Check when a player equips armor

I know this has been discussed before but I couldnt find an answer that helps me. I want to give a player invisibilty when he equips boots but i dont know how to do that. I already tried various things but nothing worked. I just need a simple solution on how to do this.


Please excuse my bad spelling and grammar im not very good at english.

 

You have to handle InventoryClickEvent and PlayerInteractEvent for equipping through clicking the inventory and right clicking boots in the hotbar respectively.
Since this is slightly complex, i'll spoonfeed you this to get you started.

PHP:

List<Material> bootsMaterialList = new ArrayList<>();
// ^ fill this with all Materials for every type of boots

public void onEquipEvent(InventoryClickEvent event) {
    if (!(event.getWhoClicked() instanceof Player))
        return;

    Player player = (Player) event.getWhoClicked();

    ItemStack eventItem = event.getCurrentItem();
    if (eventItem == null || !bootsMaterialList.contains(eventItem.getType())
        return;

    Runnable task = new Runnable() {
        @Override
        public void run() {
            ItemStack boots = player.getInventory().getBoots();
            if (boots == eventItem) {
                // player successfully equipped boots
            }
        }
    };
  
    Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, task, 1);
}

It comes from one of my plugins, with slight changes. I did not test this.
Good luck.

 

A much easier way vs rolling your own is to use Arnuh's excellent ArmorEquipEvent.
