How It Works

Pro Tree Mode

1. At 2.0s: All 3 amber lights on both sides illuminate simultaneously.
2. At 2.4s: Ambers turn off, green lights turn on → race started.
3. Total countdown: ~2.4 seconds.

Sportsman Tree Mode

1. At 1.0s: First amber lights on.
2. At 1.5s: Second amber lights on (first off).
3. At 2.0s: Third amber lights on (second off).
4. At 2.5s: Green lights on → race started.
5. Total countdown: ~2.5 seconds.

Jump Start Detection

• If distance > 0.2 before the green light, the player is disqualified.
• Red lights illuminate on both sides, ambers and greens are hidden.
• The disqualified output fires.

Key Dependencies

• scenetree.findObject() - locates Amberlight, Greenlight, Redlight scene objects
• _flowgraph_createNode() - standard flowgraph node registration
