Use Subscribe Wrapper for more than 1 variable

[Rastarocket1]

Hi, so I found this wrapper snippet and was wondering if I can use it for 2 or more variables and if so, how. Thanks in advance

You can just make the function take a tuple() as a param and pass extra data this way

event_wrapper(t:type, t2:type) := class:
    ExtraData : t2
    InFunction : type{func(:t, :t2):void}
    ProxyFunction(T:t):void=
        InFunction(T, ExtraData)

(S:subscribable(t)).SubscribeExtraData(InFunction:type{func(:t, :t2):void}, ExtraData:t2 where t:type, t2:type)<transacts>:cancelable=
    Wrapper := event_wrapper(t, t2):
        ExtraData := ExtraData
        InFunction := InFunction
    S.Subscribe(Wrapper.ProxyFunction)

test_device := class(creative_device): 
    
    @editable Button : button_device = button_device{}
    
    OnBegin<override>()<suspends>:void=
        Button.InteractedWithEvent.SubscribeExtraData(OnButtonClicked, (0, "String"))

    OnButtonClicked(Agent:agent, ExtraParams:tuple(int, string)):void=
        I := ExtraParams(0)
        S := ExtraParams(1)
        Print("Button Clicked {I} {S}")
