Features

General

The Block Compressor is a machine that compresses and decompresses items on top of it. Compressed items enable containers like chests and shulker boxes to hold vastly greater quantities of items.

Compressed items can easily be decompressed back into their original state to be used in crafting and building. Be careful though, if a compressed item is placed as a block it will lose its compressed state. For example, if a *64 compressed diamond block is placed on the ground, 63 diamond blocks will have just been lost.

A Block Compressor

Crafting

The Block Compressor can be crafted in a Custom Crafter using iron, purpur, obsidian, and pistons.

Compressing and Decompressing

The GUI of a Block Compressor is used as a settings interface for the type of compression it will do. A Block Compressor has 2 modes: compression and decompression. Compression mode is set if an item with a stack size greater than 1 (e.g. 16 or 64) is in the Compressor, while decompression mode is set if a single item (stack size of 1) is in the Compressor.

Once Block Compressors mode is set, throw items on-top of the Compressor to compress/decompress them.

Compression Process

Compatibility

Compressors can be moved with Relocators.

Technical Details

A chest full of *64 compressed items can hold a total of 110,592 items, 6400% more than a chest of uncompressed items (1728 items).

A chest full of shulker boxes, each full of *64 compressed items, can hold 2,985,984 items.

A block compressor will do 1 compression per 16 game ticks, 8 redstone ticks, or 0.8 seconds.

Advancements

Advancement	Requirement
Clever Crushing Make yourself a Block Compressor	Have a Block Compressor in your inventory
A Compressed Diet Eat too much of everything. This can't be good for you...	Eat a max compressed item of each food item. Uses the same list as A Balanced Diet, but excludes the soups/stews and enchanted golden apples. Most items must be 64x compressed, however honey bottles must be 16x compressed, as their max stack size is 16.
