I have four movie clips in my library that are defined as classes: Option0, Option1, Option2 and Option3. I have four buttons that pass a different value from 1-4 to a function. I want to add the clip to the display list that relates to the passed value. In AS2 it would go something like:this.attachmovie["option"+currentVal, "newOption", this.getNextHighestDepth()];

I'm building a simple Pong-esque game and I've 'hit' a problem. I'm having an issue with referencing one variable from one class into another. Sounds confusing to me, even harder to understand.
Basically I've got this in my "game.as" class:
ActionScript Code:
public var pongBall:ball;
and in my "player1.as" class I am trying to get said ball to bounce off the player's bat on contact. I think I have the coding right for it apart from trying to link it to the ball from game.as! So far I have this:
ActionScript Code:
public function bounceTest (event:Event) {
if (this.hitTestObject("game.as".startGame.pongBall)) {

Long time ago I've been creating some as 2.0 projects, all of them based on the code within the timeline. I wanted to start learning as 3.0 based on classes rather on timeline but I find it confusing and difficult to understand introduction into the classes. I can't get to understand why the following example is not working :
I've got 3 files:
main.fla with main class "Main"
Code:
no code
Main.as
Code:
package {
import flash.display.MovieClip;
import projectconfig.Configurator;
public class Main extends MovieClip {
var projectConfigurator:Configurator;

Before this application runs, I have to do some basic intialising - load up some stuff, build the display list, check I've got the right xml, wire a few objects together. I'm used to doing all of this stuff in the constructor of Main() - my main application class, but it gets a little unwieldy. Would there be any mileage in offloading this into a command class? Is that common practice? I was thinking that way all that Main() would have to do is just listen for events and manipulate methods of the other main classes. The only thing that concerns me is that Main needs references to the main classes and to add event listeners etc. This could be tricky if it's all set up in a command...
View 1 RepliesI'm trying to make a dynamic menu. I load four buttons to the stage and applie code to each of the buttons. But it's only the last button loaded, that responds to onRollOver/onRollOut If I roll over the other buttons it's the last buttons that reacts all the time. I just can't see what's wrong. I'm sure it pretty simple. Here's the code:

Been trying to make the transition from AS 2 to 3 but not without it's speed bumps. My first major hurdle has been trying to dynamically reference a class by only knowing it's name. I came across the code of import flash.utils.getDefinitionByName; but that's not working for some reason. It keeps giving me the error:
Quote:
ReferenceError: Error #1065: Variable characterType5 is not defined.
My code in getting this is:
PHP Code:
import flash.utils.getDefinitionByName;
var className:String = "characterType" + 5;
var tempClass:Class = getDefinitionByName(className) as Class;
var char = new tempClass();
I'm building an application where it would be sweet to use dynamic instantiation of Classes.I'm using "flash.utils.getDefinitionByName" to get this done and, if I instantiate the Class in my code once, there is no problem at all.But, I want to be able to do this without instantiating the Class at least once before I go with the getDefinitionByName method.I'm using Flash Develop and the Flex SDK, coding with pure AS3.Is there any way to instantiate the Classes only dynamically?Or, any alternative to the getDefinitionByName method?

or are there functions you can't build in external as but you can in the IDE?
I'm making a program so that you can plug in your birth year and get some basic information on what Chinese year you were born in (Year of the Dragon etc).I created a class, linked it to an MC and looks like it is creating everything okay but the input text is definitely buggy.I can input text at the top of the stage but not in the actual text field.I have spent a lot of time on this and am completely clueless as to what is bugging this thing out.I guess I am not declaring something properly but I've had my TA take a look at it as well and she cannot figure it out.

View 1 RepliesFrom what I hear, getting/setting dynamic properties is a lot slower than regular properties.
But does allowing a class to be dynamic slow down the entire class for regular property getting/setting?
For instance, let's say I have this class (pretend those properties have setters as well):
Code:
public dynamic class Hero
{
public function get endurance():int
{ return _endurance; }
[Code].....
Obviously, calling and setting the "magic" property will be a lot slower, but will all properties become slower to get/set just because the entire class is set to dynamic?
Is it better to not set the entire class to dynamic, and instead create a new dynamic object, "additionalStats" where properties can be get/set to instead?
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 was wondering best practices for views of inherited classes in PureMVC in this situation: Multiple classes inherit a BaseClass (lets say InheritedClass1 and InheritedClass2) Each InheritedClass has a respective view (derived from a base view class, but each unique) With a given dataset (lets say ArrayCollection of InheritedClass1/2 Objects), the respective views need to be dynamically loaded. The dataset is relatively large, so a TileList would be nice (since it only instantiates objects which are currently displayed) I can think of a couple solutions, but I find them to be too "hackish" to be the best solution:
In View: Repeater over a BaseClassView which attributes a view to a State (set to the "InheritedClass1" state to add a InheritedClass1 object) Pros: No unneeded memory increase (States' objects are instantiated when needed) Cons: View is dependent on the data types, so adds coupling In Mediator: Loop over the ArrayCollection and addChild() the views based on data type Pros: Works. Cons: Mediator is adding things to the View, which defeats the point of the separation of Mediator and View. Slower than a Repeater.
The sound I wanted to stop or play are separates into background music and button sound effect. I know you could use SoundMixer.stopAll() to stop all sound, and some how exclude the bg music, IF everything is written in the same class. But what if the sounds are called from others dynamic classes? How could I target them and exclude the bg Music?

I created the code below which works as it should using the main timeline actions in AS3 - now, for my project I need this to work in AS3 using class files (basically I'm creating an app which uses pages as class files. This is intended to go on the 2nd page.for some reason though when I've copied it into my project and instantiated it when the page loads, even though all traces say that the squares should be there - they are not! The best I've had so far is one square in the final position![code]
View 0 RepliesIs there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I'm writing an application where I have many objects (data models) that are identified by a unique String ID that every such object possesses and these objects can refer to each other by their IDs.So far so good but now I need to keep track of which object keeps a reference to another object and of course there are cases where an object references (or is referenced by) more than one other object and I was wondering what would be the best method to store these references? In a simple map data structure I could just map one object's ID to another but as mentioned there are cases where an object can hold a ref to an arbitrary amount of other objects

View 1 RepliesI'm using the CSS object (TextField.StyleSheet) to format my dynamic text, which is loaded from an XML doc. I tried referencing more than one class, like <span class="body bluetext">. However, it doesn't seem to work because it ignores the first syle(s) and only applies the last one in the list. I'm guessing Flash doesn't support this (since they're CSS support is already very weak). Just want to make sure I'm not doing something wrong.
View 0 RepliesLately I've been twitching in the back of my head wondering just how many references to objects that I'm making, and whether or not they are getting GC'd or not.My question in this sense refers to event listeners and whether or not they are removed in certain cases where you get rid of an object. Two examples:
First, and I think this one is an easy one... when you create an object that adds an event listener to itself INSIDE it's own methods (e.g. this.addEventListener(e:Event, function)), when you REMOVE that object (this), do it's event listeners disappear too? I can only say yes, because they are referencing THAT object and are INSIDE that object.
So I think that question answers itself (but I'd love to know if the truth says otherwise).
But secondly, if you add an event listener to an object from a sibling or parent object, and then remove the object, does that event listener stick around, therefore maintaining a reference to that object and keeping it in memory? And is that the concept that people keep referring to of 'weak' event listeners? E.g. someChildObject.addEventListener(e:Event, function)Also, are event listeners by default strong or weak?
And I am assuming that 'yes', it DOES keep the reference. Which, if you are a n00b programmer like me, you probably are all like, 'aww sh*t damn, how am I supposed to make sure that my objects are getting thrown in the garbage collector's mouth of goodness every once in a while?
I have a files that has movie clips and nested movie clips on the stage. I am now writing a class and want to give the MCs event handlers and other properties.
When I do something like the following: myMC_mc.MyOtherMC_mc.mouseEnabled = false;
I get the error: 1120: Access of undefined property myMC_mc.
I added this to the top of my class and it seems to take away the error, but I thought this was not needed in AS3 anymore.
private var myMC_mc:MovieClip;
private var myMC_mc.MyOtherMC_mc:MovieClip;
What do I have to do to not get the error? How is this done right?

I've got a 15x3 grid of dynamic text fields in an object called "textbox" that I want to reference through a for loop, so I don't have to have 45 lines of code for assigning stuff to those fields.I have each dynamic field named by their placement in the grid, so, c0a, c0b, c0c, c1a, c1b, c1c, etc.I can also name them c00, c01, c02, if necessary.
I tried:
for (i=0; i<15; i++) {
textbox.c[i]a.text = "Cell " + i + " A";
textbox.c[i]b.text = "Cell " + i + " B";
textbox.c[i]c.text = "Cell " + i + " C";
}
but that gives me a syntax error.I also tried naming them c00, c01, c02, c10, c11, c12, etc., so I could do a double nested loop:
for (i=0; i<15; i++) {
for (n=0; n<3; n++) {
textbox.c[i][n].text = "Cell " + i + n;
}
}
but that gives me a syntax error too.So, is there a way to access all of these with a for loop, or am I going to have to do it the long way?
