I need Help with Pong Like Game For Android

using UnityEngine;
using System.Collections;
public class MoveRacket : MonoBehaviour {
public float speed = 30;
public string axis = "Vertical";

void FixedUpdate () {
float v = Input.GetAxisRaw (axis);
GetComponent<Rigidbody2D> ().velocity = new Vector2 (0, v) * speed;
if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Moved) {
// Get movement of the finger since last frame
var touchDeltaPosition = Input.GetTouch (0).deltaPosition;
// Move object across XY plane
transform.Translate (-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);

}
}
}

That is currently my code the touch input part was just copied and pasted and it sort of works but I only want Y to change position and maybe I could have to drag it up. As of now when I click my racket just disappears .Thanks for the help in advance, I am an absolute beginner.

 

Hello. Before all, sorry for my bad english.

I'm completely new to Unity, and i have no idea of inputs on mobiles. I'm doing a pong game too, and have copied your code for inputs in mobiles. Simply i have change the speed to 0.40 and in transform.Translate i have put 0 in x parameter and it works.

I suppose that you have solucionated the problem, but maybe this can help to solutionate this, to anybody that have the same problem. (I used Unity 5).
