ActionScript 3.0 :: Accessing Variables From A Parent Movie?
Nov 10, 2009
i am trying to make a basic preloader for an AS3 site. I followed the tutorial on this site (Preloading actionscript 3 the easy way) where its similar to AS 2 - create a Preloader movie and load the whole .swf into it.
only problem is i need some variables that i pass to the movie via QueryString parameters in the Object and embed tags. Is there any way to get this in my loaded movie?
i have tried
root.loaderInfo.parameters
and
stage.loaderInfo.parameters
and
parent.loaderInfo.parameters
none of them work. Can i create a variable in the prelaoder and just go "parent.thevariable" ? or does parent even work when something is loaded into a loader?

I'm trying to access the AchievementScreen's textfield from a medal object. Point being to have a mouseover event of the medal, change the content of the textfield shown. I tried a trace first: trace(this.parent.parent.parent.parent.textLineCon tainer); 1119: Access of possibly undefined property textLineContainer through a reference with static type flash.displayisplayObjectContainer. trace(this.parent.parent.parent.parent) shows me it is a AchievementScreen object. textLineContainer is the instance name of the MC nesting the textfield (I actually drew the achievement screen then exported it to actionscript.

What's the strategy for getting a child to access variables in a parent.I have a Main class.In that class I create instances of a Unit class and save those to an array.In the Unit class, I want to access the x and y coordinates of other instances of the Unit class.So I'd like to access that array I made in the Main class.I tried:this.parent.theArray[i].xbut that doesn't work. I tried using the get command, but I don't really know how to, so my efforts failed.

Wondering how to do this:
Parent swf has a class loaded, lets call it 'GlobalUtilities'. Parent swf loads in child swf. Child swf wants to use some of the 'GlobalUtilities' class that is in the parent.
How can I accomplish this? The problem I'm having right now is, when I export the child swf, I'll just error out since it can't find the reference (obviously, since it's not loaded into the parent yet).

What I am trying to do used to be very simple. I have a variable set in move A. Movie A embeds another move (Movie B) into a movie clip. Is there a simple way to call a varaible from movie a through movie b?If you need a little more detail here is what I am trying to accomplish. Movie a loads a list of information from a xml file and uses that data to set some variables within the content. (ie. based on the data it might caculate that the user listed in the xml file likes golf) Then it sets golf to true in Movie A. My problem is i need this variable throughout several of my movies and I dont want to do the calculation in ever single movie clip. I am sure I am making this much harder than it needs to be.

I've build several movies which all work fine, but ultimately they need to run inside a Main movie which acts as a holder for the various child movies which load into it.Everything is working fine but not when they're loaded into the main movie. The main problems seems to be that the main movie has common component which relate to all the loaded child movies.Consequently the main movie has several instances - but how do I refer back to them in the child movieclips?I can't get the child movie clips to compile if I remove the references but ultimately the child movie clips need to speak to instances and functions in the main movie.Also, I've got a global function to hold the global variables but this method seems frowned on. But I need the global variables all the time and in all the movie clips.

Lets say I have a movieclip on the stage.
On the stage on frame 1 I define a variable. Lets say its a string that reads "hello".
Now in my movieclip on stage I am trying to trace that string I defined on frame 1 on the stage. How can I make this happen?
I have tried a few things but I can't seem to get it working right.

This is probably a fairly easy answer, but I can't figure it out. I have a dynamically added child, and I have a dynamic text box on the parent. I'm thinking that it should be possible for me to add to the text box from the child timeline, but I don't know how to target the text box.

I've been using greensock classes in a parent movie, but am now looking to use the same classes from within some child movies, but it doesn't work (I presently have to import them into each child movie - what a waste).
Do I need to create the classes as a shared library object perhaps? If so, how would I go about it? as I've only ever done this for MCs or MP3s.

ActionScript Code:
function createMaskBox():void {
var maskBox:MovieClip = new MovieClip();
galleryContainer.addChild(maskBox);
}
creates maskBox under the function therefore not accessible form outside of this function from what i understand. Is there a way to create a var WITHIN a function which would exist as if defined outside of it, directly in code?

how to access a movie clip/s in a parent swf from a child swf. for example:Interface swf has buttons as mc's (home, about, services, portfolio e.t.c.) and loads in a swf when one of the buttons in the interface swf is pressed. When a button in Interface swf is pressed none of the other buttons can be pressed until the swf of the button that was pressed has loaded.
The reason for this is so that if the user tries to press the buttons quickly lets say the user pressed services button but changed thier mind right after pressing it and wanted to press lets say portfolio button they couldnt press the button until the services swf has loaded. Ive seen websites that dont do this and is makes it all mess up. Ive been able to do this in the past in AS2 but i cant figure it out in AS3.This is the code i would use in AS2:
Interface swf code is:
ActionScript Code:
_level5.btn_1.enabled = false;[code]...........

access a variable in a parent movie from a child you use:
Code:
(this.parent as MovieClip).my_variable
but what if you wanted to access a variable from a string?EX:
Code:
var varString:String = "myVar";
(this.parent as MovieClip).varString ?I have tried:
Code:
(this.parent as MovieClip).this[varString]
but it doesn't seem to work.

I have a "MainSWF", that loads and places other SWFs "LoadedSWF". The LoadedSWF has buttons that are supposed to make some layers in the MainSWF visible/invisble. These layers are in a placed navigation bar that is defined as a symbol, was placed on the Main Stage and given the instance name "FlashStageMainNavigation". I have a hard time figuring out how to address the layers in the MainSWF, because it seems I am missing something.
When I use a loop to trace all the child instances on the stage of the MainSWF with:
this.getChildAt(i).name
I get the following info:
instance1 this.name=0
FlashStageMainNavigation this.name=4
When I trace stage.getChildByName(this.name) in MainSWF I get "FSMain", which is the name of my main Class
My assumption was, that I could (from the LoadedSWF) address the Navigationbar in the MainSWF by using something like:
stage.FSMain.FlashStageMainNavigation.visible = false; //or
stage.getChildByName("FSMain").FlashStageMainNavig ation.visible = false; //or
stage.getChildByName("FlashStageMainNavigation").v isible = false;
neither of that worked.
To sum up/rephrase my question: How can I find out, which object instances are placed on the stage and how do I address them from the LoadedSWF?

I have a stage with instances of bauble_mcs on it that are attached by the document class of the main timeline (can someone tell me what the right term is here? I don't know what I call the main time line in AS3).I then have instances of snow_mc attached by the same class. Inside the snow_mc I want to test to see if it is hitting any bauble_mcs but I don't know how!
inside snow_mc I am trying:
PHP Code:
if(this.hitTestObject(this.parent.bauble_mc)){
}
to which flash says:
1119: Access of possibly undefined property bauble_mc through a reference with static type flash.displayisplayObjectContainer.
