I need to make a function that creates an object based on each set of data in an XML file. I am currently using bracket notation to do it, but don't know how to increment the next object's name dynamically. I wanted to do something like this:

Is there any AS3 library or code-snippet that can create altered versions of a Sound object on-the-fly (at runtime)? Either based on:

I'm building an application, where objects are attached on a canvas and the tree of that canvas is held on a tree component. Each time that i attach an object the tree adds a new child etc. I want to do this on the other way around.. I want to press a tree node and "communicate" with the specific object, so that i can change its color, delete it etc. I've tried some things but nothing happens!This is my code:
var working_space:XML = new XML();
working_space.addTreeNode("Canvas",0);
myTree.dataProvider = working_space;

I'm used to building web apps using proper architectures, but relatively new to the RIA space.One of the issues in rich client app is approaches to handling communication across components. (I've played around using the EventBroker concept.)In a recent Flex3/AS app I was looking at they took an approach that seemed to work pretty well, but I wonder about the drawbacks (or any other pros)...They took the concept of having a singleton object that would hold objects that could be used obviously from any components within the app by a simple call to...
var myAppModel:AppModel = AppModel.getInstance();
You thus could put any objects in there that you wanted access to from different components. It seemed to serve as the equivalent of a "Session" in the JEE space. I'm not so sure from an OO perspective it's the best thing to do, but it did seem to work pretty well.
I have been trying to fix my collision handling for hours now, but it seems like I am running in circles. To be blunt, my collision handling sucks. It is easy to break, and hardly works on complex objects(like water in my case, see the test at megaswf . com / serve / 1577272)
For collision detection I am using the collision detection kit, or CDK.My level is made up of different large MCs, such as a "wall" MC containing all of the smaller walls, such as water, a tree, or a wall. CDK allows me to hittest the single walls by hittesting the large one, and not each one individually, making it easier for myself.My code has a lot of repetition(8 directional movement), so I will put a "//..." to simplify.

I just discovered impure.com and was very impressed by what can be achieved in terms of visualizing data using their workspace. Although the platform is free to use, but not open source yet. This causes a few problems because the API section works with .com sites for eg. for ebay, so I cannot visualize ebay listings for regional sites such as ebay.in because the link to ebay.com is hardcoded.I searched around, but didn't find other projects that offer a similar way to work with site APIs and other data sources with the kind of user interface and detail that impure.com does in a realtime way within a browser window.This brings me to the questions:
-What technologies would be involved in creating a similar kind of project
-What are the open source tools that can help develop a fullscreen UI to render the workspace. Are there any alternatives to flash for this, and how do they compare
The goal would be to use standard python data structures, python scripts to do some processing on these data structures, scripts to gather data from csv, json and API sources such as google yahoo, wikipedia and flickr, and scripts to render graphs, tag clouds, network visualizations etc. Then bring them all together into a visual interface that supports drag drop and simple type checking.How would the python backend integrate with the UI.
I'm building a sidescrolling world where you can move around.The idea is that you should be able to move to any point in the world, as well as travelling really fast.I'm pregenerating a long list of data about objects to place, their positions etc.
Now. When moving to a point far away from current position I don't want to loop through the whole list of objects to find what objects should be seen and not, so I'm thinking I should divide the position list into sections, each covering an area equal to the visible area. That way I would only have to roll through the lists closets to the new position.This would however result in an array of thousands of elements each consisting of about 20 objects and I'm figuring that might not be very healthy.One solution would be to split everything up further so that in the end I would have a handable nr of arrays containing a handable nr of elements.
You're probably thinking I should generate positions on the fly, but since one place in the world can be revisited I need to store all positions.
I've run into some problems trying to handle large text files in AIR (300+ MB in size). I can open a filestream and read the file just fine and even store it into a string variable. the problem occurs when i try to manipulate this data. Im trying to get each line as an element in an array so i can manipulate this data.Here's what i've tried:1. read the file into a string variable and perform a split looking for the newline character ). this freezes the program2. i've tried reading the file in one byte at a time and putting each line into an array AS it is being read from the filestream. This not only takes long but eventually freezes.
3. i've tried splitting the final string variable which contains the entire text file into chunks to process it separately.4. i've even tried putting the file contents into a sqlite database, but this also freezes.At this point, im not sure what my options are. Is AIR even equipped to manipulate data at this level? I could use a point in the right direction

I've written an application that deals with multiple languages, English, French, etc, I'm using Zendamf to retrieve multi-language data from a database, however, I'm running into a problem using Zendamf, and it could kill this project fast:
There seems to be an issue passing special character values via Zendamf. While querying a database that returns data including French-text characters (ie: Québec), the result returned from Zendamf is not handling the special characters (ie: instead of Québec, we receive Qu�c).
I've checked the output of the data via Php: the issue is not with the database result - the characters are returned correctly from the database to the Php result-set - I am able to print these characters correctly before they are sent through Zendamf, either by rendering them in HTML or by writing them to a log file.
However, once I plug the SQL result into an object and pass it to Zendamf, the special characters get mangled. Using Charles Web Debugging Proxy, I can see that the result values are mangled before they are passed back to my AS3 application.
I'm loading external data from a txt file into a MovieClip. It contains data that is crucial to the presentation viewing. It is necessary to load, not right away but at some point (the sooner the better). When the txt is on the same server it works instantly, but I'm loading data from another server.
Two problems: the onLoad code is stuck if the file doesn't load (connection problem, server down?) and in offline mode what happens if the data is purged out of browsers cache (history problem)?
How can i handle these exceptions?
1. Some code that uses a "timer" to periodically try to load the data again if the connection is slow and the txt doesn't loads the first time?
2. When it doesn't load at all, and the onLoad fails, how can I simulate notOnLoad - exception for data download fail? And retry the dataLoad?
I've already made cross-server data loading possible using crossdomain.xml policy.
The site is still in development. This problem occurred when the server which contains the data.txt was down due to maintenance, and when one of the test-visitors was downloading so much in the background that his connection didn't had enough bandwidth to load data correctly (browser thought he had connection problems).

View 1 RepliesFor a client, I am working on a project where a live RTMP stream is published to an Adobe FMS 3.5.6 server from a java application, using Red5 0.9.1 RTMPClient code. This works fine, until the timestamp becomes higher than 0xFFFFFF after 4.6 hours, and the RTMP extended timestamp field starts being used. I have already found: when the extended timestamp was written after the header, the last 4 bytes of the data were being cut off. I have fixed this locally, and now the data being sent seems to me to be conformant to the spec. However, FMS still throws an error message in the core log and then kills the connection from the Red5 client. Here is the error message:

I've been using this method of file uploading for a bit, but it seems that Google Gears has poor support for the newer browsers that implement the HTML5 specs. I've heard the word deprecated floating around a few channels, so I'm looking for a replacement that can accomplish the following tasks, and support the new browsers. I can always fall back to gears / standard file POST's but these following items make my process much simpler:
Users MUST to be able to select multiple files for uploading in the dialog.I MUST be able to receive status updates on the transmission of a file. (progress bars)I would like to be able to use PUT requests instead of POST I would like to be able to easily attach these events to existing HTML elements using JavaScript. I.E. the File Selection should be triggered on a <button> click. I would like to be able to control response/request parameters easily using JavaScript.
An example of uploading code using gears:
// select some files:
var desktop = google.gears.factory.create('beta.desktop');
desktop.openFiles(selectFilesCallback);

Edit: apparently flash isn't capable of using PUT requests, so I have changed it to a "like" instead of a "must".
im currently writing a piece of code where i need to get all children that are specific class or extend one.
currently im using this
ActionScript Code:
public function getConnections():Vector.<NodeConnection>{
var res:Vector.<NodeConnection> = new Vector.<NodeConnection>();

The problem with this is that 1st, string comparison is slow, and im expecting that there will be hundreds, of instances on stage. and secondly, It is very probable that i will extend the classes that i use in the functions, so their toString() will produce different name. e.g if i have on stage instances of "Node, ExtendedNode1, ExtendedNode2 " since they are all nodes, id like to all of them be returned.
I have airplanes that are flying past the screen from a top down view. when the air planes crash, I scale them down to make it appear as if they are falling closer to the ground and farther away from the screen. I have turrets on these crafts as well. they are seperate objects from the air plan. I scale them down as well. The only problem is they dont reposition correctly. they stay in their x and y positions even though they are being scaled it looks as if they are being pulled away from the air plane. is it possible to reposition them correctly based on the size on the object they sit on (i.e. the air planes)

View 1 RepliesIve probably ran into some code like this before. just cant remember where. I have 2 display objects on my stage.

Im using Oracle, BlazeDS, Java and Flex. I have a list of objects displayed in a datagrid(Lets call them Main-objects. Each of these objects have a set of UserComment-objects associated with them(One-to-Many relation in the DB). These comments may come from two different "types" of users, distuingished with either a 1 or 0 in the UserComment-object's "userType" field. Each time the user selects a Main-object in the datagrid, the UserComment's related to this object is displayed in a separate datagrid below.Based on the introduction, i want to separate the UserComment's into two separate datagrids (one for each user-type), instead of the one i have now. So my question is: What is the best approach for performing this task? What is the best way of separating the UserComment's into two separate data grids based on the value of the "userType" field?

Any good tutorials on dynamically duplicating movie clips (and working with them, loading into them) based on information (the number of object tags..) in a xml document?
View 2 RepliesI've been trying to sort objects depths based on their Y position but have not been able to do it efficiently. I was able to successfully sort objects with a selection sort algorithm and a quick sort algorithm; however, both have only been partly successful. Selection sort gets about 8-10/30 FPS with 13 objects and gets about 14-18/30 FPS. This is not good enough as I figure I could have as many as a hundred objects to be sorted at once.
After digging around, I found that array.sort() is more efficient than a quick sort implemented in AS3 and that calling swapChildren() or swapChildrenAt() at every swap was bogging it down. So now I am copying the objects array and sorting it with sort() and then comparing the two and swapping displayObjects so as only to call the swapChildren() or swapChildrenAt() method once per element. It appears to be running, and at full speed, though it won't swap correctly. Here is my code:

I've used Authowrware previously and it was quite easy to create a large string of data (a comma separated list) and export that to a text file (and create the text file if it didn't already exist).

Each record may have a few hundred data points in a comma separated list.

Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.
