"PlayerPrefs.SetValue" Not Working Properly?

Unity Engine

Hey Unity! I’m trying to make a script to count the playtime of the player.

using UnityEngine;
using TMPro;

public class PlaytimeCounter : MonoBehaviour
{
    //Le Variables
    private float playSeconds;
    private float playMinutes;
    private float playHours;
    private float playDays;

    //Starting Value If New
    private const int startTimeCount = 0;

    //Le Displays
    public TextMeshPro SecondsDisplay;
    public TextMeshPro MinutesDisplay;
    public TextMeshPro HoursDisplay;
    public TextMeshPro DaysDisplay;

    void Start()
    {
        //Loads values if exist, else set to starting value
        playSeconds = PlayerPrefs.GetFloat("", startTimeCount);
        playMinutes = PlayerPrefs.GetFloat("", startTimeCount);
        playHours = PlayerPrefs.GetFloat("", startTimeCount);
        playDays = PlayerPrefs.GetFloat("", startTimeCount);
    }

    void Update()
    {
        //Update time
        playSeconds += Time.deltaTime;

        //Update other values if overlap
        if (playSeconds > 59)
        {
            playMinutes += 1;
            playSeconds = 0;
        }
        if (playMinutes > 59)
        {
            playHours += 1;
            playMinutes = 0;
        }
        if (playHours > 23)
        {
            playDays += 1;
            playHours = 0;
        }

        //Save the values
        PlayerPrefs.SetFloat("", playSeconds);
        PlayerPrefs.SetFloat("", playMinutes);
        PlayerPrefs.SetFloat("", playHours);
        PlayerPrefs.SetFloat("", playDays);

        //Update the displays
        int DisplaySeconds = Mathf.CeilToInt(playSeconds);
        SecondsDisplay.text = "Seconds: " + DisplaySeconds.ToString();
        int DisplayMinutes = Mathf.CeilToInt(playMinutes);
        MinutesDisplay.text = "Minutes: " + DisplayMinutes.ToString();
        int DisplayHours = Mathf.CeilToInt(playHours);
        HoursDisplay.text = "Hours: " + DisplayHours.ToString();
        int DisplayDays = Mathf.CeilToInt(playDays);
        DaysDisplay.text = "Days: " + DisplayDays.ToString();
    }
}

For some reason, every time I test this, none of the four values save. Does anyone know why this is?

The empty quotes here demonstrate that you haven’t finished writing your code.

If it isn’t immediately clear to you why I say this, go work through some simple PlayerPrefs tutorials rather than trying to make it up as you go. It will save you a lot of time and effort.

After you understand the basics of how to use the PlayerPrefs API, read onto this:

Here’s an example of simple persistent loading/saving values using PlayerPrefs:

Useful for a relatively small number of simple values.

Well spotted, my eyes glossed over that. Maybe my brain was in denial. :slight_smile:
