Input in android

Hi guys
can any one here tell me what to do , i'am good with 2D in unity ,
i want to build my game to android ,the problem here is i don't have any idea about input in android ,
per example i have a spaceshotter game, and i want the spaceship move when the player hit the screen,
any help
please.

 

if you have ship with rigidbody2D

Code (CSharp):

1. public Vector2 shipPosition, touchPosition, shipDirection;
2.     void Update () {
3.         if (Input.touchCount > 0)
4.         {Touch touch = Input.GetTouch(0);
5.             if (touch.phase == TouchPhase.Began){
6.                 touchPosition = Camera.main.ScreenToWorldPoint(touch.position);
7.                 shipDirection = touchPosition - shipPosition;
8.                 rigidbody2D.velocity = new Vector2 (shipDirection.x, shipDirection.y );
9.             }
10.         }
11.     }

its not realy good example, but you can make it better for your game
