I tried calling the onResize function at the beginning of my init
function and that didn't solve the problem.

looked very quickly at your code,

since class caches few values to spare calcs, try call resize(); before you do setup the class.

let me know how it goes, I will in case it doesn't fix your issue, try your class tomorrow.

also one detail, camera is standard of type Camera3D
so view.camera.x, y, z is enough, no need to declare one.

Thanks for the class Fabrice.

For some reason, when I move the mouse the sphere I'm dragging doesn't

stay under the mouse.

What do I need to do to fix this?

Thanks

Hi all,
I get many requests about this and I keep sending code...

So I've added a new class dedicated to this particular functionality.

Drag3D.  in tools.utils package

you can use it to drag an object or just to get the intersection back.

here an example of implementation

                import away3d.tools.utils.Drag3D
                [... usual away code...]
                private var drag3d:Drag3D;

                 private function setUp():void
                {
                        //the object you want to drag

var _debugPrimitive:Sphere = new Sphere ({radius:50, material:null});

                        this.scene.addChild(_debugPrimitive);

                        //declare instance
                        drag3d = new Drag3D(this.view);
                        //which plane do you want to drag on

// note here that plane != Plane primitive!!

                        drag3d.plane = "xz";

// in case you want to check what you are doing

                        //drag3d.debug = true;
                        // to assign an object to be dragged
                        drag3d.object3d = _debugPrimitive;
                }

private function myEnterFrame(event:Event = null):void

                {

//will update the object automatically on mouse moves drag3d.updateDrag(); // its is of course handy to couple this with mouseEvents, like "if mouseisdown --> drag"

// in case you want only the positionintersectback varintersect:Number3D = drag3d.getIntersect();

                        this.view.render();
                }

next to 0,0,0 default, there are also options for custom positions of plane, in case of AABB tests and even support for rotated planes

if you want object aligned calcs...

here a little tech demohttp://www.closier.nl/playground/drag/ drag3d.swf
