## 1.使用MenuItem添加菜单栏按钮 ##

![70][]

using UnityEditor;
    using UnityEngine;
    
    public class Tools  {
        [MenuItem ("Tools/test")]
        static void Test()
        {
            Debug.Log("Test");
        }
    }

## 2.关于MenuItem的路径设置和显示的先后顺序设置  ##

*  路径设置

using UnityEditor;
    using UnityEngine;
    
    public class Tools
    {
        [MenuItem("Tools/mytest/test1")]
        static void Test1()
        {
            Debug.Log("Test1");
        }
        [MenuItem("Tools/mytest/test2")]
        static void Test2()
        {
            Debug.Log("Test2");
        }
    }

![70 3][]

*  显示的先后顺序设置

using UnityEditor;
    using UnityEngine;
    
    public class Tools  {
        [MenuItem ("Tools/test1",false ,1)]
        static void Test1()
        {
            Debug.Log("Test1");
        }
        [MenuItem("Tools/test2",false ,2)]
        static void Test2()
        {
            Debug.Log("Test2");
        }
        [MenuItem("Tools/test3",false ,0)]
        static void Test3()
        {
            Debug.Log("Test3");
        }
    }

![70 4][]

可以看到Tools菜单栏下面的菜单按钮的顺序是test3-test1-test2，现在我想让test3和test1成为一组，即想在test1和test2之间插入一根横线，我们只需要让相邻的两个菜单按钮（这里是test1和test2）之间的priority相差11（或11以上）即可，如下：

using UnityEditor;
    using UnityEngine;
    
    public class Tools  {
        [MenuItem ("Tools/test1",false ,13)]
        static void Test1()
        {
            Debug.Log("Test1");
        }
        [MenuItem("Tools/test2",false ,2)]
        static void Test2()
        {
            Debug.Log("Test2");
        }
        [MenuItem("Tools/test3",false ,0)]
        static void Test3()
        {
            Debug.Log("Test3");
        }
    }

![70 5][]

*  GameObject菜单栏下显示test4，test5；Hierarchy下右键弹出框中显示test4：

using UnityEditor;
    using UnityEngine;
    
    public class Tools  {
        [MenuItem("GameObject/test4", false, 0)]
        static void Test4()
        {
            Debug.Log("Test4");
        }
        [MenuItem("GameObject/test5")]
        static void Test5()
        {
            Debug.Log("Test5");
        }
    }

![70 6][]![70 7][]

*  Assets菜单栏下显示mytest6,Project下右键弹出框显示mytest6:

using UnityEditor;
    using UnityEngine;
    
    public class Tools  {
        [MenuItem("Assets/mytest6")]
        static void Test6()
        {
            Debug.Log("Test6");
        }
    }

![70 8][] ![70 9][]

## 3.给组件的右键菜单栏添加按钮(需要加CONTEXT) ##

using UnityEditor;
    using UnityEngine;
    
    public class CubeEditor{
        [MenuItem ("CONTEXT/Cube/init")]//CONTEXT 组件名 按钮名
        static void Init()
        {
            Debug.Log("Init");
        }
    }

![70 10][]![70 11][]

## 4.关于MenuCommand的使用 ##

*  更改GameObject\_Cube的Cube组件里的speed为100

using UnityEditor;
    using UnityEngine;
    
    public class CubeEditor{
        [MenuItem ("CONTEXT/Cube/init")]
        static void Init(MenuCommand cmd)
        {
            Debug.Log(cmd.context.GetType().FullName);//Cube
            Cube cube = cmd.context as Cube;
            cube.speed = 100;
            Debug.Log("Init");
        }
    }

![70 12][]

*  更改GameObject\_Cube的Rigidbody组件里的Mass为10，Use Gravity取消勾选

using UnityEditor;
    using UnityEngine;
    
    public class CubeEditor{
        [MenuItem ("CONTEXT/Rigidbody/clear")]
        static void Init(MenuCommand cmd)
        {
            Rigidbody rg = cmd.context as Rigidbody;
            rg.mass = 10;
            rg.useGravity = false;
        }
    }

![70 13][]

## 5.使用Selection获取选择的游戏物体 ##

![70 14][]

using UnityEditor;
    using UnityEngine;
    
    public class Tools
    {
        [MenuItem("Tools/mytest")]
        static void Test()
        {
            Debug .Log(Selection.activeGameObject.name);//是我们选择的第一个游戏物体
            Debug.Log(Selection.objects.Length);
        }
    }

![70 15][]![70 16][]

## 6.编写可以撤销的删除操作（使用Undo.DestroyObjectImmediate（）方法） ##

using UnityEditor;
    using UnityEngine;
    
    public class Tools
    {
        [MenuItem("GameObject/my delete",false ,0)]
        static void Test()
        {
            foreach (Object o in Selection .objects)
            {
                Undo.DestroyObjectImmediate(o);//按Ctrl+Z可以撤销刚才的删除。推荐使用
                //GameObject.DestroyImmediate(o);按Ctrl+Z不可以撤销刚才的删除
            }
        }
    }

![70 17][]

## 7.给菜单项添加快捷键（%=ctrl， \#=shift， &=alt） ##

using UnityEditor;
    using UnityEngine;
    
    public class Tools
    {
        //%=ctrl #=shift &=alt
        [MenuItem("tools/test1 %q")]
        static void Test1()
        {
            Debug.Log("test1");
        }
        [MenuItem("tools/test2 _t")]
        static void Test2()
        {
            Debug.Log("test2");
        }
    }

![70 18][]

## 8.控制菜单项是否启用的功能（将MenuItem（）的第二个参数设为true） ##

using UnityEditor;
    using UnityEngine;
    
    public class Tools
    {
        [MenuItem("GameObject/my delete", true , 0)]
        static bool MyDeleteValidate()
        {
            if (Selection.objects.Length > 0)
                return true;
            else
                return false;
    
        }
    
        [MenuItem("GameObject/my delete", false, 0)]
        static void MyDelete()
        {
            foreach (Object o in Selection.objects)
            {
                Undo.DestroyObjectImmediate(o);//按Ctrl+Z可以撤销刚才的删除。推荐使用
                //GameObject.DestroyImmediate(o);按Ctrl+Z不可以撤销刚才的删除
            }
        }
    }

![70 19][]              ![70 20][]

## 9.关于ContextMenu和ContextMenuItem的使用 ##

*  ContextMenu（需要UnityEditor命名空间）

using UnityEditor;
    using UnityEngine;
    
    public class Cube : MonoBehaviour {
        public float speed;
    
        [ContextMenu("setSpeed")]
        void Init(MenuCommand cmd)
        {
            speed = 200;
        }
    }

![70 21][]

*  ContextMenuItem（不需要UnityEditor命名空间）

using UnityEngine;
    
    public class Cube : MonoBehaviour {
        [ContextMenuItem("AddSpeed","AddSpeed")]
        public float speed;
    
        void AddSpeed()
        {
            speed += 10;
        }
    }

![70 22][]

## 10.创建对话框 ##

using UnityEditor;
    
    public class EnemyChange : ScriptableWizard  {
    
        [MenuItem("myTools/CreateWizard")]
        static void CreateWizard()
        {
            DisplayWizard<EnemyChange>("统一修改敌人","修改");
        }
    }

![70 23][] ![70 24][]

点击myTools-CreateWizard，弹出“统一修改敌人”对话框：

![70 25][]

## 11.兼容按钮点击统一修改字段 ##

using UnityEngine;
    using UnityEditor;
    
    public class EnemyChange : ScriptableWizard  {
    
        [MenuItem("myTools/CreateWizard")]
        static void CreateWizard()
        {
            DisplayWizard<EnemyChange>("统一修改敌人","修改");
        }
        public int changeSpeed = 10;
    
        private void OnWizardCreate()//检测“修改”按钮的触发
        {
            Debug.Log("click");
            GameObject[] gos = Selection.gameObjects;
            foreach (GameObject go in gos)
            {
                gameobject_hp hp = go.GetComponent<gameobject_hp>();
                Undo.RecordObject(hp, "撤销更改");//按CTRL+Z可以返回上一步
                hp.Hp += 10;
            }
        }
    }

同时选中GameObjective-Cube和GameObjective-Sphere，点击【myTools】-【CreateWizard】-【修改】后，我们会发现它们的共同组件GameObjective-hp里的Hp属性从100变成了110。此时若再按Ctrl+z，则会从110变成100：

## 12.显示提示框的帮助信息和错误信息 ##

using UnityEngine;
    using UnityEditor;
    
    public class EnemyChange : ScriptableWizard  {
    
        [MenuItem("myTools/CreateWizard")]
        static void CreateWizard()
        {
            DisplayWizard<EnemyChange>("统一修改敌人","修改");
        }
        public int changeSpeed = 10;
    
        private void OnWizardCreate()//检测“修改”按钮的触发
        {
            GameObject[] gos = Selection.gameObjects;
            foreach (GameObject go in gos)
            {
                gameobject_hp hp = go.GetComponent<gameobject_hp>();
                Undo.RecordObject(hp, "撤销更改");
                hp.Hp += 10;
            }
        }
    
        private void OnWizardUpdate()//弹出对话框和修改对话框中的属性字段时会被调用
        {
            errorString = null;
            helpString = null;
            if(Selection.gameObjects .Length > 0)
            {
                helpString = "您当前选择了" + Selection.gameObjects.Length + "物体";
            }else
            {
                errorString = "请至少选择一个物体";
            }
        }
        private void OnSelectionChange()
        {
            OnWizardUpdate();
        }
    }

## 13.创建OtherButton按钮并监听按钮点击(OnWizardOtherButton()) ##

![70 28][]

## 14.使用ShowNotification显示提示信息(ShowNotification()) ##

using UnityEngine;
    using UnityEditor;
    
    public class EnemyChange : ScriptableWizard  {
    
        [MenuItem("myTools/CreateWizard")]
        static void CreateWizard()
        {
            DisplayWizard<EnemyChange>("统一修改敌人","修改并关闭","修改");
        }
        public int changeSpeed = 10;
    
        private void OnWizardCreate()//检测“修改并关闭”按钮的触发
        {
            GameObject[] gos = Selection.gameObjects;
            foreach (GameObject go in gos)
            {
                gameobject_hp hp = go.GetComponent<gameobject_hp>();
                Undo.RecordObject(hp, "撤销更改");
                hp.Hp += 10;
    
                ShowNotification(new GUIContent(Selection.gameObjects.Length + "个游戏物体的值被修改了"));
            }
        }
        private void OnWizardOtherButton()//检测“修改”按钮的触发
        {
            OnWizardCreate();
        }
    
        private void OnWizardUpdate()//弹出对话框和修改对话框中的属性字段时会被调用
        {
            errorString = null;
            helpString = null;
            if (Selection.gameObjects.Length > 0)
            {
                helpString = "您当前选择了" + Selection.gameObjects.Length + "物体";
            }
            else
