ActionScript 2.0 :: Defining An Object With Variable Properties

What I need to accomplish is this:
Code:
var cnms = this.cNames.split("|");
myDP = new Array({cnms[0]:"Chris", cnms[1]:"Priceless"}, {cnms[0]:"Nigel", cnms[1]:"Cheap"});
Obviously, this doesn't work, otherwise I wouldn't be typing this right now. How do I define an object with variable properties ? I've tried eval(), but it doesn't work either.
How could I use string content to define new object in variable. Instead of[code]...
View 4 RepliesI'm making a platform game where all of my level components (ground, background etc.) are within an array called 'levelArray' so I can move all the elements the same amount at the same time. I'm just starting to implement my second level, and I need to change 'levelArray' to contain different level elements. I've tried to put an 'if' statement to change the definition of the variable:

I initialize the "point" object like:
point = {x:'209', y:'270'};
trace(point.x);
this is working fine, But I have to initialize the "point" object with a string variable which holds the initialization properties like:
[Code]...
I know this is not working. Is there any method to initialize the object with a string variable which holds the initialization properties (without parsing the text) ?
if defining variable types in function parameters gives any speed boost.
e.g
ActionScript Code:
function DoIt(param1,param2,param3):void
{

is there any performance difference between above functions. in theory compiler should be able to manage memory more efficiently when knowing what data to expect, but is it so in flash
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?
View 1 Repliesi'm linked a MovieClip class object to my project, and i will programatically add it to the display list. is there a difference between defining the variable's data type and not doing so? neither produce a runtime error.[code]

I think I am on the right track here but if someone could help that would be great. I have a piece of code that loops ON_ENTER_FRAME and it is used to check if a pistolBullet is hitting a barrel.
The problem I have is that I can check for collision of a barrel, if I manually type the name 'barrel', 'barrel2' etc within this code:

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 a task: I need to place about 100 sprites on one canvas (with prepared grid on it). I need to place them as invisible (circles) stones, on the board, and make visible only on mouseover. The problem I come across is following, I can't place those objects accurately into the nodes on the grid.

Allright, i receive a string and want to convert it to object. here a test that i have made:

this work pretty fine... but i am receiving the object property as follow: "{a:'test',b:'testAgain'}" How can i easily convert it to object properties?
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.
In my subclass, I call "super()" after setting an object's data. Whenever you set the object's data, "super()" sets it back to null. Meanwhile, if I define arrays before "super()", they do not get reset.

View 4 RepliesI do occasionally use this useful property of the flash.display.MovieClip class
for eg:
var mc:MovieClip = new MovieClip();
mc["myVariable"] = myAnotherMovieClip;
mc["myVariable2"] = true;
mc["myVariable3"] = new Array(0,0,1);
Well, I'd like to learn more about this 'feature' of movieclip. As I got to know this from a colleague and do not really know as to what this is called in AS3.
I've been working at this for hours and still no luck what I'm trying to create to have 8 buttons on one frame leading to different scene each. In the scene different things happen and then eventually it leads you back to the first scene without the pressed button there anymoreFirst I tried this:I've been try to do this for a while now and seem to be really stuckIn my movie I have 2 scenes in the first one there is a button that is flashing using tween and alpha. in this scene I'm using this code:
stop();
btn1.play();
btn1.onPress = function()

how to trace all properties of an Object regardless of data type?
View 4 RepliesI'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?

The following won't work:

Is there a way around it so an object can create it's own properties using functions?
Does anyone know how I could remove properties that have been set on a static object in AS3? it would be something like -
foreach(property in GlobalStaticVar.properties) {
GlobalStaticVar.removeProperty(property);
}
can i modify the property inside its class, and then get it from another class with the modification done on it?

View 1 RepliesI 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!!
Code:
pic[
{
clip2:{
[Code].....
i load this data from an xml and need to place the images in stage according to details given.i convert the xml to an object so its convenient.
now i need to loop through this data (properties of the pic object) and load each image and set their properties.
how to loop through the properties as there can be any number of them. here you get 3 (clips0,texts1,clips2)..
