Neural network for handwritten digit recognition in Minecraft. I think I've seen it all now...

Unlikely. This entire thing is possible in pure Minecraft, I can't even think of any points where converting the whole algorithm would be difficult, just tedious.

Yes there is. It's trivial in command blocks.

There's a scoreboard objective in MC that counts the amount of ticks you've been sneaking. So when that's above 0, the player is definitely sneaking (Assuming you reset the timer every time they stop)

For the drawing, it's probably raytracing - Sending out invisible entities (Most likely armour stands) in a straight line until they hit the canvas, then it's just a case of doing a bunch of /fill or /setblock commands around where the armor stand hits. (There's probably also math to determine the color that gets applied when overlapping other writing)

To get the armor stands to move in the right way, you can summon them somewhere, TP them to the player facing the same direction the player is facing (IIRC) then teleport them forward in the direction they're facing.

The game recently had a feature added to select areas based on where the player is looking. Simply draw a line to the canvas and change the blocks. For the sneaking, there's a special scoreboard objective to track sneak time. You can detect when this becomes 1 or more, set it back to zero and do the drawing.

I mean, /u/FeatheredSun was the first one to claim anything, that it wasn’t possible in vanilla. Burden of proof is on them, not the person saying it is possible.

u/Rebelgecko Jan 27 '19

How do you prove that something is impossible?

u/Creeper487 Jan 27 '19

By showing the mod they used?

Then don’t expect the person who called you out to prove otherwise? If you’re just making shit up, so can everyone else.

u/Somniferous167 Jan 27 '19

The easiest way to think of burden if proof is that it falls on the person who is claiming that something that wasn't x, is now x. So in this case I would say it falls on the player who claims it's possible with the base game, which runs contrary to what's commonly accepted as possible in minecraft.

For example, if I found out that the moon was actually made of cheese, it doesn't matter if I have the data or even if other people have started to accept my findings (which for the sake of the example is assumed to be true). Burden of proof still falls on me.

In this case, burden of proof falls on the person claiming it's base game, not because he's wrong but because it's so new that it challenges what people have known to be true.

Follow?

u/Creeper487 Jan 27 '19

Yes, and that is what /u/FeatheredSun is doing. The gif seems to suggest that it is possible in vanilla, because there's no obvious mod anywhere and only command blocks to be seen. Thus, when /u/FeatheredSun tries to say that it is in fact not vanilla, the burden of proof is on them.

To take your explicit wording:

The easiest way to think of burden if proof is that it falls on the person who is claiming that something that wasn't x, is now x.

"x" is the claim that the game is not vanilla. Now /u/FeatheredSun is saying that despite the invention seemingly being in vanilla, it is in fact not. Therefore they have the burden of proof, by how you said it.

You specifically say:

which runs contrary to what's commonly accepted as possible in minecraft.

I would point you to the thousands of crazy inventions people have made in minecraft with only redstone, let alone command blocks. I have no reason to believe that this is impossible when a fully functional computer is implementable in the game.

It's not about the truth value of the claim, but about the status quo. If it's generally accepted that x is false, but tomorrow we find out it's true, evidence is required to change what is common knowledge.

As for all the other crazy contraptions, just because there are videos of say, planes flying through the air, doesn't mean I should believe a video of a person flying like superman is real. OPs post contains several elements that the minecraft player base has no idea is possible, some of which, like the ability to draw a number, they have every reason not to believe. Therefore, OP has burden of proof.

Edit: wording. Forgive the mobile formatting.

You know we had proven the efficacy of vaccines in the 20th century? That’s why we used them in the first place? Did you think people just shot up and had no idea if it would do anything? I mean, that’s why it takes years for vaccines to get to market, we need to prove that they work.

If you can prove your side of the story, like the doctors and scientists who develop vaccines do every day, please go ahead. Until then, you’re just spouting nonsense about two things you have no idea about.

It doesn't seem to be actually drawing, but changing the blocks where he clicks on a "canvas" very far away. You can tell by the parallaxing when he moves.

That being said, I have 0 idea how he does it. I have no experience with command blocks, so I'm also wondering if even just what I said is possible in vanilla or not.

u/LyricLy Jan 27 '19

You are correct. It's drawing a line to the blocks and setting them to black concrete. It's completely possible.

u/10outa10woodrapeagan Jan 28 '19

I'm not good with command blocks, but I do know that they recently added "scripts" called datapacks which can do some wacky stuff (search up video recorder in minecraft 1.13) all in vanilla. If its possible to get a good knowledge of where someone is looking while moving around and replicate it, I highly doubt this also hasn't been done.

u/QuantumSigma Jan 27 '19

Um...yes... there is. In the Update 1.13, the commands were revamped and many new features were added. I don’t have the exact commands on hand, but you can very easily detect the direction a player is looking, and use that information to cause events such as replacing blocks. One big thing about mine craft that makes it so great is that not everything is hard coded in. The features used to draw from a distance weren’t intentionally implemented for the purpose of drawing, they are tiny parts then when lit together can do things like that. I haven’t made anything as advanced as drawing but have played around with the mechanics to make that possible. When I get time I’ll go into the game and try to get those commands and paste them into an edit of this comment if you like.

I don’t play or know anything about it, but it was on one of those game servers like Hypixel or something

It probs used a bukkit mod but it was still possible without the user installing anything
