InventoryGUI Teleporting

I know bukkit is starting to die but i still wont give up coding. Therefor i am trying to make a inventory that hows all of the players online and you can teleport to one of them if you click on their head.

Everything works except one thing. It doesn't teleport.

Everything opens like it should and what not but i cant figure out why this line of code wont work..

Code:

Player playerBeingClicked=Bukkit.getPlayer(((SkullMeta)e.getCurrentItem().getItemMeta()).getOwner());

Here is all of my code.

Code:

    @EventHandler
    public void onClick(InventoryClickEvent e)
    {
        if(e.getInventory().getTitle().equalsIgnoreCase("CLICK on a name"))
        {
            if(e.getCurrentItem() != null && e.getCurrentItem().getType() != null)
            {
                e.setCancelled(true);
                Player player = (Player) e.getWhoClicked();
                Player playerBeingClicked = Bukkit.getPlayer(((SkullMeta) e.getCurrentItem().getItemMeta()).getOwner());
                if(player.getName() == playerBeingClicked.getDisplayName()) return;
                if(playerBeingClicked != null)
                {
                    player.teleport(playerBeingClicked);
                }
            }
        }
    }
   
    @EventHandler
    public void compassmenu(PlayerInteractEvent  e) {
        Action a = e.getAction();
        ItemStack is = e.getItem();
       
        if (a == Action.PHYSICAL || is == null || is.getType()==Material.AIR) {
            return;
        }
       
        if(is.getType()==Material.COMPASS ){
            Main.openSpectateGUI(e.getPlayer(), Bukkit.getOnlinePlayers(), 1, new ItemStack(Material.SKULL_ITEM, 1, (byte) 3));
        }
    }

@Ty Cleere

Instead of
Player playerBeingClicked=Bukkit.getPlayer(((SkullMeta)e.getCurrentItem().getItemMeta()).getOwner());
Do
Player playerBeingClicked=Bukkit.getPlayer(((SkullMeta)e.getCurrentItem().getItemMeta()).getDisplayName());

Since the player you want to teleport to's name it on the skull, isn't it?

 

@NicksTheBoss I actually thought of that. I tried using .getDisplayName() and .getName() But i get this when i try that. My error moves to line 35 instead of the first one.

More null checks, line 35 of eventlistener is null

 

@SuperOriginal I see that it is a null on line 35. But where would i check to see if it is null. Where would i put that null check in? What is null about it?

 

Well the only thing that really could be null is players and index z...

 

I don't know what line that is, check the components of the line and see which ones could possibly be null, and check for it before you use it.

 

if(e.getInventory().getTitle().equalsIgnoreCase("CLICK on a name")

Inventory inventory = Bukkit.createInventory(null, invSize, "Select a player...");

When does the name of the inventory change to "CLICK on a name"?

 

@TwerkinCraft Oh i see that.. i changed that to match in both spots and i dont get the error. but now it just doesnt do anything. so imma do some testing and see what i get. Thanks
