Seed (level generation)

seed level generation 068893

Seeds are values made up of positive or negative characters, including integers, that are used as the basis for generating the Minecraft world.

Compatibility[]

Although seeds are somewhat compatible across editions, with the same terrain generation and biomes, structure locations still vary between Java Edition and Bedrock Edition.

World generation[]

The game calls upon an algorithm known as Perlin noise to generate a new world, using the same seed to ensure that the outputs for each time are always the same. However, this algorithm also outputs a pseudo-random value that is used to determine the features and characteristics of the terrain in the generated world. Thus, the same seed generates the same seed, generating the same value for each time. Whenever a new world is generated in the game, this algorithm is used to determine the features and characteristics of the world.

A world is created when a seed is set. It can be automatically decided, but it can also be manually set. By reusing and setting a seed from one world, the same world is generated. The same world generates the same world. Negatives, including a phrase or a number, can also be included. If a phrase or word is used, it is converted into a 32-bit integer. If a phrase or word is used, it is also converted into a 32-bit integer.

Every time the world generation algorithm is modified (typically by incorporating new biomes into the game), the identical seed no longer produces the identical terrain. If the seed or generator is altered in a saved world, fresh chunks are created based on the new seed and no longer correspond to those generated from the previous seed. Deleted chunks can regenerate if the seed and generator remain unaltered, but will change if either the seed or generator is modified. In fact, the deletion of chunks is occasionally carried out to allow newly-introduced features to appear in an existing world; refer to Tutorials/Updating old oceans in 1.13 using MCEdit.

The relevance of a seed’s value does not result in any relevance in the world.

Determining the seed[]

In Java Edition, players have the option to input the seed, which allows them to observe the world’s seed. This command remains accessible in singleplayer worlds, even with cheats disabled. Additionally, players can choose the ‘Re-create’ option in the Worlds menu to view the seed.

The Edition Bedrock offers several pre-set seeds that players can use to generate worlds with specific features near the spawn point. Additionally, there are also templates available that provide players with various seed options found in the world. The beta version has a visible seed displayed at the top of the screen.

Technical[]

Realms[]

In the Java Edition, players have the ability to enter /seed in the chat. However, in the Bedrock Edition, the seed is not displayed on Realms.

General[]

In order to explore the entire range of potential worlds (264, or 18,446,744,073,709,551,616), either number seeds or a default world seed must be employed. This limitation confines Minecraft to a smaller selection of possible worlds, specifically 232 (or 4,294,967,296), as a result of utilizing the int datatype. If the seed consists of non-numeric characters or exceeds a length of 20 characters, the Java String.HashCode() function is utilized to generate a number seed.

Overlap between editions[]

Despite having varying structures, decorator positions, carver caves, and mob spawns, both Java and Bedrock editions produce identical terrain and biomes for all seeds within the range of -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

By utilizing specific seeds, it is feasible to witness captivating outcomes.

Changing terrain without changing some structures[]

It is possible to create various worlds with similar cave systems, Nether biomes, and other arrangements of generated structures by transforming the seed into binary and adjusting the desired bits. Only particular parts of the seed are utilized to generate specific features in the world. For instance, the seed generator utilizes the initial 48 bits exclusively to generate cave systems and badlands clay banding layers.

Duplicate Caves

Seed 164311266871034 in spectator mode. Caves are repetitive along the Z axis.

Endlesscanyon wideangle

Seed 1669320484 in Bedrock Edition, with repeating canyons.

In Java Edition, when calling the first method with a parameter of 0, it returns a seed of 107038380838084, while calling the second method with a parameter of 0 returns a seed of 164311266871034. These seeds generate infinite arrays and caves structures, causing underwater ravines and mineshafts, respectively, in the internal code. Additionally, the loops on the Z and X axes are involved in this process.

Decorations, such as features in seeds, can repeat and generate diagonally.

1000686894 and -1171867832 are the seeds that vertically repeat the generation of Mineshaft. 1669320484 and 289849025 are the seeds that occur with repetition decoration and dungeon, ravine, cave diagonal in Bedrock Edition.

Any seed computed as 4294967296 × n + 1669320484 also produces maps with recurring characteristics.[7].
