Changes

Non-mob entities

Projectiles

  • Projectiles now have a target tolerance margin that changes over time.
    • All projectiles start with no margin for the first two ticks of their flight.
    • After that, the target margin will expand by 0.05 blocks per tick until it reaches the previous fixed 0.3 blocks margin.
    • This allows for better precision close to the shooting player or entity, while still allowing for some collision leeway when the projectile is further away.

General

Attributes

  • The scale attribute for the happy ghast now has a limit of 1.0.

Data pack

  • The pack format version is now 76.
  • --quickPlaySingleplayer command line argument can now be used without an identifier to launch into the last played world.

Entity format

  • tnt
    • The entity that primed the TNT is now stored in an optional owner field (UUID of Living entity).
  • vex
    • The owner of a vex is now stored in an optional owner field (UUID of Mob).

Resource pack

  • The version is now 60.
  • Panorama textures must now all be the same size, and square.

Shaders

  • Shader fog
    • The fog is now split into environmental and render-distance-based.
    • Previously both those concepts were mixed in the same uniforms.
    • Environmental fog is supposed to represent the "fogginess" of the environment the player is in: lava, water, and now also atmosphere.
    • Render distance fog is supposed to obscure the border of visible terrain.
    • Environmental fog uses spherical distance to determine its intensity, render distance fog uses cylindrical distance.
    • The resulting fog value for any given vertex is the maximum of both.
  • Fog uniform block
    • FogStart was renamed to FogRenderDistanceStart and now represents the render distance fog start.
    • FogEnd was renamed to FogRenderDistanceEnd and now represents the render distance fog end.
    • FogEnvironmentalStart is new and represents the start of environment-based fog.
    • FogEnvironmentalEnd is new and represents the end of environment-based fog.
    • FogShape was removed. Render distance fog is now cylindrical and environmental for is spherical.

Sounds

  • The sound event block.dried_ghast.hit has been removed.
