Java's UUID.randomUUID() function performs this exact task.So you want to play Minecraft with your family, but you only have one account. Minecraft uses version 4, variant 1 (RFC) UUIDs, which means that the entire number with the exception of the bits used for metadata (version and variant) is randomly generated. 110 is the "variant 2" of old Microsoft products.10x is the "variant 1" of IETF RFC 4122 (Leach-Salz).0xx is the "variant 0" of Apollo NCS 1.5, an old type of UUID.Depending on the specific variant, it may occupy the high 1 to 3 bits: The "B" position is the variant (format) of the UUID. The "version" value occupies four bits, and is located in the UUID string format at the position indicated by an "A". Versions 1 and 2 are based on current time and MAC address versions 3 and 5 are based on hashing a string version 4 is based on completely random generation. (The names make sense only for version 1 and 2 UUIDs, but it has been passed onto all forms of UUIDs used.) Hyphenated hexadecimal format UUIDs follow the pattern xxxxxxxx-xxxx-Axxx-Bxxx-xxxxxxxxxxxx. Hyphenated hexadecimal format section names It is important to note that this evaluation does not refer to the range of values generated by the game but instead focuses on the capacity of the format. Identifier of the entity that the player is ridingĪ UUID can be expressed as a 128 bit number, which means that it supports all integer values from -(2^127) to (2^127)-1. Player who is converting the Zombie Villager Set UUID of modifier in set_attributes function Used when equipping and unequipping the item to identify which modifier to add or remove from the entity. The following table represents the situations in which UUIDs are used in places accessible by a player: Each part is stored in an integer array ordered from most significant to least significant.Īn example of this representation would be Int-array: A separation into four 32 bit numbers.This format is deprecated as it was used before 1.16 and was entirely replaced by the Int-array format.Īn example of this representation would be UUIDMost:-568210367123287600 paired with UUIDLeast:-6384696206158828554. Each of the two numbers is stored separately and uses the Long data type in the game. Most/Least: A separation of the 64 most significant bits from the 64 least significant bits.Hexadecimal: The same as the hyphenated hexadecimal representation, but without the separation of the different sections.Īn example for this representation would be 00000001000200030004000000000005, where it is impossible for the majority of empty digits to be removed as opposed to the hyphenated hexadecimal representation.Because every part is evaluated as an individual number, empty digits at the start of a section can be ignored.įor example, 00000001-0002-0003-0004-000000000005 can be evaluated as the same as 1-2-3-4-5.Further detail follows in the Technical aspects section.Īn example of this representation would be f81d4fae-7dec-11d0-a765-00a0c91e6bf6. The hyphen are set to split the UUID into numbers of the format 8-4-4-4-12 with each number marking the number of hexadecimal digits fitting into the corresponding section. Hyphenated hexadecimal: A hexadecimal representation of the UUID, with hyphens separating the different sections into individual numbers.3.2 Hyphenated hexadecimal format section names.
