Alongside all the Minecraft 1.21 content released so far, Minecraft 1.21 Snapshot 24W11A adds a brand-new melee weapon to the game! The Mace and it is not as simple as it may appear. Crafted with the newly added Breeze Rods, this weapon grows stronger the longer one falls through the air.

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 } } ] } } Loot Functions set_fireworks New function for setting the details of the minecraft:fireworks component.
