It has access to: ** Player as this entity. ** Position of the placed/interacted block. ** Block state of the placed/interacted block. ** Held/used item as "tool". * Migration guide: ** Contents of old location field should be migrated to a location_check condition. ** Contents of item field should be migrated to a match_tool condition. ** Contents of block and state fields should be migrated to a block_state_property condition. * Advancement fields now have a new boolean field called sends_telemetry_event. ; [[Data pack]]s * Version is now 15, accounting for predicate/loot table and advancement changes. ; [[Creative inventory]] * [[Jukebox]] has been added to the "Redstone Blocks" tab. ; [[Predicate]]s * Condition alternative has been renamed to any_of. * Added new condition all_of that passes only when all sub-conditions pass. ** It has the same syntax as any_of. ; [[Sound]]s * Walking on a block now always plays a step sound. ** It was previously not the case if the player was walking along the edge of a block with air or fluid beside it. * Walking on the ocean floor produces a step sound for the block the player is walking on, but at a lower volume and pitch. ; [[Telemetry]] * Added new property: launcher_name. ** A new global property sent with every event. ** This is set based on the minecraft.launcher.brand system property. ** This helps developers troubleshoot game launch related bugs more effectively, as they are able to see whether the issue originated in the Minecraft launcher or a third-party program. * Added new property realms_map_content to event world_loaded. ** When loading into a Realms Map Content world (Minigame), the world_loaded event receives the name of that map. ** This is to help developers understand how Java Realms users interact with Java Realms adventure or minimap content. * Added new optional event advancement_made. ** This event is triggered when a player completes an advancement. ** This allows developers to see the advancement ID and the time when the advancement was completed, and helps them as a studio understand player progress and limits, which informs their game design. * Added new optional event game_load_times. ** An event that is triggered when the game client is loaded, and includes the time it took for the client to load. ** This is so that developers can work on improving and reducing the time it takes to load the game client. == Fixes == {{fixes|fixedin=23w18a |;old |1133|Whether or not a player experiences some effect is calculated based on the block under the center of the player. |2604|Walking on non-solid blocks with no collision plays their respective walking sounds. |48923|Slime/magma cubes not affected by jump boost potion effect. |75721|Arrow buttons within the book GUI are rendered above tooltips. |130089|Turtle eggs break weird at block edges. |158154|Players can bounce on beds even when not directly touching it. |199952|Skylight does not propagate across certain chunk borders upon world generation. |203317|There is a missing torch in one of the Stronghold rooms leaving a Light source. |207290|Sculk sensors don't detect vibrations while walking on the edge of a block. |212583|Sculk sensors are not activated upon walking inside of scaffolding that has air below it. |217447|"Walking" on nether wart produces stone footstep sounds instead of nether wart sounds. |240098|Minecraft can't be correctly profiled to Windows 11 version. |242105|When landing on some non-full blocks while touching a thin block, impact particles use the thin block's texture. |244307|Dark Chunks when exploring since 1.18. |252389|When landing (or jumping) on wool with your hitbox over the edge, it produces a vibration. |257269|Sculk sensor detects player walking between carpet and wool. |259978|Minecraft telemetry data detected Windows 11 as Windows 10. |260279|Jukebox is not in the Redstone Blocks tab in the creative inventory. |261417|The hitboxes of sniffers are not adjusted when they lay down. |262067|The type of sniffer digging particles that are produced is determined by the block that sniffers are located on instead of the block that sniffers are digging. |262069|Sniffers continue digging after their target block is destroyed. |;dev |261952|Clocks flicker rapidly when enchanted and in an unnatural dimension. |262003|Bundle tooltip does not show its interface. |262104|Rendering of FPS graph seems to be performing worse than before. |;previous |262123|Advancement titles of new advancements are improperly capitalized. |262185|Partially transparent pixels in font glyphs appear more opaque than they should in the tooltip. |262133|Strong lag spikes when moving above a cleared area with exposed void. |262218|Block light updates don't cross chunk borders properly in 23w17a. }} == Video == {{Slicedlime|DkALpstYcKw}} == References == {{Reflist}} == Navigation == {{Navbox Java Edition versions|1.2x}} [[de:23w18a]] [[es:Java Edition 23w18a]] [[fr:Édition Java 23w18a]] [[ja:Java Edition 23w18a]] [[lzh:二三週一八甲]] [[pt:Edição Java 23w18a]] [[ru:23w18a (Java Edition)]] [[uk:23w18a (Java Edition)]] [[zh:23w18a]]
