Compressed Box
by iglee42
Compressed Box lets players pack a chunk-sized area of a base into a single block, so a build can be kept loaded and filled with items and fluids from hoppers and pipes.
What it does
A compressed box is a block that holds a whole area of the world. Players set an entry point inside it, build freely there, and leave again. Boxes can be renamed, exported as a schematic, and tuned through client settings. Each box is kept loaded through a chunk loader; the standard loader needs charging with glowstone to work correctly, while the infinite variant does not. Because the box is always loaded, machines inside keep running while the player is elsewhere.
A block linked to a box acts as an interface. Its item slots store items inside the box, and hoppers or pipes can insert into them directly. Its tanks do the same for fluids, which can be added with pipes or by right-clicking with buckets. The mod is inspired by Compact Machines and Hyperbox, and it is intended to help build compact spaces where everything a player needs can sit in one place.
Compressed Box requires Architectury API, Fabric API and oωo (owo-lib). The server and every player need the mod installed. Files are published for Fabric, Forge and NeoForge for 1.20.1 and 1.21.1, and the code is released under the MIT License as open source.
Key features
Entry points and renaming
Each box has an entry point that players set, and boxes can be renamed to tell them apart in a large base.
Schematic export
A box can be exported as a schematic, so a configured space can be copied and placed again elsewhere.
Item and fluid interfaces
A block linked to a box exposes item slots and fluid tanks that store contents inside the box.
Hopper and pipe insertion
Hoppers and pipes can push items into the linked slots and fluids into the tanks without manual transfer.
Leaving a box
A player can leave a box at any time and return to the surrounding world at the place they entered from.
