oh, my bad. Apparently I was misremembering things. Looking up the actual formula from the wiki, it gives 10% * (level - 3) while costing 2500 * (level - 3). The ratio between them is (2500 * (level - 3) ) / (10% * (level - 3)) = 2500/10%, which is constant. Therefore, given everything else in the ...

It's not the numbers of reactors that is relevant but the number of GW of power you consume. Running twice the number of reactors but only fueling it every 400s is more efficient. Although the difference becomes rather small at 640 reactors vs 1280 reactors. But you should calculate this for an inf...

Why are you repeating what I wrote?

One prod module is a fixed investment, just like the mining productivity research. The research creates more ore output out of thin air. Essentially, it enlarges every ore resource by the researched factor. The prod modules convert energy into more output of every intermediate material, so they red...

Not really.

You can have inserters remove from fuel inventories with or without this. While there might be some overlap for changing the trains fuel type the two suggestions are largely independent.

I'm surprised that no one in this thread compared putting speed modules in miners vs productivity modules. The following calculations are assuming that miners are moved to a new patch when the old one depletes. This does ignore the benefit that the patches last longer with prod modules but that is ...

Maybe the maze was just a pre-defined map and not generated. So all you need for that is download the map at the start.

As for things appearing maybe the server runs custom lua scripts, which would send the script to all clients and then all of them run them so nothing desyncs?

There is far more to this than wire distance though. The electric poles remember the last place they could be placed and the entities they would power. Then when next location either doesn't have the wire reach or doesn't power all remembered entities the previous location gets a pole. So for your f...

You can already do this yourself. You know the limit of each stop and the stop outputs the number of trains targeting the station. So all it takes is subtracting one from the other and having circuit wires between all train stops or using one of the wireless circuit network mods to share the overall...

Not having a blueprint means a lot of this is just guessing. The arithmetic combinator "+1" is supposed to add one to each every tick. And the decider combinator "each < 120" makes it a cyclic counter. There is the first problem. The construct has 2 ticks latency. You actually ge...

Which now makes me wonder why straight pipes don't have directionality. They do have directionality. There are no exceptions. This is how fluid system works: first, all entities are evaluated in their build order, then all active joints are evaluated in order of cardinal directions. Note that every...

I think I picked a bad example. With the electrodes only looped internally the block only has the distilled water as input. So you can use the input driven way. I know I had cases with blocks having 2 or more inputs but it's hard to make one up on the spot. It's interesting to see the matrix solver ...

Two important things for this design: 1) Place a chain signal before the entry into the depot. That way trains that get stuck and can't enter the depot for whatever reason will pick another train stop to go to. Without this they would start to enter the depot and then get stuck already on one of the...

But what seem to happen is that the items are dumped into the arriving train before LTN output combinator gets programmed. I think this happens at the temporary stop I know the issue, it's been there from day 1, long before temp stops even existed. That's just how inserters operate. They shove thei...

I have a station that provides multiple items and does count perfect loading by removing any excess items. This usually clears all loading inserters so when the next train arrives they pick up the right items and load them. But sometimes a full cargo wagon is requested. That means the inserters fill...

TL;DR Change the fuel inventory in vehicles, furnaces, boilers, assemblers and inserters to use the same interface and features as cargo wagons. What/Why ? Cargo wagons have features that would be useful for managing fuel in other entities: 1) The inventory size can be limited so inserter only fill...

Asynchronous, multithreaded: you hire two more cooks, one to cook eggs and one to cook toast. Now you have the problem of coordinating the cooks so that they do not conflict with each other in the kitchen when sharing resources. And you have to pay them. https://stackoverflow.com/a/34681101/3812928...

Programming for multithreading is a bit like designing a train network in Factorio. In both cases you have to avoid deadlocks. Except in a program, you may have millions or billions of trains each carrying a unique cargo, and you're up against the constraints that you can't have two trains carrying...
