Set Stage Lights (Flowgraph Node)

Overview

• Node Name: Set Stage Lights
• Category: repeat_instant
• File: extensions/flowgraph/nodes/mission/stageLightsDragRace.lua
• Icon: AI icon
• Color: AI color

Activates or deactivates the Pre-Stage and Stage lights on the drag-race Christmas tree. Controls individual lane sides (left/right) independently. Used alongside lightsController for the full countdown sequence.

Pin Schema

Input Pins

Output Pins

Internals

• self.lights.stageLights - table of four scene objects: prestageLightL, prestageLightR, stageLightL, stageLightR.
• postInit() sets up hard templates for the side and light pins (dropdown values in the editor).
• initLights() resolves scene-tree objects by name.

How It Works

1. Reset - When reset fires, calls initLights() to resolve scene objects, then hides all four stage lights.
2. Normal operation - Based on the side and light input values, unhides the corresponding light object:
   • side="l" + light="preStage" → show prestageLightL
   • side="l" + light="stage" → show stageLightL
   • side="r" + light="preStage" → show prestageLightR
   • side="r" + light="stage" → show stageLightR

Lua Code Example

-- In a drag race flowgraph:
-- vehicle enters pre-stage zone → stageLightsDragRace (side="l", light="preStage")
-- vehicle enters stage zone → stageLightsDragRace (side="l", light="stage")
-- Both lanes staged → lightsController begins countdown

Key Dependencies

• scenetree.findObject(name) - requires named light objects: "Prestagelight_l", "Prestagelight_r", "Stagelight_l", "Stagelight_r"

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.
