Tag Plugin Help (EntityDamageByEntityEvent)

So 'im trying to make a simple tag plugin. But i'm having trouble with the tag part. There are no errors coming up in the console. So here is the code that I have. Any help is very appreciated!

Code:

    @EventHandler
    public void ontag(EntityDamageByEntityEvent event){
        Entity target = event.getEntity();
        Entity player = event.getDamager();
        if(target instanceof Player){
        if(player instanceof Player){   
        if(tag.contains((Player)player)){
            ((Player)player).getInventory().remove(getCustomItem(Items.tag));
            ((Player)player).getInventory().remove(getCustomItem(Items.helm));
            ((Player)target).getInventory().setItemInHand(getCustomItem(Items.tag));
            tag.remove((Player)player);
            tag.add((Player) target);
        for(Player online : Bukkit.getOnlinePlayers()){
            if(!(toggle.contains(online))){
                online.sendMessage(ChatColor.GRAY + "[" + ChatColor.GOLD + "Tag" + ChatColor.GRAY + "]: " + ChatColor.RED + ((Player)target).getName() + " is it!");
   
        }else if(target instanceof Player){
            if(player instanceof Player){
                if(toggle.contains(target)){
                    ((Player) player).sendMessage(ChatColor.GRAY + "[" + ChatColor.GOLD + "Tag" + ChatColor.GRAY + "]: " + ChatColor.RED + ((Player)target).getName() + " isn't playing tag!");
                }
            }
        }
        }
       
        }
        }       
    }
    }
        

 

Zolltar did you register events?

 

Yes, and I have other events in the plugin that are functioning fine.

 

If you did register the events like stated before then add debug lines to every if statement. See what is not firing, and try to figure out why!

 

And here's where I let my signature do the work...
