Solved Transforming ingots to blocks

Hello, so i was creating a plugin where if there are ingots in a chest it transformes them into blocks and this is my code:

PHP:


public function matchItem(Item $neededItem, ChestInventory $inv) {
        $items = $inv->getContents();
        foreach($items as $key => $item) {
            if($item->equals($neededItem)) {
                return $key;
            }
            return false;
        }
    }

foreach ($contents as $item){ // on playerinteractevent
                                $uses = $nbt->getInt("usesCondense"); // dont mind this
                                if ($item->getId() === Item::IRON_INGOT){
                                    if($item->getCount() >= 9){
                                        $ev->setCancelled();
                                        $condensable = true; // dont mind this
                                        $transform = floor($item->getCount() / 9);
                                        $remove = $transform * 9;
                                        $slot = $this->matchItem($item, $inv);
                                        for($i = 0; $i < $transform; $i++){
                                            $p->getInventory()->addItem(Item::get(Item::IRON_BLOCK));
                                            $inv->setItem($slot, Item::get($item->getId(), 0, $item->getCount() - $remove)); // here's the problem
                                        }
                                    }
                                }
                            }

however it works and gives me the right count of iron blocks too but it doesn't substract the count of all the ingots from the $remove variable but it subtracts only 1 slot (and i want it to be in all the slots which have iron ingots) i hope u understand to help me.

 

That might help: https://forums.pmmp.io/threads/removing-items-from-players-invent-problem.8686/#post-67327

 

I would suggest counting all the items and removing them before calculating and adding the blocks

PHP:

$count = 0;
foreach ($contents as $slot => $item){
    if ($item->getId() === Item::IRON_INGOT){
        $count += $item->getCount();
        $inventory->clear($slot);
    }
}
$blocks = floor($count/9);
$inventory->addItem(Item::get(Item::IRON_BLOCK,0,$blocks));
$remain = $count % 9;
if($remain > 0)
$inventory->addItem(Item::get(Item::IRON_INGOT,0,$remain));


 

Thank you very much guys! it works
