title: Unity 5 PlayerPrefs
body: <p>I tried in very much ways, but I really can't figure it out. This is a level lock/unlock system made by me. On my PC works perfectlly, but when I test it on my android smartphone nothing works. Why ? If I will use PlayerPrefs will work ? How I should use PlayerPrefs ? Because I tried in very much ways and no result.</p>
  
  <p>Here is my script:</p>
  
  <pre><code>using UnityEngine;
  using System.Collections;
  
  public class LevelLockSystem : MonoBehaviour {
  
      public GameObject unlockLevel2;
      public GameObject unlockLevel3;
      public GameObject unlockLevel4;
      public GameObject unlockLevel5;
      public GameObject unlockLevel6;
      public GameObject unlockLevel7;
      public GameObject unlockLevel8;
      public GameObject unlockLevel9;
      public GameObject unlockLevel10;
  
      public void Start()
      {
  
      }
  
      public void LockAllLevels()
      {
          unlockLevel2.SetActive(true);
          unlockLevel3.SetActive(true);
          unlockLevel4.SetActive(true);
          unlockLevel5.SetActive(true);
          unlockLevel6.SetActive(true);
          unlockLevel7.SetActive(true);
          unlockLevel8.SetActive(true);
          unlockLevel9.SetActive(true);
          unlockLevel10.SetActive(true);
      }
      public void UnlockLevel2()
      {
          unlockLevel2.SetActive(false);
      }
      public void UnlockLevel3()
      {
          unlockLevel3.SetActive(false);
      }
      public void UnlockLevel4()
      {
          unlockLevel4.SetActive(false);
      }
      public void UnlockLevel5()
      {
          unlockLevel5.SetActive(false);
      }
      public void UnlockLevel6()
      {
          unlockLevel6.SetActive(false);
      }
      public void UnlockLevel7()
      {
          unlockLevel7.SetActive(false);
      }
      public void UnlockLevel8()
      {
          unlockLevel8.SetActive(false);
      }
      public void UnlockLevel9()
      {
          unlockLevel9.SetActive(false);
      }
      public void UnlockLevel10()
      {
          unlockLevel10.SetActive(false);
      }
  
  }
  </code></pre>
