Minecraft:Java Edition 17w43a

17w43a is the first Minecraft:snapshot for Minecraft:Java Edition 1.13, released on October 25, 2017,<ref>Template:Snap</ref> adding the first features of what was then called "Technically Updated". Although this is the first snapshot of 1.13, no Update Aquatic features were implemented yet because at the time the Update Aquatic was set to be released as 1.14 instead of 1.13, and as such snapshots from 17w43a to Minecraft:18w06a mainly add or modify commands.

Additions

General

Minecraft:Data packs

• Like Minecraft:resource packs, but for Minecraft:loot tables, Minecraft:advancements, functions, and Minecraft:structures.
  • Used by placing them into the datapacks folder of a world.
• Data packs are .zip files or folders with a pack.mcmeta in the root. See Tutorial:Creating a resource pack for more info.
• Structures will load from (world)/generated/structures/(namespace)/(file).nbt before checking data packs.
  • However, this directory should not be used to distribute structures. Instead, move these files into data packs.
• Reloadable using Template:Cmd.
• Structure: pack.mcmeta, data folder containing a namespace folder determining the namespace of its contents.
  • A namespace should only contain the following symbols: Template:Code.
  • Inside the namespace folder, there can be folders for functions, loot_tables, advancements and structures.

Minecraft:Options

• Fullscreen resolution
  • Is used to change the resolution when in fullscreen.
