event problem

hi . im trying to write a new plugin . im using EntityInventoryChangeEvent . i want to remove item on this event but i will get this error from console
[14:39:44] [Server thread/CRITICAL]: RuntimeException: "Recursive event call detected (reached max depth of 50 calls)" (EXCEPTION) in "src/pocketmine/event/Event" at line 83
the code

$sender->getInventory()->removeItem(Item::get(2, 0, 1));

 

I think this error appears when the even is in a loop.

So it do something like this:

PHP:

onEvent();

function doEvent() {
   onEvent();
}

 

Explane more please . Should i do removing in other function ?

 

send all the function

 

PHP:

public function onInventoryTransactionEvent(EntityInventoryChangeEvent $event)  {
            $sender = $event->getEntity();
                        if($sender instanceof Player){
                            $source = $event->getOldItem();
                            $target = $event->getNewItem();
                                    if($source->getNamedTag()->hasTag("Enchant")){
                                        $level = $source->getNamedTag()->getInt("Level");
                                        $this->removeItemFrom($sender,$source);
                                        $enchant = CustomEnchantManager::getEnchantmentByName($enchantName);
                                                if ($enchant == null) {
                        Utils::errorForm($sender, T::RED . "Invalid enchantment.");
                        return;
                    }
                                        $item = $target;
                                                    if (!$sender->hasPermission("piggycustomenchants.overridecheck")) {
                                                        if (!Utils::itemMatchesItemType($item, $enchant->getItemType())) {
                                                            
                                                                $sender->sendMessage(T::RED . T::RED . "The item is not compatible with this enchant.");
                                                    return;
                                                }
                                                
                                                if ($level > $enchant->getMaxLevel()) {
                                                    
                                                    $sender->sendMessage(T::RED . T::RED . "The max level is " . $enchant->getMaxLevel() . ".");
                                                    
                                                    return;
                                                }
                                                
                                                if ($item->getCount() > 1) {
                                                    $sender->sendMessage(T::RED . T::RED . "You can only enchant one item at a time.");
                                                return;
                                                }
                                                
                                                    if (!Utils::checkEnchantIncompatibilities($item, $enchant)) {
                                                        $sender->sendMessage(T::RED . T::RED . "This enchant is not compatible with another enchant.");
                                                    return;
            }
        }
            
        
        $item->addEnchantment(new EnchantmentInstance($enchant, $level));
        
          
        $source->setLore([T::YELLOW."\nYou Can't Use This Anymore"]);
        $event->setNewItem($item);
                                    
                                    }
                        }
     }

now i use a function to remove item but i get error agian . i just need to remove $source item

 

You cannot manage the items in player's inventory in function which handles that.

Player change item
-> event will handle it
-> you change item in player's inventory
-> event will handle it
-> ...

That's loop

 

what should i do to delete the source item ?

 

use better checks (if)

 

give me code please

 

I don't know... Your code doesn't make sense for me.. What's the purpose of the code?

 

Try to add some tag to save if the item is already checked... Then check just the items without this tag

 

Im trying to make this plugin .

I just dont know how to remove book ($source)

 

Add the enchnat directly

 

code please

 

Give me the code where you handle the form

 

piggy ce

 

That doesn't seem as valid code... If you aren't satisfied with that plugin, ask plugin's author for fix that...

 

im the author . its working . did you watch the video ?

 

let me send you full plugin .
