Interact issues

I would like to ask if the player has the compass in his hand and if so the inventory should open
Does not work. Please help

Code:

package de.boulyt.lobby.listeners;import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.inventory.InventoryType;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.Inventory;

public class NavigatorListener implements Listener {

    @EventHandler
    public void ballFiring(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        Action a = event.getAction();
        if ((a == Action.PHYSICAL) || (event.getItem() == null) || (event.getItem().getType() == Material.COMPASS)) {
            Inventory inventory = Bukkit.createInventory(null, InventoryType.BREWING, "§aNavigator");
            player.openInventory(inventory);
        }

    }

}

 

You should add this line to prevent your event to be called twice, maybe that should help

if (event.getHand().equals(EquipmentSlot.HAND))
{

}

Try to add System.out.println("") something to see if your event is called too

 

The action is only physical if you're interacting with pressure plates, tripwire hooks, etc. Instead, check if it's Action.RIGHT_CLICK_BLOCK or Action.RIGHT_CLICK_AIR
