assuming you're changing the price of them as well?

iron rampart Dec 14, 2024, 10:40 PM

#

Yeah

underground belts consume transport belts

balmy charm Dec 14, 2024, 11:01 PM

#

nicely done

#

i've got a very similar project (like almost 1:1) in the pipeline but its nowhere near as complete

iron rampart Dec 14, 2024, 11:31 PM

#

Don't worry. This is also very far from finished

#

I would appreciate any help. I actually got a migrane from making this

balmy charm Dec 15, 2024, 2:04 AM

#

my version has been for underground pipes, so its probably not as appliccable

iron rampart Dec 15, 2024, 2:16 AM

#

I also wanted to do underground pipes in my mod as well, but i am not sure how

#

also underground pipes are pretty cheap anyway so im not sure if it really matters

balmy charm Dec 15, 2024, 3:10 AM

#

i had a few ideas for my overhaul that will probably differentiate our mods

#

i was gonna try for both pipes and belts (undergrounds) have a way for bots to make the undergrounds (like from blueprints) and have it so that when you research new levels of tech like logistics 2 that add longer range undergrounds, you can then use previous tiers of undergrounds at those ranges

that is interesting

iron rampart Dec 15, 2024, 6:42 AM

#

is changing underground belt length with research even possible?

#

i think you would have to generate new items on startup for that to work.

#

i plan on making my mod as unnoticeable as possible, so you can still blueprint your designs and use them in a vanilla save. I feel it would be best to have an optional config for underground belt distance.

balmy charm Dec 15, 2024, 7:25 PM

#

yeah, which is why i think ours will be different

#

its not possible to change with research, but it'd be doable with separate items per research

iron rampart Dec 16, 2024, 8:11 AM

#

#

spent way too long on this floating text

balmy charm Jan 12, 2025, 5:17 PM

#

i just realized that i need to rework my entire project... this is going nowhere 😦

#

i also figure that there is no decent way to disable the underground belts while keeping them "connected"

balmy charm Jan 12, 2025, 5:49 PM

#

@iron rampart are you disabling the undergrounds if they are placed without sufficient belts to connect them?

iron rampart Jan 12, 2025, 8:24 PM

#

Yeah, that was the idea, but it's kinda not possible

#

The only way I found to disable the underground belts is to replace them with an identical item that just has 0 speed, but this causes too many problems

#

I gave up on my mod because it won't be possible unless the devs add a way to disable underground belts with a script. They probably won't though because of the way they work

#

I can make my mod work if I don't disable the underground belts, but then the whole requiring belts thing becomes merely a suggestion

#

I suppose that is good enough?

balmy charm Jan 12, 2025, 9:48 PM

#

i guess

#

i think maybe i can replace them with identical linked belts but idk

balmy charm Jan 12, 2025, 10:31 PM

#

i think for now i'll work on the pipes, for those at least i can just have it replace with an identical pipe that doesn't allow fluid flow

iron rampart Jan 12, 2025, 10:41 PM

#

balmy charm i think for now i'll work on the pipes, for those at least i can just have it re...

What mod are you making again?

#

Keep in mind that undergrounds can only connect to other undergrounds with the same prototype

balmy charm Jan 12, 2025, 10:54 PM

#

same thing but i was gonna do pipes first

balmy charm Jan 12, 2025, 10:56 PM

#

iron rampart Keep in mind that undergrounds can only connect to other undergrounds with the s...

not for pipes, they connect to everything unless you specify otherwise

balmy charm May 25, 2025, 5:01 AM

#

hey, hows the mod going?

iron rampart Feb 28, 2026, 1:47 PM

#

balmy charm hey, hows the mod going?

Hey, sorry for the late reply. Basically, I hit a wall and gave up shortly after the last post

#

I recently got back into factorio and decided to give it another shot, this time taking a simpler approach.

#

I got a bare minimum version working well enough to be stable for actual gameplay I think

#

The upgrade planner still gives me trouble though. It sometimes deletes a few belts, but it's hardly noticeable when I usually walk around with a thousand

#

I know you are making something similar with pipes. It might be interesting to compare our different implementations

balmy charm Feb 28, 2026, 1:56 PM

#

no worries. my version is similarly dead in the water. it needs a (fourth? fifth?) rewrite, i dont know if ill end up doing that. also not sure if it'll get ported to 2.1

balmy charm Feb 28, 2026, 1:57 PM

something something hotswapping entities like hotcakes and a load of bot based jank

#

i have a better idea but it requires that full rewrite so, here we are :)

iron rampart Feb 28, 2026, 1:58 PM

#

Yeah I gave up on the swapping entities

balmy charm Feb 28, 2026, 1:58 PM

#

https://github.com/protocol-1903/piecewise-undergrounds

iron rampart Feb 28, 2026, 1:59 PM

#

I already read a little bit of it

#

Idk how it works lol

balmy charm Feb 28, 2026, 1:59 PM

#

the suggestion i got, which was a really good idea, is just cancelling placement if you dont have enough belts/pipes to connect the two

iron rampart Feb 28, 2026, 1:59 PM

iron rampart Feb 28, 2026, 1:59 PM

#

balmy charm the suggestion i got, which was a really good idea, is just cancelling placement...

Is this possible?

balmy charm Feb 28, 2026, 1:59 PM

#

yeah you just delete the entity and give the player back the item

iron rampart Feb 28, 2026, 2:00 PM

#

Lmao alright then

balmy charm Feb 28, 2026, 2:00 PM

#

the trick then becomes just handling when bots do things

iron rampart Feb 28, 2026, 2:00 PM

#

I decided to reduce the complexity as much as possible and that was how I got it actually finished lol

balmy charm Feb 28, 2026, 2:01 PM

#

the other problem i ran into was quality just screwing everything over

iron rampart Feb 28, 2026, 2:01 PM

#

I straight up didn't account for quality

#

What lunatic uses quality pipes

#

Or belts

balmy charm Feb 28, 2026, 2:02 PM

#

so at that point i gave up and printed a warning to chat saying 'ay bro it dont work with quality dont report bugs cause i aint fixing them'

#

beats me

#

some shmuck gonna do it anyway

iron rampart Feb 28, 2026, 2:02 PM

#

I gave up on trying to stop underground belts that were missing belts

balmy charm Feb 28, 2026, 2:02 PM

#

lol

iron rampart Feb 28, 2026, 2:03 PM

#

It's a trust based system now ✨

#

There is legit nothing stopping you from placing underground belts even when you run out of transport belts

#

But, when you get bots they will try to place them

balmy charm Feb 28, 2026, 2:03 PM

#

yea

#

pipes at least i can get around by doing funky connections

#

belts are... just annyoing

#

still wish you could disable splitters and undergrounds. like cmon, you can freeze them but not turn them off? seriously?

iron rampart Feb 28, 2026, 2:04 PM

#

I was thinking about adding support for pipes with my mod. I probably could do it, but I wonder if I should?

iron rampart Feb 28, 2026, 2:04 PM

#

Is there a freezing script? Lol

balmy charm Feb 28, 2026, 2:05 PM

#

i dont see why not. i wouldnt mind a ~~competing~~ better mod lol

balmy charm Feb 28, 2026, 2:05 PM

#

iron rampart Is there a freezing script? Lol

i wish smh

iron rampart Feb 28, 2026, 2:05 PM

#

I just don't wanna do work I don't have to do. If your mod works already

#

An also like. Underground pipes are dirt cheap

balmy charm Feb 28, 2026, 2:06 PM

#

fr

#

maybe not modded but eh

balmy charm Feb 28, 2026, 2:07 PM

#

iron rampart I just don't wanna do work I don't have to do. If your mod works already

works with the fat asterisk that you don't do anything too crazy 😅

iron rampart Feb 28, 2026, 2:07 PM

#

I feel that lmao

balmy charm Feb 28, 2026, 2:07 PM

#

i might get around to rebuilding it eventually. ive been doing too much pipe shenanigans recently im pretty done with fluid shit

iron rampart Feb 28, 2026, 2:07 PM

#

When I was testing I was playing like a total idiot

#

I had multiple beltweaves that I was combing over with my upgrade planner

#

I kept doing that until I got to the point where it didn't crash anymore

#

It's not perfect, but if you experience a bug it's probably because you are playing wrong

iron rampart Feb 28, 2026, 2:10 PM

How did you do the real underground pipe mod?

#

That's way cooler than what I did lol

#

I want to do bendy underground belts

balmy charm Feb 28, 2026, 2:11 PM

#

actual underground pipes or piecewise undergrounds

iron rampart Feb 28, 2026, 2:11 PM

#

The bendy one

balmy charm Feb 28, 2026, 2:11 PM

#

iron rampart I want to do bendy underground belts

gonna be doin that eventually
-# fuck dont remind me

iron rampart Feb 28, 2026, 2:12 PM

#

How would that even work. Do you need to make a new surface and use linked belts?

balmy charm Feb 28, 2026, 2:12 PM

#

iron rampart The bendy one

pipes that dont collide with normal pipes. its basically all prototype stuff, then a bit of scripting just for swapping layers and converting items

balmy charm Feb 28, 2026, 2:12 PM

#

iron rampart How would that even work. Do you need to make a new surface and use linked belts...

yea

#

it'd be beltlayer with AUP controls

iron rampart Feb 28, 2026, 2:12 PM

#

That actually... sounds way simpler than what I did

#

Crazy mod idea. Space platform underground belt that just drops the items into space

balmy charm Feb 28, 2026, 2:14 PM

#

lol

iron rampart Feb 28, 2026, 2:14 PM

#

Or how about if you could conveyor belt directly off the edge and you didn't need to use an inserted. Same for lava

balmy charm Feb 28, 2026, 2:14 PM

#

been doin this recently

iron rampart Feb 28, 2026, 2:14 PM

#

Huh?

balmy charm Feb 28, 2026, 2:14 PM

#

flow control/flow config without the GUI or items or recipes

iron rampart Feb 28, 2026, 2:15 PM

#

Flow control having 6 different pipes is the sole reason I do not use it

balmy charm Feb 28, 2026, 2:15 PM

#

happy to replace it :D

#

i will immediately be marking flow control and flow config incompatible

iron rampart Feb 28, 2026, 2:16 PM

#

I recently beat industrial revolution 3 and I gotta say the one way valve from that mod is peak design

balmy charm Feb 28, 2026, 2:16 PM

#

you can make cool stuff like this (prototype thumbnail)

#

all with basic placing pipes

iron rampart Feb 28, 2026, 2:16 PM

#

The valve is a one way, overflow, and top up all in one.

balmy charm Feb 28, 2026, 2:17 PM

#

oh fr? neat

iron rampart Feb 28, 2026, 2:17 PM

#

U just interact with it to switch it it's so ez

balmy charm Feb 28, 2026, 2:17 PM

#

finally, not three recipes for bascially one item lol

iron rampart Feb 28, 2026, 2:17 PM

#

Would love a overflow or top up pump in factorio

balmy charm Feb 28, 2026, 2:17 PM

#

i mean... we have those in-engine...

iron rampart Feb 28, 2026, 2:18 PM

#

Don't you need circuits?

balmy charm Feb 28, 2026, 2:18 PM

#

nah

#

not really

iron rampart Feb 28, 2026, 2:18 PM

#

Then how

balmy charm Feb 28, 2026, 2:18 PM

#

they got added as a prototype

iron rampart Feb 28, 2026, 2:18 PM

#

Oh ok

balmy charm Feb 28, 2026, 2:18 PM

#

thats what most 2.0 mods use as valves instead of weird jank

iron rampart Feb 28, 2026, 2:19 PM

#

Industrial revolution 3 actually has so many good ideas

balmy charm Feb 28, 2026, 2:19 PM

#

ill give it that, it was unique

iron rampart Feb 28, 2026, 2:20 PM

#

U can see the inspiration in the space age dlc

#

Honestly like it better than vanilla factorio

iron rampart Feb 28, 2026, 2:22 PM

#

balmy charm you can make cool stuff like this (prototype thumbnail)

I need this

balmy charm Feb 28, 2026, 2:23 PM

#

its on git if you wanna play with it :D

iron rampart Feb 28, 2026, 2:23 PM

#

Actually even more than this I need a version of fluid must flow that doesn't have 8 different parts

#

That mod really needs an update

balmy charm Feb 28, 2026, 2:24 PM

#

fr

iron rampart Feb 28, 2026, 2:24 PM

#

An like why isn't it 2x grid locked?

balmy charm Feb 28, 2026, 2:24 PM

#

i would redo it but im over destroying the engine with fluids 😭

#

i swear every time i make a fluid mod i find at least one crash/bug/ctd

iron rampart Feb 28, 2026, 2:25 PM

#

Industrial revolution had a long and short underground pipe

#

Worst idea In that mod

balmy charm Feb 28, 2026, 2:25 PM

#

just make tiers smh

iron rampart Feb 28, 2026, 2:25 PM

#

I felt compelled to microoptimize with paltry quantities of iron playes

#

I would rather nuke myself than have to choose between long and short of any underground ever again

#

In my mod I set all the underground lengths to be same as turbo, but I could go higher

#

My goal is kinda to replace every single long underground belt mod

#

There are a lot of them

#

Do you think 32 tiles is long enough?

#

It's a whole chunk. I'm sure most players will be satisfied with that but I wonder if the engine can go farther

balmy charm Feb 28, 2026, 2:55 PM

#

probably wouldnt appreciate it

#

my eventual goal with these type of mods was researching length upgrades so you could build longer undergrounds (but the same items ofc) but that never happened obviously

iron rampart Mar 1, 2026, 1:28 AM

#

Researching length upgrades is interesting

#

Personally I find it annoying how each tier of belt is a different length

balmy charm Mar 1, 2026, 2:00 AM

#

right?

#

like, its just underground supports

iron rampart Mar 1, 2026, 3:33 AM

#

@balmy charm what should i call my mod?

#

how about "underground belts require transport belts"

balmy charm Mar 1, 2026, 4:34 AM

#

that sounds good

iron rampart Mar 1, 2026, 5:04 AM

woo its done
