Reliable Replacer

# Reliable Replacer A lightweight utility for replacing one block with another, both during worldgen and afterward. This mod allows modpack creators to effortlessly ban items or restrict their usage using standard JSON files, without the need for complex scripts. ## What About [Block Swap](https://modrinth.com/mod/block-swap)? I'm glad you asked! I made Reliable Replacer because of some of my personal frustrations with Block Swap. Here are some reasons to consider switching! Why Reliable Replacer? * Reliable Replacer is frequently updated and supports the latest versions, while as of the time of writing this, Block Swap is stuck on 1.20.1. * Live config reloading! Run `/reload` and see your changes instantly take place. * Reliable Replacer is fully server-side, so it's compatible with Vanilla clients! * Advanced filtering: * Filter swaps by biome, dimensions, placed feature, coordinates, or structure! * Toggle retrogen on or off _per rule_. * Toggle player placement replacing _per rule_. * Much more flexible configuration, supporting simple JSON configuration in user-defined folders and integrating with Cloth Config. * Per-rule toggleable persistence: * Decide if replacement blocks should inherit the properties of the old block. * Doesn't require any external libraries. ## Migrating From Block Swap Making the switch is easy! Reliable Replacer supports a legacy format designed to work exactly like Block Swap's configuration. When you first launch the game with Reliable Replacer installed, a `swapper.json` file will be automatically generated in your `config/reliable_replacer` folder. This file uses a simple key-value pair format identical to Block Swap. To migrate, simply copy the "swapper" block from your old configuration into this file: ```json { "swapper": { "oreganized:lead_door": "supplementaries:netherite_door", "farmersdelight:rope": "supplementaries:rope", "minecraft:dirt": "minecraft:stone", ... } } ``` *Note: Rules defined in `swapper.json` automatically inherit default settings (retrogen enabled, replace on player placement, etc.). For more advanced control, use the standard rule format.* ## Features A full feature list is available on the [Modded Minecraft Wiki](https://moddedmc.wiki/en/project/reliable-replacer/latest/docs/reliable-replacer/features). For information and examples on how to use the mod, please also refer to the [wiki](https://moddedmc.wiki/en/project/reliable-replacer/latest/docs/reliable-replacer/usage). ## Quick-Start Example Create a file called `my_replacement.json`, or whatever else you'd like, in `config\reliable_replacer`: ```json [ { "inputs": [ "minecraft:dirt" ], "output": "minecraft:diamond_block", "biomes": [ "minecraft:plains" ], "min_y": "-30", "max_y": "64", "player_blocks": "true", "keep_nbt": "true" }, { "inputs": [ "minecraft:stone" ], "output": "minecraft:gold_ore" } ] ``` ## License [](https://github.com/evanbones/Reliable-Replacer/blob/1.20.1/LICENSE)
