ThrowObject oddity

I am using throwObject to have the enemy throw an item toward me, however, it always throws in the opposite way and there are some oddities. I don't have a full understanding of throwObject, why does it always throw in the opposite direction away from me?
thanks


function ShapeBase::throwObject(%this,%obj)
{
// Throw the given object in the direction the shape is looking.
// The force value is hardcoded according to the current default
// object mass and mission gravity (20m/s^2).
%throwForce = %this.throwForce;
if (!%throwForce)
%throwForce = 20;

// Start with the shape's eye vector...
%eye = %this.getEyeVector();
%vec = vectorScale(%eye, %throwForce);

// Add a vertical component to give the object a better arc
%verticalForce = %throwForce / 2;
%dot = vectorDot("0 0 1",%eye);
if (%dot < 0)
%dot = -%dot;
%vec = vectorAdd(%vec,vectorScale("0 0 " @ %verticalForce,1-%dot));

// Add the shape's velocity
%vec = vectorAdd(%vec,%this.getVelocity());

// Set the object's position and initial velocity
%pos = getBoxCenter(%this.getWorldBox());
%obj.setTransform(%pos);
%obj.applyImpulse(%pos,%vec);
error("applyImpuse to "@%pos@", "@%vec);
// Since the object is thrown from the center of the
// shape, the object needs to avoid colliding with it's
// thrower.
%obj.setCollisionTimeout(%this);
