Intro


General informations

Here is some general information that should help you better understand this guide.

Naming

It can easily be confusing reading “high”, “low”, “1” and “0” if you never got in contact with logic gates before, but it is really not that difficult.
You just need to remember that, in the context of this guide, “high” and “1” mean the same thing as “on”, and “low” and “0” mean the same thing as “off”.

Signal strength

The strength of a signal generated by a generator can only travel a limitet count of tiles with full strength. After that it will get weaker from tile to tile.



To counter the signal limit, without changing the logic of your circuit, you can use the signal amplifier descript in this guide.

Truth Tables

Truth tables are used to help understand what different logic gates do.
If you already know what a truth table is and how to read it, you can skip this part.
For everyone else, I’ll try to explain truth tables as easily as possible.

Explanation

A truth table shows all different “states” a circuit can have. Each row represents a different state of the circuit and each field in a row represents the state of an input or output.

Take this truth table for instance:

Input 1
Output 1
0
0
1
1

It shows that the circuit has two possible states.
In the first possible state the value of “Input 1” is 0 and the value of “Output 1” is also 0.
In the second possible state the value of “Input 1” is 1 and the value of “Output 1” is also one.
If we ignore that a wire in the game has four sites, and if we define an input and output site of that wire, we have the circuit to our truth table above. A wire can only be on or off and if the input is one the output is on too and vice versa.

Truth Tables visualize every possible input and the corresponding output.

Signal Amplifier


Because the signal only travels a limited number of fields, you might want to amplify the signal, without changing the logic of your circuit.

Thank you, the clock works perfectly.

@Phantrom Put a generator where Input 1 is, and Output 1 will pulse every second.

Can you explain how the clock works? I don't understand the electricity stick

That sucks, I'm sorry to hear that.
I'm also not sure how much of the ownership you give up by publishing it to Steam and if you would even be able to do something like a DMCA claim if you wanted to. I did not find any information about that directly from Steam.
But even if you managed to take down one of these Ad-Farms there would just be a new one a week later.

I found that all my Steam guides had been scraped, too, a couple weeks ago when I Google my own guide. an ad-farm version beat mine to the top position, annoyingly.

I've not done a deep look, but I've seen "gameplay.tips" and "indiefaq.com" , so far. I left a comment on the former, to inform them the version they'd taken without permission was outdated and wrong. They binned my comment but updated it within the day.

I've doubted there's anything I can do, but thought of adding a creative commons copyright note at the end, like the wikizet has: "Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)".

I'm not sure what Steam's (legal) position on this would be... But then they've failed to fix, for 3 weeks, the issue with clicking to expand embedded images throwing up a dumb error page. :steamfacepalm:

Thanks a bunch, but I don't think that it is worth the time because Steam guides aren't monetized. I found 6 sites now and all of them seem to be automated “content” farms so it won't do much anyways.
I could try a DMCA claim but that could come with a fee and even if the site gets taken down there would just be a new one a week later.

I just sent some feedback to Google, hoping it will no longer get pushed in the search results. If this works it will hopefully not get that much traffic with stolen Steam guides anymore.

Good luck from me to.

Whatever you choose to do good luck :steamthumbsup:
basicx  [author] 15 Sep, 2022 @ 9:47am 
I could try it but I don’t think it will do much. One of the sites seems to have just one writer so I don’t think that there are much more people involved.

2 of the 3 sites I found so far that did this are at least linking to my guide. But it is still not great, they should have asked for permission first.
Quartich 15 Sep, 2022 @ 9:34am 
You don't have much legal power of the guide but you can tell the editor of the site that the guide was stolen and provide evidence. They don't have to take it down but they might reprimand the "writer" before they can steal more work.

I found the artikel, it was published six days after my guide. You can see that when you look at the release dates*. The person that published it just copied everything from my guide.
Thank you for telling me, but I think I can't do anything about it.

* My guide was released on 20.03.2022 and the article on 26.03.2022
