ActionScript 3.0 :: Inherit From Classes Defined In An RSL?
Jun 24, 2010
I have Class A defined in an RSL (technically, it's an art asset that I made in the Flash IDE and exported for actionscript. The entire .FLA was then exported as a SWC/SWF).
I my main project I have Class B, which inherits from Class A. The project compiles fine, with no errors.
However, when when the project runs and I try to create an instance of Class B, I get a verify error. Creating an instance of Class A works just fine, however[code]...

how I would go about creating a new instance of a class that inherits from the MovieClip class. Rather, I know how to adjust linkage properties inside the library, and can create new instances that way.... but my main problem is that a good number of times I find I want to create a new instance using the Constructor function, which is chock full of parameters that I use inside the class. I currently have a class called MenuButton, and if I use Linkage properties, I can make it all work just fine... But I also have a class called Menu, which arranges those MenuButtons... by creating them using MenuButton's Constructor. According to my code, these instances are created... but they are not visible and do not show up in the debugger.

I have a class which extends the Proxy class, and has a statically defined member variable called num:
public dynamic class TestProxy extends Proxy
{
private var num:Number = 100;
[Code]....
I want getProperty() to be called when I attempt access num. It works for any field which does not already exist, but not for fields that are predefined.

I have 3 .as files at the moment as follows: Launchers.as
Code:
package
{
public class Launchers[code]...........
Now what I'm trying to achieve is BounceGrenade and RocketGrenade classes to inherit the "maxAngle" property from their superclass "Launchers" so I could use code like:
Code:
trace(BounceGrenade.maxAngle)

I just started using flashdevelop and I have some problems with importing all classes.
1. I used export all classes to SWC file and I added it to the library in FD. How can I import instances placed on the stage without creating AS linkages? I don't want to export these instances for AS, because some of them are textfields. By making linkages I'm forced to transform them to Sprite or MovieClip (am I right?) and my methods connected to these object don't work anymore.
2. When I export my project in FD, I get error 1065: variable Main is not defined. Main is my document class. I made this class my entry in FD.

I am using flex builder 3.2, Action Script 3 and develop for Flash Player 10 and am quite new to it. when I call a method of a self defined class, I get the 1061 error (not defined). But the class and the method exist and are public, so what the hell am I doing wrong? Flash Builder is even offering me this method in the auto-completion, so at least the builder knows it... I have already tried cleaning the project (as this is the common source of strange errors when working with java/eclipse),
edit: solved... The problem was that a package had the same name as the variable I used for the class. Very strange error message, thumbs down for this .

I have the following panel component called AdvancedPanel with controlBarContent:
<!-- AdvancedPanel.mxml -->
<s:Panel>
<s:states>
[Code]....
Using the CustomAdvancedPanel inside an application component shows an empty panel with the "Go to edit" button. But when I click it, the "Extra edit button" becomes visible, but the "Show in edit" button inside the controlBar doesn't.
When the CustomAdvancedPanel is empty, without redeclared states and "Extra edit button" the panel works just fine.
I think it is because the State object declared in AdvancedPanel isn't the same as CustomAdvancedPanel, so the state is different, even if they have the same name. However. I can't use the states of AdvancedPanel inside CustomAdvancedPanel without (re)declare them in mxml.
Is there any way to achieve this kind of state-reuse? Or is there a better way to obtain the same result?

I have a Flash application with one MyApp.fla file and one MyApp.as file as the document class. The problem is that I need to implement my own slider with programmatically drawn notches controlled by custom properties. I want to inherit from Slider class and do all what I've mentioned above.

I am trying to build a class that inherits from the MovieClip class.Basically I am having issues in the constructor. Since MC's are unique in that they can only be created via createEmptyMovieClip or attachMovieClip, I am at a loss as to how you instantiate the inheriting class in the .fla? I figured if I just left the constructor out of the new class and do the following it would work but is doesn't:[code]How do I inherit from the MovieClip class and still instatiate the class using the above type actionScript?I have seen alot of information about inheritance and AS1.0 (which I have little understanding of). I am trying to stick to OOP practices and AS2.0. I searched for things like super & constructor to no avail.

I'm creating a Flex 4 application which contains different modules in it. The main application contains a style sheet and the modules inherit the styles defined in this file.Its working fine when the swf's are generated using Flash Builder. But when I'm generating it using Ant script, the modules does not inherit the styles and everything looks weird.I added isolate-styles="false" as an additional parameter to mxmlc, but still its not working.

I am new to Flex programming. I want to implement a custom toolstrip for an app. This tool strip will include a menu bar (or a customized equivalent) to display the common menu items such as File, Edit, etc as well as a search box. It should be flexible enough to include other menu items such as bookmarks, etc in the future. I have been thinking about mx:Group, s:BorderContainer, mx:HBox, but haven't been able to choose between them. And none of them seem espcially suited to my task as they merely specify layout of other objects. Is there any component which has direct support for such functionality. I have also thought about using mx:MenuBar but I don't know if it will be flexible enough to add non-menu items like search box.

I've got a bunch of mc's which I've put in an array. With these mc's you can do a lot of different things, like dragdrop and rotation. I also got a button which on mouse down, changes the image of the mc. It only changes the image.. not the size. So far so good...But when I've clicked the button and the mc's all change their image... They are not able to dragdrop / rotation anymore. I do not understand why this is happening... because by clicking that button... it doesn't change the names of the mc's.....here is the code:
ActionScript Code:
library = new mc_library();
library.x = 100;[code]....

Is there a way for the child of a movieclip object to not inherit the paren'ts properties? Because I scaled down the parent movieclip height and width and I'm loading external images into the parent movieclip and images are also scaled as well so I'm wondering if there is a way for it not to inherit the properties but remain inside the parent?

Ok every time I think I understand the DisplayObject model i find something else that seems like it should work but fails. Am I correct that if I create a sprite then create another sprite and add it as a child the original parent sprite will show a height of 0... In my case i have three classes that all extend Sprite and each one is creating the next with the "youngest child" being a class that adds an image to its "stage". I can see the image height fine but its holder does not nor does its holders parent... im having a real moment here as I debate if im just stupid and missing the obvious way to do this or if I really have to add a bunch of getters and setters to see the height that includes children.Maybe I am thinking of this too much like a CSS block element but it just seems like it should work this way...for example
parent "holder" <- child "slide" <- child "image"
holder.height == 0
slide.height == 0

I have been approached to design a configurator for a new television product. The Application will let users specify the colours of certain parts of the product and also attach addons, which then updates a cost total.
In the main interface i have a looping animation of the product slowly rotating around 360 degrees that i rendered in 3ds max. When a user clicks a button on the interface i need to load an external movieclip on top of the main animation so it looks as though a certain part has changed colour, this i have acheived. The problem is that when i load the external clip over the original, the loaded clip starts playing from frame 1 and i need it to inherit the playhead position of the main animation so the two layered pieces look as though they are rotating as one. I'm sure this must be possible, unless i need to approach the problem in a different way?

Is there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)

The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.

I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?

I'm loading an image into a blank_mc within a movieclip called 'background_mc' using the MovieClipLoader object; when the onLoadInit for the MovieClipLoader object is fired, i then attempt to clone my 'backgound_mc' object and the loaded image it contains so i can do something with it (i,e a funky masky/blur thing, not important right now)I'm successfully loading my image into the blank clip within background_mc, the onLoadInit behaviour fires and duplicates background_mc once the image has been loaded, but in a disappointing turn of events, my clone of background_mc no longer has an image attached, and has instead reverted back to it's original form, just as ti was before it had the jpeg image loaded in.

I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
