Minecraft Snapshot 25w10a

It's time for a new Minecraft snapshot! We've got some more under-the-hood updates including a tntExplodes game rule previously found in Bedrock edition, new features in SNBT syntax, and allowing all entities to store custom data. We also have some more bug fixes coming your way.

You can now also enjoy a new main menu background, happy mining!

Changes

• The Sheep wool texture has been tweaked to remove the stark line at the back
• Blocks that are broken by a Piston now play their breaking sound
• Updated the menu panorama for the first Game Drop of the year
• The textures of Test Blocks and Test Instance Blocks have been updated
• Cactus Flowers can now be placed on Farmland

Technical Changes

• The Data Pack version is now 70
• The Resource Pack version is now 54

Data Pack Version 70

• All entities can now store custom data
• Unified format and functionality of predicates for components on Entities and Block Entities
• New operations for SNBT
• Added new tntExplodes Game Rule
• Added #flowers item tag - corresponding item tag for the already existing #flowers block tag

Entity Data

• Custom data (previously present only on Marker) is now available on all entities
  • It's exposed as a minecraft:custom_data component, so it can be set by spawning items and matched by predicates
  • The component is currently stored in a field called data, which will be changed in the future when more proper storage for entity components is introduced
  • It's stored only if it's non-empty

Entity Predicates

• A new optional field has been added to entity predicates: predicates
  • Its functionality and format is identical to the field predicates on item predicates, but they operate on entity components
    • When present, predicates will match partial contents of entity components

Block Predicates

• New optional fields have been added to block predicates: components and predicates
• Their functionality and format are identical to the fields components and predicates on item predicates, but they operate on block entity components (when present)
  • When present, components will match exact contents of block entity components
  • When present, predicates will match partial contents of block entity components

SNBT Format

• To simplify input of data and macro use, SNBT now also supports following operations:
  • bool(arg) - converts argment to boolean
    • if argument is a boolean value, returns value directly
    • if argument is a number value, returns true if it is non-zero
  • uuid(str) - converts string representation of UUID to integer array
• Implicit infinite float values (like 1e1000) are now rejected

tntExplodes Game Rule

• When false, TNT will not explode and cannot be primed
• Default value: true

Resource Pack Version 54

• "Global" uniforms may now be defined in any shader, and the game will attempt to fill it
  • Currently, these are: ModelViewMat, ProjMat, TextureMat, ScreenSize, ColorModulator, Light0_Direction, Light1_Direction, GlintAlpha, FogStart, FogEnd, FogColor, FogShape, LineWidth, GameTime, ModelOffset
  • The type of the uniform must match what it would normally be, or it'll be undefined behavior
