I love this addition. It truly gives more control and freedom. Thank you! |

Ok I didn't know I needed this but I need this good job and thanks! |

I'm debating the property name. Maybe we should start naming properties in more readable format instead of keeping it consistent with existing properties? It's fine for short names but the more complex property names feel kind of unreadable. In this case for example |

How about |

This property toggles automatic vehicle engine state behavior (
trueby default).By default game turns on the engine automatically on driver enter and turns off the engine on driver exit for aircraft. This property allows us to disable this behavior and allow full control of vehicle engine state by using setVehicleEngineState.
In addition to disabling automatic engine state behavior I modified aircraft logic to allow rotors to spin without driver (if engine is on) and to prevent spinning if engine is off with driver inside. Existing hook is used to add additional changes to rotors state.
So this way the driver can leave helicopter with engine running. And it's possible to fly away instantly because rotors will keep spinning all the time while the engine is on.
At this moment we can achieve this kind of behavior using setVehicleRotorState and setVehicleRotorSpeed. This property works differently because it makes it based on the vehicle engine state instead of rotor state (which should be easier to use and more common).
Note
The game will not spin up rotors to maximum speed instantly if unoccupied helicopter with running engine just streamed in (like player teleporting to a location with helicopter that has engine on and no driver). It can be mitigated using setVehicleRotorSpeed if necessary although not really needed in most use cases.
Warning
To avoid possible engine state desynchronization between server and client it's recommended to use it on server side only with appropriate minclientversion (like some other existing world properties).
