ItemStack to String

Hello, i need to save and load ItemStacks to a db do i would be so greatful if you can give me a function to transform a ItemStack with enchantments, lore, metadata etc. to a String and back?

 

You just need to put all the data you want to save into a string, seperated with a ';' for example.
If you cant to convert it back, split the string.

 

Ok heres an example store it in a string like this.
materialtype:amount:enchantments:lore:name
then split it around : and create an itemstack accordingly.

 

I believe ItemStacks can be saved to .ymls, as there is a method getItemStack(String) in FileConfiguration: lemme check this, one sec

EDIT: Ooooh, it appears it does!
I used yml.set("itemstack", anItemStack), and got this:

Code:

itemstack:
  ==: org.bukkit.inventory.ItemStack
  type: REDSTONE_LAMP_OFF
  damage: 2
  amount: 4
  meta:
    ==: ItemMeta
    meta-type: UNSPECIFIC
    display-name: A displayname
    lore:
    - Huehue
    - Potatoe
    enchants:
      DAMAGE_ALL: 10

Then, you can use ItemStack itemstack = yml.getItemStack("itemstack") to get it back

 

Ahh I forgot about that.
However I believe the OP wants to store it in a database...

 

Ah yeh, converting to a String and back:

Code:

// Create a random ItemStack
ItemStack is = new ItemStack(Material.REDSTONE_LAMP_OFF, 4, (short) 2);
is.addUnsafeEnchantment(Enchantment.DAMAGE_ALL, 5);
ItemMeta meta = is.getItemMeta();
meta.setDisplayName("A displayname");
meta.setLore(Arrays.asList("Huehue", "Potatoe"));
is.setItemMeta(meta);
 
// ItemStack to String
Map<String, Object> serializedMap = is.serialize();
String itemStackString = String.valueOf(serializedMap);
 
// Back to ItemStack
ItemStack originalItemStack = ItemStack.deserialize(serializedMap);
 
// Output:
// {type=REDSTONE_LAMP_OFF, damage=2, amount=4, meta=UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name=A displayname, lore=[Huehue, Potatoe], enchants={DAMAGE_ALL=5}}}

However, you may need to make a method for converting the String (that you save in the database) to a Map<String, Object> that is used to create an ItemStack

 

Wait wait wait.. whaaaa.. I made a serializer for this, but yet something already exists..

 

ItemStack implements ConfigurationSeriable so you can convert it easy into a Map<String,Object> and back. You dont need to make your own serializer

 

If you checked out the resources thread, I made a way to transform these maps into a string, and then back into a map. I think I know how it works now.
