# This is our main module. Think of it as the brain of our tunnel.
# It connects the gameplay events (player entering) to the audio changes.

# We define our devices here. These are the "actors" in our scene graph.
# We need a way to detect players, a way to play music, and a way to filter it.
# Note: In a real setup, you'd link these via the editor, but here we define
# the structure. For this tutorial, we assume you've placed:
# 1. A Music Player (linked to a Filter)
# 2. A Trigger Volume
# 3. The Filter device itself

# This function runs when a player enters the trigger.
# It's like the "On Player Enter" event in the device menu, but we control the knob.
On_Player_Enter := func(Player : Player) : void =>
{
    # Find the Patchwork Filter device in the world.
    # In a real island, you'd have a reference to this device placed in the editor.
    # For this example, let's assume we have a global reference called 'MyFilter'.
    
    # We want to set the Cutoff frequency low.
    # Low-Pass means we cut highs. A low cutoff (e.g., 500 Hz) makes it very muffled.
    # A high cutoff (e.g., 20,000 Hz) lets everything through.
    
    MyFilter.Set_Cutoff(500.0)
    
    # Optional: Add a little drama by changing the filter type if you want
    # MyFilter.Set_Filter_Type(Low_Pass)
