Usability
FastNbt is easier to use compared to NBT API and requires less boilerplate code.

Creating an head texture
Code (Java):

NItem nItem = new nItem ( new ItemStack (Material. PLAYER_HEAD ) ) ;
nItem. setSkull ( "dummy", "eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvYjc4ZWYyZTRjZjJjNDFhMmQxNGJmZGU5Y2FmZjEwMjE5ZjViMWJmNWIzNWE0OWViNTFjNjQ2Nzg4MmNiNWYwIn19fQ==" ) ;
nItem. save ( ) ; // If finished editing
 
Renaming an item
NOTE: FastNBT supports only Compound strings.
If you want to use legacy notation you have to call the Spigot API as usual.
Code (Java):

NItem nItem = new nItem ( new ItemStack (Material. STONE ) ) ;
nItem. setDisplayNameCompound ( "{\"text\":\"Example Compound Name\",\"color\":\"blue\"}" ) ;
nItem. save ( ) ; // If finished editing
 
Setting an attribute modifier
Code (Java):

nItem. setAttributeModifier (
        "minecraft:generic.movement_speed",
        1,
        6,
        "bro",
        "mainhand",
        1337,
        1337
) ;
nItem. save ( ) ; // If finished editing
 
Setting an attribute modifier (manual method)
Code (Java):

NList attributes = nItem. getOrAddList ( "AttributeModifiers", NBTType. Compound ) ;
NCompound attribute = new NCompound ( ) ;
attribute. setString ( "AttributeName", attributeName ) ;
attribute. setInt ( "Operation", operation ) ;
attribute. setInt ( "UUIDLeast", uuidLeast ) ;
attribute. setInt ( "UUIDMost", uuidMost ) ;
attribute. setDouble ( "Amount", amount ) ;
attribute. setString ( "Name", name ) ;
attribute. setString ( "Slot", slot ) ;
attributes. addCompound (attribute ) ;
 
Limitations
Currently, supports only items.
