Returning an IEnumerator as an int?

Questions & Answers
1

So what I am trying to do is, when I call the method in another class, I want to get the int from the coroutine, but I have hit a road block on how to do this. As you can see below I tried to do it, but I just can’t figure it out.

Eventually I want to store the int into a playerpref.

using UnityEngine;
using System.Collections;

public class TimerController : MonoBehaviour
{
    private string url = "mywebsite"; //timer php url
    public int unixTimeSeconds;

	void Start ()
	{
	}
	
    public void RequestTime()
    {
        StartCoroutine(GetTime());
    }

    public int ReturnTime(string urlwwwtext)
    {
        unixTimeSeconds = int.Parse(urlwwwtext);
        return unixTimeSeconds;
    }

    public IEnumerator GetTime()
    {
        WWW urlwww = new WWW(url);
        yield return urlwww;

        if (string.IsNullOrEmpty(urlwww.error))
        {
            //Debug.Log("server time: " + urlwww.text); //gets current unix timestamp since January 1, 1970
            //yield return urlwww.text;
            ReturnTime(urlwww.text);
        }
        else
        {
            Debug.Log("could not connect to my website, retrying");
            StartCoroutine(GetTime());
        }
    }
}

I like using callbacks for coroutines. The following is untested code, but demonstrates how to use a callback that takes a string as an argument, and how to do something with it.

    public void RequestTime()
    {
        StartCoroutine(GetTime((text)=>
        {
            if (!string.IsNullOrEmpty(text))
        		unixTimeSeconds = int.Parse(text);
        });
    }

    public IEnumerator GetTime(Action<string> callback)
    {
        WWW urlwww = new WWW(url);
        yield return urlwww;
 
        if (string.IsNullOrEmpty(urlwww.error))
        {
        	if (callback != null)
        		callback(urlwww.text);
        }
        else
        {
            Debug.Log("could not connect to my website, retrying");
            StartCoroutine(GetTime(callback));
        }
    }
