Simple and well optimized UUID based RNG.
  • Supports values from 1 up to 100000000 (one hundred million).
  • Can be used both as a server utility and a library for other datapacks
  • English and Russian locales for built-in messages available.
  • No idea how well distribution is, but looks fine for me :D

Commands
/trigger roll set <max-value> - generates a random number up to <max-value> and broadcasts result.

/scoreboard players set <entity> roll - sets max value for any entity. For players it rolls instantly.
/function droll:user/roll - rolls a dice with set max value. Works for any entity. If max value is not set - result could be anything.

/scoreboard players set Server roll <max-value> - generates a random number up to <max-value> and broadcasts result as Server. Does not require any entity.

/scoreboard players set Locale DROLL.System <id> - Sets locale for broadcast messages. 0 is English (default) and 1 is Russian.

/function droll:uninstall - uninstalls the datapack (deletes all linked scoreboards)




For datapack developers
/function droll:lib/random - generates a random value. Value can be negative and stored until next RNG call.
/scoreboard players get Random DROLL.Random - get value generated by droll:lib/random


/function droll:lib/random_capped - generates a random value up to Max. Value is stored until next call.
/scoreboard players set Max DROLL.Random <max-value> - sets max value for next droll:lib/random_capped call.
/scoreboard players get RandomCapped DROLL.Random - get value generated by droll:lib/random_capped.


Delete "droll/user" folder in datapack if you dont need any built-in user commands with broadcasts. Uninstall datapack before deleting folder.

Datapack example usage
<...>
scoreboard players operation Max DROLL.Random = Player MaxRoll
function droll:lib/random_capped
scoreboard players operation Player OutputValue = RandomCapped DROLL.Random
<...>
<do your things>


System uses entity UUID for RNG, so it will be much less effective in a world with no entities spawning. Non-living entities do also work tho.

Datapack should work on any version since 1.13, but I have only tested it on 1.17.1 and 1.20.1 cuz other versions require different Java. Tell me if it doesn't work on your version.
