Solved Can't update inventory.

Hello! I'm trying to update player inventory after creating it.

In this code "player.updateInventory();" throws NullPointerException even though inventory is created.

Code:

Bukkit.createInventory(player, InventoryType.PLAYER).setItem(2, pvpoff);
player.updateInventory();

Note: Inventory is created in another method when onPlayerRespawnEvent is triggered.

 

Well I have tried that but it still throwed NullPointerException since the inventory have no contents

 

Code:

 
public class LPvP implements Listener{
public void addItem(UUID playerid){
        Player player = Bukkit.getPlayer(playerid);
        ItemStack pvpoff = new ItemStack(Material.WOOL, 1);
        ItemMeta pvpoffmeta = pvpoff.getItemMeta();
        pvpoffmeta.setDisplayName(ChatColor.translateAlternateColorCodes('%', "%f%lPvP:%c OFF"));
        pvpoff.setItemMeta(pvpoffmeta);
        Bukkit.createInventory(player, InventoryType.PLAYER).setItem(2, pvpoff);
        player.updateInventory();
}
    @EventHandler
    public void onRespawn(PlayerRespawnEvent event) {
        UUID playerid = event.getPlayer().getUniqueId();
        addItem(playerid);
    }
}

This is without all imports and Its not main class.

Appearently there is difference from getting player from event and then adding contents to inventory than getting player UUID from event then getting player with Bukkit.getPlayer() and adding contents to inventory.

Fixed by passing player got from event to method and then adding item with player.getInventory().setItem(2, pvpoff) and then player.updateInventory()
