The Powder Toy

My First Mod: Logic Gates

  • iamdumb     21st Aug 2014 Member 6 Permalink

    TPT Logic Gates Mod

    Elements Added

    AND: SPRKs nearby NSCN when powered by 2 or more PSCN

    OR: Conducts from PSCN to NSCN

    NOT: SPRKs nearby NSCN unless powered by PSCN

    XOR: SPRKs nearby NSCN when powered by ONE PSCN

    NAND: SPRKs nearby NSCN unless powered by 2 or more PSCN

    XNOR: SPRKs nearby NSCN unless powered by ONE PSCN

     

    Lua Source: http://pastebin.com/HM3LuEps

    How to use

    Simply save in your Powder Toy folder as tptlogic.lua (or another name) and in the TPT console (~) type dofile("tptlogic.lua")

     

    Changes

    • Gates now work in all directions
    • Changed NOT gates
    • Corrected Element descriptions, corrected some conditions. 

     

    Just one thing, I'm not sure what the 'nt' argument for the update function is for, so I ignored it. Could someone please inform me of it's purpose?

    This is pretty cool, but I have noticed a couple of things:

     

    • AND, OR, NOT work fine, but NOT bugs sometimes.
    • XOR seems to be completely unaffected by the amount of PSCNs powering it, it conducts with any number (I understood it as 'there is exactly one PSCN powering it'. Am I wrong?).
    • The condition for NAND seems to be > 2, not >= 2, that is over 2 PSCN are needed. Just like NOT, it isn't very reliable.
    • XNOR is also pretty chancy (Looks like all gates that continuously spark have this), but other than that, it's fine.
    • Some logic gates interfere with others' performance, despite being a big distance apart.

     

    Also, not that this is a big deal, but the description for XNOR is the same as for AND. :P

    I corrected that :P. Probably a typo.

     

    Thanks for the feedback.

    I've made the NOT gates a bit more reliable now.

    Why doesn't it work horizontally ? am I doing it wrong ?

     

    Anyway, your first mode really is awesome/amazing/cool, you really did some work on that. I didn't expect to see you do something like that, lol.

    Erm, no. That was me being incompetent with Lua. It should work in all directions now.

    The XOR gate acts like a normal OR gate, but besides that, it works fine. It is a great mod, especially for your first.

    This is cool! Gonna download it

    This mod is amaze, use it all the time!

    Unfortunately, at least the NOT gate (not sure about the others) can only be used one at a time. If I try to place a second NOT gate, it doesn't work until I place it while the other one isn't spawning an electron and then the other NOT gate stops working.
