I'll have to give that a try on my next project. Much easier than setting up a bunch of case statements. Thanks latho! Awesome. I’ll have to give that a try on my next project.

MY_IMAGE_ID:String = “image_class_libname”

reflection looks like this:

public static function getLibClassInstance(libClassId:String):Class {
var libClass : Class = getDefinitionByName(libClassId) as Class;
return new libClass ();
}

usage:

var clazz:Class = MyLib.getLibClassInstance(MyLib.MY_IMAGE_ID);
addChild(Sprite(clazz))

by the way this is example code, untested
