Changes

Items

Minecraft:Wolf armor

• Changed the crack textures.

Mobs

Minecraft:Bees and Minecraft:parrots

• Adjusted their flying behavior to keep them from overshooting their position when flying up and down.

Minecraft:Wolf

• When summoned using Minecraft:spawn eggs or Minecraft:commands, the variant selection now follows the natural spawning biome rules with the following extensions:
  • Rusty wolf is selected in Minecraft:jungles and Minecraft:bamboo jungles.
  • Spotted wolf is selected in Minecraft:savannas and Minecraft:windswept savannas.
  • Striped wolf is selected in Minecraft:badlands and Minecraft:eroded badlands.

Command format

Minecraft:Predicates

• Removed any entity sub-predicate.
• Added slot name contents for single-slot entities like Minecraft:item frames and Minecraft:item displays.
• Contents of item entity can now be accessed through contents slot name.
• Component-specific item predicate properties have been moved to separate field predicates.
  • 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 doesn't pass on items without minecraft:damage component
  • Note: some components, like minecraft:enchantments have default values, so they always match
