Minecraft Bedrock 1.26.10 Update Notes for Creators

Video version of this article from the Minecraft Creator Channel

Minecraft Bedrock has been updated to 1.26.10 - the Tiny Takeover game drop! While players revel in adorable new baby mob models, creators get a significant wave of API releases and updated entity components. The following features do not require experimental toggles unless otherwise specified.

Camera

Camera splines and attach-to-entity APIs are now out of experimental, available in @minecraft/server v2.6.0.

Blocks

Corner Stair Fix

Blocks using the minecraft:corner_and_cardinal_direction value of minecraft:placement_direction now correctly form inner corners when adjacent to other stairs.

Geometry Rotation Fix

Fixed rotation for blocks in item frames that use "minecraft:geometry.full_block" for format_version >= 1.26.0.

Block Placer Aligned Placement

The minecraft:block_placer item component has a new boolean field aligned_placement:

• When true, block placement through this item is aligned while holding the interaction button
• Defaults to false
• Supported from format_version 1.26.0 onward

Liquid Detection

• minecraft:liquid_detection component containing an empty array will now fail to load and produce a content error
• Fixed placement_filter and block_placer components to support placing on liquid blocks when used with liquid_clipped

Ambient Occlusion

• Custom blocks with ambient occlusion disabled no longer have the occasional black vertex issue
• Improved ambient occlusion for blocks using custom geometry

Other Block Fixes

• Fixed client crash on world load from out-of-bounds minecraft:geometry in the minecraft:item_visual component
• Corner stairs next to a stair block of a different type will no longer leak water for worlds of base_game_version 26.10 or higher

Items

Custom Item Cooldowns

Cooldowns on custom items now visualize correctly.

Entity Components

Ageable Growth Control

Added the ability to pause and reset growth of entities using minecraft:ageable with specified items:

• New field pause_growth_items — a list of items that can be fed to pause growth for baby entities
• New field reset_growth_items — a list of items that can be fed to reset growth for baby entities
• New ActorDefinitionTrigger field reset_growth — triggers an event when aging is reset
• New ActorDefinitionTrigger field pause_growth — triggers an event when aging is paused

Pushable Component Split

The minecraft:pushable component has been split into two new components:

• minecraft:pushable_by_block: Equivalent to "is_pushable_by_piston": true. If present, Pistons and Shulker Boxes can push the entity.
• minecraft:pushable_by_entity: Equivalent to "is_pushable": true. If present, other entities can push it.

The original minecraft:pushable component will no longer be parsed.

Buoyant Component Updates

The minecraft:buoyant component has been updated:

• The simulate_waves field has been replaced with movement_type, which accepts:
  • "waves" — moves up and down based on speed (default)
  • "bobbing" — moves up and down at a constant pace
  • "none" — no wave movement
• big_wave_probability and big_wave_speed only apply when movement_type is "waves"
• New field can_auto_step_from_liquid — defines whether the entity can step out of liquid onto neighboring solid blocks when pushed against them

Entity Filter: is_tamed

Added the is_tamed entity filter, which checks if the subject entity is tamed.

JSON Schema

Updated the canopy_decorator schema to support placing several blocks in a row as a decorator. New format uses decoration_blocks_sequence as a list of blocks with a count per block. The old decoration_block and num_steps format is still supported, but the new format takes priority when both are present.

"canopy_decoration": {
 "decoration_blocks_sequence": [
 {
 "block": "minecraft:bedrock",
 "count": 1
 },
 {
 "block": "minecraft:dirt",
 "count": [1, 2]
 },
 {
 "block": "minecraft:stone",
 "count": {
 "range_min": 1,
 "range_max": 2
 }
 }
 ],
 "decoration_chance": {
 "numerator": 1,
 "denominator": 4
 },
 "step_direction": "out"
}

Experimental Features

Scripting API Beta (@minecraft/server v2.7.0-beta)

Data-Driven UI (DDUI) Framework

This release introduces new Data-Driven UI capabilities. These APIs provide a new way to create modal forms with new capabilities and an updated appearance. New modal forms is the first step in the creator UI journey.

• CustomForm and MessageBox classes for creating modal UI
• Observable class — fires change events when wrapped data changes; used for syncing data between client and server
• UIRawMessage interface for localizable messages
• CustomForm.show() returns Promise<boolean> (true = shown, false = not shown)
• CustomForm.isShowing() and MessageBox.isShowing() added
• MessageBox.create() now takes a title parameter directly
• CustomForm.label() method added; LabelOptions renamed to TextOptions

Known Issues:

• You need to wait a tick between programmatically closing a CustomForm/MessageBox and opening another
• Showing a form while UI is already up queues the UI instead of failing
• CustomForms only update after being shown via Observables — you cannot add new controls while the form is shown
• /reload command now closes all Data Driven UI screens

Entity APIs

• Entity.addItem for directly giving items to a mob or player
• Block.getParts returns an array of block parts if the block has the minecraft:multi_block trait

Locator Bar and Waypoints

A new suite of classes for managing waypoints on a player's locator bar:

• LocatorBar class — manages the collection of waypoints
• Waypoint, EntityWaypoint, PlayerWaypoint, LocationWaypoint classes
• WaypointTexture enum and WaypointTextureBounds / WaypointTextureSelector interfaces
• EntityVisibilityRules / PlayerVisibilityRules interfaces
• LocatorBarError / InvalidWaypointError / InvalidWaypointTextureSelectorError error classes

Dedicated Server APIs (@minecraft/server-admin beta)

• DedicatedServerUtils for dedicated server-only APIs
• LevelStorage / LevelStorageQuerySnapshotFile for save state management
• AllowList for dedicated server allow list management

TickingAreaManager

• createTickingArea() now returns Promise<void> instead of Promise<TickingArea>

Debug Shape Fixes

• Fixed DebugBox position to use center instead of bottom-left corner
• Fixed DebugShape.attachedTo unintentionally using height offset

Other Beta Fixes

• Fixed EntityHurtBeforeEvent.cancel to prevent knockback sources (sprint bonus, enchantment, mace smash, projectiles) when set to true
• Added minimum/maximum bounds to several APIs
• ScriptSetBannerDetailsFunction now includes base color and pattern data

Blocks (Experimental)

Voxel Shapes

Added experimental toggle "Voxel Shapes" which enables the use of voxel shapes on vanilla and custom blocks:

• Voxel shapes are currently only used for occlusion/culling
• Added culling_shape field to minecraft:geometry component (behind VoxelShapes toggle)
• Individual boxes must be within bounds of (-14, -14, -14) to (30, 30, 30) pixels
• At least one box must overlap the base block (0–16 pixels on all axes)
• Total shape extent cannot exceed 30 pixels on any axis

Block Entity Events

Blocks can handle entity events in scripting through the onEntity handler:

• Custom named events: on_home, on_escape, on_reach, on_place, on_take
• Custom blocks may receive these events up to one tick after emission

Multi Block Trait (Upcoming Creator Features)

Added minecraft:multi_block block trait behind the Upcoming Creator Features experiment. This trait allows a single block definition to span multiple block positions, treating all parts as a unified block (like Doors). Key details:

• Enables the new minecraft:multi_block_part state
• The direction property defines which direction parts are placed ("up" or "down")
• The optional part_count property sets the number of parts (range: 2–4)
• Setting "minecraft:selection_box": true automatically combines AABBs from each part into a combined outline
• Component minecraft:movable must be defined and cannot be in permutations; valid movement_type values are "popped" or "immovable"
• Component minecraft:placement_filter cannot be defined in permutations

 "render_method": "alpha_test_single_sided"
 }
 }
 }
 }
 ]
 }
}

Chest Obstruction Component (Upcoming Creator Features)

Added minecraft:chest_obstruction component:

• obstruction_rule defines how a block above a chest affects its opening:
  • "always" — always obstructs
  • "never" — never obstructs
  • "shape" — uses the block's AABB to determine obstruction (default)

Graphical (Experimental)

• Removed the legacy point_lights/global.json format in the "Render Dragon for Creators" experiment — creators should migrate to local_lighting/local_lighting.json
• Began rollout of texture streaming feature (available in Preview for some devices; toggled off by default in Video Settings)

Rendering

• Armor attachables for Players now use a new render controller: controller.render.armor.player

What's Next

Looking ahead, here's what you can expect coming in future releases:

• Data-Driven UI (DDUI) modal presets & continued expansion with more controls and form types
• Multi block command inspection and API support
• Features in Jigsaw pools
• Snow layering in custom blocks
• Locator bar and waypoint APIs
