Minecraft Snapshot 21w05a

A Minecraft Java Snapshot

In today's snapshot, we're adding a few new blocks that you, later on, will see in the lush caves! They're perhaps not as lush as Jens' hair, but close enough.

Update: We've now released 21w05b to fix a couple of bugs.

Fixed bugs in 21w05b

  • MC-203813 - Copper blocks are named inconsistently
  • MC-213788 - The game can randomly freeze
  • MC-213802 - Copper is not upgraded correctly from pre-21w05a worlds

New Features in 21w05a

  • Azalea bushes as well as flowering azaela bushes!
  • Added cave vines and glow berries!
  • Added drip leaves!
  • Added decorative blocks for the upcoming lush caves: hanging roots and rooted dirt!
  • Added moss!
  • Added spore blossom!

Cave vines and glow berries

  • Cave vines grow down from the ceiling, like weeping vines
  • When they grow they have a chance of producing glow berries
  • Glow berries are a natural light source as well as a food source
  • Foxes eat glow berries
  • Use glow berries to plant new cave vines
  • Bonemealing a cave vine will create glow berries

Dripleaf

  • Small dripleaf needs moisture, so it grows on clay or underwater
  • Small dripleaf grow into big dripleaf when bonemealed
  • Big dripleaf grows taller when bonemealed
  • If you stand on a big dripleaf, it will tilt after a while and you will fall off
  • You can crouch or jump to prevent a big dripleaf from tilting
  • A tilted big drip leaf will tilt up again after a while
  • The big dripleaf will break when hit by a projectile
  • The wandering trader will sometimes sell small dripleaf plants

Moss

  • Two new decorative blocks: moss block and moss carpet
  • Moss carpet can be crafted from moss blocks

Spore blossom

  • A beautiful large flower placed on ceilings
  • Particles drip from it

Changes in 21w05a

  • The stonecutter can be used to craft the different copper block variants
  • The stages of copper oxidization are now called “Copper Block”, “Exposed Copper Block”, “Weathered Copper Block” and “Oxidized Copper Block” in sequence of least to most oxidized
  • Drowned now have a chance of dropping a copper ingot, they no longer drop gold ingots
  • Added new sculk sensor events
  • Changes to powder snow

Sculk Sensor Changes

Added the following game events that the Sculk Sensor reacts to, along with corresponding frequency value:

Vibration Types Frequency Value
Minecart Moving, Ring Bell, Block Change 6
Drinking Finish, Prime Fuse 7
Mob Interact 8
Equip, Shear, Ravager Roar 9
Entity Place 12
Entity Killed 13
Shulker Close 14
Shulker Open 15
  • Block Change is for when player or dispenser action has changed a block. Example: cake slice being eaten
  • Mob Interact is for specific mob interaction events that cause vibrations
  • Prime Fuse is for both TNT and Creepers

Powder Snow changes

  • Flaming arrows now get extinguished when they collide with powder snow
  • Skeletons now convert to strays when frozen
  • Powder snow is now pushable by pistons and sticky pistons
  • Foxes can now walk on top of powder snow without falling in

Technical Changes in 21w05a

  • Improved performance when using many overrides on an item model
  • Copper oxidization is now a random tick effect and thus affected by the randomTickSpeed game rule
