// Return false if no transform is selected.
return Selection.activeTransform != null;
}
This simple validator just checks whether you have a game object selected in the editor; if
not, then
MenuItem1
is disabled.
This new validation function is evaluated by the editor whenever it displays the menu
item of the same name. By setting the
bool
flag at the end of the
MenuItem
attribute, it
tells the editor that this function provides the validation logic for a
MenuItem
attribute of
the same name. Then, the editor will enable or disable that
MenuItem
attribute based on
the return of the validator function.
Adding shortcut keys to a MenuItem attribute
If you add
%
and a letter to the end of your
MenuItem
attribute, Unity will also enable a
shortcut key for that letter.
So,
%g
would enable a shortcut of
Ctrl
+
G
on Windows and
cmd
+
G
on a Mac.
For example, add a new function to our
MyMenu
script as follows:
[MenuItem ("MenuName/MenuItem2 %g")]
static void EnableMyOtherAwesomeFeature()
{
Debug.Log ("Find my key and win the prize - g");
}
This will show us an additional option with the shortcut defined, as you can see here:
