Mop Generic NRT Road Vehicle Development (was Trolleybi)

[Emperor Jake]

Hi, not sure if you're aware but this set somehow causes desyncs in multiplayer games when certain tram vehicles are built. Known affected vehicles so far include Kaimuki Articulated Electric Tram and Yarra Electric Light Rail Vehicle. Possibly other articulated trams, non-articulated ones didn't seem to pose a problem. I haven't tested this further but the server's desync output might help. If needed I can PM you the savegame and needed GRFs.

Whoa, I must be in way over my head, not sure what I messed up to cause desyncs! I have not touched this in over a year but I do still dearly want to keep working on it. I imagine it's going to take a lot of IRC time to figure out what is going on, but many of the trams have non-deterministic liveries so maybe that is part of the issue?

Can we have articulated open trucks in the next release (as and when)? There are only open ridgids available and and open RVs are the only ones that can carry plant fibres in FIRS 3. So it's either ridgids or trams, it kinda limits our options.
Great set!

The open trucks are my favorite, but I always sort of saw them as the expedient/backcountry/developing world runabout rather than a proper specialized truck (I even wanted them to be refittable to passengers). The idea was less capacity but greater flexibility. I never got around to open trailers when expanding to semi-trucks as they seemed redundant and lacking a compelling prototype, but I must have missed that plant fibers were un-served. Is there a truck bed type that seems better suited to plant fibers? If I have to make 4-12 new trucks anyway, they might as well be something more interesting!

[Diesel Power]

Plant fibres in the covered hopper (shredded maize) or Flat trucks (straw bales) would suit best. speaking of which... I'm getting some strange graphical glitches on some of the trucks. Seems to mainly affect the covered hoppers. I'm using JGR PP 0.32 rc5

Hello!

I upgraded from the version of RATT I was using to OpenTTD nightly, since it now support RATT.
And I run into an issue with trolleybus/trolley vehicles, as they does not appears in-game.

Other vehicles appears in game fine, along with ratt-modified HEQS and Road Hog vehicles, so I know that the RATT specific functionnalities are working.
Am I missing something?
I tried this with OpenTTD nightly 20190908 and the more recent, 20191011. Same thing either way, so I have to assume it's on my end.
Is there something specific like a NewGRF for trolley roads I need to add, or an option in-game?
The electric road vehicles are activated in-game (in the MOP GRF options at least).
I use Country Roads and SUV, but even with both those NewGRF disabled (had to try in case they were causing weird conflicts) trolley vehicles and roads still doesn't appears.
I added the RATT roads NewGRF but still no luck.

I'm not sure this is the best place to ask, but I'll gladly take my question to a better topic if pointed to me.

Yes, you need to use a NewGRF road set that that support electrified road vehicles. IIRC right now that is only Docklands, found here: viewtopic.php?f=67&t=75941

[Lesarthois]

Oh, that was the missing link
As I said, I upgraded from RATT to nightlies about last week and at first I didn't noticed the lack of electrobusses.
Perfect Dockland as a bit too much roads for my tastes, but better than nothing

[Emperor Jake]

There is also Unspooled and U&RATT

[Lesarthois]

More choices, good to know

[Diesel Power]

I've spotted a gap in the roster. The piece goods road train between the Tama and the Du Nord is missing.

[JGR]

Are the sources for this GRF available (in particular 0.6.5)?
This GRF appears to be doing something unusual and It would be useful to see what the intended behaviour is.

The GRF (I've only tested 0.6.5) changes the value of the custom cargo ageing period (RV property 22 via callback 36) depending on how full the vehicle is (vehicle variables BA and BC).
I haven't found anything in the spec which explicitly states that this is not allowed, but it is highly inadvisable as it will cause desyncs and so makes the GRF unsuitable for any sort of multiplayer use.

[Emperor Jake]

Ahh that would explain it! That's why the affected trams can work without problems for a while before the desyncs start. For the record we havent' had any further problems with this set simply by not building any articulated passenger trams (which is a shame because they do look nice)

[Gadg8eer]

Found a bug in the fourth-gen covered hopper trucks:

[supermop]

This new update removes cargo aging-by-load percentage and replaces it with a fixed parameter, as apparently this feature was causing desyncs. I am not exactly sure why, as the changes were deterministic, and it doesn't seem like NewGRFs should be able to cause desyncs at all. Nevertheless, it seemed safest to remove it.

This update does not fix sprite alignment issues with covered hopper and livestock trucks, as it is going to take me more time to figure out what is going wrong with those.

Hello,

A new update, 0.6.7 is available now on Bananas. This update fixed the broken covered hopper trailer sprites, and adds a few other small changes.

Best,
