  • The Unsolved Mystery of Minecraft's Identical Worlds -
    Minecraft worlds are theoretically infinite, or 30 million blocks in all directions. That's a lot of blocks and a lot of chunks. Out of all the possible combinations of blocks in a chunk, and chunks in a world, could there be two seeds in which two identical chunks appear? Or even cooler, what if two identical chunks appear in the same Minecraft world? Is it even possible? Can two Minecraft Worlds be the same? Well, yes. maybe. :)
    Seeds:
    Repeating Caves: 164311266871034
    Infinite Mineshaft: 107038380838084
    'Identical' One: 6444932541743890431

      I think there are a lot of people whis whom you share, as there are only 16*16*256*5000 possible arrangements of blocks in the chunk (may be some more, depending on dimension and Biomes) that is about 3.27*10**8, and a lot of this arrangements are impossible or rare (for example chunk full of chests or diamond blocks), and there are 5*10**8 people who play Minecraft, and all of them created at least one world, and thousands of chunks, so at average every chunk was seen 10 thousand times. Of course i didn't take into account that there could be much more arrangements if we will try to find not only blocks but things inside chests, but i,m almost certain that even in that case most chunks was seen not only one time

      @Chonghan L As someone who started out with Java as my first programming language, I have a hard time understanding how it could traumatize anyone. To me, it's the best programming language I've ever programmed in. There's just something incredibly satisfying about applying object oriented paradigms in a way that makes sense and feels natural.
      Then again, it's understandable if it's on your list of things you suck at. (Which there's nothing wrong with. Everyone has a list of things they suck at.)

      @@BlueSodaPop_ Most Java courses and learning books don't explain OOP until rather late, despite the fact it's a fundamental part of the language, and that might be what confuses people. I was lucky to have learned it with Greenfoot initially which follows a different approach: Before even explaining the basic code statements, it first discusses the idea behind OOP. That idea weaves through the entire course, in particular regarding modularity. This makes the chapter about classes much less of a "we introduce a whole new pattern that changes the way you code completely and that you probably noticed the whole time but never knew what it was all about" and more of an "ok, but how do you actually do OOP?", which to me feels much more consistent.
      That approach does have its downsides, though. When I subsequently studied Computer Science at the UAS, I was constantly using OOP for things where it makes zero sense (such as an entire class hierarchy to create String messages to print) and thought that's how you're supposed to do things. I learned that part rather quickly, however. Mere 2-3 semesters later, my code from early 1st semester felt embarassing to look back at.

    When he mentioned the pigeon hole thrown he was close. The problem was he focused on chunks rather than what generates chunks. Chunks are determined by the seed of the world, Minecraft works by hashing your seed, there's an "infinite" number of things you can input for a seed but they all get converted into a specific number using this hash function. Because there's an infinite domain and a finite range this leads to multiples of the same input mapping to the same hashed value, this is what's known as a hash collision.

    The entire part of can there be the same chunk in the same chunk on two different seeds is always a yes. It is called sister seeds that share all the same loot and structures (and biome(s) to a %). For every world you make there are 2^16 -1 other seeds just like that one (that's 65535
    seeds). Sisters are used a lot when finding the perfect seed for speedrunning. The same chunk in different coords is interesting and currently unknown. Also just as a note: sister seed is not a shadow seed, they are 2 completely different things.

    • @annaw.1951
      @annaw.1951 3 роки тому +44

      Just thought I'd add some details here: Minecraft uses Java's built-in random number functions to generate structures and loot, but some other algorithm (perlin or simplex noise, I believe) for terrain.
      Java uses a linear congruential generator with a 48-bit seed to generate random numbers. The seeds you provide to Minecraft are 64 bit.
      What this means is that the structure generation essentially "cuts off" the highest-order 16 bit of the seed and uses the remaining 48 bit to generate structures, but the terrain and biome generation still uses the whole 64-bit seed. Note how the two seeds Wifies shows that have the same structures only differ within the first 16 bit. When he changed 8 random bits, he didn't take any care not to change the lower 48 bit, so the structures were different.
      This means that there are 65536 times fewer possible structure seeds than there are world seeds. Consequentially, there will always be sets of 65536 seeds that share exactly the same structures.

      But by terrain generation noises and equation
      Two seeds having same block in same x,y,z coords has percentage

    so the last few numbers or so of a seed when converted into binary are what define the structures, the former characters are what define the biomes and what not, so if you add 2^16 to a seed, you'll get a "sister" seed, they have the same structure generations but different biomes. this strategy was used in the 1.8.9 SSG speedrun to find the most optimal seed for the run.

It's not really common to see gaming youtubers using their own calculations as backup to their theories and as further and clear explanation of how the game system genuinely works. It's good to see someone who can start from pure facts and build something strong only from them.

  • @BrodieEaton

    I'm actually strangely knowledgeable in the area of infinite terrain generation, although the jargon in IT is "progressive terrain generation" since it's not actually infinite, it just progresses as the player progresses. Although I don't know exactly how Minecraft does their progressive terrain, there is some technical knowledge I can supply, and hopefully I'll be able to help solve the mystery shown at 6:00.
    For starters, the surface of the world is generated using a type of visual noise known as "Perlin Noise", used to generate visual black-and-white noise that transitions smoothly between minimum and maximum values. This noise script is added onto itself as many times as the developers choose to generate Fractal Noise, to give smaller details on top of the larger shape. However, this type of script has one fatal flaw, being that every single instance of Perlin Noise is identical; you can't have random Perlin Noise.
    So, what developers do to get around this is they randomise where the Perlin Noise is initially sampled from, and these values are so high that it might as well be random Perlin Noise. When it comes to fractal noise, each layer of Perlin Noise (aka each octave of Perlin Noise) is sampled individually from the other layers, allowing each layer to be sampled from entirely different locations, providing more randomness to the terrain. The easiest way to accomplish this is to just put the world-seed into a random-number generator to spit out an x-offset and y-offset for each layer of Perlin Noise. Then, to turn the shape of the fractal noise into an actual 3D surface, each value within the perlin noise is interpreted by Minecraft's code as a value between 0 and 255, with interpretations being different depending on the biome the values are being interpreted in.
    Now, with all of this knowledge presented, I'm going to show you why these two worlds were completely identical at these specific coordinates and why there are probably many more coordinates in these worlds that are identical, and it has to do with the way that random number generators actually work. For starters, there is no such thing as a "random number generator". They're actually "pseudo-random number generators", with "pseudo-random" meaning "fake random". While I won't go into detail on how they work, RNG is nothing more than basic mathematics with really large numbers outputting relatively small numbers, to make the outputs look random. Which means the same input for an RNG script will give the same output. The other thing to know about RNG is that each output it generates will always become the input the next time it's called, unless the code changes the input directly. It is very possible that two numbers, when put into the same random-number generator, will output the same number. And, since that output becomes the next input, the second, third, fourth, fifth, and every other number that is generated by that random number generator will be identical, until the input is directly changed by the code. If you were paying attention earlier, you might be able to piece this mystery together now.
    Like I said before, the sampling of Perlin Noise is offset randomly using a random-number generator, where the world-seed is the initial input. So, what has happened here is that these two seeds, when put through the random-number generator, outputted exactly the same result for the first time it was called, meaning every other time this random-number generator was called outputted the same numbers for both seeds, giving both of the worlds exactly the same Fractal Noise. That's why they were identical when you got to those coordinates. Which then raises the question as to why it was only at these coordinates that the worlds were identical, but if you were paying attention earlier you'd probably know that too, and it has to do with the biomes. Like I mentioned earlier, each biome interprets the fractal noise differently, so that the surfaces of different biomes generate differently to each-other.
    I have no clue as to how Minecraft's biome-distribution works (although I'm beginning research on biome distribution shortly), but what's happened is these biomes just so happened to be identical at these coordinates. And, since the fractal noise for both worlds are identical, and the biomes at this location is identical, the surface for both worlds were generated identically at this location. The ores, grass, caves, trees and ruined portals, are probably also generated with a similar process using RNG, which is why these were also identical at these location.
    Theoretically, so long as the biomes for both worlds are identical at a certain locations, there could be so many more locations within these worlds that are identical. I'd suggest going to the ChunkBase Biome Finder and trying to find some coordinates where the biomes in each world are identical. I just found a point at X -6378, Z -12297 if someone wants to give that a go.

  • @Julianiolo
    @Julianiolo 3 роки тому +10

    For everyone that's confused about the binary stuff:
    He is right, there is an interesting pattern behind them
    The seeds in binary are (binary is just a way of writing a number with just 0 and 1):
    0101 1001 0111 0000 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 and
    0111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111
    Both are 64 "places"(called bits) long.
    The special thing is that both seeds only differ in the first 16 ones and zeros (technically 15 bc of the 0 in the start), the rest is all 1.
    The second one is because of all the 1s the biggest number you can write (with 64 many 0s and 1s).
    The third thing is that the 1st place is always 0.
    Thats also why i think the possible number of seeds with this pattern are not 2^16 = 65536, but infact probably only 2^15 so 32768. That is just speculation on my side though.
    The last 48 bits of the number are the same.
    Minecraft uses all bits for the terrain generation, but only these last 48 for generating structures, which is likely the reason the last 48 bits are the same.

    I remember on the pocket edition days when my cousin gave me a seed called "villagepls" and found an oak village connected to a sandstone village, I didn't know that a few PE players use the same world but a different seed

      Do you know seed 999? I remember it used to be different villages if the mode for worlds are different (from what i mean modes its like infinity, old and flat) and i was shocked when someone was playing on that seed. Good times

    I remember before the redstone days on Minecraft PE, I had loaded up an Old type of world. A couple months after I had made an Infinite world (different Seed) but I was greeted with the same exact world as the Old world, but Infinite. That was one of the only cool things I remember and wish I still had.

    I think this is simply a case of subseed overlap. (instead of directly using the world seed for every chunk (which could really slow things down), every chunk gets an x/y adjusted derivative seed to work with ... which can result in two unrelated world-seeds getting at least one shared 'chunk-seed')

    I'm no expert, but maybe the two identical chunks have something to do with 9223372036854775807 being the 64-bit integer limit?

    “This Minecraft world is identical to a world you’ve already seen” is where I got spooked a bit because yes, that was, quite literally, a world that looked pretty much identical to one that I have loaded up on my own computer
