Hi,
I recently followed the online tutorial step by step on how to save and load data using serialization, once I completed it and ran it (I have a button to save and a button to load) when the save button is pressed I can easily get to the file and see that in fact all the data has saved but when I try to load it again nothing happens all the data is once again reset to default values, the full code is below and I would really appreciate it if you could help in any way.
Code:
using UnityEngine;
using System.Collections;
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
using UnityEngine.UI;

}
