PlayerPrefs not saving my variable value for HighScore System

Question

Ok, so I have this code in my restart scene for setting up a highScore variable, if its bigger than the previous one.

 private var scoreSaver : float;// Time of survive
 private var playerHighScore : float; // Time of survive for highscore uses
 private var storeHighScore : float = 0;
 
 function Start ()
 {
     scoreSaver =  PlayerPrefs.GetFloat("Time Survived"); //Retrieves my survive time of previous code(I've set up it correctly in other code)
     playerHighScore = PlayerPrefs.GetFloat("High Score"); Retrieves my survive time of previous code. Equals above, but I need two of this timer, because one of them resets every restart button click.
     if (scoreSaver >= playerHighScore && scoreSaver >= storeHighScore)
     {
         
         storeHighScore = playerHighScore;
         
     }

}

In the restart button, I have this:

 PlayerPrefs.DeleteKey("Time Survived");

The problem is that every time I play, the storeHighScore doesn't get its value, it gets reseted, so I'm always having a new highScore, event if its lower than the previous one

Finally I fixed it. It's pretty logic and simple now.

private var timeSurvived : float;

 function Awake()
 { 
     var highScore = PlayerPrefs.GetFloat("highScore"); 
     timeSurvived = PlayerPrefs.GetFloat("timeSurvived");    
     
     if (timeSurvived > highScore)
     {
         PlayerPrefs.SetFloat("highScore", timeSurvived);
     }    
 }

My problem was assigning the highScore variable, but I've discovered I needed to make it equals to PlayerPref highScore float. After that, I did not have any other problems. This also doesn't creates multiple playerPreference.

 if(PlayerPrefs.HasKey("HScore"))
 {
     if(PlayerPrefs.GetInt("HScore")<curScore)
         { 
             PlayerPrefs.SetInt("HScore", curScore);
             
         }
 }else{
     PlayerPrefs.SetInt("HScore",curScore);
 }

Follow a similar structure to prevent new highscores being set all the time.

Make a separate gameObject called HighScoreKeeper or something with a script which reads the

  public var playerHighScore

from your above script.

if you have something like on whatever is keeping score:

     function Update()
     {
             currentScore = //whatever;
     
             if ( currentScore >= highScoreKeeper.GetComponent(highScoreScript).highScore )
             (
                 playerHighScore = currentScore;
             }
 
     }

then in HighScoreKeeper object have something like:

public var highScore : int = 0; var pHighScore : int = 0;

 function Update()
 {
      pHighScore = scoringObject.GetComponent(scoringScript).playerHighScore;
 
      if ( pHighScore >= highScore )
      {
          highScore = pHighScore;
      }
                    
         
 }
