I am new to AS3 and to writing classes, but have the following in my class to change the alpha of my button. How do I reference my button in btnOverAction, so I can set its alpha? Is there a way to reference the object the event was called on? I am calling the method to set up multiple buttons like this:[code]
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'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 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:

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;
import flash.display.*;[code]................
I rune the following code from TestClass:
ActionScript Code:
handler.loadFromFile("test5.txt");
dataset.generateComplete();[code]....
However, why does dataset.generateComplete(); get called before onFileLoaded(event:Event)?I can only assume that this is the case, as var pointList:Array = myHandler.getPointList(); returns Null, and when I run some tests with trace statements,I can see that onFileLoaded (event:Event) is seemingly called after generateComplete() Is the URLLoader process running in parallel to the rest of the application?
I am sending an event when an sql query returns no matches so that I can continue with the addition to the database.. It seems like actionscript is requiring that I attach the listener to something, but I don't really have any variables that seem like logical candidates at the point where I am in my code. I just want to listen for the isNewRecord event to be called so that I can then run the insert query; right now it's saying call to possibly undefined method for addEventListerner and for dispatchEvent.
public function addBG(BG:Number, datetime:String, batch:Boolean = false):void{
checkRecord('Gb', datetime, matchRecord);
addEventListener("isNewRecord", recordExists);
function recordExists(){
[Code] .....
Is there anyway of checking which mouse event called a function, without creating another function to handle each buttons event?
View 2 RepliesI'm trying to call an event I've created in another component. I've added trace() into my methods so I can see what's being called. Everything except for the event listener (myEvent) is being called.

So, I'm trying to load resources, add them to a dictionary, and have a drawing method search through that dictionary and draw based on certain predicates. I have a function that iterates through an Vector of Strings, calling on an instance of Loader to load them instantiated as a URLRequest.
private function loadImages(urls:Vector.<String>):void
{
var loader:Loader = new Loader();
[Code].....
So the issue is: Only the first images in my Vector are drawing. Upon further inspection, I found that the completeHandler was only being called once (I put a trace in the complete handler to check). However, the Loader is invoking load everytime the loop iterates. I tried instantiating separate loaders for each resource, just to see if it would work, but I had no luck with that. Do I need to make separate loaders and event handlers? Or am I just not using Loader correctly?
I need to fire and event when a function is called ...... And catch that event somewhere else.How can I do this?
View 4 RepliesI have a base class for buttons which handles button basics like mouse listeners etc.Now I'm trying to extend it to also have the possibility to store an event (yes event, not event type) that is supposed to be dispatched on click.So I have my CustomEvent (extending Event) that I pass into the base class and store it with type Event.Outside, in the event listener I have an event argument typed as CustomEvent.First time I click it works fine and event is CustomEvent traces true in the event handler.But the second time I click, event is CustomEvent traces false and I get the "type coercion failed" error (cannot convert Event to CustomEvent):
Code: TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::Event@29d3b7e1 to com.package.events.CustomEvent.
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at com.package.display.buttons::ButtonBase/onClick()
If I trace event is CustomEvent in the base class before the event is dispatched it always traces true.So it seems something happens to the event in the dispatcher functions, but what boggles me is that the base class always sees the event as CustomEvent while the event listener thinks it is CustomEvent first time only.
I'm trying to write code so that when the variable p_bw is greater than 0, an event is called. I've read that I need to use dispatchEvent but I can't seem to get it working .Here is my code....
package CIS.FLVPlayer[code]............
I have an AS 3.0 class that loads a JSON file in using a URLRequest.
package {
import flash.display.MovieClip;
import flash.display.Loader;
[Code]....
When the file is finished loading, the mapHandler event makes changes to the class properties, which in turn are accessed using the getMapWidth function. However, if the getMapwidth function gets called before it finishes loading, the program will fail.
How can I make the class wait to accept function calls until after the file is loaded?
i am trying to return an XML object, but having issues. The object is only created via an Event.complete function. I need to return the XML created from my loadXML function via my grabXMLfromFile function.

var fileUrl:String = attrPathToXML;
var myUrlRequest:URLRequest = new URLRequest(fileUrl);

I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

Is there an event that IU can assign a function that is called when an swf closes?
View 5 RepliesI'm using Delegates in a new project I'm working on to call an event handler in my class with the scope of the class.
I'm having an issue referencing which button is calling this handler. Since all of my buttons are created dynamicly, this is a big problem.
I'm used to using forms and components where I had no problem with this and could reference who was calling the event handler by using - event.target
This doesn't seem to be the case with movieclips though, is there another way to do this?
If I change the value of a variable that two different classes can see (in a custom global class, for instance), and then immediately dispatch an event that the other class is listening for, will tracing that variable in the listening class reflect the variable's new value? In other words, does code that executes in another class that's called from a dispatched event elsewhere still run procedurally, or is there some sort of asynchronous thing going on, where the class that dispatched continues on to the next line of code in its own class without regard for what may or may not happen in the other class?
View 2 RepliesI need to call FileReference.save() after a web service call has completed, but this method has a restriction: "In Flash Player, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception." (from the documentation here)
This restriction is a bit vague. Does it mean that I can only call the FileReference.save() method from within an event handler function that is registered as a listener for certain types of user events? If so then exactly which user events are valid? (Perhaps there's an event that will never be dispatched by user interaction with my application and I could register an event handler function for that event type and make the save() call from within that function?)
My difficulty is that I can't safely call the FileReference.save() method until my web service returns with the data that will be used as the argument of the FileReference.save() method call, so the event that triggers the FileReference.save() call is actually a ResultEvent rather than a user event, and I'm leery of dispatching a new (faux) user event type in order to be able to trigger the FileReference.save() call unless it's definitely a user event that would never be dispatched as a result of actual user interaction with my application.
In a nutshell what I'm doing now is this: I have a function that is registered as a handler for a button click. In this function I make my web service call to fetch data from the server. I also have a result handler function which gets invoked when the web service call completes, and it's in here that I want to call the FileReference.save() method since it's at this point that I know that the data is ready to be saved to a file. But the aforementioned restriction is blocking me from doing this -- I get an error:
Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press.
I've tried many things to get around this such as creating a second mouse click event handler function with the FileReference.save() call within and calling it after a timeout interval (to give the web service time to complete), but I keep running into the same error -- maybe that approach doesn't work since the second function isn't registered as an event listener for the event type used as its argument.
I am trying to have flash listen for a loadClip event when a button mc called portfoliob is released. When the loadClip event is triggered I'd like flash to then create another MC called container2 and load a .swf called pmenu. I understand the logic behind it but for the life of me I can not get it to work.

This was a simple test to use the transform matrix to rotate an object about its center point. But I noticed that the object was moving ever so slightly (up and to the left in this case). I added a bounding box so you could see the motion.

Is there method that gets called just before object destroyed? So I can override it.
Like
protected override function beforeDestuction():void
{
trace("This object is about to be destroyed!");
}
I want to do something simple like, "if an object called box is at x = 100, the timeline goes frame 2".

View 9 RepliesI was recently searching for a way to call the print function on a PDF I was displaying in adobe air. I solved this problem with a little help from this fellow, and by calling postMessage on my PDF like so:
//this is the HTML I use to view my PDF
<object id="PDFObj" data="test.pdf" type="application/pdf"/>
//this actionscript lives in my air app
var pdfObj:Object = htmlLoader.window.document.getElementById("PDFObj");
pdfObj.postMessage([message]);

I have an array name region it has a couple of properties. "code", "name", "value"
I want to store this array in an indexed object called regions.
I would then like to access the object by referring to its sub property name
regions[1].code
regions[1].name
regions[1].value
I can set an array region.code, region.name and region.value but I can not set the regions values
regions[1].code = "abc"
regions[1].name ="alphabet"
regions[1].value =26
note: region is singular and regions is plural(many)
Can someone outline the variable definition and construct so I can access this information. Happy to replace the index field with the code value.

Do not worry about the syntax of this code. Here is my concern - The loader object which is used to send the HTTP request and which has the onLoadComplete event registered to is not referenced from outside the loadSomeContent() function. Is there a possibility that the loader object will be garbage collected and loadCompleteHandler() will never be called?
I have a page with multiple flash objects which are written by a third party and thus can't be changed. They call a JS function but don't seem to pass any identifying parameters. Is there any way to determine inside the function which flash object called it?
