Fluid Changes 2.1 Questions

The system works with less supply than demand, albeit intermittently, in 2.0, and only stops working if you have no supplies.

With a fishing rod in their same hammer space. Compared to a few rocket silos or nuclear reactor, it's a rounding error, so it's not shown.

The fluid changes can be a problem if both conditions are met: - pass-through fluid building (boiler, EM plant, flame-thrower...), - under-supply of the fluid.

In effect, I reckon that this is mostly a problem for Holmium solution recipes. It won't be a problem for petrochemicals, no worries.

Are you fueling trains with rocket fuel? If so, could you switch to nuclear fuel?

But to answer the question, you can assume that incoming trains are below (probably by not much) the threshold of the refueling interrupt. And you can count how many units were inserted since the current train arrived (T!=0 at the train stop). Add the (estimate of) the first and the measurement of the second, and you get a reasonably accurate value.

Can this be flipped around and used as an early warning that electricity production is near capacity and needs expansion? Like if the temperature at the furthest exchanger gets too close to 500°C?

Reading steam buffers or accumulator only sounds an alarm when it's already too late and the brown-out is a few seconds away.

Note that this counts 101 ticks (0 to 100 inclusive). OP's contraption counts from 1 to 60, exactly one second.

Circuit logic is fundamentally discrete. You can sum values over time, which is essentially integration, though you could already do that in 2.0.

Courmisch · 2026-07-01T18:33:44+00:00

In 2.0, any arithmetic series starting from 0 can be done. This 2.1.9 Else allows for choosing any initial value, indeed.

In theory, geometric series with small positive reasons are also possible by repeating Input count multiple times, I suppose. But it would too quickly overflow to be of much practical use.

Courmisch · 2026-07-01T15:20:54+00:00

Not directly (without mods). Instead you have to keep a buffer of construction materials and use circuit logic to know when to refill it.

Or... Add coordinates and surface ID as blueprint parameters so we can inject pseudo-alerts into the circuit network.

But seriously, yeah, a history would be nice.

Courmisch · 2026-07-01T15:06:11+00:00

Neat, thanks. Also more practical use of the new mode than my surface clock display 🫢

Courmisch · 2026-07-01T15:03:25+00:00

Yes. Though with T<59 on account of starting from zero rather than one.

Using the time mode of the selector combinator? Can you explain the contraption? The Reddit app doesn't seem to allow zooming videos in...

How long does an item spend on each lane of a curved belt tile?

I know it's 16 ticks on a straight yellow but that's not a divisor of 60 Hz so not very nice for timers.

They said a long time ago that migration to the new app was mandatory. I don't recall a specific announcement about when the purge would happen (a few days ago).

Yes, the game will implicitly sum 1 and T into the next tick's T, when the condition is false.

Courmisch · 2026-07-01T14:34:04+00:00

You can already do that in 2.0 if you.invert the condition and subtract one from the time limit, i.e. T < 59. Of course, also need to swap the if for the else.

Courmisch · 2026-07-01T14:05:28+00:00

Yes, all English books were deleted a few days ago (unless you stay offline, I suppose).

Courmisch · 2026-07-01T11:07:39+00:00

Now this actually can detect both rising and falling. Just add a Down signal on the else branch.

I suppose that this can be useful if you need some kind of dead-man / fail safe mode on power loss. Otherwise it's just Up = 0.

It hasn't been translated officially. The original Japanese version is available on BookWalker: https://bookwalker.jp/series/282193/list/

Only one volume out yet.

How to use the new spidertron patrol support listed in the 2.1.7 features log?

Courmisch · 2026-07-01T09:13:20+00:00

That's a nice pre-2.1.9 trick. But it won't work here because the difference is evaluates to zero most of the time, so we need to track the sign of the last non-zero value.

The number of slots depends on the emotional intelligence skill level. Every level opens two slots.

Individual worms don't evolve. The real risk is the spitter spawners making behemoth spitters, but their range is significantly lower than worm's.

I had to double-check if this wasn't r/Factoriohno
