That would be great!

Shouldn't you ask that in the CPP thread? As that has nothing to do with YACD development...

I get "out of memory" errors trying to load games from nightly OpenTTD, it is always attempted to allocate 4294967295 bytes no matter how small the map is. The ancient trunk intro game works.

I ran OpenTTD in debug mode, and it seems to happen when loading industries (INDY chunk).

I've succeeded in going from "out of memory" to "invalid chunk size", and everything from 1.1.3 works, so not that big of a deal. But there's still a nice crash right in the main menu when in debug mode (-d 4)... need to check it out a bit more.

Been looking back through the thread, and didn't find the answer; if I missed it, I apologize.

I started a line hauling iron ore to a steel mill by rail, then used trucks to feed wood and coal to that station for distribution beyond the steel mill. For some reason the trucks load up at the source, partially unload at the railhead, then haul cargo back. Eventually they get full of cargo that they won't unload. (Will post a screen shot later.) I wasn't using any transfer or load orders. I tried to fix this situation by using "unload and no load" at the railhead, but the trucks ignored this order. Any suggestions?

please post a savegame and state the exact version you are using.

Checked again, it's a desync error with the "StationCargoList" cache.

Here's the updated patch (r22944) anyhow...

Since I was wondering about current status I searched the IRC logs and came across the following:

2011-10-17 21:20:28 <+michi_cc> Elukka: YACD is waiting on some inspiration on how to make the algorithms at least twice as fast (or for somebody to rewrite the core game loop with multi-core support).
2011-10-17 21:26:01 <+michi_cc> YACD speed is directly related to number of active cargo packets and number of cargo producers (which in practice means house count, in comparison those few industries don't really matter).
2011-10-17 21:29:40 <+michi_cc> Terkhen: Most of the YACD cargo pathfinding could be done parallel if the events that modify link graph woudn't be all over the place. This especially means vehicle movement where movement, stopping, loading/unloading is all done serially on each vehicle instead of first moving all vehicles, then checking station state, then loading etc.

Posted it here since maybe there's inspiration in the development forum , and clarification for other people not on IRC.

Started playing with YACD and really like the idea, but so far I've failed to find a way to make any kind of transport system oay for its self.

I start my games in 1830, and so far trying to run passenger services has turned out to be a bust as there are never the numbers of passengers to make any system work. At best I might get 20 passengers to move in a month even from one large town to another.

It's a similar story with any industry, as none produce enough to make the system carrying them viable.

Any ideas, hints tips, or settings I may have messed up.


Cheers for any info.

Glenn.

It's very hard in 1830 You need good RVs and there aren't any.

At the start of a YACD game, you need to find a cluster of towns where the passengers want to travel mostly in the cluster.

Then spend all your cash connecting them as completely as possible, as cheaply as possible. You need to cover as much of each town as possible to get the maximum coverage of destinations. Get as many passengers onto the network as possible and then let YACD work its routing magic.

Don't waste cash at the early stage on *separate* networks or point-to-point lines. Just connect one network really intensively, mostly with cheap trams or buses.

Thanks for the advise.

I'll give that a try tonight.

Question... anyone know of any public servers running YACD? I know some running CargoDist, but I've found I vastly prefer YACD, with its predetermined destinations.

The trouble seems to be that patchpacks all seem to include CargoDist instead of YACD.

Sorry to double post, but I've been playing this more, and noticing that while it works fine for passengers, other kinds of cargo... don't seem to work properly. By that I mean, vehicles will suddenly stop loading cargo at all. I've found it's particularly repeatable with situations where cargo must be transferred between multiple vehicles... oil by train to a dock, picked up by ship for example. The ship, after the 2nd or 3rd load, will simply wait at the dock forever while the train keeps depositing more and more oil. The oil states it is headed for the ship's destination, but it never gets picked up, and with a "Full Load" order, the ship just stays at dock doing nothing.

Is this a known issue?

Is there any plan on introducing a cargo reduction parameter? I have played 20 game years and some of my pax stations are already overloaded and I really can`t put more trains on my network anymore.

There is a patch floating around this forum and also a NewGRF, to which I cannot find a link somehow... it's called townpassmail.grf and I believe it was based on the EarlyHouses NewGRF.

This is not a problem of YACD, but of OpenTTD in a more general sense.
It should be solved independently.

Might be, but it is not a problem in normal OTTD games without pax destination, as all trains take all available cargo. But with the change of that logic, the generated cargo is in no relation to the possible services any longer. Therefore, it should be part of the patch introducing the destination that corresponding reductions can be done. Cargodist has it, and so does the old cargodest patch.

The Irish wrote:Cargodist has it, and so does the old cargodest patch.

actually no. it has always been a separate patch. never been part of any cargod*st.

you`re right. sorry about that. Still don`t see a reason for not including it in this patch, though.

Simply because destination/distribution of cargo is a totally different concept than reducing the amount of cargo being generated.

Commits to trunk are never a combination of two features and even larger patches are split up in smaller commits.

I'm new to the game so I apologise if this has been asked before. I notice that NoAI integration is still a todo item according to the first post... does this mean that none of the current AIs know how to deal with cargo destinations? I'm trying my first game with this patch and all the AIs seem to be stagnating or going bankrupt because they are building very unprofitable passenger routes... routes that probably would have been profitable in the base game since they are in big towns.
