Actionscript :: Library Implementing A 'set' Datatype?
Jan 15, 2010
Has anyone implemented a Set class in ActionScript? Specifically, a Set which is similar to Python's set implementation (unordered, unique, O(1) membership, etc). I'd like to be able to iterate over it using for each, perform operations like union and intersection and get a list of all the contained items... Which would all be possible to implement using Dictionary and Proxy, but I'd rather not reimplement it if someone's already done the heavy lifting.
i'm working on converting an Action Sript class to C# and now i'm choosing a proper data types to replace ActionScript data Types ... and i wondered what is the best C# datatype to replace the Dictionary Datatype in Actionscript here's a sample code for example
public static const db:String = "http://dbpedia.org/resource/"; public static const rdf:String = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"; public static const skos:String = "http://www.w3.org/2004/02/skos/core#";
I am not sure what to datatype my currentSWF var. What is that? function onCompleteHandler(loadEvent:Event) { var currentSWF = loadEvent.currentTarget.content; swfHolderMC.addChild(currentSWF); }
basically what I am trying to do is dynamically add graphics using actionscript. So far it has worked but I ran into a problem. I am using addChild to add the pictures and the instance name.addChild(imageLoader). I need to convert the xml parsed data (xmlData.player[0].@position) to a instance name which I believe is data type MovieClip. So I am trying to convert my xml which is a string to a movieclip. Here are snippets of code:
var position:MovieClip = XmlData.player[0].@position; //Doesn't workgives Error #1034: Type Coercion failed: cannot convert XMLList@1f2d2e09 to flash.display.MovieClip. var position:String = XmlData.player[0].@position; //Does work

Through an XMLSocket, I get a basic datatype as a String value, such as "int", "String", "Array", etc... I would like to instantiate a new variable of the specified datatype. Something along the lines of the following psuedocode:
Code: function createVariable(type:String, value:*):void { var dataTypeRef:* = getDataTypeRef( type ); [code]......
The title of this post may not make much sense, let me explain. I have a function:
findSurface(origin:Point, vector:Point, attempts:Number):Point The function has an obscure use, but the idea is thus: given those three arguments, returns a point IF the 'line' (created by the origin and vector arguments) intersects the object the function is called on. [but that is another story...]
More importantly, if there is no point of intersection at all, what should the function return? Void? Null? Undefined? Object? Or can I use one of those return types instead of Point incase the function does not encounter an intersection?
I am trying to run an if statement based on the a variables datatype
var theArray:Array = ['element1','element2'}]; var theString:String = "I am string"; trace(gettype(theArray)); // In php gettype() is what I use to get the type. Is there a similar function in as3?
How exactly does the datatype checking of Vector work? The documentation states that an exception occurs at runtime if there was a wrong argument pushed to the Vector. However if I try this:
Code: private var numberVector:Vector.<Number> = new Vector.<Number>(); ... numberVector.push(thumbnailInstance)
And then I trace it, I get NaN (cos it is a thumbnail ). However, no exception is being thrown.
I have been following the samples code of Foundation ActionScript 3.0.
I have imported a jpeg into Flash CS3 IDE Library and Exported(Linkage) it to be used in action script by giving a class name 'Image'. And when I am trying to compile the file its showing error: 1136: Incorrect number of arguments. Expected 2. and 1067: Implicit coercion of a value of type Image to an unrelated type flash.display:Bitmap.
How to attach the jpeg to the stage as a Bitmap datatype using as3..
I'm trying to work out how to use states in my Flex app.I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1".But when I'm in design mode and click on State2, these elements are still visible?If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag.
I haven't used the implements keyword before, and I've been trying to use it to implement the IEventDispatcher class to see if this would allow me to use addEventListener() in a class that extends Object (this is my understanding of what it's for - correct me if I'm wrong).My class is like this:
implementing and editing XML within Actionscript worked out swell - no problems so far..but the some_xml.send() seems to become a true nightmare!
Soit, here's an example:
I made a little "keep-in-touch" maillinglist, where visitors can leave their adress, click the "send" button - and let the administrator view the list on a secure page. XML suits fine for this job, i think.
Code: on (press, keyPress "<Enter>") { mailInput_xml = new XML(); mailInput_xml.ignoreWhite = true;[code]....
I have a custom form that I want to implement and I am having a problem figuring out how to do so. I want to have it work like an inner popup where it blurs and unblurs the background imageHere's my setup:FLA file contains-UILoader for swf sectionUILoader for random background imageLets say I load a section called home.swf into the section loader. Within the home.swf I have a button for someone to call up the form.swf. Is it possible for the form to blur the random background image when loaded then unblur it when it's done? I also have no idea how to unload it.
I am trying to implement a preloader for loading an swf. I have an swf named 001.swf. I need to create a preloader for loading this swf. So should i create one more swf for loding the 001.swf.
I'm pretty new to Flash, and having a few problems with a website I've had to design for my college ICT course.I built the site entirely in Flash, which went perfectly, then went on to build a scrolling image gallery banner for use on a gallery page of the site (assuming that it would be an easy task to chop the banner into the website).When I've tried importing the file to the stage/library it leaves all the images behind (as they are in the library of the first file) as well as the actionscript required to call the images; leaving me with just a new, blank layer.I've also tried copying the actionscript code into the website document and transferring the images from the gallery library to the website library, however, the gallery is written so that the stage is used in its entirety to show only a certain amount of images, meaning that the proportions of the banner are all wrong on the website file.Is there any way to integrate the flash file for the gallery into a confined area of the stage in the website document, or am I going to have to alter my designs so that the gallery goes entirely across the page (put up and shut up style).
Attatched are download links to the two files in question, sorry if they're a little on the large side.
I cannot believe that implementing a simple class should be so hard. I am trying out the simple example outlined on the Adobe website: url...I copied the class code from here to file Greeter.as in subdirectory Learning. Then I created a dynamic Text field on the stage.
