Just trying to find out how to attach a trailer to a ground vehicle AI
simobject. When looking at the baggage tugs with trailers attached around the
default gates it’s apparently possible. ASO_Tug01\sim.cfg shows the following
promising entry: [WagonLink] backLinkLength = 0 ; meters, positive length of
the link between wagons at the back of the vehicle backLinkStartPosition =
-1.353 ; meters, signed position along the “forward” axis of the start of the
back link I couldn’t however find any more information in how to set this up
for custom made simobjects. Is there any information about this available
somewhere or can someone give another hint where to look for it? Thanks!

Ok, I did some further reading on this topic and have found out now there’s a
nice documentation on this in the SDK (I could have sworn it wasn’t there when
I opened this topic but maybe I was just blind ;)).
https://docs.flightsimulator.com/html/index.htm#t=Content_Configuration%2FSimObjects%2FGround_Vehicles%2FBaggageCart_Definition.htm
Problem however is that this doesn’t describe how custom “trains” of tugs and
dollys are brought into action WITHOUT setting up a new living world cfg. As I
understand it living world cfg’s impose global changes in the respective hard-
coded region (Region K, A, X… and so on…). As I understand it the current
approach is as follows: Services.SPB calling the BaggageLoader.SPB:
BaggageLoader
Shared\Asobo_BaggageLoader\BaggageLoader
BaggageLoader
1.000
0.950
2.000
45.000
-140.000
BaggageLoader.SPB calling AIType=BaggageCart (among others) from the
RegionContainerType:
BaggageLoader
true
true
BaggageLoader
true
GroundVehicle_Pilot
BaggageCart
true
true
BaggageCart
-9.000,0.000,5.000,0.000
0.000,0.000,315.000
true
GroundVehicle_Pilot
With the RegionContainerType for BaggageCart defined in Asobo_LWcfg.SPB :
ASO_Tug01_White
1
ASO_Tug02_White
1
ASO_Baggage_Cart01
6
ASO_Baggage_Cart02
6
(Just find it a bit weird that the “VehicleFollower”<>“” described in
https://docs.flightsimulator.com/html/index.htm#t=Content_Configuration%2FEnvironment%2FLiving_World%2FAirport_Services%2FService_And_IdleWorker_Script_Definitions.htm
isn’t used anywhere) Is this really how things are set up and is there no
straight way in setting up vehicles with trailers attached without doing
global living world region changes?
