# --- THE TURRET LOGIC ---

# This function checks the turret's health.
# Effect: reads
# Why? Because we are just looking at the health number.
# We aren't changing it. It's like checking your shield bar.
Get_Turret_Health := function(turret: CreativeDevice): int =>
    # GetHealth is a standard device function.
    # It returns an integer (whole number).
    turret.GetHealth()

# This function makes the turret fire.
# Effect: writes
# Why? Because it changes the state of the game (spawns a projectile).
# It might also reduce ammo, which is a write operation.
Fire_Turret := function(turret: CreativeDevice): void =>
    # This is a placeholder for the actual firing logic.
    # In real Verse, you'd call something like:
    # turret.Fire() or spawn_projectile(...)
    # Since this changes the world, it has the 'writes' effect.
    print("Turret fires at intruder!")

# This is our main event handler.
# It runs when a player enters the trigger zone.
# Effect: reads (initially checks state), writes (triggers action)
On_Player_Enter := function(player: Player, trigger: TriggerDevice): void =>
    # Step 1: READ the turret's health.
    # We are observing, not changing.
    current_health := Get_Turret_Health(trigger.GetAssociatedCreativeDevice())
    
    # Step 2: DECIDE based on that read.
    if current_health > 0:
        # Step 3: WRITE to the world.
        # The turret fires! This changes the game state.
        Fire_Turret(trigger.GetAssociatedCreativeDevice())
    else:
        print("Turret is destroyed. No revenge today.")

# --- THE SETUP ---

# To make this work, you need to set up your island:
# 1. Place a Trigger Device.
# 2. Place a Creative Device (like a Turret or Spawner) and link it to the Trigger.
# 3. Attach a Script Device with this Verse code.
# 4. Link the Script to the Trigger's "On Actor Enter" event.
