Ah, there you are! I’m writing this changelog on the go because there’s no time to waste. Plenty of new features from the next game drop go into testing checks watch right this second! I made us an itinerary so we can get exploring right away:

First, I suggest we hike to a chilly biome to befriend the ever-so fluffy cold cow before we trek to the sandy biomes where our auburn warm cow is kicking up dust. There, you better listen out for howling wind and other ambient desert sounds! Oh, and if you like satisfying sounds, let’s make a pitstop where there’s crunchy leaf litter! Perhaps pick some new wildflowers to bring home too? Then as night falls, we head towards water for the grand finale: the mesmerizing firefly bush with its dancing particles glimmering in the dark. And here I thought nothing could outshine my bug fixes!

Experimental Features

Features and Bug Fixes

General

• Fixed a crash that would occur on Xbox if you pressed “Cancel” in the Xbox UI when converting a world or importing a world from Retail to Preview
• In Server Authoritative movement, when Players receive a movement correction it will use the current Player speed instead of a generic one, this should give a better experience.

Technical Updates

API – Scripting

@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

• 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

• 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.
  • registerEditorExtension can be called in Early Execution.

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"
                }
              }
            }
          }
        }
      }
    }
  }
}

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

Stability and Performance
