PlayerPrefsX IntArray

Question

I keep getting the error of index out of range exception for PlayerPrefsX Int Array. I want to replace the $$anonymous$$ghscore whenever score is $$anonymous$$gher. Here are my codes:

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class ScoreManager : MonoBehaviour 
 {
     public static int score;
     public static int[] $$anonymous$$ghScores = new int[2];
     public Text scoreText;
     public Text $$anonymous$$ghScoreText;
 
     void Awake ()
     {
         score = 0;
         if (PlayerPrefs.HasKey ("HighScore"))
             $$anonymous$$ghScores = PlayerPrefsX.GetIntArray ("HighScore");
         PlayerPrefsX.SetIntArray ("HighScore", $$anonymous$$ghScores);
     }
 
     void Update ()
     {
         if (Time.timeScale == 0)
         {
             scoreText.text = "Score: " + score;
             $$anonymous$$ghScoreText.text = "High Score: " + $$anonymous$$ghScores [Application.loadedLevel - 1];
             
             if ($$anonymous$$ghScores [Application.loadedLevel - 1] > PlayerPrefsX.GetIntArray ("HighScore") [Application.loadedLevel - 1])
                 PlayerPrefsX.SetIntArray ("HighScore", $$anonymous$$ghScores);
         }
     }
 }

A function from another class:

 void Score ()
 {
     if (count > ScoreManager.$$anonymous$$ghScores [Application.loadedLevel - 1])
         ScoreManager.$$anonymous$$ghScores [Application.loadedLevel - 1] = count;
     ScoreManager.score = count;
 }

Do not use PlayerPrefsX. I have used it and it didn't work as expected when using multiple arrays. Instead build your own with PlayerPrefs. Here is what I have used in one of my projects. I have modified it for your purpose.

 // Use t$$anonymous$$s to set integer array
 public static void SetHighScores (int[] $$anonymous$$ghScores)
 {
     PlayerPrefs.SetString ("HighScore", GetSerializedString($$anonymous$$ghScores));
 }
 
 // Use t$$anonymous$$s to get integer array
 public static int[] GetHighScores ()
 {
     string[] data = PlayerPrefs.GetString ("HighScore", "0").Split ('|');
     int[] val = new int[data.Length];
     int score;
     for (int i = 0; i < val.Length; i++)
     {
         val[i] = int.TryParse(val[i], out score) ? score : 0;
     }
     return val;
 }
 
 private static string GetSerializedString (int[] data)
 {
     if (data.Length == 0) return string.Empty;
     
     string result = data [0].ToString ();
     for (int i = 1; i < data.Length; i++)
     {
         result += ("|" + data[i]);
     }
     return result;
 }

You may use stringbuilder in GetSerializedString for optimal performance.

Yes, sorry! I changed it on the fly.

Change that line to:

 val[i] = int.TryParse(data[i], out score) ? score : 0;
