timers and fake items

hello!
im trying to make plugin that will let you shoot item (with custom name so its wont be every item..)
and make the item explode with effect after X ticks... this is the code that i have at the moment :

Code:java

 
@EventHandler
  public void onShoot(EntityShootBowEvent e) {
    if (((e.getEntity() instanceof Player)) &&
      (e.getBow().hasItemMeta()) &&
      (e.getBow().getItemMeta().getDisplayName().equals(ChatColor.RESET + "Spray Painter"))){
        e.setCancelled(true);
    Player player = (Player)e.getEntity();
    Location loc = player.getLocation();
    Location eyeloc = player.getEyeLocation();
    Entity pro = e.getProjectile();
            Vector v = pro.getVelocity();
            World world = player.getWorld();
            Entity item = world.dropItemNaturally(eyeloc, new ItemStack(pop));
            item.setVelocity(v.multiply(0.2));
    player.getWorld().playSound(loc, Sound.STEP_WOOL, 10.0F, 0.8F);
    this.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
        public void run() {
                }
 
    }, 40L);
}     
}
}   
 

now, for the questions!
1. how do i make the item play effect after X ticks
2. how do i make the item despawn after X ticks
3. how can i disable the item pickup event? (only for item named pop...)
i tried with player pick item event but it didnt work... :/
i have set all the "pop" and Spray Painter items alredy
thx !

here you go:

Code:java

@EventHandler
    public void entityShootBow(EntityShootBowEvent e){
        if(e.getEntity() instanceof Player){
            Player p = (Player)e.getEntity();
            if(p.getItemInHand() != null){
                if(p.getItemInHand().getItemMeta() != null){
                    if(p.getItemInHand().getItemMeta().getDisplayName() != null){
                        if(p.getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase("whatever")){
                            final Item i = p.getWorld().dropItem(p.getLocation().add(0,2,0), p.getItemInHand());//spawn it a bit higher than the arrow
                            i.setPickupDelay(9999);//disable pickup
                            i.setVelocity(e.getProjectile().getVelocity());
                            e.setProjectile(i);
                            new BukkitRunnable() {
                                int c = 30; //or how many seconds you'd like to wait
                                public void run() {
                                    if(c != 0){
                                        c--;
                                    }else{
                                        //do whatever you want to do after x seconds has passed.
                                        i.getWorld().playSound(i.getLocation(), Sound.STEP_WOOL, 1, 1);
                                        i.remove(); // despawns it
                                        this.cancel();
                                    }
                                }
                            }.runTaskTimer(this, 9, 9);
                        }
                    }
                }
            }
        }
    }
