ActionScript 3.0 :: Make The Positioning Inside The Class?
Dec 28, 2010
Today i tried to attach a movieclip using AS3, but i wanted to make the positioning inside the class.
And i obtained an error: First file(Document class)
PHP Code:
package
{ import test;
import flash.display.*;
[Code].....
At sequence mc.q=Math.random()*100; in the trace from test.as it displays 'NaN'. How can I modify the value of 'q' (public variable) via instance? If i use a function like mc.setCoords(x,y) the script works fine.

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(){

PS: What is the syntax for using AS2 code tags instead of just "[CODE|"?

This is a webpage, where I use a modified gallery from tutorial (xml galllery with thumbs).This place is where I align picture movieclip in the center of area (which is also a mask).Sometimes, action clip doesn't get image _width and _height and load a picture with it's left upper corner in the center of mask movieclip. When I click again on thumbnail - image loads already perfectly how it should be centered. What can be the problem? maybe I missed something?Here is a modified code of the gallery:
Code:
stop();
function loadXML(loaded) {

How do I position the arrows I've placed inside the TileList so that they point from the center of the TileList object and towards the border of the TileList object?
Currently, they're positioned in the top-left, and they points toward the expected direction. Because they're positioned incorrectly, it doesn't look good (See submitted files)

I have the positioning for a movieclip set via _x and _y parameters. It works fine when I publish and test just that flash file with the movieclip in it. Problem is, this flash file is embed inside another. Once I load the main flash file, the _x and _y are relative to that parent file.

Take this class:
package {

Why does the following code not move the created circle and how can I make it do so?
var s=new test(stage)
s.x=500

I'm using Flash CS3 to build a simple drawing application. When the user clicks a button, they select a particular movieclip. After clicking elsewhere on the stage, the clip is instantiated and added to the stage at the position of the cursor. I've also added the option of being able to click on the added clip and drag it around on the screen. And this all works fine.
The problem is that I also want to be able to dynamically draw and add objects to the stage via the Graphics class. Whenever I add objects in this manner, their x and y coordinates are always 0,0 no matter where I place them on the stage. This makes positioning these graphics very very problematic. I created a modified positioning function specifically for these dynamically drawn graphics and while it does "work", it feels less responsive than the positioning for movieclip objects. I'm still trying to optimize this function, but it seems to me that the ideal solution is for the graphics to have non-zero coordinates when placed in the middle of the stage like movieclip objects. Is there some "workaround" to achieve this?

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:

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.

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 have built a basic preloader that runs in my document class. I'm having trouble with it.I'm guessing its due to what a class can and can not access from the stage?theres 2 problems. the first is that I cant change the keyframe the stage is on from the class. the second is im getting an error 1009 if I comment that out.

I'm having a problem where I can't make an instance of a class in one class like I can in other classes all in the same package. When I call the update function from another class it doesn't work. I traced the xPos of the instance of the class I was talking about and I get zero, but that is incorrect so I'm thinking it's the above problem. If anyone knows what the problem is please tell. Here's my code:

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]

How can I use LoadVars inside a class?I mean, if I assign the method name to onLoad of LoadVars, the method will be override, and will not pertence to my class.look this:
[AS]
class myClass{
var lv:LoadVars;[code]...
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 I will face the same problem with all others components that does not has addEventListener capabilitie.

Take a look at these example:

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.
