Hi guys, ok so far I have two classes in my project. A document class which sets up the Papervision3D environment (camera, scene etc) and then it creates instance of a class called “Bar”. Bar.as creates cubes using PV3D’s “materialsList”, “new Cube()” etc etc…

Now, in the document class, once I’ve finished instanciating all my bars, I try to start an onEnterFrame which rotates the bars in the scene but that’s where I’m having trouble. Here’s the document class…

```auto
package
{
    import flash.display.MovieClip;
    import flash.events.Event;
    
    import org.papervision3d.cameras.Camera3D;
    import org.papervision3d.scenes.MovieScene3D;
    
    import com.Bar;
    
    public class BarsSetup extends MovieClip 
    {
        public var container: MovieClip;
        public var scene: MovieScene3D;
        public var camera: Camera3D;
        public var bar1:Bar;
        
        public function BarsSetup() {
            setupPapervision();
            var bar1:Bar = new Bar(scene, 100);
            
            scene.renderCamera( camera );

            stage.addEventListener(Event.ENTER_FRAME, enterFrame);
        }
        
        public function setupPapervision() {
            container = new MovieClip();
            container.x = 300;
            container.y = 200;
            addChild( container );
            
            scene = new MovieScene3D( container );
            
            camera = new Camera3D();
            camera.z = -500;
            camera.zoom = 5;
        }
        
        public function enterFrame(event:Event) {
            // ***ROTATE BAR1 HERE***
            scene.renderCamera( camera );
        }
    }
}

```

And here’s the “Bars.as” class…

```auto
package {
    import flash.display.Sprite;
    
    import org.papervision3d.objects.Cube;
    import org.papervision3d.materials.WireframeMaterial;
    import org.papervision3d.materials.MaterialsList;
    
    public class Bar extends Sprite {
        public var bar:Cube;
        public var thisBar:Sprite;
        
        public function Bar(sceneBase, xPos:Number) {
            var allM:WireframeMaterial = new WireframeMaterial();
            allM.lineColor = 0x000000;
            var materialsList:MaterialsList = new MaterialsList();
            materialsList.addMaterial(allM, "all");
            
            var bar = new Cube(materialsList, 200, 200, 200);
            bar.x = xPos;
            
            sceneBase.addChild(bar);
        }
    }
}

```

Everything loads up ok with no errors in this case but what exactly do I write on the line which I’ve marked “// \*\*\* ROTATE BAR1 HERE \*\*\*”?

Really hope you guys can help! Thanks very much,  
Dave
