Seeds are somewhat compatible across editions, with terrain generation and biomes being the same. However, structure locations still remain different between Java Edition and Bedrock Edition.
Whenever the game has to generate a new world, it calls upon an algorithm known as Perlin noise. This algorithm outputs a pseudo-random value that is then used to determine the characteristics and features of the world. However, the algorithm always outputs the same value each time for a constant starting point (seed). Thus, the same seed generates...
In Java Edition, the player can enter the command /seedto view the world's seed. This command is available in singleplayer worlds even if cheats are off. The player can also select 'Re-create' in the Worlds menu to see the seed. In Bedrock Edition, the seed can be found on the world options screen. There are also seed templatesthat offers the playe...
Realms
In Java Edition, a player can type /seed in the chat. In Bedrock Edition, the seed is not visible when playing on Realms.
General
If the seed contains characters other than numbers or is greater than or equal to 20 characters in length, the Java String.hashCode() function is used to generate a number seed. This restricts Minecraft to a subset of the possible worlds to 232 (or 4,294,967,296), due to the int datatype used. Number seeds or a default world seed must be used to access the full set of possible worlds (264, or 18,446,744,073,709,551,616).
Overlap between editions
All Java and Bedrock Edition seeds in the range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, generate the same terrain and biomes in both Javaand Bedrock editions, although with differing structures, decorator placements, carver caves, and mob spawns.
Notable Java Edition seeds
The following map seeds have, at one point or another, been used for generating official Minecraftmaps and resources or otherwise significant community material. 1. The Java Edition demo world seed can be played in the full version by entering North Carolinain the seed input. 2. The PC Gamer demo world seed can be played in the appropriate era by entering glacier, all lowercase unlike the famous seed where the G is capitalized, in the seed input. 3. The seed for each title screen panorama are...

It just needs to know the algorithm and the seed to generate the same world again. The seed is a far more compact way to represent the potential of an entire world, requiring very little data storage. So, Mojang doesn't need enormous amounts of storage for this; the algorithm and the seed do all the heavy lifting! 🌍💡

Oct 12, 2024 · World generation (sometimes abbreviated as worldgen) is the procedural generation process Minecraft uses to algorithmically generate terrain, biomes, features, and thus ultimately decides which blocks are placed where. Minecraft worlds are made of 16×16 blocks wide chunks stretching the full height of the dimension. Because there are more than 18 quintillion (18×1018) possible worlds ...
Jun 5, 2022 · So I know why you’re here: you want to know how that actually works. Sooooo. Minecraft uses congruential generators to seed Perlin noise maps which serve as octaves for fractal Brownian motion noise maps, which are then processed in a layered stack of cellular automaton-like operators to determine the biomes, which ultimately modulate the amplitude of the fractal density map that controls ...

Jan 10, 2024 · Minecraft has cemented its place as one of the few games to continue to grow in users a decade after its original release. While most video games have a shelf-life of less than two years, Mojang Studios’ hit game has acquired new users every year, alongside having bursts of older players returning. Launched in 2009 by Markus ‘Notch’ Persson, a game developer who had previously worked for ...
