Fixed bugs in 1.21.2

We're now releasing the Bundles of Bravery game drop for Java Edition, featuring space-saving Bundles and the addition of Hardcore Mode to Realms!

This game drop is all about embarking on a new adventure, collecting everything you can along the way, and definitely not dying. Together with these additions, we've also added baby variants of Dolphins and Squids, given Redstone Torches an updated look, optimized the game, and fixed over 300 bugs! To top it off, there's also a heap of technical changes, bringing even more control to creators.

Goodness, that was a lot, wasn't it? Perhaps we should've stuffed it all into a Bundle?

New Features

  • Added Bundles

An assortment of differently dyed bundles laying on the grass in a forest.

Bundles

  • A Bundle is an item that can pack different items together into the same stack
  • A Bundle only fits one stack (usually 64 items) but it can be a mixture of many different item types
  • You can insert items into a Bundle directly in the inventory
  • Bundles have a tooltip that shows the items inside
    • If a Bundle has less than 12 item types inside, the tooltip will show all of them
    • Otherwise, the tooltip will show the top three rows of items (at least 8 item types) and the others will be hidden below
  • You can select any of the visible items to pull out of the Bundle
    • Right-click to take the first item
    • Use the scroll wheel to select a different item, then right-click to take it
  • When selecting an item to remove, the Bundle icon shows that item poking out of the Bundle
  • When holding a Bundle in hand, you can empty items onto the ground by right-clicking or holding right-click
  • The Bundle is crafted with one String above one Leather
  • The controls have changed from the original prototype:
    • Use left-click to put an item into a Bundle
    • Use right-click to remove the top item type from a Bundle
    • When the Bundle tooltip is visible, use the mouse wheel to select a different item type, then use right-click to remove it

Alex is standing on the porch of a cobblestone house reaching out their arms with a pink dyed bundle in their hand, offering it to Ari that is standing opposite them on the gravel road outside the house.

Tweaks to Blocks, Items and Entities

  • Salmon may now spawn as Small, Medium (current size), or Large

From under the water, looking up towards the sky through a ravine we can see baby glow squids and baby dolphins swimming around.

Ender Pearl Chunk Loading

  • Ender Pearls now ensure that the chunk they are in or travel into is always loaded and ticking
    • They also load chunks when crossing to a new dimension
    • This ensures that Ender Pearls can always land, and makes cross-dimensional Ender Pearl travelling more predictable
  • Ender Pearls now unload when a player logs out, and reappear whenever that player logs back in, similar to how ridden entities currently behave

A stream of Ender Pearls flying between two nether portals in a crimson forest in the nether.

    • The previous textures have been added to Programmer Art resource pack
  • Tweaked air bubbles UI
    • Added an empty state for air bubbles along with a wobble when the player is drowning
    • Added a popping sound when the bubbles pop in the UI

Rarity

  • Rarity is a set of categories which determine the color used to display the name of an item or block
    • It has no gameplay impact, but is used to signal how difficult something is to obtain
    • By default, unless specified otherwise, all items and blocks have a rarity of Common which displays their name in the color white
  • We have re-evaluated the rarity of all items and blocks in the game to more accurately reflect the current challenge of obtaining them, given the following guidelines:
    • Items and blocks become more rare depending on the following factors:
      • The chance of finding it in a loot table, including mob drops
      • The amount of travelling required to obtain it
      • The difficulty of any obstacle which must be overcome to obtain it
      • The possible amount of that item or block which exists in the world
    • Any item or block which can be crafted must inherit the highest rarity of its crafting ingredients
      • For example, a Mace has an Epic rarity because one of its ingredients (the Heavy Core) has an Epic rarity
      • Likewise, any crafted item which has only Common crafting ingredients must also be Common
  • The lists below detail the items and blocks which have changed to that rarity category

  • The nine_slice GUI sprite scaling mode has a new optional boolean property: stretch_inner
    • If true, the inner parts of the texture (i.e. not the corners) will be stretched instead of tiled
    • If not specified, defaults to false as before
  • The tooltip background and frame may now be customized by replacing sprites:
    • tooltip/background: The background of the tooltip
    • tooltip/frame: The frame appearing around the tooltip
    • Items with a custom tooltip_style component will use sprites with IDs:
      • <namespace>:tooltip/<path>_background and <namespace>:tooltip/<path>_frame
  • The appearance of a highlighted slot may now be customized by replacing sprites:
    • container/slot_highlight_front: The sprite to render in front of highlighted slots
    • container/slot_highlight_back: The sprite to render behind highlighted slots
  • Likewise, the appearance of a highlighted item within the Bundle can be customized with the following sprites:
    • container/bundle/slot_highlight_front

  • If specified and non-zero, this will behave as the minimum light level that the element can receive

Item Models

  • All item models can now use the broken property in model overrides that was previously limited to just Elytra
    • This will have a value of 1 if the item has 1 durability left, or 0 otherwise

Custom Equipment Layers

The appearance of equipment when equipped by players or certain mobs can now be customized by defining 'equipment models' in the Resource Pack.

  • Equipment model definitions are loaded from assets/<namespace>/models/equipment/<path>.json
    • These can then be referenced by the equippable component with a model id of namespace:path
  • The model definition is an object with fields: wolf_body, horse_body, llama_body, humanoid, humanoid_leggings, wings
    • All fields are optional, and can be used to specify a list of layers for the given model layer type
    • Each field contains list of layer objects:
      • texture: namespaced texture location for this layer
        • namespace:path will resolve to assets/<namespace>/textures/entity/equipment/<layer_type>/<path>.png
      • dyeable: object with fields (optional), specifying how this layer behaves when dyed (in the dyeable item tag, and has dyed_color component)
        • color_when_undyed: rgb color int (optional)
        • If specified, this layer will be tinted by the color contained in the dyed_color component
          • If the item is not dyeable or not dyed, it will be tinted based on the color specified by color_when_undyed
          • If color_when_undyed is not specified and the item is not dyed, the layer will be hidden
      • use_player_texture: boolean (default: false), true if this layer texture should be overridden by a texture given by the player
        • Only used for wings layers, which will override with the player's custom Elytra texture

A model definition specifying both player and horse armor layers might look like:

{
  "layers": {
    "horse_body": [
      { "texture": "minecraft:iron" }
    ],
    "humanoid": [
      { "texture": "minecraft:iron" }
    ],
    "humanoid_leggings": [
      { "texture": "minecraft:iron" }
    ]
  }
}

Trims

  • All equippable items with an equipment model defined support rendering trims, based on the trim component
  • Trim textures will be loaded from the appropriate folder in the textures/trims/entity directory
    • For example, armor with wolf_body layers will fetch trims from textures/trims/entity/wolf_body

Moved Textures

  • All equipment-related textures have been moved to subfolders of the textures/entity/equipment directory
    • Player armor textures have been moved to textures/entity/equipment/humanoid and textures/entity/equipment/humanoid_leggings
      • <material>_layer_1 textures have been renamed to <material>, and moved into the humanoid subdirectory
      • <material>_layer_2 textures have been renamed to <material>, and moved into the humanoid_leggings subdirectory
      • leather_layer_1_overlay and leather_layer_2_overlay textures have been renamed to leather_overlay in their respective subdirectories
    • wolf_armor and wolf_armor_overlay textures have moved to textures/entity/equipment/wolf_body/ and have been renamed to armadillo_scute and armadillo_scute_overlay respectively
    • turtle_layer_1 has been renamed to turtle_scute
    • Llama decor textures have been moved to textures/entity/equipment/llama_body
    • Horse armor textures have been moved to textures/entity/equipment/horse_body
    • The Elytra texture has been moved to textures/entity/equipment/wings/elytra
  • Armor trim textures have also been moved to match the folder structure of the regular equipment textures
    • Textures in textures/trims/models/armor have been divided between textures/trims/entity/humanoid and textures/trims/entity/humanoid_leggings
    • For leggings textures, the _leggings suffix is dropped

Shaders & Post-process Effects

Developer's Note: Although it is possible in Resource Packs, overriding Core Shaders is considered as unsupported and not an intended Resource Pack feature. These shaders exist as part of the internal implementation of the game, and as such, may change at any time as the game's internals evolve. We understand that overriding Core Shaders is used for very cool Resource Pack features, many of which lack supported alternatives. We would like to provide better, supported alternatives in the future.

  • Shader program configurations can now specify preprocessor define directives to apply to their linked shaders
    • Many shader implementations have been merged by making use of this
  • The format of core shader and post-processing shader configurations have been consolidated
  • The format of post-processing effect configurations have been updated
  • The ChunkOffset uniform in terrain shaders has been renamed to ModelOffset
  • The rendertype_entity_glint_direct shader has been removed (replaced by rendertype_entity_glint)
  • The rendertype_entity_translucent_cull shader has been removed (replaced by rendertype_item_entity_translucent_cull)

Shader Program Definitions

  • Program definitions for post-processing effects (assets/<namespace>/shaders/program/<name>.json) have been made consistent with core shader definitions (assets/<namespace>/shaders/core/<name>.json)
    • The blend field has been removed, as it had no use
    • The attributes field has been removed, instead the Position attribute will always be bound
    • The provided uniforms have been consolidated with those provided to core shaders
      • Time has been renamed to GameTime
  • The vertex and fragment shader references in program definitions (including post-processing effects) are now namespaced shader ids
    • A vertex shader <namespace>:<path> will resolve to assets/<namespace>/shaders/<path>.vsh
    • A fragment shader <namespace>:<path> will resolve to assets/<namespace>/shaders/<path>.fsh
  • Shader source files are no longer required to be in the shaders/core subdirectory, this only exists for organization
  • Added defines field to program definitions (object with fields)
    • Allows GLSL define directives to be injected into the shader source, which can be referenced in the shader
    • values (map of string to string)
      • Will be injected as #define <key> <value> at the top of the file
    • flags (list of strings)
      • Will be injected as #define <key> at the top of the file

Shader Imports

  • The #moj_import directive now supports namespaced includes with absolute paths
    • For example, #moj_import <minecraft:fog.glsl> will import assets/minecraft/shaders/include/fog.glsl
  • Relative imports are not namespaced and behave as before

Post-process Effect Definitions

  • Post-processing effect configuration has been moved out of the assets/<namespace>/shaders/post directory to just assets/<namespace>/post_effect
  • Vertex and fragment shaders used by these effects have been moved from assets/<namespace>/shaders/program to assets/<namespace>/shaders/post
  • name has been renamed to program, and is now a namespaced id of a shader program configuration
    • <namespace>:<path> will resolve to assets/<namespace>/shaders/<path>.json
  • intarget and auxtargets have been merged into a single inputs list, as specified by the input format below
  • outtarget has been renamed to output with the same format
  • targets is now a map between target name and target definition, as opposed to a list
    • Inline target names are replaced with an empty object
      • For example, ["swap"] becomes {"swap": {}}
    • Target definitions with a specific size remain the same, with the name field moved into the map key
      • For example, [{"name": "potato", "width": 16, "height": 16}] becomes {"potato": {"width": 16, "height": 16}}
Input Format

For both render target and texture inputs, the following fields may be specified:

  • sampler_name: string - prefix to set up both _Sampler and _Size uniforms
    • For example, "sampler_name": "Diffuse" will link to the DiffuseSampler and DiffuseSize uniforms
    • This was previously always DiffuseSampler and InSize for intarget
    • For auxtargets, the name defined the sampler uniform, and the size was given as AuxSize<index>
  • bilinear: boolean (default: false) - if true, the input will be sampled with a bilinear filter
    • This formerly only existed on texture inputs, however now functions for render targets
    • For render targets, replaces the now removed use_linear_filter field on the pass definition

For inputs from a render target, the following fields may be specified:

  • target: namespaced id - the render target id
    • Either a custom target id defined in the same file, or minecraft:main to reference the main screen target
    • This replaces the former id field, which was a free-form string
  • use_depth_buffer: boolean (default: false) - true to sample from the depth texture, false to sample from the color texture
    • This replaces the former :depth suffix applied to the target id

For inputs from a static texture, the following fields may be specified:

  • location: namespaced string - the location to a static texture file that can be sampled by the effect
    • As the id field did before, this resolves to a texture at assets/<namespace>/textures/effect/<path>.png
  • width: positive integer - width in pixels of the texture
  • height: positive integer - height in pixels of the texture
External Targets
  • The 'Fabulous' graphics transparency post-processing config no longer specifies the sorted framebuffers as custom targets
    • These are instead imported in the same way as the minecraft:main target
    • translucent, itemEntity, particles, weather, clouds are now minecraft:translucent, minecraft:item_entity, minecraft:particles, minecraft:weather, and minecraft:clouds respectively
  • The entity outline processing shader similarly imports the minecraft:entity_outline target

Translation Removals and Renames

  • During load some deprecated translation strings will now be removed and/or renamed
  • Packs that use these translations will need to re-add them manually
  • The full list is available in the /assets/minecraft/lang/deprecated.json file inside the game's JAR file

Creaking mob

The Creaking mob spawns at night in the Pale Garden biome if there is a Creaking Heart block that has been generated in a Pale Oak tree. Gameplay features:

  • Creaking will activate if a surivival or adventure mode player is within 12 blocks of it and looks at it
  • Creaking stays active while there is a survival or adventure mode player within 32 blocks of it

Creaking Heart

A Creaking Heart is a “living” block generating in Pale Oak trees, covered on all sides by Pale Oak wood logs. It can spawn a Creaking mob when it is nighttime, and it is placed between two correctly aligned Pale Oak Logs.

  • Is active during the night and dormant during the day
  • Sends a trail of particles towards the connected Creaking when the Creaking gets hit by the player
  • When Creaking Heart block is destroyed, the connected Creaking is removed
  • Comparators attached to the Creaking Heart block will output a signal strength dependent on the distance to the connected Creaking

New system for Pale Garden ambient sounds

Ambient sounds in the Pale Garden biome do not come from the biome settings, but are generated by blocks found in the biome.

  • Pale Hanging Moss emits subtle atmospheric sounds when it is attached to Pale Oak Logs and Pale Oak Leaves
  • Creaking Heart block emits a set of eerie sounds when it is active during the night and surrounded by Logs on all sides

Redstone Experiments

Added a new Experiment containing various Redstone-related changes. This can be enabled by selecting "Redstone Experiments" in the Experiments menu when creating a world.

Please note that the experimental features behind this toggle are not aimed at any future release at this time.
Instead, this is a place for us to try out changes and gather feedback.
We are excited to hear what you think about these changes: please share your feedback on the feedpack page.

Redstone Wire

  • The performance impact of Redstone wire (connected blocks of Redstone Dust) has been improved
  • Redstone wire now only triggers block updates on blocks that may receive power from the wire
  • Before a line of wire causes block updates, the new signal strength of all connected wires is set
  • The update order around Redstone wire has been changed
    • The aim is to make wire work the same, independent of position and global orientation
    • When possible the order is deterministic based on the context the updates are caused in
    • When there is not enough context to fully determine the order, the rest is picked at random

Developer's note: We know that randomness in Redstone is usually unwanted.
We've used it here because we've made things deterministic whenever it makes sense, and sometimes it just doesn't make sense - and we don't want some hidden state (like location-based hashes!) determining the order and making machines work differently at different coordinates or in different orientations.

Order in Which a Line of Wire Changes
  • When a line of wire turns on, the wires closer to the power source will cause block updates first
  • When a line of wire turns off, the wires closer to where the power source was, will cause block updates first
  • When two wires have the same distance to the power source, the one to the left in the direction of travel updates first
    • If there is not enough context to know the direction of travel (when the wire was powered from above or below), the side to update first is picked at random

Ari is testing the experimental Redstone changes, standing in the middle of a machine comprised of four sets of two pistons each facing each other. The leftmost piston according to the power source of the two is always extending regardless of orientation.

Block Updates Around a Wire
  • The order in which blocks around the wire update is based on the direction the wire received an update from
  • The order of the updates is: back, front, left, right, down, up
  • When the updates are further distributed through solid blocks, the same order is applied there

Known Issues

As this experiment only changes Redstone wire, interactions with other components may not always act as expected, especially when it comes to update orders.

The removal of excessive neighbor updates around wire affects behavior of Quasi-Connectivity based contraptions. We plan to address these issues at a later point.

Minecart Improvements

Added a new Experiment containing various movement changes to Minecarts. This can be enabled by selecting "Minecart Improvements" in the Experiments menu when creating a world.

Our long term goal is to make vehicle travel, like Minecarts, a viable option for players compared to other late-game options which currently dominate most playstyles. To achieve this, we aim to make riding Minecarts a smooth experience, with consistent and predictable motion and rotation. With this feature toggle we are laying a foundation to build upon in the future. We are aware of that these changes will break some existing contraptions, which is why we want to collaborate with the community to shape the upgrade and future experience of riding Minecarts.

Please note that the experimental features behind this toggle are not aimed at any future release at this time. Instead, this is a place for us to try out changes and gather feedback.

We are excited to hear what you think about these changes: please share your feedback on this feedback page.

An experimental Minecart with Chest is speeding up on a powered circular railway, ready to be launched onto the distant track across the water.

Movement Changes

  • Minecarts will articulate their movement better when going fast, riding on the rail all the time
    • Minecarts will now smoothly turn along with the track and are less likely to halt or derail
  • Minecarts can now jump better
    • They keep their vertical momentum when the track ends with a slope
    • Minecarts will tilt to visually articulate while in the air
    • No rail grinding sound is played when Minecarts are flying through the air
  • Added a new accessibility setting that makes players follow the rotation of Minecarts they ride
    • Defaults to off
    • Only has effect when within a world with the experiment enabled
  • Added new gamerule minecartMaxSpeed that changes the maximum speed of Minecarts
    • Defaults to 8 and goes up to 1000 blocks per second.
    • Setting it to a specific value does not guarantee that a minecart will reach that particular max speed - there are built in air resistances and similar effects that the speed added through slopes or powered rails need to overcome
    • This gamerule only exists in worlds with the experiment enabled

Minecart Changes

  • Minecarts can no longer be placed within another Minecart by the player
    • Dispensers can still "stack" Minecarts by placing them on the Rail, even if there is another Minecart already there
  • Minecarts can now consistently be placed next to each other along a track
  • Minecarts now pick up mobs more consistently when moving along a track
  • Minecarts will no longer phase through blocks on slopes

Known Impact

  • We are aware that these changes will affect certain contraptions such as 'piston bolts', which may now not work at all, or have their behavior changed
  • Very delicate rail networks will have their timings changed due to slight changes in speeds, movement distance, friction etc.
  • Contraptions that rely on Minecarts snapping to rails will no longer work, or have their behavior changed

Fixed bugs in 1.21.2

Around 319 bugs were fixed in this release. View the list on the issue tracker.
