Minecraft Snapshot 20w46a

The snow is snowier than before.

For today’s snapshot, we’ve changed most of the textures introduced in the previous snapshot. This is simply to test if these textures give a better experience in exploring and building. We’re interested to hear what you think. Keep in mind, that some textures might be reverted or changed again in the future.

New Features in 20w46a

• Added powder snow

Powder Snow

Snowier snow!

• Powder Snow is a trap block that causes any entity that walks into it to sink in it
• You can pick up and place powder snow with a bucket
• Wear leather boots to prevent yourself from sinking into powder snow blocks
• Leave a cauldron outside in falling snow and it will fill with powder snow

Freezing

• Standing in powder snow will slowly freeze an entity
• Once frozen, freeze damage is done every few seconds to the frozen entity
• Each piece of leather armor worn causes an entity to freeze more slowly
• Wearing a full set of leather armor prevents freezing entirely

Changes in 20w46a

• The range in which a lightning rod attracts lightning has been doubled
• Copper blocks are now crafted from four copper ingots
• Sky color now varies smoothly when moving between different biomes
• Buttons that change value (like Difficulty) can now be controlled with mouse wheel
• Clicking on button that changes value while holding shift key changes to previous value
• “Debug” world type can now be accessed while holding alt key (was shift)

Textures

Changed a number of the textures for blocks and items introduced in the previous snapshot:

• Cut copper
• Lightning rod
• Calcite
• Amethyst block
• Budding amethyst block
• Tinted glass
• Candle item icons
• Copper ingot item icon
• Amethyst shard item icon
• Bundle item icon

Technical Changes in 20w46a

• Removed /replaceitem command
• Added /item command
• Added item modifiers, which reuse loot table functions syntax to describe item modification in /item command
• Data pack version is now 7
• Loot tables can now access scoreboard values by UUID
• Loot table values inside random number generators can now be nested
• Default mode of structure blocks is now Load. Data is now hidden (but can be accessed by clicking mode button while holding alt key)

Item modifiers

The function part of loot tables can now be defined as separate data pack resource in item_modifiers directory.
Such files can contain a single function (i.e single JSON object) or an array of functions.

Commands

item

Modifies item or block inventory.

This command has three forms:

• /item <target> replace <item stack> [<count>] - same as old replaceitem
• /item <target> modify <modifier> - modifies item (without copying).
• /item <target> copy <source> [<modifier>] - copies item for source to target(s), optionally applying modifier

Possible sources and targets:

• entity <selector> <slot>
• block <x> <y> <z> <slot>

For example, /item block ~ ~ ~ container.0 copy entity @s enderchest.0 will copy first item from player’s enderchest to first slot of container player is currently standing on.

Loot tables

New conditions

value_check

Checks range of value.

Parameters:

• value - see “New value providers” section (currently combination of random generators and score)
• range - min/max range

Changed conditions

score

entity parameter has now been replaced with target.
It can either contain value from old entity field (like this) or be an score holder name in form {"name": "..."}.

Changed functions

set_damage

This function now has add parameter. If true, change will be relative to current damage. If false, damage will be replaced with current value (default behavior)

set_count

This function now has add parameter. If true, change will be relative to current item count. If false, item count will be replaced with current value (default behavior)

copy_nbt

source parameter can now be set to {"storage": <namespaced id>}, to access command storage.

New functions

set_enchantments

Modifies enchantments on item

Parameters

• enchantments - map of enchantment id to level value (can be score or random number)
• add - if true, change will be relative to current level. If false, level will be replaced with current value (default behavior)

New value providers

Note: value providers can be used in same places as random number generators.

score

Returns scaled scoreboard value.

Parameters

• score - scoreboard name
• target - same as target in score predicate
• scale - scaling factor (float)

Data Packs

Changes to data packs for version 7:

• Removal of /replaceitem (replaced with /item replace)
• score loot table condition: entity parameter has been replaced with target

Resource Packs

Changes to resource packs for version 7:

• Drowned texture mirroring has changed (see MC-174685)
