23w16a is the fourth snapshot for Java Edition 1.20, released on April 20, 2023,^[1] which adds a new command and fixes bugs.

/return

• A new command that can be used to control execution flow inside functions and change their return value. Effects:
  • Skip remaining separate top-level commands in the currently executing function (if any).
  • The result value of the function command that triggered the execution is changed from the number of commands executed to the value.
  • The result value of the return command is also the value.
• Syntax: /return <value>
  • value: An integer return value.

Advancements

• Added recipe_crafted advancement trigger; triggered when crafting a recipe.
  • Conditions:
    • recipe_id: The resource location of the recipe crafted.
    • ingredients: An array of predicates for the item stacks used in the recipe.
      • A single item stack can only be used to fulfill one predicate.
      • Each predicate needs to be fulfilled to trigger the advancement. This allows for seperation between recipes that have same identifier but use different ingredients.
      • This field is optional. When not provided, or left empty, only the recipe_id dictates the success of the trigger.

Splashes

• Added splashes:
  • This sand is sus
  • Remember to brush your... ...teeth
  • Has working bookshelves!
  • Sniff sniff...
  • Place hanging sign here

Tags

• Added block tags:
  • #maintains_farmland: contains pumpkin_stem, pumpkin, attached_pumpkin_stem, melon_stem, melon, attached_melon_stem, beetroots, carrots, potatoes, torchflower_crop, torchflower, pitcher_crop, and wheat
    • Blocks that don't cause farmland to be converted into dirt when placed on top of it.
• Added item tags:
  • #villager_plantable_seeds: contains wheat_seeds, potato, carrot, beetroot_seeds, torchflower_seeds, and pitcher_pod.
    • Seeds that villagers use to farm.
• Added block and item tags:
  • #stone_buttons: contains stone_button and polished_blackstone_button.

👁 Image
👁 Image
Sculk Sensor and sculk Shrieker

• If a vibration is scheduled to be received by a sculk sensor or sculk shrieker, they stay queued until all adjacent chunks are loaded and ticking.

Display

• item_display items have been rotated 180 degrees around Y axis to better match transformation applied when rendering items on armor stand head and in item frames.
  • For reference, order of transformations applied to model (starting from innermost) is item_transform, rotate Y 180, transformation field, entity orientation (billboard option + Rotation field + Pos field).

👁 Image

• Reworked and added more variants.
• No longer generates with sand and suspicious sand.
• Tweaked the amount of gravel, dirt, and suspicious gravel.
