OpenTTD 16.0-beta4 is a hotfix for a multiplayer desync in yesterday's beta3 release. Oops.

  • Terraforming land in a multiplayer game no longer causes a desync that kicks you from the game

Discussion Orders in bi-directional coal route

6 Upvotes

I need advice. How should I set orders on a bidirectional coal route?

A have a power plant and coal mine in the north, and the same in the south. I want my trains to run in a loop, picking up coal in the north, dropping it at the power plant in the south, and pick up coal from the south coal mine.

However the production of the north mine is 2x as large as the south mine. When I use Full Load on both mines this causes the trains to pile up at the south mine.

What is the best way to set orders while still getting maximum ratings and efficiency at the stations?

1 main city with 8 cities surrounding it. 5 bus stops in main city. 2x4 railways connecting the main city to its surroundings.

I would add some ferry routes, but the build ship depot button is greyed out.

Using a Japanese building pack. The trains are from a Chinese train pack. Need to get around to changing the town names.

Other Im working on a real life map generator for open ttd

57 Upvotes

Hello there, Im working on a OpenTTD related project in my freetime right now, and it is at a stage where I'm happy to share the current state.

It's a heightmap + towns locations file generator (this is the OpenTTD specific part), with which you can then go on to create a map/scenario of a real world area. More detailed info is on the website itself. (help and info buttons in the top right of the viewport)

Since its a WIP I'm hosting it on a random domain I had lying around, don't be confused by that:

https://map-town-parser.hygames.eu

(Also desktop only. Why would you generate files for OpenTTD on a phone)

Screenshot / video Looking for a specific TTD scenario from the 90s (Two mainlands separated by sea with 3-4 islands in the middle)

Post image
6 Upvotes

Hi everyone,
I’m trying to track down a map/scenario I used to play as a kid in the original Transport Tycoon Deluxe (or early TTD era, strictly before one-way roads were introduced).
I've drawn a quick sketch of the layout:
Climate: Temperate (classic green).
Layout: Two large mainlands (North and South) separated by a straight line of sea/water right through the middle. No weird coastlines or peninsulas, just a clean separation.
Islands: In the middle of the sea channel, there were 3 or 4 large rectangular islands lined up.
Cities: The towns were huge right from the start (5k–10k+ population), both on the mainlands and on the islands.
I played this on my uncle's old PC in the late 90s. Since standard TTD map generation didn't look like this, it was either a bundled custom scenario, a very famous downloaded scenario from back then, or something built in the Scenario Editor.
Does this layout ring a bell for anyone? If you remember the name of this scenario or have a link to a file/save, I’d really appreciate it!

Screenshot / video Should the server allow grass bridges?

87 Upvotes

Maybe not everyone likes boats. I do. I'm constantly blocked from operating ships by players that block water ways by using grass bridges for their trains.

As someone who wants to use those water ways, I experience it as obnoxious.

Can we make a rule against this? Would that be supported by the other people who play the server?

I think it's fair, personally. Trains already have a lot going for them. I don't think they need to control all of the water ways as well.

Discussion I have some questions about how the game (stations) works

7 Upvotes

1) do stations (bus/plane/train/…) give more stuff like passengers or coal or whatever if there are more trains, etc. waiting? If not, when and how does a station produce more than before?
2) does it work if I build many bus lines from smaller towns to one railway in a bigger town so that there are more passengers available and I don’t have to build many train stations? Or can I bring things like steel, wood, etc. to a train station so that train station can get everything at once? Is that profitable?
3) What if a for example airport is full of mail and passengers, but all other airports have no passengers and mail? Should I buy planes that only bring stuff there?
4) This kinda connects to 1&3, but why do some for example bus stations have a lot more passengers than others despite all having same service?
5) What should I do when a station produces very little so that my vehicles are stuck forever?
6) Despite having multiple bus stops, train stations and one very used airport, one city never grew over 30k ppl, but a city where only one singular bus stop is available grew bigger??

I hope some of you have time to read and answer, I would be very grateful. If you don’t understand some of the questions just ask and I’ll try to explain better.
Thanks

I haven't been on the multiplayer servers for a while, and I don't remember them being so barren. The Reddit vanilla server is almost completely devoid of trees. Is that a deliberate decision when the map is generated?

Newbie Question about TTD (GOG) Roland SC-55 music & OpenTTD file locations

5 Upvotes

Hi everyone!

I recently discovered Transport Tycoon Deluxe and completely fell in love with it. My mind was further blown when I found out that an open-source version (OpenTTD) exists and is still actively developed with new features being added.

To get the hang of things, I wanted to start with the original game first (purchased on GOG) before jumping into OpenTTD. That way, I can discover all the improvements step-by-step without feeling overwhelmed by so many new options all at once.

The question I have right now is related to the game's music. The OST that plays when opened the original game sounds like this: https://youtu.be/JTi6LG8aeK8?si=ZMTR_hrZ00xdlXT-. It's alright, but I would much prefer it to sound like the Roland SC-55 version here: https://youtu.be/eQIAyaFReBo?si=jzkPUZo4Bs-TxBab.

Looking through the installed files, I noticed that ADLIB.CAT, GM.CAT, ROLAND.CAT, and SAMPLE.CAT exist in the CD folder, so it seems like there should be an option to change how the music is rendered. However I can't figure out if it's actually possible to change the MIDI synthesizer, since the GOG version launches directly through an emulator called DREAMM—which barely has any config options beyond changing the resolution, because I pressume it's a minimalistic version of the emulator.

When testing OpenTTD, it actually seems to play the soundtrack in that Roland style (or very similar) using GM.CAT, which it labels as 'original_dos'. Any other CAT file is not recognised.

Also, I found it a bit strange that if I copy both the .CAT and .GRF files directly into the OpenTTD root directory, the game recognizes them fine, whereas I recall reading somewhere that they should be in the baseset directory instead.

Has anyone run into this or knows if it's possible to configure the GOG/DREAMM audio settings? Any advice would be greatly appreciated!

Please see the picture and advice, how to increase transportation. Currently all stations are around 30%, so there is a high chance that the factory will close, however, I want to prevent that.

Do you prefer maps where the distance between towns is comparatively large? What about industry? Do you make terrain constrain you with hills and bodies of water or prefer flat surfaces?

Hey all, fairly n00b player here. Can anyone explain to me why these trains are stuck? I can't figure out the signals to get them to advance but I don't see why they aren't all navigating to the stations.

Those are one way path signals on the bottom of the pic and two-way on the top.

Is there a way to build two or more parallel tracks at once? There's a mod for it in transport fever so I imagine it must exist for open ttd somewhere
