Minecraft Preview 26.70.20

More features from the upcoming game drop are ready for testing! Create your own Minecraft music mix with the new jukebox playlists. Place a single chest over a jukebox block, fill it with discs, and your DJ set is good to go! But watch where you’re dancing, the brittle ice blocks are fragile and crack when you step on them. If you don’t move off them in time, they break. They can cover crevasse openings, so you risk falling down a winding, narrow ravine that may or may not have water at the bottom. Better bring a bucket!

And as always, we’re keen to get your feedback on these new features at feedback.minecraft.net, and you can report any bugs you find at bugs.mojang.com.

Block Components

Doors

• The upper half of a door now reports the same open_bit block state as the lower half, rather than always reporting the door as closed. This covers doors placed by players, doors generated as part of a structure, and doors in existing worlds, which are corrected the first time their chunk loads

Repeater

• Repeater blocks now expose a locked block state that is true while a powered repeater or comparator is feeding one of the repeater's side inputs
• For new worlds (base game version 1.26.60 and later), repeater locked state changes now trigger neighbor block updates for parity with Java Edition; existing worlds keep the prior client-only update behavior

Scaffolding

• Scaffolding blocks now expose a bottom block state that is true when the block below provides no support and is not another scaffolding
• For new worlds (base game version 1.26.60 and later), scaffolding bottom state changes now trigger neighbor block updates for parity with Java Edition; existing worlds keep the prior client-only update behavior

Blocks

• Fixed issue where destruction_particles and precipitation_interactions component overrides on block permutations would be ignored (MCPE-237074)

Editor

• Added support for filter icon tooltip on the Editor List View control.
• Added group sorting, dynamic height configuration and noMargins style for IListPanePropertyItem API
• Fixed a bug where the selected Chunks are not reflecting the biome changes in Biome Data Assignment Tool

• Fixed a bug where the Custom Time UI element would remain invisible if the Presets dropdown was changed by changing the Daylight Cycle dropdown
• Fixed issue that was allowing to create multiple empty layouts
• Fixed a bug where the tooltip on the action item for Layouts Management was inconsistent

Entity Components

• The minecraft:transformation component now preserves empty equipment slots when preserve_equipment is set to true
• Made schema for the minecraft:annotation.break_door component stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.60 and newer.
• Made schema for the minecraft:attack component stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.60 and newer.
  • damage now only accepts a scalar or an object with min and max values. Array values are no longer valid.
• Made schema for the minecraft:inventory component stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.60 and newer.
• Made schema for the minecraft:spell_effects component stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.60 and newer.
• The minecraft:can_stand_on_brittle_ice component enables any mob to stand on Brittle Ice without breaking it
  • Used by defining the component as follows: "minecraft:can_stand_on_brittle_ice": {}

Features

• Added the internal-only minecraft:crevasse_feature world generation feature, which carves a winding, tapered crevasse into exposed terrain
  • This feature is not currently available for use in creator content
  • The crevasse follows the terrain surface, extends in opposite directions from its placement position, and requires a minimum connected footprint before carving
    • The following fields configure generation:
      • max_length: Maximum end-to-end length in blocks, from 4 to 16; defaults to 16
      • max_width: Maximum cross-section width in blocks, from 2 to 8; defaults to 4
      • min_footprint: Minimum connected horizontal footprint required before carving, from 1 to 32 blocks; defaults to 10
      • twistiness: Amount of horizontal curvature, from 0.0 to 16.0; defaults to 4.0
      • carve_depth: Range used to select the carve depth below the origin terrain surface, from 4 to 32 blocks; defaults to [6, 10]
      • fill_depth: Range used to select the fill depth below the origin terrain surface, from 0 to 32 blocks; defaults to [4, 6]
      • surface_block: Optional block placed over the crevasse opening; omitted by default
      • fill_block: Optional block placed at or below the selected fill depth; omitted by default
  • Example code:

  "format_version": "1.26.50",
  "minecraft:crevasse_feature": {
      "identifier": "example:ice_crevasse_feature"
    "max_length": 16,
    "max_width": 4,
    "min_footprint": 10,
    "twistiness": 4.0,
    "carve_depth": {
      "range_min": 6,
      "range_max": 10
    "fill_depth": {
      "range_max": 6
    "surface_block": "minecraft:ice",
    "fill_block": "minecraft:water"
  
  

Item Components

• Items with the minecraft:damage_absorption component now absorb damage when the Unbreaking enchantment prevents durability loss (MCPE-237532)

Packs

• System packs can no longer be overridden by development packs with the same identity.

Points of Interest

• Released support for defining point-of-interest types with hierarchical tags in behavior packs
• Released /locate poi for locating registered points by type or tag

Stability and Performance

• Performance improvements for memory allocation on Android

User Interface

• Downloading Marketplace content no longer deletes development resource, behavior, or skin packs with matching UUIDs
• Malformed JSON UI in resource packs (unresolved control names, invalid anchors, unknown control types, unsolvable layouts, malformed binding expressions, and view binding loops) is now reported as a content log error
• Route transitions are now built from animation selectors with createRouteTransition, so an animation is data that can depend on the from/to navigation pair rather than a bespoke transition component
• Route transitions now live in the standalone @mojang/react-route-transition package, with the screen animation setting in @mojang/react-screen-animation, so both can be consumed without depending on @mojang/ui

Experimental Technical Updates

Entity

• Added beta Script API support for positioning entities as passengers of blocks
  • Entity.startPassengerOfBlock(blockPosition, offset, rotation, rotationLimit, emote) positions an entity as a passenger of a block, with a position offset, rotation, rotation limit, and PassengerOfBlockEmoteType (Standing, Riding, or Laying)
  • Entity.stopPassengerOfBlock() stops an entity from being a passenger of a block
  • The read-only Entity.isPassengerOfBlock property reports whether an entity is a passenger of a block
  • Destroying or changing a block does not automatically stop an entity from being its passenger; scripts must call Entity.stopPassengerOfBlock() because blocks are agnostic of their passengers
  • The existing query.is_riding returns true when an entity is riding a vehicle or is a passenger of a block in the Riding pose; the new query.is_laying returns true when an entity is a passenger of a block in the Laying pose. When isPassengerOfBlock is true and both queries are false, the entity is in the Standing pose for animation

API

• Updated the ScriptPlayer.playMusic method in beta for playing music tracks for an individual player
  • Now returns a SoundInstance when the MusicOptions.fade value is zero or not given
  • Returns undefined when the MusicOptions.fade value is greater than zero
  • Can now pass a SoundDefinition into the trackId field
• Updated the ScriptWorld.playMusic method in beta for playing music tracks for all players in the world
  • Now returns a SoundInstance when the MusicOptions.fade value is zero or not given
  • Returns undefined when the MusicOptions.fade value is greater than zero
  • Can now pass a SoundDefinition into the trackId field
• Added support for the minecraft:chiseled_bookshelf block to BlockInventoryComponent in beta
• Added ItemBlockEntityStorageComponent item component behind beta
  • It may be accessed on any item-stack
  • It has the following methods, store, release, transfer, getEntities and size which work like their BlockEntityStorageComponent counterparts
    • release however takes an extra position parameter to decide where the entity is being released
  • The component will be pre-populated if the item-stack results from a successful carry_over_block_entity_data loot function
  • Stored entities will be carried over the corresponding placed block if it supports entity-storage

CarryOverBlockEntityDataFunction

• Added the read-only beta property entityStorage to expose whether the loot function carries stored entities from the block entity to the dropped item

Blocks

• Added the optional Boolean field entity_storage to the carry_over_block_entity_data loot function, defaulting to false and requiring the Upcoming Creator Features experiment
• When entity_storage is true, stored entities are copied from the block entity to the dropped item without being released, independently of the dynamic_properties option
• Placing the dropped item restores its stored entities when the placed block supports entity storage, without releasing them
• Split BlockComponentNamedTickEvent's isName into name and isMine
  • name is a string property matching the name used when ScriptBlock.scheduleNamedTick was used
  • isMine is a method that returns true if the event was scheduled by your pack
• Added two new methods to the Block API and renamed one
  • getScheduledNamedTickCount which returns the amount of named events scheduled at a position, agnostic of pack origin
  • getAllScheduledNamedTicks which returns the vector of named events scheduled at a position by that pack
  • removeScheduledNamedTick renamed to removeScheduledNamedTicks

minecraft:block_entity

• Added the optional show_ui_on_interaction boolean to container for block format versions 1.26.20 and later with Upcoming Creator Features enabled; it defaults to true
• Setting show_ui_on_interaction to false disables the built-in container UI and allows normal block interaction events, including registered onPlayerInteract callbacks, to run instead; omitting the field or setting it to true preserves container opening without those callbacks
• Custom containers now follow chest interaction permissions, preventing container opening and interaction callbacks for players without permission to open containers, even when the UI is disabled
• Custom containers are now recognized as interactive container blocks, preventing duplicate client-side use of held items during interaction
• The HUD now shows the "Open" interaction hint for custom containers only when their UI is enabled

Entity Components

• Added a new experimental minecraft:time_marker_sensor entity component, available to entity definitions using the beta format version, which runs an entity event every time a named time marker fires on a named world clock

Features

• POI type definitions now respect behavior pack stacking order, allowing higher-priority packs to override definitions from lower-priority packs

Graphical

• Under the RenderDragon Features for Creators Experiment
  • Ice crystals now emit a light blue light color
