Java Edition 1.19.4

1.19.4 is an upcoming minor update to with no set release date, which adds the  and  commands, makes technical changes, and fixes bugs. Aside from the aforementioned changes, this version will also release the rest of the 1.20 features under the same data pack.

Non-mob entities

 * Display entities
 * Including Block Display, Item Display, and Text Display, for flexible display of blocks, items and text.
 * Like marker, 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:
 * Quaternion form (used for saving): array of 4 numbers, describing components (x, y, z, w).
 * Axis-angle form: object with following fields:
 * : 3D vector.
 * : Angle in radians.
 * : 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:
 * : 3D vector.
 * : object.
 * : 3D vector.
 * : object.
 * Some properties of display entites can be interpolated, to create gradual changes over time for clients, instead of instantenous 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 will 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 will still count as single update.
 * Previous current values are saved as "previous".
 * If interpolation is enabled, entity will transition between "previous" and "current" values over time.
 * Start of interpolation (entity fully in "previous" state) is defined by field (game time, in ticks).
 * Set to to load current game time instead.
 * End of interpolation (entity fully in "current" state) is defined as +  (in ticks).
 * Every entity in family has the following fields:
 * : applied to model (after normal entity orientation). Defaults to identity. Interpolated.
 * : option to control if entity should pivot to face player when rendered:
 * : No rotation (default).
 * Entity can pivot around vertical axis.
 * Entity can pivot around horizontal axis.
 * Entity can pivot around center point.
 * : If present, overrides light values used for rendering. Omited by default (which means rendering uses values from entity position). Object has two fields:
 * : Value of skylight, from 0 to 15.
 * : Value of block light, from 0 to 15.
 * : 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).
 * : Size of shadow. Defaults to 0 (no shadow). Interpolated.
 * : Strength of the shadow. Controls the opacity of the shadow as a function of distance to block below. Defaults to 1. Interpolated.
 * : Describe size of culling bounding box. Bounding box spans vertically to  and horizontally  in all directions from entity position. If either field is set to 0, culling is disabled. Both default to 0.
 * : Override glow border color. Defaults to 0 (use team color).
 * Besides common fields, these entitiy types also have some exclusive fields for their different usages:
 * Item Display : Displays a single item stack (stack can be changed with commands by setting slot ).
 * : Item stack to display. Same format as in inventory.
 * Example:
 * : Describes item model transform applied to item (as defined in section in model JSON)
 * Values: (default),.
 * 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 to display. Same format as item held by endermen.
 * Example:.
 * Text Display : Displays a text component (backgrounds uses new shader types ).
 * : Text to display. Components are resolved with the context of the display entity.
 * : Line width used to split lines (note: new line can be also addded with characters). Defaults to 200.
 * : Opacity (alpha component) of rendered text. Defaults to 255. Interpolated.
 * : Color of background. Includes alpha channel. Defaults to 0x40000000. Interpolated.
 * : If true, rendering uses default text background color (same as in chat). Defaults to false.
 * : Should text be displayed with shadow. Defaults to false.
 * : Should text be visible through blocks. Defaults to false.
 * : How text should be aligned.
 * Values: (default),.
 * Values: (default),.


 * Interaction
 * A new type of entity that records s and s. Interactions are invisible and of a custom size, with following fields:
 * : Width of the entity's bounding box (default ).
 * : Height of the entity's bounding box (default ).
 * : An action object, records the last attack action on the entity.
 * : An action object, records the last interaction action on the entity.
 * : Boolean specifying if interacting should trigger a response (arm swing, sound effects, etc - default ).
 * Introduced action object accordingly. When an action is stored, it always has two fields:
 * : The UUID (in standard integer array format) of the player performing the action.
 * : The timestamp of the game tick when the event happened (stored as a long).
 * This made following command usage possible:
 * Execute command as the last player who attacked the entity when using.
 * Execute command as the last player who interacted with the entity when using.
 * Advancement triggers also got triggered, when:
 * Interacting with an interaction entity:.
 * Attacking an interaction entity:.

 * : Amount of damage to inflict.
 * : The type of damage to inflict.
 * This determines how the damage affects the entity as well as which death message is displayed.
 * : The location the damage originated at (when no entity caused the damage).
 * For instance, might represent the location of a bed exploding in the Nether.
 * : The entity inflicting the damage.
 * : The cause of the damage, in the case of indirect damage.
 * Example: When shot by an arrow, the is the arrow projectile while  might be a skeleton.
 * : The entity inflicting the damage.
 * : The cause of the damage, in the case of indirect damage.
 * Example: When shot by an arrow, the is the arrow projectile while  might be a skeleton.


 * A new command to allow entities to start or stop riding other entities, syntaxes:
 * : makes a single target mount a single vehicle, will fail if:
 * is a player;
 * is already riding a vehicle;
 * and are the same entity;
 * is already a passenger (direct or indirect) of.
 * : dismounts from any vehicle it is riding, will fail if  is not riding anything.
 * : dismounts from any vehicle it is riding, will fail if  is not riding anything.

 * : Thorns hurt sound.
 * : Drowning sound.
 * : A single tick of burning sound.
 * : Berry bush poke sound.
 * : Freeze tick sound.
