Playerprefs

So i have a script that has a timer set up like this

Code (CSharp):

1. if (timeRemaining > 0)
2.                 {
3.                     timeRemaining -= Time.deltaTime;
4.                     DisplayTime(timeRemaining);
5.                  }
6.  
7. void DisplayTime(float timeToDisplay)
8.     {
9.         timeToDisplay += 1;
10.  
11.         float minutes = Mathf.FloorToInt(timeToDisplay / 60);
12.         float seconds = Mathf.FloorToInt(timeToDisplay % 60);
13.  
14.         timeText.text = string.Format("{0:00}:{1:00}", minutes, seconds);
15.     }

and i have a playerpref like this

Code (CSharp):

1. void OnDestroy()
2.     {
3.         PlayerPrefs.SetString(TimeLeft, timeText.text);
4.     }

my problem is that i have no clue on how to save the timer when i load a scene, since the timer is a text i dont know how to save it in the playerpref. any tips

 

You shouldn't save text. You should save timeToDisplay and generate text on load.

I don't want to talk about clever patterns and architecture, but always try to separate your game logic (so called "Model") and your "View".
Saving data should be called from your game logic, and it shouldn't rely on view, it shouldn't care about how your simple number will be formatted and shown to player. Today it's minutes and hours, next day it's something else, your saved data shouldn't become invalid because of view changes.

 

Every single bit that @Tekrel says above is 100% spot-on: understand the difference between the value (floating point) versus the presentation to the player (which could be text, string, UI, button, lever, arrow, image, clock dial, whatever).

Only save/load the value.

Here is a handy way to wrap up playerprefs to save stuff without having to sprinkle playerprefs calls all over your codebase:

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

Useful for a relatively small number of simple values.

 

Okay i am trying to save the timeToDisplay and make text at start but i have no clue what isnt working here can you pls help me

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class Timer : MonoBehaviour
7. {
8.     public float timeRemaining = 1800;
9.     public float timeReset = 1800;
10.     public bool timerIsRunning = false;
11.     public Text timeText;
12.     public Text counterText;
13.     float number = 0;
14.  
15.  
16.     string TimeLeft = "TimeOnLeave";
17.     string TimeDisplayTime = "TimeInDisplayTime";
18.     string HeartLeave = "HeartsOnLeave";
19.  
20.     void Start()
21.     {
22.         // Starts the timer automatically
23.         timerIsRunning = true;
24.         number = PlayerPrefs.GetFloat(HeartLeave);
25.         Debug.Log(PlayerPrefs.GetFloat(TimeLeft));
26.  
27.         float minutes = Mathf.FloorToInt(PlayerPrefs.GetFloat(TimeLeft) / 60);
28.         float seconds = Mathf.FloorToInt(PlayerPrefs.GetFloat(TimeLeft) % 60);
29.  
30.         timeText.text = string.Format("{0:00}:{1:00}", minutes, seconds);
31.     }
32.  
33.     void Update()
34.     {
35.         if (number <= 4)
36.         {
37.             if (timerIsRunning)
38.             {
39.                 if (timeRemaining > 0)
40.                 {
41.                     timeRemaining -= Time.deltaTime;
42.                     DisplayTime(timeRemaining);
43.                 }
44.                 else
45.                 {
46.                     Debug.Log("Time has run out!");
47.                     timeRemaining = timeReset;
48.                     timerIsRunning = true;
49.                     number += 1;
50.                 }
51.             }
52.  
53.             counterText.text = string.Format("{0}", number);
54.         }
55.         if(number == 5)
56.         {
57.             counterText.text = string.Format("FULL");
58.         }
59.     }
60.  
61.     public void DisplayTime(float timeToDisplay)
62.     {
63.         timeToDisplay += 1;
64.  
65.         float minutes = Mathf.FloorToInt(timeToDisplay / 60);
66.         float seconds = Mathf.FloorToInt(timeToDisplay % 60);
67.  
68.         timeText.text = string.Format("{0:00}:{1:00}", minutes, seconds);
69.  
70.         PlayerPrefs.SetFloat(TimeDisplayTime, timeToDisplay);
71.     }
72.  
73.     public void OnDestroy()
74.     {
75.         PlayerPrefs.SetFloat(TimeLeft, PlayerPrefs.GetFloat(TimeDisplayTime));
76.         PlayerPrefs.SetFloat(HeartLeave, number);
77.     }

 

Your class seems pretty small and simple. You can use debug.log or put breakpoint and walk step by step on every instruction checking all arguments.
Get used to figuring it out on your own, nobody will really help you with "this isn't working, I don't know why", this is programming, almost nobody will do your work for you.

I can only give you some more tips. Make smaller functions, give them better names, also you can separate Timer main logic from visual part and text operations, it will help you focus on algorithm/view separately. Sometimes it's really helpful, good refactoring and class separation unload your brain and make you think better.
