I want to create a function pointer object:
private var func:Object = { Class.Constant: function };
What is the clean way of doing this? I did the above and got
Error: Syntax error: expecting colon before dot.
And I'm not even sure that's right. The goal is that I can just do
func[ Constants ]();
I 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?
How 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 RepliesLets 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.
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 have a class that holds some constants and will receive an object literal (associative array) with some data like this:
var ConfigObj:Config = new Config({
"Some" : 10,
"Other" : 3,
"Another" : 5
});
The class looks like this:
public dynamic class Config
{
static public const SomeProperty:String = "Some";[code].....
I'd like to make an object that has it's properties named by constants from another class but can't quite get it to work. I'd essentially like to do something like this:
var myObject:Object = {Event.OPEN:"value", Event.COMPLETE:"value2"};
This syntax causes compiler errors.
i want to put all variables of an object into ByteArray in declaration order. the object can be a extends one. here is my code:
private static function getVariables( packet:*): Array
{
var vars:Array = new Array();

what does the "pos" for ?
i try to print the xml, but i can not find the meaning of "pos"....
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 RepliesJust wondering if there is a way to read class static constants from a SWF file server side. I have found things like getimagesize() but it doesn't have all these details. I guess that means I need a partial decompiler.Specifically, I have this class in my Flex project:
package
{
public class AppVersion
[code].......
ActionScript 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.

View 4 RepliesHow can I have a constant in a Flex application which I could apply at several places in a Flex CSS file? For example I may have a background color which is the same in several UI components and then I would like to have this color set in only one place and reused in all style clauses. Something like ...
public static const myColor = "#00FF00"...
component1 {
backgroundColor: myColor
}
component2 {
backgroundColor: myColor
}
Basically I want to call a const by a int. Here is the code I have so far...
public static const _100:String = "name=lion legs*type=legs";
public static const _101:String = "name=lion tail*type=tail";
public static const _200:String = "name=tiger legs*type=legs";
///more lines going down with the number on the far left being the main differentiating factor
public static function getByName(name:int):String {
[Code] .....
Is there a better way out there to call the constants by an outside int without having a switch function handle the logic?
I know this doesn't work, but basically, I'm looking at something like this:
robot_mc.skullplate_mc._visible = false;$skull = String(robot_mc.skullplate_mc._visible = false);
because I know I can abbreviate stuff like
yellow = Key.KeyisDown(Key.RIGHT);
blue = Key.KeyisDown(Key.UP);
green = yellow && blue;
if(green){ball_mc._x += 5; ball_mc._y -= 5;}
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 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)

i can write constants in two ways:
MouseEvent.CLICK - "click"
MouseEvent.ROLL_OVER - "rollOver"
TextFieldAutoAlign.LEFT - "left"
etc.Is there any difference between the two ways of writing?
Despite if it is good practice or not, I read here that you can have package variables (or constants), so I tried this:
[Code]...
I just found out that it is executed like a normal variable at runtime. Typically constants are supposed to be 'inlined'........ so when you write this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
...you should get this in the SWF:
ActionScript Code:
o.x += 5;
...but when I decompile my SWF I get this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
Is there a way to force the Flex compiler to inline constants in AS3?
How can I get the ord values of certain keys. Say if I want a function to run when the left arrow key is pressed or right arrow key. Or is there a constants list?

View 14 RepliesI 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?
