Solved Inventory Help

Hello, I am developing a plugin, and testing out some sign stuff. When a player clicks a sign, it should fill up their entire hotbar with shovels, but it only fills up one slot. But when the player relogs to the server, all the slots are filled.
Here is my code:

Code:java

 public void devTest() {
List<String> spadeLores = new ArrayList<String>();
spadeLores.add("Spleef!!");
String spadeName = "The Spleefing Machine";
ItemStack spade = new ItemStack(Material.DIAMOND_SPADE);
ItemMeta spadeMeta = spade.getItemMeta();
spadeMeta.setDisplayName(spadeName);
spadeMeta.setLore(spadeLores);
spade.setItemMeta(spadeMeta);
spade.addUnsafeEnchantment(Enchantment.DIG_SPEED, 10);
p2.getInventory().clear();
 
p2.getInventory().setHeldItemSlot(0);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(1);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(2);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(3);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(4);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(5);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(6);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(7);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(8);
p2.getInventory().addItem(spade);
p2.getInventory().setHeldItemSlot(4);
p2.getInventory().addItem(spade);
}

P.S.
This code is activated when the sign is clicked.

 

Try checking this method out, rather than using addItem(), and setHeldItemSlot(), though I don't think it's that big of a deal.

Code:java

p2.getInventory().setItem(0, spade);

Make sure to call Player#updateInventory() when you're done

Thank you. I had a feeling I had to update the inventory, but I didn't know how to. It worked, and now you get 9 Spleefing Machines!
