Helper to Train, Train to Helper

Post by **PikkaBird** » 17 Jun 2006 01:55

I've mentioned this a few times in chat, but I reckon I should probably post about it here too, just to get some popular support (if there is any

).

OTTD can currently do this. Wouldn't it be great to be able to do it in TTDP too?

I reckon all the only value that would need to be copied across is the age of the locomotive, and possibly the random bits for sprite selection if people think that's worth it. Otherwise, it's just a case of deleting the train loco and rebuilding it as a "wagon", and vice versa.

What m3henry said. Presumably it meant agreement.

I would love to see such a feature.

I'm often trying to save some of the older engines and use them in new consists as helpers or so, which currently is only possible if you rebuild the old engine, which in many cases, leads to different livery or so.

So I would really love to see such a feature in the Patch.

Yeah it would be a great feature! Would add some realism as well.

I like this idea too, but dunno what's involved Patch-wise. It's been asked before.

It is a good idea, sometimes I dont want the expense of selling an old loco for £255 and having to fork out, what can sometimes be hundreds of thousands of pounds for a new one!

I am confused.
Is the idea to refurbish a locomotive and change its age to brand new

No, AFAICT, the idea is to be able to switch a loco between being a seperate train and being one of the X amount of locos in a train, simply be dragging it like you drag wagons, in the depot menu. Keeping age of course.

This idea would be great. But as krtaylor said, dunno what's involved patch-wise. I guess if this was easy, it already would have been implemented.

Actually, as I think about it, I asked about it before, a long time ago, and Patchman said it would be prohibitively hard for the relatively low benefit. It's possible Patch technology has improved in that area since then. However, as we see he is not posting in this thread, I deduce that it hasn't, and that it isn't going to happen.

Well, I don't see how this could be any harder than, say, clonetrain.

Ah yes, I've been wanting this feature for ages too - mostly for the reasons The_Irish stated...

Really, in the DBXL, when your freight trains need mutli-heading, currently the only "realistic" way to do this is to attach a new train to an old one... But then, it doesn't start the clock ticking on the newly built train, just keeps ticking away at the old one...

Hmm, hard to explain.

Still, good idea.

I know exactly what you mean. And it is not only valid for the DBXL...

Bit of a proof of concept, saved game hacks.
TRT00.SV1 is the orginal and TRT01.SV1 the hacked version.

I have spent about 20 minutes on this, creating a master list of variables which need changing etc.
And then applying the changes to my test saved game.

If you look at them, you should see Train 3 was convertted to an extra head.
I'm unsure if there was extra data I needed to set though, so there might be bugs with it (TRT01.SV1).

It should be possible to expand the concept to TTDpatch.
Although, I don't have the time too look into it too much though, sorry.

In one of the upcoming nightlies there should be a very experimental version of this.
While, I've got most crashes and bugs out of it, it is possible some settings which may cause a crash.

First you will need active a new experimentalfeatures bit for it.
Then move a train engine holding control, this train must have no consist attached to it.
This might be over come in future versions but currently, it doesn't accept them.

It should remove the orders and such and move the to the location spified.

Reverting them on the other hand would be very difficult.

So please don't ask for it reverting, it might be done in later versions but for now, you got what you wantted?

[edit] Cannot commit it now though, thunder storm coming.

Fantastic! Another thing to add to the ultimate brilliance of the TTDPatch Devs!

As of the next nightly there should be a fully working convert train to multihead unit.
It should handle having a consit attached to the vehicle, or being convertted and 'dumped' on a blank line.

Click and move the selected unit whilist holding ctrl, it should be converted into an extra head.

There is no code for the process to go the other way.
You cannot make an extra head an engine with the current code.
