Unity uses MenuItem to modify the top menu bar

---

1. The desired effect

2. Create an Edit folder under Unity's Assets folder, and create a class that modifies MenuItem under this folder

3. Use [MenuItem("XXXX")] to create the top bar menu

using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEditor;//需要使用UnityEditor的类
using UnityEngine;

//Unity顶部菜单自定义修改
public class MyMenu
{

    //使用MenuItem来修改顶部菜单（%指ctrl|#指shift|&指alt）
    [MenuItem("MyMenu/Menu_01/Test_01 %#&1")]
    static void MyMenu1_Text01() {
        Debug.Log("你测试了菜单1");
    }
    [MenuItem("MyMenu/Menu_01/Test_02 %#&2")]
    static void MyMenu1_Text02()
    {
        Debug.Log("你测试了菜单2");
    }
    [MenuItem("MyMenu/Menu_02/Test_03 %#&3")]
    static void MyMenu2_Text01() {
        Debug.Log("你测试了菜单3");
    }
    [MenuItem("MyMenu/Menu_02/Test_04 %#&4")]
    static void MyMenu2_Text02() {
        Debug.Log("你测试了菜单4");
    }
}
