Description

In longer trains, the requested behavior is to have ABBA (with the last 2 being reversed) instead of ABAB (not being reversed).

What is required:
List of vehicles affected, and added sprites for the reversed part (additional rows in which the sprites are in a different order?)

What if there is an odd number of vehicles after each other? Can it then always be a forward facing A unit, or should that depend on the part in front of it?

Feature #7922: B-unit behavior changed to also have back A and B units

History

#1 Updated by Transportman over 2 years ago

Affected vehicles: GNR EMD F3, UP EMD E8, PRR RF-16, VIA Rail FP9, Pacific National XR

#2 Updated by EmperorJake over 2 years ago

Can we scratch the SDP40f off the list, it doesn't have a true b-unit so the current behaviour is fine. Also can we add the Pacific National XR.
I'll post the fixed sprites in a couple days when I get home.

Also, would it be possible to put a random switch on the last unit so it's possible to get both A-B-B and A-B-A consists?

#3 Updated by EmperorJake over 2 years ago

New spritesheets for all affected vehicles, hopefully the alignments are all correct.

#4 Updated by Transportman over 2 years ago

Alignments look good to me.

Order for new vehicles
A forward
B forward
B reverse
B forward
B reverse
A reverse (last unit)

#5 Updated by EmperorJake over 2 years ago

The order looks good. The last vehicle should be somehow selectable (either via a refit or a random switch) no matter how many vehicles are in the consist, that way if you have only 2 units you can get either A-A back to back or an A-B set like the current behaviour. Or A-B-B or A-B-A for 3 units.

Even better would be the ability to choose every unit to be a A or B unit so you can have A-B-A-A-B-A or A-A-A consists

I think that is going to be difficult to include with correct front-back behavior if it would be done with random switches. I think alternating front/back B units between the first and last unit is the most simple option, and will work good enough.

Decided to go with repeating ABBA, including visual effects on all A parts.
