

[xikky]

I tried alpha tween on a panel but the tween is only applied to sprites that are direct children of the panel. Other sprites contained as children of Gameobjects, within the panel are not affected. Can I fix this?

Its very easy to build a tweener for panel alpha. (Took me 1 minute)

(Converted form the normal alpha tween script)

1. using UnityEngine;
2.  
3. /// <summary>
4. /// Tween the panels's alpha.
5. /// </summary>
6.  
7. [AddComponentMenu("NGUI/Tween/PanelAlpha")]
8. public class TweenPanelAlpha : UITweener
9. {
10.         public float from = 1f;
11.         public float to = 1f;
12.  
13.         Transform mTrans;
14.         UIPanel mPanel;
15.  
16.         /// <summary>
17.         /// Current alpha.
18.         /// </summary>
19.  
20.         public float alpha { get { return mPanel.alpha; } set { mPanel.alpha = value; } }
21.  
22.         /// <summary>
23.         /// Find all needed components.
24.         /// </summary>
25.  
26.         void Awake () { mPanel = GetComponentInChildren<UIPanel>(); }
27.  
28.         /// <summary>
29.         /// Interpolate and update the alpha.
30.         /// </summary>
31.  
32.         override protected void OnUpdate (float factor, bool isFinished) { alpha = Mathf.Lerp(from, to, factor); }
33.  
34.         /// <summary>
35.         /// Start the tweening operation.
36.         /// </summary>
37.  
38.         static public TweenAlpha Begin (GameObject go, float duration, float alpha)
39.         {
40.                 TweenAlpha comp = UITweener.Begin<TweenAlpha>(go, duration);
41.                 comp.from = comp.alpha;
42.                 comp.to = alpha;
43.                 return comp;
44.         }
45. }

Thanks! works perfect.

Built-in TweenAlpha works with panels.
