Hierarchy視圖中選擇一個(gè)游戲?qū)ο笠院笸ㄟ^右鍵可以打開一個(gè)unity默認(rèn)菜單，一般情況下都可以滿足我們，但是我想真對(duì)某些特殊的游戲?qū)ο蠖归_特殊的菜單。如下圖所示，比如這樣：

Unity3D研究院編輯器之重寫Hierarchy的右鍵菜單（二十二） - 雨松MOMO程序研究院 - 1

代碼：

using UnityEngine;
using UnityEditor;
using System.Collections;
 
public class MyHierarchyMenu
{
    [MenuItem("Window/Test/yusong")]
    static void Test()
    {
    }
 
    [MenuItem("Window/Test/momo")]
    static void Test1()
    {
    }
    [MenuItem("Window/Test/雨松/MOMO")]
    static void Test2()
    {
    }
 
 
    [InitializeOnLoadMethod]
     static void StartInitializeOnLoadMethod()
     {
         EditorApplication.hierarchyWindowItemOnGUI += OnHierarchyGUI;
     }
 
     static void OnHierarchyGUI(int instanceID, Rect selectionRect)
     {
         if (Event.current != null && selectionRect.Contains(Event.current.mousePosition)
             && Event.current.button == 1 && Event.current.type <= EventType.mouseUp)
         {
             GameObject selectedGameObject = EditorUtility.InstanceIDToObject(instanceID) as GameObject;
             //這里可以判斷selectedGameObject的條件
             if (selectedGameObject)
             {
                Vector2 mousePosition = Event.current.mousePosition;
 
                EditorUtility.DisplayPopupMenu(new Rect(mousePosition.x, mousePosition.y, 0, 0), "Window/Test",null);
                Event.current.Use();
             }          
         }
     }
 
}
