Method Details

getMoveEffect

protected Entity.MoveEffect getMoveEffect()

Returns the possible effect(s) of an entity moving.

Overrides:

getMoveEffect in class Entity

Implementation Note:

If an entity does not emit game events or play move sounds, this method should be overridden as returning a value other than ALL allows skipping some movement logic and boost ticking performance.

API Note:

Subclasses should override this and add to the builder any data that needs to be tracked.

tick

public void tick()

Ticks this entity.

Overrides:

tick in class Entity

See Also:

• LivingEntity.tickMovement()
• MobEntity.mobTick(net.minecraft.server.world.ServerWorld)

API Note:

This can be overridden to add additional logics. super.tick(); should be called in those cases.

Implementation Note:

expensiveUpdate

private void expensiveUpdate()

Performs an expensive update.

Implementation Requirements:

Called every second (every EXPENSIVE_UPDATE_INTERVAL ticks). This method first checks if the orb still has a nearby target, and assigns a new target if there is none. It then tries to merge nearby experience orbs.

official	b	Lbva;b(Lbtp;)Z

damage

public final boolean damage(ServerWorld world,
 DamageSource source,
 float amount)

Applies a damage to this entity. The exact implementation differs between subclasses.

LivingEntity has health value, and damaging the entity decreases it. This also handles shields, extra damage to helmets for falling blocks, setting the attacker, playing hurt sound, etc.

Some entities like ItemEntity also have health value, which the overridden method decrements. There also exist several entities, like EndCrystalEntity, where any damage discards the entity (perhaps with an explosion).

If this is overridden, it must check the result of

invalid reference

#isInvulnerableTo

and return early.

Specified by:

damage in class Entity

Returns:

whether the entity was actually damaged

• invalid reference

writeCustomDataToNbt

public void writeCustomDataToNbt(NbtCompound nbt)

Writes custom data to nbt. Subclasses have to implement this.

NBT is a storage format; therefore, a data from NBT is loaded to an entity instance's fields, which are used for other operations instead of the NBT. The data is written back to NBT when saving the entity.

readCustomDataFromNbt

public void readCustomDataFromNbt(NbtCompound nbt)

Reads custom data from nbt. Subclasses have to implement this.

NBT is a storage format; therefore, a data from NBT is loaded to an entity instance's fields, which are used for other operations instead of the NBT. The data is written back to NBT when saving the entity.

nbt might not have all expected keys, or might have a key whose value does not meet the requirement (such as the type or the range). This method should fall back to a reasonable default value instead of throwing an exception.

onPlayerCollision

public void onPlayerCollision(PlayerEntity player)

Called when a player collides with the entity. Does nothing by default.

This should be overridden if the collision logic is specific to players, such as picking up item entities, experience orbs, or arrows.

Overrides:

isAttackable

public boolean isAttackable()

Returns whether the entity can be attacked by players.

Note that this is not called for most entities defined in vanilla as unattackable (such as ItemEntity and ExperienceOrbEntity) as trying to attack them kicks the player.

Overrides:

isAttackable in class Entity

Returns:

whether the entity can be attacked by players
