public void writeCustomDataToNbt(NbtCompound nbt)

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

readCustomDataFromNbt

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.

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 LivingEntity

Returns:

whether the entity was actually damaged

canStartRiding

protected boolean canStartRiding(Entity entity)

Returns whether this entity can ride entity.

Returning false causes the entity to be unable to ride other entities. For example, WitherEntity overrides this to return false, so withers cannot ride boats or minecarts. Note that this check can be bypassed by passing true to Entity.startRiding(Entity, boolean).

This is the opposite of Entity.canAddPassenger(net.minecraft.entity.Entity).
