Minecraft Snapshot 18w43c

The first snapshot for 1.14 "Village & Pillage" is here, and oh boy, it's a big one! With new items, new blocks, new mobs, new blocks, new enchantments, new blocks, new mechanics, even more new blocks, new commands, and not to forget all the new blocks - we're pretty confident there's something for everyone in this snapshot!

Best of all, this is just the first one! We have so many things coming to future snapshots, most of which you guys don't even know about yet! Hurray!

However, as always the first snapshot is always the riskiest. We're rewriting big chunks of the game with hopes of focusing on performance soon, so stability might be a little wonky at first. Please backup before opening your favourite worlds!

We've got a huge changelog for this snapshot, which we're really proud of. If you scroll all the way to the bottom you'll find instructions on how to play (spoiler: start up your launcher and enable snapshots!)

Now, without further ado, we present to you... a changelog!

• Fun, challenging advancements!
• New loading mechanics!
• Unique load animation!

Enchantments

• Choose between the following three enchantments for your crossbow:

Multishot (I)

• Ever wanted to shoot more than one arrow at once? Look no further! With Multishot, your crossbow splits your arrow into 3, shooting the usual arrow straight ahead and two more at angles off to the sides!
• Cannot be combined with Piercing

Piercing (I, II, III, IV)

• With this pointy enchantment, arrows shot from your crossbow can travel through mobs, hitting more than one per shot
• The number of mobs that can be damaged by a single arrow is equal to the level of this enchantment + 1
• Cannot be combined with Multishot

Quick Charge (I, II, III)

• Each level of quick charge decreases the amount of time it takes to fully charge your crossbow by .25 seconds

Loading Mechanics

• To charge the crossbow, hold down the "Use" button
• Once the crossbow string has been pulled all the way back, let go
• Boom! Your crossbow is now loaded and ready to shoot with a single click of the "Use" button

New Textures

The extraordinary Minecraft Texture Update has been available on minecraft.net for quite a while and now it’s finally available by default in the game

• We’re renovating the old textures of Minecraft and polishing them up for a new beginning.
• We're still interested in feedback
• Playing on Bedrock ? Don't worry! These textures will come to the Marketplace in a near future for you to try out!

Panda

We heed the call!

• Pandas come in different variants and personalities! There is a rumour about a brown panda...
• Pandas love bamboo... they kinda like cake as well
• Pandas can be bred, and the variants are inherited by a special panda inheritance system
• Pandas spawn natuarlly in the new bamboo forest biome
• Pandas drop bamboo when killed
• Most importantly: pandas are cute and terribly silly!
• The babies are, in general, even more silly than their parents.

Advancements

• Entity type predicates now accept tags (#baz)

Damage source predicate

Damage source predicate now has option: is_lightning.

Entity flags predicate

Entity predicate now accepts flags field. Available tests: is_on_fire, is_sneaking, is_sprinting, is_swimming, is_baby.

Chat components

NBT chat component

• Block variant {"nbt": <path>, "block":{"x":<x> "y":<x>, "z":<z>}}
• Entity variant {"nbt": <path>, "entity":<selector>}
• Additionaly, if field interpret is present and set to true, contents of selected tags will be interpreted as chat components

Commands

• type field in @ selectors now accepts entity type tags (type=#foo and type=!#bar)
• Item frame contents can now be modified with /replaceitem

DATA

• data modify <block or entity> <path> <operation> <source>
  • Apply operation to selected fields
  • Basic operation: set - replaces value
  • List operations: insert before index |insert after index|prepend|append
  • Object operations: merge
  • Sources:
    • from <block or entity> <path> - copies value from existing tag
    • value <nbt> - uses NBT literal

drop

General syntax: drop <target> <source>

Sources

- `award` - uses advancement award context
- `fish` - uses fishing context
- `loot` - uses loot chest context
- `kill` - simulates entity drops
- `mine` - simulates block drops

Targets

- `world` - drops in world
- `player` - puts in player inventory (as if picked)
- `entity` - sets entity slots (same as `replaceitem`)
- `block` - puts (`distribute`, as if shift-clicked) or replaces/mer

EXECUTE

• execute if data <block or entity> <path> (and execute unless)
  • when used as command, return count of matched elements
  • when used as part of command, continues on non-zero(if) or zero(unless) count

SCHEDULE

Schedules function or tag to run in <time> gametime ticks. Returns trigger time. Any tag or function can be scheduled only once. Calling this command for already scheduled function or tag will replace older record.

NBT PATHS

• Can now return multiple values. When used as target, modification will be applied to every element
• When setting location and no elements are found, new matching element will be created:
  • For example writing to Items[{Slot:10b}] will either found element in Items for slot 10 or create new one
• Add [{k1=v1,k2=v2}] to match objects in list that have matching fields
• Add {k1=v1,k2=v2} to match objects (selects 0 or 1 elements, mostly as safeguard against mismatched entries)
• Allow negative indices in [index] to select element from end (i.e. [-1] is last element, [-2] second to last, etc)
• Add [] to select all elements from list

LIGHT ENGINE

We are de-lighted to have a new light engine!

• Moved light storage from chunks to a separate structure
• Moved light calculation from all over the code to a self-contained place
• Moved light computation off the main thread (on the server)

LOOT TABLES

• Block drops are now controlled by loot tables (stored in loot_tables/blocks/)
• Tables and pools accept functions
• Added new loot table entry types: dynamic, tag, alternatives, sequence, group
• Added new loot table functions: apply_bonus, explosion_decay, copy_name, limit_count, set_contents, set_loot_table
• Added new loot table conditions: entity_present, survives_explosion, block_state_property, table_bonus, match_tool, tool_enchantment and two special modifiers: inverted and alternative
• Integer values can now specify random number generator (available types: constant, uniform, binomial). If omitted, defaults to uniform
• Loot tables have optional type, used to validate function usage (available types: empty, chest, fishing, entity, advancement_reward, block). Using function that references data not available in given context (for example, block state in fishing table) will cause warning
• New entity parameter in predicates: direct_killer_entity - allows access to projectiles etc.
