(Solved) UI | OnClick cannot be subscribed to a Player?

Development Programming & Scripting

When setting up custom UI elements, I cannot figure out if/how the OnClick subscribable function can be subscribed to a player. If not, this greatly limits the amount of devices custom UI can interact with.

Hi Axel,
I haven’t played around with it on my side yet, but looking at the UI API, inside Fortnite.digest.verse and EpicGames.digest.verse:

  • text_button_base.OnClick can Subscribe a function that receives a widget_message.
  • widget_message is defined as
widget_message<native><public> := struct:
            Player<native><public>:player
            Source<native><public>:widget

This means you should be able to use the Player reference to the player that clicked the button for further processing.

ButtonTest:button_regular = button_regular{DefaultText:="ClickMe"}

OnButtonClicked(Message:widget_message):void=
        # Operate on Message.Player

OnBegin<override>()<suspends>:void=
        ButtonTest.OnClick.Subscribe(OnButtonClicked)

Hi @DiG3, thanks for the response!

Following the above causes an Unkown identifier 'Player' error!

The code:

Home:button_quiet=button_quiet{ DefaultText := "Home" }

OnBegin<override>()<suspends>:void=
Home.OnClick.Subscribe(HomeSelected)

HomeSelected(Message:widget_message):void = {
        GoToHome(Player) #This is a Player Function
        Print("Home Selected")
        if (Button := text_button_base[Message.Source]) {
            Button.SetText("Home")
        }

Player is a field/member of widget_message, so accessing it this way should work: GoToHome(Message.Player).
