Gameplay

General

Minecraft:Data pack

• The Minecraft:pack format version is now 43.
• Registry decorated_pot_patterns has been renamed to decorated_pot_pattern.
• Renamed directories; each directory that used the plural name of its element now matches registry name:

Old name	New name
tags/items	tags/item
tags/blocks	tags/block
tags/entity_types	tags/entity_type
tags/fluids	tags/fluid
tags/game_events	tags/game_event

Minecraft:Data component format

• The custom_data component can now be specified as an SNBT string to preserve type information in JSON.
  • This is the same as is used in the set_custom_data loot function and custom_data predicate.
• The food item component has new fields:
  • using_converts_to: item with components (optional).
    • Once consumed, the food item is replaced with the specified item.
    • e.g. food={nutrition:1,saturation:0,using_converts_to:{id:"poisonous_potato",components:{"minecraft:custom_name":'"Wait what?"'}}}.

Minecraft:Entity format

• Removed power tag and replaced with acceleration_power tag with a number value that control the projectile's acceleration (and maximum speed).
  • This change affects the following projectiles; dragon_fireball, large_fireball, small_fireball, fireball, breeze_wind_charge, wind_charge, wither_skull.

Minecraft:Custom structure

• New tag dimension_padding for structures.
  • Ensures that a structure is not generating through the edges of a dimension by adding vertical padding to its bounding box.
  • Default is 0.
  • Trial chambers have a padding of 10 since they are generated deep underground and would sometimes intersect with bedrock layer.

Entity effect types

• Adds optional field trigger_game_event for effect types replace_block, replace_disc and set_block_properties.
  • Game event ID for a game event to trigger when a block has been replaced.

Minecraft:Tags

• Added fire_aspect_lightable to each block that should be possible to light by Template:Control it with a tool that has Minecraft:Fire Aspect.

Damage type predicate

• New option: is_direct - optional boolean.
  • When present, true requires the damage to be direct and false requires the damage to be indirect.
  • Damage is direct when its direct and source entities are the same.

Performance

• When reading an already generated chunk from disk, surrounding chunks are no longer unnecessarily loaded, reducing memory and CPU overhead.
