Features

New compostable items, including rotten flesh, poisonous potatoes, foods, and many more (see the list below).

Important information for versions previous to Minecraft 26.3
Prior to Minecraft 26.3, items could not be made compostable in a fully vanilla way. These items were compostable in the following ways:
  • By putting them in a hopper on top of a composter, the same way you would do with vanilla-compostable items.
  • By dropping them *inside* a composter (vanilla items are also given this feature).
Composting items by dropping them inside composters can be disabled (see the Available commands section)

Known issues (and solutions)

  • Custom-composting via hoppers only works with composters that are placed by players. This means that it won’t work with world-generated composters, with composters summoned via commands, or with composters placed before the datapack was installed. Simply break a composter and place it again manually to make the datapack register it.
  • The datapack might have trouble detecting a placed composter if you are moving very fast while placing it. This shouldn’t be a problem as long as you are not MLG-360-no-scoping composters. If a composter is not working, just break it and place it again while not moving.
  • Some things are hardcoded in this datapack, which means that it can interact in unexpected ways with mods that alter vanilla mechanics:
    • Hopper-custom-composting uses the hopper built-in TransferCooldown variable, so it might conflict with any mod or datapack that changes the vanilla behaviour of hopper cooldowns.
    • Since vanilla-compostable items are hardcoded in Minecraft, I had to hardcode them also in this datapack, so it detects when one of them is present in a hopper and avoids composting other items at the same time. This means that any mod that changes which items are compostable with vanilla mechanics might cause unintended behaviours (but nothing game-breaking).

Adding new compostable items

This datapack provides item tags for 10%, 30%, 50%, 65%, 85%, and 100% composting chances. You can find their .json files in <this datapack>/data/dnv.compost/tags/items/. If you want to customize the datapack for your own use, edit those files however you want.

Available commands

  • /function dnv.compost:uninstall: removes all the entities and scoreboard objectives created by this datapack. Run this function if you want to stop using the datapack to ensure it leaves no trace. All composter markers will be removed, meaning that if you want to use the datapack again after uninstalling it, you will have to manually replace already existing composters in order for the datapack to register them again.
