Armor Equip Event?

Im making this plugin and I can't seem to get the armor equiped. I've tried e.getCurrentItem and such and none of it worked. Please help me, sorry for the short description.

Code:

@EventHandler
    public void onHorseMask(InventoryClickEvent e) {

        Player p = (Player) e.getWhoClicked();

        ItemStack skull = new ItemStack(Material.SKULL_ITEM);
        SkullMeta sm = (SkullMeta) skull.getItemMeta();
        skull.setDurability((short) 3);
        sm.setOwner("gavertoso");
        sm.setDisplayName(ChatColor.AQUA + "Horse Mask " + ChatColor.GOLD + "IV");
        skull.setItemMeta(sm);

        if (e.getSlotType() == SlotType.ARMOR) {
            if (p.getInventory().getHelmet() == null) {
                if (e.getCurrentItem() == skull) {

                    p.closeInventory();
                    p.sendMessage(ChatColor.GREEN + "You have equiped a " + sm.getDisplayName());
                    Bukkit.broadcastMessage(ChatColor.RED + "Added Meta - Works");
                    p.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, 5000000, 4));
                } else {
                    p.sendMessage(ChatColor.RED + "EEEEEEE");
                    return;

 

1. use .equals() instead of ==.
== isn't comparing the values of the object
2. If you want to call something when you're equipping armor, use something like InventoryDragEvent (answer to your topic of post)
3. If you want to equip a helmet use

Code:

PlayerInventory pi;
ItemStack helmet;


pi.setHelmet(helmet);
