Worked on the Synesthesias/PLATEAU-SDK-Toolkits-for-Unity repository to deliver a targeted API enhancement for Unity-based simulations. Focused on SDK development using C#, the work involved exposing public getters for trafficLightGroups and lightingSequences within the TrafficIntersection class. This minimal, non-breaking change made existing data structures accessible to external tools, streamlining integration with downstream exporters and reducing the need for manual data access. By enabling external access to key traffic intersection data, the update improved the efficiency of road network exports and supported more robust workflows for Unity SDK users, while maintaining the stability and integrity of the existing codebase.
