Internals

Light Objects Found by Name

Stage Lights:

• Prestagelight_l, Prestagelight_r
• Stagelight_l, Stagelight_r

Countdown Lights:

• Amberlight1_R/L, Amberlight2_R/L, Amberlight3_R/L
• Greenlight_R/L
• Redlight_R/L

Digit Displays:

• display_time_1-5_l/r
• display_speed_1-5_l/r

How It Works

1. initLights() finds all light scene objects by name and hides every one of them (stage lights + countdown lights).
2. clearDigits() finds all 20 digit display objects and hides them.
3. Both operations run every frame when flow is active (designed to be triggered once on mission cleanup).

Lua Example

-- Typical flowgraph connection:
-- Mission "abandoned" or "completed" flow → this node's flow in
-- Ensures the drag strip is visually reset for the next race

Key Dependencies

• scenetree.findObject() - locates light and display objects by name
• _flowgraph_createNode() - standard flowgraph node registration

Additional Methods

C:_executionStarted()

Called when graph execution starts. Used for initialization/reset.

C:work()

Main work function called each frame/tick when the node is active.
