I'm new to AS3 and I was making a game of chess. Basically whenever you click a square with a chess piece, I assumed it would be like java, and you'd be able to create an "ActionListener" that would pass a reference to a square that was clicked.
My question is this: How can I access this square object that was clicked in my array?[code]...
I have this code:
var service:HTTPService = new HTTPService();
if (search.Location && search.Location.length > 0 && chkLocalSearch.selected) {
service.url = 'http://ajax.googleapis.com/ajax/services/search/local';
service.request.q = search.Keyword;
[Code]......
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?
In a game me and a friend is creating, the levels are stored in MCs.In the level MCs there are several other MCs that the player should be able to interact with.
This means the objects in the levels need a stage reference.I can place all the objects manually and pass the stage ref in the constructor of the object's class, but this is a pain when the levels are going to be pretty big.
Is it possible to make sure that flash always passes a stage ref to the object even though it's not placed there by code?
I need to call a component and pass an object. Now I am using event initialize to pass into the method of component but it seem to execute only once as follows. Is there anyway that I can make it call every time it loads.[code]
View 2 RepliesI have one movie clip that sits partially over top of another movie clip. The underlying movie clip has a ROLL_OVER effect on it. Is it possible for the mouse to somehow activate the ROLL_OVER only when the mouse cursor moves over a portion of the overlying movieclip when it's over top the underlying movie clip? In other words, the ROLL_OVER event should be triggered by the mouse cursor as through the overlying movie clip wasn't even there, when the mouse rolls over that area.

View 3 RepliesSo ive made the switch from AS2.0 to 3.0, and like many fellow casual flashers, I'm having a bit of a tough time
I understand that below, the first trace works because the mouse event comes from the clicked object, and that the second produces an error because the ENTER_FRAME event is attached to the stage, so e.target is the stage. i realise i can attach the listener to the obj, but i need it on the stage for what im doing
How can i reference the clicked object from run() ?
ActionScript Code:
obj.addEventListener( MouseEvent.MOUSE_DOWN, doMouseDown );
function doMouseDown(e:MouseEvent):void {
stage.addEventListener(Event.ENTER_FRAME, run);

I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
I have a page that I'm working on that works great except I keep getting an "Output" message stating: TypeError: Error #1009: Cannot access a property or method of a null object reference. at StillFrameFoto_fla::MainTimeline/portfolioOut() I'm pretty sure I just need to get rid of my button instance, but I don't know how. I have my buttons on frame 1 and I want them completely gone when it moves to frame 2. Here is the code for one of my buttons on the first frame:
[Code]....
I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.
code below:
Code:
import flash.net.navigateToURL;
import flash.net.URLRequest;

I'm having to pass data (originally read via an XML file loaded by the parent class) to a child class upon instantiation, and I can't decide which is the better method.I could parse the XML in the parent and throw the data into an Object and pass that object to the child class....or just pass the part it needs as an XMLList and let the child class do the parsing.Seems like a trivial decision, yes, but I'm not sure of longer-term implications.

I have this really simple actionscript function and for the life of me i cannot figure out the correct way to pass in the frame reference name![code]
View 4 RepliesHow can I pass parameters by reference? So it doesn't make a copy out of it, but modifies whatever I pass in? This:
function ChangeString(string:String)
{
string = "inside string";[code].....
outputs "outside string", since functions seem to take objects by value. get multiple variables out of functions? Returning a custom class?
i want to pass by reference so i can use this variable outside the function.
What im doing is creating a global variable such as var cont:int; and then in a eventListener like enter_frame (stage.addEventListener..) calling a function called "mover", this function modifies "cont" value and i just want to print this value modified. The issue is i cant pass the value by reference just by const :S. The function is void, but if i change it to return int, its useless because each time i call the function, the value i want to return its created each time with a new value, beacuse i need to declare it so.. I read i can use a var such as Object but i really dont get it (im used to c++ i have to say)
I have Mac OS widget with flash. If to click on flash the URL in a window of a browser should open. But it does not occur. I use code like this:

How do I pass values by reference inside a for each construct in AS3? Basically, I want something equivalent to the following code in PHP:
foreach ($array as &$v) {
$v = $v + 1;
}
This would allow me to change all elements of the collection $array through a single loop.
In AS2 I have several arrays constructed like this :
var myArray0:Array=new Array(value,value,value...)
var myArray1:Array=new Array(value,value,value...)
var myArray2:Array=new Array(value,value,value...)
var myArray4:Array=new Array(value,value,value...)
...
What I'm trying to do is use iteration to reference each array name to pass it into a function.
Like :
function doSomethingWithArray(arrayToPass){
...
}
//Later somewhere in For loop... :
_root["myButton"+i].onRelease=function(){
doSomethingWithArray(WHAT-THE-HELL-I-TYPE-HERE[i])
}
I have 2 arrays, let's just say aSubArray and aMainArray. I set the values for aSubArray then use aMainArray.push(aSubArray); When I go to change the values for aSubArray, in the case of a for loop, all references in aMainArray are changed. How can a pass the values of aSubArray to aMainArray rather than just a reference?

Hmm, I replicated this situation in a blank movie and it works as it should.
when to use this in a classes?is there any specific rule?is it wrong to use this when you want to just access the stage that way?or is it better to pass the reference to the stage in the class constructor?

I'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?

Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."
I am trying to pass custom event data from 1 class to another class...here is my codes..[code]
View 2 RepliesI have code in a flex component that I want to listen for an event, the source of the event is a custom class that's being run by another class that's being run by another class etc etc. I was under the impression that an event would pass throughout the whole application, so I was hoping if I dispatched the custom event in the class like so..
private function finishEvent():void {
var evt:EventDispatcher = new EventDispatcher;
var finished:Event = new Event("finishedInterpret");[code]...
the event gets fired basically when the executeBatch is finished, and the finishEvent is being called, but I'm the listener isn't getting anything. I tried setting it to db.addEventListener, but that had now effect.
