What it does

Players mining a survival world often end up with stacks of raw iron, copper and ores, plus common items such as rotten flesh, dirt and deepslate. The mod gives each of these a compressed block form, so a full stack shrinks into one slot. It covers many items and blocks, including foods, logs, dirt variants, stone variants, wool colours, concrete variants, glass variants, hay blocks, clay blocks, regular pale moss and stackable saddles.

The mod is a datapack, built on lightweight ticking functions, recipes and advancements. Server owners and players load it alongside the loader of their choice, and it is published for Fabric, Forge, NeoForge and Quilt. The server must run the datapack, while a client may leave it out. The code is not open source, and the mod is released under All rights reserved. Public links exist for the source code and the issue tracker.

Key features

  1. Compressed block forms

    Common items and blocks gain a denser form, so stacks of ores and dirt take up far fewer slots.

  2. Broad item coverage

    Foods, logs, stone and dirt variants, wool, concrete, glass, clay, hay and saddles are all included.

  3. Recipe-based crafting

    Compression and decompression run through recipes, so the blocks can be crafted and reversed in the usual way.

  4. Planned additions

    The author plans to add more items and blocks, taking suggestions from players for what should compress.
