Is MenuItem supported anymore?

I’m following a tutorial on creating scripts to add a menu item in the GameObject menu in the Editor toolbar. Looking up the API, however, doesn’t show the MenuItem class - the class the instructor is prompting viewers to use - except when searching the class up in the search engine on the API website.

Regardless, I tried following the tutorial along the way in another programming language (I was using C#; he used JavaScript). However, when I added the code necessary to add a MenuItem, the keyword wasn’t supported in editor I was using. Here’s what the editor shows:

Does this mean the MenuItem class is not supported any longer? And if so, what is an alternative way of adding a menu item to menus in the Editor toolbar?

Hi Rxanadu, you need to import UnityEditor example:

using UnityEngine;
using UnityEditor;
using System.IO;

//Generate Folders in our project	

namespace Assets.Editor.Menu
{
    public class FolderSetup
    {
        //Add menu item
        [MenuItem("Project Tools/FolderSetup")]
        //Init
        private static void Init()
        {
            GenerateFolders();
        }

        //Generate folder and names
        private static void GenerateFolders()
        {
            var projectPath = Application.dataPath + "/"; //Store project Path

            //Create folders
            Directory.CreateDirectory(projectPath + "Audio");
            Directory.CreateDirectory(projectPath + "Fonts");
            Directory.CreateDirectory(projectPath + "Materials");
            Directory.CreateDirectory(projectPath + "Meshes");
            Directory.CreateDirectory(projectPath + "Prefabs");
            Directory.CreateDirectory(projectPath + "Resources");
            Directory.CreateDirectory(projectPath + "Scenes");
            Directory.CreateDirectory(projectPath + "Scripts");
            Directory.CreateDirectory(projectPath + "Textures");

            AssetDatabase.Refresh(); //Refresh Project folder in editor
        }
}
}

I can’t test it right now, but that the way i was doing menuitem!

It works! I take it the Init() function is needed for this to work (i.e. for GenerateFolders() to be called at all). Is there an alternate way in doing this? I’m new to C#, so I’m guessing Init() functions similarly to main() in Java. Am I correct in saying this?
