After the initial tween finishes, the
0 pixels. The following snippet (edited for brevity) shows the function prototype for the
method:
continueTo()
function continueTo(finish:Number, duration:Number):Void {
/* omitted to save space. */
}
Only two arguments pass to the
the Tween constructor method, as the following snippet shows:
function Tween (obj, prop, func, begin, finish, duration, useSeconds) {
/* omitted to save space. */
}
The five parameters that aren't required by the

begin useSeconds
class. When you call the
type), and
useSeconds
method uses the
continueTo()
specifying a value for the

import mx.transitions.easing.*;
var ball_tween:Object = new Tween(ball_mc, "_x", Regular.easeIn, 0, 300, 3,
true);
ball_tween.onMotionFinished = function() {
ball_tween.continueTo(0, 3);
};
This code moves the
seconds. After the animation finishes, the
calls the
continueTo()
( ) to proceed from its current position and animate for three seconds along the x-axis

to 0 pixels and to use the same easing method. You use the values specified in the call to the
Tween constructor method for any parameters that you don't define in the
method. If you don't specify a duration for the
you specify in the call to the Tween constructor.
Creating animations that run continuously
You can make an animation continue moving back and forth along the x-axis without
stopping. The Tween class accommodates this kind of animation with the aptly named
method. The
yoyo()
