Convert Input Mouse in Input touch and test Unity

Hi guys,

I have problem in convert Input Mouse to Input Touch before testing on Unity. My code to the gameObject Plataforma to move with mouse in axis x right and left:

using UnityEngine; using System.Collections;

public class Plataforma : MonoBehaviour {

 public float velocidadeDeMovimento;
 public float limiteEmX;

 // Use this for initialization
 void Start () 
 {
     limiteEmX = Camera.main.ScreenToWorldPoint(new Vector3(Screen.width, 0, 0)).x - GetComponent<SpriteRenderer>().bounds.extents.x;
 }
 
 // Update is called once per frame
 void Update () 
 {
     float direçãoHorizontalDoMouse = Input.GetAxis ("Mouse X"); // -1 = esquerdo; 0 = parado; 1 = direita
     GetComponent<Transform>().position += Vector3.right * direçãoHorizontalDoMouse * velocidadeDeMovimento * Time.deltaTime;
     float xAtual = transform.position.x;
     xAtual = Mathf.Clamp (xAtual, -limiteEmX, limiteEmX);
     transform.position = new Vector3 (xAtual, transform.position.y, transform.position.z);
 }

}

I need to do the gameObject Plataforma respond in touch, but when touch with finger on the Plataforma it need to move to right and left axis X only. And still, I need to test the preview in Unity, to know How will the game to respond on mobile. Sorry my English.

I thank the attention!!!

Regards,

Maicon.
