# 1. Define our Device
# This is the "Actor" sitting in your level.
# Think of it like a Button Device, but smarter.
ChaosButtonDevice = device:
    # 2. Variables (The Loot Pool)
    # These are the items that can spawn.
    # We define them as a list (array) of weapon IDs.
    WeaponPool := ["ItemID_CombatAssaultRifle", "ItemID_CombatShotgun", "ItemID_CombatSMG"]
    
    # 3. The Widget Reference
    # We need a place to store the widget so we can interact with it later.
    # In Verse, we often use a "Handle" to keep track of spawned objects.
    ChaosMenuHandle: handle<widget> = uninitialized
    
    # 4. The Main Logic Function
    # This runs when the device is initialized (spawns into the world)
    OnBegin<override>()<suspends>: void =
        # --- PHASE 1: SPAWN THE UI ---
        
        # First, we need to actually create the widget.
        # We assume you have a widget blueprint named "ChaosMenu" in your Content Browser.
        # If you haven't made one, create a Widget Blueprint -> Modal Dialogue Variant.
        MenuWidget := CreateWidget<ChaosMenu>()
        
        # --- PHASE 2: MAKE IT INTERACTIVE ---
        
        # This is the CRITICAL STEP.
        # We add the widget to the player's UI slot.
        # The argument `player_ui_slot{InputMode := ui_input_mode.All}` 
        # is the "pen" we talked about earlier. It allows clicking.
        # Without this, the button is just a picture.
        ChaosMenuHandle := AddWidget(MenuWidget, player_ui_slot{InputMode := ui_input_mode.All})
        
        # --- PHASE 3: BIND THE EVENT ---
        
        # Now we find the Button inside our widget and wire it up.
        # We assume your widget has a Button named "ChaosButton".
        # If your button is named differently, change "ChaosButton" below.
        Button := ChaosMenuHandle.GetWidgetByName<Button>("ChaosButton")
        
        # Here we bind the event.
        # When the button is clicked, run the function "OnChaosButtonClicked".
        Button.ClickedEvent.Bind(OnChaosButtonClicked)

    # 5. The Reaction Function
    # This is what happens when the player actually clicks the button.
    OnChaosButtonClicked: () -> void =
        # Pick a random weapon from our pool
        RandomIndex := RandomInt(0, 3) # 0 to 2
        SelectedWeapon := WeaponPool[RandomIndex]
        
        # Give the player that weapon
        # We use the current player's context to grant the item
        # Note: In a real device, you'd need to get the player reference.
        # For this simple example, we'll just print to debug to prove it works.
        Print("Chaos Button Pressed! Spawning: ", SelectedWeapon)
        
        # If you want to actually spawn it, you'd use:
        # GrantItem(SelectedWeapon)
