Solved Saving custom inventory

Hello, I am making a plugin that allow you to create a shop and you can sell item's on it on a GUI but I don't know how to save the inventories I have been trying for a long time all I know to do is save the inventory on the config by using that method:

Code:

    public static void saveInventory(Inventory inv, FileConfiguration config, String path) {
        for (int i = 0; i<inv.getSize();i++) {
            if (inv.getItem(i)!=null) {
                config.set(path + "." + i, inv.getItem(i));
            } else {
                if (config.isItemStack(path + "." + i)) {
                    config.set(path + "." + i, null);
                }
            }
        }
    }    

and i'm saving it by using "InventoryCloseEvent" and the method is:

saveInventory(getInventory(p), config, p.getName() + "'s_Inventory");

the getInventory(p) that for the player's shop like a inventory per player I think you got it

and that how I get it on the config:

Code:

DK_IMNP's_Inventory:
  '0':
    ==: org.bukkit.inventory.ItemStack
    type: STAINED_CLAY
    damage: 10
    meta:
      ==: ItemMeta
      meta-type: UNSPECIFIC
      display-name: "\xa7r\xa7lSTAINED_CLAY x1"
      lore:
      - ''
      - "\xa78\xa7lItem By:"
      - "\xa7r\xa7lDK_IMNP"
      - "\xa78\xa7lPrise:"
      - "\xa7r\xa7l1"
      - "\xa78\xa7lItem Number:"
      - "\xa7r\xa7l0"

but the problem is I don't really know how to load it...
please anyone help me.
Thank you! ☺

Sorry for my English, English is not my first language!

 

@DK_DEV Are you trying to save the player's inventory in a YAML file and then setting it back to that inventory later? If so then you can just save the player's inventory contents and set it back later.

 

I'm new on java so I don't really know how to do that and ye i'm saving it on the YML File but I don't really know how to put back the items if you open the inventory again... Can you please help me?

 

If you want to save the player's inventory (including armor) then do this:

Code:Java

getConfig().set(/*path*/, player.getInventory().getContents());

And to get it:

Code:Java

player.getInventory().setContents(getConfig().getStringList(/*path*/));

That should work, please let me know how it goes. (I hope this is what you meant/wanted)

 

Ugh I get an error on:

player.getInventory().setContents(getConfig().getStringList(/*path*/));

because I use a method which is per player inventory that is the method:

static Inventory getInventory(Player player) {
Inventory i = inventories.get(player);

if(i == null) {
i = Bukkit.createInventory(null, 54, "§7§lShop");
inventories.put(player, i);
}
return i;
}

and the error is:

The method setContents(itemStack[]) in the type Inventory is not applicable for the arguments (List<String>)

 

Please don't use that. Use the "ChatColor.translateAlternateColor(" instead.

 

Oh my bad, i think it might be getConfig().get(/*path*/), i don't remember and i can't check at the moment.

 

Oh okay

and it doesn't work btw

Sure I'll

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@DK_DEV Try this instead:

Code:Java

//To save it
getConfig().set(/*path*/, player.getInventory().getContents());
 
//To load it
ItemStack[] contents = (ItemStack[]) getConfig().get(/*path*/);
player.getInventory().setContents(contents);

Hope this works for you.

 

I get an error this is the error:

And i'm using a custom inventory btw.

 

The "contents" is null. Make sure that the config contains that path before you try to get it.

 

Oh okay I'll try that

Edit: I made the "contents" not null and I checked it on the config but when I reload the server and open the inventory I'll get this error:

Any help please?

@Zombie_Striker

But everything is working fine but before I reload the server if I reloaded it I'll get this error...

Oh wait this time it didn't give me a error but it didn't put the items back when

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

When an ItemStack[] is saved to a config, it is converted to a List<ItemStack>, so you can't just cast it back to an ItemStack[].

You should be able to just change the "ItemStack[]" to "List<ItemStack>" and that should fix the problem. If you have other code that still relies on it as an array, you may need to then take the List and do some conversions (not casting) to convert it back to an ItemStack[].

 

can u please show me how to do it because i'm still learning on java

Sorry for a lot of questions..

 

List<ItemStack> contentsLIST = (List<ItemStack>) getConfig().get(p.getName() + "'s Inventory");

ItemStack[] contents=new ItemStack[contentsLIST.size()];
contents = contentsLIST .toArray(contents );

 

and then I do

getInventory(p).setContents(contents);

or no?

 

@Zombie_Striker OMG it's working thank you soo much ;D
