Question

Can variables be created dynamically without declaration when we write as Document class in AS3?

For example, from a library I’m importing sound files. Some 20 sound files.
If the code is in fla itself, we can assign in for loop like:

this["SOUND"+increasingNumber]

But in documentClass this is not working , since this refers the class here not the stage.

Any method to create variables?

Answer 1

When imported into your library, right click the sound file and go to its properties. Click the actionscript tab and check ‘export for actionscript’. Give it a class name which you can then use in your document class to instantiate that sound.

If you named it Sound1:

var sound:Sound = new Sound1();
sound.play();

[Edit to loxxy’s reply] above shows how to create the variables in the document class.
To dynamically create all the sound variables, I’d recommend using an array, like so:

Suppose you named all your sounds in your library Sound1 to Sound20

import flash.utils.getDefinitionByName;

var sounds:Array = [];
var soundClass:Class;
for(var i:int = 1; i<21; i++){
soundClass = getDefinitionByName("Sound" + i) as Class;
sounds.push(new soundClass());
}
