Java Edition 18w45a

18w45a is the fifth snapshot for Java Edition 1.14, released on November 7, 2018^[1], which adds scaffolding and illager patrols.

Scaffolding

• A new climbable block that can be crafted using bamboo and string.
• The player can climb up a block by jumping and go down by pressing sneak.
  • The player can sneak by pressing sneak when there's no other scaffolding block below.

Illager banner

• Spawns on some illager patrols.

Illager patrols

• Spawn in the world as a pack of 5 mobs consisting of an illager beast and 4 pillagers or vindicators.
• Spawn in all variations of the plains, taiga, desert and savanna biomes, on top of grass or sand blocks.
• A new banner can be found on the patrol leader's head.

Resource packs

• Added "Programmer Art – The classic look of Minecraft" to the resource pack menu.

/loot

• General syntax: /loot <target> <source>.
• Sources:
  • fish <loot table id> <fishing location> [tool <item>|mainhand|offhand]
    • Uses fishing context.
  • loot <loot table id>
    • Uses loot chest context (can be also used for advancement awards and cat gifts).
  • kill <entity selector>
    • Simulates entity drops.
  • mine <mining location> [tool <item>|mainhand|offhand]
    • Simulates block drops.
• Targets:
  • spawn <position>
    • Drops in world.
  • replace
    • Works similar to /replaceitem. If count is missing, command tries to place all returned items. If count is higher than number of items, remaining slots are cleared.
  • entity <entity selector> <start slot> [<count>]
    • Replaces a range of slots.
  • block <position> <start slot> [<count>]
    • Replaces range of slots.
  • give <player selector>
    • Inserts items into player's inventory (similar to /give).
  • insert <position>
    • Inserts items into container (similar to ⇧ Shift+left-click).

Signs

• Rewrote the sign editing to be more intuitive.
• New movable cursor for free text editing.
• Selection support.
• Copy and paste.

Ladders and Vines

• Can now also be climbed using the jump key.

/drop

• Renamed to /loot and reworked the syntax to be easier to understand.

Advancement predicates

• Entity predicate now accepts equipment field.
  • This predicate can contain up to six fields: head, chest, legs, feet, mainhand, offhand.
  • If this predicate is non-null, test fails for entities that have no equipment (i.e. not mobs, players or armor stands).
