Minecraft Snapshot 23w42a

Hey! Today we bring you the first of the features we've shown you during Minecraft Live last weekend: the Crafter!

Experimental Features

Crafter

• The Crafter is a new block that enables the crafting of items and blocks via Redstone
• The Crafter will eject one crafted item at a time when powered by a new Redstone signal / pulse (not a continuous signal)
• Upon receiving this new signal, the Crafter will eject the recipe result from the front face
• If the output result has multiple type of items all the result items will be ejected together
• The Crafter can be oriented in any direction when placed

Crafter UI

• The Crafter has a 3x3 interactable crafting grid
• The Crafter’s crafting grid slots are toggleable, meaning that the player can change the behavior of a slot by clicking or pressing on a slot with an empty hand
• A slot that is ‘toggled’ cannot hold any items, and therefore cannot have items placed into it by other blocks, such as Hoppers and Droppers
• Unlike the Crafting Table, the Crafter displays a preview of the crafted item which will be crafted and ejected on the next Redstone pulse but cannot be manually taken out by the player
• The Crafter UI is shared between all players interacting with the Crafter, meaning that multiple players can interact with the Crafter at the same time, similar to Chests and Hoppers

Crafter interaction with other blocks

• The Comparator signal strength is 0-9, where each non-empty or toggled slot adds 1 strength
• Hoppers can be used to both insert and pull out items from the Crafter
• Droppers can be used to insert items into the Crafter
• Moving items in from another block (ex: Hopper, Dropper) prioritizes filling items into slots following these rules:
  • Prioritize the first empty slot (from left-to-right, top-to-bottom)
  • If there are no empty slots then prioritize the smallest stack of the same item (pick the first if there are multiple)
  • If there is a toggled slot it will be skipped. The item will then be moved into the container
  • If the item cannot be moved, it will be ejected into the world

We want to hear your feedback on the Crafter, so please let us know what you think the over in our dedicated feedback thread.

Jigsaw pool aliases

• Added optional pool_aliases list to Jigsaw structures
• Aliases represent the possibility to rewire Jigsaw pool connections by redirecting pool references on individual structure instances
• Alias variants are represented in type and is one of:
  • direct 1:1 mapping from an alias to a new pool
    • alias pool to replace
    • target pool to replace with
  • random 1:n mapping where a pool from n is randomly selected for the structure instance
    • alias pool to replace
    • targets randomized list of candidate pools to replace alias with
  • random_group
    • groups each group is a randomized list of above alias types
    • only one group is selected per structure instance
    • this enables modelling selections such as "if pool X is replaced with X1, also replace pool Y with Y1"

Resource Pack Version 19

• Added block model, item model and block state definitions for crafter
• Added GUI container texture and sprites for crafter
• Added white_smoke particle definition
