Help with the swipe script

Hello to everyone, I have some trouble to find out why the player don’t swipe left, right, up and down.
Basically this is an asset that I bought and is a infinite runner but the support for the asset does not exist.

This is the code

using UnityEngine;
using System.Collections;
using UnityStandardAssets.CrossPlatformInput;

Sounds like you wrote a bug… and that means… time to start debugging!

By debugging you can find out exactly what your program is doing so you can fix it.

Use the above techniques to get the information you need in order to reason about what the problem is.

You can also use Debug.Log(...); statements to find out if any of your code is even running. Don’t assume it is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.
