Here is an example for the beginning.

-- BetweenAS3Exam1.as class --

package exam1{
 import flash.display.Sprite;
 import flash.events.Event;
 
 import mx.core.Application;
 
 import org.libspark.betweenas3.BetweenAS3;
 import org.libspark.betweenas3.easing.*;
 import org.libspark.betweenas3.events.TweenEvent;
 import org.libspark.betweenas3.tweens.ITween;

 public class BetweenAS3Exam1 extends Sprite
 {
  public var box:Sprite;
  private var t:ITween;
  public function BetweenAS3Exam1()
  {
   this.box = new Sprite();
   this.box.graphics.beginFill(0x000000);
   this.box.graphics.drawCircle(10, 10, 5);
   this.box.graphics.endFill();
   addChild(this.box);
   this.t = BetweenAS3.tween(this.box, {x:100, y:100}, {x:0, y:0}, 0.6, Bounce.easeOut);
   this.t.play();

  }
  
  public function goRight():void{
   if(this.t!=null && this.t.isPlaying)
    this.removeTween();
    
   this.t = BetweenAS3.tween(this.box, {$x:50}, {$x:0},.5); 
   this.t.play();
  }
  
  public function goLeft():void{
   if(this.t!=null && this.t.isPlaying)
    this.removeTween();
    
   this.t = BetweenAS3.tween(this.box, {$x:-50}, {$x:0},.5); 
   this.t.play();
  }
  
  public function goUp():void{
   if(this.t!=null && this.t.isPlaying)
    this.removeTween();
    
   this.t = BetweenAS3.tween(this.box, {$y:-50}, {$y:0},.5); 
   this.t.play();
  }
  
  public function goDown():void{
   if(this.t!=null && this.t.isPlaying)
    this.removeTween();
    
   this.t = BetweenAS3.tween(this.box, {$y:50}, {$y:0},.5); 
   this.t.play();
  }
  
  private function removeTween():void{
   this.t.stop();
   this.t = null;
  }
 }
}
