ActionScript 3.0 :: Pass Arguments From An Event Listener?

Feb 22, 2010

In AS2, I often found it useful to pass arguments to a function on a button press like so:

btn.onRelease = function(){
doSomething("arg1", "arg2", "arg3");
}

I searched the interweb for DAYS trying to find how to accomplish this via an event listener in AS3, but everything I found suggested creating a custom Event. The problem with this, is you have to decide the arguments you wish to pass in advance, and I wanted to create them dynamically on the fly ( for example: passing a string that a user entered into a textfield to some function for processing ).

So last night I spent hours scouring forums - and UREKA! I finally found something that I was able to tweak to send a variable number of arguments of any data type. I've never posted on a forum, but it was such a breakthru that I had to share it with the world.

Here is the code:

btn1.addEventListener( MouseEvent.CLICK, function onClick(e:Event ) { displayArgs(e, new Array("Larry", "Curly", "Moe") ) } );
btn2.addEventListener( MouseEvent.CLICK, function onClick(e:Event ) {

[Code]....

Actionscript 3 :: Pass Arguments To Event Handlers By Reference?

Apr 9, 2010

I have this code:

if (search.Location && search.Location.length > 0 && chkLocalSearch.selected) {
service.url = 'http://ajax.googleapis.com/ajax/services/search/local';
service.request.q = search.Keyword;

I want to pass the search object to the result method (onServerResponse) but if I do it in a closure it gets passed by value. Is there anyway to do it by reference without searching through my array of search objects for the value returned in the result?

ActionScript 3.0 :: Pass Variable From Event Listener?

Feb 13, 2010

I headed some problem which can't solve. It's simple. I'm making slideshow, and wanna pictures to be dynamically loaded. List of images is stored in list.xml - a valid xml file. Now, here is piece of the code:

var imgno :Number ; //the var which tells the number of images listed in list.xml
var myXML:XML;
var myLoader:URLLoader = new URLLoader();

[Code]....

So, the triggered function processXML cannot change value of any variable which stands out of her. Is there a way to export (in this case) information about amount of images listed in list.xml to some of the variables that I can use later (for example imgno).

ActionScript 3.0 :: Pass Arguments Into Movie Clip?

Jul 29, 2009

I have been given the requirments to modify a website intro. Basically it has names fly in and out one at a time. Each name that flys in has some text effect on it. They had each name set up as it's own movie clip.

I want to make this more dynamic by putting the list of names into an XML file. Then after reading the XML file, pass each name one at a time into a movie clip. I thought I could set up several different movie clips for the different text effect and then randomly choose one.

I know how to read the XML file, but that's about it.

I need to know how to pass info into a movie clip. I need to know how to call random movie clips. And it would be nice to know how to make it loop through the names and have the effect appear on screen.

ActionScript 3.0 :: Pass Array Of Arguments To Constructor

Apr 17, 2010

I'm passing a DisplayObject to a command that will instantiate it. Something like this:

// ViewClass is passed into this method typed as a Class
var view : DisplayObject = new ViewClass() as DisplayObject;

Is there a way to pass arguments to ViewClass() without knowing it's type? I'm assuming the list of parameters passed to any object's constructor is an array, but I'm not certain how to proceed.

I know I can do something like this:

// Assume arguments, an Array of arguments, has also been passed in
var view : DisplayObject = new ViewClass(arguments[0], arguments[1], arguments[2], arguments[3], arguments[4]) as DisplayObject;

But clearly I'd like something more dynamic, like to be able to just pass the arguments Array directly. I suppose all of this, however, goes against any type safe checking

As3 :: Php - Using An Object To Pass Arguments In Any Order - Class Configuration

Mar 3, 2010

I want to pass through configuration arguments to a class. These are all the optional vars that go into configuring the class - and should be able to run in any order.

at the moment i just pass through the optional vars the regular way. Supposing the constuctor was like the following:

private var _reqVar:String;
private var _optVar1:String;
private var _optVar2:String;

[Code].....

assigning the argument to the var of the same key (i know in php to reference a variable name from a key you can use $$key = $value, is there an equivalent in as3?) display an error (using the 'throw' method) for variable names not supported by the class
