protected Entity.MoveEffect getMoveEffect()

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

tick

public void tick()

Ticks this entity.

Overrides:

tick in class Entity

See Also:

• LivingEntity.tickMovement()
• MobEntity.mobTick()

API Note:

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

Implementation Note:

damage

public boolean damage(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 Entity.isInvulnerableTo(net.minecraft.entity.damage.DamageSource) and return early.

Overrides:

damage in class Entity

Returns:

whether the entity was actually damaged

See Also:

• Entity.isInvulnerableTo(net.minecraft.entity.damage.DamageSource)

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.
