[OTTD] 2cc TrainsInNML

So, what can I do to help? How do you want them realigned? What offset should be for shorter engines?

FWIW, these days I use the same offsets for long vehicles as for short vehicles, and just shorten the sprites from the back. It's much simpler than having different templates and offsets for each length!

From all this, it seems we've (read: mostly me) made quite a mess...

I'll need to check how I want to have them realigned, before I let you do something that should then be done different again.

How do you mean? You have one template with code, and just move the sprites inside their graphics file? That is also what we are trying to get here.

Spritesheet layouts are such a PITA. I'm half considering writing code to deal with them.

Assuming there's a gap between each blue box (and that all the angles are consistent), it wouldn't be hard to detect the blue box, then crop inside it to the extent of the vehicle, then reposition it to a correct location point, using the lower part of the vehicle as a baseline. There would be some error rate on edge cases, but not that high I think.

I could probably figure this out with a bit of time. Meanwhile Eddi could likely do it in no time whilst standing on his head with one hand tied behind his back. Not that I'm volunteering him...

The graphics keep the same order as the other 8/8 MUs and doesn't need additional code. Only the location in the blue boxes are changed. I think that is less work than the re-arrangement you propose.

That would work too. Only thing is it makes the templating system slightly harder to remember for the artists (moot point with this set, as it's already drawn?)

No moot point there. The 2ccSet has been expanded a few times in the past, and it's set up in a way that allows for many more expansions. There's not really a limit here, just need someone to draw the sprites and someone to edit the code

Sounds like a useful tool. Would a bow-emoticon convince you to give it a try?

I think the largest mess comes from my part, as I code MUs different than the old set. The old set used the last MU-wagon in a chain as back and not reversed, but I make it a dual-headed engine and set the graphics using var[0xC8] (and thus a reversed part), resulting in the problems.

Regarding realignment: For front engines, tenders, articulated parts and carriages the alignment is like you described here, for the reversed parts like the back of MUs I want it different:
#1: Bottom
#2: Bottom left
#3: Bottom left
#4: Bottom left + 1px up for each 1/8 shorter train
#5: Top
#6: Bottom right + 1 px up for each 1/8 shorter train
#7: Bottom right
#8: Bottom right

Attached is the Greece Thessaloniki to demonstrate it, it is a 6/8 vehicle.

Before you start spitting through all your sprites, I'll correct them for all metros to test if those alignments are really correct and I've not made a mistake.

Yeah, basically like this:

The shortened tender is drawn on the same template and uses the same offsets, it's just shortened from the back.

... realignment...

I understand. I'll prepare for eventual work by browsing trough all MUs and single out all those shorter than 8/8. Just to be prepared if you require realignments.

BTW, you don't require the rear engine to be reversed any more, do you?



EDIT: OK, done. I have 5 MUs shorter than 8/8 - AGV, AGV Duplex, Eurostar, M131 and S-to IV. However... AGVs and the Eurostar are "special" cases, these will certainly need a separate coding process... (AGV as example below)...

Indeed, they don't need to be reversed. That is all taken care of on the code side.

Only 5 MUs, that is manageable. Are those only the MUs that you have drawn, or all MUs?

Also good to know that those are "special" cases, I already noticed that there would be some when I was browsing through the sprites.

Only mine but (not intention to brag at all) almost 90% of the vehicles in the set are my work so...

Yes, the AGVs and the Eurostar have a special 2nd and second-to-last car. Also, SOME MUs have additional wagons. The example is the Odakyu 10000 below, with additional coaches with pantographs. The idea is that most wagons DON'T have pantos but at least one does for sure and more *could* have pantos but that is randomly determined (a VERY small chance, IIRC 5-10%).

I just uploaded the changes with the re-arranged sprites as described here, I think this arrangement works, please test if they are correct.

Okay, that is going to be a lot of fun to code correctly, and won't go as nicely with the script I have been using to code the metros, but I can still use that as a base and then manually modify what is needed.

[PikkaBird]

Why random? Surely a regular pattern would be a better option?

Yes, the AGVs and the Eurostar have a special 2nd and second-to-last car.

For the sake of completeness, you should probably also include a sprite for a car which is both the second and the second-to-last (ie, the middle car of a three-car train), no?

That was DJ's idea and I agreed with, however I don't mind making it differently.

There already is that sprite. Take a look at the AGV picture I've posted just a few posts back, it has the "2nd & last pax wagon" and "2nd & last mail wagon".

... ah yes, the initial idea of this set is that all MUs can be refitted to mail/valuables/similar...

There are several options there. Random (with one fixed), regular pattern, only powered wagons. I think a regular pattern would look best, or just one single panto.

I think PikkaBird meant a wagon that is graphically correct for trains that just have one wagon. Personally I don't think such a wagon is necessary, as the graphical error is very small and I think most people wouldn't notice it.

A-ha, I understand. Well, if I see it right on the AGV example, it should be an easy job to do.

Something like this?

[Transportman]

And that is another bunch of vehicles included. With the inclusion of the Diesel railbuses in r44, all railbuses* should now be in the set.

Indeed, something like that. The alignments for the vertical views looks different when I compare it with what I posted earlier, the first sprite in each row should be aligned to the top of the box and the fifth sprite to the bottom, instead of bottom and top.

*All railbuses included in this list.

Awesome

[Voyager One]

A-ha, OK. Understood.

Except for trains with a shortened reversed last unit, there the alignments are different. So if there are MUs with a short nose, the back nose should have a different alignment. The rest should all have the alignment you described here. Might need to check all vehicles, had enough diesel railbuses that also were aligned differently.

[Voyager One]

In reality, MOST my engines have their 1st sprite aligned to the bottom and the 5th sprite aligned to the top. That was the variant agreed with DJ. Meaning I'll have to realign thousands of sprites, we didn't even talk wagons yet...

So, some sprites are aligned 1st top and 5th bottom and other sprites the other way around? Do you have an estimate how many engines and wagons might be affected? If it is really a large number, I can look at using a different code template for those or we can split the work if it is a smaller (but still large) number.
