Actionscript 3 :: Creating Classes And Properties?
Aug 28, 2010
I'm new to AS3. Learning how to create classes. Is comp = new HouseObjects creating a new class? Is comp creating an instance of the HouseObjects? I realize that this is inside public class TreeHouse. I'm thinking that HouseObjects, how I set it up is not a class...not sure what the correct way to set up classes and properties.
Also I noticed, that when I tried to link another movieclip using the same linkage name HouseObjects--it asked to enter a unique class. I'm trying to create multiple instances from the same class called HouseObjects.

I have a class which extends the Proxy class, and has a statically defined member variable called num:
public dynamic class TestProxy extends Proxy
{
private var num:Number = 100;
[Code]....
I want getProperty() to be called when I attempt access num. It works for any field which does not already exist, but not for fields that are predefined.

Im building a project using an MVC pattern. I have (pseudo) abstract classes Model and View, each extended with particular models and views. But I cannot access properties on the extended classes of Model...Model simply distributes XML data, heres its constructor:
Code:
public function Model(data:XML)
{
_data = data; /*_data is a protected var of type XML in Model*/
}
MainModel extends Model, and has a property called _background of type Background which also extends Model:
Code:
private var _background:Background = new Background(some XML source);
public function MainModel(data:XML)
{
[code]....
The problem arises when I try to pass MainModel's background property as a parameter of _bgView (highlighted in red above). The compiler says there is no background property on Model, which is true, but I need it to look at its extended class MainModel, not Model. I've typed MainView's constructor parameter with MainModel, but it is still seeing it as Model.

I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.

i am using get and setters in my as3 code to edit values of an other class (because those variables are shared) i dont like to put stage.sharedVar.isScrabble in my code every time to change a variable so i used get/set functions [code]as you van see it has a lot of duplicate code every time the "return stage.sharedVar." and the "stage.sharedVar."+ the value + " = val" is constantly comming back.i was wondering is there a other way of creating these get/sets?[code]

Back in the day (AS2), I used to create what I called an"ivar" property that collected the index of a series of buttonsthat were clickable (see attached code). Imagine 10 buttons on thestage with names (selectButton0, selectButton1, ...selectButton9).The code under the //----------BUTTONS header would make a propertyof the button that was clicked, call it "ivar" and then send it upto a function that would use it as an index to then load theappropriate content with MovieClipLoader (remember that Class?).I have tried something similar in AS3 without any luck sincethe whole button thing is now steered by events. Does anybody knowan elegant solution that would achieve a similar result. That is,click a button called "selectButton0" and have returned the zero asan index variable that could be used further?

I am trying to create 6 TextFields with a loop which I have done but I can't seem to figure out the right syntax for setting the properties such as font, size, etc. in the loop. Here is my basic code:
var Tiles:Array = new Array();for (var i:Number = 1; i< 7; i++){Titles[i] = new TextField();
Titles[i].TextFormat.size = 17;}addChild(Titles[f]);}

I'm new to flash, as3 and this forum so any help would be great!I've made an xml gallery, all the movieclips and everything have been created dynamically and the images are being loaded through an xml file. Except two buttons which are in the library and have the linkage names next_btn and prev_btn.
Now what I want to do is, I have 3 categories of galleries, so I want to convert my script into a class which I can use for every type of gallery. (I hope I'm being clear)When the user clicks on gallery, a the function startGallery() is called.
I need to know how to go about it I'm pretty much clueless, I've read a WHOLE LOT of tutorials about classes but I really can't understand how to do this.

I want to know how to create a tween so that at start of it my movieclip called myBox will be at say 6 blur on the x and y. Then at end of tween it is at 0. And I need to be able to say how long it goes for. I have a tween already that makes it move, that was easy but making it blur as well isn't easy. How to do this?

I know this is possible because I've seen it done somewhere or other but I have no idea what it is called. Quite simply, I want to create some dynamic classes without having external .as files for each one - I just want to declare them inside a function in my doc class.

I am attempting to use multiple AS3 timers to run a short animation in flash but I'm having a problem with some of the instances running slowly or not being removed when they are supposed to. I found a way to make things work the way I want but in being new to AS3 I believe my runtime issues are due to jumbled code.
import fl.transitions.Tween;
import fl.transitions.easing.*;
var playerFadeTween:Tween=new Tween(thewebs, "alpha", Strong.easeOut, 0, 1, 2, true);
var playerXTween:Tween=new Tween(thewebs, "x", Strong.easeOut, 292, 10, 2, true);

I've always wrote all my code into the .fla and now I'm trying to use classes more. I have my file loading the document class. Then the document class imports two additional classes. In my constructor of the document class I am creating a new instance of both additional classes. Here is my doc class:
[Code]...
Now inside of the other two classes I should be able to just use main_class.myFunc(); Correct? Why isn't is working? How can I interact classes? If I create a new instance to the class I want to access then I get a stack over flow error. Inside remoting class in the constructor my code; main_class = new CheckoutMain(); main_class.myFunc();

I'm making a game which loads map .swfs at runtime. The maps will contain graphics and code, which can both vary from map to map. I've decided to make all the maps implement an interface, so they can all be used in the same way by the game. I'm using a .swc to contain the interface, like in this page.
I can get classes to work in the .swc, but not interfaces!
I'm using Flash cs5, and flashdevelop for editing, in AS3. Here's how I've been doing it:
1- create map.fla with a symbol called Map, and a Map.as:

I am starting to create classes instead of using the timeline and I am learning a lot more even if mistakes happen more often. However I have a question about linkage & library. For example let say that I have a ball pic called Ball1.mpg. I copy and past that Ball1.mpg in my folder where the Fla file is as well as the as file. If I want to utilize this Ball1.mpg in my code using Flash do I absolutely need to import into my library and link it and export using linkage? Or can I use the object Ball.1mpg just using actionscript. Of course that implies that I would use an actionscript class not the timeline.

I've been trying out small snippets of code just to practice with and get comfortable with making classes and small games.Right now I am trying to make a simple combat with Orks. Where there is a Parent Class ORK with several ORK children classes like SentryOrk, MetalOrk, etc.
The Ork class basically puts in the many stats used by the ork such as health, strength, vitality, special, luck, etc. And then the children classes modify those like Sentry Ork will have less health and more luck.I did all that fine, but the problem I have is I want there to be multiple Sentry Orks out with their own defined stats.Right now whenever I do initiate the attack one out of three orks on the screen, they all share the same health.I know what the problem is, I just don't know how to go about dynamically making each class their own?Do I have to make a whole other class to bring them onto the stage with their stats like create a new class that handles all ENEMY POP UPS? I don't see how to do that either?:

I have created a file called Config.as, in it are getter and setter methods that define variables that I need to reference throughout my system.
I have obviously made a mistake as I tried to access a variable in two files as indicated in a demo below:
Code:
package {
import Config;
public class TestOne {
[Code].....
It seems quite clear to me that I have created two instance of the Config class and that is why in class TestTwo the trace statement doesn't return "hello world". Is there a common coding practice to access the same variable with multiple classes?

I have a designer who has created a set of movie clips that I want to create instances of using ActionScript, but all I have is the name of the MovieClip as it's stated in the library (not the instance name).
Is there any way to create instances of the MovieClips using just their name? Or do I have to create separate classes for each?

Are there any tutorials available that will show me how to create a multiple class program from scratch? I have 2 classes working with a fla and when I add a 3rd class every object I create comes up as an error.1120: Access of undefined property.I'm very frustrated cause I can't figure what the problem is. I have just migrated to OOP so I'm relatively new at this.

am creating a simple flash game where you rotate a planet to make the buildings on the planet avoid incoming meteors.I was told that there is another just like it already, but I don't want to see it because it may restrict my imagination.
I have everything pretty much planned out now in a "game script" of everything that i want to happen. only thing is, i'm not sure where to start.Actually,i implemented rotating the planet and the timer so far, but that is all.I was wondering if anyone wouldn't mind reading through my game script and pointing me in the right direction.I am trying to wrap my head around creating classes to handle different aspects of the game, but not sure what to put in a class and what not to.I attached the game so far and the word file

When I create anything in a library, it's basically a class right? Meaning I can do essentially the same thing with use of a package in an AS file? In AS 2.0 this would probably mean I can add specific functions on this class as I can do when I use flash's object interface and add script to the specific class object itself. However, in AS 3.0 you cannot attribute code directly to an object right?
This leads me to my second question. I basically want to create a flash mp3 player (I've coded this already), but make it so that it is an entire package of contents, so I can add it to my website when a mouse event is detected and then take it off the website once it's no longer needed (to conserve memory and assure an overall nice experience). The problem is that I have many objects and subsequent functions (play button, pause button, etc), and want all of this to be contained in one file. Is this even possible?

Just been playing around with the tutorials, on the Set properties/Get properties. Everything is all cool, except the "instance name" aspect. I dnt really understand that too well. Is it possible to change an Mc Name dynamically? If you look at my FLA when you hit the top left red button you will get a trace of the mcName as "square". Now if you input a new mc Name on the right hand side, you will see it change on the left hand side. But i want to know why it doesnt remain as the new mc Name, it still goes back to square.
