ActionScript 2.0 :: Variables "scoped" To The Main Timeline?
Jan 2, 2007
I am going through the tutorial in the Flash MX 2004 Bible, Chap 33 "Creating A Game in Flash" when on page 1000, the author states in a side note that "We don't use the var keyword here because we want the style variables to be scoped to the main timeline of the movie. In this way, we can access the styles from various functions throughout the game."I've noticed what I thought were two ways to declare variables:
1. "someVar:Type = someThing"
2. "var somVar:Type = someThing"
I never knew what the difference was between these two methods.

I built my website on the main timeline with a fade in animation...stop(on the page) and a fade out animation. At the end of this fade out animation i would like it to call upon a variable to know what page to go to next.I am trying to tell my main timeline to gotoAndPlay a frame based off of a variable within a movieclip(about_mc this movieclip contains another movieclip which acts like a button(factsheet_mc)) that i have set in my main timeline.I set the variable with:
var buttonFrame; in the first frame of the main timeline
then within my movieclip i have another movieclip which tells my main timeline to play the out fade and remember a variable:
this.onRelease = function(){ --------"this" meaning the movieclip factsheet_mc------------ [code]........

I've got a problem using variables in my Flash project. I've got a variable called "count" decelerate in a layer of my main timeline.
Like this: _global.count=0;
In my movieclip I want to set that variable from 0 to 1.
For do that I wrote in a code layer of my mc: _global.count=1;
Now... When I perform a new action the variables count return to 0.
It's seem that Flash reset all variables.

Is there a way to access variables on the main timeline in Flash other than MovieClip(root).myVar ? The problem I am having is that I have a movie clip that uses several main timeline variables, but when I instantiate it, it throws a 1009 type error (cannot access property of null object reference). My understanding of whats going on (and please correct me if I am wrong) is that when instantiated it runs the code on the first frame of the movieclip. However, it is not added to display list yet, so it does not have a root. Thus, all the MovieClip(root).myVar lines do not have a root to look at. Does anyone know of a way around this?

I have movieclip that act as a container for a short animation. This animation has a script that repeat the movements until it's greater than a variable. But I wonder if it's possible to use this movieclip on several places on the timeline and have a several variables with different max number of movements that control the script inside the movieclip container? I have tested, but it seems like the value from the variable at the main timeline don't reach the script in the container!?

Let us say we have a movieclip "mc1" on the stage. We also have another movieclip "mc2" inside mc1. We have declared a variable, say, var number1:Number=5 on the first frame of the main timeline. Now we go inside mc1 and then inside mc2 and write some code on its first frame. Is there any way to use the variable number1 over here? Can properties of mc1 be altered using the code written here? In AS2, it could be done using the "_parent" command, but it doesn't seem to work in AS3. (when we use parent and try accessing a property, it says that it is possibly undefined)

I have some main time line variables I need to access and manipulate from inside a movieclip timeline. However, when I try to subtract from a global variable, one that's declared on the main timeline on frame 1 outside of a function/whatever, it says:Symbol 'lemon_cup', Layer 'actions', Frame 1, Line 54 1120: Access of undefined property lemons1.

I have a file comprised of 1 scene and two movie clips. The clips are instanced into the Main Timeline and occupy Frames 1 and 2 respectively.MovieClip1 is an animation that has navigation buttons that appear at the end of the clip. I'm trying to get mouse click navigation to make Frame 2 on the Main Timeline active.
Here is what I'm trying but it is not working:
btExplore.addEventListener(MouseEvent.CLICK, ExploreClick);
function ExploreClick (evt:MouseEvent):void {
gotoAndStop(2);
}
this takes the animation to Frame 2 of the Movie Clip Timeline not Frame 2 the Main Timeline.

I'm having some problem with the workflow of flash.I make web banners everyday att my work att it is important to me to have the banners easy structured so I can copy effects, tweens and symbols to a new banner. I have Flash CS3 pro.I always start by making a symbols. And then in the symbols own timeline I make the animation or effect.
The big problem I'm having is when I have the main (scene1) timeline with many frames, and then have symbols on that timeline, with it's own timeline with some frames. The frames in the symbol timeline is okey, but at the main timeline the frames is too short or too long so the animation of the symbol cuts of early or it plays more than one time (too many frames).
How do I calculate how long a symbols timeline should be so It maches the main timeline?What happens to me is that I always have to adjust the symbols timeline and the main timeline, and this I have to do many times.

I have a main.fla which has 3 movieclips inside it. All 3 mc's have timelines that run 40 frames. The main.fla timeline has each mc instance on a frame. mc_1 is on frame 1 mc_2 is on frame 40 mc_3 is on frame 81 as the main timeline plays the clips each one fades to the other. I need to know how to target this scenerio after mc_3 plays I need to have a goToAndplay (20) set up so the animation inside mc_1 starts playing (frame 20) of mc_1.

I have a movieclip on the scene. I also have a button on the scene and when I press the button I want to send a variable-value to the movieclip. I have a variable set in the actual frame on the main-timeline but the movieclip doesn't catch that, when traced I get undefined. Can I send a value from the main-timeline to a moviclips timeline?

I have created a number of Movieclips as part of my Navbar such as About Us, Contact etc. I'm using setInterval to send them to a function that springs them open one after another using the tween class. The they are dynamically generated and positioned using the following code, however when I want to use them as buttons by using onRollOver or onRelease they act like I'm not scoping them correctly. In other words the cursor does not change into a hand when over them. This is a setInterval issue as if I have them open just using attachMovie, the scoping works just fine.
The actual code is as follows:
function aboutUs () {
var mcAboutUs:MovieClip = this.attachMovie("mcAboutUs", "aboutUs_mc", 20, {_x:197, _y:520});
var x_elasticTween:Tween = new Tween (aboutUs_mc,"_xscale",Elastic.easeOut,0,100,1,true );
var y_elasticTween:Tween = new Tween (aboutUs_mc,"_yscale",Elastic.easeOut,0,100,1,true );
clearInterval(_global.intervalID1);
} function setIntervals() {
_global.intervalID1 = setInterval(this, "aboutUs", 1000);
There are more in here, each going to its own function to attachMovie and Tween them. This all works fine.
setIntervals();
this.aboutUs_mc.onRelease = function() {
OnRelease is suppose to activate another function that generates the "About Us" page but nothing happens as if the instance is not been scoped.
page_aboutUs();
}

it doesn't seem like you can use locally scoped vars within a static block?For example I was thinking I could do:
Code:
public static var standardAgeRange:ArrayCollection = new ArrayCollection();
//static block
{
[code]....
but apparently I have to first declare _n as a static var of my class (or as a static var within the block itself) in order to use it within the static block.needed to do...
private static var _n:int = 2;
then in the static block:
for (_n=2; _n<120; _n++)
In Java I'm able to use locally scoped variables within the static block. I know this isn't Java, just wondering if I'm missing something fundamental. (I couldn't find a lot of documentation online concerning static blocks in AS.)

I see this type of apparent magic in all sorts of AS3 code, but here is a reduced example:
[Code]...
As indicated in the code comment, the loader variable should fall out of scope after the URLLoaderExample constructor. However... it still seems to be kept alive (not garbage collected) somewhere since the onComplete listener/handler is able to receive it cleanly. Where is the magic/hidden/global reference to loader that keeps it alive so that it can complete it's load operation, and then be handed to the onComplete listener/callback? Can this reference be seen somewhere?
To help with context... as a similar example, I know that the loader instance will have the onComplete listener registered. I also know I need to be careful to use removeEventListener at all times (?) to avoid potential memory leaks resulting from stranded listeners. What concerns me is that I don't understand where the magic loader reference is and whether (or when) I need to clean that up.

I have 3 movieclips on the main stage.
btn1, 2, 3
I have this code in the maintime line, that when i click a button, the btn the stays static (like its on), when i click another btn, it switches on the next button and loads an external swf.
Each button's instance name is button1, 2, 3..and more buttons I add the stage I would increase the button number, so for 3 buttons on stage I have up (var buttonNum:Number = 3
code//
var buttonNum:Number = 1;
for (i=1; i<=buttonNum; i++) {
this["button"+i].onRollOver = function() {
[Code].....
This all works fine.
I have built a scroller with thumbnails as movieclips and would like to add this code to movieclips.
The thumbnails are indivdual moviclips and are inside a movieclip (productscroll), as the dragbar i am using targets the clip (productscroll) to scroll the thumbnails.
I basically need the same actions as the buttons. When I click a thumbnail I need to load an external swf.
