Shoot Small Fireball Straight?

Trying To Create some Tests when a player shoots a Small Fireball. But i cant seem to get it to Shoot Straight. (It curves slightly)

Code:

                        Player Shooter = (Player) evt.getEntity().getShooter();
                        SmallFireball Fire = (SmallFireball) evt.getEntity();
                        Vector Test = Fire.getDirection()

I tried several things and I cant seem to get the Fireball to shoot straight.

 

thats when you're getting its velocity, to get it to go strait do this

Code:

Player shooter = (Player) evt.getEntity().getShooter();
SmallFireball Fire = (SmallFireball) evt.getEntity();
Vector Test = Fire.getLocation().getDirection();
Test.multiply(2);
Fire.setVelocity(Test);

that will shoot it in a strait line
