Unity3d 使用[CaneditMultipleObject]在gui中编辑多个对象

我已经创建了一个unity编辑器类，我想在其中选择我的瓷砖并向其添加墙。它适用于单选，但我不能适用于多选。我发现

[CaneditMultipleObject]

但单凭这一点是无济于事的。以下是编辑器脚本：

#if UNITY_EDITOR
using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(TileMorpherMonoBehaviour))] 
[CanEditMultipleObjects]
public class TileMorpher : Editor {

public override void OnInspectorGUI() {
    TileControl tileControl = (target as TileMorpherMonoBehaviour).gameObject.GetComponent<TileControl> ();

    if (GUILayout.Button("Add wall")) {
        tileControl.addWall ();
    }
    if (GUILayout.Button("Remove wall")) {
        tileControl.removeWall ();
    }
}

}
#endif

解决了。目标是关键

for(int i = 0; i < targets.Length; i++) {
    (target as SomeClass).gameObject.GetComponent<TileControl> ().addWall();
}
