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 add this actionscript code on the first frame. Variables are loaded but. The question is below the code.
[Code]...
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.
I seem to be having difficulty in using the contents of a variable whan i receive the data from the database the script places the contents in a variable called myText1This I need to access outside the function.This is part of the script below.
mypath = "http://192.168.0.100/fedpest/pestReports/"
mypath1 =mypath + "exterior.php";
var sendData = new LoadVars();

I'v attached a listener to a movieclip on stage but I can access any "global" varaiables which are out side the listeners function.I lose the scope or something what can i do about it? here is some code.
PHP Code
player.controlbar.muteButton.addEventListener(MouseEvent.CLICK,mute0,false,0,true);
public function mute0(e:MouseEvent):void {

I have 2 methods in a actionscript class.[code]I get duplicate variable warning. Is the local variable scope not limited to the method. Can't I declare same name variable in multiple methods?

I've been having trouble with scope in subclasses, where variables that I would like to be local to each instance of a class are instead global. For example:
Code:
class Prototype extends MovieClip {
//Various functions all clips have access to
}
class Ship extends Prototype {
[code]....
I've found that if I instantiate more than one ship, the hitboxes array is populated with clips from every instance of the class, instead of staying local to each instance as I'd like. Is this because I'm attaching them with a constructor?
My code:
Code:
onClipEvent (construct)

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'm working on a sliding gallery like Hulu. Setting it up and the sliding slides in and out is working fine. However, I need to add and then remove a button to each slide as it comes in and goes out. (I initially tried including the button on each slide, a mc, but this proved problematic for the event listeners). So when the file loads up, I add a mc to the first slide of the group like so (features[] is an array of movie clips - my slides):
Code:
var goBtn:MovieClip = new FeatureButton();
features[0].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
So I add the button/mc to the first slide - works just fine.
So there are two handlers, next and previous. So I started with the next handler. The first thing I have to do is kill the button on the panel that is sliding out, so I do that like so:
Code:
features[featureCount].removeChild(goBtn);
goBtn = null;
(featureCount is a counter keeping track of the slides). This works fine. I click the next button, and the button on the slide disappears and we move to the next slide - perfect.
So then I add the following next - exactly like I did in the beginning:
Code:
var goBtn:MovieClip = new FeatureButton();
features[featureCount].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
This time adding it to the current slide coming in - but this generates the following error:
Code:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at featuregallery_fla::MainTimeline/nextFeature()
How I'm getting an error on the removeChild() when that is already gone. I assume "parameter child" means goBtn - yes it is null because it's been removed. But I'm not trying to do something with that. I can only guess this is a variable scoping issue with goBtn - but I'm not seeing how to resolve it. Flash file attached.
I'm binding an array of items to a data grid using ItemRenderer. I use the data variable to control the bindable data. I also have someComponentVariable that need be inserted into every row but its declared at the component scope, so the data grid doesn't seem to reconize it (compile error). How can I use this variable (someComponentVariable) inside the ItemRenderer?

You will find enclosed a ".zip" file in wich there's a ".fla" file, a ".txt" file and 6 ".jpg" images. Frame 1 of the FLA only has a "Preload" class/constructor found on another site and works well. Frame 2 launches the graphic interface construction. The file "externalVar.txt" has one variable "maxVin" with a value of 6.
I would like to know WHY i can't acces this variable from outside of the loadVars object's scope (i would better say from outside of its ".onLoad" methode scope). In fact, when i trace my variable "maxVinNum" from outside of this function, flash player return "undefined". Even if i declare "maxVinNum" on the _root (_root.maxVinNum). For information, at the start of frame 2, i have let an instruction in comment: //var maxVinNum = 6; When we activate this instruction, then the variable is directely declared and everything works well. This test allow us to verify that scripts are not bugged. Here is the script of frame 2, some of you may understand quickly what's wrong :

In the code below, I'm looping through nested xml structure of an unknown number of levels. GenMenu is (or will be) a recursive function that will build each level of the menu. My problem is that I can't figure out how to reference the variables from an eventlistener function. I need to pass the children node_xml[i] to the next recursion, as well as set hover styles on the menu links, etc...
Code:
function GenMenu(container, name, x, y, depth, node_xml) {
// variable declarations
var curr_node = new Array();
var curr_menu:MovieClip = new MovieClip();
addChild(curr_menu);

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

I have 2 class. Main class and a subclass (being an image loader).When the subclass has finished loading I want it to access a timer function in the mainclass.Code: Select all1)mainclass |> subClass.loadMe();2) When subclass load finished.3)Subclass |> mainclass.startTimer();This i dont know how to do.
View 2 RepliesHow 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.
I have 3 files.
main.fla
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 {
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.
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
{
[code]......
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?
