The user encountered this problem and gave me this archive.
Can I view the data in savadata? I tried to open it with the TXT document and it was empty.
Please tell me what data is in savadata

My English is not good. It ’s all translated by Google. I hope you understand.

Hi there,

The save file your customer has sent you is empty, which is why you are getting the error message. This most commonly happens because the file is in a folder which is automatically stored to cloud, but the contents of the file have not been downloaded from the cloud.

It might also happen if there is not enough space in their harddrive to store the data, but an exception would be thrown when saving if this was the case.

All the best,
Joel

Thank you for your reply

Code: Select all

static public void SaveData()
    {
        ES3.Save<bool>("Tip", Data.IsTip, Data.SaveDataPath);
        ES3.Save<bool>("Complete", Data.IsCompleted, Data.SaveDataPath);
        ES3.Save<int>("CurrentID", Data.CurrentID, Data.SaveDataPath);
        ES3.Save<int>("HighestID", Data.HighestID, Data.SaveDataPath);
        ES3.Save<float>("SoundValue", SoundMgr.Inst.audioSource.volume, Data.SaveDataPath);
    }
}

1.According to you, if I keep them separately one by one, will it reduce the occurrence of a problem? Do you have a better suggestion? For example, recommend some apis.
2.How can I judge whether the archive is empty (broken) so that I can repair the archives of those users

Hi there,

This issue does not occur at our end but instead will occur at the customers end, so it's not something that we would be able to prevent.

The best way to detect the issue is simply to catch the InvalidDataException. If you want to be certain that it's because of corrupt data, you can use ES3.LoadRawString to get the contents of the file and check that it's not null.

All the best,
Joel
