unity3d move by touching

Question

I'm going to create Android app where I move gameObject on X and Z cords by touching,gameObject have to move right, left, up or down. I have written this script which belongs to gameObject where I check the touching by Raycast.

Do you know of any another method to move Object by touching ?

#pragma strict

var hit = new RaycastHit(); 

function Start () {
}   

function FixedUpdate () {

for (var i :int = 0; i < Input.touchCount; ++i) {

    if (Input.GetTouch(0).phase == TouchPhase.Moved ) {

        var touchDeltaPosition:Vector2 = Input.GetTouch(i).deltaPosition; 
        var touch_pos : Vector3 = new Vector3(Input.GetTouch(i).position.x, Input.GetTouch(i).position.y , 0);
        var ray : Ray = Camera.main.ScreenPointToRay (touch_pos);


        Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);

        if (Physics.Raycast (ray, hit)) 
        {
            Debug.Log(hit.transform.tag);

            if(hit.transform.tag == "Cubes")
            {
                if(Mathf.Abs(Input.GetTouch(i).deltaPosition.x) > Mathf.Abs(Input.GetTouch(i).deltaPosition.y))
                {
                    if(Input.GetTouch(i).deltaPosition.x > 0)
                    {
                        transform.Translate(0,0,1);
                        // 'right';
                    }
                    else
                    {
                        transform.Translate(0,0,-1);
                        //GUItest.text = 'left';
                    }
                }
                else
                {
                    if(Input.GetTouch(i).deltaPosition.y > 0)
                    {
                        transform.Translate(-1,0,0);
                        // 'up';
                    }
                    else
                    {
                        transform.Translate(1,0,0);
                        // 'dawn';
                    }
                }
            }

        } 
    }
} 

}

Answer 1

take touch position store it and compare with current touch position calculate delta and move the object

    if(Input.GetMouseButtonDown(0))
    {
        //print ("up...");
        mousePositionXYZ.y= Input.mousePosition.y;
        doit=true;


    }
    if(doit)
    {

    listGO=GameObject.Find("Main Camera");
        if(Input.mousePosition.y > mousePositionXYZ.y )
        {

        listGO.transform.position.z -=Input.mousePosition.y *Time.deltaTime *0.010;
         print ("up...");
        }
        else if(Input.mousePosition.y < mousePositionXYZ.y )
        {

        listGO.transform.position.z +=Input.mousePosition.y *Time.deltaTime*0.010;
         print ("down...");
        }   
    }   

    if(Input.GetMouseButtonUp(0))
    {
        mousePositionXYZ.y= Input.mousePosition.y;



        doit=false;
    }
