Update Display Drag Race (Flowgraph Node)

Overview

• Node Name: Update Display Drag Race
• Category: repeat_instant
• File: extensions/flowgraph/nodes/mission/UpdateDisplayDragRace.lua

Updates the physical digit displays (time and speed) for drag race missions. Swaps 3D display models to show numeric digits.

How It Works

1. Reset: Finds scene objects named display_time_N_l/r and display_speed_N_l/r (N = 1–5) and stores references.
2. Display Update: Formats time to 3 decimal places and speed to 2 decimal places.
3. Each digit is mapped to a 3D model: art/shapes/quarter_mile_display/display_N.dae where N is the digit (or empty for leading zeros).
4. Speed is converted from m/s to mph by multiplying by 2.237.
5. The side pin selects which set of displays to update (left or right lane).

Lua Example

-- Scene objects must exist in the level:
-- display_time_1_l through display_time_5_l (left lane time)
-- display_speed_1_l through display_speed_5_l (left lane speed)
-- Same pattern with _r suffix for right lane

-- Time "9.123" → digits: "empty", "9", "1", "2", "3"
-- Speed "123.45" → digits: "1", "2", "3", "4", "5"

Key Dependencies

• scenetree.findObject() - locates display digit scene objects by name
• 3D models at art/shapes/quarter_mile_display/display_*.dae
• _flowgraph_createNode() - standard flowgraph node registration

Additional Methods
