Snowball w/ Particles & Travel Distance

Hey Bukkit,

I have this simple code

Code:

Snowball snowball = p.getWorld().spawn(p.getEyeLocation(), Snowball.class);
                            snowball.setVelocity(p.getLocation().getDirection().multiply(5));
                            snowball.setShooter(p);

To shoot a snowbal and speed it up now I only want to add particles to the snowball when it is going trough the air also I want to at something so I can set it can travel maxium 5 blocks in the air and then the snowball gets removed and if needed I can execute some code at the snowball at that place before it gets removed, How to?

 

Make a repeating task (BukkitRunnable) and store the start location. Then display the particles at the snowballs location. When the startLocation.distance(snowballLocation) is greater than 5, cancel();
Here is a BukkitRunnable:

Code:

new BukkitRunnable() {
public void run() {
//Code
}
}.runTaskTimer(this, 0, 5);

 

Thanks but the Runnable wasnt that hard but more a particle effect and the distance stuff but ill see
