When I create classes, often I want to remove methods of the parent class (such as addChild(), perhaps), and I just override the method and have it throw an error. Is there a way to remove it completely?
View 9 RepliesI got a "preloader" that creates an movieclip and loads an SWF. Now in the loaded SWF i want a close button to go back to the "preloader". The preloader isn't an actuall preloader but some sort of mainclip.Now i tried this:removeChild(MovieClip(e.currentTarget).parent.pare nt.parent)But i get error:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()at MethodInfo-6()
View 1 Repliesif I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.
In flash AS3 Do I need remove childs, if I remove the parent itseft? If I remove childs first, then remove the parent object afterall OR If I just remove parent object Will flash take same memory?
View 1 RepliesI have a child class that is loaded into the parent class when the swf begins, like so: var myvar = 'hello'; public function Parent() { this.child = new Child(); }; How can I retrieve the variable 'myvar' from within child?
View 1 RepliesImagine the following setup. The main swf loads a child swf.In AS2 i would simply use _parent or _root to call the desired function. How can that be done in AS3?Can this still be done? Can I call a function on the main swf from the loaded one? How about the other way around, this time, from main to loaded swf?
View 1 RepliesI have a parent class that instantiates a MenuClass and handles transitions between pages.[code]And here's the MenuClass which creates forward and backward buttons. Clicking each will tell the above ParentClass to transitionForward() or transitionBackward() respectively.[code]One one hand, I feel like the MenuClass is too tightly bound to its parent and is thus less reusable. On the other hand I feel like, in the interest of keeping everything self contained, it's not the ParentClass's responsibility to reach into the MenuClass instance and add event listeners there. This seems like there should be some kind of OOP rule-of-thumb to govern this kind of relationship.Is my MenuClass too tightly bound to its parent? And if so, do you have any suggestions that would loosen that coupling?
View 4 RepliesJust wondered if I remove a parent movieclip and then set it to null, will it remove all the child movieclips within it from the Display list and also from memory, or do I need to iterate through the parent movieclip removing all its children before removing the parent?
View 8 RepliesI'm working on a Flash MX application which involves a Parent movie and a Child movie.
I've loaded the Child movie into the Parent movie using LoadMovie. The instance name of the Child movie is Child1.
In the Child movie I have a user-defined function called getChildXML (we don't need to get into more details about the function).
The point here is that I want to call the getChildXML function from the Parent movie. I've tried something like Child1.getChildXML(); but with no luck.
I m new for OOP concept see this is my class, How this class will return values???
[Code]...
I'm new to AS3. I've got two classes.
damnMoles.as and startBtn.as
The damnMoles class uses a method called randomPlay();
ActionScript Code:
public function randomPlay():void {
this.gotoAndPlay("moleLabel"+randomNumber(1, 18));
}
Which basically allows the looped mole animation to start from various points in its timeline. I could probably use a different method to do this using an interval variable, but I originally coded this in AS2.0 and I want to update it, to see how this are different.
damnMoles class is attached to 6 mrMole# instances on the timeline.
Originally I used code on the main stage timeline to start the animation of the moles.
ActionScript Code:
startBtn.addEventListener(MouseEvent.CLICK, startClick);
function startClick(event:MouseEvent):void {
mrMole1.randomPlay();
}
This works fine, however, I would like to refrain from timeline code and use .as files. My startBtn class looks like this, but I get the error:
1120: Access of undefined property mrMole1.
ActionScript Code:
package com{
import flash.display.SimpleButton;
import flash.display.MovieClip;
import flash.display.Stage;
[Code] .....
So, how does this work? When I want to use a method from another class that has multiple instances on the stage?
I'm trying to call methods from a class to no avail. It just tells me that I have undefined methods.[code]

What if you have methods you want to use in your project, that really have no need of a class, or in other words, there is no need for an "object" associated with it. It's not going to have member variables, so why bother making it a class?
for example,
I want to create a randomNumber method, takes two numbers, low high, returns a random between or equal.
Originally in my code I had a very top level class i just called globalLibrary that extended movie clip, i put my randonNumber method there. Then every class in the project extended that. I got the method scoped properly, but to me it looks like a hack.
For example, the most basic functionality in flash like +, even = , trace, etc. Are these also methods defined in some class that we are extending? Or are they methods that have no object associated since that would seem to make just as much sense.
why can't I just create a file of methods, and import that file and have access to these methods?
SETUP: I have a MX2004 project where I'm attempting to pass a movie clip to a class, and have a method of the class act as the function for the onEnterFrame. PROBLEM: The class appears to lose reference to the movie clip when onEnterFrame() is called. TO DUPLICATE: Two files are needed, they are outlined below:

I need a way to reference to object (or the class methods inside). I have a button "Add box" and when it is pressed it creates a new instance of class "MyBox". The thing is everyone of these objects get the same name "box".Here's a hint of what it's like:
Code:
var arrBoxes:Array = new Array();
// var n:Number = 1;[code]...
Inside of the addBox function I can easily refer to the Object with just "box" (for example box.name = ..)but when in another function I cannot (and by then I might have created many "box"es).
If i instantiate class B (not a display class) in class A whats the best way to call some methods in class A from class B ?
View 3 RepliesIs there any way to add methods to the existing MovieClip class so that later I can use them everytime I instantiate a MovieClip? Something like this:
PHP Code:
package { import flash.display.MovieClip; public class myClass extends MovieClip { public function myMethod() { //do stuff } }}
Then, without instantiating myClass, I want to be able to call that method like this:
PHP Code:
var newMc:MovieClip = new MovieClip();newMc.myMethod();
i have a main movie. i use a loader to load a "example.swf" file. then i place that file inside a holder movieclip. in example.swf, i have an instance of a class i just wrote. this class has some particular methods. from my main movie, i want to call the methods of the instance of my class i have in example.swf. how can i do that??? i know it's a kind of casting, but none seems to work.
View 1 RepliesHere is the situation:I have created a movieClip named "tp_crack" on the timeline and created its class using linkage called "tp_crack".The tp_crack mc is like a small rectangle which breaks in 3 seconds when it is played.I have a seperate class in which I have used tp_crack to create many instances of tp_crack going by the names: cracked1","cracked2" etc.These instances are present in another movieClip (this time created within the class) called "crackContainer".Now I have added the following code to check for hitTest of those cracked1,2,3...... with a spaceship.The hitTest works but flash does not recognize the pieces as movieClips and does not play them as required, instead it gives me an error saying:1061: Call to a possibly undefined method play through a reference with static type flash.displayisplayObject.
for (var i:uint=0; i<crackedPieces; i++) {
if (crackContainer.getChildAt(i).hitTestPoint(Spacesh ip.x,Spaceship.y+(Spaceship.height/2),true)) {

I have this base class
package sevengames.miranda.front.res {
import flash.display.MovieClip;
import flash.text.TextField;
[Code].....
I then, in the Flash document, create a movie clip which has this class set as the "Base class" in the properties. However, if I then do this.updateText(); in the movie clip's frame script, it complains
TypeError: Error #1006: updateText is not a function.
at miranda_fla::MenuButton_3/frame1()
Why doesn't it work? I know the class is read and compiled, because I had an error there which was reported.
Any good 'real world' examples of when and why you might use the map and filter methods of the new Vector class in Actionscript?

I want to add a custom method so that any MC can use it like this - Code:text1.fadeIn(2) - which would fade text1 in over 2 seconds. The actual method isn't important, it's the way to add it as a custom method for ALL MCs that is confusing me.I can add it inside the document class (that extends MovieClip) like{/*fade in over tt seconds etc*/};But pretty much everywhere I look peoples are choking on their coffee shouting not to use that method. So is there a nice, clean way to do it without using prototype?BTW I want to add these methods in a class that is imported into the main document class at compile-time. So my main doc class has code specific to this SWF but the general external classes like Effects and Transitions are imported as needed.

View 1 RepliesI've got a custom class (using AS2) that mostly does things like set the score and level of a game, as well as sets the player's lives on the screen. I need to unload and attach MovieClips within the Lives control function, which require those methods from the MovieClip class. I don't think I need to extend this class from the MovieClip class, I think I need to import the class somehow. I don't know the path though..something like mx.MovieClip.
View 3 RepliesIn AS2 we can not add methods n properties to built-in classes in the way we do in AS1. Like we would -say- write the custom "isNatural" method on the "Math" class as follows : * The following code is valid in AS1 but not in AS2

As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1. Later I came up with senocular' s very nice tutorial on OOP in AS2. And now i know how we can do it in AS2 style in an efficient n organised way. But i have a problem with the following code. It should not work ! but it does... * Following code is valid for both in AS1 and AS2.
