Export to WebGL save / load not working

Questions & Answers

I have a serlialisable class that I use to persist my data between sessions which works fine on mobile / desktop but does not work when exported to WebGL (Unity 2017)

[Serializable]
public class GameData
{
    public float CoinBalance = 0;
    public List<int> ItemCounts = new List<int>();
    public List<bool> ItemUnlocks = new List<bool>();
    public List<int> Upgrades = new List<int>();
    public List<int> UpgradeStates = new List<int>();
    public List<int> ModStates = new List<int>();
    public List<float> PowerupTimers = new List<float>();
    public List<bool> AchievementUnlocks = new List<bool>();
}

    public void SaveGame()
    {
        BinaryFormatter bf = new BinaryFormatter();
        FileStream file = File.Open(Application.persistentDataPath + "/gamedata.bin", FileMode.OpenOrCreate);
        bf.Serialize(file, GameData);
        file.Close();
    }

    void LoadGame()
    {
        if (File.Exists(Application.persistentDataPath + "/gamedata.bin"))
        {
            BinaryFormatter bf = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/gamedata.bin", FileMode.Open);
            _GameData = bf.Deserialize(file) as GameData;
            file.Close();
        }
    }

Its all pretty bog standard, but just does not work, no errors or exceptions, just doesn’t work.

I have another game exported from Unity 5.4 with similar data that works just fine when exported to WebGL. Has something broken in Unity 2017?

Ok, I don’t believe I have to do this in Unity 2017 but I have to resort to calling a bit of Javascript to force the file to sync FS.fsync(). WTF seriously? Anyway, it works but now I get a warning “warning: 2 FS.syncfs operations in flight at once, probably just doing extra work”, I’m assuming that it is already getting called somewhere but just not working?

Is the data saved so you can load the same data on another computer?
Or is it just saved on the computer you play on?
