What problem does it solve? Manually scripting CARLA's LightManager to control street lamps, building lights, and vehicle lights requires knowing the API, light groups, and common failure modes like synchronous-mode snapshot issues. This Skill encodes the vetted procedure so an agent can switch, colour, and dim the world's light sources without improvising. ## Core Features & Use Cases - Group-based light control: Turn street, building, vehicle, other, or all light groups on/off, and set colour (RGB) and intensity per group. - Day-night cycle toggle: Enable or disable automatic lights-at-night switching tied to the sun position. - Prerequisite checking: A check_env.sh script verifies the carla Python module is importable and the server is reachable before any command runs. - Use Case: To create a lit-up night city scene, set the sun below the horizon with set-weather, then run lights.py on --group street --color 255,220,150 --intensity 2000 and on --group building. ## Quick Start Ask the agent to turn on the street lights with a warm colour and high intensity so the city is lit up at night.
