Solved Backpack Plugin with NBT Tags?

Hi!
Im currently working on a backpack plugin. For the backpack design i use the InvMenu Plugin developed by Muqsit(Thank you for that if you read it ) Here is the link: https://github.com/Muqsit/InvMenu
Now i want to safe the Items which are set by the player with NBT Tags. I already started with:

PHP:

$menu->setInventoryCloseListener(function (Player $player, Inventory $inventory) {

            for ($slots = 0; $slots <= 40; $slots++) {
                $pName = $player->getName();
                $item = $inventory->getItem($slots);
                $nbt = $item->getNamedTag() ?? new CompoundTag("", []);
                $nbt->inv = new StringTag($pName,"items");
                $item->setNamedTag($nbt);
            }

(I hope this is right) My Problem is now that when the player opens the Backpack the Items need to load(of course) but where can i "get" the Items from to even check if they have the right tag? Thanks for your help

 

Is it a dumb question?

 

Try using a list tag and then using int or sttinh tags for every slot you want to be saved

 

Probably not

 

Take a look at how MUQSIT himself did it.

https://github.com/Muqsit/PlayerVaults/tree/master/src/muqsit/playervaults/database

 

Take a look at Item::jsonSerialize/Item::jsonDeserialize or Item::nbtSerialize/Item::nbtDeserialize depending on how you are saving the data

 

Alright i tried this:
(This is where i save the items)

PHP:

$menu->setInventoryCloseListener(function (Player $player, Inventory $inventory) {

            for ($slots = 0; $slots <= 40; $slots++) {
                $pName = $player->getName();
                $item = $inventory->getItem($slots);
                $value = $item->nbtSerialize();
                $this->saveItemToConfig($value);
            }

        });

And this is where i try to give the Items

PHP:

for ($slots = 1; $slots <= 40; $slots++) {
            $items = $this->giveItemFromConfig($player);
            $cook = $items->nbtDeserialize();
            $inv->setItem($slots,$items);


        }

And these are the functions:

PHP:

 public function saveItemToConfig(Item $item) {
        $cfg = new Config($this->getDataFolder().'config.sl', Config::SERIALIZED);
        $cfg->set('item', $item);
        $cfg->save();
    }

    public function giveItemFromConfig(Player $player) {
        $cfg = new Config($this->getDataFolder().'config.sl', Config::SERIALIZED);
        $item = $cfg->get('item');
        return $item;
    }

And this is the failure:

Code:

 [Server thread/CRITICAL]: Error: "Call to a member function nbtDeserialize() on bool" (EXCEPTION) in "plugins/Backpack/src/Tim/Backpack/Main" at line 100

I do not really unterstand the nbtDeserialize function. Someone could help me?

 

If you are saving into a config then I would suggest using Item::jsonSerialize/Item::jsonDeserialize
If you want to save directly into player.dat, then take a look at https://github.com/alvin0319/Offhand/blob/master/src/alvin0319/Offhand/Offhand.php

 

Thank you, the link was very helpful!
