Solved Mob player detection

How can i increase the mob detection of a giant?

Code:

 if (!(sender instanceof Player)) {
                sender.sendMessage(ChatColor.RED + "You cannot summon a giant!");
                return true;
        }
       
        Player p = (Player) sender;
       
        if (cmd.getName().equalsIgnoreCase("giant")) {                   
                if (!p.hasPermission("admin.giant")){
                    p.sendMessage(ChatColor.RED + "You don't have permsission for this!");
                }else{
                    Giant g = (Giant) p.getWorld().spawnEntity(p.getLocation(),EntityType.GIANT);
                    g.addPotionEffect(new PotionEffect(PotionEffectType.SPEED,Integer.MAX_VALUE,3));
                    g.addPotionEffect(new PotionEffect(PotionEffectType.WEAKNESS,Integer.MAX_VALUE,3));
 
                    g.setCanPickupItems(false);
                    g.setMaxHealth(50.0);
                    g.setTarget(p);
                }
                }
        return false;
    }
    }
