# This is a Verse script that listens for a button press
# and triggers a prop-mover to launch a player.

# 1. IMPORTS
# We need to import the 'Devices' library to access Button,
# Prop-Mover, and their built-in events.
using { /Fortnite.com/Devices }
using { /Verse.org/Simulation }

# 2. THE SCRIPT STRUCTURE
# This is the container for our logic.
# Think of it as the "Island" itself, but for this specific mechanic.
# In UEFN, you attach this creative_device to your Button device
# in the level, and wire the PropMover reference in the editor.
LaunchPadScript := class(creative_device):

    # 3. DECLARING OUR DEVICES
    # We need references to the actual devices in our level.
    # In the UEFN editor, drag your Prop-Mover device into the
    # 'PropMover' field that appears on this script component.
    @editable
    PropMover : prop_mover_device = prop_mover_device{}

    @editable
    RevengeButton : button_device = button_device{}

    # 4. OnBegin — the entry point
    # OnBegin runs automatically when the game session starts.
    # This is where we subscribe to events so our code starts listening.
    OnBegin<override>()<suspends> : void =
        # 5. SUBSCRIBING TO THE EVENT
        # 'InteractedWithEvent' fires whenever a player presses
        # this button. We pass our handler function to Subscribe
        # so Verse knows what code to run when it fires.
        # This is the code equivalent of drawing a wire in the editor.
        RevengeButton.InteractedWithEvent.Subscribe(HandleButtonPress)

    # 6. THE FUNCTION
    # This function runs ONLY when the event above fires.
    # It takes a 'player' as input (the person who pressed the button).
    HandleButtonPress(Agent : agent) : void =
        # 7. TRIGGERING THE DEVICE
        # We call Begin() on our Prop-Mover.
        # This is the function that does the work — springing the trap!
        PropMover.Begin()
