Question

I made a function that would add a child from my library using a variable made from an xml.

var ChosenGraphic:String = units.unit.(@titel==k1).graphic;
var mc:MovieClip = new ChosenGraphic;
addChild(mc);

I know I can’t use :String for this, but I don’t have a clue what to use. I’m trying to get it to work for 2 hours now, and it’s getting really frustrating.
Everything else works, I’ve tested that.

You want to use the getDefinitionByName() top level function.

Below is an example of using it, lifted straight from the documentation that I linked to. Note that the class name string must be the fully qualified class name (ie: it includes the package name as well as the class).

package {
    import flash.display.DisplayObject;
    import flash.display.Sprite;
    import flash.utils.getDefinitionByName;

    public class GetDefinitionByNameExample extends Sprite {
        private var bgColor:uint = 0xFFCC00;
        private var size:uint = 80;

        public function GetDefinitionByNameExample() {
            var ClassReference:Class = getDefinitionByName("flash.display.Sprite") as Class;
            var instance:Object = new ClassReference();
            instance.graphics.beginFill(bgColor);
            instance.graphics.drawRect(0, 0, size, size);
            instance.graphics.endFill();
            addChild(DisplayObject(instance));
        }
    }
}
