ActionScript 3.0 :: Class - Returning From Function?
Jun 28, 2010
I want to make class which will import picture into UILoader and then will show it. It looks like that:
ActionScript Code:
package mob.kopertownik
{
import fl.containers.UILoader;
[code]....
And into the *.fla file I have got something like this:
ActionScript Code:
var myPicture:Picture = new Picture();
myPicture.CreatePicture(fileRef.name);
When I have got everything ready and the all requirements are fulfilled there is nothing happening.

However, on a bright note its coming!!!! So far, everything is going well and I am now seeing the light with AS3I do have a question on returning a variable from a function that loads an external CSS. This particular function is located inside a LoadStyleSheet.as class along with another public function that sets text properties to fields when accessed. What I am looking for is accessing the stylesheet after its been loaded in another class. I know in AS2 I could use the Delegate method for something similar to this situation. Not sure what the next step is for AS3. Anyhow, function script is below.
ActionScript Code:
public function loadStyleSheetItem(loadStyleSheet_str:String):void {
var styleSheet_css = new StyleSheet;

In ActionScript 3, there are some classes that will represent a value rather than the class itself. It's hard to explain properly what I mean, so take this example:

I am refactoring some code. I have a PHP page that contains a MySQL query and stores the result in a PHP variable $my_result. This result is then echoed to a Flash SWF during embedding with SWFObject. I now want to call this PHP page that makes the query from a javascript function like so - one change I have made to the PHP is that instead of storing the result in a variable $my_result I am echoing the result. Javascript function to call the PHP page and make the database query

I have the following function defined in a class:
Code:
vidNetStream.onMetaData = function(myMeta){
_root.totalDuration = myMeta.duration;
//trace(_root.totalDuration + "!");
}
totalDuration is a private variable defined in my class.... how can I get that function to effectively save totalDuration?

I decided to turn this util into a class because I use it in almost all of my projects. Basically what it is is I import an XML file and it has all these HTML characters like & or and my function basically converts those strings of characters to its regular form ie: ['&' (&] or [' ' ( )]
so calling it in a FLA file would be something like this:
Code:
var entity:DeEntitizeHTML = new DeEntitizeHTML("bob & jim");
and here is my class file:
Code:
class com.dop.DeEntitizeHTML
{
function DeEntitizeHTML(my_str)
[Code]....
how to return that value back to the var entity in my FLA.

Is there any method that returns the Class name of an instance as a String? I would like to then pass that String as the parameter into the getDefinitionByName() method to create a new instance of that Class (whatever it is).basically, whatever I have stored in the variable 'currentPage' (which could be any number of classes I haev written), I want to create a new instance of (therefore re-instantiating it). this will then act as the method for a 'reload' button which is designed to reload whatever the current page/activity is.

I am trying to return a movieClip to a project variable, so it can be retrieved outside of a function. However it fails.
I tried to simply set up a variable so when the function returns, it has a storage variable.
Then i tried for a function to retrieve the variable content
However when i call the trace(mc) it fails as undefined [code]...

Say I have four sub-classes of 'Car'. One for each color. I want to have one function that can build and return a 'color-car' sub-class based on the passed value. This is a dumb example, I know, but it is precisely what I am trying to do only on a smaller scale.
public class Car
{
}
public class BlueCar extends Car
[code]....
Ok. You get it. This doesn't work for a reason unknown to me. I get 1118 errors which complain about conversion of BlueCar into Car, etc...

I need to load data from a database, so I created the following function and placed it in frame 2 on the main timeline.
Code:
getQuestionSet = function (category:String, subject:String, level:Number, count:Number):Array {
var questionSet:Array = new Array();
var writeV:LoadVars = new LoadVars();
[Code]...
Whenever I try to call the function, it fails to set the value of the questions array. It always appears empty(questions[0]-questions[10] have the value undefined). But, if I check the values from within the function after I have set them, it works, so I know that it is receiving the values. What am I doing wrong?
Code:
questions = getQuestionSet("Art and Music", "Art", 1, 10);
Here is an example of how I have would call the function.

I have a question regarding classes.[code]What i want is that clue() should return me the value of NetStatus which is generated in returnResult() when this function is invoked.Now in this case var "f" will become undefined because Clue() is not returning anything, so how can i find a way that value of NetStatusEvent.NET_STATUS (in this case) will be returned from Clue().Although i can use ENTER FRAME EVENT to check when it has generated a status but i'm sure that there must be a better way.

I built a class that parses JSON data, stores it in an array, and now I want to return that data so that it can be stores in an array in my root AS file. I'm eventually trying to pass the returned array to another class. My class looks like this:
package com.src
{
import flash.display.Sprite;
import flash.net.URLRequest;
[Code]....
I keep getting the following error however:
1061: Call to a possibly undefined method payload through a reference with static type com.src.DataGrab.
Does anyone have advice on what might be wrong with my class, or a more logical way to write the getResults() function so that I can get retrieve the array being generated by this class?

I can use toString() to return any string desired when using trace(instance), is it possible to return other types of objects?For example, I may have this class:
public class List
{
private var _content:Array = [];
public function add():void{}
public function remove():void{}
}
I normally need to make a getter that returns the _content, eg:
public function get content():Array{ return _content; }
So that I can do things like:
for each(var i:Object in myList.content)
Can I make myList in the above case actually return the value of content automatically? So that I can do like:
trace(myList); // item, item, item (similar output as tracing an array)
for each(var i:Object in myList)

I am using Flex's Alchemy library to generate SWC's out of C files. I have a byte array (unsigned char buffer[size]) in the c-layer that I'd like to return to the ActionScript layer as a ByteArray. Do I have to iterate through the array and explicitly call AS3_Set on each element or is there a way to just return the entire C array at once?

I need to get the value inside a handler..
ActionScript Code:
public function verifyUser(p:String):String{
var verify:String
var variables:URLVariables = new URLVariables();
var varSend:URLRequest = new URLRequest("verify.php");
varSend.method = URLRequestMethod.POST;
varSend.data = variables;
[Code] .....
It's always returning 'null'. because its not waiting for the completehandler to be completed and just passes the null value of verify..

ok so i've been stuck on this for a while...What i'm trying to do is create a function that updates a global variable (randomVar) that is itself a parameter in the function e.g
[Code]....
Basically, i thought randomVar and vari were the same so when vari was changed randomVar would too but that's not the case. So how do i make the parameter equal the new value(5). I want to repeat the function using different variables so putting randomVar = vari in the function is not possible.

I have 5 buttons that onRelease (= when clicked) calls the same function with each a different variable.
contentLoader(profile);
contentLoader(projects);
and so on.
the function is:
function contentLoader(sName:String) {
trace(sName);
}
Now the trace returns 'undefined'...I just do NOT see it anymore The idea behind is that I want to use a moviecliploader to load in the content corresponding with the clicked button (projects.swf, so it'll use myMCL.loadClip(sName + ".swf"); That trick always worked, but like I said, it keeps returning undefined. Did I make a mistake by strict data typing sName as a String?

I have a function that returns an object full of data pulled when an XML file gets parsed. But I also need to use an array object with additional data. That array also gets built in the same function. Is there a way to return both? I am trying to get both the "Obj" and "SlideTime[idx]" data to use as globals.[code]

I am working with code where the variable "k" is a counter. I stripped out the extraneous stuff from the code below - so essentially when the function onExamPlusClick is called, the counter "k" and the minutes of an activity in an array both increment (as well as other things not shown). I'd like to return "k" as well as "activity[0].minutes" to the main program. Since the function is a MouseEvent, I'm unable to change "void" to "number"... and not sure how to return (pass) those variables back to the ain program.

In C you can pass a reference to a data item as a parameter to a function. then within the function you can write to that address thus passing back a value to the caller. Can you do anything similar in AS3?
I know you can use the return statement but I want to return a status by that mechanism plus a value in a parameter.

I am developing in Flash Builder 4.5 using as3.
I have created a class to connect, write and read to a TCP Socket using 'import flash.net.Socket;'
Within this class is an event listener which reads the incomming data:
Code:
socket.addEventListener(ProgressEvent.SOCKET_DATA, readSocketData);
private function readSocketData(progressEvent:ProgressEvent):void {var response:String = socket.readUTFBytes(socket.bytesAvailable);
trace response;}
My problem is how to output this data back to my main application. Ultimately I want to process the data and output it in a text box.
