android and unity.

I recently finished the space shooter project in unity3d website and the games runs on the web brower bit when i build the android version and installed the apk the game launched and ran, i just cant control the space ship. Is there any complete tutorial for using unity to male an android game?

sure, here is the player controller script,for some reason the shooting works whenever i tough the screen but i cant move.

this is a little more organized for better reading, i used C#

using UnityEngine;
using System.Collections;

public class Boundary
public float xMin, xMax, zMin, zMax;

public class PlayerController : MonoBehaviour
public float speed;
public float tilt;
public Boundary boundary;

void FixedUpdate ()
    float moveHorizontal = Input.GetAxis ("Horizontal");
    float moveVertical = Input.GetAxis ("Vertical");

    Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
    rigidbody.velocity = movement * speed;

    rigidbody.position = new Vector3 
        Mathf.Clamp (rigidbody.position.x, boundary.xMin, boundary.xMax), 
        Mathf.Clamp (rigidbody.position.z, boundary.zMin, boundary.zMax)

    rigidbody.rotation = Quaternion.Euler (0.0f, 0.0f, rigidbody.velocity.x * -tilt);
