Data serialization method - Saving High Score Per Level & displaying on UI Text in Menu

Hi All

I need to update the HighScore Text with the new score for each level(scene) and make sure it remains there until the player gets a higher score, I am not sure of the correct method in accessing these UI texts (they are child of a UI button) from the scripts.

Attached UI image shows the buttons with their child components.
I need the text - "Highscore : "of HighScoreTextLvl01-14 to update when a highscore is made.


Here my build settings:




The console error received when animation is triggered for game over or win state:

ArgumentOutOfRangeException: Index must be >= 0 and <= Count.

Parameter name: index

15

System.Collections.ArrayList.ThrowNewArgumentOutOfRangeException (System.String name, System.Object actual, System.String message) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections/ArrayList.cs:3261)

System.Collections.ArrayList.Insert (Int32 index, System.Object value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections/ArrayList.cs:2940)

GameOverManager.Update () (at Assets/Resources/Scripts/Managers/GameOverManager.cs:36)


Here is the GameOverManager:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4. using System.Collections.Generic;
5. using System;
6. using System.Runtime.Serialization.Formatters.Binary;
7. using System.IO;
8.  
9. public class GameOverManager : MonoBehaviour
10. {
11.  
12.     public Slider energySlider;
13.     public Slider countDownSlider;
14.     public Slider lifeSlider;
15.  
16.     ArrayList highScores = new ArrayList();
17.     Animator anim;
18.  
19.  
20.  
21.     void Awake()
22.     {
23.         anim = GetComponent<Animator>();
24.     }
25.  
26.     void Update()
27.     {
28.      
29.         if(energySlider.value >= 300)
30.         {
31.             anim.SetTrigger("NextLevel");  
32.             int newScore = (int)ScoreManager.score; //get score and put it in int in newScore
33.             int rawlevelCount = Application.levelCount;
34.             int dontCountMenus = 2;
35.             int levelCount = rawlevelCount - dontCountMenus;
36.             highScores.Insert(levelCount, newScore);
37.             GameControl.control.highScores = highScores; //save current highscores to GameControl Highscores
38.             GameControl.control.Save(); //saveGame
39.         }
40.      
41.         if (countDownSlider.value >=300)
42.         {
43.             anim.SetTrigger("GameOver");
44.             int newScore = (int)ScoreManager.score; //get score and put it in int in newScore
45.             int rawlevelCount = Application.levelCount;
46.             int dontCountMenus = 2;
47.             int levelCount = rawlevelCount - dontCountMenus;
48.             highScores.Insert(levelCount, newScore);
49.             GameControl.control.highScores = highScores; //save current highscores to GameControl Highscores
50.             GameControl.control.Save(); //saveGame
51.         }
52.  
53.         if (lifeSlider.value <=0)
54.         {
55.                 anim.SetTrigger("GameOver");
56.             int newScore = (int)ScoreManager.score; //get score and put it in int in newScore
57.             int rawlevelCount = Application.levelCount;
58.             int dontCountMenus = 2;
59.             int levelCount = rawlevelCount - dontCountMenus;
60.             highScores.Insert(levelCount, newScore);
61.             GameControl.control.highScores = highScores; //save current highscores to GameControl Highscores
62.             GameControl.control.Save(); //saveGame
63.         }
64.     }
65.  
66. }
67.  

and here is my GameControl:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4. using System;
5. using System.Runtime.Serialization.Formatters.Binary;
6. using System.IO;
7.  
8. public class GameControl : MonoBehaviour {
9.     public static GameControl control;
10.  
11.     public int levelCount;
12.     public ArrayList highScores = new ArrayList();
13.  
14.  
15.     public void Save()
16.     {
17.         BinaryFormatter bf = new BinaryFormatter();
18.         FileStream file = File.Create(Application.persistentDataPath + "/playerInfo.dat");
19.      
20.         PlayerData data = new PlayerData();
21.         data.levelCount = levelCount;
22.         data.highScores = highScores;
23.  
24.         bf.Serialize(file, data);
25.         file.Close();
26.     }
27.     public void Load()
28.     {
29.         if(File.Exists(Application.persistentDataPath + "/playerInfo.dat"))
30.         {
31.             BinaryFormatter bf = new BinaryFormatter();
32.             FileStream file = File.Open(Application.persistentDataPath + "/playerInfo.dat", FileMode.Open);
33.             PlayerData data = (PlayerData)bf.Deserialize(file);
34.             file.Close();
35.          
36.             levelCount = data.levelCount;
37.             highScores = data.highScores;
38.         }
39.     }
40.  
41.     [Serializable]
42.     class PlayerData
43.     {
44.         public int levelCount;
45.         public ArrayList highScores;
46.     }
47. }

Finally here is my ScoreManager:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4. using System.Collections.Generic;
5.  
6. public class ScoreManager : MonoBehaviour
7. {
8.     public static int score;
9.     public static int energy;
10.  
11.     Text text;
12.  
13.     void Awake ()
14.     {
15.         text = GetComponent <Text> ();
16.         score = 0;
17.     }
18.  
19.     void Update ()
20.     {
21.         text.text = "Score: " + score;
22.     }
23. }

If anyone can help, it would be great. There are no tutorials showing how the data serialization works with the NEW UI, I watched this live training video 20.Live_Training_3_Mar_2014_-_Data_Persistence and it uses old GUI interface.

I don't want to use playerprefs as it isn't very secure.

Thanks

 

levelCount seems to be original unity API, did you intend to call that? if your setting it as a variable maybe try tweaking the name slightly, maybe its clashing with the internals. I've had that before and it caused a lot of problems, I see this is an older thread and would hope that you have solved this problem already but I noticed that by clicking on levelCount.
