Tested and Works

CSharp

<code>

private float ZoomAmount = 0; //With Positive and negative values
private float MaxToClamp = 10;
private float ROTSpeed = 10;

void Update(){

ZoomAmount += Input.GetAxis(“Mouse ScrollWheel”);
ZoomAmount = Mathf.Clamp(ZoomAmount, -MaxToClamp, MaxToClamp);
var translate = Mathf.Min(Mathf.Abs(Input.GetAxis(“Mouse ScrollWheel”)), MaxToClamp – Mathf.Abs(ZoomAmount));
gameObject.transform.Translate(0,0,translate * ROTSpeed * Mathf.Sign(Input.GetAxis(“Mouse ScrollWheel”)));

}

</code>

Javascript

<code>

var ZoomAmount : float = 0; //With Positive and negative values

var MaxToClamp : float = 10;

var ROTSpeed : float = 10;

function Update() {

ZoomAmount += Input.GetAxis(“Mouse ScrollWheel”);

ZoomAmount = Mathf.Clamp(ZoomAmount, –MaxToClamp, MaxToClamp);

var translate = Mathf.Min(Mathf.Abs(Input.GetAxis(“Mouse ScrollWheel”)), MaxToClamp – Mathf.Abs(ZoomAmount));

gameObject.transform.Translate(0,0,translate * ROTSpeed * Mathf.Sign(Input.GetAxis(“Mouse ScrollWheel”)));

}
