I used this to tween a plane in the direction it's facing, can't tell you if
it will work in 2.5 or not, but give it a go. Something Fabrice pointed me
in the direction in mid 2009, not sure what version away3d was on then but
may work.
//
------------------------------------------------------------------------------------------------
public function overHandler(e:MouseEvent3D):void
{
var plane:Plane = e.target as Plane;
//plane.pushfront = true;
// work out move forward direction by 1000 and tween to that number3d
var target:Number3D = plane.transform.forward;
target.scale(plane.position,-0.2);
target.add(target,plane.position);
plane.pushfront = true;
plane.pushback = false;
var nTargetScale:Number = 1.5;
TweenLite.to(plane,1,
{
x:target.x,
y:target.y,
z:target.z,
scaleX:nTargetScale ,
scaleY:nTargetScale,
scaleZ:nTargetScale
}
);
}
