Using Tween in AS3

I have just completed migrating a lot of AS2 code to an AS3
ActionScript Project, and have one issue left to solve. When I try
to import anything in the mx.effects package, such as
mx.effects.Tween, I get an error from Flex Builder "1172:
Definition mx.effects:TweenEffect could not be found." I notice
that if I type import mx. the dropdown that provides a list of
values that can be selected, doesn't include effects. While
searching the web I have seen examples that import ms.effects.* so
can anybody tell me how I can get to use the Tween class?

I also have had issues. What's the good word on best way to
do transitions in AS3?
Thanks.

Save motion tween as as3 in flash cc2014

in previous flash i had the ability to save motion tween as as3 and use it an scripting.
i can not find it in flash cc 2014
how can i use motion preset as part of as3 scripting?

i don't know why it was removed, but in general the adobe engineers had to decide which features from the 32bit flash pro (cs) should be added to the 64bit flash pro (cc). and there were time-constraints so the more features carried-over, the long it would take to release cc.
i don't know if it's better to use xml because i've never seen the need to use either feature, ever. in fact, i don't use the flash timeline tweening and i don't use the flash tween class. like many flash professionals, i use a 3rd party library from greensock, tweenlite (usually and lately tweenmax).
and finally yes, cc subscribers can use flash pro cs6: open your cc desktop app>click apps>filters&versions>previous versions>flash pro install>cs6.

Simple tutor for motion tween in AS3

i am searching one simple tutor for motion tween in AS3. Does any body know website ?

Assuming you are creating your tweens using actionscript I would highly recommend using the external animation engine TweenLite, developed by greensock. You can download it and read a tutorial on it here: http://blog.greensock.com/get-started-tweening/
If you are just creating tweens using the timeline then try this one: http://tv.adobe.com/watch/learn-flash-professional-cs4/getting-started-13-creating-motion- tweens/ I've not watched this one in a while but I seem to remember that the tutorials in this series were quite helpful to me.
Hope they help you out!

Timeline like navigation using tween class

I am a beginner, please help!
So I want to create a timeline nav like this site:
http://us.leica-camera.com/photography/m_system/m9/
timeline is a 40 x 40px color filled movie clip that use as the playhead.
featContent is the movie clip that contains the feature content.
I make the timeline controls the feature contents to slide (using tween class) to the next feature. No problem on this, but I can't make the feature to slide when click on the button.
Please shed some lights! Thank you very much!
function loadFeature(node){
      var m = 0;
      this.createEmptyMovieClip("featNav",50);
      this.timeline._xscale = 1;
     this.createEmptyMovieClip("featContent",10);
      this.featNav._x = featNav_x;
      this.featNav._y = featNav_y;
      featl = node.childNodes.length;
           fBtnW = (featNav_w/featl);
           duration = 10*featl;

           moveTimeline.onMotionFinished = function(){
                     moveTimeline.start();
      moveTimeline.addListener(t_listen);

Nevermind, I think I found what I needed. Thanks guys!

How to Load an external swf using loadmovie in AS3

Subject: How to Load an external swf using loadmovie in AS3
In AS3 you use the Loader class to load external swf's and image files. You
should be able to find examples both in the Flash help files and these forums
if you search. If you aren't aware of how to code buttons in AS3, that can be
found as well. In AS3, just about any kind of interction involves the use of
event listeners in combination event handler functions... in the case of a
button rollover an example would be...
btnName.addEventListener(MouseEvent.ROLL_OVER, overHandler);
function overHandler(evt:MouseEvent):void {
// your loading code or whatever

Motion Tweens in AS3

I'm trying to make a screen object(digitB1_mc) move in one of two different directions, depending upon the current cicumstances.
I drew the Motion Tween _B1_12 and saved it as a preset for the first direction.
I drew the Motion Tween _B1_21 and saved it as a preset for the second direction.
Then I tried to find AS3 code to grab one of these two from the presets and apply it to digitB1_mc. Could not find a way to do it.
Then I copied _B1_12 to Actionscript 3.0 code (ie. clipboard) and pasted it into an Actionscript 3.0 function B1_12 and got:
function B1_12() {
import fl.motion.AnimatorFactory;
import fl.motion.MotionBase;
import fl.motion.Motion;
import flash.filters.*;
import flash.geom.Point;
var __motion_digitB1_mc:MotionBase;
if(__motion_digitB1_mc == null) {
    __motion_digitB1_mc = new Motion();
    __motion_digitB1_mc.duration = 11;
    // Call overrideTargetTransform to prevent the scale, skew,
    // or rotation values from being made relative to the target
    // object's original transform.
    // __motion_digitB1_mc.overrideTargetTransform();
    // The following calls to addPropertyArray assign data values
    // for each tweened property. There is one value in the Array
    // for every frame in the tween, or fewer if the last value
    // remains the same for the rest of the frames.
    __motion_digitB1_mc.addPropertyArray("x", [0,7.4116,14.0277,19.6419,23.9742,26.6463,27.1809,25.0619,19.91,11.7411,1]);
    __motion_digitB1_mc.addPropertyArray("y", [0,-14.8969,-30.1606,-45.8179,-61.8789,-78.2953,-94.9161,-111.395,-127.195,-141.658,-154. 35]);
    __motion_digitB1_mc.addPropertyArray("scaleX", [1.000000]);
    __motion_digitB1_mc.addPropertyArray("scaleY", [1.000000]);
    __motion_digitB1_mc.addPropertyArray("skewX", [0]);
    __motion_digitB1_mc.addPropertyArray("skewY", [0]);
    __motion_digitB1_mc.addPropertyArray("rotationConcat", [0,36,72,108,144,180,216,252,288,324,360]);
    __motion_digitB1_mc.addPropertyArray("blendMode", ["normal"]);
    __motion_digitB1_mc.addPropertyArray("cacheAsBitmap", [false]);
    // Create an AnimatorFactory instance, which will manage
    // targets for its corresponding Motion.
    var __animFactory_digitB1_mc:AnimatorFactory = new AnimatorFactory(__motion_digitB1_mc);
    __animFactory_digitB1_mc.transformationPoint = new Point(0.500000, 0.500000);
    // Call the addTarget function on the AnimatorFactory
    // instance to target a DisplayObject with this Motion.
    // The second parameter is the number of times the animation
    // will play - the default value of 0 means it will loop.
    // __animFactory_digitB1_mc.addTarget(<instance name goes here>, 0);
But when I called this function it did nothing at all except increase my swf file size from 3.8 kb to 27.3 kb.
Can anyone suggest a solution that would allow me to swap back and forth between two motions for an object.
Thanks,

The culprit is most likely the garbage collector. If you do
not have any references to your tween object, it will eventually be
destroyed by the garbage collector.
From
Adobe
Flash Quick Start

Note: Consider variable scope when using the Tween class. If
a tween is created in a function, it is important that the
variable's scope exists beyond the function itself. If a tween is
stored to a variable of local scope, ActionScript garbage
collection removes the tween as the function completes, which will
likely be before the tween has even begun.

Loading external swf in array using wildcard in as3?

Hi
I can use the following code to load in a specific swf:
var clips:Array = ["001/001.swf"];
but how do I tell Flash to load whatever file is in the 001 folder without stipulating a specific filename?
Thanks
Shaun

Not possible in Flash Player. Though this is possible in AS3 the API is only supported for AIR runtime and not for FP.
The alternate way is to achieve this using PHP script which you can use in combination with AS3.

Tweens in AS3 Freezing / Sticking

Hi all,
i have a problem with my tweens, usually they are just fine
(i am tween an MC via three tweens x,y and rotation) sometimes
however they simply freeze or stop dead. they dont complete
properly becuase the MOTION_FINISHED event does not trigger.
The swf doesnt freeze as i can pick up the tween from were it
left off. It just seem that Flash "forgets" its doing a tween
Sometimes, only one or two of the tweens will stop, for
example it will get to its y position, but it will stop rotating
and moving along the x axis
its very frustrating, any ideas?
have a look for yourselves here :

Using swf and AS3 on supercomputer

I (might) have an opportunity to run my ActionScript 3 project on a Cray supercomputer in couple of weeks.
How can I be sure that I benefit of the multiple processors an big memory space?
And I need to understand how will I benefit?
Is window="gpu" embed tag all it takes, or should I use Alchemy and different ASC?
That gpu -tag is said to give benefits only in some occasions, would this be the occasion?
Maybe there is readymade versions of Flash-Player that will use multiprocessor?
Filesize is below 100kt, but...
My demo is huge fractal with graphics in several (hundreds) nodes, and it can be made even bigger...
I will also use real time generated sounds in background.
Mac mini is already having trouble with it, it would be interesting to see how supercomputer will manage.
Any information?

AS2 and AS3 swfs cannot exist in the same Flash Player
virtual machine - each Flash Player instance (version 9 and
greater) create different address spaces/virtual machines because
the requirements of AS3 and AS2 are so different.

Using AlivePDF with AS3

Hi, I'm somewhat new to AS3 and programming. I'm trying to use the AlivePDF library to export text from a text editor created in AS3 into a PDF. Can anyone link me to documentation or a tutorial that can help teach me how to integrate it into a normal AS3 file? I have no idea how to use the library and the only documentation I've seen for it is how to use it in Flex/Air, which is not what I'm looking for.
Thanks!

Last year, I did a project that used AlivePDF. I found that there wasn't as much tutorial content on the Web as I would have liked. For folks that are new(er) to AS3 - it is lacking enough in Flash tutorials to make it "kinda out of reach" without struggling. Even for myself, I wished there were more simple, but extensive, examples to cull from.
Like you, I kept getting search hits showing me a small handful of Flex apps that used it, but I was able to sift through a few things, including the website that provides the API for us. So this is most likely not going to get you what you want - it was a little bit of a slow start for me, and I just had to "grow" from the small examples I found on the main website, and look at the API documentation...and then put in the time to try my own simple tests.So, I can really only suggest that you start small, understand the basics of AlivePDF, and work from what you have success with.
You've probably been here, but most of what I learned came from the various pages of th main AlivePDF website:
http://alivepdf.bytearray.org/
The link to the API documentation:
http://alivepdf.bytearray.org/alivepdf-asdoc/
there's a Google Wiki, with other API notes:

How to add fast forward - rewind functionality using flvplayback in as3

hello,
i am using flvplayback (dynamically add from as3), now to add fastforward - rewind functionality in it.
Thanks,
Vishal Parekh

The docs say the inBufferSeek is intended for "Flash Media Server 3.5.3 and Flash Player 10.1" or higher and does not work in AIR3.0 for iOS. Do you meet those requirements? They call that protocol RTFMP.
The doc also explains that when inBufferSeek=true, and you seek() or step(), an event is dispatched if it was successful. You should see if these events fire.
From the docs:
When inBufferSeek=true and a call to NetStream.seek() is successful, the NetStatusEvent info.description property contains the string "client-inBufferSeek".
When a call to NetStream.step() is successful, the NetStatusEvent info.code property contains the string "NetStream.Step.Notify".
If you don't see those events, you know you have an issue.

Using levels in AS3

Hey, I'm trying to do a very simple thing in AS3 and it's not working
I have 2 movieclips, A and B. A have some animation and B have a single frame with a code. I want to use this code to play the animation in movieclip A.
When using AS2, i just write in the first frame of B, _root.A,play() or _level0.A.play()
What should I do in AS3 to achieve this. I attached the file, can anyone do the code for me and I can understand it by myself. Thanks

In this case do you really need to cast root as a MovieClip? I'm sure you would if you tried this: MovieClip(root).play(); But in this case you are trying to access the play method of A not root.
The reason for the casting thing (which I regard as a ghastly and completely bollocksed-up) is that in may cases parent or root could reference any number of items that are all decendants of DisplayObject so the property returns the item as a DisplayObject, which doesn't have the timeline control methods of the MovieClip class. DisplayObject is the ancestor from which all the things we can see spring.
As a design decision it might have been worse that parent or root returned a Sprite some times other times a Stage others a MovieClip and so on. Not saying that there isn't a better solution, but this is the solution we have...

Advanced Scrolling Animation using Tween Lite

Hey folks. I'll try to be as concise as possible.
Imagine a res. of about 320 x 480 for a Flash file in which art is displayed, but at the bottom of this .FLA there are 5 icons, 2 inside the white space and 3 on the grey space. What I'm trying to achieve is that if the mouse hovers near the bottom right corner of the screen, the 2 icons in the white space, get shifted left, allowing for the icons in the grey space to move left as well, taking up the palce of the icons in the white space. I'm basically trying to implement a scrolling animation. Let's say in the bottom right and bottom left of this screen I have 2 invisible smaller screens that can listen for the MOUSE_OVER event, then I could perform the following code which is my current implementation:
// Showing implementation of only bottom right invisible screen, bottom left invisible screen
// is almost identical except when mouse hovers it the icons should all shift right
brScreen.addEventListener(MouseEvent.MOUSE_OVER, mouseOver);
brScreen.addEventListener(MouseEvent.ROLL_OVER, rollOver);
public function mouseOver(me:MouseEvent):void
     var iconPosition:uint;
     // All 5 icons on bottom of page are in array called myArray
     for(int i:uint = 0; i <myArray.length; i++)
          var currentIcon:DisplayObjectContainer = myArray[i];
          iconPosition = currentIcon.x; // Only the x position of the icons change when scrolling occurs
          TweenLite.to(currentIcon, 2, {x:iconPosition - 50, y: 450, ease:Quart.easeIn}); // Assume libraries are imported
          // y value of icon never changes since only side-to-side scroll, 450 is an arbitrary value
public function rollOut(me:MouseEvent):void
     brScreen.removeEventListener(MouseEvent.MOUSE_OVER, mouseOver);
The desired behaviour is that as the mouse is hovered over near the bottom right screen, the icons will continue scrolling but as soon as the mouse is hovered off elsewhere, the side-to-side scrolling stops. The issue is that when I hover my mouse near the bottom right screen, all icons get shifted left only once, it seems as if the MOUSE_OVER event isn't propagating while I'm hovering over the bottom right portion of the screen, additionally when I hover my mouse elsewhere and and then re-hover the bottom right portion of screen, all icons only get shifted to the left once. I want it to continuously shift all icons to the left as long as my mouse remains hovered above the bottom right portion of the screen.
If you have a hard time understanding what my desired behaviour is, here is a youtube vid., check at 25 - 40 seconds or so when he starts manipulating the icons at the bottom of the screen, instead of using fingers however for touch screen, I'm going to use a mouse since this is a Flash app. Any help is appreciated.
http://www.youtube.com/watch?v=EGy7Q9vPMdc

No, you cannot make multiple eases on the same property in the same tween. But you can have a separate ease for each property (x and y are different properties). You can, however, create a new tween from point b to c, after point a to b and adjust your ease on that.

Tweening in AS3

I was wondering if anyone could explain me the functionality of the Tweening class in conjunction with e.g. Linear.easeNone function - especially the parameters in the Linear.easeNone function. They read T, B, C, D, where T is "current time", B should be "initial value", C (i suspect) should be "final value" and D should be "duration".
However calling something like this
var value:Number=Linear.easeNone(1,1,0,3);
gives me
1
where I expect it to be 0.666666 (i.e. 2/3 as this is a linear interpolation).
The question: What do the parameters T,B,C,D exactly mean and how am I supposed to use them in to get the correct result?
Thanks for a reply
Tom

Linear.easeNone (t:Number, b:Number, c:Number, d:Number):Number {
return c*t/d + b;
t is the time parameter and varies from 0 to 1.
b is the inital value and corresponds to t=0
d is the duration
c/d is the rate of change or: c = end - b, where end corresponds to t=1
