/execute

• Added new slots condition sub-command.
  • Counts the number of slots from the slot source that are present on the targeted block or entity.
  • The slot source will be evaluated with the minecraft:command_slot_source loot type.
  • Syntax:
    • /execute execute if unless slots block <pos> <slot source>
    • /execute execute if unless slots entity <targets> <slot source>
• The items condition sub-command now takes a slot source as argument instead of a slot.
  • The slot source will be evaluated with the minecraft:command_slot_source loot type.

  • It will be evaluated with the minecraft:command_slot_source loot type.
  • Can be a slot source in either inline or reference form.
  • Can be a slot source targeting multiple slots.
  • The replace sub-command has new semantics:
    • One by one in the order they are provided by the slot source, the contents of each destination slot are replaced with the corresponding source item.
    • When there are more destination slots than there are source items, the remaining slots are ignored.
      • Example: replace [12345] with (ABC) -> [ABC45]
    • When there are fewer destination slots than there are source items, the remaining items are ignored.
      • Example: replace [123] with (ABCDE) -> [ABC]
  • String notation slot ranges in the form <slot_type> or <slot_type>.<slot_number> are still permitted.
    • Can be a single slot, such as armor.chest
    • Can be multiple slots, such as container.*
    • Acts as shorthand for a minecraft:slot_range slot source using that slot range.
      • Example: hotbar.4 is the same as {type:"minecraft:slot_range",slots:"hotbar.4"}
• The entity argument in the from entity item source can now be a selector targeting multiple entities.
  • When more than a single entity is targeted, the slots sourced from each are concatenated.
• Added new fill and override sub-commands, each with syntax identical to /item replace.
  • /item fill
    • Fills each destination slot with a source item.
    • When there are more destination slots than there are source items, the items repeat until every slot is filled.
      • Example: fill [12345] with (ABC) -> [ABCAB]
  • /item override
    • Overrides the contents of each destination slot with the corresponding source item.
    • When there are more destination slots than there are source items, the remaining slots are cleared.
      • Example: override [12345] with (ABC) -> [ABC__] (where _ represents an empty slot).

/team

• The result of /team join and /team leave subcommands now reflects the exact count of entities that have joined or left (i.e. excluding entities for which teams have not changed).

/tellraw

• The nbt component in a raw chat message will only be resolved up to 64k times.

/tick

• The following subcommands will now signal an error instead of just printing an error message and returning 0:

  • /tick sprint stop

  • A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_rule/<id>.json.
  • Elements in this registry define a pipeline for selecting what base block to place in the world at a given position.
  • The format is identical to that which was formerly written in the surface_rule field within noise settings files, with the following extensions:
    • Material rules can now be specified either inline (as previously), or as an ID reference to an element in the worldgen/material_rule registry.
    • Material conditions can also now be specified as an ID reference to an element in the worldgen/material_condition registry.

• Material Condition Registry
  • A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_condition/<id>.json.
  • Elements in this registry define a condition that can be referenced within a Material Rule pipeline (e.g. testing biome or surface depth).
  • The format is identical to that which was formerly written within the condition Material Rule type, with the following extension:
    • Material Conditions can also now be specified as an ID reference to an element in the worldgen/material_condition registry.

• Structure Placements
  • Added minecraft:dimension_origin
  • New structure placement that places a single instance of the structure at the dimension origin.
    • The dimension origin is defined as the spawn_target for noise settings based dimensions, otherwise Chunk (0, 0).
  • No additional fields.

• Rule Tests
  • These are the predicates used by ore Features (targets[].target), and rule Structure Processors (rules[].input_predicate and rules[].location_predicate).
  • Added test type minecraft:height_match
  • This checks the y-level of a block, returning true only if it's higher than or equal to min_inclusive and lower than or equal to .Code
  • Format: object with fields:
    • • min_inclusive - int, the minimum y value of allowed blocks (inclusive)
      • max_inclusive - int, the maximum y value of allowed blocks (inclusive)
  • Added rule test type minecraft:all_of
    • This checks a list of Rule Tests for whether all of them return true for the same block.
    • Format: object with fields:
      • rules - list of Rule Tests, the rules to test the block against.
