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

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)
