Hi guys,
I am trying to use the addChild method to add a MovieClip from the library onto the stage. I have a set of MovieClips with classes named: Definition1, Definition2, and so on… up to Definition12.
What I am trying to do is to write a function so that depending on the function parameter (which is a random number generated from 1 to 12), it will load different MovieClips starting with “Definition” followed by the random number. I have something like this but the syntax is incorrect. Can someone please correct me on my syntax? Thanks!!
```auto
private function attachDefinition(random:uint):void {
var _definition:MovieClip = new ["Definition" + random.toString()];
this.addChild(_definition);
}
```

look into getDefinitionByName()… in help (F1) - select AS 3.0, in the language and components reference \> All Packages \> flash.utils package \> functions.
Hope this helps.
