// Let’s start by importing libraries
import fl.transitions.Tween;
import fl.transitions.easing.*;
// This will import all eases

//Motion Tween events is a library that
//has to be imported
import fl.transitions.TweenEvent;
// Now we can start coding

var xTween : Tween;
// This is the variable that will hold the Tween
// in our case the “Tween” is the horizontal motion
// on stage

// This starts the animation on load
xTween = new Tween(boat_mc,”x”,None.easeNone, 10,450,7,true);

// boat_mc is the name of the symbol instance
// x is the tween type, this means horizontal movement
// none is the bounce and ease
// starts at coordinate 10 – that is the left side of the stage
//and finishes at 450, taking all together 7 seconds.
// the true states that we are counting seconds, not milliseconds…

// we have currently 3 buttons on stage
//Event Listeners – this will set the compiler
// waiting for button clicks
play_btn.addEventListener(MouseEvent.CLICK, playTween);
stop_btn.addEventListener(MouseEvent.CLICK, stopTween);
rewind_btn.addEventListener(MouseEvent.CLICK, rewindTween);

// Let’s add an event listener to the TWEEN!
xTween.addEventListener(TweenEvent.MOTION_FINISH, motionFinish);
//When the tween is finished will fire the motionFinish function

//Functions
//Play
function playTween (event:MouseEvent):void
{xTween.resume();}

//Stop
function stopTween (event:MouseEvent):void
{xTween.stop();}

//Rewind
function rewindTween (event:MouseEvent):void
{xTween.rewind();}

// This will stop the animation
// on the very beginning after it started
xTween.stop();

function motionFinish(event:TweenEvent):void
{

xTween.yoyo();
//The yoyo method will play back and foward
