Make A Menu On Player's Inventory

Hi, I want to make a menu on player's inventory.
so, when the player clicked a block, then it will run a command. Like in the image

I curently using PlayerItemHeldEvent()

PHP:

public function onItemHeld(PlayerItemHeldEvent $event)
{
    $player = $event->getPlayer();
    if ($event->getItem()->getCustomName() == "TEST") {
        $player->sendTip(TextFormat::BOLD . TextFormat::DARK_RED . "Wow, You Choosed TEST");
    }
}


But, how we know when the player clicked the item in the air, or clicked the item while opening inventory

 

use InventoryTransactionEvent or EntityInventoryChangeEvent

 

I'll try it

 

so how do i check what item he clicked?

 

Use PlayerInteractEvent and check the ID, Name or instanceof and it's class.

 

why you use sendTip it will be different on Pocket and Classic UI.

 

Here's a great example of how to check which item was clicked "ChestShop" by @Muqsit
