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() {}Practice Menu Command Simulation
Simulate menu path: execute Debug.Log("Menu calisti: " + menuYolu);.
Starter code
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";
// menuYolu ile konsola mesaj yazdir
}
}Sample 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);
}
}Expected output
Menu calisti: Araclar/Temizle
