Minecraft 26.4 Snapshot 6
It's getting chilly in here! This week's 26.4 Snapshot 6 brings snow bricks, a new set of building blocks for anyone who wants their builds to look even cooler ;) We're also adding a new archetype to the Sulfur Cube family: the Cold Sulfur Cube. It's a frosty little friend that knows a thing or two about ice.
Stay cool and happy building!
New Features#
- Added Snow Bricks
- Added new Cold Sulfur Cube archetype
Snow Bricks#
- Snow Bricks can be crafted from 2x2 Snow Blocks
- Snow Bricks have a Slab, Stair, and Wall variant
- A Stonecutter cannot be used to craft Snow Brick Slabs, Stairs, and Walls
- Snow Bricks belong to the Fast Sliding Sulfur Cube archetype
- Snow Bricks only drop themselves if mined with a Shovel
Cold Sulfur Cube Archetype#
- A new Sulfur Cube archetype that belongs to the special archetype category
- It has the same properties as the Fast Sliding archetype, but floats and replaces water below it with a disk of Frosted Ice when it moves, similar to the Frost Walker enchantment
- Air blocks above the water block are required for Frosted Ice placement
- Will only place Frosted Ice if the Sulfur Cube starts its movement while it is on ground
- Used when the Sulfur Cube absorbs a Blue Ice block
Changes#
- Changed the default JVM options
- Mobs falling through lava may take slightly less fall damage in some cases
Minor Tweaks to Blocks, Items and Entities#
- All Packed Ice Brick variants will now require a pickaxe to be mined in order to drop themselves
- Brittle Ice will no longer crack when a Stray is standing on top of it
Sounds#
- Added ambient sounds to Ice Crystals
- An Ice crystal block has a chance of playing an ambient sound if it has a block of packed ice below
Default JVM Options#
- The game now automatically sets its Java heap size based on your system's RAM, using up to 25% with a maximum of 4 GB
Technical Changes#
- The Data Pack version is now 125.1
- The Resource Pack version is now 101.0
Data Pack Version 125.1#
Sulfur Cube Archetypes#
- Added new
location_based_effects field - an optional list of location-based effects- The format for each entry is exactly the same as a location-based enchantment effect
- Level-based values in this definition will always be evaluated with level
1
World Generation#
Density Functions#
Changed gradient#
- The
from_coordinate and to_coordinate fields now additionally accept a Vertical Anchor, as long as axis is y
Added domain_warp#
Samples an input function by applying an offset to each sampled coordinate.
Note: if the offsets change rapidly by large amount, performance may degrade significantly. This function should be used sparingly.
Format: object with fields:
input - Density Function, the input function to sampleoffset_x - Density Function, the offset to apply to sampled X coordinates- The result is implicitly truncated to an integer
- If not specified, defaults to:
0.0
offset_y - Density Function, the offset to apply to sampled Y coordinates- The result is implicitly truncated to an integer
- If not specified, defaults to:
0.0
offset_z - Density Function, the offset to apply to sampled Z coordinates- The result is implicitly truncated to an integer
- If not specified, defaults to:
0.0
At least one of offset_x, offset_y, or offset_z must be specified.
Structure Pool Elements#
Added optional corner_constraint Field#
Limits the placement of a structure pool element this by sampling a Density Function at the corners of its bounding box.
Format: list of objects with fields:
density_function - the Density Function to sample at the bounding box' corneracceptable_density - inclusive range of doubles, a corner's sampled density within this range counts as "inside"padding - integer between 0 and 8, the padding of the bounding box before sampling its corners- If not present, defaults to
0
corners - one of all, top, or bottom, which corners to check- If not present, defaults to
all
required_corners - range between 1 and 8, the number of corners that must be inside acceptable_density for the check to pass
- Added
#swimmable for fluids that players can swim in
- Added
#sulfur_cube_archetype/cold - items that can be placed inside the Sulfur Cube that turns it into a Cold Sulfur Cube archetype
- Added
#swimming - entity types that are considered swimming in water - Added
#flying - entity types that are considered flying
Resource Pack Version 101.0#
Block Sprites#
