well Im trying to use IK and hitTestObject, but cant get it working. any help appreciated, here is the code:

```auto
package {
    import flash.display.Sprite;
    import fl.ik.*
    import flash.events.Event;

    public class Main extends Sprite {
        var tree:IKArmature = IKManager.getArmatureByName("Armature_2")
        var treeZ:IKArmature = IKManager.getArmatureByName("Armature_4")
        public function Main():void {
            addEventListener(Event.ENTER_FRAME, hitTO);
        }

        public function hitTO(e:Event):void {
            if (tree.hitTestObject(treeZ)) {
                trace("hit");
            } else {
                trace("noHit");
            }
