  • gameplay/hero_of_the_village/baby_gift - used if the Villager is a baby.

Changes

Items

Ender Pearl

• Thrown Ender Pearls now load and tick chunks around it in a 3x3 chunk area.
  • Ender Pearls now ensure that the chunk they are in or travel into is always loaded and ticking.
  • An Ender Pearl creates a ticket for chunk loading any time it moves into a new chunk, and also periodically every 10 seconds.
  • They also load chunks when crossing to a new dimension, so that they can always continue to travel.
  • This ensures that Ender Pearls can always land, and makes cross dimensional Ender Pearl travelling more predictable.
  • Ender Pearls now unload when a player logs out, and reappear whenever that player logs back in, similar to how mounts currently behave.

General

Advancements

• The trigger minecraft:killed_by_crossbow was renamed to minecraft:killed_by_arrow.
  • Will now trigger whenever an Arrow kills an entity, not just when fired from a crossbow.
  • Has a new optional Item Predicate field, fired_from_weapon.
    • Can be used to match the item used to shoot the arrow.

Data component format

• minecraft:fire_resistant was renamed to minecraft:damage_resistant
  • Has a new field: types, hash-prefixed damage type tag.
    • Items with this component, when in entity form, will be resistant to the damage types included in the tag.
    • This component also affects whether the equipped item will be damaged when the wearer is hurt by a given damage type.

• minecraft:item_name
  • Name provided by this component always has the lowest priority.
  • That means it will be overridden by components like minecraft:potion_contents.

• minecraft:potion_contents
  • Added optional string field custom_name.
    • When present, it will be used to generate containing stack name.
    • For example, if value is foo and item is minecraft:lingering_potion, the name of item will be translation of item.minecraft.lingering_potion.effect.foo.

• minecraft:equippable
  • Added the following fields.
    • swappable: boolean (default: true), whether the item can be equipped into the relevant slot by right-clicking.
    • damage_on_hurt: boolean (default: true), whether this item will be damaged when the wearing entity is damaged.

Data pack

• The pack format version is now 53.

Loot tables

• The tool value (used for functions like match_tool) is now available for some additional loot table types.
  • archaeology - used brush.
  • vault - inserted key (not available when displaying items).
  • shearing - shears.

Resource pack

• The version is now 38.
  • The appearance of a highlighted slot can now be customized by replacing sprites (this supports the use of animated textures):
    • container/slot_highlight_front: The sprite to render in front of highlighted slots.
    • container/slot_highlight_back: The sprite to render behind highlighted slots.
  • Likewise, the appearance of a highlighted item within the Bundle can be customized with the following sprites:
