How to add a new string in a list of strings AND serialize the list everytime a new string is added to the list?

Questions & Answers

So basically I want the add a new string to a list every time my player achieve a score and be able to save it. So when the player turn the game back on, the new string is still in the list.

.

(The strings in the list is the name on levels, so every time I am adding a new string, I am adding a new level). In case you want to know what the strings does.

Hey Everyone who followed this Question … I think I got the ANSWER…

THAT IS MY SCRIPTS… when I want to save it ( you guys can change the condition when you want to save it).

 if (Input.GetKeyDown(KeyCode.Q) )
        {           
            if (!ScoreManager.GetInstance(). Levelnames.Contains("levels"))
            {
                ScoreManager.GetInstance().Levelnames.Add("levels");
            }
            else
            {
                return;
            }
            ScoreManager.GetInstance().Save();               
        }

        if (Input.GetKeyDown(KeyCode.E))
        {         
            if (!ScoreManager.GetInstance().Levelnames.Contains("Main Menu"))
            {
                ScoreManager.GetInstance().Levelnames.Add("Main Menu");
            }
            else
            {
                return;  
            }
            ScoreManager.GetInstance().Save();
        }

the Saving and loading scripts( the scripts is a dontdestroyOn because of my particular game. That is why you have ScoreManager.GetInstance. save(); in the above script, because I am calling the save method from the below script.)

 public List<string> Levelnames = new List<string>();

public void Save()
    {
        BinaryFormatter BF = new BinaryFormatter();
        FileStream file = File.Create(Application.persistentDataPath + "/PlayerInfo.dat");

        PlayerData data = new PlayerData();

           data.NewLevelnames = Levelnames;

        BF.Serialize(file, data);
        file.Close();
    }

    public void load()
    {
        if (File.Exists(Application.persistentDataPath + "/PlayerInfo.dat"))

        {
            BinaryFormatter BF = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/PLayerInfo.dat", FileMode.Open);

            PlayerData data = (PlayerData)BF.Deserialize(file);
            file.Close();

                    Levelnames = data.NewLevelnames;
        }
        
    }
}

[Serializable]
class PlayerData
{
    public List<string> NewLevelnames = new List<string>();
}

Hope it help… Peace out… :slight_smile:
