Minecraft snapshot 23w42a patch notes

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

Changes

Players now have a new recovery screen to repair their worlds in case of missing data:

• Added an accessibility option that allows to hide the yellow splash texts in the main menu
• Added a recovery screen for worlds with missing data (for example, if saving failed due to an unexpected shutdown)

Fixed bugs in Minecraft snapshot 23w42a

• Various Realms buttons and texts are incorrectly capitalized
• Firework Rockets can't be used to break Chorus Flowers
• The scroll bar within the singleplayer menu doesn't reset its position to the top of the list when searching for worlds
• Some strange pixels can be seen on the left side of world slot frames within several realms menus
• Clicking "I know what I'm doing!" on the world loading screen when loading a world in a new snapshot is way too loud
• "Signature is missing from Property textures" appears in the logs of some Minecraft worlds due to player heads
• The "You don't seem to have a Realm" element in the realms menu cannot be selected via the mouse cursor
• The "Buy a realm!" button is automatically selected when opening the "Add Realm" interface
• "No pending invites!" tooltip in Realms is now untranslatable
• Kick during login causes client error
• You can’t break decorated pots with fireworks launched from crossbow
• Decorated pot subtitles are inconsistent
• Decorated pots can be destroyed by projectiles in adventure mode
• Decorated pots are missing from the creative inventory's redstone blocks tab
• Commands don't show error messages in chat
• Functions executed as advancement rewards are executed at the top level
• "gamerule maxCommandChainLength 0" prevents subsequent command execution in the world
• Realms popup strings consist of inconsistent concluding punctuation
