Minecraft Java Edition - Snapshot 21W05A

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.

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 till 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
