Gameplay

Bartering

Splash Potion

  • Splash potions distance to affected entities now depends on the closest distance between the entity hitbox and the splash potion hitbox where it landed.
    • If an entity is hit directly by the splash potion, it will receive the full effect of the potion.
    • If the entities are grouped together, they will receive the same effect strength.

General

Data pack

Entity data

  • Added home_pos and home_radius fields to all mobs.
    • Mobs with set home position will limit their pathfinding to stay within the indicated area.
    • Some mobs, like bats, slimes, magma cubes, phantoms and ender dragons may ignore it.
    • Interacting with leashes or riding may change the home position of the mob.

Fonts

  • uniform font has been updated to use Unifont 16.0.03.
  • Added previously omitted Unifont glyphs for Private Use Areas.
    • Those glyphs are loaded as a separate sub-font minecraft:include/unifont_pua and are not included in any normally used font.
    • Characters in those areas are managed by Under-CSUR (Under-ConScript Unicode Registry), which adds various scripts not present in official Unicode set, like Tengwar or Sitelen Pona.
  • Unihex Font Provider
    • Field size_overrides is now optional (defaults to empty list).

Resource pack

  • The version is now 59.
  • All JSON files (in worlds, packs, configuration, etc.) are now parsed in strict mode.
  • The hud/locator_bar_arrow_up and hud/locator_bar_arrow_down sprites are now animated with a standard animation definition in the corresponding .mcmeta files.

Tags

  • Updated the #followable_friendly_mobs entity tag to include the happy ghast.
