VScript API
IMPORTANT
VScript is currently discontinued and all progress on it has been halted. This documentation is provided as-is and may not be accurate.

⚠️ The current state of VScript ⚠️
As of the mirage update, VScript is intentionally disabled by Valve. This means that the lua runtime is no longer available in the base game. While there are patches that re-enable VScript, we do not recommend using them as they might stop working at any point in time. Valve has been working on a new scripting system (Pulse) for a while now, but it is not yet1 available to the public.
