Vehicle Spawner — spawn a drivable vehicle a player can hop into and drive

The race starts — a bike roars onto the track and the player jumps in.

race_manager := class(creative_device):
    @editable
    Bike : vehicle_spawner_sportbike_device = vehicle_spawner_sportbike_device{}
    OnDriverEnters(Agent : agent) : void =
        Bike.AssignDriver(Agent)
    OnDriverExits(Agent : agent) : void =
        Bike.RespawnVehicle()
    OnBegin<override>()<suspends>:void =
        Bike.RespawnVehicle()
        Bike.AgentEntersVehicleEvent.Subscribe(OnDriverEnters)
        Bike.AgentExitsVehicleEvent.Subscribe(OnDriverExits)

Takeaway — Reach for vehicle_spawner when you need drivable vehicles your code controls.
