23w06a is the fourth Minecraft:snapshot for Minecraft:Java Edition 1.19.4, released on February 8, 2023,<ref>Template:Snap</ref> which introduces Minecraft:display entities, Template:Cmd command, damage types and Minecraft:tags, and fixes bugs.

Additions

Non-mob entities

Minecraft:Display entities

• Including block display, item display, and text display.
  • Like Minecraft:markers, don't tick and have no collisions or physics.
  • Models render at entity position, with normal rotation around X and Y axis (so it can be controlled by teleport commands), but also with additional arbitrary model transform.
• 2 new data types added, each of them has 2 forms, but only one for saving, as following:
  • rotation
    • Quaternion form (used for saving): array of 4 numbers, describing components (x, y, z, w).
    • Axis-angle form: object with following fields:
      • axis: 3D vector.
      • angle: Angle in radians.
  • transformation: Arbitrary affine transform, composed as following fields and following order:
    • Matrix form: array of 16 numbers, describing row-major matrix.
    • Decomposed form (used for saving): object with following fields:
      • translation: 3D vector.
      • left_rotation: rotation object.
      • scale: 3D vector.
      • right_rotation: rotation object.
• Some properties of display entities can be interpolated, to create gradual changes over time for clients, instead of instantaneous jumps.
  • Display entities keep track of current and previous values of interpolated values:
    • All properties marked as "interpolated" are part of a single interpolation set.
    • Any update to interpolated property cause all values of interpolation set to be saved as "current".
      • Data command executions that do not change value of property (even if it's present in NBT) do not count as updates.
      • Updates are synchronized to clients at most once per tick, so multiple updates within command still count as single update.
    • Previous current values are saved as "previous".
    • If interpolation is enabled, entity transitions between "previous" and "current" values over time.
    • Start of interpolation (entity fully in "previous" state) is defined by field interpolation_start (game time, in ticks).
      • Set to -1 to load current game time instead.
    • End of interpolation (entity fully in "current" state) is defined as interpolation_start + interpolation_duration (in ticks).
• Every entity in family has the following fields:
  • transformation: transformation applied to model (after normal entity orientation). Defaults to identity. Interpolated.
  • billboard: option to control if entity should pivot to face player when rendered:
    • fixed: No rotation (default).
    • vertical: Entity can pivot around vertical axis.
    • horizontal: Entity can pivot around horizontal axis.
    • center: Entity can pivot around center point.
  • brightness: If present, overrides light values used for rendering. Omitted by default (which means rendering uses values from entity position). Object has two fields:
    • sky: Value of skylight, from 0 to 15.
    • block: Value of block light, from 0 to 15.
  • view_range: Maximum view range of this entity. Actual distance depends on client-side render distance and entity distance scalling. Default value 1.0 (roughly the same as fireball).
  • shadow_radius: Size of shadow. Defaults to 0 (no shadow). Interpolated.
  • shadow_strength: Strength of the shadow. Controls the opacity of the shadow as a function of distance to block below. Defaults to 1. Interpolated.
  • width, height: Describe size of culling bounding box. Bounding box spans vertically y to y+height and horizontally width/2 in all directions from entity position. If either field is set to 0, culling is disabled. Both default to 0.
  • glow_color_override: Override glow border color. Defaults to 0 (use team color).
• Besides common fields, these entity types also have some exclusive fields for their different usages:
  • Item display (item_display): Displays a single item stack (stack can be changed with commands by setting slot inventory.0).
    • item: Item stack to display. Same format as in inventory.
      • Example: {id: "minecraft:dirt", Count: 1}
    • item_display: Describes item model transform applied to item (as defined in display section in model JSON)
      • Values: none (default), Template:Cd.
  • Block display (block_display): Displays a block state, does not display block entities, even if they would normally be created on block placement (like Minecraft:chest).
    • block_state: Block state to display. Same format as item held by Minecraft:endermen.
      • Example: {Name:"minecraft:dirt"}.
  • Text display (text_display): Displays a text component (backgrounds uses new shader types rendertype_text_background and rendertype_text_background_see_through).
    • text: Text to display. Components are resolved with the context of the display entity.
    • line_width: Line width used to split lines (note: new line can be also added with \n characters). Defaults to 200.
    • text_opacity: Opacity (alpha component) of rendered text. Defaults to 255. Interpolated.
    • background: Color of background. Includes alpha channel. Defaults to 0x40000000. Interpolated.
    • default_background: If true, rendering uses default text background color (same as in chat). Defaults to false.
    • shadow: Should text be displayed with shadow. Defaults to false.
    • see_through: Should text be visible through blocks. Defaults to false.
    • alignment: How text should be aligned.
      • Values: center (default), left, right.

Command format

Minecraft:Game rule

• Added doVinesSpread.
  • Defaults to true.
  • Determines if Minecraft:vines spread to nearby blocks.
  • Does not affect Minecraft:cave vines, Minecraft:twisting vines and Minecraft:weeping vines.

Template:Cmd

• A new command to apply damage to entities, with following syntaxes:
  • Template:Cmd
  • Template:Cmd
• Parameters:
  • target: The entity to damage.
  • amount: Amount of damage to inflict.
  • damageType: The type of damage to inflict.
    • This determines how the damage affects the entity as well as which Minecraft:death message is displayed.
  • location: The location the damage originated at (when no entity caused the damage).
    • For instance, it might represent the location of a Minecraft:bed exploding in Minecraft:the Nether.
  • entity: The entity inflicting the damage.
  • cause: The cause of the damage, in the case of indirect damage.
    • Example: When shot by an arrow, the entity is the Minecraft:arrow projectile while cause might be a Minecraft:skeleton.

Template:Cmd

• Added Template:Cmd sub-command, with the following syntax:
  • Template:Cmd
• This sub-command is for summoning new entity and binding context (@s) to it. Meant to simplify entity setup and reduce need for raw NBT editing.

General

Minecraft:Data pack

• Added Minecraft:damage types, which are a new registry.
  • Determines how damage is handled by the game.
  • Includes which attributes the damage has as well as which death message is used when an entity dies due to that type of damage, example: <syntaxhighlight lang="json">

{ "exhaustion": 0.1,

	"message_id": "arrow",

"scaling": "when_caused_by_living_non_player" }</syntaxhighlight>

• • Fields:
    • message_id: The message id used for deaths caused by this damage type.
      • Combined with other string fragments to form a translation key.
    • exhaustion: The amount of hunger Minecraft:exhaustion caused by this damage type.
    • scaling: Whether this damage type scales with difficulty levels. Possible values:
      • never: Damage is always the same.
      • always: Damage always scales with difficulty.
      • when_caused_by_living_non_player: Damage scales with difficulty if it was caused by a living entity who is not a player.

      • default (default): No special death message logic is applied.
      • fall_variants: Show a variant of fall damage death instead of a regular death message, e.g. death.fell.assist.item.
      • intentional_game_design: Show the intentional game design message instead of a regular death message.
  • Damage type Minecraft:tags control many aspects of how damage from different sources are interpreted.
