Piston Packing

Piston packing

• When a piston pushes items into a fully enclosed air space, it can compress them into a single block.

• The space must be sealed on all six sides with blocks that have solid sides. If the chamber isn’t fully closed, items won’t compress.

This enables hands-free item processing and storage using only in-world physics and redstone.

Piston shoveling

• The Piston Shovel can be used to break all blocks that a silk touch netherite shovel can break.

Note that only blocks that are registered under the “piston_packing:piston_shovel_breakable” block tag can be broken with a piston shovel.

• The mod itself provides no built-in recipes — all compression logic is defined entirely through data pack recipes.

🧩 Custom Recipes

Define your own packing rules using standard JSON recipe files:

Each recipe describes what items can be packed, how many are required, and what the result should be.

Here’s an example:

{
  "type": "piston_packing:packing",
  "category": "building",
  "ingredients": [
    {
      "count": 4,
      "ingredient": {
        "item": "minecraft:sand"
      }
    }
  ],
  "result": {
    "item": "minecraft:sandstone"
  }
}
