Solved Add air/empty slot to player's inventory?

I tried player.addItem(new ItemStack(Material.AIR, 1)), but it doesn't add inventory an empty slot.. It just like nothing happens with this code.

What should I do? I want the first slot to be a block, third slot to be a sword. How to skip second block if I can't set second slot to air?

Thanks

 

Just don't do anything to the second slot..? addItem won't do it, you need to set the specific slot numbers.

 

so you want a permanently empty slot?
just use listeners to stop stuff going in.

 

nope, i mean addItem will add item according to your slots; I want to skip some of the slots.

 

Ohh, right i get it.
you can add items in an array for the slots i believe.

 

you need to use null for empty slot

 

It will throws NullPointerException..

 

No it won't. use null instead of the itemstack

 

Error: The validated object is null

 

you need to set, not add

 

Code:java

@Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if(commandLabel.equalsIgnoreCase("FillInventory")){
            if(sender instanceof Player == false){
                sender.sendMessage("Command Must Be Used As A Player!");
            }else{
                if(args.length == 0){
                    Player player = (Player) sender;
                    PlayerInventory inv = player.getInventory();
                    inv.setItem(1, new ItemStack(null, 1)); //1 being the slot and null leaving the slot empty
                    //doing it this way means you dont have to set it to null you can just set the slots that you want
                }
            }
        }
        return false;
    }

 

Still, NullPointerException..

 

inv.setItem(1, null);
