Adjusting spawned Fireball speed

I have this code which effectively spawns fireballs and shoots them at a target given a source. Problem is that the fireballs are extremely fast and cannot be dodged at all. Try though I might, i've had no luck via combinations of multiply/normalize/etc being able to adjust the speed at which the buggers fly. Anyone had any success with this?

Here's the code:

Code:java

void shootFireball(Player p) {
Vector lookat = p.getLocation().toVector().subtract(fireballSource.toVector()).normalize();
 
Fireball fireball = world.spawn(fireballSource, Fireball.class);
fireball.setDirection(lookat.normalize());
}

Multiply the vector by 0.9 or something.

That has no effect.

 

Try multiplying it by more that 1

 

Cryptite
Why not use setVelocity?

Multiplying by more than 1 also doesn't seem to effect the speed... :/

No luck. Seems as though using setVelocity without setDirection and the fireball doesn't shoot at all.
