ActionScript 3.0 :: Accessing A MovieClip On The Stage From A Subclass?
Jul 11, 2010
In my flash document, I have a movieclip drawn on the flash stage (put there myself, not dynamically). I want to use this as a holder for an external .swf. I am using a sub-class to run the loading script. I pass the stage reference to it as the variable "theStage". It has no trouble loading things directly to the stage, but it can't find my movieclip for some reason. I have exported the movieclip for actionscript in the symbol properties panel and have given it an instance name.I've tried theStage.myMovieClip.addChild(mySwf); and suchlike, but always get this error message in output:ReferenceError: Error #1069: Property myMovieClip not found on flash.display.Stage and there is no default value.at MethodInfo-206()Some more information: It works from the main class without any trouble.
I am building a app that pulls data from xml. The different nodes in the xml needs to build different objects. My thinking was that I must import the xml only once. Then build seperate classes for each object type. These classes will extends the xml class and apply whatever it needs to do with specific nodes data. Problem is that it seems like the subclass is created before the xml loaded. I can trace the xml data from the xml superclass but not from the subclass.
Main Class
Actionscript Code: package MyClasses{ import flash.display.Sprite; import MyClasses.Dateline; public class Main extends Spriteprivate var dateLine; public function Main() dateLine==new(Dateline);}}
So, how would you create a class that can access a variable in the class where the subClass was created(superclass), I realise this might be unclear so in example
PHP Code: package {import flash.display.MovieClip;public class Main extends MovieClip {public va demoString:Strin = "TEST";public static var newClass:SubClass;public function
I'm using a preloader to load an external SWF then initiating it through its document class using this code:
Code: private function loaderCompleteListener(event : Event) : void { var loaderInfo : LoaderInfo = event.target as LoaderInfo ;
[Code]....
The problem i'm getting is that the Flash that is being loaded has a lot of classes exporting on the first frame, which now cannot be accessed, and therefore I get "The definition of base class cannot be found" errors.
How do I ger the items in the library that export to AS accessible by the parent loading SWF.

I've been working with/around and dodging a situation where I'm trying to access FLA library movieclip assets, but NOT from the document class. I capitalize this because this is my 4th forum posting. I know the answer to that one:
instanceName:ClassName = new ClassName();
The easiest solution for accessing library items from a SubClass looks to be this:
// at topimport TestLocalMC;// in constructorvar box:TestLocalMC = new TestLocalMC();addChild(box);
However, it doesn't show up. I tried a fake non-existent class. It gave me an error so I know it's referencing a Class in the library that I supplied. If I trace the object, it shows up. If I trace the X value, it says 0. So logically, it should be right in front of me..but it's not there! .Am I on the right track? Is this familiar at all to anybody? Is there something I'm missing?
if I could reference FLA library items with a bit of freedom from the document class. Having to go up the hierarchical class tree everytime to retrieve a movieclip is getting rather painful.
I am hoping someone can explain about subclasses accessing variables from the super class. I found that the subclass can only access variables which are set in the constructor of the super class. Is there any way around this?
I am writing a program in OOP and I have a custom subclass which I make a new instance of in the document class. When I do make a new instance of this custom class, I want this (the custom subclass is a movieclip) object to be positioned at the center of the stage. However, when I try
how to access library items in the main SWF directly from a SubClass by doing this:
package{ import SubClass; public class Main extends MovieClip{public var mySubClass:SubClass = new SubClass;this.addChild(mySubClass); }//class }//package
package{ import Box; public class SubClass extends MovieClip { public function SubClass():void{var train:Box = new Box;this.addChild(box);}//SubClass constructor function }//class }//package
But how do I access library items of a loaded SWF in the same fashion? Importing is different from loading and I'm not sure how or where to piece instances together at runtime.
I have a button, inside an mc1 which when clicked it plays [TweenLite.to(mc2, 2, {frame:1});] inside mc2 -which located back on the stage. Currently I get the error of "access of undefined property)".
I'm trying access a static variable located of a super class through an instance of one of it's subclasses and I'm receiving an access of undefined property error (example of which below). Creating another static variable in the subclass and assigning the value from the super class will allow me to dot operate to it.
I have created a movieclip (game_container_mc) in the main.as file and I want to add a child (enemy) to it from a different file (makeWave.as) how would I do this?
error When your accessing a method or property from a subclass. Here's what I have done so far but no luck in my script.
1. I tried waiting for my attached movieclip to be added to my stage using the setTimeout method but no luck.
var timedProcess:Number = setTimeout(initRevealDropDown, 1000); private function initRevealDropDown():void { clearTimeout(timedProcess); var myInterface:Interface = new Interface(); myInterface.revealDropDown(); }
2. I also tried extending my subclass to interface where my instance method is defined for revealing my dropdown menu, no luck on that one.
1.I have a MovieClip in the Library. There is a named and dynamic text box in the MovieClip. In Frame 1 of the .fla, I construct the MovieClip from the class StatusBoard and add it to the stage. There is one setStatus method in the class to set the text. This works fine.[code]
2.I have a bunch of buttons that I created from a class called LinkButton.as (they are MovieClips, not _btn buttons). FWIW, they are attached to other MovieClips, but they work fine. The trace output is fine. What I am trying to do is have the rollover change the text in the billboard.[code]
3. In lay terms, I used addChild to add a MovieClip with a dynamic TextField to the stagw and I want MovieClip buttons created from an .as class to be able to change the text on a rollover.What I can't seem to do is actually reference the billboard that I added using addChild from the .fla.The buttons work and trace the desired text, I can't seem to send that text to the billboard.
i've been all afternoon trying to figure out a solution to my problem, and I can't seem to find it, or cannot implement it. Let me lay it out for you: I have an actionscript file linked to a movieclip. (movieclip:skate class linked: generic_skate).I have it set up that way so I can create an array of skates easily (i'm using a for loop to create them), and each skate has its own attributes (name, description, price and the image that is supposed to go on the deck)In the stage, i have three text boxes, one for the price, other for the name, and another one for the description.In the generic_skate class, I'm handling all the mouse events (in this case mouseOver and mouseOut.
What i want to accomplish is: when the user hovers over a skate, the info shows up in the text fields and when he hovers out, the info goes away. My problem: Since I'm doing all the mouse interaction in the class file, my guess is that I have to access the stage to get to the text boxes that are placed there to change its info or somehow create a "middle" man to do all the handling.
I'm running into the situation where I can't instance a SubClass in the above SuperClass because the SubClass is extending from the SuperClass.
I get stack overflow. Fair enough, right?
Well, I want to add this SubClass to the display, and the only way I know how to do that is through addChild(). To addChild() I need to instance the SubClass.
I can't put any visual display instance or events in this subclass because it's currently null and extends is keeping me from doing so. It's great cuz I can share all the goods, but now I'm stuck dancing inside functions because I can't use events on the main "timeline" of the null SubClass.
I'm playing around with some classes from my Learning AS 3.0 book in an attempt to understand them. I have a main (document) class, and a class called NavigationBarXML.
Because the buttons for the nav bar are all set up in the subclass NavigationBarXML, I would like to position the nav bar relative to the stage (think btn1.x = stage.stagewidth - 50) from within this class. I understand that you cannot deal directly with the stage from a subclass and that you must add it to the display list before you can reference the stage from within this class.
How would I set up the main class so that I can reference the stage from my subclass so that on browser resize, my nav bar is positioned relative to the stage?
Is there a way to tell flash to instantiate a Stage subclass called "TheStage" instead of the default Stage class as root/parent of my document class? public class TheStage extends Stage{ //code }
Then when I do "DisplayObject.stage" I want it to return the instance of TheStage instead of the default Stage insteance. I want to do this so that I can override the addEventListener method of the Stage class. So if I call DisplayObject.stage.addEventListener I can execute my own code routine. Is that possible and how?
Can I access a static variable of a subClass' subClass? I don't want to instantiate it, just looking to get the variable because it has already been initialized by the subClass.example:
package { public class A extends MovieClip { private var classB:B = new B();
I have a Hero class that extends a Unit class that extends a SelectableObject class.[code]I have a movieclip in the library that links to the Hero. Inside the movieclip is another movieclip with the instance name "selector".In the Hero I can use selector.gotoAndStop (n) because the movieclip is linked to that class, but I can't do that for the SelectableObject because it's not linked to that.Is there a way to make selector.gotoAndStop (n) work for the SelectableObject? I can't even do var something:* = this.selector because the movieclip isn't linked to it.Or should I just remove the instance name for the selector in the movieclip so I can declare var selector:* = this.getChildAt (1) in the SelectableObject (the selector being the second child)?
I'm building a portfolio site for myself. When I load the Thumbnails class directly into the FLA, it works flawlessly. But when I load it into another class as an instance or through extends, nothing shows up. could post the code but there's a lot of it. There must be a very common explanation for this sort of no-show problem, right?this.addChild(thumb);for every dynamic instance loaded and it pulls a trace, but doesn't appear.

I'm working on a iPad game in Flash Pro CS5.5 and it was compiling correctly. Now I have marked a lot of MovieClip classes for Export for Actionscript so they use a custom MovieClip subclass as base class.
When publishing the movie I get a SWF without any actionscript in it (publishing takes also a lot less time then before). Now I have a suspicion this is because there seems to be a limit on the number of Export for Actionscript you can have?
The problem is that for iPad I can not split my .fla to create multiple swfs; since swfs that you load via the main document can not have any ActionScript in it (I tried already to put all the sounds in a seperate SWF with export for actionscript turned on, that didn't work).
In haxe I have a DropDownMenu class that extends MovieClip:
class DropDownMenu extends MovieClip { ...
TextFields are added to DropDownMenus (about 50 TextFields total):
// in a loop in DropDownMenu new method addChild(myTextField);
When a DropDownMenu is displayed the items further down are hidden as the menu goes off the bottom of the flash player. How can I make these DropDownMenus scroll?
I've considered doing something on the rollout mouse event. However I imagine MovieClip provides some mechanism for scrolling its contents.
I am plain stumped. I am working in F8/as2.0.I have a class that extends the MovieClip class. I have a blank_mc in the library that is linked to the class. Here is the constructor:
ActionScript Code: public function MyMC (target_mc:MovieClip){ var _mc:MovieClip = this; _mc = target_mc.attachMovie (.....); }
That works all fine and dandy. Where I am having issues is basically I have properties x, y that DON't overwrite the _mc's _x & _y props. Instead, the use getter & setters that take values and then calculate the needed number to set the actuall _mc._x, _y props. This doesn't seem to work at all and i don't know why. Here is the code:
[Code]
So I got this to work by NOT extending the MC. Instead I have a variable ref to a _mc prop in the class.However I am unable to set event functions to it even if I make some ref to the _mc prop. Is there a good way of approaching this by say a decorator pattern?
I have a movie clip "Obstacle" for a simple game. I have a class for it (Obstacle.as) that creates it, and moves it. In this Obstacle there is a text field - i use it for testing right now.
I want to make another Obstacle (HayBale) - with a subclass (HayBale.as). I have it mostly working. ACCEPT that text field.
It pitches this error:
1152: A conflict exists with inherited definition com.screenscape.game:Obstacle.myDisplay in namespace public.
