ActionScript 3.0 :: What Methodology Use In General When You Want To Make A Custom Class Object?
Jan 4, 2011
new to ActionScript 3 and while I'm trying to write as "clean" code as possible (creating various custom classes instead of everything in the document class for example), sometimes I stumble upon behaviors that would not arise if I had put everything in the same place.I have a project which involves fireworks which is working fine, but I'd like to add a smoke trail to the rockets (a custom class rocket object) and so far I can't get it done.
So I will ask my question first: what methodology do you use in general when you want to make a custom class object leave a trail of particles behind it? Do you include the trail generation in the class? in a separate class? on the document class?what I've been doing (and what I feel is the "cleanest" and most reusable way to do it) is to put the trail generation in the custom class rocket object. This object is just composed of some graphics and the function that generates the particles(which are another custom class).The actual handling of the firing and the movement of the rocket is done by the document class.So the problem I'm having is that when I generate a particle on a frame, if I add it to the rocket object, it follows it (local coordinates), and if I add it to the stage then I can't remove it from within the rocket object...

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I have written a Class for skinning the UI. The Class works by taking a movie clip name from the stage passed to it and create the skin for it.So I create an Object from the class such as this:
Code:
var CBox:UI = new UI();
Now what I wanted to do is reference a movie clip from the stage to this CBox variable, so when a call the Class methods it will know which movie clip to work on! Since currently I have to do this:
Code:
CBox.Skinning(content_mc, "content", 100, 200);
or
CBox.Over(content_mc);
As you can see Im passing the movie clip, content_mc, everytime. I just want to avoid this by creating a reference.

For the game I am making, I'm using a self-made sprite managing system.I've got three classes: SpritesManager, SpriteGroup extends Movieclip and Sprite extends Movieclip.The idea is: SpritesManager is holding an object: "mainSprites", SpritesManager also hasa method "newGroup", wich creates a new SpriteGroup in mainSprites.In this way I want to make a system for creating and managing some sort of Movieclip-tree.For example:mainSprites.enemies.badEnemyThe method newGroup in SpritesManager has a param "name" wich is the name of the SpriteGroup to create.Here's where I'm stuck: how do I create a new SpriteGroup referenced to as "name" in mainSprites?

I've created a custom class to represent a monster in a game. The class definition has "public class Monster extends Object". I'd like to know if there's a way to initialize the object using object literal notation. For example, this works ok:
[Code]...
I get this error: "Implicit coercion of a value with static type Object to a possibly unrelated type Monster." Is there a way to do this? I'd rather NOT have to call the Monster's class initializer each time, because in the actual code there are a lot more variables in the monster class than just those three, and it's kinda unwieldy to pass a dozen long strings into the new() function.

I have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...

I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule

The following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.

I am programming a web based application with Actionscript 2.0 classes for flash 8, and I want to save user data using the local shared object.As the data is potentially rather complex I would prefer to store it in an instance of a custom class that I then stick in an array property of the local shared object data property.However, when I try to do this, if I retrieve the stored object it seems to have lost all its instance methods. If I do a for in on it, I can see the private properties to which I have assigned my data, but as they are private I cannot retrieve them.how I can store an instance of a custom class in a local shared object without it being corrupted in this way?

I followed the example from a previous question and I am loading an external swf using a loader and inside the loader event handler I am trying to cast the loader.content as my custom class PanelReferenceClip which extends MovieClip
When I publish I receive a this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Just to make sure and test that the swf location was correct and the swf was actually being loaded, I changed the type of the content to as MovieClip and it worked fine.
EDIT: I also wanted to add that these swfs are being stored locally and not being pulled across the internet, multiple networks or servers.
I am not sure if I did something quirky in my class so I am providing the source to my custom class PanelReferenceClip
package com.components
{
import com.UI.DevicePanel;
import flash.display.MovieClip;

With MXML components, I've seen a pattern used where you have an AS3 class, then the MXML subclasses it, to have a separation between view/code (anonymized from real code):
package com.john
{
public class MyComponent extends Canvas
{
[code]...
At least I think the MXML component is subclassing the AS3 class?Anyway is it possible/advised to do this with my main MXML application file, so I can put manager instances and things in the AS3 MyApp class, which is subclassed by Main.MXML?

I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);

I am still quite new to AS3, but trying to learn the essentials. What I have trouble with is this:I have a box on the stage (or frame 1 in timeline). Inside this box I made a dynamic textfield. I made a movieclip of these two together and called it watch (instance name). Also exported to actionscript with name of the class StopWatch. Now, in actions in the timeline I do this:
Code:
import classes.stopwatch.StopWatch;
var atch:StopWatch = new StopWatch();
