(´・ω・`)MERRY SOMETHING! Ranran is here to deliver a livery patch.
If I am trying to paint a bus, why are hovertravel and ffestinog railway options?
I was very empathize with it. So now I made a patch trying to solve this issue.
1. Enable to define waytype attribute for the livery scheme in the livery description of simuconf.tab.
ex)
livery_scheme[0] = British-Railways
livery_scheme_wt[0] = track
If nothing is described, all waytypes are assumed.
Is livery_scheme_waytype preferred?
2. Only the livery scheme of the waytype that matches the depot is listed in the livery scheme selector on the depot dialog.
There is no change in the cumbersome livery scheme selector in the line management dialog. IMO, it is a different task. That is, improvement of the line management dialog.
Prissi suggested tabbing the right side of the linemanagement dialog, I thought it would be a good idea.
There is no connection between the station and the livery but it is closely related to the convoy list, so I think it is better to place the livery selector on the right, but currently there is not enough space on the right.
Different waytypes cannot be specified at the same time. If you want to represent a real company that operates multiple waytypes, do not define a waytype or duplicate the livery scheme and define a different waytype. Then the livery scheme list in the line management dialog is a little contaminated, but that would be insignificant.
Well, for this feature to work perfectly, the pakset author needs to define a waytype for the livery scheme.
Unfortunately, the only British transportation companies I know of are LNER and ScotRail. (´ ・ ω ・ `)
But for now, I classified and entered a temporary waytype value and uploaded it to
my repository. You can use it to test this feature.
Note that some livery schemes have multiple waytypes, so they are not currently set to anything. (First-Group, Sheffield and WMPTE etc.) They are displayed in all depots.
However, as mentioned above, it is possible to duplicate a copy and specify a different waytype.
I split the L&BR into two for testing and assigned track and narrowgauge_track. So L&BR will not appear in the bus depot, but there will be two L&BRs in the non-clickable list of the linemanagement dialog.
Demo image:In the example of
1951, the current version shows a lot of choices in any waytype depot.

This patch makes the list healthy like these.
Rail depot:
 | Road depot:
 | Ship depot:
 | Air depot:
 |
Note: The ones displayed in all depots have no defined waytype.
Again, I am not familiar with transport company in the UK, so
it needs to be confirmed the waytype settings in
simuconf.tab.
I may have overlooked a scheme that has multiple waytypes or one waytype now but another waytype may be added in the future.
BTW, regardless of this patch, I found the number incorrectly, so the following needs to be fixed even if this patch is not accepted.
- livery[100][0] = L&BR-Standard
+ livery[101][0] = L&BR-Standard

Thank you. (´・ω・`)
