Throwing Item as projectile - Damage

Hello,

I want to make throwing like "knives" :

So i just made this code

Code:java

 
    @EventHandler
    public void onInteract(PlayerInteractEvent e) {
        Player p = e.getPlayer();
        ItemStack i = p.getItemInHand();
 
        if (i.getType() == Material.IRON_SWORD && i != null) {
            if (e.getAction() == Action.RIGHT_CLICK_AIR) {
                p.getInventory().remove(i);
                Item dropped = p.getWorld().dropItem(p.getLocation(), i);
                if (p.isSneaking()) {
                    dropped.setVelocity(p.getLocation().getDirection().normalize().multiply(0.75));
                } else if (p.isSprinting()) {
                    dropped.setVelocity(p.getLocation().getDirection().normalize().multiply(1.75));
                } else {
                    dropped.setVelocity(p.getLocation().getDirection().normalize().multiply(1.25));
                }
            }
        } else {
            return;
        }
    }
 

This works properly, and now to my question:


How I can i do Damage on hitting an Entity, if i've thrown the "knife".

 

@FlaveDrake

1. Create a BukkitRunnable. Make it so it runs every couple of ticks.
2. Inside the task, check if there are any nearby entities within a 1 block radius.
3. If so, damage them and remove the dropped item
4. If not, check if the item is on the ground, and if so, cancel the task.
