Media Server :: Can't Access Properties Of Date Object?

Jan 5, 2011

My FMS client is calling a function (simplified) which gets the offset time in milliseconds of an flv file.According to the docs for creationTime, it should return a Date object containing the time the file was created.I cannot access any properties of the date object in the server script.

Client.prototype.listFiles = function( folderName ) { 
var testFile = new File('/streams/folder/fileName.flv');

ActionScript 3.0 :: Access Object Properties In Class File?

May 27, 2011

I made a movie clip that is linked to a class named "Fugel". In the "Fugel" class I want to access the object's properties (x, y, rotation, alpha...) that I created in the main FLA file. I'm trying to center it in the constructor, but I don't know how to. The "this" keyword doesn't seem to work.

Here is the code for the "Fugel" class:

Code:
package {
import flash.display.MovieClip;
public class Fugel extends MovieClip {
public function Fugel() {

ActionScript :: Xml - Setting Object Properties From Other Object Properties?

Jun 25, 2010

i'm attempting to cast an object's property as an actual property of another object. here's my object variable: var propObj:Object = {prop:"width", width:50}; now i want to assign the property of a sprite using that object's properties. var sp:Sprite = new Sprite(); sp.(propObj.prop as Sprite.property) = propObj.width; now, i'm not even going to try that because i know the compiler will explode all up in my face. but you should be able to see what i'm trying to do. why i'm trying to do it is because i'm reading in an XML file with an undetermined list of usable properties for specific objects. so instead of writing something like a huge switch statement to evaluate whether the XML file has a value for that specific property, i'm trying to assign properties dynamically based on what's available in the XML file. if what i'm trying to do is possible, what's the best way to do it?

ActionScript 2.0 :: Trace The Properties Of An Object's Properties?

Jan 30, 2008

I forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?

Here is the code that I thought of, even though it doesn't work

var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties

[Code].....

This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project. If you want to see the unfinished project, go to [URL]

ActionScript 2.0 :: Retrieving Object Properties From Object Array?

Nov 11, 2007

I'm basically loading an XML file to assign instances of a movie clip a distinct value, which it uses to modify its height. So, I'm looping through the xml and instantiating my class Object each time (Rect) and then placing that Object into an array:

Code:
function loadXML(loaded){
if(loaded){
var boxArray:Array;
xmlNode = this.firstChild;

[code]....

the trace here always comes up undefined. "listPosition" in this bit is an Rect parameter, defined in the previous bit of code as "i", so I can keep track of the order of the stack.I've found one or two examples of putting objects into an array and getting them back out, but it doesn't seem to work with this, maybe because I'm using a class. I don't know.Could this be an area where I need to use the array access brackets, like around the movie clip the object is loaded into. I've tried everything I can think of -- referencing back to the movieclip, adding extra objectRef type parameters... nothing has worked yet.

ActionScript 3.0 :: Why Cant Access Properties

Feb 4, 2010

I have a movieclip in the library with the linkage name:BackgroundClip, so in the constructor I create it, add it to the display list and can even access and modify its properties, which I tested with the x position. Now what im having issues with is getting the stage resize listener to adjust the BackgroundClip instance, bg, to the stages width and height. In the clip is an image, so if someone has a better way of using classes to create full screen liquid gui im all ears![code]

AS3 :: Flash - Only Allow Access To Certain Properties On DisplayObject?

Jun 16, 2011

I have a getter within a class which is used to make my property skin:DisplayObject read-only. This class also has a property body:AvBody which is used to define the x y width height etc of the object, which in turn positions the skin.

What I want to do is disable access to the properties x and y on skin unless accessed from within the internal namespace (where AvBody is also located) Is this possible?

Note: I can't make skin any type other than DisplayObject (I can't even make skin a class that extends DisplayObject because it creates issues with library symbols).

ActionScript 2.0 :: Access To LoadClip Properties?

Jan 17, 2008

I need access to the properties of a file I load on the next line. Specifically, trying to pull the _height and _width off of it.

I think it's being bungled up because it's inside a function running two (nested) for statements. Let me post up the code for you geniuses[code]...

The width traces fine in the onLoadInit, but only AFTER the function that is creating and positioning the movieclips is finished running. They are nested in something of a complicated heirarchy so to save the widths in another array and then try to move them all later would be bonkers.

ActionScript 3.0 :: Access Loader Properties From Fla?

Mar 9, 2010

Let me just start by saying this forum is awesome, over the past 3 years I've found nearly all of the answers to my AS questions without posting once... That streak ends today.I'm building a site where the client is going to be able to upload various backgrounds which load depending on which tab they click on.

The class is BigBackground.as. It does the loading of the backgrounds, and then in the .fla I would like to manipulate these "BigBackgrounds" starting with the width. However, even though the width traces correctly from BigBackground.as, the width traces to 0 from the .fla file. I can access width from the class, but how can I access the width & height from the .fla?[code]...

Optimization :: Search Difference Between Array / List Of Object?

Mar 17, 2012

Premesis:I am using actionscript with two arraycollection containing object with value to be matched...Let's assume I have two list of elements A and B (no duplicate values) and I need to compare them and remove all the elements present in both, so at the end I should have

in A all the elements that are in A but not in B

in B all the elements that are in B but not in A

now I do something like that:

for (var i:int = 0 ; i < a.length ;)
{
var isFound:Boolean = false;[code].....

I cycle both the array and if I found a match I remove the items from both of the array (and don't increase the loop value so the for cycle progress in a correct way).I was wondering if (and i'm sure there is) there is a better (and less CPU consuming) way to do it...
