Hello, i am trying to make this script work with touch controls. Any idea how to do that?

Script:

 void Update () 
 {
     if (Input.GetMouseButtonDown(0))
     {
         f_difX = 0.0f;
     }
     else if (Input.GetMouseButton(0))
     {
         f_difX = Mathf.Abs(f_lastX - Input.GetAxis ("Mouse X"));

         if (f_lastX < Input.GetAxis ("Mouse X"))
         {
             i_direction = -1;
             transform.Rotate(Vector3.up, -f_difX);
         }

         if (f_lastX > Input.GetAxis ("Mouse X"))
         {
             i_direction = 1;
             transform.Rotate(Vector3.up, f_difX);
         }

         f_lastX = -Input.GetAxis ("Mouse X");
     }
     else 
     {
         if (f_difX > 0.5f) f_difX -= 0.05f;
         if (f_difX < 0.5f) f_difX += 0.05f;

         transform.Rotate(Vector3.up, f_difX * i_direction);
     }
 }

Thanks.

I found a solution for whomever might need it:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SpinWheelScript : MonoBehaviour {

float pointerY;
float f_lastX = 0.0f;
float f_difX = 0.5f;
float f_steps = 0.0f;
int i_direction = 1;

void Start()
{
    pointerY = Input.GetAxis("Mouse Y");
}

void Update()
{

    if (Input.GetMouseButtonDown(0))
    {
        f_difX = 0.0f;
    }

    else if (Input.touchCount > 0)
    {
        pointerY = Input.touches[0].deltaPosition.y;
        f_difX = Mathf.Abs(f_lastX - pointerY);
        var touch = Input.GetTouch(0);

        if (touch.position.x > Screen.width / 2)
        {
            // Right
            if (f_lastX < Input.GetAxis("Mouse Y"))
            {
                i_direction = 1;
                transform.Rotate(Vector3.forward, f_difX * Time.deltaTime);
            }

            if (f_lastX > Input.GetAxis("Mouse Y"))
            {
                i_direction = -1;
                transform.Rotate(Vector3.forward, -f_difX * Time.deltaTime);
            }
        }
        else if (touch.position.x < Screen.width / 2)
        {
            // Left
            if (f_lastX < Input.GetAxis("Mouse Y"))
            {
                i_direction = -1;
                transform.Rotate(Vector3.forward, -f_difX * Time.deltaTime);
            }

            if (f_lastX > Input.GetAxis("Mouse Y"))
            {
                i_direction = 1;
                transform.Rotate(Vector3.forward, f_difX * Time.deltaTime);
            }
        }

        f_lastX = -pointerY;
        f_difX = 500f;
    Debug.Log(f_difX);
    }
    else
    {
        if (f_difX > 0.5f) f_difX -= 1f;
        if (f_difX < 0.5f) f_difX += 1f;

        transform.Rotate(Vector3.forward, f_difX * i_direction * Time.smoothDeltaTime);
    }
}
}

Currently, the object will spin based on a swipe along the Y axis, you can simple change it by replacing the Y’s with X’s. Also, i’ve modified the speeds to fit my liking. Hope this helps others.

Cheers!
