Minecraft Snapshot 23w16a

In this weeks Snapshot we're bringing you tweaks to the Trail Ruins, new command functionality, a new advancement trigger, and more!

Happy mining!

Edit: We have published a fix for a crash issue in this Snapshot. If you are experiencing crashes, please try closing all instances of the game and restarting the Launcher.

Changes

• All Pottery Shards has been renamed to Pottery Sherds
• If a vibration is scheduled to be received by a Sculk Sensor or Sculk Shrieker, they will stay queued until all adjacent chunks are loaded and ticking
  • Prevents vibration resonance setups from breaking when unloading their chunks from a distance
• The game's application icon has been updated
  • This will be a Grass Block in release versions, and a Dirt Block in snapshot versions
• Added native support for ARM64 machine architecture on Windows
  • To try this out, you need to manually specify a native Java Executable in the launcher

Sniffer

• Sniffers can now be tempted by Torchflower seeds

Trail Ruins

• Reworked structures based on community feedback
• Added more structure variants
• Sand no longer generates within the structures
• Tweaked the amount of gravel and dirt
• Tweaked the amount of Suspicious Gravel
• Split the loot tables for the Suspicious Gravel within the structure. There is now a dedicated loot table for Rare loot items (e.g. Pottery Sherds, Smithing Templates), and a dedicated loot table for more common loot drops (e.g. Stained Glass Pane, Tools, Candles, etc.)
• Due to these changes you might see errors like Failed to get element ResourceKey[minecraft:worldgen/processor_list / minecraft:trail_ruins_suspicious_sand] in an old snapshot world. These are harmless, but existing Trail Ruin structures that was not previously fully loaded might be missing parts of the structure.

Technical Changes

• The data pack version is now 14, accounting for item display orientation changes
• Added a return command
• Added recipe_crafted advancement trigger

Commands

return

The return command can be used to control execution flow inside functions and change their return value. Effects:

• Remaining separate top-level commands in the currently executing function (if any) are skipped
• The result value of the function command that triggered the function is changed from the number of commands executed to value
• The result value of the return command is also value

Syntax:

return <value>

Parameters:

• value: An integer return value

Advancements

New triggers

recipe_crafted

• 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 will dictate the success of the trigger

Tags

• Added villager_plantable_seeds to represent which kind of seeds Villagers can farm
• Added maintains_farmland to represent which blocks will not cause farmland to be converted into dirt when placed on top of it

Display entity

Rendering changes

• 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)
