How do I create an enchanted book that can be used in an anvil?

I know how to use the regular meta methods that we have now, but I need to know how to change an item in hand from a book (or spawned in 403 (enchanted book)) into a yellow-named enchanted book that will legitimately work in an anvil. Is there any way to do this?

EDIT: I know about EnchantmentStorageMeta, but I'm not quite sure how to use it. In addition, I know that you probably want me to do an if statement on whether or not their item in hand is a book/enchanted book... that's what I'm already doing. But, enchanting an enchanted book (spawned in) does not work anvil-wise...

 

Get a book and set the EnchantmentStorageMeta

Code:java

EnchantmentStorageMeta esm = (EnchantmentStorageMeta)book.getItemMeta();
// do stuff with the meta, check the javadocs for method
book.setItemMeta(esm);

 

When I did that, there was no noticeable change. It stayed the exact same way it was.

 

What is the difference between
meta.addEnchant()
and
meta.addStoredEnchant()?

Code:

public ItemStack addBookEnchantment(ItemStack item, Enchantment enchantment, int level){
        EnchantmentStorageMeta meta = (EnchantmentStorageMeta) item.getItemMeta();
        meta.addStoredEnchant(enchantment, level, true);
        item.setItemMeta(meta);
        return item;
    }

and then do:

Code:

addBookEnchantment(item, enchantment, level);

addStoredEnchant(Enchantment, int) is for the books. Adding actual enchantments to weapons is just .add(Unsafe)Enchantment(Enchantment, int) for the ItemStack and .addEnchant() for the ItemMeta

 

thank you

 

I used it the same way (except not from an external method) in my old attempts, I guess I was missing something :\

 

use the external method... and this:

Code:

public static Enchantment getEnchantmentByCommonName(String name){
        name = name.toLowerCase();
        if(name.toLowerCase().equalsIgnoreCase("fire_protection")) return Enchantment.PROTECTION_FIRE;
        if(name.toLowerCase().equalsIgnoreCase("blast_protection")) return Enchantment.PROTECTION_EXPLOSIONS;
        if(name.toLowerCase().equalsIgnoreCase("projectile_protection")) return Enchantment.PROTECTION_PROJECTILE;
        if(name.toLowerCase().equalsIgnoreCase("protection")) return Enchantment.PROTECTION_ENVIRONMENTAL;
        if(name.toLowerCase().equalsIgnoreCase("feather_falling")) return Enchantment.PROTECTION_FALL;
        if(name.toLowerCase().equalsIgnoreCase("respiration")) return Enchantment.OXYGEN;
        if(name.toLowerCase().equalsIgnoreCase("aqua_affinity")) return Enchantment.WATER_WORKER;
        if(name.toLowerCase().equalsIgnoreCase("sharpness")) return Enchantment.DAMAGE_ALL;
        if(name.toLowerCase().equalsIgnoreCase("smite")) return Enchantment.DAMAGE_UNDEAD;
        if(name.toLowerCase().equalsIgnoreCase("bane_of_arthropods")) return Enchantment.DAMAGE_ARTHROPODS;
        if(name.toLowerCase().equalsIgnoreCase("knockback")) return Enchantment.KNOCKBACK;
        if(name.toLowerCase().equalsIgnoreCase("fire_aspect")) return Enchantment.FIRE_ASPECT;
        if(name.toLowerCase().equalsIgnoreCase("looting")) return Enchantment.LOOT_BONUS_MOBS;
        if(name.toLowerCase().equalsIgnoreCase("power")) return Enchantment.ARROW_DAMAGE;
        if(name.toLowerCase().equalsIgnoreCase("punch")) return Enchantment.ARROW_KNOCKBACK;
        if(name.toLowerCase().equalsIgnoreCase("flame")) return Enchantment.ARROW_FIRE;
        if(name.toLowerCase().equalsIgnoreCase("infinity")) return Enchantment.ARROW_INFINITE;
        if(name.toLowerCase().equalsIgnoreCase("efficiency")) return Enchantment.DIG_SPEED;
        if(name.toLowerCase().equalsIgnoreCase("unbreaking")) return Enchantment.DURABILITY;
        if(name.toLowerCase().equalsIgnoreCase("silk_touch")) return Enchantment.SILK_TOUCH;
        if(name.toLowerCase().equalsIgnoreCase("fortune")) return Enchantment.LOOT_BONUS_BLOCKS;
        if(name.toLowerCase().equalsIgnoreCase("thorns")) return Enchantment.THORNS;
        return null;
    }

so you can use the common name instead of all those obscure names
