ItemFrameDropItemPacket - Error

Hello everyone, i have a problem
i want to cancel ItemFrameDropItemPacket, but my code is not working
what is wrong with my code ?

Code:

public function itemDrop(ItemFrameDropItemPacket $event){
            $event->setCancelled(true);
}

 

You are trying to cancel a packet, not an event?

 

If you only want to protect item frames from taking out the item in it, use:

PHP:

public function onTouch(PlayerInteractEvent $event) {
        $block = $event->getBlock();
        $player = $event->getPlayer();
        $level = $player->getLevel();
        if($level->getName() === "Shop") { // if you don't want players to take out the item in world "Shop"
            if(!$player->hasPermission("itemframes.touch")) { // if the player has permissions
                if($block->getId() === Block::ITEM_FRAME_BLOCK) {
                    $event->setCancelled();
                }
            }
        }
    }

 

i was using this code when version 1.0.7 and that was working very well
but thank you WinterBuild7074 for the code

 

Using $level->getFolderName() might be better than $level->getName(). Most people change the folder name instead of the actual world name in level.dat.
