Saving data between scenes and games using PlayerPrefs

While the previous recipe illustrates how the static properties allow a game to remember values between different scenes, these values are forgotten once the game application is exited. Unity provides the PlayerPrefs feature to allow a game to store and retrieve data between the different game-playing sessions.

Getting ready

This recipe builds upon the previous recipe, so make a copy of that project and work from it.

How to do it...

To save and load the player data using PlayerPrefs, follow these steps:

1. Delete the C# script PlayerData.
2. Edit the C# script called UpdateScoreText by replacing the Start() method with the following code:

   void Start(){
      int scoreCorrect = PlayerPrefs.GetInt("scoreCorrect");
      int scoreIncorrect = PlayerPrefs.GetInt("scoreIncorrect");
      int totalAttempts = scoreCorrect + scoreIncorrect;
      string scoreMessage = "Score = ";
     ...
