Array of Class Names AS3

Question

I've got several movieclips in my FLA library with classnames applied. In my AS package file, I've got an array of those classnames. What I'd like to do is display the movieclips on stage as follows:

Upon SWF load, Array[0] displays
When NEXT button is clicked, add 1 to array, then display
When PREV button is clicked, subtract 1 from array, then display

Total n00b question, I'm sure. I understand the basics, but calling the classnames has me confused. Any help would be appreciated!

If you have an array of class names, you'll first have to retrieve the class definition before you can dynamically instantiate it. You can use the getDefinitionByName() method for that.

var clazz:Class = getDefinitionByName(myClassName) as Class;
var instance:MovieClip = new clazz();

Good catch, I didn't notice that the OP said array of class **names**. This is a more accurate answer. – Sunil D. Feb 01 '13 at 17:24

If you have an array of classes, you can instantiate a class like this:

var classArray:Array = [ Class1, Class2, Class3 ];
// instantiate the first class in the array at index 0
var instance:MovieClip = new classArray[0]();
