MenuItem

Learn to add a menu entry with MenuItem.

Adding to the Top Menu with the MenuItem Attribute

To add custom tools or functions to Unity's top menu bar, the [MenuItem("Menu/Path")] attribute is used. This attribute is placed above a static method and invokes it when clicked.

[MenuItem("Tools/Clear Enemies")]
static void ClearEnemies()
{
    Debug.Log("Enemies cleared");
}

Defining Keyboard Shortcuts

Keyboard shortcuts can be configured by appending special modifier symbols to the MenuItem path. For example, % represents Ctrl/Cmd, # represents Shift, and & represents Alt. This accelerates recurring actions with a single keystroke combination.

// %g -> represents Ctrl+G or Cmd+G shortcut
[MenuItem("Tools/Quick Create %g")]
static void QuickCreate() {}

Exercise Menu Command Simulation

Simulate menu path: execute Debug.Log("Menu calisti: " + menuYolu);.

Show example solution

using System;

public static class Debug
{
    public static void Log(object message) => Console.WriteLine(message);
}

public class Program
{
    public static void Main()
    {
        string menuYolu = "Araclar/Temizle";
        Debug.Log("Menu calisti: " + menuYolu);
    }
}
