block _replacer

by mr_ron

With block_replacer, a player can swap chosen blocks within a set range for other chosen blocks, using a tool, a command or both.

FabricClient and serverMIT License1.20.1

What it does

Replacement works in two main ways. Holding a configured tool and right-clicking a block replaces it with the block type held in the offhand while the player is crouching. The command option replaces blocks in a given range with the block type held in the offhand, so a single action can cover many blocks at once. Each tool can be set up in the config with its own range.

The config also sets which blocks may be replaced and which may be used as replacements, so selected blocks can be excluded from both roles. A simple example is replacing a wall of one material with another across a whole area. Creative mode is not required; survival players use the same tools and commands, although the mod's features are most useful when a replacement block is available in the inventory.

Installation needs Fabric. Files are published for Fabric only, for game version 1.20.1, with 1.0.0 as the latest file. block_replacer is released under the MIT License and is not open source. An advancement option can restrict tool use to players who have earned a chosen advancement.

Key features

  1. Area block replacement

    Chosen blocks within a configured range are swapped for another chosen block in one action.

  2. Tool-based replacement

    Right-clicking a block with a configured tool while crouching replaces it with the offhand block.

  3. Per-tool ranges

    Each tool has its own replacement range, set in the config, so tools can cover different areas.

  4. Command option

    A command replaces blocks in a range with the block type held in the offhand, with no tool needed.
