ActionScript 3.0 :: Generate Variable Names Dynamically To Get The X Coordinate?
Sep 28, 2010
I am trying to generate variable names dynamically to get the X coordinate for many MovieClips on my stage.
This sort of works:
stop();
var End_X_mcArm01_Dot0:Array = [];
for (var Four_counter:int=1; Four_counter<=1; Four_counter++)
{
[Code].....
It stores the X coordinate in the variable End_X_mcArm01_Dot0[Four_counter] which is great. But I want to store these values for use later in my FLA.
If you turn the comment off on the second trace it errors although it appears to have created a variable called "End_X_mcArm01_Dot01".

After some further testing, I found out that under Actionscript 3 XML (E4X) I'm unable to use dynamicaly created variable names...
The famous:
Code:
var i:number = 111
this["someVarName" + i] = "actual_value"
trace(someVarName111) // = actual_value
does not work for me with E4X lingo...
Code:
var myXML:XML
myXML = "...." //asume valid XML content here
trace(myXML.XMLData.@Memo_EN)

dynamically assign variable names from XML? For instance, if I have an XML file with a list of variable names and their respective values, can I make my Flash movie create these variables?

use a loop to create a set of variable names. The forums have figured out how to do this in AS2. This works in AS2...
PHP Code:
for(var x=0; x<3; x++) { this["var"+x] = x;}trace(var1); // 1trace(var2); // 2

i need to dynamically create arrays with variable array names.
for example, something like this:
for (var n=0 ; n < nodeContainer.length ; n++) {
nodeObj = nodeContainer[n];

I have a series of dots on a world map that depending on certain criteria move from one country to another. At the moment they move to a random point around the country's (mc) centre, as calculated by addind half the width to the x or y coordinate etc. This pressents certain problems such as the centre of the US is actually outside the boundries of the countries borders because of Alaska. Other countries such as the UK have dots floating just off the coast. The dots also cluster coveringing each other up.
Is it posible to generate a random x and y coordinate that is inside the boundries of an irregular shaped mc such as a country. I know that Flash must have these values because of colision detection and mouse overs. I just don't know how you go about accessing them.

I have been working on a Flash movie that loads variable data from an external XML file and dynamically displays the item names in a menu which may then be clicked to display other dynamically-loaded content that corresponds to the menu item that was clicked. I have now come to a standstill in the project as there is something I'd like to achieve but simply cannot work out how. This is my first attempt at working with XML in Flash and one of my early attempts at using variables. What I'm trying to achieve is; once the user has viewed the item's content, they can simply click "next" and "previous" buttons to display all of the content for the next or previous items in the XML document.
I know it probably sounds simple and I'm sure some of you could achieve this in 5 minutes (!) but I can't get my head around some of the coding. I assume previousSibling and nextSibling would come into play here as well as some sort of functions which access arrays of data for the previous and next items, but I'm just not sure how to correctly put these things to use. Rather than post my code and example images of the stage up here on the forums, I've created an html page here: [URL]

I started a thread about a reference to a symbol House, in the output window, which was: House_1. A lot of people said some useful things about that. All day I've been thinking about it, and I came to the conclusion that I don't understand things, at a very basic level.
Consider:I make a movieclip which I give the Symbol name Drawer. (I don't export it for AcitonScript.)On the stage I manually place two instances of this Symbol. The first one I give the Instance Name drawer (in the properties panel). The second one I leave nameless.Now if I trace the names of both these clips, by
trace(this.getChildAt(0).name);
trace(this.getChildAt(1).name);
the output window gives me
drawer
instance2
Now I know that the so-called "instance name" which I gave in the Properties Panel (drawer) is, in reality, a variable name which Flash gives my first instance behind the scenes. And instance2 is a name that Flash gives my second instance. What exactly the nature of that name is, I do not know.My point is: both names (drawer and instance2) are the .name property of these movieclips. Otherwise I could not have traced them through asking for the .name property, in the above. Yet only the first of these two can be manipulated:
drawer.x can be set;
instance2.x can (as we know) not be set.
But...why? What is the real difference between these two kinds of names? How can they both be the .name property of their underlying movieclip, yet be of such a different nature? What IS the nature of the instance2 name? If it's a String, how come the .name property of one movieclip can be a variable name, while the .name property of another (but identical) movieclip is a String?
I've searched every bit of web page on the net I could find. But it looks as if nobody addresses this issue. We all just work with it - but it makes no bloody sense. A name property = a name property, you'd think. Whether Flash set it or I set it should not make a difference. The x property of a clip, for example, does not change in nature according to who set it - me or Flash.So, again, just to emphasize the problem: how can a property (the name property) of a movieclip change in NATURE depending on who set it? After it's been set, shouldn't the name property of a clip be of exactly the same nature as the name property of another clip?

I'm attempting with no success to use a for loop to generate numbered instance names so that I may attach an event listener to multiple movie clips at once.Ex: I have 10 movie clips with instance name button_1 to button_10 and I'd like to be able to do something like this:
Code: Select allvar btnName:String = "button_";
for (i = 1; i < 11; i ++) {
[ btnName + i ].addEventListener(etc, etc);
}

I'm still learning flash and actionscript 3 and i am having trouble with variable and object names. I need to be able to combine variable names together (in the same way as php can combine by doing var1.var2).
My swf contains 4 loaders (image1_loader, image2_loader etc..) which are a child of (image1_content, image2_content etc.....)
I then have 4 buttons which load an image into the loader and while doing so they define the currently active loader.
Finally i have 4 control buttons - scale up/down and rotate clockwise/anticlockwise which should only control the currently active loader (as set by the buttons above)[code]...

So my buttons as well as loading the image have the event listener:
image1_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection);
image2_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection);
(and so on..)
function setCurrentSelection(e:MouseEvent):void {
[Code]...
So within the rotateClockwise and rotateAntiClockwise functions i need to be able to recognise which is the currently active loader and have that number instead of the X - so if it is image1_loader - it needs to be image1_content, if 4 - image4_content... I had tried to do it as this but it doesn't like it being a string:
rotateAroundCenter((activeLoader+'_content'), 10, ptR);

I am working on a project where the user can add items to a "board". What I need is to generate a list at the side of the "board" with the names of the products selected (there could be multiple inctances of the same product used). When I drag a product to the trash, I also need it to disappear from the list as well.

I have a script that parses some complex XML. When the XML element is of a certain type, it generates a comboBox using the XML element's children to populate the box. I then want to check all of the values of the all the generated ComboBoxes against their correct answers (which is also info stored in the XML file). When creating the ComboBoxes, I added an "id" property. However, it seems that I cannot them use:
dynamicQuestion.id.selectedItem.labelField
to check the answers. However, I am able to get the labelField if I know the variable name used to create the ComboBox.
dynamicQuestion.selectedItem.labelField
This indicates (to me) that I need to dynamically generate the variable name as I'm creating new instances of the ComboBox. But how do I dynamically generate a variable name? If I use
var thisBox:String = "box"+boxCount;
var newBox:ComboBox = thisBox as ComboBox;
I get an implicit coercion error. I also tried changing the creation statement to a function that accepted an argument, "thisBox," but this didn't work either. Conceptually, this seems quite simple, but I'm having a hard time putting it to practice. It seems that the comboBox's id is what is generated by created the box using script (e.g., var thisBox). How do I dynamically generate this name?

I'm making a game and I an in-game editor that is able to create entities on the fly (rather than hard coding them). I'm using a component-aggregation model, so my entities are nothing but a list of components.
What would be the best way to obtain or generate a list of components? I really don't want to have to manually add entries for all possible components in some giant registerAllComponents() method or something.
I was thinking maybe somehow with reflection via either the knowledge that all components inherit from the base Component class, or possibly via custom metatags but I haven't been able to find ways to get a list of all classes that derive from a class or all classes that have custom metatags.

I'm using a compination of actionscript's getPixel and php's imagecreatetruecolor and imagesetpixel to generate a png image of an swf movie inside a browser. At the moment it will output a 72 dpi image at the same resolution as the swf movie, but I've been asked about the possibility of generating a 300 dpi image instead.

The main thing that intrigues me about the project is that it can create FLV thumbnails on the fly using the VideoThumb.as file included in the project download. Unfortunately, the project was made to be used on Flash Communication Server, and I am using Progressive FLVs on my site. I have been trying to figure out how to convert the VideoThumb.as file to work with progressive FLV instead of streamed FLV. I must say that I'm quite surprised no one has done this yet, as I think it would be a valuable contribution to the Flash FLV community.Anyways, as far as the code in the VideoThumb.as file, the main part I don't understand is this snippet...ok, so it's a pretty big snippet
Code:
// str is the suggested string to render from the tree (based on the node)
// node is the entire XMLNode for the row
