Gameplay

Creative inventory

Items and blocks in the creative inventory have been reorganized, with the goal of making overall sorting more intuitive:
- Trial chamber items:
  - Trial keys were moved to be next to ominous trial keys.
  - Ominous bottles were moved next to the existing potions and were made into its own "Ominous Bottle" group.
- Stone group in the "Nature" tab:
  - Stone was moved into the "Stone" group.
  - Stone is now the front block of the "Stone" group.
  - Basalt and smooth basalt were moved into the "Stone" group.
  - Tuff and polished tuff were moved into the "Stone" group.
- "Decorative Stone" in the "Construction" tab:
  - Smooth stone was moved into "Decorative Stone".
  - Tuff bricks, chiseled tuff, and chiseled tuff bricks were moved from the "Nature" category to "Decorative Stone" in the "Construction" category.
  - Prismarine bricks were moved from the "Decorative Stone" group, now they are next to prismarine and dark prismarine.
- Copper family:
  - Reordered raw iron, raw copper, raw gold to raw copper, raw iron, raw gold.
  - The copper, iron, and gold blocks were moved to match the raw versions ordering.
  - The copper doors were moved to all the other doors.
  - The copper trapdoors were moved to the group with all the other trapdoors.
  - Copper blocks and copper grates are now sorted by block type then by oxidation level, instead of oxidation level then block type.
- Tuff family:
  - Tuff stairs, tuff slabs, tuff walls, and their polished versions were moved from the "Nature" tab to the "Construction" tab into their respective groups.
- Other blocks
  - Bricks are now placed before the "Slabs" group.
    - This change only affects bricks made from clay and not all the brick blocks.
  - Chiseled nether bricks and cracked nether bricks were moved next to the nether bricks block and red nether bricks.
  - Quartz bricks placed next to the other quartz blocks.
  - Rooted dirt is now next to the other dirt blocks.
  - Many dirt blocks and grass variants were shuffled around for a greater parity with Java Edition.
  - Gravel is now ordered after the "Stone" group and is next to sand and red sand.
  - Clay was moved from the "Construction" category to the "Nature" category, placed next to the mud block.

Technical

Behavior Packs

Updated references to old block names in remaining behavior pack recipe files.

Blocks

Added content warning when carried_textures or blockshape are incorrectly written in blocks.json.

Components

Renamed the minecraft:lookat component to minecraft:looked_at to better reflect its functionality:
- Its look_event field was also renamed to looked_at_event.
- Its look_cooldown field was also renamed to looked_at_cooldown.
Expanded the minecraft:looked_at component functionality with the addition of six new [Beta] fields:
- find_players_only restricts the search for entities looking at the owner entity to players only, ensuring that the closest player satisfying the specified filters is selected.
- look_at_locations defines the parts of the owner entity that are targeted for being looked at:
  - For these parts, a line-of-sight check is performed to ensure no blocks obstruct the view.
  - Supported values are head, body, and feet.
- not_looked_at_event specifies the event to trigger when no suitable entity is looking at the owner entity.
- field_of_view defines the width of the field of view, in degrees, for entities looking at the owner entity:
  - If scale_fov_by_distance is set to true, this value corresponds to the field of view at a distance of one block between the entities.
- scale_fov_by_distance determines if the field of view narrows as the distance between the owner entity and the entity looking at it increases.
  - This ensures that the width of the view cone at the owner entity position remains relatively constant, regardless of distance.
- line_of_sight_obstruction_type defines which block shape is considered when checking for line-of-sight obstructions.
  - Supported values are outline, collision, and collision_for_camera.
- Moreover, et_target now supports three different values:
  - never, looking entities are never set as targets, but events are emitted.
  - once_and_stop_scanning, the first detected looking entity is set as target, but scanning and event emission is suspended if and until the owner entity has a target.
  - [Beta] once_and_keep_scanning, the first detected looking entity is set as target, but scanning and event emission continues.
- All these fields are planned to be taken out of [Beta] and fully released at a later date.

Entity Event Responses

Added the reset_target entity event response, which allows an entity to reset its target.

Feature

Using unsupported feature placement in pregeneration_pass will now throw a content error instead of crash.

Graphical

Add new the_end.client_biome.json as the first new type of file to contain per-biome rendering and audio settings in resource packs.

Items

The minecraft:item object is parsed with a strict loader from 1.21.40:
- Numbers and booleans are no longer interchangeable in the JSON input.
- Floating point numbers are no longer accepted where an integer is expected.

Experimental

These additions and changes are accessible by enabling the "Beta APIs", and "Upcoming Creator Features" experimental toggles.
