Snapshot for



Client (.json)

17w50a[1] is the eleventh snapshot released for 1.13, and the final snapshot released in 2017.

Additions[edit | edit source]

  • Added a new local coordinate type in commands using ^.
    • When specifying coordinates in a command, you can now use ^ to specify local coordinates instead of world coordinates.
    • The axes used for local coordinates are relative to the rotation of the executing entity.
    • Like world coordinates, they are measured from the base of an entity.
    • The syntax is: ^left ^up ^forwards
    • left/up/forwards is the amount of blocks in the specified direction.
    • For example, typing /setblock ^ ^ ^3 stone in chat will set a stone block 3 blocks in front of you in your view.
  • Tab-completing coordinates when not targeting a block will suggest ~ ~ ~ again.
  • Added the default tags wooden_buttons and wooden_doors for both items and blocks.
  • The tags buttons and doors now include stone_button and iron_door respectively for both items and blocks.

Changes[edit | edit source]

  • Tags can now include other tags (of the same type).
    • You can add for example #foo:bar in a tag value list to reference another tag called foo:bar.
    • Self referencing is not possible.
  • When overriding a tag, you can now choose to replace instead of append.
    • By default all tags append if another data pack created the tag.
    • Adding "replace": true to your tag definition will make that tag replace existing tags instead.
  • When used in commands, block tags now support block state and data tag arguments.
Item frames
  • Item frames can now be placed on the top and bottom of blocks.
