Does altering station_roll have an affect?

[Flying_Circus]

If so, what numbers should I give it, to make it have a visible effect?

[JensAyton]

It is loaded, iff the station has “station” among its roles. The default value is 0.4.

Herm, so does "station" predefine any other behaviour, Ahruman?

[JensAyton]

The only other case I can find is that in order for something to be considered a StationEntity – i.e., a ship which can be docked with – it must have "station" or "carrier" among its roles, or have a <key>isCarrier</key><true/> in its definition.

Do you need a dockable/station-like thing that doesn’t have a "station" role? For what purpose?

[JensAyton]

On closer inspection, it looks like ''station_roll'' also requires <key>rotating</key><true/> to have an effect (or a role of "rotating-station", but that’s deprecated).

Thanks for clarifying that. I have a large carrier that rolls as it flies. I suppose that makes it a flying space station. It is already defined as a carrier - and it wil roll, when asked to - but when asked to roll at a specific speed, this is ignored.

I am assuming they both inhertit from the same basic class, but that the ability to define station roll-speed is hard wired into the station?

I should just try it and see (or, indeed, look at the source code, to see if I can work out what will happen). I just had visions of creating a ship that could only ever fly along facing the planet, or something :-/.

Internally, any dockable ship is a station. As far as I can see, a constant rolling effect can be applied with the “rotating” key and modified with the “ station_roll” key if the thing has a “station” role. This is an effect of stuff that happens in various bits of StationEntity and Universe, though, so it’s quite possible I’m missing something.
