GameCenterPlatform - Load leaderboards with custom parameters

Question

Hello everyone :)

I'm implementing GameCenter using Unity's GameCenterPlatform.

I am aware of the default implementation using LoadScores, like the documentation suggests:

 Social.LoadScores("Leaderboard01", scores => {
     if (scores.Length > 0) {
         Debug.Log ("Got " + scores.Length + " scores");
         string myScores = "Leaderboard:\n";
         foreach (IScore score in scores)
             myScores += "\t" + score.userID + " " + score.formattedValue + " " + score.date + "\n";
         Debug.Log (myScores);
     }
     else
         Debug.Log ("No scores loaded");
 });

The documentation states:

This uses default leaderboard parameters.

Unfortunately I am not aware what these "default parameters" are, I'm not sure what scores is returned from the leaderboard. Is there anyone who is aware of a way to retrieve scores based on your own custom search query?

Thank you for your time :)

In Unity 5.6 you can do stuff like:

 void ShowScoresForToday()
 {
     // OutputField is a Unity text element I'm using to debug this on the device
     OutputField.text = "";
 
     var leaderboardID = "leaderboard";
     var log = string.Format( "Showing top score for leaderboard with id: '{0}'", leaderboardID );
     Debug.Log( log );
     OutputField.text = log;
 
     var leaderboard = Social.CreateLeaderboard();
     leaderboard.id = leaderboardID;
     leaderboard.timeScope = TimeScope.Today;
     leaderboard.LoadScores( success =>
     {
         var scores = leaderboard.scores;
         if ( scores.Length > 0 )
         {
             foreach ( var score in scores )
             {
                 var logLine = string.Format( "User with id '{0}' has a score of {1}, rank is {2}",
                     score.userID, score.value, score.rank );
                 OutputField.text += "\n" + logLine;
             }
         }
         else
         {
             Debug.LogError( "No scores registered" );
         }
     } );
 }

You have to initialize the Leaderboard object before querying, with the Social.CreateLeaderboard()

The filters are, hm, limited - https://docs.unity3d.com/ScriptReference/SocialPlatforms.ILeaderboard.html
