# This is our "Loot Goblin" component.
# It attaches to a Button device and waits to spawn a crate.
#
# HOW TO SET UP IN UEFN:
#   1. Place a button_device in your level.
#   2. Place a prop_mover_device in your level; set its
#      initial state so the crate is hidden off to the side.
#   3. Select the button_device, click Add -> New Verse Component,
#      and choose this file.
#   4. In the component's Details panel, drag your prop_mover_device
#      into the TargetProp slot.

    # respond whenever any player presses it.

    # When the button is pressed, this function fires.
    # Think of this as the "Trigger" on a trap.
    # <suspends> lets us call Sleep without freezing the game.
    OnButtonPressed(Agent : agent) : void =
        spawn:
            WaitThenSpawnLoot()

    WaitThenSpawnLoot()<suspends> : void =
        # 1. Tell the player something is happening.
        # Print acts like a chat message or system notification.
        Print("Loot is coming... get ready!")

        # 2. The Magic Pause.
        # We tell the simulation to wait 5.0 seconds.
        # The game does NOT freeze. Other players can still move.
        Sleep(5.0)

        # 3. After the 5 seconds are up, activate the PropMover.
        # The PropMover should be configured in UEFN to move
        # the crate into its visible, final position when activated.
        TargetProp.Activate()

        # 4. Let the player know the loot is here.
