Thank you so much for this string of tutorials. You have helped me so much!

thanks for the tutorial

I have two tweens; one moving an object 30px down, and the other to move the object up 30px.

I have used your code above to start tween 2, after tween 1 has completed.

How would I go about starting tween 1 again after tween 2 has finished as to create a continuous loop of tweens.

I Found that this worked

[as]

function moveMouth(){
var randomNum:Number = Math.random()*5 + 5;
Tweener.addTween(myTiger.myHead_mc.myMouth_mc, {y: 30, time: 3, delay: randomNum, transition:”easeOut”});
Tweener.addTween(myTiger.myHead_mc.myMouth_mc, {y: 0, time: 3, delay: 3+randomNum, transition:”easeOut”, onComplete:moveMouth});
}
moveMouth();

[/as]

Another way you might do this would be to use the TweenEvent.MOTION_CHANGE then input logic to check the time, position, or other Tween attribute to determine when to start your next Tween.

It seems this would be more burdensome on the processing, but it gives you direct control of your next tween in terms of the original one, which can be very useful.

Try This

function tween1():void {
var tweenY1:Tween = new Tween(instanceName, “y”, None.easeNone, 0, 30, 3, true);
tweenY1.addEventListener(TweenEvent.MOTION_FINISH, tween2);
}

function tween2():void {
var tweenY2:Tween = new Tween(instanceName2, “y”, None.easeNone, 30, 0, 3, true);
tweenY2.addEventListener(TweenEvent.MOTION_FINISH, tween1);
}

//Warning:infinite loops can cause problems

sorry nevermind that doesn’t work

it might be easier to just make a timeline tween where it goes down 30 then up 30 and just loops inside a movieClip

i finally found this at

http://www.republicofcode.com/tutorials/flash/as3tweenclass/

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

var myTween = new Tween(my_mc, “x”, Strong.easeInOut, 100,300, 1, true);

myTween.addEventListener(TweenEvent.MOTION_FINISH, onFinish);
function onFinish(e:TweenEvent):void {
myTween.yoyo();
}

this code will loop my_mc forever

Hello. I have the next situation: I need a logo to fade out and then fade in again every 5 seconds on an infinite loop. (during these 5 seconds it has to stay on alpha=1). I already tried this:

var timer_logo:Timer = new Timer(5000,1);
timer_logo.addEventListener(TimerEvent.TIMER,f_logo_out);
timer_logo.start();

function f_logo_out(event:TimerEvent):void{
var logo_fade_out:Tween = new Tween(logo_inside,”alpha”,Regular.easeInOut,1,0.3,1,true);
logo_fade_out.addEventListener(TweenEvent.MOTION_FINISH,f_logo_in);
function f_logo_in(event:TweenEvent):void{
var logo_fade_in:Tween = new Tween(logo_inside,”alpha”,Regular.easeInOut,0.3,1,1,true);
logo_fade_out.removeEventListener(TweenEvent.MOTION_FINISH,f_logo_in);
logo_fade_in.addEventListener(TweenEvent.MOTION_FINISH,f_logo_x);
function f_logo_x(event:TweenEvent):void{
timer_logo.start();
logo_fade_in.removeEventListener(TweenEvent.MOTION_FINISH,f_logo_x);
}
}
}

When I export the movie it works, but if I live it on playing eventually something goes wrong and it stops. What should I do?

Same problem! I used your method for 8 boxes to do fade in and fade out one after the other, sometimes work, sometimes not, the animation is stuck at some point. Flash can’t handle this? or I have done something wrong?!

@ zedia.net
Thanks zedia. Thank you for the quick reply.
I will try TweenLite tonight, it looks very promising.
But I am still not sure what is wrong with the Tween class, if it is the performance problem that causes the animation stop and goes wrong , I am really disappointed with Adobe….

Code gives following error. Works fine if I dont try to remove the second listner. I thin because the varible “myTweenAlpha1″ is not defined out side the function but I dont know how to define with enacting the the tween. Any help would be aprreciated.

Thanks

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

var myTweenAlpha0:Tween = new Tween(bloc1, “alpha”, Strong.easeOut, 1, 0, .75, true);
myTweenAlpha0.addEventListener(TweenEvent.MOTION_FINISH, doNextTween1);

function doNextTween1(e:TweenEvent):void {
var myTweenAlpha1:Tween = new Tween(bloc2, “alpha”, Strong.easeOut, 1, 0, .75, true);
myTweenAlpha0.removeEventListener(TweenEvent.MOTION_FINISH, doNextTween1);
myTweenAlpha1.addEventListener(TweenEvent.MOTION_FINISH, doNextTween2);
}

function doNextTween2(e:TweenEvent):void {
var myTweenAlpha2:Tween = new Tween(bloc3, “alpha”, Strong.easeOut, 1, 0, .75, true);
myTweenAlpha1.removeEventListener(TweenEvent.MOTION_FINISH, doNextTween2);
myTweenAlpha2.addEventListener(TweenEvent.MOTION_FINISH, doNextTween3);
}

function doNextTween3(e:TweenEvent):void {
var myTweenAlpha3:Tween = new Tween(bloc4, “alpha”, Strong.easeOut, 1, 0, .75, true);
}

1120: Access of undefined property myTweenAlpha1.

Thank you!!!!!!
been searching all day for an easy to understand and basic example of how to do this!

Thanks for the great tutorial! Very clear and informative.

Hi,

i am just beginner in flash ac3. I need to know that when i press a button then below script works in that button. and when i press another button… first page will be gone same way. Please answer my question. I need know it very much.

import fl.transitions.Tween;
import fl.transitions.easing.*;

var myTween:Tween = new Tween(page, “x”, Strong.easeOut, 0 , 200, 2, true);
