Defaults to 80. * Added playersNetherPortalCreativeDelay to control time (in game ticks) that a player needs to stand in a nether portal before changing dimensions, while in Creative mode. Defaults to 1. * Added projectilesCanBreakBlocks, to control whether impact projectiles destroy blocks that are destructible by them (i.e. [[chorus flower]]s and [[decorated pot]]s), and to control whether [[trident]]s destroys [[pointed dripstone]]s. Defaults to true. ; [[Loading screen]] * Added a new screen for handling corrupted level files. ** It gives the player the option to restore a backup, and a quick link to the bug tracker for reporting a bug about it. ; [[Options]] * Added "Hide Splash Texts" in accessibility options, which allows the [[splash]] in the main menu to be hidden. ; [[options.txt]] * Added hideSplashTexts, defaults to false. ; [[Particles]] * Added new white_smoke particle type. == Changes == === Blocks === ; [[Decorated pot]] * Now appears in the "Redstone" tab of the Creative inventory. === General === ; [[Custom structure]] * Changes to structure type definitions (data/minecraft/worldgen/structure): ** 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". ; [[Data pack]] * The version is now 21. * Added white_smoke particle definition. * Renamed field {{nbt|short|Fuse}} to {{nbt|short|fuse}} on [[TNT]] entity. ; [[Entity format]] * In NBT format for entity type tnt: ** Added block_state. *** This field allows replacement of rendered block model. ** Renamed Fuse to fuse. ; [[Raw JSON text format]] * Changes to chat component serialization: ** Components of type nbt now have source field with allowed values: {{cd|d=and|entity|block|storage}}. ; [[Resource pack]] * The version is now 19. * Added block model, item model and block state definitions for crafter. * Added GUI container texture and sprites for crafter. ; [[Tag]] * Added firework_rocket into the impact_projectiles entity tag. == Experimental == These additions and changes only take effect when the [[Update 1.21]] experimental data pack is enabled. === Additions === ==== Blocks ==== ; [[File:Crafter JE1.png|32px]] [[File:Crafter Triggered JE1.png|32px]] [[File:Crafter Crafting JE1.png|32px]] [[Crafter]]s * Can be crafted with five [[iron ingot]]s, a [[crafting table]], two [[redstone dust]]s, and a [[dropper]] in the crafting table. * Can be oriented in any direction when placed. * A [[pickaxe]] can increase the speed of mining them. * Have a user interface similar to crafting table. ** Have 3×3 interactable crafting grid. ** Their 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 toggled slot cannot hold any items and therefore cannot have items placed into it by other blocks such as [[hopper]]s and [[dropper]]s. *** A toggled slot can be toggled off by player, whether clicked directly or holding item(s), pressing slot keys associated with an empty or a not empty hotbar slot. ** Unlike the crafting table, the slots display 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 user interface is shared between all players interacting with them, meaning that multiple players can interact with them at the same time, similar to [[chest]]s and hoppers. ** The user interface does not have a [[recipe book]] to provide help, so the player must know the recipes. * The crafter ejects one crafted item at a time when powered by a new redstone pulse, a redstone signal that is not a continuous signal. ** Upon receiving this new signal, crafters eject the recipe result from the front face. ** All the result items are ejected together when the output result has multiple type of items. * They can interact with hoppers and droppers, to input/output automatically. ** Hoppers can be used to both insert and pull items out of them. ** Droppers can be used to insert items into them. ** Moving items in from another block with a hopper or a dropper prioritizes filling items into slots, by following these rules: *** If there is a toggled slot, skipped. *** If there is not a toggled slot, crafters prioritize the first empty slot from left-to-right and top-to-bottom. *** If there is not a toggled slot, and there are no empty slots, crafters prioritize the smallest stack of the same item. If there are multiple possible stacks, pick the first from left-to-right and top-to-bottom. ** If failed to select a slot, hoppers and droppers don't take any action. * When read by a [[redstone comparator]], the redstone signal strength is 0 to 9, where each non-empty or toggled slot adds 1 strength. === Changes === ==== General ==== ; [[Tag]] * Added crafter into mineable/pickaxe and needs_stone_tool block tags. == Fixes == {{fixes|fixedin=23w42a |;From released versions before 1.20 |5820|The game doesn't recognise the ISO 8601 date format. |189261|Various Realms buttons and texts are incorrectly capitalized. |223774|Firework Rockets can't be used to break Chorus Flowers. |225364|Chorus flowers can be destroyed by projectiles in adventure mode. |225365|Pointed dripstone can be destroyed by tridents in adventure mode. |232719|The scroll bar within the singleplayer menu doesn't reset its position to the top of the list when searching for worlds. |234483|Some strange pixels can be seen on the left side of world slot frames within several Realms menus. |237009|Incompatible worlds don't have a tooltip in the world list. |;From 1.20 |262888|Clicking "I know what I'm doing!" on the world loading screen when loading a world in a new snapshot is way too loud. |;From 1.20.2 |264966|Signature is missing from Property textures appears in the logs of some Minecraft worlds due to player heads. |265515|The "You don't seem to have a Realm" element in the realms menu cannot be selected via the mouse cursor. |265517|The "Buy a realm!" button is automatically selected when opening the "Add Realm" interface. |265551|"No pending invites!" tooltip in Realms is now untranslatable. |;previous |265744|Kick during login causes client error. |265745|You can’t break decorated pots with fireworks launched from crossbow. |265751|Decorated pot subtitles are inconsistent. |265758|Decorated pots can be destroyed by projectiles in adventure mode. |265761|Decorated pots are missing from the creative inventory's redstone blocks tab. |265767|Commands don't show error messages in chat. |265773|Functions executed as advancement rewards are executed at the top level. |265778|{{cmd|gamerule maxCommandChainLength 0}} prevents subsequent command execution in the world. |265789|Realms popup strings consist of inconsistent concluding punctuation. }} == Video == {{Slicedlime|d2D-CDsOQvo|nJXFKPm0b-k}} == References == {{Reflist}} == Navigation == {{Navbox Java Edition versions|1.2x}} [[de:23w42a]] [[es:Java Edition 23w42a]] [[fr:Édition Java 23w42a]] [[ja:Java Edition 23w42a]] [[lzh:二三週四二甲]] [[pt:Edição Java 23w42a]] [[ru:23w42a (Java Edition)]] [[uk:23w42a (Java Edition)]] [[zh:23w42a]]
