writeCustomDataToNbt

protected 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.

writeCustomDataToNbt in class Entity

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.

Ticks this entity.

Overrides:

tick in class Entity

See Also:

API Note:

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

setVelocity

public void setVelocity(double x,
 double y,
 double z,
 float power,
 float uncertainty)

Sets velocity and updates rotation accordingly.

The velocity and rotation will be set to the same direction.

The direction is calculated as follows: Based on the direction vector (x, y, z), a random vector is added, then multiplied by the speed.

Parameters:

x - the X component of the direction vector

y - the Y component of the direction vector

z - the Z component of the direction vector

power - the speed

uncertainty - the fuzziness added to the direction; player usages have 1.0 and other mobs/tools have higher values; some mobs have difficulty-adjusted values

setVelocity

public void setVelocity(Entity shooter,
 float pitch,
 float yaw,
 float roll,
 float speed,
 float divergence)

Sets velocity and updates rotation accordingly.

Parameters:

shooter - the entity who shot this projectile; used to add the shooter's velocity to this projectile

pitch - the pitch

yaw - the yaw

roll - the roll

speed - the speed

divergence - the fuzziness added to the direction; player usages have 1.0 and other mobs/tools have higher values; some mobs have difficulty-adjusted values

createSpawnPacket

public Packet<ClientPlayPacketListener> createSpawnPacket(EntityTrackerEntry entityTrackerEntry)

Returns a packet to notify the clients of the entity's spawning.

API Note:

Subclasses should return new EntitySpawnS2CPacket(this), unless they use a custom spawning packet.

onSpawnPacket

public void onSpawnPacket(EntitySpawnS2CPacket packet)

Called on the client when the entity receives a spawn packet.

This sets the entity's position, angles, ID, and UUID. Subclasses can override this to initialize additional fields.

canModifyAt

public boolean canModifyAt(ServerWorld world,
 BlockPos pos)

Returns whether the entity can modify the world at pos.

This returns true for most entities. Players check World.canPlayerModifyAt(net.minecraft.entity.player.PlayerEntity, net.minecraft.util.math.BlockPos) to prevent them from modifying entities in the spawn protection or outside the world border. ProjectileEntity delegates it to the owner if the owner is a player; if the owner is a non-player entity, this returns the value of GameRules.DO_MOB_GRIEFING, and ownerless projectiles are always allowed to modify the world.

Overrides:

canModifyAt in class Entity

Returns:

whether the entity can modify the world at pos

getTargetingMargin

public float getTargetingMargin()

Returns the margin around the entity's bounding box where the entity targeting is still successful.

Overrides:

Returns:

API Note:

ExplosiveProjectileEntity overrides this method to return 1.0f, which expands the ghast fireball's effective hitbox.

damage

public 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

  #isInvulnerableTo
