**1. Trigger Area**

Each track has its own TriggerArea, which has a BoxCollider that will only accept touch input if you hit inside the collider.

**2. Note Area**

The NoteArea is used to detect whether a note is in range for the trigger, and it handles most of the note trigger logic.

**3. Line Area**

This marked the position for the note to hit at the corresponding time and also used to calculate how precise a note is being triggered.

**4. Mask**

This is a simple sprite mask, important for hiding the long note part

### Bonus

Each track is a self-contained prefab, and in runtime, the notes will be parented under each individual track, so it's also possible to move each track during runtime, or position differently.
