Ive been asked to research the relationships between classes but having trouble understanding it.
Within my code, the class A creates an instance of class B inside it, storing the instantiated B in a variable in class A so that class A can access data members (attributes) and methods from class B.
How could I create a link in B so that it can also access information about class A?
I have Flash project that is set up something like this:
myProject.fla
- document class = myMenu.as
- the document class imports a menu item from menuItem.as (import menuItem;)
I have a function in myMenu.as that sets the text formatting for all the text fields on the page. I want to be able to use this same function in menuItem.as so that all the formatting is consistent & you only have to change it in one place. How do I access this function from both myMenu.as & menuItem.as?
I am dynamically creating a number of objects (movieclips) which all have a number of attributes.[code]and so on. i.e sub attributes. I don't think this is possible? Only sprite and movieclips can have dynamic attributes so unless atrbY is a movieclip (which it isn't, it's a string) it isn't allowed?Each object can have suboptions with further attributes associated with the chosen suboption.Later in the program I will manipulate, read and interact with the objects and they have text display behaviours dependent on the suboption chosen. That part (should) be straightforward! heh. One the object has the attributes attached in a usable format, accessing them should be simple.This will be for a store. i.e t-shirt1 has size small, price 10, size medium, price 12, size large, price 14. t-shirt2 has size medium, price 35, size large, price 40 and so on.[code]
This format of the XML can be adjusted if it would make the parsing easier.I am currently reading the XML in, stepping through, grabbing the individual parameter such as category and then adding it as an attribute of the object and it works fine. i.e. I end up with obj.category = 'catname'. However, on suboptions I am having a problem.Should I put all the suboptions in a multidimensional array and use nested loops to apply them to the object?I would still have the problem of objX.suboptionarray[Y].suboptionprice which isn't allowed? In the above XML case Y would be 0,1 and 2 giving 3 suboptions to objX and each suboptions would hold attributes such as pvid associated with that suboption.I could go down the horrible route, obj1.suboption1subptionprice ; obj1.suboption1suboptionpname; obj1.suboption1suboptionvalue; obj1.suboption2suboptionprice; obj1.suboption2suboptionpname and so on and so on for each suboption which could be five options (small,medium,large,x-large, xx-large) and which would "work" but would be bad programming and involve splicing names to get say, the "third" suboptions' price and pvid e.t.c
Going down the route of mutidimensional arrays sounds good except that on say 50 objects I would have stacks of arrays which I'm guessing isn't great in terms of resources?.Just to add, the number of suboptions varies between object, every object has a minimum of one suboption (default option) but can have as many as needed (unlikely to be more than 5 but should be scalable). i.e some t-shirts only come in medium whereas some have many sizes.I have a fair amount of leeway on the format of the XML which I generate from the database so the formatting of that could change to make the parsing easier.

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 have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I am customizing Google Maps for Flash.I have an external .AS file for my document class and one .AS file that extends the look of the Google Maps popup window.I am importing the locations of many apartment buildings from an XML file. The XML is being read in the main .AS file.There are textfields I need to populate in the popup.AS file but I don't know how to get that XML information from the document class .AS file into the popup.AS file. I wouldn't think I need to run an XML loading function in the popup.AS file right? how I can get variables from one .AS file to another?
View 4 RepliesHow would I set it up so that I can share a single piece of art across multiple files? My goal is to arrange it so that I can edit the art in the original file and automatically update the art in all files linked to it when published?
For example, I'm working on a character animation where the character appears in many episodes and the episodes are split into many .fla files. If I needed to change the appearance of the character in all of the episodes which are spread across many .fla files, I would I have to do it manually?
Say I create a swf and in it, I have two dynamic text fields. I do all the usual stuff like give these text fields instance names. I call this swf1.Now say I load swf1 into another swf, say swf2. Can I set the values to be placed into the text fields in swf1 from within swf2?

flash video that incorporates buttons to share to sites like twitter or facebook? For example at the end of a video at youtube you are presented with a share button. At vimeo there are links on the right hand side of the video for like, share, embed, etc. Are these buttons (i.e. links) added during creation of the video or are they added by the site itself?
I am trying to build a small site that allows a user to upload videos and have a 'share to facebook' and 'share to twitter' button show up in the video when the video is done playing.
Can we do remote desktop sharing by using AS3?
View 2 RepliesI have an issue with an apparent bug in Flash Pro CS5.5. I have recently upgraded to CS5.5 Master Collection from my previous version of 4.0. The bug is when I create a fonts FLA file with fonts embedded in it that I want to use throughout an entire site. I correctly configure those fonts as export for runtime sharing.
In any other FLAs in which I wish to use the shared fonts, I either (a) drag the assets from one library to the other, or (b) add them to the new fla and configure them as import for runtime sharing (both of which achieve the same result).

View 4 RepliesI'm developing a web app based on videos that my client would like to upload using an online resource such as YouTube or Vimeo. Since YouTube has a 15 mn restriction length on the videos one can upload, my client has decided to use Vimeo instead, but Moogaloop(!) the Vimeo AS3 API is fairly restrictive and only offers a handful of methods to control the video.
What would be your best AS3 API for an online video sharing site? By best , I mean one that allows as much control as possible over the site's player features. I need to be able to listen to events , control the fullscreen capability , enable/disable some specific features such as a "embed" or "share" button.
I have two MovieClip symbols in my library and I want them to share the same class, but Flash doesn't allow me to assign the same class to any two different MC symbols, so instead I created two bogus classes which extend the class I wished to share initially.
So having two MC symbols defined by 2 different classes extending a different class allows me to share the same piece of code.
My Question: is there a better was to share a class between 2 or more different library symbols?

View 0 RepliesLets say I have two swfs A and B, and at runtime, swf A loads swf B, and I wish to share code between them, to minimize file size and download times.If swf B has some code (say. com.blah.HelloWorld), I tell the compiler to have swf B's source in swf A's classpath, but only do a compile-time link and not actually compile com.blah.HelloWorld into swfThis works, and I have tried it, using a the -includes and -externs compiler options.However, My problem is that I wish to do this the other way. i.e. swf A and B (and potentially swf C) all need com.blah.HelloWorld, but I want com.blah.HelloWorld to be compiled into just swf A, have it as an external reference in swf B ( and potentially C as well.)I tried doing this using the externs and includes, but I get ReferenceErrors when I do this.
View 1 RepliesIn my library I have a few symbols (with diffrent graphics) that I want to share the same class (the same methods I written in as3).
First I tried to set the same name on the class line when converting to symbol but Flash then tells me that the name have to be unique. So I tried diffrent ways of inherit the class in each symbols custom class, but I didn't get that to work either..

Since I can access the library assets from external class, I have a question :
1. Is it possible to use any of library assets of one movie into another? Let's say in my movie A, I have McA1 movieclip in the library. Is it possible to access/display/addChild McA1 in movie B?
2. If there's a case that Movie B is loaded into Movie A - does all the library from Movie B will be inherited into movie A - vice versa - so it makes them accessible?
3. If the answer of 1, and 2, is no and no, is there any work around to make any library asset accessible accross the board? Is this what so called runtime sharing? Do you have any resource that I can refer to?
I have two classes, classA and classB
classA is created on the maintimeline

one of the methods dispatches an event
dispatchEvent(new Event("createdIt")
How do I create an eventListener for this event in classB?
I'm working on a project that uses a lot of "widgets" that are displayed in the main application. Many of these standalone swfs where the same code is incorporated several times ( for instance TweenLite ). I want to optimize this by removing this added code from each widget to reduce load time. I'm working on Flex Builder, but this is an actionscript/flash project. I'm not sure how I should do this
View 2 RepliesI have four instances of the same class called Tile, that is bound to a movieclip with four frames. They're imbedded in a movieclip that I'm using to hold all of the visuals.In the main class of my .fla I declare a variable called menu1 that is bound to another movieclip with 2 buttons on it.
I'm trying to make three things happen here: on clicking the Tiles the menu will pop up over the tile that was clicked; that on clicking another tile when the menu is already up it will close that one before adding a new one; and lastly, that on clicking the second button in the menu, it will change the frame of the tile clicked and close the menu.The tile.as has an addeventlistener in it's construction method to add the function onTileClick to each Tile.
public class Tile extends MovieClip{
public function Tile():void{
addEventListener(MouseEvent.CLICK, onTileClick);[code]....
This works fine for one tile. I can click on it, the menu pops up, I can close and reopen the menu as many times as I want, and I can use the other button with no problems.Also, clicking around on different tiles moves the menu around without repeatedly adding it, so that seems to be working fine as well.The problem is this: If I click on a tile, close the menu, then click on another tile and close it, I get an error 1009.It still closes, that error just comes up. And it will come up for any more tiles I open and close it on.Then, after clicking on however many tiles, if I do click the advance button, it affects all of the tiles, and I get an ArgumentError: Error #2025 for each tile clicked on.I tried adding a variable that held the event.target value in the onAdvance function, and using that for the gotoAndStop, but the same thing happened. When I tried tracing the name of the variable, I noticed that it was tracing the names of each tile clicked with each subsequent trace.
Am I building this all wrong?I thought that making a class for my tile object, and adding eventlisteners to the class, and adding the functionality of the tiles inside of the class would be good practice for Object Oriented Programming, but it seems to be producing nothing but errors. When I defined these tiles inside the main timeline, with separate event listeners, I didn't have this problem
