Creating level Buttons and Assigning stars

I'm working on a game and I'm facing a problem at level selection. I have script for creating level buttons it was working fine unless I'd added a new mode every thing is fine the problem is when I show stars on level button stars from 2nd level of simple mode gets equal to the first level of classic mode for example I have 2 stars on 2nd level of simple mode then the stars of first level of classic mode becomes equal to that. Can any one help me with it
Code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using TMPro;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using UnityEngine.SceneManagement;
7.  
8. public class LevelManager : MonoBehaviour
9. {
10. public GameObject loadingPanel;
11.  
12. public int numberOfSimpleLevels;
13. public int numberOfClassicLevels;
14.  
15. public GameObject levelButton;
16. public Transform content;
17.  
18. List<GameObject> levelButtons;
19.  
20. public string simpleModeScene;
21.  
22. public static LevelManager instance;
23.  
24. private void Start()
25. {
26.    if (instance == null)
27.    {
28.        instance = this;
29.    }
30.    levelButtons = new List<GameObject>();
31. }
32.  
33. public void SimpleModeButton()
34. {
35.    CommonInfos.selectedMode = Mode.SimpleMode;
36.    CreateButtons(CommonInfos.selectedMode, numberOfSimpleLevels);
37. }
38. public void ClassicModeButton()
39. {
40.    CommonInfos.selectedMode = Mode.ClassicMode;
41.    CreateButtons(CommonInfos.selectedMode, numberOfClassicLevels);
42. }
43.  
44. public void CreateButtons(Mode mode, int totalLevels)
45. {
46.  
47.    foreach (var item in levelButtons)
48.    {
49.        Destroy(item);
50.    }
51.    levelButtons.Clear();
52.  
53.    for (int i = 0; i < totalLevels; i++)
54.    {
55.        GameObject btn = Instantiate(levelButton, content);
56.        btn.SetActive(true);
57.        btn.name = i.ToString();
58.        levelButtons.Add(btn);
59.    }
60.    SetButtons(mode);
61. }
62.  
63.  
64. public void SetButtons(Mode mode)
65. {
66.    Debug.Log(PlayerPrefs.GetInt(mode + CommonInfos.unlockedLevels, 0));
67.    for (int i = 0; i < levelButtons.Count; i++)
68.    {
69.        if (i <= PlayerPrefs.GetInt(mode + CommonInfos.unlockedLevels, 0))
70.        {
71.            int index = i;
72.            levelButtons[i].GetComponent<Button>().onClick.AddListener(() => SceneToLoad(index));
73.            levelButtons[i].transform.Find("text").gameObject.GetComponent<TextMeshProUGUI>().text = (i + 1).ToString();
74.            levelButtons[i].transform.Find("lockImg").gameObject.SetActive(false);
75.            int stars = PlayerPrefs.GetInt(mode + index + "levelStars", 3);
76.            switch (stars)
77.            {
78.                case 2:
79.                    levelButtons[i].transform.Find("1").gameObject.SetActive(true);
80.                    levelButtons[i].transform.Find("2").gameObject.SetActive(false);
81.                    levelButtons[i].transform.Find("3").gameObject.SetActive(false);
82.                    break;
83.  
84.                case 1:
85.                    levelButtons[i].transform.Find("1").gameObject.SetActive(true);
86.                    levelButtons[i].transform.Find("2").gameObject.SetActive(true);
87.                    levelButtons[i].transform.Find("3").gameObject.SetActive(false);
88.                    break;
89.  
90.                case 0:
91.                    levelButtons[i].transform.Find("1").gameObject.SetActive(true);
92.                    levelButtons[i].transform.Find("2").gameObject.SetActive(true);
93.                    levelButtons[i].transform.Find("3").gameObject.SetActive(true);
94.                    break;
95.  
96.                default:
97.                    levelButtons[i].transform.Find("1").gameObject.SetActive(false);
98.                    levelButtons[i].transform.Find("2").gameObject.SetActive(false);
99.                    levelButtons[i].transform.Find("3").gameObject.SetActive(false);
100.                    break;
101.            }
102.        }
103.    }
104. }
105.  
106. public void SceneToLoad(int index)
107. {
108.    CommonInfos.levelToLoad = index;
109.    loadingPanel.SetActive(true);
110. }
111.  
112. }

I have also checked the PlayerPrefs value of that level it remains same and some how changes in SetButtons function

 

This seems like a programming problem rather than a game design one. Try asking in the Scripting sub-forum instead.
