I am not very familiar with writing and reader files yet, so I’m having a tough time figuring this out.

Using StreamWriter, I’m writing the following to a .text file:

UpgradePointsTotalAmount = 5250

Now I need to retrieve the number only, by first checking if “UpgradePointsTotalAmount” exists, and then returning its value.

How would I do that using StreamReader?

Thanks in advance for your time!

Try this out:

using UnityEngine;
using System.Collections;
using System.Text.RegularExpressions;

public class regex : MonoBehaviour 
{
	public string s = "afsdlk 10 sdfalkj 30";
	
	// Update is called once per frame
	void Start()
	{
		string[] numbers = Regex.Split(s, @"\D+");
		foreach (string value in numbers)
		{
			if (!string.IsNullOrEmpty(value))
			{
			int i = int.Parse(value);
			Debug.Log("Number: " + i);
			}
		}
	}
}

I wrote this code by adapting the example from this site: http://www.dotnetperls.com/get-numbers-from-string
