 using UnityEngine;
 using System.Collections;
 
 public class SwipeDetector : MonoBehaviour 
 {
     
     public float minSwipeDistY;
 
     public float minSwipeDistX;
         
     private Vector2 startPos;
 
     void Update()
     {
 //#if UNITY_ANDROID
         if (Input.touchCount > 0) 
             
         {
             
             Touch touch = Input.touches[0];
             
             
             
             switch (touch.phase) 
                 
             {
                 
             case TouchPhase.Began:
 
                 startPos = touch.position;
                 
                 break;
                 
                 
                 
             case TouchPhase.Ended:
 
                     float swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;

                     if (swipeDistHorizontal > minSwipeDistX)

                         if (swipeValue > 0)//right swipe

This link appears to be malware, I would avoid clicking on it

Seems like the domain is sold, the site displays weird Chinese fap games. I had just stopped being so paranoid about the links I click but now I'm back on it.
