You see this code? It's working with the damage on zombies but I get an error if I hit the egg on a player. It says "CraftPlayer Cannot be cast to org.bukkit.entity.zombie" How do I fix this?

	@EventHandler
	public void Egg(EntityDamageByEntityEvent e) {
		if ((e.getDamager() instanceof org.bukkit.entity.Egg)) {
			Zombie ent = (Zombie) e.getEntity();
			if (ent instanceof Zombie) {
				e.setDamage(10);

			}
		}
	}
