setting highscores for multiple levels

what is the best way to set a high score for different scenes I have been working on playerprefs and binary formatter for days now I have tried to save the high score on my score text here

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Net;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using UnityEngine.SceneManagement;
7. using System.Runtime.Serialization.Formatters.Binary;
8. using System.IO;
9. using System;
10.  
11. public class Score : MonoBehaviour
12. {
13.     public float score = 0.0f;
14.     public float highscore;
15.     public float difficultyLevel = 1;
16.     public float maxDifficultyLevel = 10;
17.     public float scoreToNextLevel = 10;
18.     public Scene scene;
19.     public bool isDead = false;
20.  
21.     public Text scoreText;
22.     public DeathMenu deathMenu;
23.  
24.     // Start is called before the first frame update
25.     void Start()
26.     {
27.  
28.     }
29.  
30.     // Update is called once per frame
31.     void Update()
32.     {
33.         if (isDead)
34.             return;
35.  
36.         if (score > highscore)
37.         {
38.             highscore = score;
39.             scoreText.text = highscore.ToString(); ;
40.         }
41.  
42.         if (score >= scoreToNextLevel)
43.             LevelUp();
44.  
45.         score += Time.deltaTime * difficultyLevel;
46.         scoreText.text = ((int)score).ToString();
47.  
48.     }
49.  
50.     public void AddScore(int addedScorePoints)
51.     {
52.         score += addedScorePoints;
53.     }
54.  
55.     void LevelUp()
56.     {
57.         if (difficultyLevel == maxDifficultyLevel)
58.             return;
59.  
60.         scoreToNextLevel *= 2;
61.         difficultyLevel++;
62.  
63.         GetComponent<playermotor>().SetSpeed(difficultyLevel);
64.     }
65.  
66.     public void Save()
67.     {
68.         if (Directory.Exists(Application.dataPath + "/Save data/(scene.name)/") == false)
69.             Directory.CreateDirectory(Application.dataPath + "/Save data/(scene.name)/");
70.         BinaryFormatter bf = new BinaryFormatter();
71.         FileStream file = File.Create(Application.dataPath + "/Save data/(scene.name)/Score.secure");
72.         ScoreData data = new ScoreData();
73.        
74.         data.highscore = this.highscore;
75.  
76.         bf.Serialize(file, data);
77.         file.Close();
78.     }
79.  
80.     public void OnDeath()
81.     {
82.         isDead = true;
83.         deathMenu.ToggleEndMenu(score);
84.     }
85.  
86.     [Serializable]
87.     class ScoreData
88.     {
89.         public float highscore;
90.     }
91. }

I need it to save a separate high score for each scene which i tried to do with scene.name and I am trying to load the score on my level select screen here

Code (CSharp):

1. public class LevelSelect : MonoBehaviour
2. {
3.  
4.     public Text foresthscoreText;
5.     public Text deserthscoreText;
6.     public float score;
7.     public float highscore;
8.  
9.     // Start is called before the first frame update
10.     void Start()
11.     {
12.  
13.     }
14.  
15.     public void Load()
16.     {
17.         if (File.Exists(Application.dataPath + "/Save data/(scene.name)/Score.secure"))
18.         {
19.             BinaryFormatter bf = new BinaryFormatter();
20.             FileStream file = File.Open(Application.dataPath + "/Save data/(scene.name)/Score.secure", FileMode.Open);
21.             ScoreData data = (ScoreData)bf.Deserialize(file);
22.             file.Close();
23.  
24.             this.highscore = data.highscore;
25.             foresthscoreText.text = highscore.ToString();
26.         }
27.     }

I have been searching and trying on my own for days if anyone could help I would really appreciate it

 

This is a simpler example of the highscore system in a file. You can extend this.

Code (CSharp):

1. [Serializable]
2. public class Score
3. {
4.     public string Name { get; set; }
5.     public int Result { get; set; }
6. }
7.  
8. [Serializable]
9. public class ScenesHS
10. {
11.     public string SceneName { get; set; }
12.     public int IndexScene { get; set; }
13.     public List<Score> HS { get; set; }
14. }
15.  
16. public class HighS
17. {
18.     List<ScenesHS> scenesHighScores = new List<ScenesHS>();
19.  
20.     //only to test my program
21.     public void PopulateScores()
22.     {
23.         string nameDict = "abcdefghijklmn";
24.         for (int scene = 0; scene < 10; scene++)
25.         {
26.             string name = "" + nameDict[scene];
27.  
28.             ScenesHS shs = new ScenesHS();
29.             shs.HS = new List<Score>();
30.             shs.SceneName = name;
31.             shs.IndexScene = scene;
32.  
33.             for (int highScores = 0; highScores < 5; highScores++)
34.             {
35.                 shs.HS.Add(new Score { Name = name + highScores.ToString(), Result = highScores * 5 });
36.             }
37.             scenesHighScores.Add(shs);
38.         }
39.     }
40.  
41.     //from https://docs.microsoft.com/en-us/dotnet/api/system.runtime.serialization.formatters.binary.binaryformatter.deserialize?view=netframework-4.8
42.     public void Save()
43.     {
44.         FileStream fs = new FileStream("DataFile.dat", FileMode.Create);
45.  
46.         // Construct a BinaryFormatter and use it to serialize the data to the stream.
47.         BinaryFormatter formatter = new BinaryFormatter();
48.         try
49.         {
50.             formatter.Serialize(fs, scenesHighScores);
51.         }
52.         catch (SerializationException e)
53.         {
54.             Console.WriteLine("Failed to serialize. Reason: " + e.Message);
55.             throw;
56.         }
57.         finally
58.         {
59.             fs.Close();
60.         }
61.     }
62.  
63.     //from https://docs.microsoft.com/en-us/dotnet/api/system.runtime.serialization.formatters.binary.binaryformatter.deserialize?view=netframework-4.8
64.     public void Load()
65.     {
66.         scenesHighScores = null;
67.  
68.         // Open the file containing the data that you want to deserialize.
69.         FileStream fs = new FileStream("DataFile.dat", FileMode.Open);
70.         try
71.         {
72.             BinaryFormatter formatter = new BinaryFormatter();
73.  
74.             // Deserialize the hashtable from the file and
75.             // assign the reference to the local variable.
76.             scenesHighScores = (List<ScenesHS>)formatter.Deserialize(fs);
77.         }
78.         catch (SerializationException e)
79.         {
80.             Console.WriteLine("Failed to deserialize. Reason: " + e.Message);
81.             throw;
82.         }
83.         finally
84.         {
85.             fs.Close();
86.         }
87.  
88.         // To prove that the table deserialized correctly,
89.         // display the key/value pairs.
90.         foreach (var x in scenesHighScores)
91.         {
92.             Console.WriteLine($"SceneName: {x.SceneName}, IndexScene: {x.IndexScene}");
93.             foreach (var h in x.HS)
94.             {
95.                 Console.WriteLine($"Name: {h.Name}, Score: {h.Result}");
96.             }
97.         }
98.     }
99. }

 

i put in what you said and i get this error when i switch public class score: monobehavior to public class HighS
error CS0246: The type or namespace name 'SerializationException' could not be found (are you missing a using directive or an assembly reference?)

and if i leave it the way it is i get this error
error CS0101: The namespace '<global namespace>' already contains a definition for 'Score' because it has the same name as your line 2 in your code.

 

You need to use [Serialize]
You have another class with the name Score
