Oh look, it's a rare case of snapshot Thursday! This week we're expanding your arsenal with a smashing new weapon, the Mace! Use this weapon's special smash attack while leaping from a high place and watch your enemies get knocked back. The longer you fall, the harder you hit – but make sure you time it right! Your fall damage is only negated if you land the blow. Craft this new weapon by combining a Breeze Rod with the Heavy Core, a new item you can find by unlocking Trial Chamber Vaults.

As usual, we invite you to share your thoughts about this new feature over at the feedback site: Let's talk about the Mace!

Alongside this hefty new mob swatter, we're also bringing you new chambers and variations to Trial Chambers, updated loot tables for Vaults, new Pottery Sherds, Armor Trims and Banner Patterns—as well as the usual slew of bug fixes and polish.

Happy mace-ing!

Experimental Features

Blocks

Heavy Core

Items

Breeze Rod

• An item dropped by the Breeze that can be crafted into 4 Wind Charges, or used with the Heavy Core to craft the Mace

Mace

• A new heavy weapon to smash your enemies!
• Leverage the weight of this new weapon to deal additional damage the farther you fall before hitting your target
  • Try it out by jumping down toward your target, and hit them before you hit the ground
  • Successfully striking a target in this way will negate any damage accumulated from the fall, similar to how a Wind Charge works
  • Other entities near the struck enemy will be knocked back by the immense force of the Mace
• Using a Mace will decrease its durability like any other weapon; repair it with Breeze Rods at an anvil

Technical Changes

• The Data Pack version is now 35
• The Resource Pack version is now 29

Data Pack Version 35

• Removed any entity sub-predicate
• Component-specific item predicate properties have been moved to separate field predicates
• Added slot name contents for single-slot entities like item frames and item displays
• Contents of item entity can now be accessed through contents slot name
• Added new loot functions

Predicates

Item sub-predicate

• Some fields from item predicate have been moved to a map in an optional field predicates
• The new field is similar to the components field on item stacks
• This was done to simplify addition for future predicates and to allow sub-predicates to more closely resemble names of components they match
• The following fields have been moved:
  • enchantments - field moved to sub-predicate minecraft:enchantments
  • stored_enchantments - field moved to sub-predicate minecraft:stored_enchantments
  • potions - field moved to sub-predicate minecraft:potion_contents
  • custom_data - field moved to sub-predicate minecraft:custom_data
• durability field has been expanded to minecraft:damage predicate:
  • This check now works for any item that has minecraft:damage component
  • An item that does not have a minecraft:damage component can never match
  • To check for unbreakable items, query value of minecraft:unbreakable component
  • Fields:
    • damage - optional bounds for value of minecraft:damage component
    • durability - optional bounds for durability (max damage minus value of minecraft:damage)
• Predicates minecraft:enchantments, minecraft:stored_enchantments, minecraft:potion_contents and minecraft:damage require matching component to exist on item
  • That means that, for example, matching for empty enchantment list will not pass on items without minecraft:damage component
  • Note: some components, like minecraft:enchantments have default values, so they will always match

Example:

Before:

"item": {
  "enchantments": [
    {
      "enchantment": "minecraft:silk_touch",
      "levels": {
        "min": 1
      }
    }
  ]
}

After:

"item": {
  "predicates": {
    "minecraft:enchantments": [
        {
          "enchantment": "minecraft:silk_touch",
          "levels": {
            "min": 1
          }
        }
      ]
  }
}
