Interaction entities are a technical entity, useful for map or data pack creators to see who the last player to click on a certain spot is. They can only be created with the /summon or /execute summon commands. Interaction entities are invisible, invincible and of a custom size. Their bounding box can be viewed via the F3 + B debug shortcut.

Interaction entities record the UUID of the last player that left-clicked and right-clicked them, and the time at which the interaction happened. If response is set to true, left-clicking an interaction entity plays a punching sound, and right-clicking it makes the player's arm swing.

You can check information on who last left-clicked and right-clicked on the interaction entity with the /data get entity command. This information can be useful in datapack and map creation. You can also change their size to match the area you want to be checked. Although there is seemingly no limit on the size that may be specified, there still appears to be an effective limit of 22.6 blocks in each dimension. Interactions and attacks will not be detected on the part of the hitbox beyond 3.3 blocks away from the entity's position (which is at the center of the hitbox) in the negative X and Z directions, and the same is true in the positive directions beyond 19.3 blocks away. In the Y direction, the bottom of the hitbox is always at the Y coordinate of the entity's position, so interactions and attacks are not detected beyond 22.6 blocks above the Y coordinate.

• Interacting with (right-clicking) an interaction entity triggers player_interacted_with_entity.
• Attacking (left-clicking) an interaction entity triggers player_hurt_entity.

The interaction entity targets the player who last interacted with it. That makes the following possible:

• /execute on attacker execute as the last player who attacked (left-clicked) the entity.
• /execute on target execute as the last player who interacted with (right-clicked) the entity.

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