Multiple Variables in a for statement

[thekillerbigmac]

Hello,

I'm trying to declare a few variables in a for statement using the variable in the for statement. In older flash versions I would use something like this.

for(a=0;a<10;a++) {
     _root["variable"+a] = "Some text "+a;
}

But now I can't get it to work in AS3. I've tried doing different variations of...

for(var a:int=0;a<10;a++) {
     var ["variable"+a]:String = "Some text "+a;
}

But no luck.

If anyone knows an alternate way to declare variables and use a different variable to help name it, please help me!

Thanks in advance!

Two part answer. First part: You don't really want to do this. Instead, you probably want to use an Array or Vector.

var texts:Array = [];
for (var a:int = 0; a < 10; a++){
  texts.push("Some text "+a);
}

trace(texts[2]); //Some text 2

Vector:

var texts:Vector.<String> = new Vector.<String>();
for (var a:int = 0; a < 10; a++){
  texts.push("Some text "+a);
}

trace(texts[2]); //Some text 2

Second part: If you really want to declare properties on the root at runtime, you can do so if the root is a MovieClip or other Dynamic class. These are properties, not variables, and must always be accessed relative to the root rather than with just the name.

var rootmc:MovieClip = MovieClip(root);
for(var a:int=0;a<10;a++) {
     rootmc['variable'+a] = "Some text "+a;
}

trace(rootmc['variable2']); //Some text 2

Seriously, don't do that.

Thanks!

That help a bit, but I have another question for you.

I shouldve been a little more descriptive as to what I was going to get at.

Is there an easier way to create consecutive numbered TextFields without doing in that method?

I did change some other variables to arrays instead of the other way, but not sure if I'd be able to do the same thing with text fields.

Thanks again!

You can do the same Array thing with TextFields. In fact, you can do the root[name] thing with them too. They're not special.

var texts:Array = [];
for (var a:int = 0; a < 10; a++){
  var atext:TextField = new TextField();
  aText.text = "Some text "+a;
  aText.y = a*10; //just so they're not in the same place on stage.
  addChild(aText);
  texts.push(aText);
}
