Unity GameObject SetActive save to playerprefs

Question

I want to save the active state of each individual gameobject so when you reload, the ones you collected won't be there anymore. My code :

public class PlayerController : MonoBehaviour {

     public LevelManager levelManager;          
     public GameObject[] stardust; //array of stardust in level
     public int isActive; //variable for amount of stardust collected

     void Start()
     {            
         isActive = PlayerPrefs.GetInt("stardust");
         active();
     }

     void OnTriggerEnter(Collider other)
     {    
         //Stardust
         if (other.gameObject.CompareTag("stardust"))
         {
             isActive = 1;
             PlayerPrefs.SetInt("stardust", isActive);           
             active();
             //other.gameObject.SetActive(false);
             levelManager.score++;
             levelManager.setScoreText();
             audioSource.Play();
             PlayerPrefs.SetInt("score", levelManager.score);
         }
     }

     void active()
     {
         if (isActive == 0) //if none are collected
         {
             for (int i = 0; i < stardust.Length; i++)
             {
                 stardust[i].SetActive(true); //make all visible
             }
         }
         if (isActive == 1) //first one collected
         {
             stardust[0].SetActive(false);
             stardust[1].SetActive(false);
             stardust[2].SetActive(false);
         }    
     }
 }

As you can see it sets all of the objects to inactive, how do I check for each one individually ?

I am using a single key in playerprefs for all stardust. Should I rather set a key for each stardust ?

I tried comparing each one by tag, under EventTrigger, with each their own method checking each and setting Active individually to no success

hi Curstin Visagie, it wont work with single key,the playerprefs values will be overwritten ,you have to create each key for each stardust.
