I'm getting 2 strings from XML and would like to create a variable named with the first string and with the value of the second string ... something like this :

_root.myFirstString = mySecondString;

how can i do this?

Thanks a lot for your help!

str1 = "vari";
str2 = "ables";
this[str1] = str2;
trace(this[str1]);

/* Ctrl+Alt+V to List Variables (MX)
Variable _level0.str1a = "vari"
Variable _level0.str2a = "ables"
Variable _level0.vari = "ables"
*/

str1 = "vari";
str2 = "ables";
this["a"+str1] = str2;

/*
Variable _level0.str1 = "vari"
Variable _level0.str2 = "ables"
Variable _level0.avari = "ables"
*/

actually i would likw to get something like this :
str1 = "vari";
str2 = "ables";

so

a_vari = ables


i tried your solution :
this["a_"+str1] = str2;

but it's still give me this :

vari = ables


thanks

how are you checking your returned variable ?

i have this code -

str1 = "vari";
str2 = "ables";
this["a_"+str1] = str2;

on the main timeline i have a dynamic text field
it has a variable name of - a_vari,

the textfield displays "ables" and listing the variables returns -

Variable _level0.str1 = "vari"
Variable _level0.str2 = "ables"
Variable _level0.a_vari = "ables"

Edit Text: Target="_level0.instance1"
variable = "a_vari",
text = "ables",

I'm using this in a function ... if i trace right after my declaration, everything is fine.

But my problem is that this movie is loaded from another one ... and I want to be able to play this movie alone OR from another movie (loaded in a movie clip) so I was wondering if I can declare the dynamic variable directly on _root ...

Thanks a lot for you help!

in sub.swf -
str1 = "vari";
str2 = "ables";
this["a_"+str1] = str2;

/* run alone would output
Variable _level0.str1 = "vari"
Variable _level0.str2 = "ables"
Variable _level0.a_vari = "ables"
*/

if loading sub.swf into a movieclip instance - loader that resides in the main movie,
loader.loadMovie("sub.swf");
/* this is the expected result
Movie Clip: Target="_level0.loader"
Variable _level0.loader.str1 = "vari"
Variable _level0.loader.str2 = "ables"
Variable _level0.loader.a_vari = "ables"
*/

if you load to a level,
loadMovieNum("sub.swf",1);
/* the variable in sub.swf remains on its own level
Level #0:
Variable _level0.$version
Level #1:
Variable _level1.$version
Variable _level1.str1 = "vari"
Variable _level1.str2 = "ables"
Variable _level1.a_vari = "ables"
*/

i suggest you make more use of List Variables, (Ctrl+Alt+V shortcut)
most of the answers to all kinds of problem hide there :)

Is the opposite also possible. If not, how would I do it?

example:
var = this["string"+var2+"string"];

Essentially, I need to set var to the value of a second variable. The name of
the second variable will change depending on other factors, and is being
accessed via a while loop.

totalLoops=5;
i=1;
while (i <= totalLoops){
ItemType = this["_root.Item"+i+"Type"];
if (ThisNum==count){
if (_root.ItemType=="Options2"){
gotoAndStop ("item");
}else if (_root.ItemType=="false"){
gotoAndStop ("false");
}else if (_root.ItemType=="drink"){
gotoAndStop ("drink");
}else {
Menu1.ItemName = _root.ItemName1;
Menu1.ItemDescription = _root.ItemDescription1;
Menu1.ItemPrice14 = _root.ItemPrice14One;
Menu1.ItemPrice16 = _root.ItemPrice16One;
Menu1.ItemPrice18 = _root.ItemPrice18One;
}
}
i++;
}
