About this project

What does Unbreakable Library add?

A tag-driven datapack library (1.21+) that makes tagged items truly unbreakable. This pack does nothing on its own. Install this example pack along-side it for something to happen. The example pack makes diamond and netherite gear, and the mace unbreakable.

For Developers

To make custom items unbreakable, create a datapack that adds the item id to the #unbreakable_library:unbreakable item tag.

{
  "replace": false,
  "values": [
    { "id": "namespace:item_id", "required": false },
  ]
}
