23w06a is the fourth snapshot for Java Edition 1.19.4, released on February 8, 2023,^[1] which introduces display entities, /damage command, damage types and tags, and fixes bugs.

Additions

Non-mob entities

Display entities

Including block display, item display, and text display.
- Like 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), thirdperson_lefthand, thirdperson_righthand, firstperson_lefthand, firstperson_righthand, head, gui, ground, fixed.
- Block display (block_display): Displays a block state, does not display block entities, even if they would normally be created on block placement (like chest).
  - block_state: Block state to display. Same format as item held by 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

Game rule

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

/damage

A new command to apply damage to entities, with following syntaxes:
- /damage <target> <amount> [<damageType>] [at <location>]
- /damage <target> <amount> [<damageType>] [by <entity>] [from <cause>]
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 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 bed exploding in 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 arrow projectile while cause might be a skeleton.

/execute

Added /execute summon sub-command, with the following syntax:
- /execute summon <entity> -> execute
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

Data pack

Added 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:
```
{
	"exhaustion": 0.1,
 	"message_id": "arrow",
	"scaling": "when_caused_by_living_non_player"
}
```
- 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 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.
  - effects: Optional field controlling how damage manifests when inflicted on players. Possible values:
    - hurt (default): The default hurt sound.
    - thorns: Thorns hurt sound.
    - drowning: Drowning sound.
    - burning: A single tick of burning sound.
    - poking: Berry bush poke sound.
    - freezing: Freeze tick sound.
  - death_message_type: Optional field that controls if special death message variants are used. Possible values:
    - 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 tags control many aspects of how damage from different sources are interpreted.
