This preview version adds data-driven brewing recipes with a recipe book and moves attribute modifiers on items outside of the item behaviour.

For a few more details regarding the split and future you can look at the roadmap to 1.21!

Changes

Assets

• Added four textures for the Brewing Stand recipe book filter button.

Items

• Added new item tags:
  • #minecraft:brewing_inputs, which is used for the accepted items for the Brewing Stand input slots.
  • #minecraft:mundane_potion_additions, which is used to convert Water Bottles to Mundane Potions in a brewing recipe.
• Added an optional attribute_modifiers field to the item.
  • Its value is the same as the list form of the minecraft:attribute_modifiers data component.

Item Behaviour Components

• Removed minecraft:attribute_modifiers.
  • Entries should be moved to the attribute_modifiers field on the item.

So if you had this:

{
  "behavior": {
    "minecraft:attribute_modifiers": [
      {
        "id": "example:tool.heavy",
        "type": "minecraft:gravity",
        "amount": 0.01,
        "operation": "add_value",
        "slot": "hand"
      }
    ]
  }
}

You now have to use this instead:

{
  "attribute_modifiers": [
    {
      "id": "example:tool.heavy",
      "type": "minecraft:gravity",
      "amount": 0.01,
      "operation": "add_value",
      "slot": "hand"
    }
  ]
}

• Removed minecraft:armor.
  • Entries should be moved to the attribute_modifiers field on the item.

So if you had this:

{
  "behavior": {
    "minecraft:armor": {
      "attribute_id": "minecraft:armor.chestplate",
      "defense": 8,
      "knockback_resistance": 0.0,
      "toughness": 2.0
    }
  }
}

You now have to use this instead:

{
  "attribute_modifiers": [
    {
      "id": "minecraft:armor.chestplate",
      "type": "minecraft:armor",
      "amount": 8.0,
      "operation": "add_value",
      "slot": "chest"
    },
    {
      "id": "minecraft:armor.chestplate",
      "type": "minecraft:armor_toughness",
      "amount": 2.0,
      "operation": "add_value",
      "slot": "chest"
    }
  ]
}

• minecraft:brewing_amplify
