Potent sulfur

• Geyser eruptions emit game events at the beginning and at the end of the eruption that can be detected by sculk sensors.

Sulfur cube

• Sulfur cube archetypes
  • New archetype: Slow Bouncy
    • Slow speed, high bounciness, medium friction and medium air drag.
    • It is buoyant.

Sulfur caves

• Redesigned all surface sulfur springs features.
• Is now less likely to generate underneath oceans, hills or mountains.
• No longer generate with bands of tuff and granite.

Configured features

  • Randomly selects one of the given features to generate based on their weights.
  • Format: object with fields:
  • features - list of placed features and their weights.

• Changed minecraft:large_dripstone
  • The maximum allowed value for column_radius has been reduced from 19 to 16 to prevent features from reaching beyond neighboring chunks.
  • Wind offset is now clamped to ensure the full dripstone (radius + wind) stays within neighboring chunk bounds.

• Changed minecraft:root_system
  • New field level_test_distance indicating how far away from the origin the root system will check the existing terrain.
  • New field max_level_deviation indicating how far the ground level can deviate from the original ground level at these test positions.

Data pack

• The pack format version is now 105.0.

Identifiers

• Added minecraft:sulfur_cube_archetype registry entries:
  • hot
  • slow_bouncy
• The entry format for minecraft:sulfur_cube_archetype registry has been updated:
  • explosion_fuse has been replaced by explosion: an optional field, if present, the sulfur cube of this archetype will explode:
    • fuse: positive integer, the fuse time when ignited.
    • power: non-negative integer, the explosion power.
    • causes_fire: boolean, whether the explosion causes fire.
  • Added contact_damage: an optional field, if present, the sulfur cube of this archetype will deal damage to entities when they come in contact with it:
    • amount: non-negative float, amount of damage dealt.
    • damage_type: damage type.
    • attribute_to_source: boolean indicating if the damage is attributed to the sulfur cube.
  • Added knockback_modifiers: a field that contains various modifier fields for the sulfur cubes knockback magnitude and direction.
    • horizontal_power: float that represents the horizontal power of the knockback.
    • vertical_power: float that represents the vertical power of the knockback.
• Removed the HurtByTimestamp tag from Living Entities, ticks_since_last_hurt_by_mob should be used instead.

Sounds

• Updated eruption sounds for sulfur springs.

Structure definition

• Changed the minecraft:block_rot structure processor.
  • Now evaluates the block state produced by previous block processors in the chain, instead of always using the original block defined in the structure.
  • The first processor in the chain still always evaluates against the original structure-defined block.

Surface rules

• Changed the noise_threshold surface rule condition.
  • Added the is_3d field - boolean, true if the noise should be evaluated in 3D.
  • If not specified, defaults to false.
• Removed the noise_gradient surface rule.
  • Can be replaced with noise_threshold.

Tags

• Added #sulfur_cube_archetype/hot, and #sulfur_cube_archetype/slow_bouncy to #sulfur_cube_swallowable item tag.
