Unity - 在游戏对象实例化后重绘/重绘场景

Unity： 5.1.1f

语言： c#

当我在资产/编辑器/文件中实例化游戏对象时，在我选择另一个场景的游戏对象之前，它不会出现在场景中。

我尝试调用一些方法，例如：

SceneView.RepaintAll();
HandleUtility.Repaint();

但他们看起来都没有工作。这就是我生成对象的方式：

public class PrefabEditor: Editor {
    void OnSceneGUI() {
        GameObject prefabInstance = Instantiate(prefab) as GameObject;
        // assign him an icon label
        Texture2D tex = EditorGUIUtility.IconContent("sv_label_0").image as Texture2D;
        Type editorGUIUtilityType = typeof(EditorGUIUtility);
        BindingFlags bindingFlags = BindingFlags.InvokeMethod | BindingFlags.Static | BindingFlags.NonPublic;
        object[] args = new object[] {
            prefabInstance, tex
        };
        editorGUIUtilityType.InvokeMember("SetIconForObject", bindingFlags, null, null, args);
        EditorUtility.SetDirty(prefabInstance);
    }
}

GameObject prefabInstance = Instantiate(prefab) as GameObject;

GameObject prefabInstance = (GameObject) PrefabUtility.InstantiatePrefab(prefab);

SceneView.lastActiveSceneView.Repaint();
