[Lua] Automatic extend/retract Landing Gear

[_MOHAPX_]

You need telemeter.

--add item telemeter to bottom ship
--connect telemeter to seat
--rename slot in control unit editor to "telemeter"

--add to system.update()

--Auto extend/retract gear
local speed = math.floor(vec3(core.getWorldVelocity()):len() * 3.6)
if telemeter.getDistance() < 5 and speed < 10 then
    if Nav.control.isAnyLandingGearExtended() == 0 then Nav.control.extendLandingGears() end
else
    if Nav.control.isAnyLandingGearExtended() == 1 then Nav.control.retractLandingGears() end
end

If you’re not worried about underwater landing gear, you don’t even need a telemeter.  This can be accomplished just by linking a hover engine to the core and using (iirc) the distance() method.

Example pls. Will the distance be calculated to the object below or to the sea level?

When I follow these instructions, I get an error saying null value for Telemeter. I renamed the element. I am sure it has something to do with this but can't figure it out.

Yeah, a similar script works on another ship of mine - but on the new ship I am building I cannot even link the telemeter to the command seat ("no compatible link type ...").
So, I do not then see the telemeter "slot" - thus I cannot rename it.
Was there any change I am not aware of?
How am I supposed to link the telemeter now?
