MenuItem

説明

MenuItem 属性によりメインメニューとインスペクターのコンテキストメニューにメニューアイテムを追加できます。

MenuItem 属性を使うと、どんな静的関数でもメニューコマンドにできます。静的関数のみ MenuItem 属性を使用できます。

To create a hotkey you can use the following special characters: % (ctrl on Windows and Linux, cmd on macOS), ^ (ctrl on Windows, Linux, and macOS), # (shift), & (alt). If no special modifier key combinations are required the key can be given after an underscore. For example to create a menu with hotkey shift-alt-g use "MyMenu/Do Something #&g". To create a menu with hotkey g and no key modifiers pressed use "MyMenu/Do Something _g".

Some special keyboard keys are supported as hotkeys, for example "#LEFT" would map to shift-left. The keys supported like this are: LEFT, RIGHT, UP, DOWN, F1 .. F12, HOME, END, PGUP, PGDN, INS, DEL, TAB, SPACE.

ホットキーの文字列の前にスペース文字を含める必要があります( "MyMenu/Do _g" はホットキーとして認識されず、一方で "MyMenu/Do _g" は認識されます)

When adding menu items to the "GameObject/" menu for creating custom game objects be sure to call GameObjectUtility.SetParentAndAlign to ensure that the new GameObject is reparented correctly in the case of a context click (see example below). Your function should also call Undo.RegisterCreatedObjectUndo to make the creation undoable and set Selection.activeObject to the newly created object. Also note that in order for a menu item in "GameObject/" to be propagated to the hierarchy Create dropdown and hierarchy context menu, it must be grouped with the other GameObject creation menu items. This can be achieved by setting its priority to 10 (see example below). Note that for legacy purposes MenuItems in "GameObject/Create Other" with no explicit priority set will receive a priority of 10 instead of the default 1000 - we encourage using a more descriptive category name than "Create Other" and explicitly setting the priority to 10.

    }

    // and propagated to the hierarchy dropdown and hierarchy context menus.

        Undo.RegisterCreatedObjectUndo(go, "Create " + go.name);
