Survivalcraft Goes Analog

The new functionality of electrics in Survivalcraft that I was talking about is analog signals.

For those who don’t know, a digital signal can only have 2 levels: low and high. This is what we had in Survivalcraft before 1.23. Analog signal on the other hand is smooth and can have any level between low and high.

One can transmit a lot more information with an analog signal than with digital. While a digital signal always carries one bit, analog signal carries as many as we can extract from minute differences in voltage level. For practical reasons, I limited Survivalcraft to 4 bits. That means the analog signal has 16 distinguishable levels.

On the other hand, digital signals are a lot more resilient to interference and easier to work with – that’s why pretty much everything in the real world has moved to digital. But these advantages do not have any importance in the world of Survivalcraft, where there is no interference :-)

The inevitable question is, why do it?

Less wires to carry the same information. And this is not just a matter of convenience. By principles of geometry, devices in Survivalcraft are limited to 4 or 5 inputs. If all of these are used, the devices cannot be placed near each other because the wires sticking out of the sides get in the way.

SideBySide

Only one wire can be used for devices which need to be next to each other – the one that enters at the back of the device.

That’s one reason. Another reason is that real life phenomena are analog. Weight. Speed. Distance. Brightness. They can be perfectly well transmitted as a single analog signal instead of encoding them as multiple digital ones.

Here’s a video showing some of the new elements in action:

      And also add cars, or trains, or any type of transportation instead of horses and donkeys.

    Awesome!

    Again. I think if the motion detector will react to the sand, it will be a great addition.
    And so are you, Kaalus, said that doing shaders, but in the video they do not, why?

    This reminds me about the “Time Bomb” level I downloaded a few months ago

    Are led lights going to be in more colours too?

    Please add villages and multiplayer. More interaction in the game would be a huge plus!

    You can call it analog if you want but I’m going to call it a 4-bit digital bus. :)

    Any possibility of force-loaded chunks (i.e. A specific chunk with a bunch of electronics that a player wants to be loaded no matter where they are) in any release?

    Add cat and dog!

    Kaalus – Adding “Analog” is a great feature, but it got me thinking about wireless transmission, such as a radio transmitter and receiver that pair up for a short distance. This would add a feature that will allow player to not just hide cables to switches but build even more complex devices and traps. Have you considered this kind of device yet?

    Love it!

    THIS WILL BE PERFECT FOR DISCOS! Plus, now this means the random generator can be used for this as well! I can’t wait!

    When are you going to update the survivalcraft updates app? (Its still stuck in 1.22)

  27. Posted September 29, 2013 at 17:38 | Permalink | Reply

    Maybe you changed the mechanics of the lever? It must be a switch and not the power source.

  28. Posted September 29, 2013 at 20:12 | Permalink | Reply

    Does this mean PWM? I didn’t see an example of that in the demo bid but I bean come on analog electricity must have PWM imagine the possibilities!
