Item effect code or Plugin?

Hey,I was wondering if anyone has a code to set a (item) to give effect (potion) for example I use BlazePowder and it gives strength effect and then the BlazePowder goes down (Removed Or Goes Down By 1)

 

PHP:

   public function onHeld(PlayerItemHeldEvent $event){   
        $player = $event->getPlayer();
        $hand = $player->getInventory()->getItemInHand();
        $count = $hand->getCount();
        $air = Item::get(0, 0, 1);
        
        if($hand->getId() == 1){

        $player->sendMessage("You Have ".$count." Stones!");
        $speed = Effect::getEffect(Effect::SPEED);
        $speed->setDuration($count);
        $player->addEffect($speed);
        $player->getInventory()->setItemInHand($air);
        }   
    }

 

Hmm thank you,I'll figure how to use I I really appreciate it new to this codding thing

 

Because idont think people have one :/

 

If you request code, this belongs in the development section. If you are requesting a plugin, then it belongs in the Request section. Make up your mind. What do you want?
