Minecraft 26.1 Pre-Release 1

Changes

• Updated the Main Menu background panorama

Technical Changes

• The Data Pack version is now 101
• The Resource Pack version is now 84
• Changes to the minecraft:nbt text component format
• Changes to the minecraft:selector, minecraft:nbt and minecraft:object text component formats

Data Pack Version 101

• The “Default Components” report generator no longer outputs files for entries without any components

Commands

Changes to time

Syntax:

• time [of <clock>] rate <rate> – sets the rate multiplier at which the clock should advance
  • Note: this only changes the rate at which the World Clock and any Timelines dependent on it advance their internal timers
    • For example, in the case of the minecraft:overworld clock, the day/night cycle will pass quicker with a larger value, but actual game simulation will not speed up (as would happen with /tick rate)
  • A rate of 1 corresponds to normal speed
  • rate is a float between 0 (exclusive) and 1000 (inclusive)

Data Components

Modified minecraft:provides_banner_patterns

• The component now also accepts an ID or a list of IDs in addition to a tag

Modified minecraft:blocks_attacks

• The field bypassed_by now also accepts an ID or a list of IDs in addition to a tag

Modified minecraft:damage_resistant

• The field types now also accepts an ID or a list of IDs in addition to a tag

Loot Functions

Changed minecraft:set_instrument

• The options field now also accepts an ID and a list of IDs in addition to a tag

Predicates

Added minecraft:environment_attribute_check Loot Predicate

Exactly matches the value of an Environment Attribute at a given position. Note: this predicate requires a context with an origin position set as long as the Environment Attribute can vary positionally.

Format: object with fields:

• attribute – Environment Attribute ID to test
• value – Exact value of the Environment Attribute to match
• e.g. {condition: ‘environment_attribute_check’, attribute: ‘gameplay/piglins_zombify’, value: true}

Number Providers

Added minecraft:environment_attribute

Fetches and provides the value of an Environment Attribute (that can be represented as a number). Note: this provider requires a context with an origin position set as long as the Environment Attribute can vary positionally.

Format: object with fields:

• attribute – Environment Attribute ID to fetch
• e.g. {type: ‘environment_attribute’, attribute: ‘gameplay/sky_light_level’}

World Generation

Flower Features

• Features spawned from Bone Meal are no longer restricted to the flower feature type, and instead controlled by the #can_spawn_from_bone_meal Configured Feature Tag
• The flower, flower_no_bonemeal, and random_patch feature types have been removed
  • Instead, patches can be expressed as a sequence of count and random_offset placement modifiers

Int Providers

Added trapezoid Int Provider

Select a random value with a trapezoid distribution, similar to the trapezoid Float Provider.

Format: object with fields:

• min: integer, the minimum value to generate
• max: integer, the maximum value to generate
• plateau: integer, the width of the “plateau” of the distribution in which all values are equally likely to occur
  • A value of 0 is equivalent to a triangle distribution
  • A value of max-min is equivalent to a uniform distribution

Tags

Configured Feature Tags

• Added #can_spawn_from_bone_meal – features that, when added in a biome, can be spawned when using Bone Meal in that biome

Text components

`minecraft:object

• Added a new optional field named fallback that contains a text component to be used when object component itself can’t be displayed (for example when printing messages in server logs or during narration)
• Objects of type player (player heads) no longer can be used in server status messages (MotD)
  • All components of that type will be replaced by a fallback text

Resource Pack Version 84

• Updated textures for Pup to fix issues with overlapping textures

Item Models

minecraft:end_cube Special Model Type

• New special model type that renders a cube with the same texture effects as the End Portal and the End Gateway blocks
• Fields:
  • effect – texture effect to apply, one of: portal, gateway

Block State Rendering

• End Gateway and End Portal should now look the same when rendered on a Block Display as they look when placed in world

Shaders & Post-process Effects

• The core/rendertype_translucent_moving_block shaders have been removed in favor of core/block
