# This is the main structure for our island logic.
# Think of this as the "Brain" of our platform system.
platform_vanisher := class(creative_device):

    # 1. DEFINE THE VARIABLES
    # We need to tell Verse which devices we are controlling.
    # @editable means we can drag-and-drop devices from the editor into these slots.
    # This is safer than hard-coding names, and it's how Verse actually resolves
    # device references at edit time.

    # Here, we define the trigger zone.
    # trigger_device is the real Verse type for the Trigger Device in UEFN.
    @editable
    PlatformTrigger : trigger_device = trigger_device{}

    # Here, we define the platform itself.
    # creative_prop is the real Verse type for a placeable Static Prop in UEFN.
    @editable
    MyFloatingPlatform : creative_prop = creative_prop{}

    # 2. DEFINE THE ENTRY POINT
    # OnBegin runs automatically when the game session starts.
    # This is where we wire up our event listener so it is ready before
    # any player can step on the platform.
    OnBegin<override>()<suspends> : void =
        # Subscribe to the TriggeredEvent on the trigger device.
        # AgentTriggeredEvent fires whenever any agent (player) enters the zone.
        # Await blocks here until the event fires, then calls our handler.
        loop:
            MaybeAgent := PlatformTrigger.TriggeredEvent.Await()
            if (Agent := MaybeAgent?):
                OnPlayerEnteringZone(Agent)

    # 3. DEFINE THE EVENT HANDLER (The "Wake Up" Call)
    # This function runs each time a player enters the trigger zone.
    OnPlayerEnteringZone(Agent : agent) : void =
        # 4. TAKE ACTION
        # When this event fires, we disable the platform we stored above.
        # Hide() hides the prop and removes its collision,
        # so the player falls straight through.
        MyFloatingPlatform.Hide()

        # Print a message to the debug console to prove it worked.
        Print("Platform vanished! Goodbye, player.")
