• Added 'minecraft:replace_biomes' component to allow for custom biomes to replace portions of vanilla biomes. To use, add to custom biome files in behavior packs

Technical Updates in Minecraft Bedrock 1.21.80.27 beta and preview

API

@minecraft/server 1.19.0

• Moved methods StructureManager.placeJigsaw and StructureManager.placeJigsawStructure from beta to 1.19.0.
• Moved interface JigsawPlaceOptions from beta to 1.19.0
• Moved interface JigsawStructurePlaceOptions from beta to 1.19.0
• Moved error class PlaceJigsawError from beta to 1.19.0

@minecraft/server 2.0.0-beta

• Coroutines (promises) are now flushed in early execution to allow async imports to interact with early execution APIs like Custom Components and Custom Commands.
• Added support for custom command enums.
• Added Enum type to CustomCommandParamType
• spawnEntity method of Dimension no longer supports using a spawn event inside the identifier parameter. SpawnEntityOptions interface now has an optional string member spawnEvent?: string for specifying a spawn event to be sent to the entity when it is spawned. Please update any existing usages of spawn events inside identifier to instead use this new spawnEvent option. For example:
• spawnEntity("minecraft:horse<minecraft:ageable_grow_up>", {x:0, y:0, z:0}) should become spawnEntity("minecraft:horse", {x:0, y:0, z:0}, {spawnEvent: 'minecraft:ageable_grow_up'})
• EntityGroundOffsetComponent has been remove
• Block method getComponent will return BlockCustomComponentInstance for custom components registered with BlockComponentRegistry in 2.0.0

@minecraft/server-ui 2.0.0-beta

• Class ModalFormResponse
• Changed type for formValues property from (boolean | number | string)[] to (boolean | number | string | undefined)[].
• - New Signature: formValues?: (boolean | number | string | undefined)[].
• - Old Signature: formValues?: (boolean | number | string)[].
• formValues array now contains entries for all the elements provided by the request. It means that labels, headers, and dividers are considered into the response with an undefined value.

Block Components

• Fixed isotropic textures in "minecraft:material_instances" being squashed and stretched for non-square faces

Blocks

• New field "condition" added to the culling rules schema. It provides more control over which neighbor blocks will trigger a face or part to be culled.
• The supported values are "default", "same_culling_layer", "same_block" and "same_block_permutation".
• "default" will pass the condition if the neighbor block is full and opaque
• All conditions are an extension of "default", meaning a full and opaque neighbor will always be a passing condition, before the extended "same_*" condition is checked
• "same_culling_layer" will pass the condition if the neighbor block shares the same "culling_layer" as the block being occluded, defined in the geometry component
• If either of the culling layers being compared is "minecraft:culling_layer.undefined", the condition will never pass
• "same_block" will pass the condition if the neighbor block has the same identifier
• "same_block_permutation" will pass the condition if the neighbor block has the same identifier and is the exact same permutation
• Additionally, the feature is currently only usable behind the "upcoming creator features" toggle.
• New field "culling_layer" added to the block's geometry component. It allows different blocks to be grouped together when using the "same_culling_layer" condition in a culling rules file.
• When using the minecraft namespace, the only allowed culling layer identifiers are : "minecraft:culling_layer.undefined" or "minecraft:culling_layer.leaves".
• Additionally, the feature is currently only usable behind the "upcoming creator features" toggle.

Components

• Content errors will log missing entity references in the "minecraft:entity_placer" and "minecraft:projectile" item components

Editor

• Fixed a bug where moving a structure to the clipboard while in Paste Preview (with no actual active clipboard) did not update the clipboard client widget
• Fixed some bugs around freehand selection with very large volumes
• Capped some of the brush volume max sizes so that they don't exceed our max voxel count for selection operations
• Fixed a bug where a number of script widget errors would fire when entering The Nether as the startup dimension at Editor open
• Fixed a bug that caused mouse cursor to be released when changing to Crosshair mode
• Adding an animation on the viewport and opening the log panel when an error is logged.
• Re-organized core modal tools in tool rail
• Added an indicator to the 3D Block Cursor to show the face that the mouse is pointing at
• Added a new tutorial flow which can be activated from Help menu

Structures

• Trail ruins generate at the same location in Mutated Birch Forests between Java and Bedrock on the same world seed
