Allay, the mob that nobody is really sure how to pronounce, is now entering the latest Minecraft: Java Edition snapshot. Along with our new shiny blue friend, we've added the ancient cities, which have seen some pretty drastic changes since the experimental snapshot a few weeks ago, so make sure you check them out.

Happy mining!

New Features in 22w13a

Added Allay mob
Added Ancient Cities

Allay

Allays will collect all the surrounding items that match the item they are holding
Allays will like a player who hands them an item and will bring the items they collect to their liked player
If the Allay hears a noteblock play, that noteblock becomes the Allay's favorite noteblock for 30 seconds. The Allay will stay near that noteblock for that duration and bring its collected items to the noteblock instead of to the player
Interacting with an Allay with an empty hand will remove the item the Allay is holding
Allays can be found in Pillager Outposts and Woodland Mansions

Ancient City

Wander the halls of these long-abandoned structures in the Deep Dark depths to uncover some relics long forgotten.

Ancient City structures spawn in the Deep Dark biome
In chests, guarded by sculk sensors and shriekers, you can find the new Swift Sneaking enchantment
You can also find a new mysterious block called Reinforced Deepslate here, which cannot be obtained in Survival
Mobs cannot spawn in Ancient Cities

Differences compared to the Experimental Deep Dark snapshot

Many adjustments have been made to Ancient Cities, with new and tweaked structures
Loot tables have been adjusted for Ancient Cities, including a separate loot table for the "ice box" structures

Changes in 22w13a

The recipes for minecart with chest/furnace/tnt/hopper are now shapeless
When broken each minecart variant drops itself as item, instead of splitting into two items (such as chest and minecart)
Only wool and wool carpets now block the sounds coming from noteblocks

Technical Changes in 22w13a

Added kill_mob_near_sculk_catalyst advancement trigger
Sculk shrieker block state changes
Renamed some game events

Advancements

New triggers

`kill_mob_near_sculk_catalyst`

Triggered when a player kills an entity next to Sculk Catalyst
Conditions:
- player - a player for which this trigger runs
- entity - a predicate for the entity that was killed
- killing_blow - a predicate for how the entity was killed

Sculk Shrieker

Added can_summon blockstate to the Sculk Shrieker that determines whether a Shrieker can summon a Warden or not
Shriekers placed via worldgen will have can_summon set to true
When a Shrieker is placed or generated via Sculk spread, can_summon is set to false

Game Events

Some game events have been renamed, with some of those changes to make them more gramatically consistent:

drinking_finish -> drink
entity_killed -> entity_die
entity_damaged -> entity_damage
elytra_free_fall -> elytra_glide
mob_interact -> entity_interact
ravager_roar -> entity_roar
wolf_shaking -> entity_shake

The following events have been collapsed into block_activate and block_deactivate:

block_press
block_unpress
block_switch
block_unswitch

Other miscellaneous changes to game events:

ring_bell has been removed and replaced with block_change
Both shulker_open and shulker_close have been removed in favour of using container_open and container_close
fishing_rod_cast and fishing_rod_reel_in have been renamed to item_interact_start and item_interact_finish
Added ignore_vibrations_on_occluding_block game event tag with subsequent logic
entity_interact should be dispatched more often when interacting with various mobs
