Android touch and go,zoom,rotation

public float speed = 0.1f; Vector3 position; bool go; void Update() {

my Cube has this script, when i touch the plane(with name "land") cube must be go in touch position, because he teleport there.

using UnityEngine; using System.Collections;

this code zoom camera succesfuly? how i can update it that he also rotate camera (onle x and y)
