ActionScript 3.0 :: Access Main Timeline Variables?
Dec 30, 2009
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 a game which consists of 5 frames.frame 1 asks if you wnat to play and that clicks thru to frame 2. I have a meter which is a movieClip, and if the meter goes to the last frame, there is an onEnterFrame listener that I want to tell the main timeline to gotoAndStop at frame 5, here is the eventlistener code:
this.addEventListener(event.ENTER_FRAME, youLoseGame);
function youLoseGame(event:Event):void {
stage.root.gotoAndStop(5);
//stage.gotoAndStop(5);
}
I dont understand how to access the main timeline

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.

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 MC with a class attached to it, and I have other MCs within that MC. I need those MCs to be able to access variables within the main MC class. Here is a quick'n'dirty:
Code:
class Foo extends MovieClip{private var h:Number;
private var subMC:MovieClip;function Foo(_h:Number){h = _h;}
subMC.onEnterFrame = function(){trace(h);}}
How can I access variables in the Foo class from another MCs scope? I have tried using static var but aren't they constant regardless of instance?

as always, this seemed simple in AS2, but i am stumped with this simple command in AS3.
i have a main timeline [one scene] that has multiple movies, one after each other, in different frames. i need the buttons that are placed in a layer below the movies to access various movies in the scene. was really simple in AS2.
it appears that i can get my button to go to the frame, but the movie contained in the frame will not load and or play. [i have 2 frames dedicated to each movie, the second frame, in the actions layer has a stop command]. the following is the actionscript and the errors i am getting.
AS3:
food_btn.addEventListener(MouseEvent.CLICK, playfood);
function playfood(event:MouseEvent):void {
gotoAndPlay("food");
}
[Code].....

I have a class, and I'm trying access an object outside of that class. For example, in my class I have function: onNodeLoad(node:Object)with that function I can access the properties of node just fine, but outside the class I cannot.In the function that is inside the class, I can trace (node. title)I want to be able to do that trace on the main timeline.[code]So right now, in my main timeline, trace(con.node) comes up null.I've tried to declaring _node public, private, public static.

I have two frames in the timeline of my flash file. On frame 1 there is a movie clip. How can I access this movie clip with code located in frame 2?
It doesn't matter whether the mc is already placed on the stage or is added dynamically from the Library - I just need to access the alpha property. I can provide a more detailed description of my file if needed.

I have a class called Butterfly that extends MovieClip and exists as an asset in my Flash CS4 library.
The timeline of Butterfly consists of different wing flaps for different segments of its behavior. One of the animations is the wings opening up. Once the wings are open, dynamic text is shown on the wings of the butterfly.
Code:
//Butterfly.as
...
private var _textForWings:String = "Text For Wings";
I don't seem to have access to that variable from frame 159 inside of the clip.
What is the right process for accessing variables defined in the class by the frames inside?
Currently I'm using a getter for the _textForWings variable and using
Code:
//getter inside Butterfly.as
public function get textForWings():String
[Code]....
In this instance this works, but this things that i specify in the class are not avaiable to me within the timeline where i need them issue is really causing some headaches.

I have a button inside a movieclip. When the button is clicked I want it to make a movieclip in the main timeline go to a specific frame. what's the code I need to use to define that movieclip located on the main timeline? Right now I have my code written inside the movieclip where the button is located because I have multiple buttons on multiple frames, and I don't know the syntax to define a button in a specific frame inside a movieclip.
Here's my current coding...
Code:
Select allfunction bwbtn2(btn:SimpleButton,frame:Number) {
btn.addEventListener(MouseEvent.CLICK,function() {photobw_img.gotoAndStop(frame);});
}
bwbtn2(bw19_btn,19);

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 have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."

Working on an RPG type flash, and I have to be able to control a text-box from quite a few locations. The one that is causing me trouble is the inventory. I need to be able to access the textbox with an instance of "statusWindow" from within the inventory clip (instance name "inventory"), so when I mouse over an item within the movieclip it will change the status window on the stage.In this instance I want to mouse over inventory.invHealth from the main timeline to get the display.itemName and itemProps are strings containing information about the item.I tried the following but it gave me a "possibly undefined" error.
invHealth.addEventListener(MouseEvent.MOUSE_OVER, itemStats);
function itemStats(e:Event):void
{
root.statusWindow.text = itemName+"
"+itemProps;

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.
