Question

I’m making a top down deck builder RPG and I want to make it so that when a card is clicked on it will emit a signal. I know how to create signals and emit them, but I’ve had trouble connecting them. because I want the cards to be in their own scene and added with add_child() I can’t connect the signal through the node tab in the inspector. I’ve tried looking at tutorials on signals but none of the tutorials worked. can somebody please show me how to connect the signals? I’m using a button that I want to emit a clicked signal so that way it can be picked up by what will be the scenes root. I’m happy to give more context if needed!

You can connect to dynamically created nodes using the connect function on your desired signal

func _ready() -> void:
    var new_button: Button = Button.new()
    new_button.text = "A button"
    add_child(new_button)

    # connecting to the `pressed` event
    new_button.pressed.connect(handle_button_press)

func handle_button_press() -> void:
    print("A button was pressed!")
