Factorio Weekly Question Thread

After playing the demo for a little while (and deleting the biters using commands), I decided to purchase the full game. At first, I was worried that I would regret the purchase because the demo didn't show the game's full potential. After buying the full game and playing for about 10 hours in one day, I realized just how much I loved and would love the game.

My initial base was a mess of spaghetti that was impossible to expand and was horribly inefficient, so I looked online and found out about main busses. I quickly adopted the system and led my factory downwards as it had the most room and the least obstacles. My factory was producing more than enough red and green science for my needs as well as steel.

I generated my map with biters off because I wanted a calmer experience where I could learn the game, and not have to worry about pollution or defence. Other than that, map generation was set to default.

The atmosphere of the game created by the visuals and sounds fit perfectly.

The demo of Factorio was a sliver of the content contained in the full game and I believe that the full game was worth its price.

For anyone considering buying the game, if the demo was even a little bit interesting to you, the full game is much better and worth its price.

Math behind balancing

Posted: 10 Nov 2020 06:57 AM PST

I've always been pissed off by balancers because I just couldn't get it. I saw the same designs online again and again but I never understood how it's possible to get three equal belts out of one. Actually it's impossible to achieve this with only one iteration (=first run through the assembly) because it's a prime number. The latest post about balancers got me thinking so I decided to do the math and share it, even though I doubt many people will take interest.

First iteration, 100% goes in the first splitter, 4* 25% come out after the second. 25% are fed in the intake, so now we got 125% (5/4) , 4* 5/16 come out. This leads to 21/16 intake & 4* 21/64 output, 85/64 intake & 4* 85/265 output and so on.

I could see that the values come closer and closer to 1/3 but I wanted a proper formula - after all, this is a game about automating stuff and not doing it by hand. ;)

Looking at the numbers, I noticed that (with fraction=a/b and number of iterations=m respectively n)

aₘ+bₘ=aₙ and

aₘ*4+1=aₙ

Combining those two leads to

aₘ+bₘ=aₘ*4+1

aₘ=(bₘ-1)/3

b obviously is 4^n, so that leaves us with

f(n)=(4ⁿ⁺¹ -1)/3*4ⁿ⁺¹

The higher n becomes, the less significant (-1) becomes, so with n=infinite we're at 1/3 even.

So they need some time to get the right output ratio, but how long exactly?

The 1-3 balancer takes 4 iterations for 0,3330 and 9 iterations for 0,3333330.

With the most compact design and red belts this leaves us with 6,4 seconds for 3 decimal point precision.

An easily defended seed with enemies turned down makes you lazy. Still launches rockets. (~20MB image)

I hate rails. 1k production science is a lot harder than I thought because getting the 125 rails a second was a pain. After some help with my 1k military science build I was able to redesign it to this. Any suggestions or help is appreciated.

Posted: 10 Nov 2020 05:02 AM PST

I forgot to mention but its a 8 beaconed build at least for the production science assemblers.

I updated the build because I felt I could make the red and green circuit belt mixed in the build instead of out side the build.

Rockets & Space Science

Posted: 10 Nov 2020 12:34 AM PST

I'm not getting any space science from rocket launches.

I build the rocket successfully, stick a stack of satellites in and launch it and no space science.

Is there something else I need to do to?

Should the silo have an inventory slot I should see the science in? I've got a slot for the satellites to go in but that vanishes when the rocket launches.

I may be missing something simple but I've no idea what.

Spidertron Issue

Posted: 10 Nov 2020 07:18 AM PST

I was driving the spidertron into combat, but the biters were too many. I ran for a small 1-tile island and the biters froze. I was safe.

Then the UPS, normally a pleasant 60.0, tanked and fell to 4 and started crawling down. The other users connected to the server began having issues until I stepped off my island of safety. Everything returned to normal and I was crushed by the wave of natives.

Excited, I jumped on to the Factorio website to submit a bug report. Alas... it has already been reported and fixed. Maybe I'll find a bug next time...

Un optimized setup for 111item start (it my first time doing it only 14hr on the game in total and 1on the map ) i'm slow

I have about 200 hours in game and haven't been able to launch a rocket yet because my base always ends up being a mess before preparing for a rocket. I think I'm going a bit too far this time around trying to remain organized throughout the entirety of this run.

Starting out

Posted: 10 Nov 2020 05:19 AM PST

When people start out do you start working on a bus system or do you wait till you get robots to start that?

Best spawn I've seen so far. Figured I'd share it with you fine folks.

Enjoy!

Factory scaling

Posted: 10 Nov 2020 04:35 AM PST

hey all, I was wondering how all of you get around the problem of factory scaling. like for example:

when i first started setting up my assembling machines, i thought 4 copper wire assembly machines near my copper smelters would be enough for the game, if you count on speed modules and better tier assemblers. Ive gotten to the stage where im approaching blue circuit board production and man ive had to quadruple my copper wire production. now this has lft my lovely factory looking like spaghetti junction with the amount of retro fitting ive had to do to get these new wire assemblers from my copper refineries way out yonder to the assemblers making red circuit boards on the opposite end of my factory.Now this is just a random example and is probs the core of factorio but id like to hear your input on this. the only time i ever get space in my factory is when my ore fields dry up and i move my drills and belts (lol having to stop research for 2 hours as you realise your dwindling coal and laser turrets have but you in an energy crisis)

Bobs/Angels Ingot Management

Posted: 09 Nov 2020 02:23 PM PST

I'm currently on a Bobs/Angels run with a friend and our smelting is a mess. So we decided to set up some new ingot smelting, so we can mix them later into the propper plates and other products. To prevent the confusion with all the green (Tin, Zink and Nickel), grey (Iron and Silver) and white (Steel and Silicon) ones, I decided to label them.
