Entity Tasks

Entity-related operations, including base entities, living entities (LivingEntity), and potion effects.

---

Lookup

entity.get

Looks up an entity by UUID.

• Request: { "uuid": "<uuid>" }
• Return: { "uuid": "<uuid>" } | null

---

Attribute Read/Write

Basic Information

Task	Request	Return
entity.getType	{ "uuid": "<uuid>" }	string (minecraft registry key, e.g. minecraft:zombie)
entity.getName	{ "uuid": "<uuid>" }	string
entity.getCustomName	{ "uuid": "<uuid>" }	string (empty string means not set)

entity.setCustomNameVisible	{ "uuid": "<uuid>", "value": <boolean> }	true

Location and World

Task	Request	Return
entity.getWorld	{ "uuid": "<uuid>" }	string (world name)
entity.getLocation	{ "uuid": "<uuid>" }	{ "x": <double>, "y": <double>, "z": <double>, "yaw": <double>, "pitch": <double>, "world": "<name>" }
entity.teleport	{ "uuid": "<uuid>", "x": <double>, "y": <double>, "z": <double>, "yaw": <double>, "pitch": <double>, "world": "<name>" }	true

State Toggles

Task	Request	Return
entity.isGlowing	{ "uuid": "<uuid>" }	boolean
entity.setGlowing	{ "uuid": "<uuid>", "value": <boolean> }	true
entity.isInvulnerable	{ "uuid": "<uuid>" }	boolean
entity.setInvulnerable	{ "uuid": "<uuid>", "value": <boolean> }	true
entity.isSilent	{ "uuid": "<uuid>" }	boolean
entity.setSilent	{ "uuid": "<uuid>", "value": <boolean> }	true
entity.hasGravity	{ "uuid": "<uuid>" }	boolean
entity.setGravity	{ "uuid": "<uuid>", "value": <boolean> }	true

Riding System

Task	Request	Return
entity.getPassengers	{ "uuid": "<uuid>" }	string[] (UUID array)
entity.getVehicle	{ "uuid": "<uuid>" }	string | null (UUID of the ridden entity)
entity.getBoundingBox	{ "uuid": "<uuid>" }	{ "minX","minY","minZ","maxX","maxY","maxZ" } (double)

Lifecycle Operations

Task	Request	Return	Description
entity.remove	{ "uuid": "<uuid>" }	true	Removes the entity
entity.isDead	{ "uuid": "<uuid>" }	boolean	Whether the entity is dead

---

LivingEntity — extends the base entity

Health

Task	Request	Return
entity.getHealth	{ "uuid": "<uuid>" }	number
entity.setHealth	{ "uuid": "<uuid>", "value": <double> }	true
entity.getMaxHealth	{ "uuid": "<uuid>" }	number

---

Potion Effects

All potion effect operations target LivingEntity.

Parameter Format

{
  "type": "minecraft:speed",
  "duration": 200,
  "amplifier": 1,
  "ambient": false,
  "particles": true,
  "icon": true
}

Field	Type	Required	Default	Description
type	string	Yes	—	Potion effect type name (Paper PotionEffectType name, lowercase, e.g. speed, poison)
duration	int	No	200	Duration (in ticks, 20 = 1 second)
amplifier	int	No	0	Level (0 = level I, 1 = level II)
ambient	bool	No	true	Whether it is an ambient effect (fewer particles)
particles	bool	No	true	Whether to show particles
icon	bool	No	true	Whether to show the icon in the inventory

Tasks

Task	Request	Return
entity.addPotionEffect	{ "uuid": "<uuid>", ...PotionEffect params }	true. type is case-insensitive; ambient/particles/icon default to true (same structure as the input); an unknown type returns an error
entity.removePotionEffect	{ "uuid": "<uuid>", "type": "<potion>" }	true
entity.clearPotionEffects	{ "uuid": "<uuid>" }	true
entity.getActivePotionEffects	{ "uuid": "<uuid>" }	[{ "type": "<lowercase>", "duration": <int>, "amplifier": <int>, "ambient": <bool>, "particles": <bool>, "icon": <bool> }] — same structure as the input

Basic Operations (2026-08-13)

Task	Request	Return
entity.getVelocity	{ "uuid": "<uuid>" }	{ "x": <double>, "y": <double>, "z": <double> } (blocks/second)
entity.setVelocity	{ "uuid": "<uuid>", "x": <double>, "y": <double>, "z": <double> }	true
entity.getFireTicks	{ "uuid": "<uuid>" }	int (0 = not on fire)
entity.setFireTicks	{ "uuid": "<uuid>", "value": <int> }	true
entity.getTicksLived	{ "uuid": "<uuid>" }	int (ticks lived)
entity.setTicksLived	{ "uuid": "<uuid>", "value": <int> }	true
entity.isOnGround	{ "uuid": "<uuid>" }	boolean
entity.damage	{ "uuid": "<uuid>", "amount": <double>, "damager": "<uuid>"? }	true (damager is the optional damaging entity)
entity.setTarget	{ "uuid": "<uuid>", "targetUuid": "<uuid>" } or { "uuid": "<uuid>", "world": "<name>", "x": <double>, "y": <double>, "z": <double>, "speed": <double>? }	true

setTarget semantics (2026-08-13): sets an AI goal — not guaranteed to take effect (it depends on the runtime, entity type, and pathfinding capability). The target is an entity (targetUuid, Mob.setTarget) or a location (world+x+y+z, Pathfinder.moveTo, optionally with a speed movement speed). Only works on mob entities; non-mob/entities that cannot pathfind are silently ignored.

For the format rules and full lists of value ranges involved (entity types, potion effects, etc.), see the Values Appendix.
