Overflows Tutorial for OpenTTD (part 2)

[@undeadnightorc]

I'm coming back to openttd after years of playing Factorio. Watching these overflow tutorials makes me wish Factorio also had a TARDIS-like building that could fit an infinite amount of waiting trains!

[@LugnutsK]

Hmm I wonder if you could make a Factorio mod for that

[@mikeoconnor6410]

Cool 😎

[@projectdust2569]

​@@LugnutsK Well, its not infitine, but you can use train tunnels mod to make underground depot

[@Yvax99]

okay, i hope these series gonna blow up. thanks for the upload!

[@ericfranzen4548]

Hi i have just watched the entire of hellish tutorials playlist but I think you have earned a huge thanks to even though I didn’t understand everything but I will come back later when I have learnt the game more I just started to play 4 days ago

[@lordwunglerbeckett]

at this point OpenTTD is less of a game about moving things and making money, and more like a train and track based programming language not saying that's worse in any capacity tho

[@stewoe7157]

True, honestly I prefer making things look good and realistic and still have a somewhat efficiënt network.

[@jakubiszon6495]

Year 2495 - I thought by this date humanity would invent something better than overflows with reversers, depos and priorities through exit signals, but no, it didn't.

[@Ryan-cy7zw]

It spent all its resources inventing depots that can hold infinite amounts of trains

Great video, keep them coming. I have seen overflow stations using timers, but for the life of me I cannot figure out timers... If timers are not on your list of videos it would be greatly appreciated

[@LugnutsK]

Tiaan Hendriks I’ll definitely do some videos on logic circuits including timers. Personally I’ve never used timers on my overflows. The ABR overflows 2 article has info on it blog.openttdcoop.org/2010/11/07/advanced-building-revue-08-overflows-ii/ but I suspect that’s where you originally saw them

[@Giekeme]

I build the exact same setup as you had at 7:53 but for some reason the trains refuse to go into the overflow. The entry signal is green because the combo signal at the overflow is green, but then they just stack up on one of the red signals going to the waiting bays. I am using the little Y at the end of overflow bay. I have no idea what I am doing wrong. Suggestions?

[@LugnutsK]

Tauntless Make sure the exit signals towards the station are two-way and also make sure you set yapf.rail_firstred_twoway_eol 1. If that isn’t the issue I need a screenshot or save file to help debug (Edit: fix typo)

[@Giekeme]

@@LugnutsK Ah yes, the "set yapf.rail_firstred_twoway_eol 1"... I forget about that one every time I reinstall the game... Damn you for making me install the game again! :P Just for anyone reading this in the future: the command is entered in the command console opened with "~"

[@LugnutsK]

Note you can change that setting at any time, even in-game. Also thanks, fixed that typo

[@Kainore]

@@LugnutsK doesn't seem to work if the station is too large for me for some reason i cut down from 5 to 2 stations and suddenly it works o.O all i did was remove 1 track

[@zazzn]

@lugnutsk at 4:49, what exactly is going on there, you put a signal down but don't say what kind it is. I don't understand when a priority signal ends. I don't know why these priority signals are so damn hard to understand. Nowhere does it ever explain why you need the un traversable track with backward-looking signals and how far backwards they look. Does it look until there is an exit even if there are blocks in between?

[@Kaebuki]

Try watching their priority merger tutorial video, it may help.

[@DaFreak860]

My trains refuse to enter the reverser, it is a bit difficult to explain so please look at 5:44 for this. You can see in at the timestamp how leading to the station, the two exit signals, are red and the one exit signal leading to the reverser is green, and how due to the green exit signal the entry to that block (before the three exit signals) is green as well -- the trains therefore can enter that block, however in my case, the trains entering that block don't enter the green exit signal leading to the reverser, but instead que before the red exit signal leading to the station. I have never seen a train que before a red exit signal before, this is an issue totally new to me so I have not a clue on how to fix it or why it is that it works for you.

[@DaFreak860]

Ok, nvm, I am a moron, I have now placed two way exit signals at my station and now they want to enter the reverser, while I have no understanding why it works with a two exit signal, but it does, and I am still at the copy and paste stage of the game when it comes to learning this, so this is fine, but if you could explain in greater detail, that'd be great.

[@nirasa]

You explained it well. thx

[@sonaruo]

well the way i pass the problem is by making more tracks on the train station usually around 8-10 lanes are enough to handle huge number of trains and a single 2 lines entering existing the station where i prioritize at which lane the trains will try to move in which gives a huge help trains entering stations and entering to not block each other

[@mortenfrosthansen84]

Played this game since that horrible dodgy click mouse, that felt like grabbing a roofing tile.. Only discovered this FIRS mode a couple months ago. It's hard to build these mega hubs, and keep track on every junction. Let alone organise the station inlets. But a question that can work on either grf setting; What I find really hard to perfect is the signals.. where is smart to place, and where is it not useful even though it seems logical? To make sure you don't clog f.ex.. There is a main line station, that is fed by a sub station close by. Is it easier to make a bigger station, with more lines in (space can sometimes be limited for mega stations), but make the sub station route longer? Or like I did, connect it to the main line, as well as possible, to accommodate different goods but at the risk of slowing down the main line..? Sorry think that might be two questions. Thanks for the friendly guides. They are really good... That FIRS setting is a really great idea, and makes the game much more complex. Any starter tips on good secure business?

[@mortenfrosthansen84]

With this overflow, the different use of signals, and the positions is very demanding.. wish you could slow the tempo down by 1,5x. I do get the priority thing, but to link it with all those combo signals.. phew

[@NielsHeinen]

Does this still work with the latest version of OpenTTD ? I have "set yapf.rail_firstred_twoway_eol 1" but the trains just queue in front of the station while the exit signal of the overflow is green. Thanks if you could get back to me on this as I'm super confused as to why it doesn't work

[@EliChampion]

Would it still be wise to build a full-blown overflow system at a strictly drop off industry, specifically power plants, or is there another way you recommend handling high train loads at those stations?

[@RealBenFromCanada]

Came for trains, got caught by ATLA feels, stayed for the nice explanations. I feel both educated and betrayed.

[@LugnutsK]

HMM I knew that song sounded familiar, guess I know now :D. Glad I could betray you!

[@smakarevich]

I made it today, finally.

[@TelfLad]

Is that song what I think it is?

[@JirkaGasik]

Hey, a noob question here - what is with the different colours of the tracks?

[@heralddobre8114]

What is the music ?

[@justpassing6776]

what kind of graphics do you use for stations? those logs piled up looks great

[@LugnutsK]

ISR Industrial Station Renewal

[@AldarisFenrir]

Hi, what mods or grf you use? i used to play ttd when i was a boy. Im giving openttd a try. good tutorials man =)

[@LugnutsK]

AldarisFenrir NUTS trainset is my top choice, has different train classes that add a lot of variety. (eGRVTS or road hog for RVs, AV8 aircraft, and Fish is ships - the other vehicle types, but I mainly stick to trains) Then I always have ISR (industrial station renewal) for eye candy stations. Then later if you want a challenge the FIRS or YETI are custom industry sets that add some interesting and tricky mechanics.

Nice video

[@LugnutsK]

AlexFili's KZbin Thanks!

[@alexlex324]

what graphic mod are you using?

[@benjaminlyderik4390]

Hey, been watching you all your openttd videos, some multiple times. I ran into a problem of train not entering the depot on an overflow. Have two symmetric overflows, one works, one don't, and i can not figure it out. prnt.sc/w1ww05

[@prawtism]

Crazy complexity, did you invent half of that stuff? :D

[@prawtism]

Lool, just when I commented, I continued watching and you started talking about how some people would say it's the craziest overengineered waste of space ever :D:D

[@LugnutsK]

@@prawtism I wasn't the first to build any of these designs. Though I have made a few original overflow designs, these ones are the bread & butter.

[@julianbailey2749]

In a world with TARDIS technology train storage sheds, but no conveyer belts, weird shit happens.

[@GenericInternetter]

Impressive but you didn't explain the signals in either video

[@ivanb2907]

OpenTTD - a game for grown up males who's inner child loves trains

[@mikej2489]

i am 26 and cried over that song when i watched the avatar series. God that feels.

[@ThorRuneHansen]

et yapf.rail_firstred_twoway_eol 1 There, for those like me who came back trying to find what that command was :)

[@UntouchedWagons]

My brain hurts!

[@sunofabeach9424]

holy shit

[@wieszos]

it's a shame that all these designs look so ugly, especially with "priority" lanes that go on and off

[@linuxgaming69]

Nope. Didn't understand that at all.

[@LugnutsK]

It's pretty wild stuff, not really possible to figure out just by watching a couple short videos. Best way to learn is to play and see what works, and hopefully the video can help explain why trains do what they do

[@linuxgaming69]

I've played OTTD quite a lot but I end up just making trains queue. I like the idea of forcing them into the depot while they're doing nothing else. I'll have to experiment!

[@zunkman1]

So this is really confusing. So why don't you just show the end result so that we don't have to see the first 14 ways that don't work. So your video would be shorter and so much more understandable.

[@Cruz0e]

I don't think any1 can follow this :)

[@ZeeKee_CzeCza]

I was looking for that comment, I can't understand how it works at all xD
