Nope. You need to make new rail blueprints. The curve radius has changed and the curve pieces have changed, so there are vastly more options to construct rails, switches and often better signal placement at intersections.

[picklock]

You will have to rebuilt all your blueprints for rails. the rails from V1.1 are not compatible with V2.0.
See Frieday Facts #377 - New new rails .

... As you can probably guess, the new rail curves will be incompatible with the old ones. Savegames from 1.1 can be opened and trains will still run on previously built rails just like normal, but you won't be able to construct the old rails at all anymore. ...

Hey guys, having trouble figuring out the set recipe function in an assembly machine. I'm trying to use one assembly machine to do "empty water barrel" and "fill water barrel", the problem is the orientation of the pipe keeps flipping whenever the set recipe changes.

https://streamable.com/7b2gqs

At first I thought it was just the default orientation of pipes to always face downwards so I tried the other way, but unfortunately it just flips to the other side regardless.

Can anyone help with this? It would be great if it can maintain the pipe orientation.

Thanks.

Hello,

I'd like to make a logic system based on time. To do this, I've tried to make a timer that sends a signal every x seconds. I found the number of ticks per second on the wiki (60/s) and built my system.
Unfortunately, there's a problem that I can't work out what's causing it.

I've put the blueprint here. The system simply works in two parts.

The bottom part increments 1 for each tick up to 60, then resets to 0 (by subtracting 60) and sends a signal to the top part on each loop. This basically converts ticks into seconds.

The top part works in exactly the same way, this time counting seconds rather than ticks. It's supposed to reset every 10s. Except that when it reaches 10, instead of doing -10 to go back to 0, it does 2x -10 to go back to -10... (I tested this to be sure that the problem was really there by setting -5, the result is 0, i.e. 2x -5).
I don't understand why the comparator (surrounded by the walls) that tests if the value is 10 outputs its signal 2x instead of once. It's configured like the lower one and the lower one works...

I suppose it's obviously more likely that I've done something wrong than that it's a bug, but I really don't understand what's wrong.

Thanks in advance if anyone can find out why it's not working the way I want it to.

I don't understand why the comparator (surrounded by the walls) that tests if the value is 10 outputs its signal 2x instead of once. It's configured like the lower one and the lower one works...

The red arrow (output) goes directly through because it's all on the green wire. Then the yellow comes again, because of the loop.
But even when decoupling this output (red) the blue way takes multiple ticks to process and until then the memory cell (yellow) will still send it's looped value.
So there are multiple issues. I recommend using the editor and single tick stepping (Numpad ,) - very useful for debugging such cases.

Why not using a simple decider counting up to 600? Then divide it by 60 to get the seconds?

Thanks for your reply.
It's true that you can make it work with a single loop that counts 600 ticks, or as I did by replacing the -10 with a -5

But I'm curious to understand why it didn't work as I thought and I'm not sure I understood your answer.

Why does the ‘blue way’ take several ticks to make, whereas in the bottom part it works in 1 tick?

[r3nt5ch3r]

Why does the ‘blue way’ take several ticks to make, whereas in the bottom part it works in 1 tick?

The bottom part uses +1 in the memory cell, thus on each tick the value will be different. This ensures that your subtraction only happens once. The roundtrip itself also takes multiple ticks there.
The top part has +0 in the memory cell, leading to the issue that the value stays the same over multiple ticks.

Every combinator has 1 tick latency between input and output. You can interpret it in a way that it needs 1 tick for a combinator to read the input, evaluate the condition or operation, and output the result. So a combinator with a direct loopback from output to input has 1 tick latency between the previous and the next state. If you add more combinators in a loop to handle some value from a direct loopback, it takes one additional tick for every added combinator for that modified value reach the original combinator. You even have 3 combinators in a loop, so this is what happens:
tick 0: the input value in the "+" combinator is evaluated and the input for the "=" combinator created
tick 1: this value is evaluated by the "=" combinator and the input for the "*" combinator created
tick 2: this value is evaluated by the "*" combinator and the input for the "+" combinator created
tick 3: this value is evaluated by the "+" combinator, which increased the counter value by 3 in the meantime because of its direct loopback.

The common counter is implemented with a decider combinator with input and output connected. Feed a C=1 for increment, as condition set C < [limit], as output set C=input value. As long as the condition is true, C is looped back and so increases. If the condition is not true any more, because C increased over the limit, C isn't output any more, so it cannot be looped back to the input, so the counter forgets its value and starts again with 0, which makes the condition true again, and the incrementing starts again.

I'm playing current stable version 2.0.15.

I just tried the experimental version 2.0.17 but the pipe orientation still flips as it switches. Would this be considered a bug or a feature? I'm wondering if I should report it.

Thanks

Hi, does building the rocket from higher quality parts have any benefits? Or is it the same time no matter what quality is used? Thanks

[Barthoze]

Hi, does building the rocket from higher quality parts have any benefits? Or is it the same time no matter what quality is used? Thanks

If by rocket parts, you mean the low density structure + processor + rocket fuel assembled in rocket silo, then quality has indeed no influence as of 2.0.15 at all on the rocket you send to your orbital platform, be it speed or capacity.

The rest is influenced by quality.

Thanks yes that was what I meant

[BlueTemplar]

Quality does have influence, since AFAIK rocket parts is a very special recipe that you can NOT set to use quality ingredients ?

hello, I don't know what the purpose of defining the ghost cursor on the map is. I thought it created ghost entities once the large map was removed but I don't really know. I define the cursor I left click on the map and nothing happens

[BlueTemplar]

Yeah, kind of weird when 'full' blueprints work (even if it's just a single entity), but this doesn't. It will work if you zoom into normal remote view though.

hi.Tell me.Is it allowed to use high-quality resources in any construction?
Higher-quality eggs cannot be used to create flasks.
Higher-quality nutritious food is not used to create eggs.
