Question by JDRenais · Sep 28, 2018 at 01:01 AM · saveload

[Persistence] Saved To File, Not Updating

I was able to properly save a highscore and load it up; However, when the player reaches a new highscore, it doesn't update the saved value. It ends up showing the first highscore again.

 public void DiedAni()
     {
         if (File.Exists(Application.persistentDataPath + "/HighscoreData.HiZarrar"))
         {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Open(Application.persistentDataPath + "/HighscoreData.HiZarrar", FileMode.Open);
             PlayerData data = (PlayerData)bf.Deserialize(file);
             if (data.Highscore < Mathf.Floor(player.transform.position.z))
             {
                 data.Highscore = Mathf.Floor(player.transform.position.z);
                 bf.Serialize(file, data);
             }
             file.Close();
         }
         else
         {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Create(Application.persistentDataPath + "/HighscoreData.HiZarrar");
             PlayerData data = new PlayerData
             {
                 Highscore = Mathf.Floor(player.transform.position.z)
             };
             bf.Serialize(file, data);
             file.Close();
         }
 
         StartCoroutine(YeahIDied());
     }

If anyone could help, it'd be appreciated. I'm no longer working on this project but it would be good to know for future endeavors.

Looks like you're opening the file without write permissions.

Try changing this line: FileStream file = File.Open(Application.persistentDataPath + "/HighscoreData.HiZarrar", FileMode.Open); For this: FileStream file = File.Open(Application.persistentDataPath + "/HighscoreData.HiZarrar", FileMode.Open, FileAccess.Write);

I did as you said and it gave me an error: "The stream doesn't support reading."

Ups, I told you the wrong FileAcess. Try: FileAccess.ReadWrite.

That removed the error message but it still didn't update the value.
