transform.position.z is changing position.x..

I’m writing a basic camera controller. My general approach was to set the camera as a child of a target so that I could work in local space around the target. This is what I have so far.

#pragma strict

var offset : Vector3 = Vector3(0, 2, -3);
var target : GameObject;
var zoomRate : float = 1.0;

function LateUpdate ()
{
	if (transform.parent == null)
	{
		AcquireTarget(target, offset); //Calls function to set camera as child of target object
	}
	if (Input.GetAxis("Mouse ScrollWheel") > 0)
	{
		transform.position.z -= zoomRate;
	}
	if (Input.GetAxis("Mouse ScrollWheel") < 0)
	{
		transform.position.z += zoomRate;
	}
}

function AcquireTarget(functionTarget : GameObject, functionOffset : Vector3)
{
	transform.parent = functionTarget.transform; //Sets camera as parent of target
	transform.position = target.transform.position + functionOffset; // Puts camera behind target
}

My problem is that when use mouse scroll, both the position.z and the position.x of the camera transform are changing because the camera is not moving on the x-axis in world space. The whole point of setting parenting was to work in local space… so why is changing the transform moving in world space when its a child…
