Local save (Reading from PlayerPrefv2.xml)

1. Parse the xml and get the key and value string pair, the string should look like xaHiFItVgoS6CBFNHTR2%2BA%3D%3D
2. URL decode it using System.Net.WebUtility.UrlDecode, to get the Base64 string (ex. xaHiFItVgoS6CBFNHTR2+A==)
3. Decrypt it using static function LocalSave.DecryptSaveStringNew(string base64EncodedString), there is also a model for score (RawScore, can be converted into a more dev-friendly format by calling ToInternalFormat method)
   • Example: LocalSave.DecryptSaveStringNew("eSB6QJlXU1vwHjVx7kcpb4/jdk9o5j4Wiatn+jrJ+etI2KFMlPDyH8s7I8zM+qlW")
   • Decrypted score string pair would be something like MARENOL.LeaF.0.Record.HD and {"s":992580,"a":99.17559051513672,"c":1}.
   • Note: the PlayerPrefv2.xml also contains other misc data, so you need to pick scores.
4. Once decrypted, you can do anything to the score data. <br/> Full example code:

public static CompleteScore ExampleDecryptLocal(string key, string data, float chartConstant) 
{
	string decryptedKey = LocalSave.DecryptSaveStringNew(WebUtility.UrlDecode(key));
	string decryptedData = LocalSave.DecryptSaveStringNew(WebUtility.UrlDecode(data));

	string[] splitted = decryptedKey.Split(".");
		string id = $"{splitted[0]}.{splitted[1]}";
		return
			JsonConvert.DeserializeObject<RawScore>(decryptedData)
				.ToInternalFormat(
					chartConstant,
					id,
					splitted[^1]
				);
}

// somewhere else in ur code...
ExampleDecryptLocal(@"Cgw4SttKwRFIjb68TF8z5EC%2FLwVpK8KjKmjcm9T3M78%3D", @"eSB6QJlXU1vwHjVx7kcpb4%2Fjdk9o5j4Wiatn%2BjrJ%2BetI2KFMlPDyH8s7I8zM%2BqlW", 11.4f);

Cloud Save

Common examples can be found there.

TapTap integration

See this for QRCode login example. There is also a callback login implementation, however it is limited since you can only callback to localhost (which means you cannot use this when you are hosting a server like a Discord bot.)

Fetching scores and other user info

Here is a short example of how to read scores from cloud save:

Save save = new(/* phigros token */);

// if you are using it in wasm project then you need to replace the decrypt function since
// aes doesn't work in browser environment:
// save.Decrypter = async (byte[] key, byte[] iv, byte[] data) => { /* your decrypting function here */ };
var context = await save.GetSaveContextAsync(/* save index, 0 for the latest save */);
context.ReadGameRecord(/* difficulties */).Records // all scores
context.ReadSummary() // summary info like username, level, etc.
context.ReadGameUserInfo() // in-game user info
// there's also other functions for reading different data, check the documentation for more info.

// as a function:
public static async Task<(Summary Summary, GameRecord Record)> GetLatestSave(string token, Dictionary<string, float[]> difficulties) 
{
	var helper = new Save(token);
	var context = await helper.GetSaveContextAsync(0);
	return (context.ReadSummary(), context.ReadGameRecord(difficulties));
}
// somewhere else in ur code...
await GetLatestSave("mysupersecrettoken1145141");

difficulties parameter should be a IReadOnlyDictionary<string, float[]>, the string would be song id, and float array for chart constants.<br/> The float array index should map to difficulty, from 0 to 3: EZ, HD, IN, then AT (fill value by 0 if AT difficulty doesn't exist). <br/> Example difficulty value pair: { "Credits.Frums", [1.0f, 8.5f, 14.0f, 0f] }
