How do I script a fireball?

I am making a Naruto Shippuden game and I don't know how to script the Jutsus.Any help or refferences on this?

Use Instance.new("Ball") to create a ball or whatever it looks like, then change it's Anchored to false and CanCollide to false, then make it's Velocity+Direction were the character is pointing.

Do what micke said but maybe also add the "Fire" object inside ball to give the fireball look.
