[[Particles (Java Edition)|Particles]] * Added gust, gust_dust and trial_spawner_detection particle types. == Changes == === Blocks === ; [[Jigsaw block]] * Increased maximum value of structure variable size from 7 to 20. ; [[Monster spawner]] * Now renders their inner faces when looking inside. === General === ; [[Data pack]] * The version is now 24. ; [[Processor list]] * Added trial_chambers_copper_bulb_degradation. ; [[Resource pack]] * The version is now 21. * uniform font has been updated to use Unifont 15.1.04 (from 15.0.06). ** During the updates of Unifont, glyphs of CJK unified ideographs in [[wikipedia:CJK Unified Ideographs Extension I|CJK Unified Ideographs Extension I]] were added.[http://unifoundry.com/unifont/index.html GNU Unifont Glyphs - Unifoundry.com], [https://web.archive.org/web/20240124012215/https://unifoundry.com/unifont/index.html Archive on Wayback Machine] * The only supported texture format is now .png. == Experimental == These additions and changes only take effect when the [[Update 1.21]] experimental data pack is enabled. === Additions === ==== Blocks ==== ; [[File:Trial Spawner JE1 BE1.png|32px]] [[Trial spawner]] * A block similar to [[monster spawner]]s that ejects rewards upon completion and can have variable levels of challenge in multiplayer. * The challenge level increases for each new player a trial spawner notices nearby. ** Challenge level doesn't decrease until it is reset during a trial spawner's cooldown. * Unlike normal spawners, a trial spawner spawns a limited number of mobs proportional to its current challenge level. ** It can only spawn a mob at positions that are within line of sight. ** It can spawn a mob regardless of any light level requirement the mob has. ** Spawned mobs are persistent and don't despawn. * Once all mobs are defeated, the trial spawner ejects a set of rewards proportional to the current challenge level. ** After the rewards have been ejected, the trial spawner goes into cooldown for 30 minutes during which it no longer spawns mobs. * Can't be crafted nor obtained by players in Survival - instead, they can be found naturally placed throughout [[trial chambers]]. * Extremely slow to mine and resistant to explosions, and don't drop even with [[Silk Touch]]. * When placed in Creative, trial spawners have no mob type set by default. ** The mob type can be set by interacting with it while holding a spawn egg. * Creative and Spectator players cannot be detected or noticed by trial spawners. ==== Items ==== ; [[Spawn egg]]s * [[File:Breeze Spawn Egg JE1 BE1.png|32px]] [[Breeze]] spawn egg ; [[File:Trial Key JE1 BE1.png|32px]] [[Trial key]] * An item that can only be obtained from trial spawners. * Currently doesn't have any functionality. ==== Mobs ==== ; [[File:Breeze JE1.png|32px]] [[Breeze]] * The breeze is a cunning, hostile mob that can spawn via trial spawner in some rooms within the trial chambers. * Has {{hp|30}} health points. * Cannot be hit by [[arrow]]s or [[trident]]s. * The breeze moves primarily by leaping around the target, sometimes jumping quite long distances. * An aggressive adversary, the breeze shoots volatile wind energy in the form of wind charge projectiles at its target. * Wind charges deal a small amount of damage when colliding directly with an entity. * After colliding with an entity or a block, wind charge projectiles produce a wind burst, which knocks back entities in the area by several blocks. * Wind bursts also have the effect of 'activating' certain blocks: ** Non-iron doors and trapdoors are flipped. ** Fence gates are flipped. ** Buttons are pressed. ** Levers are flipped. ** Bells are rung and swung. ** Lit candles (both standalone and on cake) are extinguished. * Wind bursts do not have any effect on iron doors, iron trapdoors, or any block being held in its position by a redstone signal. * Currently does not drop any loot. ==== Non-mob entities ==== ; [[File:Wind Charge JE1 BE1.png|32px]] [[Wind charge]] * Fired by the [[breeze]]. * Explodes upon impact, emitting a large burst of plume particles and [[Knockback (mechanic)|knocking]] entities back similar to a TNT explosion. * Its explosion interacts with certain blocks, including [[button]]s and [[trapdoor]]s. * Deals damage when colliding directly with a player or mob. * Can be deflected, just like [[fireball]]s. ==== World generation ==== ; {{EnvLink|Trial chambers}} * A new structure in the Overworld where players can explore and take on combat challenges during the mid-game. ** Made out of a variety of copper and tuff blocks and can be found in different sizes from large to small. ** Relatively common throughout the deepslate layer of the underground, with the starting piece generating at a height between -40 and -20. * The layout of each trial chamber is procedurally generated, and can include traps, supply and reward chests, decorated pots, and a variety of combat spaces. ** Traps include dispensers containing different potential items, such as [[arrow]]s or [[fire charge]]s. ** Supply chests can be found between the different rooms, and give the player blocks and items which help them navigate their trials. ** Reward chests are guarded by challenges in each room, and can be a source of many high level enchanted books and equipment. ** Decorated pots found in hallways can contain supplies such as iron or arrows. Some pots are decorated and others are blank. ** The loot found in reward chests and decorated pots are still being iterated, and are absolutely not final as well as the loot from defeating mobs from a trial spawner. * Each trial chamber can include trial spawners from three categories: ** Melee: zombie, husk or slime. ** Small melee: spider, cave spider, baby zombie or silverfish. ** Ranged: skeleton, stray, or skeleton with arrows of Poison. * Each trial spawner category only uses one mob for the entire structure when generated, and these mobs are randomized for each trial chamber. ** For example, one trial chamber might only spawn zombies, cave spiders and strays, while another might only spawn slimes, silverfish and skeletons. ** The exceptions to this are some trial spawners in unique rooms which always spawn breezes. * Regular mob spawning does not happen inside the bounding boxes of the trial chamber pieces. ==== General ==== ; [[Tag]]s * Added following damage type tag: ** #breeze_immune_to: contains arrow and trident. * Added following entity type tags: ** #deflects_arrows: contains breeze. ** #deflects_tridents: contains breeze. * Added following biome tag: ** #has_structure/trial_chambers: contains #is_overworld. === Changes === ==== Blocks ==== ; [[Copper grate]]s * Now prevent mob spawning on top of them. * No longer suffocate mobs who end up with their head inside them. ==== General ==== ; [[Resource pack]] * Added entity models and textures for experimental breeze mob: ** breeze, wind_charge. * Added shader: ** breeze_wind. ; [[Tag]]s * Added breeze into #fall_damage_immune entity type tag. == Trivia == * This snapshot is one of the only two snapshots for ''Minecraft Java Edition'' to have its digits consecutively increasing by one. The only other snapshot to have this property is [[12w34a]]. == Fixes == {{fixes|fixedin=23w45a |;From released versions before 1.20 |131646|Drowned spawners only work in biomes where drowned spawn. |136904|{{cmd|execute store score}} does not store 0 when subcommand is advancement and fails. |169969|The back faces of spawners do not render. |177446|RootVehicle tag in playerdata entry is not upgraded. |186797|Functioning clock and compasses in crafting output slot. |255244|NBT link/reference when using {{cmd|fill}}. |;From 1.20.2 |266256|Accessibility button in the Welcome screen still needs its own string. |;dev |265702|Text components in commands accept malformed JSON. |265747|Punching a TNT Minecart in creative mode drops the minecart. |265875|Compasses, Clocks and Recovery Compasses work normally within the output slot of the crafter. |266054|Side Water texture on Copper bulbs. |266056|Mobs suffocate inside most copper grate block variants. |266063|Copper Doors and Trapdoors make generic metal sounds when placing. |266090|Light can pass through copper bulbs. |266091|Copper Bulbs do not cull faces correctly. |266096|Mobs can spawn on oxidized or waxed copper grates. |266248|No error message when granting/revoking an advancement that is already granted/revoked. |;previous |266287|Can't load {{cd|d=and|.dat|.nbt}} (server list & saved hotbar). |266289|Could not save data {{cd|d=and|raids.dat|random_sequences.dat}}. }} == Video == {{slicedlime|2eBDYjCO-pY}} == References == {{Reflist}} == Navigation == {{Navbox Java Edition versions|1.2x}} [[de:23w45a]] [[es:Java Edition 23w45a]] [[fr:Édition Java 23w45a]] [[ja:Java Edition 23w45a]] [[lzh:二三週四五甲]] [[pt:Edição Java 23w45a]] [[ru:23w45a (Java Edition)]] [[uk:23w45a (Java Edition)]] [[zh:23w45a]]
