save player inventory like another object

how can i save PlayerInventory object without holder only whole inventopry because i want to save player inventory and add another items. But when i make $inv = $p->getInventory() i can´t add items into saved inventory without add items to real player´s inventory. and then i can make

PHP:

$inv = saved inventory;
$p->getInventory(setContents($inv->getContents()));


can i use clone $p->getInventory() ?

Don't! That will result in memory leaks.
Save it item by item. Convert each item between array and Item object (save ID, damage and count in array) and save it using a data serialization language like YAML or JSON.

i know but it is harder get free slots or adding items to the saved inventory and i want to save inventory only for a while so memory will free in few seconds

Btw, what AREmemory leaks in PM?

Saving a reference to an object that should be garbaged. For example, referencing to a player object that should be garbaged after player quit.

so how can i add item to saved inventory in array[$slot => $item]

is it right?

PHP:

foreach($inv as $slot => $item){
    if($item->getId() === 0){
        $item = $CustomItem;
    }
}


If you mean to save it into the harddisk, save it in a YAML or JSON file.

PHP:

function saveInventory(Inventory $inventory, $file){
  $items = [];
  foreach($inventory->getContents() as $slot => $item){
    $items[$slot] = [$item->getId(), $item->getDamage(), $item->getCount()];
  }
  file_put_contents($file, json_encode($items));
}
function readInventory(Inventory $inv, $file){
  $items = json_decode(file_get_contents($file));
  $inv->setContents([]);
  foreach($items as $k => $v)
    $inv->setItem($k, $v);
}

no i want to save it only for few time. I want to make shop and i need to check if saved inventory contains specified amount of specified item and if yes so ass some Item to saved inventory.
my not working code:

PHP:

public function clickItem(Player $p, Item $buyItem, Item $costItem, $inv){ //$inv is saved inventory
        $buy = false;
        foreach($inv as $slot => $item){
            if($buy === false){
                if($item->getId() === $costItem->getId() && $item->getDamage() === $costItem->getDamage() && $item->getCount() >= $costItem->getCount()){
                    $inv[$slot] = Item::get($costItem->getId(), $costItem->getDamage(), $item->getCount() - $costItem->getCount());
                    $buy = true;
                    continue;
                }
            }
            if($item->getId() === Item::AIR or $item->getCount() <= 0){
                $item = $buyItem;
                $p->sendMessage($this->plugin->plugin->getPrefix().TextFormat::GREEN."Koupil jsi {$buyItem->getName()})");
            }
        }
        $p->sendMessage($this->plugin->plugin->getPrefix().TextFormat::RED."Nemas dostatek surovin");
    }


i think check if player have space in saved inventory doesn´t work

Use code from LIAB (by aliuly)

What there is not any code which i want .

You can copy and edit functions loadInventory() and saveInventory()

Read thread again

If you're doing BedWars Shop (I think so), I think that you can save player inventory, then he buys something an you load his inventory and add item in it. It's method I use in BedWars

i need to add item to saved inventory
