Articulated vehicles

[sky81]

I'm trying to figure out how to add an articulated vehicle but with no success. As starting point I've try to understand eGRVTS2
So I've deleted the last part, and remain to nfo code until "1 Horse Small Passenger Carriage". This vehicle contain the horse and the carriage. But there are several carriages with ids from FF 00 to FF 0B (starting from no2170 from nfo)
I saw that "1 Horse Small Passenger Carriage" is articulated with carriage with id FF 00 (because the actual passenger capacity is 4(from horse - no10795 in nfo) + 16 from carriage ID FF 00 (no2180 in nfo).
Can you tell me how to articulate the vehicle to another carriage? (example to carriage FF 02)?
I cannot figure out how to change the carriage
Thanks

Hi, I suggest you leave NFO aside and use NML, it will be much easier to understand and much faster.

First you can understand how to make a simple vehicle, and then you can try the articulated one. It's not much different. The easiest way to do it is to create two vehicles and assign the second one as an articulated part of the first.

Here's an NML tutorial for a vehicle; it's several pages long:

Yes. I saw that nml is much easier. Still, I'm curios on the attached nfo how is the vehicle attached to the carriage. I spend a lot of time and could not figure out.
Thanks

Decompiling nfo is not a great way to understand newgrf coding, as you lose any formatting and comments.

In any case, articulated vehicles in nfo are constructed using callback 16.
