Lol you're doing it wrong, you can do that with such a small footprint
Look up designs on youtube

redstone logic is like doing math... not worth it.

I mean, I might do like, an automatic door opener or something, but fuck everything else

No, to do what I wanted I specifically needed an XNOR gate, which, combined with the circuitry I needed to make both doors move together (need to give one door a 0 and other door a 1), is a big circuit that needs lots of breathing room to prevent crosswiring.

I can't use buttons because I hate buttons. Doors keep shutting in my face when I use buttons. I wanted it switch operated, but I needed to be able to hit it from both sides, and I didn't want a hole in my wall.

I have had a college electronics class, and it still took me 5 minutes to figure out it was the XNOR gate I needed.

But tbh, binary logic isn't that hard to wrap your mind around. There are only two numbers in it, after all.

One time I did a piston door with an XOR gate (or XNOR, I can never remember which) which was 1 wide and 2 tall, and had a lever on the adjacent wall on either side. I wanted to use buttons, but I figured I would have to add a T flip flop to each input and I had no idea how to do that. I did make it pretty damn compact though for what it was. Of course I only ever made a prototype, and it wasn't actually attached to a building.

Of course I think I was over-thinking it and I could've done the whole thing with a T flip flop right? I basically needed a 2 way RS-NOR latch so that the doors wouldn't crush me and kill me (like they kept doing when I walked through lol) Oh yeah I remember, a T flip flop WOULD work if every time I entered it from opposite sides, but not if I tried to enter it from the same side twice, which is very possible if I had multiple entrances. I needed something that would take either input in any order and be self reseting in one step rather than two.

But I don't actually understand how most of this works, I just have an idea in my head of what I want to happen, a VERY basic idea of what each logic gate does, and I do the actual wiring with tons of help from online and painful trial and error...

I don't even know what xnor means

That was probably an XOR gate, those are simpler. All of the XNOR gates on the minecraft wiki are at least two layers deep.

Alright, it's kind of complicated. This is like a weeks worth of lecture material. 0 means "dim redstone," and 1 means "glowing redstone."

You've got you OR gate, which is exactly what it sounds like. this OR that. You have two inputs, and if either one (or both) is 1, then the OR gate spits out a 1. If both inputs are 0, it spits out a 0.

X is used to mean exclusive. So for an XOR gate, you can have either input set to 1, and the XOR gate spits out a 1. But if both are 1, it gives you a 0. Because it will only take EXCLUSIVELY this OR EXCLUSIVELY that.

N means not. Not basically just means take whatever it does without the n, and do the opposite. So a NOR gate (Not OR gate) will give you a 1 if both inputs are 0, or a 0 if either or both inputs are 1. The opposite of the OR gate.

And then XNOR mashes it all together. It is an Exclusive Not OR gate. So it does the opposite of an XOR gate. If either input is set to 1, the XNOR spits out a 0. But if both inputs are 0, or both inputs are 1, it spits out a 1.

And yes, what I just wrote there is extremely confusing. I hardly understand it. It's easier to explain hands-on, with pictures.

of course, I didn't understand the whole thing. but I think I got a gist of it. depending on with combination of 1 and 0, and OR, or NOR, and depending on X, you get different... you... a glowing... um...






ok yea, I have absolutely no idea

Trust me, you're not supposed to get it that fast. Optimally, I'd spend an hour in front of a chalkboard explaining that, and there'd be tables, and pictures, and it would make so much more sense.

Lightbulbs controlled by two switches are XOR or XNOR gates. With an XOR gate, when both are up, lights are on. Both are down, lights are on. One is up, one is down (in either order) lights are off.

XNOR gate is similar. Both are up, lights are off. Both are down, lights are off. One is up, one is down (either order) lights are on.

(I might have reversed them I can never remember which is which)

So with a door you open it on one side, and then close it behind you on the other. It's just a fancy way of making an iron door or pistons act like an unwired wood door (but with new zombie AI it's necessary to have iron doors now)

See my brain works in a way that I need some kind of example like that to understand it, and then I can understand it just fine. I didn't understand a single word of what Riv just said, but that could be the beer I just had making my brain turn off

Yeah, that's backwards. The plus side, though, you could always pass it through a NOT and get the same result, if you don't mind moving your door over a few blocks. And up a block. lol.

Yeah, without pictures, my education in binary logic is kind of bollocks.

Edit: Hmm... I wonder if I could turn the redstone wires around and put the circuit together under the doors instead of to the side... But this stronghold is so low I might hit lava...

there has to be a faster way to shovel dirt and shit, than just using a shovel or tnt

Y U NO DIG DOWN WITH F3 ON AND MINE AROUND LEVELS 10-16?
Just dig a straight tunnel at level 12 for a few hundred blocks and I GUARANTEE you'll find some.

I once spent 4 days (in RL time) in a cave.... four... days. never seeing the light.

caving has been different for me ever since

DAMN IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I FORGOT TO SAVE MY MINECRAFT FILES WHEN I REFORMATTED...
This makes me so damn sad...

After the first hour of being lost, it's usually a good idea to pick a wall and just start mining up. Make a spiral staircase to the surface.

Once you get to the top, just make a huge 1x1 tower of cobblestone blocks, hopefully you'll be able to recognize your location.

Sometimes, if you're carrying really good stuff, and the place you pop out of looks promising, it might just be a good idea to build a house there. You'll probably find your old home eventually. If you set out determined to find your old place, you'll probably die and have no idea how to find where you died and how to get your stuff back.

I didn't return to the surface because I.... I didn't want to





anyway, what I usually do when I'm lost is I stack up a bunch of dirt blocks until I'm really high up, set the rendering distance to far, and just scout everything out, to see if anything looks familiar

I've learned after a while to just place a 1x1 huge tower right in the middle of my roof of the house. but every now and then, when I go far out, I'll spread out torches.

You hadn't seen the sun in four days... and you didn't want to?

What are you, an FAF administrator?

So, I realized yesterday, using an XNOR gate was completely unnecessary, and a much smaller, simpler, XOR gate would have sufficed.

Oh ho!

I've just discovered a mod called skyblock. You spawn on top of a small block of dirt, floating in midair at about y=64, with no other map at all except for a small block of sand about 45 meters away. The spawn island has;

-A tree
-A chest with;
~a block of ice
~a bucket of lava

and the sand island has

-A cactus
-A chest with;
~A single slice of melon
~Pumpkin seeds
~10 obsidian

It's taking forever to get anywhere, but I'm still doing way better than the guys whose youtube blog turned me on to the mod.

I played skyblock a long time ago back when it was a bit different

It was interesting but got really fucking boring after I had to sit there grinding at the cobblestone generator forever to do anything. Completed all the challenges and everything.
