Traffic Light Controller V0.1

Automatically turns traffic lights green for emergency vehicles when sirens are activated. Drive any emergency vehicle with sirens on and traffic lights will change to green as you approach.

Features:
Automatic green lights when driving emergency vehicles with sirens on, holds the light green for you until you pass
Smart detection thanks to CJunction::GetJunctionAtPositionForTrafficLight
Other directions stay red until you pass through
Works with all emergency vehicles (police, fire, ambulance, etc.)
Debug mode for troubleshooting (type tlcdebug in cheat console)

How it works:
The plugin uses pattern scanning to hook into the game’s junction system (CJunctions). When sirens are active, it:

Finds nearby junctions using GetJunctionAtPositionForTrafficLight
Detects which entrance you’re approaching based on position + velocity
Sets CJunction::m_iLightPhase to your entrance’s phase
Holds m_fLightTimeRemaining at 10s until you pass

Requirements:
GTA V (Single-player Legacy only)
ScriptHookV by Alexander Blade

Installation:
Install ScriptHookV if you haven’t already
Copy TrafficLightController.asi to your GTA V root folder

Known Limitations:
Single-player only
Beta release – may have occasional detection issues at complex junctions
AI driving emergency vehicles does not affect traffic lights (yet)
