I really like the fact that dynamic features are available in Flash, despite their slowness.With that said, is there any way to "auto detect" when a new property is being added to a dynamic class?I'd like something along these lines:
Code:
public dynamic class Detector extends EventDispatcher

I got a Website.as file that loads 4 library's movie clip's on the stage in certain positions.. Clip_A Clip_B Clip_C Clip_D
Clip_A loads on the top left side , Clip_B on top right , Clip_C in Middle and Clip_D low right position.
What i need to do and understand is how can i tell that class to find a button inside Clip_B and play a certain frame in Clip_C?
I am making a video player class that will be imported as a custom class into a fla (not document class). how i can add clips to the display object without having to return them from the class?
is there something like stage.addChild or root.addChild or something that i can use?
i have a question while reading Flex 4 Cookbook i came across the method to dynamically adding control to the container controls but nowhere i came across with how to provide them with the dynamic properties and events like they have created a button dynamically inside a group control but what good a button be if i cannot give it an event dynamically. in the same way i want to add a tree view inside a vbox but what good that be if cannot provide a data provider to it dynamically.actually i am creating an web application where i add the tree view to a vbox and i want to the data provider should also be dynamic depending upon the option i have selected in the combo box.
View 1 RepliesBeen 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?

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()];
View 3 RepliesI'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.

From 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?

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!

View 0 RepliesI am trying to:
1) create a dynamic property
2) bind that property to a label
This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered. Are dynamic properties implicityly not bindable?
var myObj:MyType = new MyType(); // MyType is dynamic
myObj["myDynamicPropertyName"] = "initialized";
BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name);
// myLabel now displays "initialized"
myObj["myDynamicPropertyName"] = "changed";
// myLabel still displays "initialized", it should say "changed" !!!
i have some simple html links wrapped in a div id called 'contentOpen', some javascript listens out for when links wrapped within the contentOpen div are clicked and then calls a function called 'click' (which is within jquery.js)
i want to be able to use a flash button to do the same thing - how would i modify my flash and/or javascript to be able to do this ?
here is my javascript:
$('#contentOpen a').livequery('click',function(){
// capture the url to load from the href
var urlLoad = $(this).attr("href") +' #content';
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href') .length-4);

I am using LoadVars to import text from an external .txt file into a dynamic text box, and although I can create simple hyperlinks (using <a> tags) within the box that can redirect the current page to a new URL, is it possible to have links which work within the flash movie - i.e. navigating to another scene?
Is 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?

View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
Could anyone give me a good use case for ActionScript dynamic classes? Because it really looks like a bad pratice, for me, in every case.
