UntraceableSeed

For new worlds, generation reads the seed mixed with a secret kept only in the world's save folder, so the seed alone no longer rebuilds the world. Mouse-made seeds, bedrock kept apart, /seed restricted. Optional on client and server.

What's new

First public release for Forge 1.20.1 (replaces the earlier upload of the same version).

  • A server with no world always asks for the randomness: an administrator with the mod chooses the seed and the generation on a screen (mouse movements), or the console sets a seed. Works on hostings such as BisectHosting.
  • The chosen seed is no longer written into server.properties, so a world deleted later is asked for again.
  • /untraceableseed newworld replaces a world that has no secret of its own; nothing is ever deleted, old folders are renamed.
  • Every new world has its own secret mixed into its whole generation: Overworld, Nether, End and other mods' dimensions (Twilight Forest, Aether, Undergarden, Bumblezone, Ad Astra and more).
  • Only a closed list of generation readers gets the mixed seed; every other mod and /seed see the stored seed, so mods that read the seed keep working and terrain is not broken.
  • Worlds made with earlier builds keep generating exactly as before.
  • Twilight Forest and Voidscape keep their own copy of the seed for the whole session.
