Nautilus armor

Spawn eggs

  • Added nautilus, zombie nautilus, parched, and camel husk spawn eggs.

Spear

  • New weapon that can be crafted in wood, stone, copper, iron, gold, diamond and netherite versions.
    • Each material has different stats for timing, influencing how fast they are to use.
    • Copper, iron and golden spears can be smelted into the respective nuggets.
  • Cannot be used to mine blocks, as opposed to other weapons.
  • Can be enchanted with the exclusive enchantment Lunge, in addition to the available enchantments for swords (except Sweeping Edge).
  • Has a minimum reach for damage, being too close to a target will yield no damage.
    • Has extended maximum reach compared to other tools and weapons.
  • Zombies, husks, zombified piglins and piglins can spawn holding a spear.
  • Has two attacks: jab and charge.
    • Jab
      • Used by quick-pressing the primary action button.
      • Is a low-damage attack with knockback.
      • Has a cooldown between attacks.
      • Wooden spears have the fastest cooldown, while netherite has the slowest.
      • Can hit multiple enemies.
    • Charge
      • Used by holding the secondary action button.
      • Damage is based on spear material, the player’s view angle, and the velocity of both the player and the target.
      • While holding down the button, the attack goes through three stages before returning to idle:
        • Engaged: The spear can deal damage, knockback, and dismount mounted enemies if the speed is above the required thresholds.
        • Tired: Indicated by the spear rotating to a vertical position and shaking. The Spear can deal damage and knockback (but not dismount) if the speed is above the required thresholds.
        • Disengaged: Indicated by the spear being lowered, pointing downwards. The Spear gives damage but not knockback or dismount if the speed is above the required threshold.
      • The spear's range when used by mobs is half of that when used by players, but they can deal damage, dismount and knockback at lower speeds than the players.
      • Spears provide visual feedback when they hit a target in the charge attack.

Mobs

Camel husk

  • New undead variant of the camel.
  • Spawns at a light level of 0 in deserts.
    • Spawns with two riders: A husk wielding a spear in the front and a parched in the back.

  • Does not burn in sunlight.
  • Has 32HP❤️ × 16 health.
  • Is hostile if the rider is a hostile mob (similar to the zombie horse). Is passive without a rider.
  • Despawns like other hostile mobs, but becomes persistent while ridden by a player.
  • Favorite food is rabbit foot, but it cannot be bred.
  • Drops 2-3 rotten flesh when killed, with an extra 0-1 for each level of Looting.
    • Any husk riding it now has a chance of dropping a rabbit foot on death.
  • As a mount, it works similar to a normal camel.

Nautilus

  • A new neutral aquatic mob.
  • Spawns in all ocean biomes.
  • Has 15HP❤️ × 7.5 health.
  • Attacks using a dash attack, if provoked.
  • Occasionally attacks pufferfish within range using the dash attack.
  • Takes suffocation damage on land.
  • Grants the Breath of the Nautilus effect to mounted players.
  • Can be bred and tamed using a pufferfish or a bucket of pufferfish.
  • A tamed nautilus can be equipped with a saddle, then the player can ride it.
    • While riding it, the player can use its dash attack (similar to camels) by pressing the jump button.
  • Once tamed, has a roaming restriction around its home position of 16 blocks with a saddle, and 32 blocks without.
  • Has a 5% (120) chance of dropping a nautilus shell upon death, on a player kill, unaffected by Looting.

Parched

  • New variant of the skeleton.
  • Spawns at a light level of 0 in deserts replacing some of the regular skeletons.
    • Does not spawn in caves, following the husk's spawning rules.
  • Does not burn in sunlight.

  • Has a coral variant, which appears when spawned in a warm ocean type biome.
  • Hostile only if ridden by a hostile mob.
  • Behaves similar to the nautilus except that it cannot be bred.
  • Burns in sunlight, like other undead mobs.
    • Nautilus armor protects it from sunlight damage.
  • Does not take suffocation damage on land, as opposed to regular nautilus.
  • Drops 0-3 rotten flesh when killed, on a player kill, unaffected by Looting.

Command format

/stopwatch

  • New command that allows the creation of a stopwatch that keeps track of real time.
  • Stopwatches do not depend on game ticks.
  • They only run when the server/world is running, even when paused.
  • Syntax:
    • /stopwatch create <id> - creates a stopwatch with the given namespaced ID.
    • /stopwatch query <id> - returns the queried value and takes in a new scale argument.
      • The returned value will be scaled by that argument and truncated.
      • The scale is optional and will default to 1 if omitted.
      • Example: /stopwatch query foo:bar 20 to get the elapsed time in ticks.
    • /stopwatch restart <id> - restarts the given stopwatch.
    • /stopwatch remove <id> - removes the given stopwatch.

Gameplay

Advancements

    • When doing a jab attack with Lunge, it propels the player horizontally in the view direction.
    • The view angle needs to be perfectly leveled horizontally to achieve maximum lunge distance.
    • Costs saturation/hunger to use, similar to sprinting or jumping.
      • Level I consumes 1 (🍖), level II consumes 2 (🍗), and level III consumes 3 (🍖🍗).
      • Lunge can only be used if the player has at least 6 (🍗🍗🍗) hunger points in their hunger bar.
    • There's also a durability cost of 1 for using Lunge across all Enchantment levels.

    • The animation field has been updated:
      • Renamed spear to trident
      • Added new spear animation.
  • minecraft:intangible
    • Items with this component now show information about it in their tooltip.

Minecraft Server Management Protocol

  • The version is now 2.0.0.

    • Authenticate by passing the token in Sec-WebSocket-Protocol header when opening the WebSocket connection.
      • Example: Sec-WebSocket-Protocol: minecraft-v1, <token>
    • Requests authenticating this way are subject to Origin header checks. This requires configuration of allowed origins on the server side using management-server-allowed-origins. The default value is empty, meaning Sec-Websocket-Protocol authentication is effectively disabled.
  • In the typed_game_rule and untyped_game_rule schemas, the type of the value field has been changed from string to take either a boolean or an integer.
    • It now uses the game rule resource location as the key.

Predicates

  • Component Predicates
    • Component predicates (predicates field in block, item and entity predicates) now include predicates for checking existence of every component type.
    • Those predicates are written as {<component_type>: {}}.
    • Such predicate check passes as long as component is present, no matter the actual value.
    • Existing predicates for specific components remain unchanged.
    • Example:
      • {predicates:{written_book_content:{author:"foo"}} - existing format for matching books.
      • {predicates:{written_book_content:{}} - special case of above that accepted any value, as long as component existed.
      • {predicates:{instrument:{}} - checks if component minecraft:instrument exists (was not allowed before).
  • Entity Predicates
    • The flags predicate now supports new values:
      • is_in_water: when an entity is touching water or a bubble column.
      • is_fall_flying: when an entity is gliding with an elytra.
  • Item Predicates
    • Item predicate in command form (<item>[predicate~{...},component={...}]) has been extended to accept empty predicates for any component type.
    • Similarly to component predicates in data, those empty entries only check for component existence.
    • Existing shorter syntax for checking component existence remains unchanged.
      • That means *[instrument] and *[instrument~{}] are equivalent.

Resource pack

  • The version is now 72.0.
    • This is due to Unifont being updated.
  • block.vsh/fsh copies terrain.vsh/fsh and handles ad-hoc blocks (e.g. held by entities).
  • Added ChunkSection uniform, used by terrain.vsh (which replaces DynamicTransforms).
  • New shaders have been introduced to perform GPU based sprite animations.
  • Globals uniform now has camera coordinates.

Server

      • "Glint Speed"
      • "Glint Strength"

      • "Distortion Effects"
    • Tweaks that were previously hidden behind the "Graphics" setting have been split out to be configurable independently:
      • "See-Through Leaves"
      • "Show Vignette"
      • "Weather Effect Radius"
        • Configures the distance in blocks within which rain and snow are visible.
      • "Improved Transparency"
        • Resolves some of the transparent geometry rendering issues at a significant GPU cost, previously was hidden behind "Fabulous!".
    • A new "Preset" slider was added to the top of the "Quality & Performance" section.
      • Presets control most of the "Quality & Performance" settings at once, not only the ones that were previously hidden behind the "Graphics" setting.
      • Available presets are "Fast", "Fancy", "Fabulous!" and "Custom"
      • The default preset is "Fancy" for new players.
      • But for players who are upgrading to this version the preset will be set to "Custom" to preserve the current configuration.

Shaders & Post-process Effects

  • Added animate_sprite* core shaders, which use a new SpriteAnimationInfo uniform.

Sounds

  • Anvil destroy, land, place and use sounds now play at a slightly lower volume.

Sprite Animations

  • Sprites (textures as part of a larger atlas) are now animated on the GPU rather than per-tick on the CPU.
  • For regular frame-based animations, animate_sprite.vsh and animate_sprite_blit.fsh are used to perform the draw.
  • For interpolated animations, animate_sprite.vsh and animate_sprite_interpolate.fsh are used to perform the draw.
  • The UBO SpriteAnimationInfo contains information on where the sprite should be drawn to, within the greater texture atlas.

Textures

  • All blocks in the world now have mipmaps applied if enabled in video settings.
    • Blocks that did not have mipmaps before, such as different vines, rails, foliage (apart from leaves) and more should look better from higher distances.
  • texture section of *.mcmeta files has a new boolean field darkened_cutout_mipmap
    • The default value is false
    • It is set to true for the block textures that had mipmaps before this version:
    • If the field is set to true and the texture is cutout the mipmaps will be darkened to emulate the darker interior of the block, this was the behavior for cutout mipmapped blocks before this version.
    • Leaving the field unset or setting it to false will generate mipmaps without darkening, and it fits well for other types of cutout blocks that do not have dark interior such as flowers, grasses, vines, rails, etc.
  • Only mipmaps of level 0 and 1 are now animated for block animated textures.
  • Glass and glass panes now support translucent textures.
  • The darkened_cutout_mipmap field of the texture section of *.mcmeta files has been replaced by a new field mipmap_strategy with the following supported values:
    • mean averages both color and alpha between groups of four pixels for the current mipmap level to generate the next mipmap level pixel. This was and stays the default strategy for most solid or translucent full block textures.
    • dark_cutout is similar to mean, but blends colors in a way that makes the pixels bordering cutout pixels darker. This was and stays the strategy for leaves and mangrove roots. It simulates dark interior of the blocks.
    • cutout is a new strategy that always generates a mipmap based on the original texture instead of the previous mipmap. Used for most cutout blocks that became mipmapped in this version.
    • strict_cutout is a modification of cutout that uses stricter alpha cutoff value leading to the textures using this value disappearing at higher mipmap levels. Is used for flowers and similar blocks to avoid artifacts.
    • auto is the default value and will make the game to pick mean for textures that do not contain fully transparent pixels and cutout for those that do.
  • All mipmap levels are once again animated for block animated textures.
  • Beacon and redstone dust now support translucent textures.

UI

  • Menu sliders will now "stick" to the closest available value when releasing them after dragging with a mouse.
  • When using keyboard to change slider values, arrow keys will now move the slider to the next available value, not by one pixel as before.
  • The inF3 button in the Debug Option screen has been renamed to inOverlay.
  • "Interface" option inside the Video Settings screen has been renamed to "Preferences".
  • The Single Biome Customization screen now has a search box.
  • The language selection screen now has a search box to filter languages.

  • Added new UI sprite:
    • container/slot/nautilus_armor
    • container/slot/spear
  • Added new nine-sliced sprites:
    • container/inventory/effect_background
    • container/inventory/effect_background_ambient
