Patch Notes

New Features

• Added variants of Wolves

Wolf Variants

• New Wolf variants have been added
• The variant is determined by the biome they spawn in
  • Pale Wolf - The familiar Wolf variant that now spawns in the Taiga biome, with a default pack size of 4
  • Woods Wolf - A variant that spawns in the Forest biome. This will be the dominant Wolf variant that you will be able to find in the Overworld, since the Forest biome is very common
  • Ashen Wolf - A variant that spawns in the Snowy Taiga biome
  • Black Wolf - A variant that spawns in the Old Growth Pine Taiga biome, in smaller packs of 2 to 4
  • Chestnut Wolf - A variant that spawns in the Old Growth Spruce Taiga biome, in smaller packs of 2 to 4
  • Rusty Wolf - A variant that spawns in a new location for wolves - the Sparse Jungle biome, in smaller packs of 2 to 4
  • Spotted Wolf - A variant that spawns in a new location for wolves - the Savanna Plateau biome, in larger packs of 4 to 8
  • Striped Wolf - A variant that spawns in a new location for wolves, the Wooded Badlands biome, in larger packs of 4 to 8
  • Snowy Wolf - A variant that spawns in the Grove biome. A rare type, that always walks alone
• Adjusted spawning conditions for Wolves, allowing them to spawn on Coarse Dirt and Podzol blocks

Changes

• Adjusted passive mobs spawning in Grove biome to only include Rabbits, Foxes and Wolves
• Button tooltips will no longer appear when hovering outside the containing element

Technical Changes

• The Data Pack version is now 34

Data Pack Version 34

• Recipe results can now specify component data
• Added new entity predicate field slots, for matching item slots
• Added slot names for ranges, like container.*
• Added execute if|unless items to check and count items
• Banner Patterns are now data-driven
• Changes to Item Stack Component formats
• Player Head blocks now store a custom_name tag, which will be copied to and from the item form when broken or placed
• The SkullOwner and ExtraType fields in Player Head blocks have been replaced with a profile field, with the same format as the item component
• For now, the count field on Item Stacks is always stored again, even if 1
  • If the field is missing in data, will still fall back to 1

Recipes

• Recipe types crafting_shaped, crafting_shapeless, stonecutting and smithing_transform now accept components for the result item stack
• The result field for recipe types smelting, blasting, smoking and campfire_cooking is now an item stack format without a count, which means you'll need to specify an object with an id field
  • This result now also accepts components data

Predicates Slots Entity Sub-Predicate

• New entity field slots allows to check single or multiple slots on any entity
• The field contains a map of slot names (same as ones used in item commands) to item predicate
• For slot ranges, only one slot needs to match for whole entry to pass

Example: { "condition": "minecraft:entity_properties", "entity": "this", "predicate": { "slots": { "container.*": { "items": "dirt" } } } } Slot Names

• Slot names (used in item commands and slots entity predicates) now include slot ranges
• Unless specified, existing commands can still only work on single slots
• New slot names:
  • container.* - contains container.0 to container.53
  • hotbar.* - contains hotbar.0 to hotbar.8
  • inventory.* - contains inventory.0 to inventory.26
  • enderchest.* - contains enderchest.0 to enderchest.26
  • villager.* - contains villager.0 to villager.7
  • horse.* - contains horse.0 to horse.14
  • weapon.* - contains weapon.mainhand and weapon.offhand
  • armor.* - contains armor.head, armor.chest, armor.legs, armor.feed, armor.body
  • player.cursor - item held by player on screen
    • Note: this information is not available in creative mode
  • player.crafting.0 - player.crafting.3, player.crafting.* - player's crafting slots
    • Note: this includes only player's inventory crafting slots. Crafting table (or any other slots on other screens) are not included

EXECUTE IF|UNLESS ITEMS

• execute if|unless items <source> <slots> <item_predicate> command can be used to count items
  • <source> is the same as one used in item command, i.e.
    • block <x> <y> <z>
    • entity <target> (selector can return multiple entities)
  • <slots> can accept single slot (like container.0) or a range (like container.*)
  • <item_predicate> is the same as item predicate in clear command
• If used alone, it will return total number of items in stacks that match predicates

Banner Patterns

• Banner Patterns will now be loaded into a dynamic registry from data packs (data/<namespace>/banner_pattern/<id>)
  • These entries have two fields:
    • asset_id (namespaced string) is used to resolve texture locations
      • e.g. custom:pattern resolves to assets/custom/textures/entity/banner/pattern.png, assets/custom/textures/entity/shield/pattern.png
    • translation_key (string) is a translation key prefix
      • e.g. block.minecraft.banner.custom.pattern resolves to block.minecraft.banner.custom.pattern.<dye color>

Item Stack Components

• The minecraft:profile component no longer requires the name field to be present
• Some additional Item Stack Components now support alternative, simple definitions:
  • minecraft:profile can be defined as string player name (e.g. profile="jeb_")
  • minecraft:dyed_color can be defined as an integer rgb color (e.g. dyed_color=16711680)
  • minecraft:attribute_modifiers can be defined as a direct list of modifiers (e.g. attribute_modifiers=[{type:'generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base'}])
  • minecraft:potion_contents can be defined as a single potion id (e.g. potion_contents="invisibility")
  • minecraft:enchantments and minecraft:stored_enchantments can be defined as an inline map of enchantment id to level (e.g. enchantments={sharpness:1})
  • These are only an alternative for defining the values, they will always be stored in their full formats
• All container blocks now use the minecraft:container component when in item form, not just Shulker Boxes
• The minecraft:lodestone_target component has been renamed to minecraft:lodestone_tracker
  • The pos and dimension fields have been moved into a target object
  • The target field is optional, and if not present, the compass will spin
• The maximum number of lore and fireworks entries has been raised to 256

Minecraft 1.21 Snapshot 24W10A: Patch Notes & How to Play

When players say that the winning mob affects more than just the mob being added, this is a perfect example of what they mean! Had Armadillos not won and added Wolf armor, none of these Wolf changes would likely have been added, at least in this update, anyway. Thank you, Armadillos! Until Next Time, BisectHosting =)
