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 warn causes an entity to freeze more slowly
Wearing a full set of leather armor prevents freezing entirely

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)

Changes to data packs for version 7:

Removal of /replaceitem (replaced with /item replace)
