Changes

General

UI

Added model to handle Not Enough Disc Space error in Edit World screen, Resource Packs tab.
Stopped main menu background rotation when entering new player flow
Stopped main menu background rotation and logo text movement when the "screen animations" option is disabled.

Technical

Biomes

Moved Vanilla biome JSON files from an internal folder to the appropriate Vanilla behavior packs.

Components

The minecraft:rideable component now has three new additional fields:
- dismount_mode defines where riders are placed when dismounting the entity:
  - default, riders are placed on a valid ground position around the entity, or at the center of the entity's collision box if none is found.
  - on_top_center, riders are placed at the center of the top of the entity's collision box.
- on_rider_enter_event, defines the event to execute on the owner entity when an entity starts riding it.
- on_rider_exit_event, defines the event to execute on the owner entity when an entity stops riding it.

General

Updated the client side biome component minecraft:water_appearance field surface_color to be optional. Added a content error that fires if the component is empty.

Goals

minecraft:behavior.float_wander has been updated with new fields:
- navigate_around_surface: enables the usage of a new algorithm to find random positions to navigate to. The new algorithm aims to find random positions in the vicinity of solid (i.e. non-air and non-liquid) blocks, and if that fails will fall back to finding a random position in the vicinity of the current dimension's surface level.
- additional_collision_buffer: makes sure there are no blocks present in an inflated area around the target position.
- allow_navigating_through_liquids: allow the mob to have target positions inside liquids.
- surface_xz_dist: the distance in the horizontal directions to look for nearby surfaces. Only valid when navigate_around_surface is true.
- surface_y_dist: the distance in the vertical directions to look for nearby surfaces. Only valid when navigate_around_surface is true.
minecraft:behavior.follow_mob has been updated with the following new fields:
- use_home_position_restriction: If true, the mob will respect the minecraft:home component's restriction_radius field when choosing a target to follow. If false, it will choose target position without considering home restrictions.
- preferred_actor_type: The type of actor to prefer following. If left unspecified, a random actor among those in range will be chosen.
- filters: If non-empty, provides criteria for filtering which nearby Mobs can be followed. If empty default criteria will be used, which will exclude players, squid variants, Fish variants, tadpoles, dolphins, and mobs of the same type as the owner of the goal.

Molang

query.graphics_mode_is_any no longer requires the Upcoming Creator Features experiment.

Network Protocol

Added ActorFlags::DOES_SERVER_AUTH_ONLY_DISMOUNT.

Experimental

These additions and changes are accessible by enabling the "Beta APIs" and "Locator Bar" experimental toggles.

Additions

Gameplay

Player Locator Bar

The Player Locator Bar is a new UI element on the player HUD that displays the direction of other players in the world.
- When the player locator bar experiment is enabled and there are multiple players in a world, the player locator bar will appear on-screen for each player, replacing the experience bar. The player level number will still be visible as before above the player locator bar.
- The Player Locator Bar will display colored indicators when the camera is facing within 120 degrees towards another player. If another player is 30 degrees above or below the camera's viewport (the screen) an up or down arrow will be displayed.
- Crouching will hide the player, preventing their indicator from appearing on the player locator bar of other players.
- Players in spectator mode are not visible on the player locator bar.
- A mob head or a carved pumpkin will similarly hide players from the player locator bar when worn in the head slot.
Using a potion of invisibility will also hide players from the player locator bar.
