How do I reference the variable pointed to by the variable text?
Say I have:
engine_level = 5;
v_name = 'engine';
pb_name = v_name + '_p_button'; // so pb_name = 'engine_p_button';
level = v_name + '_level'; // so level = 'engine_level';
[Code]......
How do I reference the variable pointed to by the variable text but pointed to by more than one function?Say I have:
engine_level = 5;
tank_level = 3;
v_name = 'engine';

I want to be able to reference the text of a text box within an MCThe MC is called "box1", the text field is called "field1"...I have many MCs (all with field1 in them)... box1, box2, box3 etc etcObviously I can set the text to being something by saying...box1.field1.text = "set_this_text"However, I'm using a variable to come up with the "box1" bit. (Using an array and a loop to figure out which box I want to update based on where the user clicked). So, let's say I have a variable... and I want to say..boxClickedon = box1 //will be defined by userSo I don't know in advance about box1... I can only access it through "boxClickedin" variable, but
boxClickedin.field1.text = "set_this_text"
or
[boxClickedin].field1.text = "set_this_text"
[code]....
Lets say I have 3 Movie Clip Symbols in my Library : Movie0, Movie1 and Movie2
Each movie has a dynamic text box: "TextBox1"
I want to be able to write a function that can manipulate the alpha(or any attribute) of the TextBox1 in all three MovieClips.
In my limited experience I thought I could do something like the following:
for (var row:int = 0; row < dataArray.length; row++)
{
Movie(row).TextBox1.alpha = 1;
}
I hoped that this would loop through 3 times and set the alpha of the TextBox1 in all three movies to 1.
Is this possible? Can you reference an instance with use of a variable?
I have 10 text fields named "text1", "text2" etc;
I'd like to use a for loop to pulate each one, so that each text filed is populated with whatever i is:
for (var i:Number=1; i<=10;i++) {
"team"+i.text = i;
}
I keep getting errors with regards to how the text filed name is referenced.
What is the correct way to increment the text filed name and reference it?
I've tried:
["team"+i].text = i;
"team"[i].text = i;
but they don't work.
i want to use a variable(text) to refrence a movieclips instance name
Code:
function InventoryShow(event:Event):void
{
var SC:URLVariables = new URLVariables(event.target.data);
[Code].....
So i have an external text file organized like this:
/* $file: data.txt */
&title0=Sacrum
&detail0=Detail text for Sacrum
&title1=L5
[Code].....
There are 28 of these 'title' and 'detail' pairs. The 'title' text is to fill a dynamic text box and the 'detail' to fill another dynamic text box depending on which section the user is mousing over.
My issue is getting the text from the file stored into arrays. For my test loop I keep getting undefined as the stored value, and i know it has something to do with converting a string value to object..
var lv:LoadVars = new LoadVars();
lv.onLoad = handleDataLoad;
lv.load('data.txt');
function handleDataLoad (success:Boolean) {

I want to load an external variable called name from a text file into a local variable in flash called my_str...here's what I have:
var loadText = new loadVars();
loadText.onLoad = function(success) {
if (success) {
[Code]....
I need to have the variable my_str available outside the function..
I'm trying to make something that will show up in a dynac text field something like this:"[variable1] text text text [varibale2] text text text"I've linked the dynamic text field to a variable "resu" and set it to:var resu = variable1 + "text text text text" + variable2 + "text text text"The only problem is that when I make the variables random, they don't change
View 1 Repliesf you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".
Is there a way to reference a function via a variable? In other words, instead of saying something like:
var theVar = someString + 'function';
if (theVar == 'functionName') functionName ();
to access it directly:
(someString + 'function') ();
using some kind of bracket notation?
Using AS2. I have a variable defined:
activenav = "services";
I then want to reference the variable in a MC string. I've tried many variations of this:
_root.my[activenav]Clip.gotoAndPlay("Out");
Essentially, I want Flash to see this as:
_root.myservicesClip.gotoAndPlay("Out");
Getting syntax error.
i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.

Is it possible to reference an object using a variable value?
For example, I have a function that is supposed to hide an image and add that image to an inventory list when the item is clicked.
All the image info is stored in an object (name, imgSource, visible, x, y);
I was thinking I could do something like this:
<fx:Script>
<![CDATA[
public var item:Object = new Object();
[Code].....
I want "item" to stand for knife so that I could change knife.visible, knife.xPos, ect.
Code:
public function Text1Down(e: MouseEvent): void{
var textArea:Label=Label(e.currentTarget.id);
.......
}
I get this error:
Code:
TypeError: Error #1034: Type Coercion failed: cannot convert "text1Area" to mx.controls.Label.
I know that e.currentTarget.id is of type Label. All I want is to make a reference variable so I don't have to keep typing long names.
I'm writing a function which can take the names of different variables and use them to do some calculations. Long story short, I want to be able to call the function like this:
It probably seems like a really roundabout way to pass the variable through its name rather than just passing the variable itself. This is related to me using XML to get the variable names, so they come in as strings. Just bear with me here.
Inside the function, I want to be able to do something like this:
which should then trace the variable's value. Unfortunately, I just get an 'undefined'. How do I use 'this[]' to get the value of the variable from a string corresponding to the variable's name?

well at least in C++ it's called passing a variable by reference.
Is there, uh, a way to use the value of a string to reference a variable name?
