Bee

We’re buzzing with excitement!

Can someone tell Cory to stop making bee puns now?

Bees are cute, fuzzy, neutral mobs
Don’t hurt them, they don’t want to hurt you
If a bee does sting you, it will leave its stinger in you and eventually die, dropping nothing :(
Bees love pretty flowers and spend their lives gathering pollen from them
After gathering pollen, bees fly back to their home nest
Bees help you by growing crops while carrying pollen back to the nest
Bees like sharing the location of their favorite flowers with other bees
If a bee doesn’t have a home nest, it will wander around until it finds one it can use
Bees don’t like the rain and they sleep at night. They will go back to the nest in these cases
Bees can be bred using flowers
If a bee can’t find nectar, after a while it will return home for a bit
Bees try to avoid water
Bees go inside if it’s raining at all in the world, not just where the bee is located
Bees will search up to 10 blocks away from itself in all directions to find a nest/hive to call home

Bee Nests / Beehives

In real life, bees dance in their nests to show other bees where flowers are!

Bee nests spawn naturally in flower forests, plains, and sunflower plains biomes
When a bee visits this block and completes its journey undisturbed, the level of honey increases
Max of 5 levels of honey
Level 5 is quite…sticky
Bees use nests and hives to share flower locations with other bees
Sometimes bees that already know about a flower will choose not to use this information
Beehives are crafted by players using honeycomb and wood planks
Use a silk touch tool to get the block with the bees stored inside
Bee nests will be destroyed unless you use silk touch
Use shears when at full honey to get honeycomb
Use a bottle when at full honey to get a honey bottle
Campfire smoke calms bees - place one underneath the nest/hive to keep them in chill mode
Redstone-friendly!
Bees like bee nests and beehives the same amount! They don’t play favorites :)
Bees only exit through the front of the nest/hive

Honey Block

Sticky. Very sticky!

Walking and jumping is limited
If you stand on a honey block that is pushed by a piston, you come along for the ride
Jump into a wall of honey blocks to slide down and slow your fall
Landing on a honey block cushions your fall somewhat
When a honey block is pushed or pulled by a piston, it sticks to adjacent blocks and tries to move them in the same direction (just like slime blocks do)
Honey blocks and slime blocks don’t stick to each other, because… um… because of special Minecraft chemistry
Mobs and animals dislike walking on honey blocks unless they really need to as it’s too sticky for their comfort
Honey blocks are crafted from four honey bottles

Honey Bottle

Organic, gluten-free, delicious locally-farmed honey!

Use an empty glass bottle on a hive or nest that is full of honey to get a bottle of honey!
Drink it!
???
Profit!
Oh yeah, also craft it into sugar!
Or craft four bottles into a honey block!
Drinking honey also cures poison

Honeycomb

Disclaimer: Cannot be used to comb your hair

Shear a full-honey hive or nest to obtain
Craft with wood planks to create a beehive

Honeycomb Block

BYOH - Build Your Own Honeycomb

Craft 2x2 Honeycomb to get a honeycomb block
Purely decorative!

Accessibility

Sneak and sprint inputs can now be switched between hold and toggle mode in the accessibility options
Descriptions under buttons on the create world screen are now narrated
Changed the button highlight to make it easier to distinguish which button is selected

Advancements

Added “Sticky Situation” for jumping into a honey block to break your fall.
Added “Bee Our Guest” for safely collecting honey from a beehive using a campfire.
Added “Total Beelocation” for moving a bee nest with 3 bees inside using silk touch.

Dispensers

Dispensers can now fill bottles with water and honey
Dispensers can now shear honey combs from bee nests and hives
Dispensers now eject empty bottles properly when not facing water

Iron Golems

Iron golems start cracking when badly damaged
Repair them with iron ingots!
Damage progress is based on ratio of current health to max health

Parity

Things from other editions of Minecraft have arrived to Java Edition!

Trying to sleep in a bed during daytime will now set the player’s spawn location to that bed
Setting the respawn point by using a bed now shows a message
Bells will now ring if powered with a redstone signal
The doInsomnia game rule can now be switched off to prevent phantoms from spawning during nighttime

Technical Changes

Item predicate in advancements now makes distinction between actual enchantments and stored enchantments (like ones stored in enchanted books)
Added General-purpose storage for data commands.
Added Spectate command.
Loot table predicates can now be defined in separate files and used for entity selectors and in execute if command
Extended advancement and loot table predicates
Extended schedule command to allow scheduling function multiple times

Advancements

Changes in item predicate:
- enchantments now only matches enchantments on item itself - it can no longer be used for enchanted books
- to match contents enchanted book, use stored_enchantments

Entity Predicate

player

Entity predicate now accepts player field, which checks player properties. Fails when entity is not player.

Fields:

level - range of allowed player levels
gamemode - same values as /gamemode command
stats - list of statistics to match. Entry fields: type (like minecraft:custom), stat (like minecraft:sneak_time) and value (int range)
recipes - map of recipe ids. Boolean value tells if it should or should not be known to player
advancements - map of advancement ids. If value is boolean, checks if advancement is done. If value is object, checks completion of critera

team

Entity predicate now accepts team field, which matches team name.

Location predicate

block and fluid

Predicate also accepts block and fluid sub-predicate. Available fields:

block/fluid - exact block/fluid id to match
tag - block/fluid tag to match
nbt - matcher for block entity NBT (only for blocks)
state - map of name-value properties. Value can be integer, boolean or string or object with optional min and max properties

light

Predicate now accepts light sub-predicate. Object has one integer range - light that matches visible light (max(sky-darkening,block)).

Chat components

Click action

Added Copy_to_clipboard action to clickEvent.

NBT chat component

Added Variant for NBT storage: {"nbt": <path>, "storage":"<resource id>"}. NBT storage can be manipulated with commands like /data merge storage <resource id> ..

Commands

data

Data commands can now use storage as target. This is general-purpose, key-value storage
- Storage is shared between all dimensions in level
- Data in storage persist between reloads

execute if predicate

New subcommand evaluates custom predicates (defined in predicates directory of datapack).

schedule

Added Syntax /schedule ... [append|replace] (/schedule ... defaults to replace).
Added Syntax /schedule clear <id> to remove existing schedules (returns number of removed schedules).

effect

The effect clear command now defaults to @s if no target argument is given.

Entity selectors

New selector parameter predicate allows to apply custom custom predicate (defined in predicates directory of datapack).

kill

The kill command now defaults to @s if no target argument is given.

Spectate

New command that makes a player in spectator mode spectate an entity. Syntax: spectate [target] [player]

Parameters:

player - The player that should spectate the target. Must be in spectator mode. If omitted, @s is used
target - The target to spectate. If omitted, makes the player stop spectating

Custom predicates

Condition part of loot tables can now be defined as separate data pack resource in predicates directory.

Loot tables

location_check

New parameters added:

offsetX, offsetY, offsetZ - optional offsets to location

time_check condition

New condition that checks day time.

Parameters

value - range of accepted values
period - if present, time will be modulo-divided by this value (for example, if set to 24000, value will operate on time of day)

New conditions

reference

Includes condition defined in predicates directory of datapack, selected with name parameter.

New functions

copy_state

Copies state properties from dropped block to BlockStateTag in dropped item.

Parameters

block - source of properties (block id)
properties - list of property names. All must be present on block

Modding

In an effort to help make modding the game easier, we have decided to publish our game obfuscation maps with all future releases of the game. This means that anyone who is interested may deobfuscate the game and find their way around the code without needing to spend a few months figuring out what’s what. It is our hope that mod authors and mod framework authors use these files to augment their updating processes that they have today. These mappings will always be available, instantly and immediately as part of every newly released version. This does not, however, change the existing restrictions on what you may or may not do with our game code or assets. The links to the obfuscation mappings are included as part of the version manifest json, and may be automatically pulled for any given version.

Prefixed to every obfuscation map is the following legal disclaimer:

Particle Performance

Vertically moving particles are performing better when they collide with blocks

Pistons

Bug fix

Blocks that can be manually placed on farmland can now also be pushed onto it by a piston without destroying the farmland

Resource Packs

The resource pack version is now 5
The game now tries to make out of date resource packs work as much as possible
Increased sizelimit for client downloading resource packs from 50MB to 100MB

State matching

Few advancements and loot table predicates that used block state properties (location, block_state_property, enter_block, placed_block) can now match ranges (by replacing single value with {"min": ..., "max": ...}).

Also, block type is now optional in those predicates - so for example it is not possible to match any crop with age property in certain range.

Textures

Changed texture map for all chests
Banner and shield patterns are now using alpha channel instead of brightness
Ender Dragon does not have separate texture for the bottom of the wing anymore
Enchanted item glint texture is now like it looks in the game

Command used to change the patterns

for f in *.png; do convert "$f" -alpha copy tmp.png && composite tmp.png -compose copy-opacity ../shield_base.png tmp2.png && convert tmp2.png -fill "rgba(0,1,0,1)" -draw "rectangle 0,0 1,63" -draw "rectangle 2,0 63,1" -draw "rectangle 2,22 64,64" -draw "rectangle 12,2 64,64" -fill none -draw "matte 0,0 floodfill" tmp3.png && mv tmp3.png "$f" && rm tmp.png tmp2.png; done
