onMouseDrag scroll

Hello all I want to scroll an object (in 3D space) only on the Y axis (up and down.

It's a Game object with a lot of pictures set as textures on planes. I want you to come across them in space and be able to Scroll the whole thing up & Down.

alt text

I dont want to have it as a GUI, so I was thinking of creating an onMouseDrag

     #pragma strict
 
     var cam : Camera;
     var myScroll : GameObject;
     var scrollDrag : boolean;
      
       
     function OnMouseDown()
     {
         scrollDrag = true;
     }
      
     function OnMouseUp()
     {
         scrollDrag = false;
     }
      
     function OnMouseDrag()
     {
         if (scrollDrag == true)
         {
         screenPosition.y += Input.GetAxis("Mouse Y");
         myScroll.transform.position = cam.ScreenToWorldPoint(screenPosition);
         }
     }

Although I'd like it to have momentum when you lift mouseUp I have cobbled this together but I need Help Please Thanks in advance ~be

Here is another pass if it helps inspire

(although it's a C# script)

 using UnityEngine;
 using System.Collections;
 
 public class drag : $$anonymous$$onoBehaviour {
 
 private Vector3 last$$anonymous$$ousePosition;
 
 void On$$anonymous$$ouseDown() {
     last$$anonymous$$ousePosition = Input.mousePosition;
 }
 
 
 void On$$anonymous$$ouseDrag() {
     Vector3 distance = Input.mousePosition - last$$anonymous$$ousePosition;
     Debug.Log("The mouse moved " + distance.magnitude + " pixels");
 
     // $$anonymous$$ove to last $$anonymous$$ouse Pos
     Input.mousePosition = transform.Translate.position;
 }
 
 }

But here, I gather I also have to convert world Space

ScreenToWorldPoint(screenPoint)

Thank you !
