I don't need help with any scripts, I was just curious on how you would make an XOR or XNOR logic gate. An XOR logic gate is an “Exclusive OR”. If two or more inputs are 0 or 1, the output is 0, but if only one of the numbers are 0 or 1, and the rest are the opposite, the output is always 1. An XNOR logic gate is an “Exclusive NOT OR”, which inverts the XOR logic gate. How would I replicate this in Scratch?

Lol you gotta love logic gates. I’ll send you some code for it later ok? I’m on mobile rn

XOR

if <<<(Input 1) = [1]> and <(Input 2) = [0]>> or <<(Input 1) = [0]> and <(Input 2) = [1]>>>then 

set [Output v] to [1]

else
set [Output v] to [0]
end

Actually, I was doing IT homework and remembered about a similar language based on Scratch that had it, and since there is no such block in Scratch, perhaps there would be some way to do it.

Ok I’ve done XOR for you

Thanks! I'll check if it works. I was kind of already assuming that's how you do it, but at least people will get to see this forum and get their question answered.

XOR not(a=b)

If you use 0 for false and 1 for true XOR just means the sum is 1. So the inverse if if the sum is not 1.

You could just add them

if <((Input 1) + (Input 2)) = [1]> then 
set [Output v] to [1]
  

else
set [Output v] to [0]
end

But that seems less like a logic gate and more like addition - logic gates are sometimes used to do addition, so it’s sort of cheating if you used addition to do the logic gates, but it’s much quicker

use

<<<<x> or <y>>> and <<not<<<x> and <y> >>>>>

for xor and just add a not for xnor

whoops about the red background
