ActionScript 3.0 :: Variables Inside Names Again?
Dec 9, 2010
If I have a MovieClip called parent_mc and inside it I have another called child1_mc, I can use a variable for the "1" part of child1_mc and change the alpha for example like this:
ActionScript Code:
var myVar:Number = 1;
parent_mc['child'+myVar+'_mc'].alpha = 0.5;
What is the right syntax to use if child1_mc is not actually a child of anything and just sits on the stage? I have tried the following and it didn't work:
ActionScript Code:
['child'+myVar+'_mc'].alpha = 0.5;
and I tried:
ActionScript Code:
stage['child'+myVar+'_mc'].alpha = 0.5;
That didn't work either.

The thing is, I create a grid on the screen, and each of its element is given a name. The question is, how can I access those specific grid's fields by their names? Here's the code:
ActionScript Code:
private function drawGrid():void
{
var startX:uint = 0;
[Code]....
Now, If I wanted to remove, for instance, the box of the 13th row and the 25th column, how can I do that?

if i have mc duplicated or an object instance name thats stored inside a variable how can i call it? for ex: _root.mov1._x = 53; What if i want instead of mov1 a variable name. lets say randomname is a var and it holds the name of a duplicated object with a name i dont know since its random. now how can i call it just like the example above cause i tried
_root.varname._x=33; but it thought varname was an instance name instead of var.

So, I have something like..
Code:
select = ("block" + number);
trace(select._currentframe);
number++;
This is because I have 5 movieclips named block1, block2, etc. However, it returns undefined. When I directly state the instance name, like:
Code:
trace(block1._currentframe);
It works. How do I use variables as instance names?

I would like to make an Object that has key names taken from a variable. Probably this is not clear enough, so let me make an example.
I have two variables var str1:String = 'firstKey'; and str2:String = 'secondKey';
How can I make an object that would look like:
var obj:Object = {firstKey: 'some value', secondKey: 'some other value'}, note that firstKey and secondKey are values of variables str1 and str2.
Doing obj = {str1: 'some value', str2: 'some other value'} does not yield a result that I would like

I can't create new variables within a for loop:
ActionScript Code:
for(var i:int = 0; i<numBtn; i++) {
var this['menuBtn'+i] = new Sprite();
}
This doesn't work, saying I need an identifier before 'this'.
What I am trying to do is to make a dynamic menu, and the number of buttons depend on how many files there are in a directory, as each button links to each file;I get this value (numBtn in my example) from a php script, and I need to make a menu depending on it, but I can't seem to make it so that when I add a new file into that directory, a new button comes up on the menu and I don't have to change my flash file.

I have created movie clips using loops that names them box1, box2, box3.... via = i + 1;duplicateMovieClip (_root.box, "box" + i, i);but i then want to edit a textbox which is rooted inside each movie but related to the movieclip just produced. so if box1 had just been produced then:box1.textbox.text = " E cell = +j+"V";is done so effectively i am looking to do: box+i.textbox.text = " E cell = "+j+"V";

I am using the tween class to change the alpha value of a MC upon rollOver and rollOut. To refine the effect, I assigned a variable to the MC's alpha value so if the mouse moves off the MC before it has reached 100% alpha, it wont start immediatly fading from 100%, but from the value it had reached before the user stopped the rollOver action. Unfortunately, when I leave my mouse over the MC until it goes to 100%, and then I wait a second or two, the alpha snaps back to 50% (the starting alpha value).I can't figure out why this keeps happening, but I have run into it with other projects and I surmise it is the way I am using the tween class. Below is the code I used to make this happen.To see the problem, here is a link to the compiled file:
// image 1 Set 2
groupA.group2.image1.onRelease = function() {
loadMovie("main_resized/1.jpg", pictureHolder);

I've created a button in Flash, and inside that I have a TextField and a MovieClip, both with instance names set. They cover all 4 frames of the button, with no keyframes.I found I couldn't access the objects using the instance names I'd set, so I used this piece of code to see what's going on:
var obj:DisplayObject = this.m_graphics.btnChange.upState;

I have a simple FOR loop which runs through an array of MC names, which runs fine, but I'm trying to use these names inside this array as hittest values. So, I have one MC, and the code in this MC runs through an array and checks for any collisions between it and the mc in the array.

I have here a nice contact form. The only problem I got is that I would like to have the field names (name, e-mail, telephone), displayed inside the right field, (so when the user clicks inside, the text would disappear automatically) in stead of displaying the names next to the fields. My first tough was to write inside each field, in flash the field names, and it was ok for the first look. But the user needs to delete first the field names like "name" from the input box, in order to enter his own. How could I make these field names automatically dissapear when the user clicks inside a text box?
The code:
stop();send_btn.addEventListener(MouseEvent.CLICK, submit);
function submit(e:MouseEvent):void{var variables:URLVariables = new URLVariables();
variables.fromname = name_txt.text;
variables.fromtel = tel_txt.text;variables.fromemail = email_txt.text;
variables.frommessage = message_txt.text;

The question is about producing a learning package for users to improve their mathematical skills.One part of it is for times tables. So the user will enter their name and then a question will appear e.g. "What is 6 X 9?" The user then inputs their answer and the system will compare and process the input, storing the incorrect and correct responses and then giving a final score at the end.The question is to; identify the names of the likely variables and processes required for the system generation of a question and the subsequent processing of the user's response.(10 marks)Then it asks to write some pseudo-code to describe 10 consecutive question/response activities and their final results showing their name too. (15 marks)

I have an Arrays that contains the names of MovieClips:
Code:
var MyMCs:Array = ["A","B","C","D","E"];
The actual MovieClips names are "MC_A", "MC_B", etc..., I use this method so I reuse the same Array for multiple tasks, I simply add what ever it's needed to the name to match the task at hand. On this case I add "MC_".
Then I have multiple Arrays, with the same names of the values of MyMCs. The values of each these Arrays are the names of buttons that are inside the movieclips of MyMCs:
Code:
var A:Array = ["RR","TT"];
var B:Array = ["YY","UU"];
etc...
I could add a listener to a button this way:
Code:
MC_A.YY.addEventListener(MouseEvent.CLICK, DoSomething)
My problem is that i want it to be done dynamically, using the Arrays values in a loop to add Listeners to the all buttons. The loop system is not a problem for me... my real problem is in the dynamic attribution itself.
Here is what I have:
Code:
//'i' and 'j' have previously been created
for(i=0; i<MyMCs.length; i++){
for(j=0; j<this[MyMCs[i]].length; j++){
[Code]....
I know that this is correct since I tried them separately and I can trace the proper values.
I know that my problem is in the "this" since I get an error message stating:
1084: Syntax error: expecting identifier before this.
I suppose it should state something else... I tryed with "root", "parent", "child", "MovieClip"... with no luck...

We've got an Illustrator file with something over 1,000 layers. We're trying to import this into Flash and keep the layer names intact, such that they become the names of the movie clips that are imported for each layer and can be used programmatically. (It is a diagram and arrows, boxes, etc all have callout names that will eventually allow them to link to a database.)As near as I can tell, the Import dialog will NOT pass this info across between the two parts of the dialog.
