смешно кидать саунды на таймлайн.

А ещё смешно кидать великоразумные комментарии не сказав по теме ни слова

При попытке запустить получаю:

1067: Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObject.

Ругается на this.addChild(ProjectionDragger);


Есть однокадровый FLA menu3d_pyramid.fla. В кадре такой код:

import ProjectionDragger;
 
 
var MyPr:ProjectionDragger = new ProjectionDragger();
 
this.addChild(ProjectionDragger);

Код ProjectionDragger.as:

package { 
    import flash.display.Sprite; 
    import flash.display.Shape; 
    import flash.geom.Point; 
    import flash.events.*; 
    public class ProjectionDragger extends Sprite 
    { 
        private var center : Sprite; 
        private var boxPanel:Shape; 
        private var inDrag:Boolean = false; 
 
         public function ProjectionDragger():void 
        { 
            createBoxes(); 
            createCenter(); 
        }  
         public function createCenter():void 
         {   
              var centerRadius:int = 20; 
 
              center = new Sprite(); 
 
              // circle 
              center.graphics.lineStyle(1, 0x000099); 
              center.graphics.beginFill(0xCCCCCC, 0.5); 
              center.graphics.drawCircle(0, 0, centerRadius); 
              center.graphics.endFill(); 
              // cross hairs 
              center.graphics.moveTo(0, centerRadius); 
              center.graphics.lineTo(0, -centerRadius); 
              center.graphics.moveTo(centerRadius, 0); 
              center.graphics.lineTo(-centerRadius, 0);

this.addChild(MyPr);

Теперь ругается

TypeError: Error #1009: Cannot access a property or method of a null object reference.
	at ProjectionDragger/createCenter()
	at ProjectionDragger()
	at menu3d_pyramid_fla::MainTimeline/frame1()

на строку в ProjectionDragger.as:

 root.transform.perspectiveProjection.projectionCenter = new Point(center.x, center.y);
