Why estimating the angle instead of using its exact value?
As you have noticed, it is "1:2 triangular ratio", so in Lua it may be calculated as

local rail_est = math.atan(1/2) / (2*math.pi) -- approx 0.0737918



Because when i tried with 0.07386350632 earlier vs your 0.0737918, my earlier ...

Given the above, it would be amazing if you re-posted that picture, but with show-tile-grid on !


I edited the previous post, it includes grid now. I need it myself too to find out actual angles, unless there is a list for those numbers somewhere?

I also did a test of the angle table with Unity ...

I'm not sure how i feel about the patch as in including it in or not. It's true the angles between cardinals and diagonals are off, i took a little screenshot of current rails:

Your math is also something i don't follow :P
My thought after was to record those key angles into a ...

TL;DR
Placing a different tier underground belt over another underground belt should not change the direction of the one in hand when replacing a whole pair .

What?
It is understandable that if you are building the underground belts you do them in pairs, entrance and exit. But when you click ...

I have a fix for you in a form of a mod if interested; PersistentZoom:

Did you read Raiguard's post just before yours? Basically connecting thrusters together like that is not allowed anymore, it just won't work by design. Fluid mixing is no longer a thing, if there is 2 different fluids then the one that is lower amount is erased from existence.


Hi Zaflis ...

There is no negative quality, 0% is lowest effect it can have. Even then the spoilage isn't some % based but by quality rank the item is given, common, uncommon, rare...

So there are at least these 2 options or both:
1) Changing the tooltip text for efficiency modules, clearly saying that reducing energy cost also reduces pollution.

2) New page or 2 to ingame tips about pollution. I just now did a word search in tips with "poll" and it came out nothing.

TL;DR
It would be nice to see for example total (or average?) pollution produced in the timeline, because it is hard to tell your progress from several separated curves.

What?
While the idea doesn't only apply to pollution, it can be useful for at least kills graphs, pollution is where it makes ...

I have a topic here with more details:

I would not have been able to find this information; auto_recycle, can_recycle without google. So here it is again:

Main part is this though:
local can_recycle = can_recycle or default_can_recycle

So yes i did come to notice that if they need to turn once they will drop down to the new closest angle. That's not bad actually, it's just the first shot may require some more turning if it's way wrong.

Your character is (really travelling, not just remote view) onboard the platform too at the time?

They are likely going to need to see your source code. It takes time even for them to go through API's and figure out steps you are trying to do, of which you could have made typos too.

What does the achievement UI show you about the achievement? It should show if it's currently achievable or not.

Concrete should recycle 10 times faster.
It's annoyng how much recyclers I must put to destroy concrete. One per every five scrap recyclers.

There is a little workaround for that currently, adding a middlestep to craft the concrete into hazard concrete. That in turn will recycle much much faster ...

I'm having the same issue of not achieving logistic network embargo with space age. I have the following unique conditions:

- I don't use steam. My game is directly downloaded and independently installed. No steam is installed on this PC
- I have never achieved any logistic network embargo before ...

I haven't tried science productivity yet, but scrap productivity is capped at 300% (i hope they change it!): (320% will cost 215M of each science and something like 3h 30 mins at 1M eSPM)

Agreed, when i was making treefarm i used some lamps in the copy/paste blueprint as area markers for workaround. It took some trial and error to get them to right spots.
