public Entity getEffectCause()

Returns the cause entity of any effect applied by this projectile. If this projectile has an owner, the effect is attributed to the owner; otherwise, it is attributed to this projectile itself.

Returns:

writeCustomDataToNbt

protected void writeCustomDataToNbt(NbtCompound nbt)

Writes custom data to nbt. Subclasses has 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.

Specified by:

writeCustomDataToNbt in class Entity

readCustomDataFromNbt

protected void readCustomDataFromNbt(NbtCompound nbt)

Reads custom data from nbt. Subclasses has 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.

setVelocity

public void setVelocity(double x,
 double y,
 double z,
 float speed,
 float divergence)

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

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

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

onSpawnPacket

public void onSpawnPacket(EntitySpawnS2CPacket packet)

canModifyAt

public boolean canModifyAt(World 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
