ActionScript 2.0 :: How To Use LoadVars Inside Class
Feb 18, 2004
I mean, if I assign the method name to onLoad of LoadVars, the method will be override, and will not pertinence to my class.
[AS]
class myClass{
var lv:LoadVars;
function myClass(){
lv = new LoadVars();
lv.onLoad = onLoad;
} function onLoad(sucess:Boolean):Void{
trace(this);
} function trigger(){
lv.sendAndLoad("testeURL",lv,"POST");
}}
This at onLoad function points to loadVars not to myClass. The only solution I found to this was to myClass extends LoadVars, but it limit me since AS 2 does not support multiple-Inheritance. I think the same problem with all others components that does not has addEventListener capabilities.

This code is being run from a frameset in IE8. When the new window is opened, the form data is not being recognized. It appears that the http header, "content-type: application/x-www-form-urlencoded", is not being passed into IE and this is causing the post data not to be processed. The data is there, IE is just doing nothing with it.
This code works fine in FF and Chrome, and in fact the correct headers are passed in FF and Chrome.
NOTE: The new page is on a different site, but i don't know why that would cause a problem with a POST and not a GET.
Flash code:
varSender = new LoadVars();
varSender.title = _parent.tCourseTitle;
varSender.notes = input_txt.text;
varSender.send("http://example.com/notes/print.cfm", "_blank", "POST");
I have tried adding the header to the send request, but that has no effect at all. The contenttype header is still missing and it still works everywhere but IE.
My current work around is to use a GET instead of a post, but that's ugly and it limits us in the size of data we can pass but for now at least it works.

I have this fully functioning program with me that has a certain line of code that I am having a little difficulty figuring out. Here is how it goes:
Code:
var initVar:LoadVars = new LoadVars( );
I know what the above line does, as in a variable 'initVar' of type LoadVars is being decalred. It's a composite datatype and LoadVars is a class.
However what I don't understand is what comes next:
Code:
gBasicConnect = initVar.basicConnect;
I was expecting basicConnect to be a method of the LoadVars class, unfortunately according to the AS2 API, it's not. Where could basicConnect have come from than? The program was originally written with ActionScript 2.0 in Flash 8.0, I am now looking at it in CS3.

I'm building an external class file that other developers can use to include a set of functions that essentially read and write data to MySQL via PHP.
The idea is that their AS2 script calls a method in my class which uses LoadVars to verify the data passed to it and write it to a database, and then it returns a value back to the AS.
I'm having a problem where the delay in waiting for OnLoad means that the calling AS function gets an undefined value back. i.e.
var returnValue=myClass.myMethod(params);
This (I assume) is setting returnValue instantly, despite the fact that LoadVars can take a little while to work.
What's the recommended/normal way to deal with this? I don't want to have to bring the OnLoad part of the process back into the developer's script, it would be nice to keep it all in the class. is there a way to make the calling script wait for a response?

One of the moderators, could you've a look at this tutorial: [URL] it doesn't works with me, maybe because I've 2004 so if you change loadVars() into LoadVars() it should work

package{
public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt
[Code].....
I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?

Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?

i have a BasicMap.as that takes an Array and populates itself with the MC objects passed to it by a String reference.it inherits from Sprite, and so it just places the objects on its self.then i have a class that inherits from that class, and gives a little more functionality to it, but in order for it to do that, it needs to place the objects not on itself, but instead inside a holder Sprite, so here is my problem:
code:
package Mushroom{
import flash.display.Sprite;

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 want to know how to make class instances into listeners and broadcasters, from inside each class. Here is what I am trying specifically... part of the Proj class... (projectiles, as a matter of fact)
Code:
private function listen():Void {
u.register(this);
onUpdate = function(){
step(); // a function I have which makes the projectile move (not shown)
}
}
where "u" is another class, the Updater class with this code...
Code:
class Updater {
// const. --- make this a broadcaster
public function Updater(){
[code]....
PS: What is the syntax for using AS2 code tags instead of just "[CODE|"?

This is what i'm trying to do :
I have 1 class that extends movieclip, let's call it Class0. I have 1 class that extends movieclip, let's call it Class1.
I create an instance of Class0 on stage like : var myClip0:Class0 = new Class0(this, "Class1");
The class Class0 when initializing, will create a new movieclip (myClip1) and add it as child, as an instance of Class1, like myClip0.myClip1. But it's when i create that clip, i want to tell it, it's an instance of Class1, like :
private var myClip1:Class1 = new Class1(this);
Where Class1 could be any class.
How do i pass Class1 to Class0 so it can create it dynamically?? Do i have to use the apply function??
inside Class0, i have a function that does :
Code:
if(subClass){
initSubclass(subClass);
}

I am very new to flash and on the net I've found a class that allows me to use a nice scroll bar for the content. My problem is that I can't get a preloader working with the class. When I want to add scrips to the frames it bugs the class if I try to implement the preloader inside the class I can't get it working. Here's the class I am using for the scroll bar. - if you want to test it, it will require additional data. You can get it all here: [URL].
package{
import flash.display.*;
import flash.text.*;
import flash.events.*;
import gs.TweenLite;
import com.warmforestflash.ui.FullScreenScrollBar;
public class Main extends Sprite{
[Code] .....
If I try to insert the preloader script inside the class it has problems with the stop(); & play(); commands. Any way to get a preferably simple preloader working with the class I am using?

I have a private class variable that is an array. I have the getters and setters like I would for any other variable. When I push something on to the array from outside of the class using the instancename.arrayname.push() it pushes it onto all of the arrays of all instances of that object like it is a static variable or something.

i am not very clear what is the difference if you are using this and if you are not.[code]In php you have to use $this to access class properties. But in actionscript you don't.In AS you can trace testVar using this or without it like this:[code]

Take a look at these example:
Code:
function loadMap():Void {
varxdata:XML = new XML();
xdata.ignoreWhite = true;
[Code]....
Now, im creating a local variable var var_temp:String; cause, there is no way that i can pass the values, inside the onLoad handler to a property of the class.
If i try some this.some_var its reference to escope inside the onLoad handler..

I have created a class file with 2 functions one to load an xml file and the other to parse the file and push the values into an array. My problem is that I can't access this array inside another function unless pass the array as a parameter or the main timeline. Below is the class file I'm using:
Code:
import mx.utils.Delegate;
class XmlTest
{
[Code]....
What I would like to do is pass the array to another function in the class file. This function would loop through the array and push certain values into an array that would be returned to the main timeline so I can using them.

I'm just starting with as3 object oriented programming -- i've always liked the idea, but could never "see" how the whole objects/classes worked with actual game development.in my fla file i have this...
Actionscript Code:
var moveBob:MoveMan =new MoveMan()
in my MoveMan.as file...
Actionscript Code:
package { public class MoveMan { public function MoveMan() { bob.x = 5 } }}
and on the stage i have a movieclip with the name set as "bob" If i use this line in my fla file... bob.x = 100 it works.But when i try to move the movieclip inside the class i get this.1120: Access of undefined property
