crosshair moves away

i am trying to handle with a crosshair, currently as a 3DText
one of my problems are the increasing distance by moving it.
An other, the placement on the correct position

//				##Controling guns##

var cross:Transform;

private var crossDistance = 10;
private var crossHeigh = 10;
private var crossPosition:Vector3;
private var sensitivity = 5;

function Start () {
	Screen.showCursor = false;
	//place cross 
	cross.position = transform.position;
	crossPosition = cross.position;

//control cross with mouse
function Update () {
	cross.Translate(Input.GetAxis("Mouse X") * sensitivity*-1,Input.GetAxis("Mouse Y") * sensitivity,0);

You should not move the GUIText’s transform position, you should only affect the GUIText’s pixeloffset in order to moving your cross hair in the screen.

Example Script C#

using UnityEngine;
using System.Collections;

public class TestCursor : MonoBehaviour {
	private Vector2 half, pos;
	void Start () {
		Screen.showCursor = false;
		guiText.anchor = TextAnchor.MiddleCenter;
		half = new Vector2( Screen.width/2, Screen.height/2 );
		pos =;
	void Update () {
		pos.x = Input.mousePosition.x - half.x;
		pos.y = Input.mousePosition.y - half.y;
		guiText.pixelOffset = pos;

If you work with GUITexture, you need to do a few more calculations to include the offset of the image itself, this is because GUITexture uses PixelInset in oppose to the PixelOffset used by the GUIText

why are you using 3d text instead 2d texture?

2d texture is the easiest way to achieve a crosshair
just draw the texture with OnGUI function
