Java Edition: Snapshot 21W05A/B

 

As someone who isn't extremely creative with house designs, I've always found myself living in caves for convenience and safety.  Today and yesterday's snapshots are starting to introduce features that will be coming with the new Lush Cave biome, and I have to say, the blocks are extremely pretty.  What was your favorite thing about this snapshot?  What are you waiting to see from the announcements?

NEW FEATURES IN 21W05A

  • Azalea bushes as well as flowering azalea 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 the 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
