 +Make sure that the projectile that you are launching with this item is indeed your custom ''ProjectileEntity''. Verify this by checking ''PackedSnowballEntity snowballEntity = new PackedSnowballEntity(world, user);''.

 Now, we are finished with creating an item for the ''ProjectileEntity''. Keep in mind that if you do not understand how to create an item, refer to the [[https://fabricmc.net/wiki/tutorial:items|"Item" tutorial]]. Now, we are finished with creating an item for the ''ProjectileEntity''.
