ActionScript 2.0 :: Get A List Of All The Properties Of The Object?
Dec 12, 2002
I am having a hard time understanding for...in loops. I have seen David use it in his signature, and I understand what the loops is doing, but only from the context of the rest of the signature. If somebody could explain how the for..in loop works, I'd be greatful. Here's what I know:
PHP Code:
for (proprtyThing in objectThing) {
trace (proprtyThing);
}
My understanding of this loop tells me that if I run it, I'll get a list of all the properties of the object named objectThing....but this makes no sense to me!!

i'm attempting to cast an object's property as an actual property of another object. here's my object variable: var propObj:Object = {prop:"width", width:50}; now i want to assign the property of a sprite using that object's properties. var sp:Sprite = new Sprite(); sp.(propObj.prop as Sprite.property) = propObj.width; now, i'm not even going to try that because i know the compiler will explode all up in my face. but you should be able to see what i'm trying to do. why i'm trying to do it is because i'm reading in an XML file with an undetermined list of usable properties for specific objects. so instead of writing something like a huge switch statement to evaluate whether the XML file has a value for that specific property, i'm trying to assign properties dynamically based on what's available in the XML file. if what i'm trying to do is possible, what's the best way to do it?

I forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project.

I have the following problem in AS3. I have a string like this one: "prop1:val1,prop2:val2,..."; I want to split and parse the string to obtain a dynamic object like this one: {prop1:"val1", prop2:"val2"}.
The simple way to solve it is to cycle through the string values and to do[code]...
Since I know the property names I expect, this works for me, but doesn't seem to be an elegant solution. I'm wondering if there is another way in as3 (similar to the reflection api in java).

I am working on an enterprise application and creating a base class for some stage components that has knowledge of the class extending it. More specifically, I need a way to loop through the inspectable properties in a class file and place the names of these variables into an array. For example:
Code:
[Inspectable(name="My First Variable", type="String", defaultValue="")]
private var _myVar1:String;
[Inspectable(name="My Second Variable", type="String", defaultValue="")]
private var _myVar2;

I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).

Does anybody know of a website that gives a full list of all as3/cs4 methods, properties, keywords, classes, etc?
I bought a book on beginning AS3, but it only introduces some properties and methods as it uses them in examples.

I'm basically loading an XML file to assign instances of a movie clip a distinct value, which it uses to modify its height. So, I'm looping through the xml and instantiating my class Object each time (Rect) and then placing that Object into an array:
Code:
function loadXML(loaded){
if(loaded){
var boxArray:Array;
xmlNode = this.firstChild;
[code]....
the trace here always comes up undefined. "listPosition" in this bit is an Rect parameter, defined in the previous bit of code as "i", so I can keep track of the order of the stack.I've found one or two examples of putting objects into an array and getting them back out, but it doesn't seem to work with this, maybe because I'm using a class. I don't know.Could this be an area where I need to use the array access brackets, like around the movie clip the object is loaded into. I've tried everything I can think of -- referencing back to the movieclip, adding extra objectRef type parameters... nothing has worked yet.

I'm doing some work with JSON in as3 using as3corelib (very useful) and was wondering if it is possible to get an object if all you have is one of its properties, also an object. Here's an example of some JSON:
"parentObject": {
"propertyObject": {
etc.
}
}
so what i'm asking is, if I have propertyObject, can I access parentObject somehow?

Back in the day (AS2), I used to create what I called an"ivar" property that collected the index of a series of buttonsthat were clickable (see attached code). Imagine 10 buttons on thestage with names (selectButton0, selectButton1, ...selectButton9).The code under the //----------BUTTONS header would make a propertyof the button that was clicked, call it "ivar" and then send it upto a function that would use it as an index to then load theappropriate content with MovieClipLoader (remember that Class?).I have tried something similar in AS3 without any luck sincethe whole button thing is now steered by events. Does anybody knowan elegant solution that would achieve a similar result. That is,click a button called "selectButton0" and have returned the zero asan index variable that could be used further?

I'm working on a project that has to pass variables to (and later read them from) a URL encoded text file.
Code:
getURL("process.cgi", "", "POST");
This has worked until now, dumping all of _level0's variables into the document, retrieving the relevant ones on load.I've recently made some modifications so that I'm no longer storing all the variables in _level0, but some of them as custom properties of objects, e.g.:
Code:
t1c1r1.customproperty = 6;
t1c2r1.customproperty = 5;
In these cases, the properties are not being passed to the process.cgi, and not getting recorded in the text file.
I suppose I could flatten the variables out, record them on _level0,
Code:
t1c1r1_customproperty = 6;
but I'm wondering if there's a way to send these variables as is.

For the first stage, I was able to build a walk-through demo in flash pro by creating buttons that when clicked caused the flash to change to different frames. easy enough. Now for the final part of this project, I need to make the interface fully interactive, as I was trying before. ie: you can click any button and lights go on and off or a loop counter increments, etc. Since there is logic involved and too many permutations to do a frame for each possible state, I'm back to trying to do this in an object oriented way. I've got some test code here.

debugger has some errors, so i don't know what exactly it will do. the errors are at the last two if statements where i'm trying to change the object property setting of the label. there is another error at the last curly bracket.
the idea is that there are two labels and a button. the first label starts out visible. when the button is clicked, a counter is checked, and incremented, then the counter is again checked and the appropriate label has it's visible property set to true. the intent is that in a list of several labels, pressing the button scrolls down them, until you press while on the last, which resets the counter and the first label becomes the visible one.

I want to set it up so the size properies will pass over to the block (same object size - height and scale) but also changing the collision properies so the player will be enable push the block around the screen but I'm not sure how to implement such functionality/feature. I've experimented with two ways so far; 1.) The enemy changes to a frame of a block when he dies (illusion of a different object but the same object with a different frame on the timeline) using the same size properies but I can't seem to the change the collision properies from it's prior setting of causing damage and re-bound/bounce to the player. 2.) The enemy is removed completely from the game and a new block object is added in the same position where enemy died but I can't share/code the same size properies to this new block object making obvious that is a different object. Here is a code I've what I've done so far (which is attempting to do first approach);

I have an engine I created a while back that loads objects into a container based on XML data. A really quick example of the XML would be like this:
<level>
<object cname="enemies.Robot">
<pos x="200" y="400" layer="mobiles" />
</object><object cname="Player">
<pos x="12" y="89" layer="mobiles" />
</object></level>
I have a class Environment that has a method loadLevel(data:XML) which I parse the XML through, then the function runs through the XML finding all object nodes and uses getDefinitionByName to determine which Object I want to create based on object.@cname. From here, I have to manually define each property based on the XML like so:
obj.x = xml.pos.@x;
obj.y = xml.pos.@y;
etc.
I was wondering if there's an inbuilt method for setting a property based on a String. By this I mean something like so:
var mc:MovieClip = new MovieClip();
mc.someInbuiltFunctionThatSetsAProperty("alpha", 0.5);
This way I could change my XML to be more like so:
<object cname="Player">
<props>
<x>200</x>
<y>221</y>
<alpha>7834</alpha>
<health>Something</health>
<power>3</power>
</props></object>
And iterate through all the children of props to set all of my properties on the fly. I know if I create an Object and set properties within it like so:
var obj:Object = {
var1: "hello",
var2: "there",
name: "marty"
};
That you can then iterate through names/values using the for(String in Object) loop like this:
var i:String;
for(i in obj){
trace(i + ": " + obj[i]);
}
/**
* Output:
* var1: hello
* var2: there
* name: marty
*/
Surely there's a way, as here's an example of identifying a property using a String:
var ar:Array = [new MovieClip(), new MovieClip()];
ar.sortOn("alpha", Array.ASCENDING);
So just to make my question more to-the-point: I want to be able to get and set properties that I can identify using a String.

I'm doing some Actionscript work right now and I'd like to know whether there's a way to initiate an empty object's value programatically like this:
var myObj:Object = new Object;
myObj.add("aKey","aValue");
To add a property called aKey whose value is aValue.I need to create a "Dumb" (data-only) object to use as a parameter to send via POST. So I don't know offhand how long and/or how many attributes it's gonna have.
