API - Scripting​

  • Unhandled rejected promises in scripting now include callstacks when logged.

@minecraft/server 1.18.0​

  • Renamed system.scriptEvent to system.sendScriptEvent

  • Moved NamespaceNameErrorReason from beta to @minecraft/server 1.18.0

  • Moved system.sendScriptEvent from beta to @minecraft/server 1.18.0

  • Moved NamespaceNameError from beta to @minecraft/server 1.18.0

  • Released InputInfo.getButtonState, InputButton, and ButtonState to @minecraft/server 1.18.0

  • Released InputInfo.getMovementVector to @minecraft/server 1.18.0

  • Released PlayerButtonInputAfterEvent, AfterEvents.playerButtonInput and InputEventOptions to @minecraft/server 1.18.0

  • Several APIs have been given the Readonly permission, which allows them to now be called inside Before Event callbacks.

    • All methods for BlockVolume.
    • All methods for Vector.

  • Changed spawnEntity method on Dimension to now take a variant of either a string or EntityType.

  • Added placeFeature and placeFeatureRule APIs to the Dimension class

  • Added isValid property to the Camera class.

Biomes​

  • Fix client_biome loading so grass_appearance and foliage_appearance settings are added if not specified when format_version is lower than 1.21.60 (MCPE-189816)

Blocks​

  • water and lava no longer will turn into flowing_water or flowing_lava when neighbor updates happen. water and lava now will respond to queued ticks without needing to change into another block

  • The minecraft:map_color component underwent a schema change

    • It is now a JSON object with two fields "color" and "tint_method".

    • "color" is a required string field expecting an HEX representation of the RGB, prefixed with a # character.

    • "tint_method" is a string field that multiplies the color with a predefined tint. Supported values are "none, "default_foliage", "birch_foliage", "evergreen_foliage", "grass" and "water".

    • the old schema format is still supported for convenience.
      Examples:

      "minecraft:map_color": { "color": "#ABCDEF", "tint_method": "grass" }

      or

      "minecraft:map_color": { "color": "#ABCDEF" }

      or

      "minecraft:map_color": "#ABCDEF"

Components​

  • Added the 'minecraft:replaceable' component which determines if a new block can replace the existing block at a particular position. If the component is not added to a block it is not replaceable.

Components​

  • Multiple components that used effect durations can now be set to "infinite" including:

    • "minecraft:attack": "effect_duration"
    • "minecraft:healable": "duration" in the "effects" list
    • "minecraft:mob_effect": "effect_time"
    • "minecraft:projectile": "durationeasy", "durationnormal", and "durationhard" can now all use "infinite"
    • "minecraft:food": "duration" in the "effects" list
    • "minecraft:spell_effects": "duration" in the "add_effects" list
    • "minecraft:combat_regeneration": "regeneration_duration"

Editor​

  • Shulker box's textures are fixed in Block picker and lists

  • Fixed a bug that excluded some blocks from block picker list with partial text search

  • Block picker search text field will have UI focus when modal opens

  • Line Tool: Left Click no longer clears the line if two points already exist. Left Click now behaves the same as Shift + Left Click and always adds points to the existing line.

  • Added cursor support for selecting invisible blocks when the Show Invisible Blocks setting is enabled

  • Added IPropertyPane.addProgressIndicator API function to display a spinner or a progress bar property item

  • Added ImageAnimationData API type to represent a sprite sheet animation for images

  • Added iconAnimation: ImageAnimationData property to IActionBarItemCreationParams API

  • Added IPropertyPane.addLink API function to create link buttons in panes.

  • Added system.isEditorWorld property into @minecraft/server in beta

  • Now using minecraft/server 2.0.0-beta, see API section for more details on 2.0.0-beta.

Entities​

  • Fixed issue where No more entities assert failure occurred when flying through biomes during a storm

Jigsaw​

  • Fixed world_surface type of heightmap_projection in minecraft:jigsaw to generate on top of water and leaf blocks.

JSON Events​

  • The parameter "duration" in the "add_mob_effect" event can now be set to "infinite"

Sounds​

  • Added support for entity sound variants

    • Entity sounds now have a "variants" field which defines sound variants based on the runtime entity
    • Variants has a "key" field reading a Molang expression returning a string to select sound variant (eg: querying an enum entity property).
    • Variants has a "map" field which contains key-value pairs of a variant identifier and the sound events it overrides.
    • When playing a sound for an entity we first try to calculate their variant and see if that variant overrides the sound event, if not we play the sound form the base entity. If that fails we fall back to the existing logic of running from "defaults".
      Example:
      Given a mob with the following property

    "minecraft:emotional_state": { "type": "enum", "values": [ "neutral", "angry", "happy", "sad" ], "default": "neutral", "client_sync": true }

Sound variants can be played by querying the property:

{ "entity_sounds": { "entities": { "test_mob": { "volume": 1.0, "pitch": 1.0, // The base sounds for various events "events": { "ambient": "mob.test_mob.ambient", "death": "mob.test_mob.death", "step": { "sound": "mob.test_mob.step", "volume": 0.8, "pitch": 1.0 }, "attack": "mob.test_mob.attack" }, "variants": { // Key returning the enum string for variants, can use any Molang expression resulting in a string "key": "query.property('minecraft:emotional_state')", "map": { // If a resulting variant key is not handled here then it will use the base sounds "neutral": { "volume": 1.0, "pitch": 1.0, "events": { // If an event is not handled in a variant then it will use the base sound "death": "mob.test_mob.death.netural" } }, "angry": { "volume": 1.0, "pitch": 1.0, "events": { // Variants can override different events than other variants "death": "mob.test_mob.death.angry", "ambient": "mob.test_mob.ambient.angry" } } } } } } } } }

Experimental Features

API - Scripting​

@minecraft/server 2.0.0-beta​

The beta for @minecraft/server has been updated to 2.0.0-beta. This signifies that breaking changes have occurred, largely related to script execution timing. Version 1.X will continue to function as-is.

Visit our documentation portal  for more information in the near future.

  • Added new privilege EarlyExecution

    • 2.0.0-beta and higher now executes with the early execution privilege, scripting below 2.0.0-beta will continue to execute without early execution
    • All after and before event signals subscribeandunsubscribe` methods can now be called in early execution
    • The following System methods can now be called in early execution
      • clearJob
      • clearRun
      • run
      • runInterval
      • runJob
      • runTimeout
      • waitTicks
    • BlockComponentRegistry method registerCustomComponent can now be called in early execution

  • applyKnockback method now takes a VectorXZ parameter for the knockback horizontal force (which includes the strength/magnitude), as well as a vertical strength parameter. To convert from V1, you should normalize your previous direction vector and multiply it by the old horizontal strength value. Vertical strength is the same as before.

  • EffectType

    • getName method now always returns the minecraft: namespace prefix along with the name

  • Effect

Graphical​

  • Added a new version (1.21.70) for the lighting JSON schema in the Deferred Technical Preview. This new version adds support for controlling the intensity of sky light, which affects both the contribution of legacy sky lighting as well as sky reflections. See updated documentation on the Learning Portal for more details.

    • This object snippet can be added to lighting/global.json under the minecraft:lighting_settings object to control the sky intensity

    "sky": { "intensity": 1.0 // Float value between [0.1 - 1.0] }

  • Fixed a bug with water surface rendering that caused specular highlights to be much lower than they should have been in the Deferred Technical Preview.

Stability and Performance​

  • Resolve crash when changing point light shadow settings under Deferred Graphical Settings
