The planet is generated from single tile that can be flipped and rotated to create multiple variations. The only random input is how these rotations and flips will be arranged next to each other. If I understood the last FFF correctly there will be no small island with ore unless the devs decided t...

I like the new machines! But I notice the ear ratio is wrong on the new mining drill. When moving left/right, the little gears spin way more than they should for the amount of motion and the spacing/size of the teeth. You’d be grinding off gear teeth if they spin that fast. I missed that, but somet...

If I wanted my locomotives to run on a lesser fuel if the preferred fuel was unavailable, I would simply use a priority splitter or circuit priority mechanism.

RIP to you guys, but I'm different.

The argument about furnaces getting their fuels and inputs confused is reasonable, though.

It could sort by the concatenation of name, " ", and (whatever the sorting key is now). That'd give predictable behavior for people who name their blueprint books, and degrade gracefully for people who forget. (All unnamed books would sort together.)

Here's a throughput-measuring contraption that works up to 6000 fluid/s and is precise to the number of significant figures provided by the production screen: meter.jpg 0eNrNmd1umzAUx1+lsrSbjay2Q0hAW+/au91UvZuqiBAnsQYGGZMuqniAvcWebU8yA2tC+LRpluSmKjE+HJ/f+R8fwytY+AmJOGUCOK+AeiGLgfP9FcR0zVw/+03sIgIcsP...

Won't work in 0.17.68. the splitter priority trick is obsolete. Throughput ≈ 3.76 belts with priority set Throughput ≈ 5.04 belts without priority set sideload splitter trougput comparison.png That's not the splitter priority trick. This is the splitter priority trick: inserter_timing.jpg Still wor...

UPS testing results are in, on Reddit. Very promising. The result for the one with splitters may not be correct, because of the problem @eradicator found. Somebody on Reddit just posted the same solution as Vegemeister .... :mrgreen: https://www.reddit.com/r/factorio/comments/d3d3jf/filling_a_train...

I'm slightly worried about that regular grid pattern in the landfill terrain creating moire artifacts when zoomed out. Didn't the old concrete terrain have that problem? Whichever scaling method Factorio uses at <100% zoom has considerable aliasing. It's especially noticeable on electrical wires. Th...

I remember reading something from the Bob's Inserters discourse about inserters with configurable pickup and drop positions being fastest when both are as far as possible from the inserter base. Apparently the inserter speed limit applies to angular speed, or something like that. The best vanilla in...

I only play with belts Your play style is more restricted than you think it is. You're not just avoiding bots and trains, you're also avoiding direct insertion, buffered direct insertion, and short internal belts. High volume intermediates are a problem you're supposed to solve by intermingling ass...

The thing is, for fluids and electrical entities, I'm pretty sure running at less than full capacity does not reduce the UPS cost. So if you can't use solar exclusively, there's no reason to use it at all, at megabase scale. At sub-megabase scale, it's better to put eff1 modules in things than to bu...

This works (the left curve in front of inserter #3 is non-optional):
However, just because you can doesn't mean you should. @mrvn is right. Just make the train twice as long.

So, I have a few contributions to this thread. First, a brute force 3-belt-per-side unloader, which is actually 3 single-belt unloaders neslted together: 3-belt-w6.png It's 7 tiles wide and has no unusual alignment constraints, so it works for any number of wagons. Murder on UPS though. Next, a 3 ti...

In 0.17.56, there will be config.ini setting "compress-sprite-atlas-cache". At the moment it uses compression level 1, we may change it to -1 in the future. Also it doesn't utilize parallel compression/decompression, so I am not sure if it'll make 350 MB/s resp. 1 GB/s on your PC, but it ...

Entities aren't updated in the order they're allocated and additionally virtually all entities that are updatable have dynamically allocated member data or touch other entities/data sets they don't own. So, none of that actually works in a real-world scenario where all things that do logic end up b...

The main application is elementwise multiplication of all signals on two wires. That is, each = each * each.

I think it can also be used for IIR filters.

The mod portal website is currently displaying screenshots with image-rendering: pixelated or image-rendering: -moz-crisp-edges, whichever is supported. This causes the browser to use the nearest-neighbor resampler, which makes text nearly illegible and is otherwise unattractive. First screenshot fr...

Bump, so as not to just be urgin' for a mergin'. The way it is now, there's practically no reason to ever use bidirectional trains. Their only advantage over single-headed trains is that you save a little space around stations and don't have to use underground belts to cross the exit tracks. Without...

And similarly for production: the maximum should if all generators (except accumulators) were producing at full rate. This IS very useful info. All electric producers can be reasonably expected to operate at 100%. If they can't it almost always means something is wrong (or the sun is going down). S...

This could also be the same bug: viewtopic.php?f=182&t=67242.
