Help with Player Prefs "bug", it's urgent!

Hello!

I have a Player Prefs level unlock system, and the system it´s working, but the system have a "bug"...

When i play the level 1 i unlock the level 2, but if i play the level 1 again i unlock the level 3.... This is a big problem, because i don´t need to play the level 2 to unlock the level 3, i just need to play the level 1 twice.

How can I fix this?

I have 2 scripts, the player prefs and the game manager.

Player Prefs:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerPrefs_Manager : MonoBehaviour {
5.     public int Number_of_Levels = 1;
6.  
7.     // Use this for initialization
8.     void Start () {
9.  
10.         Debug.Log(PlayerPrefs.GetInt ("LevelsUnlocked"));
11.  
12.         //Adding the sound settings key
13.         if (!PlayerPrefs.HasKey ("SoundSettings"))
14.         {
15.             PlayerPrefs.SetInt ("SoundSettings", 1);
16.         }
17.  
18.         //Adding the key that holds the amount of levels the user has unlocked.
19.         if(!PlayerPrefs.HasKey ("LevelsUnlocked"))
20.         {
21.             PlayerPrefs.SetInt ("LevelsUnlocked", 1);
22.         }
23.  
24.  
25.         //Adding the key that holds what game mode the user
26.         //has selected.
27.  
28.         if(!PlayerPrefs.HasKey ("GameMode"))
29.         {
30.             PlayerPrefs.SetString("GameMode","Timed");  
31.         }
32.  
33.         CreateStars ();
34.  
35.     }
36.  
37.  
38.     void CreateStars()
39.     {
40.  
41.         for(int i = 0; i < Number_of_Levels; i++)
42.         {
43.             if(!PlayerPrefs.HasKey("Level" + i.ToString() + "Stars"))
44.             {
45.                 PlayerPrefs.SetInt("Level" + i.ToString() + "Stars",0);
46.             }
47.  
48.         }
49.  
50.  
51.  
52.     }
53. }

Game manager:

Code (CSharp):

1.  
2. public class GameManager : MonoBehaviour {
3.     public int LevelNumber;
4.     public GameObject imgStar1;
5.     public GameObject imgStar2;
6.     public GameObject imgStar3;
7.     public AudioClip audPickup;
8.     public AudioClip audWin;
9.     public AudioClip audCrash;
10.     //Panels
11.     public GameObject PausePanel;
12.     public GameObject PlayingPanel;
13.     public GameObject WinPanel;
14.     public GameObject LosePanel;
15.     public GameObject SettingsPanel;
16.     public Text txtGraphics;
17.     public Text MuteText;
18.  
19.     GameObject player;
20.  
21.     int StarsCollected;
22.     // Use this for initialization
23.     void Start () {
24.         player = GameObject.FindGameObjectWithTag("Player");
25.         Time.timeScale = 1;
26.         StarsCollected = 0;
27.  
28.  
29.         //Gets whether the sound is set to muted, and changes audio settings accordingly.
30.         if (PlayerPrefs.GetInt("SoundSettings") == 1)
31.         {
32.             AudioListener.pause = false;
33.             MuteText.text = "";
34.         } else if (PlayerPrefs.GetInt ("SoundSettings") == 0)
35.         {
36.             AudioListener.pause = true;
37.             MuteText.text = "/";
38.         }
39.  
40.         txtGraphics.text = GetQualityName (QualitySettings.GetQualityLevel());
41.     }
42.  
43.  
44.  
45. public    void CollectStar ()
46.     {
47.         audio.PlayOneShot (audPickup);
48.         StarsCollected += 1;
49.  
50.         if (StarsCollected == 1)
51.             imgStar1.SetActive (true);
52.         if (StarsCollected == 2)
53.             imgStar2.SetActive (true);
54.         if (StarsCollected == 3)
55.             imgStar3.SetActive (true);
56.  
57.     }
58.  
59.     public void CollectTime()
60.     {
61.         audio.PlayOneShot (audPickup);
62.     }
63.  
64.  
65. public void LevelWin ()
66.     {
67.         int lvlULTemp = PlayerPrefs.GetInt("LevelsUnlocked") + 1;
68.         PlayerPrefs.SetInt("LevelsUnlocked",lvlULTemp);
69.  
70.         Time.timeScale = 0;
71.         int tempStars = PlayerPrefs.GetInt ("Level" + LevelNumber.ToString () + "Stars");
72.         audio.PlayOneShot (audWin);
73.         if (tempStars < StarsCollected)
74.         {
75.             PlayerPrefs.SetInt ("Level" + LevelNumber.ToString () + "Stars", StarsCollected);
76.         }
77.  
78.         PausePanel.SetActive (false);
79.         PlayingPanel.SetActive (false);
80.         WinPanel.SetActive (true);
81.         LosePanel.SetActive (false);
82.         SettingsPanel.SetActive (false);
83.  
84.         }
85.  
86.  
87. public    void LevelLose()
88.     {
89.         player.audio.Stop();
90.         audio.PlayOneShot (audCrash);
91.         PausePanel.SetActive (false);
92.         PlayingPanel.SetActive (false);
93.         WinPanel.SetActive (false);
94.         LosePanel.SetActive (true);
95.         SettingsPanel.SetActive (false);
96.         Time.timeScale = 0;
97.         Debug.Log ("Level Lose");
98.     }

PS: I win the level when the "player" collides with the WinPanel.

Some help?

 

You need to increment the unlocked level only if you've just finished to last unlocked level, right ?

Code (CSharp):

1. int lvlULTemp = PlayerPrefs.GetInt("LevelsUnlocked");
2. if (lvlULTemp == LevelNumber)
3.     PlayerPrefs.SetInt("LevelsUnlocked",lvlULTemp+1);

 

Yes!

I have to put the code in Gamemanager.cs script in line 70?

Thank you

 

Thak you very much!

It works! Thanks a lot
