Javascript Problem

[supamario00]

I can't seem to figure out a script that would allow me to, using the scroll wheel, move a rigidbody back and forth through its relative z axis (3D project so x,y,z).

The way it's set up in Unity is that you hold the left mouse button to pick up the item and it will move with you, what I need to do is to be able to push the rigidbody back and forth using the scroll wheel.

If anyone can figure this out I would be super appreciative as this has been confusing me for the last week.

We need some code to help you out, silly

post the whole drag rigidbody script?

[supamario00]

var spring = 50.0;
var damper = 5.0;
var drag = 10.0;
var angularDrag = 5.0;
var distance = 0.2;
var attachToCenterOfMass = false;

private var springJoint : SpringJoint;

function Update ()
{
// Make sure the user pressed the mouse down
if (!Input.GetMouseButtonDown (0))
return;

var mainCamera = FindCamera();

// We need to actually hit an object
var hit : RaycastHit;
if (!Physics.Raycast(mainCamera.ScreenPointToRay(Inpu t.mousePosition), hit, 100))
return;
// We need to hit a rigidbody that is not kinematic
if (!hit.rigidbody || hit.rigidbody.isKinematic)
return;

if (!springJoint)
{
var go = new GameObject("Rigidbody dragger");
var body : Rigidbody = go.AddComponent ("Rigidbody") as Rigidbody;
springJoint = go.AddComponent ("SpringJoint");
body.isKinematic = true;
}

springJoint.transform.position = hit.point;
if (attachToCenterOfMass)
{
var anchor = transform.TransformDirection(hit.rigidbody.centerO fMass) + hit.rigidbody.transform.position;
anchor = springJoint.transform.InverseTransformPoint(anchor );
springJoint.anchor = anchor;
}

else
{
springJoint.anchor = Vector3.zero;
}


springJoint.spring = spring;
springJoint.damper = damper;
springJoint.maxDistance = distance;
springJoint.connectedBody = hit.rigidbody;

StartCoroutine ("DragObject", hit.distance);
}

function DragObject (distance : float)
{
var oldDrag = springJoint.connectedBody.drag;
var oldAngularDrag = springJoint.connectedBody.angularDrag;
springJoint.connectedBody.drag = drag;
springJoint.connectedBody.angularDrag = angularDrag;
var mainCamera = FindCamera();
while (Input.GetMouseButton (0))
{
var ray = mainCamera.ScreenPointToRay (Input.mousePosition);
springJoint.transform.position = ray.GetPoint(distance);
yield;
}
if (springJoint.connectedBody)
{
springJoint.connectedBody.drag = oldDrag;
springJoint.connectedBody.angularDrag = oldAngularDrag;
springJoint.connectedBody = null;
}

}

function FindCamera ()
{
if (camera)
return camera;
else
return Camera.main;
}

have a look at this, this looks promising:
Mouse wheel programming in JavaScript

the only problem is that that is the name for mouse wheel in browser but I need it for a non browser program

what I was using was Input.GetAxis ("Mouse Scrollwheel") because that is what it is defined as in unity but I can't figure out how to get it to translate a picked up rigidbody along it's z axis
