  "minecraft:cubemap_settings": {
  "description": {
  "identifier": "mypack:mycubemap"

Item Components

• Added the minecraft:swing_sounds item component

  • Allows overriding the swing sounds emitted by the user
  • Fields:
    • "attack_miss": sound played when an attack misses or deals no damage due to invulnerability
    • "attack_hit": sound played when an attack hits
    • "attack_critical_hit": sound played when an attack hits and deals critical damage
  • At least one field needs to be specified

• Added the minecraft:kinetic_weapon item component

  • Description:
    • Allows an item to deal damage and other effects every tick while in use, to all unobstructed targets found in a straight line from the user's view vector
    • Damage is computed based on both the user's and target's velocity projected onto the view vector (via dot product)
    • The more the user and target move toward each other and align with the view vector, the higher the damage
    • After applying "damage_multiplier" and "damage_modifier", the resulting damage is floored to the nearest lower integer
  • Fields:
    • "delay": Ticks to wait before applying damage and effects
    • "reach": Range along the view vector where entities can be hit
    • "hitbox_size": Extra tolerance on the raycast to detect entities
    • "damage_multiplier": Multiplies the sum of the projected velocities
    • "damage_modifier": Adds to the multiplied sum of the projected velocities
    • "damage_conditions": Conditions that need to be satisfied for damage to be applied
    • "knockback_conditions": Conditions that need to be satisfied for knockback to be applied
    • "dismount_conditions": Conditions that need to be satisfied for riders to be dismounted
  • "damage_conditions", "knockback_conditions" and "dismount_conditions" fields:
    • "max_duration": Time, in ticks, during which the effect can be applied after "delay" elapses
    • "min_speed": Minimum user's speed (projected onto the view vector via a dot product) required for the effect to be applied
    • "min_relative_speed": Minimum relative speed of the user with respect to the target (projected onto the view vector via a dot product) required for the effect to be applied
    • If omitted, the corresponding effect does not apply
  • Requirements:
    • Requires the "minecraft:use_modifiers" item component on the same item

• Added the "minecraft:piercing_weapon" item component

  • Description:
    • Allows an item to deal damage to all entities detected in a straight line along the user's view vector
    • Items with this component cannot destroy blocks, as the attack action always takes priority, regardless of what the user is looking at
  • Fields:
    • "reach": Range along the view vector where entities can be hit
    • "hitbox_size": Extra tolerance on the raycast to detect entities
  • Requirements:

• The "minecraft:cooldown" item component now supports a "type" field

  • Defines the action the cooldown applies to, in a mutually exclusive way, so cooldowns for one action type do not affect the other
  • Values:
    • "use": puts the item on cooldown when used, preventing further use until it expires, but still allowing attacks, mining, and interaction
    • "attack": puts the item on cooldown when attacking, preventing further attacks until it expires, but still allowing use, mining, and interaction
  • "use" is the default value, preserving the component's original behavior

Molang

• Added four new Molang queries pertaining to the minecraft:on_use_kinetic_damage item component:

  • query.get_kinetic_item_damage_duration, Returns the damage_duration value from the main-hand item's minecraft:on_use_kinetic_damage component, or 0 if the component is not present
  • query.get_kinetic_item_knockback_duration, Returns the knockback_duration value from the main-hand item's minecraft:on_use_kinetic_damage component, or 0 if the component is not present
  • query.get_kinetic_item_dismount_duration, Returns the dismount_duration value from the main-hand item's minecraft:on_use_kinetic_damage component, or 0 if the component is not present

• Added "query.kinetic_weapon_delay", which returns the "delay" value from the main-hand item's "minecraft:kinetic_weapon" component, or 0 if the component is not present

• Added "query.kinetic_weapon_damage_duration", which returns the "max_duration" value of "damage_conditions" from the main-hand item's "minecraft:kinetic_weapon" component, or 0 if the component is not present

• Added "query.ticks_since_last_kinetic_weapon_hit", which returns the number of ticks elapsed since the user last hit something while using a kinetic weapon

  • Returns -1.0 if no kinetic weapon is being used or if nothing has been hit yet
  • Hits that occur while the user is unloaded are not counted

Network Protocol

Experimental Technical Updates

API

• Debug drawing tech in @minecraft/debug-utilities now supports rendering shapes in different dimensions:

  • Added setLocation(location: minecraftserver.DimensionLocation | minecraftserver.Vector3): void method to DebugShape
  • The location property on DebugShape has been changed to read only (use setLocation above to modify the location)
  • Added dimension readonly property to DebugShape
  • Changed the constructors of all the debug shapes to instead take a variant of Vector3 or DimensionLocation

• Fixed triggering of PlayerSwingStartAfterEvent to only happen on the start of a swing

• Fixed issue where onBreak beta API event would not fire if a Piston was the breaking cause

• Released @minecraft/server version 2.4.0

• Added @minecraft/server version 2.5.0-beta

API Infra

• Modernized CommandOutputPacket serialization
  • Max number of "Output Messages" set max to 100
    • Field "Message Id", set max size to 512 characters
    • Max number of "Parameters" set to 512
• Modernized CommandRequestPacket serialization
  • Field "Request ID", set max size to 39 characters

Blocks

• Added component minecraft:support behind the Upcoming Creator Features toggle

Example:

"minecraft:support": {
"shape": "stair" // "fence" is also valid
}

• Created a new block trait, minecraft:connection, to expose behavior like Fences or Glass Panes from Vanilla where blocks connect to other blocks around them. Using this trait with the example below adds the bool states minecraft:connection_north, minecraft:connection_east, minecraft:connection_south, and minecraft:connection_west. This is only available while the "Upcoming Creator Features" toggle is enabled

Example:

{
"format_version": "1.21.130",
"minecraft:block": {
"description": {
"identifier": "test:connection_block",
"traits": {
"minecraft:connection": {
"enabled_states": ["minecraft:cardinal_connections"]
}
}
}
}
}

• One known issue with this is that blocks using minecraft:connection don't properly decide connections to blocks like Fences, Walls, Iron Bars, Fence Gates, and Glass Panes. Addressing this issue is currently in development
