How do I fix this? With this code in my class:
function moveDelay():Void {
myInterval = setInterval(this.movePoints, delay);
}
I lose scope when it calls the function. "this" becomes undefined.
Why I am losing scope on an array that i define as a private member in a class? I am able to access it from a couple of different functions but in one place inparticular it keeps coming up "undefined". What causes scope to be lost in a function for an array that is defined as a private class member?

I'm trying to make a Class for a slideshow. I have a problem using the setInterval and clearInterval methods.See my code below. In the showPic function I have a conditional clearing the interval (repeating the showPic function). At least, it should do so, but it's not working. The interval continues. I'm using "this" so that's not the problem. Maybe it has to do with the scope of the variable to which I assigned the interval?

I was wondering why my current code for calling a setInterval on a function doesn't work inside my class.I have this code inside one function, calling a second function.
intID = setInterval(selfReferential, dupe, 30, 0x000000);
The selfReferential keyword refers to the current class,but was defined previously (selfReferential = this; ).I get no errors, but the dupe() function is never called.and I had the selfReferential variable replaced with the this keyword at one point as well.
I add this actionscript code on the first frame. Variables are loaded but. The question is below the code.

Normally when creating small apps, i create a small object something like this.
Code:
//Example
var theApp:Function = function(){
[code].....
Take a look at this code:
Code:
import mx.utils.Delegate;
class Test
{
[code]....
Well... Doesnt work at all... In the class, there isnt a instance of i, so, how may i access this property inside a class function? But i still have an way to access the class.
I could do this way:
Code:
class Test
{
function Test(mc:MovieClip)
{
[code]....
But this way, doesn't sounds good
I have this extremely odd problem. OK to start off I have an MC in my library with the linkage identifier "Interface" and the AS2 class "Player" (both without "" of course). Now, my player class looks like this.

I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
View 4 RepliesWhat is the scope of a class created in Flash? If you create a class on the main timeline, can you use it anywhere in your project? If you use your class in a a movieclip, can you use that class outside of the movie clip?
View 3 RepliesI recently completed a tic-tac-toe game in AS3, using some simple function-based code I had written in C many years ago.Now I'm on a quest to do it the "right way" using OOP techniques and best practices.Everything is now divided into neat little packages, it looks pretty, and the last part of my journey is to get all the little buggers to communicate with each other.I want to move the code which holds the game state from my main to it's own class in com.okaygraphics.model.GameState.The problem is nearly every other package gets and sets these game state properties.I'm trying to figure out the simplest way to encapsulate this stuff, while still allowing my other classes to access it.
1) Do I need a constructor? I mean, my program will never have more than one GameState. If I should call my getters/setters as instance methods, how do I get each other class to reference the SAME instance from their respective packages?
2) Do I even need getters and setters? Perhaps the class could just have 3 public properties? If so, how would I acheive the proper scope with regard to my other classes?
3) Should I assign everything to the class itself using the static keyword? If so, how would I implement and use those static methods?
4) Is this a mistake? Did I totally just program myself into a corner?

Specifies the value of thisObject to be used within any function that ActionScript calls. This method also specifies the parameters to be passed to any called function. Because apply() is a method of the Function class, it is also a method of every Function object in ActionScript. i don't get how "thisObject" is accessible from within the function invoked with it's apply method i'm trying to pass the scope of one class to the function of another so that the keyword "this" in the target function refers to the passed scope or am i misunderstanding the apply() method? it appears to behave differently between as2.0 and as3.0 as well, try this example code from the adobe docs

PHP Code:
import classes.LevelObj;
var newLevel:LevelObj = new LevelObj();
var levelListener:Object = new Object();
levelListener.onLoaded = function(oEvent:Object) {
[Code] .....
Now this runs great but in the loadLevel function of LevelObj.as, when I receive the event from the GBXML class that it has finished loading I want to call another function within the same class (LevelObj) to continue with further processing the XML data. What I make of it, is that I am still within the scope of the myListener object. Should I use a Delegate function here to get to the function within the LevelObj scope?And how about properties from the LevelObj scope? When doing a simple trace of some testVar I get undefined. Logical ofcourse because it is not within the same scope. But I am stuck here.
This is the part that should contain the call to the function..
PHP Code:
myListener.onLoaded = function(oEvent:Object):Void {
trace("LevelObj.XObj > "+oEvent.success);
if (oEvent.success) {
trace(testVar); //CALL FUNCTION HERE IN SCOPE OF LevelObj
} else {
How is it possible to access another movieclip inside a movieclip, if you have the movieclip linked to a class in the properties. ?
[Code]....
my workaround is to send the attached movieclip into the constructor of the class, then use it from there, this will somehow make it work. But then I'm losing the point in directconnect the baseclip to the class in the properties.. example: attaching mctest.fla (cs4 file) and baseclip.as
public function addNewMc():void{
var newMC:MovieClip= new MovieClip();
this.addChild(newMC);
}
public function removeOldMc(newMC):void{
this.removeChild(newMC);
}
How can I create a new MovieClip within a method, which can be used throughout the class, without defining it at the top of the class? And for extra points, without using return. I can get it to work, if the first function addNewMc returns the value newMC, and passing that to any other methods.
I'm not an experienced Actionscript user so I'm not sure what the normal way to associate a custom class with a movieclip that has been designed in the Flash IDE is. I made a class called Window to control a movieclip called TestWindow. There are some buttons in the movieclip whose
functionality I would like to assign the instance of class Window. How is this supposed to be done? Here's a representation of what I mean. I hope it is sort of clear. My actual problem is that the local variables are outside the scope of the onPress function but I also think there must be some other way of associating classes with movieclips that have been designed in the IDE.
My question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?
I have an object and would like to call a function from it, which the way I am trying to do it, does not seem to work. Here is what I have:
Code:
private function setTimer():Void

function onLoad(){
trace("Calling SetInterval");
setInterval(this,"resizeImage",1000);
[code].....
public function showImageAt(num:Number):Void
{
var interval:Number = setInterval(
function():Void {
[Code]......
so the test function never gets called...
I have a custom class called SpeedCheck, in this class I have a function called Activate(), I am trying to call this function using setInterval from another class but I am not sure how to format it.
This is how I would normally call the function:
ActionScript Code:
SpeedCheck.Activate()
I tried this:
ActionScript Code:
setInterval(SpeedCheck ,"Activate",100);
but it doesn't work, what am I doing wrong?
