I got this document class Main and a navbutton class. How can I connect a function from one AS3 document to another like this:
navbutton.as
removeObjects();
Main.as
function removeObjects(){
//code
}
I get this error: call to a possibly undefined method removeObjects.
I am trying to run a function of the main class, but even with casting it does not work. I get this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I'm attempting to write a performance testing function that can take any function, run it X times and spit out how long it took that function to run in AS3. I've got it working just fine if a function doesn't take any parameters but it comes up with an error otherwise.Here's the code:
public static function testFunction(targetFunction : Function, object : Object, ... parameters)
{
[code]........
I have object in which I have rectangle on one layer and following code on another layer:
[Code]...
And Object(this).play() or checking for current frame doesn't work, nor tracing a value define outside the function. How shall I reffer to the movieclip that events is called from?
My code is an external .as file. Google provides this code on their demo, which contains the this keyword:
[Code]...
Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.
Is there a way to reference a function via a variable? In other words, instead of saying something like:
var theVar = someString + 'function';
if (theVar == 'functionName') functionName ();
to access it directly:
(someString + 'function') ();
using some kind of bracket notation?
i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.
Code:
var Make:LoadVars = new LoadVars();
Make.onLoad = function() {
VARIABLE = Make.textVariable;

What's an example of calling a function through a reference (as opposed to directly)?
View 2 RepliesI thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:
ActionScript Code:
var bmpd:BitmapData;
var URLReq:URLRequest = new URLRequest("sample.jpg");

Got a list of MCs being populated from an XML file. Basically a list of two different types of information. Some are type A, some are type B.
Want to have a couple buttons that filter based on type (so if I push the button for type A (called "typeAbtn" below), only those MCs appear and type B MCs go to _alpha = 0 or something).
Can't seem to come up with a function to do it. I can't figure out how to reference all my MCs from outside the first function correctly.
terrible attempt:
Code:
function showMCs() {
for (var j = 0; j<stuff.length; j++) {
MC = timeline_mc["MC"+j];

I am using a delegate sub-class to perform helper functions for the main app.I have passed all references to it that it needs and it works well apart from the following problem:I also want it to remove an event listener from the main pp.eg:thisStage.removeEventListener(MouseEvent.MOUSE_UP,preOutsideBoundsDragRelease);The compiler tells me I need a reference to "preOutsideBoundsDragRelease" within the removeEventListener statement.eg: "access of undefined property preOutsideBoundsDragRelease
View 1 Repliesi 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)
Ok, I have a class like this:

I was just wondering if it was possible to get a reference to a function without knowing its name until runtime, in a similar way as getattr() can be used in python?
In python you can use it like this:

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])
}
Say I have a class B that extends class A.In class A, I have a variable that I've declared to be a function, which gets defined in the constructor. Now, in class B, is there any way to reference that function with the use of super.functionName()?

How would one get a reference of String global function (not class). According to language reference this function does exist (and I'm ready to believe it does), but, say and you have a:
Code:
function foo(bar:Function):void { ... }
How then would you pass that String to it?

This is because I believe it is referring the splashTimer1 function by "this".

Is it possible to reference a control in an application from a static function?
What I have is a Viewstack containing VBoxes stored in separate controls. Ex:
<mx:ViewStack id="content" width="100%" height="100%" resizeToContent="true">
<controls:Login/>
<controls:Dash/>

Once I get logged in on my login control, I would like to change the selected index of my ViewStack. From my outside controls, I cannot reference my ViewStack by name. I can reference a public static function from an outside control however I cannot refer to the ViewStack from within that function.
I am using foll0wing code to fetch data from XML file to flash.
Code:
function xmlLoad(fileName:String){
var pagedata:XML = new XML();
pagedata.ignoreWhite = true;

The problem I am encountering is that when I call function "createVar()" it looses the stage reference and "pagedata", my xml object.
I got a small problem with a null object reference. The problem is that the function "menuClicked()" not seem to work that good. It works fine if I'm not running it in the cases in the "urlChange()" function. But when I do so I get this error. The urls works fine btw. But I need to run that function to get the right content added regarding to the selected menuitem.

Hmm, I replicated this situation in a blank movie and it works as it should.
I'm wondering how I can create a reference to a function/variable by using strings. Sorry if I'm not explaining the problem well, but let me show you what I mean in an example:You can create a reference to a class using strings by using the getDefinitionByName as follows:var classRef:Class = getDefinitionByName("myClass") as Class;var myClass1:classRef = new classRef();Similarly, how do you refer to functions and variables? The reason why I want to know is because I'm trying to implement a function which takes in the event handler name as the parameter, and what the function essentially does is that it adds an event listener with the associated handler (based on the parameter) to an object, something like this:
public function addListener(handler:String):void {
mc.addEventListener(Event.ENTER_FRAME, "on" + handler);
}

So I am trying to access a variable that is defined within my parent code from a class which has been called from my parent code. I am using this:Code:TileCode(parent).game_quests.add_quest(0);to try to access the game_quests variable (which is defined within TileCode). However, for some reason it is not picking that up. It is working for other variables which I have called and ran in a similar fashion

I wonder what the most common reasons for memory leaks in AS3 are.First thing what I am not sure about is: is it better to have a variable reference inside a function or outside it. Will the variable be null-d automaticly inside a function or when do I have to null it and when not?I have massive problems with my game with memory leaks. I noticed I reference some of the clips of the timeline even inside my debugging clip to display propertys and this was causing collecting huge amount of memory.But even before I go into the game with bigger objects the System.memory is slowly growing and growing.I just have a socket connection and some interval loops and enter_frame events.

I've basically got an MC (menu_mc) that is on the first frame of the main timeline. I want menu_mc to call functions on the main timeline depending on its status. When the function is successfully called, I want to move menu_mc, however I get a null object reference despite the object menu_mc being visible on the stage.
here is the menu.as code
Code:
package {
import flash.display.MovieClip;
import com.greensock.*;
import com.greensock.easing.*;
[code]...
As you can see from the commented out lines, I've tried doing the same thing with eventDispatcher, but have been unable to listen to the event from the main timeline.It seems as if the function is being called before menu_mc is placed on the stage, despite the ADDED_TO_STAGE eventListener.
I'd like to invoke a function inside a mc from it's parent, but I want to have the reference to the clip be dynamic. When I path the mc directly and invoke the function it works, how would I make that same reference work dynamically.
Here's a sample of what I'm trying to do:
Code:
var myArr:Array = new Array();
myArr[0] = "galleryContainer_mc.eventGallery1_mc.imgContainer_mc";
trace(myArr[0]);
