General

Performance

Technical

AI Goals

• Made the schemas for the following stricter when parsing, now will fail to load an entity json that has invalid data in versions 1.26.30 and newer:
  • Template:Cd
  • Template:Cd
  • Template:Cd
  • Template:Cd
  • Template:Cd
  • Template:Cd
  • Template:Cd
    • Int Range field Template:Cd now only accepts an object with Template:Cd and Template:Cd values. Other formats will fail to parse.
  • Template:Cd
  • Template:Cd
  • Template:Cd

Blocks

• Released the Template:Cd field in the Template:Cd component from behind the Voxel Shapes experiment. Non-unit-cube culling shapes for certain blocks (e.g. Minecraft:fences, Minecraft:bells, Minecraft:slabs) still require the experiment.
• Released the snow logging behavior for Block Precipitation Interaction component out of experimental.

DDUI

• Replaced Template:Cd with Template:Cd, Template:Cd, Template:Cd, and Template:Cd.
• Renamed Template:Cd to Template:Cd.
• Changed some values of Template:Cd:
  • Template:Cd to Template:Cd.
  • Template:Cd to Template:Cd.

Entity

• Released the Template:Cd entity event response out of experimental.

Events

• Added Template:Cd and Template:Cd to Template:Cd.

Features

• Added a new feature type Template:Cd.
  • This feature is meant to be used as a filter to filter away positions based on height differences close to the placed feature.
  • Template:Cd - Specifies the minimum height difference required upwards.
  • Template:Cd - Specifies the minimum height difference required downwards.
  • Template:Cd - Specifies the maximum height difference allowed upwards.
  • Template:Cd - Specifies the maximum height difference allowed downwards.
  • Template:Cd - Specifies the length in each cardinal direction the filter will check for blocks against the given differences.
  • Template:Cd - Specifies what feature should be placed when filter succeeds.
• Added an Template:Cd field to the Template:Cd constraint of Template:Cd.
  • When Template:Cd, only motion-blocking blocks within the structure are checked for intersections against the Template:Cd.
  • When Template:Cd, all blocks in the structure except empty ones are checked for intersections, including air.
  • Defaults to Template:Cd, preserving existing behavior.
  • Motion-blocking blocks are full blocks that block motion.
• Added the Template:Cd field to Template:Cd.
  • Specifies which Y coordinate of the structure is considered its ground level.
  • Used as a vertical offset during placement and determines which layer of the structure is checked by the Template:Cd and Template:Cd constraints.
  • All non-air blocks at this level define positions where the Template:Cd and Template:Cd constraints are checked.
  • If the value exceeds the structure's height, it is clamped to the maximum valid value and a content warning is emitted.
  • Defaults to Template:Cd.
• Added a new Template:Cd option to the Template:Cd field of Template:Cd.
  • When specified, ensures the structure's ground level is placed on mostly flat terrain.
  • Includes a Template:Cd field that defines the maximum allowed height difference between the placement position and terrain samples taken at the structure's ground level.
    • A valid terrain sample consists of a solid block with a non-solid block above it.
    • Defaults to Template:Cd.

Minecraft:Scripting

• Released the Template:Cd method in Template:Cd from Template:Cd to 2.8.0.

Experimental

These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", "Experimental Custom Projectile Features", and "Experimental Voxel Shape Features" Minecraft:experimental toggles.

Changes

Technical

Minecraft:API

• Added the new Template:Cd classes to Template:Cd library:
  • Template:Cd

Blocks

• Added the Template:Cd field to the Template:Cd component under Upcoming Creator Features.
  • Supported values are Template:Cd and Template:Cd.
  • When set to Template:Cd, the block is considered when lava attempts to spread fire after adjacent block updates, while still respecting normal fire placement rules.
  • When set to Template:Cd, the block is excluded from that check.

General

• Added the Template:Cd field to the projectile component.

Voxel Shapes

• Added occlusion voxel shapes for wall-mounted skull blocks when the Voxel Shapes experiment is enabled.
  • These shapes improve face culling so that hidden faces of custom blocks are correctly removed when a skull block is attached:
    • Wall-mounted skull shapes (6 blocks): Minecraft:Creeper Head, Minecraft:Dragon Head, Minecraft:Player Head, Minecraft:Skeleton Skull, Minecraft:Wither Skeleton Skull, Minecraft:Zombie Head
    • Wall-mounted Piglin shape (1 block): Minecraft:Piglin Head
