22w18a is the ninth snapshot for Java Edition 1.19, released on May 4, 2022,^[1] which adds the /place command, makes tweaks to allays, and fixes bugs.

/place

• A new command which replaces /placefeature and can place features, jigsaws and structures at a given location, with following syntaxes:
  • /place feature <feature> [<pos>]
    • Works like the removed /placefeature.
    • feature: The namespaced ID of a feature to try to place.
  • /place jigsaw <pool> <start> <depth> [<pos>]
    • Works as hitting the "generate" button inside the user interface of a jigsaw block: it generates a jigsaw structure starting in a certain template pool at a given jigsaw anchor, then does a given number of levels of expansion from there.
    • pool: The namespaced ID of a template pool to start generating.
    • start: The namespaced ID name of a jigsaw to use as the starting anchor.
    • depth: The maximum number of jigsaw connections to traverse during placement.
  • /place structure <structure> [<pos>]
    • Works by placing an entire structure just like it is done in world generation.
    • structure: The namespaced ID of a structure to try to generate.
    • pos: The position to use as the origin for the generation. (if omitted, ~ ~ ~ is used)

Chat

• Chat from the /say, /msg, /teammsg, and /me commands are now all also cryptographically signed.
• Servers can now define different chat style formats for clients, which can now be controlled by the server through the chat_type registry (found under the worldgen folder in the vanilla report).
  • These are synchronized to clients when they join the server.
  • The translation key or translation format can be defined, like chat.type.text or %s says: "%s".
    • Chat can be similarly optionally narrated with a custom translation key or format.
  • The entire message can have formatting applied, such as italics or a specific color (but currently not click or hover events).

Item modifier

• Added the item function set_instrument, to sets item tags needed for instrument items to a random value selected from a tag, with following parameter:
  • options: a tag reference specifying the instrument options to randomly pick from.

Tags

• Added following block tags:
  • #snow_layer_can_survive_on: honey_block, soul_sand, and mud.
  • #snow_layer_cannot_survive_on: ice, packed_ice, and barrier.
• Added following banner pattern tags (new type):
  • #no_item_required: square_bottom_left, square_bottom_right, square_top_left, square_top_right, stripe_bottom, stripe_top, stripe_left, stripe_right, stripe_center, stripe_middle, stripe_downright, stripe_downleft, small_stripes, cross, straight_cross, triangle_bottom, triangle_top, triangles_bottom, triangles_top, diagonal_left, diagonal_up_right, diagonal_up_left, diagonal_right, circle, rhombus, half_vertical, half_horizontal, half_vertical_right, half_horizontal_bottom, border, curly_border, gradient, gradient_up, and bricks.
    • Defines banner patterns which can be made on loom and do not need a pattern item.
  • #pattern_item/creeper: creeper
  • #pattern_item/flower: flower
  • #pattern_item/globe: globe
  • #pattern_item/mojang: mojang
  • #pattern_item/piglin: piglin
  • #pattern_item/skull: skull
• Added following instrument tags (new type):
  • #goat_horns: #regular_goat_horns and #screaming_goat_horns.
  • #regular_goat_horns: ponder_goat_horn, sing_goat_horn, seek_goat_horn, and feel_goat_horn.
  • #screaming_goat_horns: admire_goat_horn, call_goat_horn, yearn_goat_horn, and dream_goat_horn.

Sculk catalyst

• No longer spreads sculk upon death of mobs that do not drop experience (such as baby animals).

Allay

• Now follow their liked player even if they can't see them.
• Now only lose track of a player if they are more than 64 blocks away.

Advancements

• Changed the description for the "Sneak 100" advancement from "Sneak near a Sculk Sensor, Sculk Shrieker or Warden to prevent it from hearing you" to "Sneak near a Sculk Sensor or Warden to prevent it from detecting you".

Vibration

• Vibration listeners such as sculk sensors, sculk shriekers and wardens now listen to the closest vibration instead of the first vibration in the tick.

/placefeature

• Merged into the new /place command.

Data pack

• The built-in vanilla pack, the report generated by the game, and the vanilla world generation reference pack now store their object keys sorted alphabetically (with the exception of type fields and parent fields, which get listed first).
  • This makes diffing the files easier after changes, and avoids false positive changes from fields moving around.

Item modifier

• Removed the item function set_goat_horn_sound.

Particles

• Changed the texture of the sonic boom particle.

Tags

• Removed flap game event from the #vibrations and #warden_can_listen game event tag.

General

• The bundled Java runtime has been upgraded to 17.0.3.
