Unity Editor Extensions –menu Items

Reference: Https://unity3d.com/cn/learn/tutorials/topics/interface-essentials/unity-editor-extensions-menu-items

　　

The Unity MenuItem property class allows you to extend the main menu, the property Bar content menu, the hierarchy Bar menu, and the Resource bar menu.

MenuItem can convert any static function to a menu command, only the static function can use the MenuItem property.

Add menu Options

Add a Simple Main menu button

using Unityeditor; using Unityengine;

public class MenuItems{    [MenuItem("Tools/Clear PlayerPrefs")]    private static void NewMenuOption() { PlayerPrefs.DeleteAll(); }}

shortcut Keys

The following modifier keys and special keys (which can be used in conjunction) are supported:

• %–ctrl on Windows/cmd on OSX
• #–shift
• &–alt
• Left/right/up/down–arrow keys
• F1 ... f2–f keys
• HOME, END, PgUp, PGDN

If you do not use a modifier key, you need to add an underscore before the shortcut key, such as: _g for shortcut G, shortcut text must be preceded by a space, otherwise the shortcut key does not work.

//Add a new menu item with hotkey ctrl-shift-a[MenuItem ("tools/new Option% #a")]Private Static voidnewmenuoption () {}//Add a new menu item with hotkey Ctrl-g[MenuItem ("Tools/item%g")]Private Static voidnewnestedoption () {}//Add a new menu item with hotkey G[MenuItem ("tools/item2 _g")]Private Static voidNewoptionwithhotkey () {}
