Rotten Flesh Compost

# Rotten Flesh Compost

 

Rotten Flesh is the one mob drop you always have too much of and can do almost nothing with. This mod makes it useful: **drop it into a Composter and it works like any other food item — a 65% chance to add one compost layer** (same tier as carrots, potatoes and melons).

 

## Features

 

– Rotten Flesh is compostable at a **0.65** success chance.

– **Nothing else changes.** All vanilla compostable items keep their exact values — this mod only adds one entry.

– **No configuration, no commands, no new blocks or items.** One tiny data file does the whole job.

– Works in singleplayer and on servers; packs only ~13 KB.

 

## Installation

 

1. Install **NeoForge for Minecraft 1.21.1**.

2. Drop the jar into your `mods` folder.

3. That’s it — right-click a Composter with Rotten Flesh.

 

**Multiplayer:** install it on the **server**. Clients do not need it — the values are synced automatically, so players without the mod still see the correct behaviour.

 

## Customising the chance

 

The mod is driven entirely by NeoForge’s `compostables` data map, so you can override it without touching the jar: put a file at

 

“`

data/neoforge/data_maps/item/compostables.json

“`

 

inside a **world datapack** (data pack format `48`) and set whatever chance you like:

 

“`json

{

“values”: {

“minecraft:rotten_flesh”: { “chance”: 0.65 }

}

}

“`

 

Setting `”can_villager_compost”: true` additionally lets farmer villagers compost it themselves.

 

## Why is the jar so small?

 

Since 1.21.1, NeoForge no longer reads `ComposterBlock.COMPOSTABLES` — composting is data-driven. So the correct implementation is a single data map file, not code. (Which also means the old `ComposterBlock.COMPOSTABLES.put(…)` trick you’ll find in older tutorials silently does nothing on this version.)

 

## Compatibility

 

– Minecraft **1.21.1**, NeoForge **21.1.0+**

– No mixins, no coremods, no other mod dependencies — should be compatible with everything

– Modpacks are welcome to include it
