In AS3 I can use interfaces to declare required methods of a class, so that implementors throw a compiler error if the method does not exist.Is there a way to get similar functionality for properties? In other words, make it so that a class using a certain interface must also contain certain properties, not just methods?
View 1 RepliesI have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
I have a XML schema.I want to read only table tag and its geometery tag using action script3 code.Any Idea.
<table name="TableBase 1" id="TableBase3010" overflow="false" direction="lr-tb" suppress-empty-lines="false">
<style-ref name="default"/>
<geometry size="absolute" position="absolute">
<location left="117" top="102"/>

Consider this for a second:
Code:
theState.stateGrowth = 0;
globalVariablesArray.push(theState.stateGrowth);
trace(globalVariablesArray[0]); // traces 0
theState.stateGrowth--;
trace(globalVariablesArray[0]); // still traces 0
Is there anyway to make it so that globalVariablesArray[0] always contains the 'new' value of theState.stateGrowth, even if it changes? In other words, store the property itself in the array, not just the value of it?
I'm currently trying to make a class that changes the mouse cursor. I made it in a new class so that I can call it again whenever I needed it, but there are some errors and I don't know how to solve it. The class filename is Cursor. This class is not linked with the fla file.
Here's the ActionScript Code:
package {
import flash.events.MouseEvent;
import flash.ui.Mouse;
import flash.display.MovieClip;
public class Cursor extends MovieClip {
public function Cursor()
[Code] .....
This class will just let me type Cursor.makeCursor(cursorMovieClip); and the cursor will change. The problem is that Flash does not recognize "addChild" and "stage". Is it because the class isn't connected to the fla? Or do I need to import some stuff in? Also, flash does not recognize "obj" in the code line
ActionScript Code:
var cursor:MovieClip = new obj;
In As2 i was used to just being able to put for example: Apple = House
and when i typed Apple As2 would see it as House, im trying that in As3 and it says "Undefined Property" which is obvious but,how would i be able to do this in As3? could i possibley make this a Variable? if so which do i use kind of variable do i use? Example: :Number:Boolean etc
this should be easy, but I can't figure it. How do I get an XML declaration in AS3? I need to get any encoding= parameter. For example this XML:
<?xml version="1.0" encoding="UTF-8"?>
<some>
<thing>...</thing>
</some>
It's XML text that loads externally from a URL using URLLoader. I create the XML object by doing var xml:XML = new XML(evt.target.data) upon load complete. I've tried XML.ignoreProcessingInstructions = false and no effect. xml.children()[0] is the first node, not the declaration. Do I need to manually parse the raw string data that is returned from URLLoader?
I'm currently working on a project where I'm having to deal with a lot of different variables and am wondering if there would be a way to cut down on my declaration ones (there are currently 152 variables dedicated to one small portion of the project.)What I have is a type, which has some subtypes(4), which have even more subtypes(subtype 1a-c: 7 types, subtype 1d: 13), which have yet another set of subtypes(which are basically subtype 1a-c's + few more, and are all applied to subtype 1d.)
View 5 RepliesActionScript Code:
mc.addEventListener(MouseEvent.CLICK,clic);
function clic(evt:MouseEvent){
var clip:MovieClip=evt.target as MovieClip;
removeChild(clip);
}
1) Why it's also possible write removeChild(DisplayObject(clip)) and for what? In which case it's necessary?
2) if I write var clip=evt.target it's works too but if I write var clip:MovieClip=evt.target it doesn't work. Why? It's a movieClip that should go in the variable var.
I'm having trouble reading an XMLDocument object that has an xml declaration. When I try to trace the first child of the document I get nothing. I've run into this before but it wasn't a problem because previously I was in control of the format of the xml, so it was no problem to just not have an xml declaration, but for this project I don't have that control.

I'm building a Flex/Flash Builder 4 application that loads data using E4X/XML, like this:I originally build an application that was a single MXML file which loaded this XML file and built a form from the data.I've now build a main menu screen with a button to load the form screen as a seperate module. How do I get the XML declaration to work in this module without loading it again.
View 1 RepliesHow do you add an XML declaration - < ?xml version="1.0" encoding="UTF-8"? > - to a Flex XML object? The same thing you could do with the old XML - new XMLDocument class and the xmlDecl property.
View 1 RepliesIn Flex you can use Declarations tags fo non UI elements.Problem:The order of classes inside the Declaration is sorted ascending or something...Meaning that in this example, AClass will be instantiated before BClass:
<fx:Declarations>
<local:AClass />
<local:BClass />
I am trying to use the global variable declaration. Up to know I've been using the x coordinate of a movie clip to pass variables between different movies, and I thought it was time to learn properly! Just to get it to work, I am trying a flash file with two movies in the root. One movie defines a glabal variable on load;
_global.numb = 6;
And then I am trying to just get the other to trace it on enter frame, so the code attached to the other movie (on enterframe) is...
trace(numb);
(And I tried trace(_global.numb) as well, but I was under the impression that you only had to define it as being a property once.). All that happens when I run the movie is nothing is traced.
Is it possible to add elements to a vector when it is declared, like you can for arrayse.g.for an array, you can just go Code:var myArray:Array = [2, 4, 1, 17, 16, 24]which will leave you with an myArray filled with those numbers in one nice, tidy single line of code .However vectors seem to complain whenever you try to add anything to them when you instantiate them.As far as I know you have to do this instead
Code:
var myVector:Vector.<int> = new Vector.<int>
myVector.push(2)

Lets say I want to call a function with an optional Object, how do I write that?If it was a String or a Number or some simple data type it would be:
Code:
function foo(s:String="Sample String", n:Number=100):void{}
But anything I try with an Object just throws an error. For example...
Code:
function foo(o:Object={x:10, b:10}):void{}
...makes the compiler barf, and so does every other version of this I've tried.
I am putting together my file right now which is now using visual elements purely added and removed via AS3 (addChild / removeChild) methods.My question is just about the proper time / place to declare their variables.Can I declare them all at the start of the movie (frame 1) and just call them when I need them, or is it better to declare them on the frames that they are introduced on? I guess the question is really, will I ever lose those variables throughout the movie once they are declared?

I am trying to access a function in a MovieClip that has been added to the stage. Right after loading in the function, I create a function that calls the function in the recently added MovieClip. The compiler does not recognize the Function and when I go into debug mode it shows up as null. I've tried declaring the function in the MovieClip using 3 different methods, but I get the same result.
Code:
function Sleep(){
var Sleep = function(){
this.Sleep = function(){
What I find strange is that when I declare the function on the stage, it looks just fine and I can even see it (as a Function object) in the debug panel.
If I do something like:
<myComponent id="foo" title="bar" />
The parameters don't seem to be available immediately within the component. When do they become available?
I'm wondering if is there any way to mimic the same behaviour we have for top level classes in AS3 for example:
