More Nether Tweaks Incoming - Snapshot 20w17a is out!

Posted: 22 Apr 2020 07:12 AM PDT

This week's snapshot brings you some tweaks, bugfixes, and technical changes!

This update can also be found on minecraft.net.

We also have a survey up so that you can tell us what you think about the Nether Update. You can find it by clicking here. We would very much appreciate if you could take the time and fill it out.

If you find any bugs, please report them on the official Minecraft Issue Tracker.

New Features in 20w17a

Added an Entity Distance scale option ranging from 50% to 500%
Difficulty and game rules can now be changed from "Create World" screen

Changes in 20w17a

Improved Smithing Table UI
Ruined portals now spawn less frequently
Renamed "Soul Fire Torch" and "Soul Fire Lantern" to "Soul Torch" and "Soul Lantern"
Tweaked Bastion Remnant loot
Walls now create posts under more things, like pressure plates and banners
The "Singleplayer" button will jump directly to "Create World" screen if there are no worlds to select

Technical Changes in 20w17a

Block storage format in chunks slightly changed to speed up various tasks (rendering, pathfinding, world generation, etc).
Chat component style can now select font.
Full range of Unicode characters is supported (some may know what that means 😉)
Added the attribute command

World save format

Saving level.dat now uses randomly-named temporary files (instead of using level.dat_new every time)
player/*.dat are now saved in a way similar to level.dat (including leaving .dat_old files)

Block storage

BlockStates in Sections elements no longer contain values stretching over multiple 64-bit fields. If number of bits per block is not power of two (i.e. single 64-bit value can't fill whole number of blockstates) some bits will not be used. For example, if single block state takes 5 bits, highest 4 bits of every 64-bit field will be unused. That also means slight increase in storage size (in case of 5 bits, from 320 to 342 64-bit fields).

Commands

`attribute`

Adds modifies attribute on single entity. Possible syntax: Parameters:

attribute <target> <attribute> get [<scale>] - get total value of attribute
attribute <target> <attribute> base set <value> - sets base valye
attribute <target> <attribute> base get [<scale>] - get base value
attribute <target> <attribute> modifier add <uuid> <name> <value> add|multiply|multiply_base - adds modifier (fails if modifier is already present)
attribute <target> <attribute> modifier remove <uuid> - removes modifier
attribute <target> <attribute> modifier value get <uuid> [<scale>] - get value of modifier
target - single entity (note: only players, armor stands and mobs have attributes)
attribute - name of attribute (like minecraft:generic.max_health)
name - string (in optional quotes) describing human-readable name of modifier
value - floating point value (note: certain attributes have limits on final value, so your change might not be noticeable)

Chat components

Hover event argument

style.hoverEvent parameter now has parameter contents, with contents depending on type:
- For show_text - chat component
- For show_item - either item id or object with fields id, count and tag (with last one being serialized NBT)
- For show_entity - object with fields: id (UUID), name (chat component) and type (entity type resource location)
Old style value argument is now deprecated (but still supported)

Colors

color property can now contain RGB value prefixed by #. For example #55ff55 will result in the same color as green.

Custom fonts

Chat component style now supports font property, which is resource location for font in resource pack. No entry is equivalent to minecraft:default.

Fonts

Force Unicode option now switches between normal and alternative font (called uniform.json) - no reload needed
