Returns the sound category for sounds from this entity.

This is used by Entity.playSound(SoundEvent, float, float) and defaults to SoundCategory.NEUTRAL. Hostile entities should override this to return SoundCategory.HOSTILE.

Overrides:

Ticks this entity.

See Also:

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

readCustomDataFromNbt

protected 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.
