I've been working on a tool to automatically convert the Factorio Lua data into a JSON format more reasonable for other tooling. To this end, I'm looking at parsing the Wiki data to automatically write the parser [1]. One thing I've noticed is that the semantic mediawiki information for the prototyp...

The train pathing penalties are listed here: https://wiki.factorio.com/Railway/Train_path_finding

Looking at your image, the train on the left is the lowest cost path, with a penalty of 500 (train stopped in station), while the others have 4000 or 6000 penalty for having stations.

"class std::basic_string,class std::allocator >"

I think there is missing some escaping...

Probably std::basic_string<char, std::char_traits<char>, std::allocator<char>>

Perhaps somewhat sad that I know this off the top of my head...

These are the notes I wrote before doing my speedrun, back on 0.13 [1]: Goal: 8 hours Stockpile: * 9200 steel (92 stacks -> 1 chest + 44 slots) * 7700 solid fuel (154 stacks -> 3 chests + 10 slots) * 4100 copper (41 stacks -> 1 chest) * 4100 plastic (41 stacks -> 1 chest, ~2733 gas) * 1000 concrete ...

I think this posts sums up pretty quickly the thread (:joke:) : the fact that Factorio updates thousand or millions, even nearly a billion action every tick, is absolutely not compatible with multi-thread. Not with x86 arch at least. With a thousand core ARM PC (which doesn't exists, only a few try...

1 x Global List/Array/whatever of pointers to all entities, each with a type inside it. 1 x List/Array/whatever for each "type" of entity that needs to be handled separately, stored as a set of pointers to each of those entities. Even for a thousand particles, the memory overhead is pathe...

You have water and steam throughput issues. You might have heat throughput as well, but I don't know the heat transfer equations in Factorio well enough to be sure. Each set of 12 heat exchangers consumes ~1237 units of fluid/sec, an offshore pump provides merely 1200 fluid/sec. Water is therefore t...

-then they got their words mixed up because that's not what ''pressure'' means in real life. They're talking about quantity. And the way fluids work here is just so odd, for example if you connect 3 tanks in series, first tank has 80% quantity of water, the next one has like 40% and the next one ha...

When I said pressure, I meant flow rate. In that case, I don't understand how pressure works in factorio then. Are they 2 different things that exist in factorio? I assumed that flow=pressure in factorio. In Factorio terms, pressure is how full a pipe or tank is: a 1000 unit pipe with 900 units of ...

Let's say I have 1000 sections of pipes, and at the end I put a pump... that pump will be worthless! As the pipe gets longer, the fluid speed decreases... but the pump cannot raise the speed, because it receives a low amount of fluid. You can put a tank but then that tank gets filled at a slow spee...

Just having the three splitters at the end is sufficient for most use cases. It won't give you full output if all of the input is coming in along solely from one half of the input belts, but you can generally feed the inputs such that the emptier belts feed the outside and the fuller belts feed the ...

Based on the heat capacity of water in the game, at STP, we calculated that 1 fluid unit of water should be about 50-75ml i.e. 50-75 cm^3. Based on that, the pipe seems a bit large, but this doesn't hold when you try to compute volumes from other fluids' heat capacities. And of course Nauvis isn't ...

Oooh, yay, we finally get machine-readable information on the prototype definition schema! If you want some code to actually machine-read the data, here's some python code I wrote to collate all the data: #!/usr/bin/env python3 ''' Create schema data from the Factorio wiki. ''' import json import re...

Unfortunately, the FFF still doesn't address one of the biggest problems people had with the change. Many people, including myself, are of the opinion that the major reason oil is so complex is because it throws people into a multiple-output scenario in an environment where both the cause of issue i...

I sincerely hope that FFF#305 will be a response to the massive feedback (to put it lightly) of the oil change. I also hope they're still reading all of the entries in this thread, even if they aren't responding to all of them. As I see it, there are several options for moving forward, which aren't ...

Let's add some more fuel to the fire of oil changes: The oil cliff is definitely real, even for advanced players. But why does it exist? After you've set up red/green science production, your choices of expansion are to move into better logistics (trains, red belts), which you likely don't have a re...

As for mergele... shouldn't it be like this though? With a chain signal at the entrance, so that trains only go in if it's clear in the 2nd half of the circle as well? so tl;dr middle signals is so that a north and south train can both go forward without distracting each other. 3341.jpg All signals...

So in this picture, judging by the signals I have, the train will simply refuse to enter the track without signal? I don't understand why it would work like that. What's stopping it from entering the track without the signal? Trains refuse to path into a block without a signal protecting the entran...

Most areas simply do not have room for the train to turn into a circle and the tracking required would be MASSIVE Railway setups usually take lots of space. Balloon loops (the technical name for turnaround tracks at stations) are much, much smaller than high-throughput 4-way railway junctions. That...

As soon as you add another journey or other roboports to the same network, bots will dynamically switch between journeys/tasks as they are needed and also pause at different roboports to recharge along the way. It will be impossible to use a formula as there are a multitude of journeys and no way t...
