One Enough Block

by MerrySnow

One Enough Block lets a pack swap one block for another during world generation, with rules set in a configuration file or a datapack.

ForgeNeoForgeClient and serverGNU General Public License v3.0 onlyOpen source1.20.1 – 26.1.2

What it does

Replacement rules name the block IDs to match and the target block that takes their place. Tag-based matching is also supported, so every block under a tag can be replaced with a single rule. Fluids can be replaced as well as solid blocks.

Replacement happens while new chunks generate, which covers ores, plants and structure blocks. Blocks a player places are replaced at once when they match a rule. Existing blocks in a world can be replaced retroactively, and the feature can be disabled by default through the configuration file. Rules can be loaded from a config file and reloaded with the reload command, or loaded through a datapack. The mod requires One Enough Item, and it is open source under the GNU General Public License v3.0 only. A server running it needs every connecting player to have it too. Files are published for Forge and NeoForge, for 1.20.1, 1.21.1 and 26.1.2.

Key features

  1. Block-to-block replacement

    A rule lists matching block IDs and the target block that replaces them, with no code needed.

  2. Tag-based matching

    One rule can match every block under a tag, so a whole group is replaced at once.

  3. Fluid replacement

    Fluids are replaced by the same rules, so liquids in generated terrain can be changed too.

  4. Retroactive replacement

    Blocks already present in a world can be replaced, not only blocks in newly loaded chunks.

What the author says

Does your modpack have three kinds of orange trees or four kinds of silver ore? Or do you just want to wipe out useless naturally generated ores like copper? With One Enough Block, you can conveniently specify which blocks should be replaced with others — easily, flexibly, and powerfully.
