Display entities are entities useful for map or data pack creators to display various things. There are Block Displays, Item Displays and Text Displays, which are used to display blocks, items and texts respectively. They can be created only with the /summon or /execute summon command.

Behavior

Much like markers, display entities do not move, do not take damage, do not make sounds, and have no collision. They do not obstruct the placement of blocks, nor do they push players or other entities away from their own position. Unlike markers, display entities are sent to the client for rendering and do count toward in the E value (total amount of entities) listed on the debug screen.

Display entities have no hitbox. Using the debug key combination F3 + B, which normally draws the hitboxes of all visible entities, does not show a hitbox for display entities. Using F3 + I while aiming at a display entity does not copy the entity data to the clipboard.

Usage

Display entities can be summoned only by commands. Block Displays, Item Displays, and Text Displays have the default NBT data of {block_state:{Name:"minecraft:air"}}, {item:{id:"minecraft:air",count:0}}, and {text:'{"text":""}'} respectively and so, if spawned without any NBT data specified, they are not visible. By modifying the entities' data one can easily edit their display content and other visual effects, and rotate, scale, or translate the model.

Item Displays

Item Display entities can display any item in the game using the item tag.

Using the Item Display entity with custom_model_data can easily display any custom model.

For the Item Display entity, in addition to directly modifying the NBT, the displayed item can also be modified using the /loot and /item commands with the slot container.0.

Per default, the location of an item display without transformations represents the center of the item.

Block Displays

Block Display entities can display any block in the game using the block_state tag.

The location of a block display without transformations represents the north-west-bottom (negative XYZ) corner of the block.

Text Displays

Text Display entities can display any text using the text tag.

The displayed text is only visible from one side, which is without transformations the direction the text display is rotated towards.

The location of a text display without transformations represents the bottom center of the text.

Interpolation

Some visual effects of these entities can be interpolated over game time to display gradient animation.

All fields marked as "Interpolated" in #Entity data below can be interpolated. These properties do not interpolate independently of each other.

Any change to any of these properties causes client to record both the previous and changed values of these properties. Since server synchronizes entities with the client at most once per game tick, multiple changes within one game tick still count as a single change.

The entity rendering is interpolated over time between the previous values and the current values. The game time to start interpolation (entity fully in previous state) is start_interpolation (gametime, in game ticks). Trying to set a value less than 0 sets it to the current game time. The game time when interpolation ends (entity fully in current state) is start_interpolation + interpolation_duration (gametime, in game ticks).

Entity data

Display entities have entity data associated with them that contain various properties of the entity.

Item Display:

• [NBT Compound / JSON Object] Entity data
  • Tags common to all entities see Template:Nbt inherit/entity/template[show]
  • Tags common to all display entities see Template:Nbt inherit/display entity/template[show]
  • [NBT Compound / JSON Object] item: The item to display.
    • Tags common to all items see Template:Nbt inherit/itemnoslot/template[show]
  • [String] item_display: The model to display. Describes item model transform applied to item (as defined in display field in model JSON). Can be none, thirdperson_lefthand, thirdperson_righthand, firstperson_lefthand, firstperson_righthand, head, gui, ground, and fixed. Defaults to none.

Block Display:

• [NBT Compound / JSON Object] Entity data
  • Tags common to all entities see Template:Nbt inherit/entity/template[show]
  • Tags common to all display entities see Template:Nbt inherit/display entity/template[show]
  • [NBT Compound / JSON Object] block_state: The block state to display.
    • Block state see Template:Nbt inherit/block state/template[show]

Text Display:

• [NBT Compound / JSON Object] Entity data
  • Tags common to all entities see Template:Nbt inherit/entity/template[show]
  • Tags common to all display entities see Template:Nbt inherit/display entity/template[show]
  • [String] alignment: Text alignment direction. Can be center, left, and right. Defaults to center.
  • [Int] background: The background color, arranged by ARGB. Since pixel with an alpha channel less than 0.1 are discarded when rendering in vanilla shader, the background becomes fully transparent when A is less than 26 (0x1A). Defaults to 1073741824 (0x40000000). Interpolated.
  • [Boolean] default_background: If true, rendering uses default text background color (same as in chat), which overrides [Int] background. Defaults to false.
  • [Int] line_width: Maximum line width used to split lines (note: new line can be also added with \n characters). Defaults to 200.
  • [Boolean] see_through: Whether the text be visible through blocks. Defaults to false.
  • [Boolean] shadow: Whether the text is displayed with shadow. Defaults to false.
  • [String] text: The text to be displayed in the format of raw JSON text, which are resolved with the context of the display entity.
  • [Byte] text_opacity: Alpha value of rendered text. Value ranges from 0 to 255. Values up to 3 are treated as fully opaque (255). Similar to the background, the text rendering is discarded for values between 4 and 26. NBT stores the value as signed byte, -128 to 127. Defaults to -1, which represents 255 and is completely opaque. SNBT to NBT handles conversion from unsigned to signed, but if needed, replace values greater than 127 with alpha-256 or alphaUB. Interpolated.

History

[hide]Java Edition
1.19.4			23w06a				Added Block Display, Item Display and Text Display.
			Pre-release 4				When a new interpolation is started, it now starts from the current state instead of the final state.
			Release Candidate 1				Interpolation always starts at the beginning on client tick.
							Field interpolation_start is replaced with start_interpolation, with a different meaning.
							start_interpolation describes amount of ticks from the start of next client tick after receiving an update to start of interpolation. For example, value 0 means that interpolation starts at the beginning of next client tick after receiving the update.
							start_interpolation is not stored in entity data. When using /data commands, if interpolated value is updated, but start_interpolation is not present in modified tag, interpolation continues from the time of previous update, but with new values.
1.20			23w12a				Previous values are now always discarded if interpolation_duration is 0.
							Made sure that render properties are applied at the same time (so block_state is applied at the same time as transformation, i.e. at next tick after receiving update).
							Entities are not rendered unless initial data is received. That means display entities might not show on the first tick.
			23w16a				item_display items have been rotated 180 degrees around Y axis to better match transformation applied when rendering items on armor stand head and in item frames.
1.20.2			23w31a				Display entities now start updating their client-side position and rotation on the first tick after an update.
							On the server, position and rotation are still updated immediately.
							Duration of this interpolation is controlled by the field teleport_duration.
							Note: behavior while riding remains unchanged from previous versions.
