About this Mod
One Enough Block
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.
Main Features
Load Method 1: via configuration file.
Reload using the /reload command.
Path: config/OEB/example.json
[
{
"match": [
"manametalmod:ManaTreeLog",
"#minecraft:logs"
],
"result": "minecraft:redstone_block"
},
{
"match": ["#minecraft:logs"],
"result": "minecraft:redstone_block"
}
]
Load Method 2: via datapack (available since v1.1.0).
Requires OEI as a dependency — note that the structure has changed!
Path: data/oeb/replacements/example.json
[
{
"matchBlock": ["#minecraft:logs"],
"resultBlock": "minecraft:redstone_block"
}
]
Simply list the block IDs you want to replace in the "match" array, and specify the target block under "result".
The replacement will automatically take effect in-game.
Supports tag-based matching, allowing you to replace all blocks under a tag at once.
Even fluids can be replaced!
Note: Since version 1.1.0, an in-game replacement rule editor is built in!
Press CTRL + R by default to open the UI and enjoy a brain-free, zero-code editing experience.(Switch Function -> Page OEB)
Use Cases
Block replacement occurs when creating worlds or loading new chunks, making it ideal for modifying naturally generated blocks such as ores, plants, or structure blocks.
Replacement also applies to any block placement — when a player places a block, it will be immediately replaced if it matches a rule.
Additionally, existing blocks in the world can be replaced retroactively.
This feature is disabled by default, but can be enabled in the config file.
Future Plans
None for now.
