Solved Trying to make it so a player can't join the game unless their inventory is empty

Hello, I am trying my best to attempt to stop players from joining a mini gamemode with their inventories having items inside them.

My method on when the attempts to join the gamemode.

Code:

        else if (args[0].equalsIgnoreCase("join")) {
            if (p.hasPermission("ffa.join")){
                if (!p.getGameMode().equals(GameMode.SURVIVAL)){
                    p.sendMessage(ChatColor.RED + "You must be in survival to join FFA!");
                }
                else if (p.getGameMode().equals(GameMode.SURVIVAL)){
                    if (!p.isEmpty()){
                        p.sendMessage(ChatColor.RED + "Please empty your inventory before joining FFA!");
                    }
                    else if (p.isEmpty() && p.getGameMode().equals(GameMode.SURVIVAL)){
                        this.main.joinGame(p);
                        Bukkit.broadcastMessage(ChatColor.YELLOW + p.getName() + ChatColor.AQUA + " has just joined the FFA game!" + ChatColor.GRAY + " (" + ChatColor.YELLOW + "/ffa join" + ChatColor.GRAY + ")");
                    }
            }
          }
        }

My method for the p.isEmpty()

Code:

  public static boolean isEmpty(Player player) {
      int empty = 0;
      int armors = 0;
      for (ItemStack item : player.getInventory().getContents()) {
              if (item == null || item.getType() == Material.AIR) empty++;
      }
      for (ItemStack armor : player.getInventory().getArmorContents()) {
              if (armor == null || armor.getType() == Material.AIR) armors++;
      }
      return empty == player.getInventory().getContents().length && armors == player.getInventory().getArmorContents().length;
  }

I've tested it in-game, it still lets the player join the mini game with items in their inventory.
Please help me

 

@PerezHD Your using Entity#isEmpty() with checks if a vehicle is empty. You never actually invoked your method.

 

@PerezHD You call p.isEmpty(), not isEmpty(p)...
