Hand spinner script

Question

Hello guys, today i am trying to make hand spinner game (screenshot) So i am using this script as a test to test the rotation : my question here is how i can get the speed from user without adding it as a variable inside the script. is there a function to call ? please help i am stuck

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Spin : MonoBehaviour {
 
     public float speed = 10f;
     public float Zaxis = 5f;
     // Use this for initialization
     void Start () {
 
     }
 
     // Update is called once per frame
     void Update () {
 
         if (Input.GetKey("up"))
             RotateLeft();
     }
 
     void RotateLeft () {
         transform.Rotate (0, 0, Zaxis * Time.deltaTime);
     }
 
 }

You don't want to use 'if (Input.GetKey("up"))' because there is no key associated with mobile. You're looking for 'input.GetTouch' then calculate how fast the fingers are moving and apply it to your RotateLeft:

https://docs.unity3d.com/ScriptReference/Input.GetTouch.html

 using UnityEngine;
 using System.Collections;
 
 public class ExampleClass : MonoBehaviour
 {
     public float speed = 0.1F;
     void Update()
     {
         if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved)
         {
             // Get movement of the finger since last frame
             Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
 
             // Move object across XY plane
             transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);
         }
     }
 }
