Using the profile for advanced leaderboards

With PlayFab, you usually construct leaderboards using the following API methods:

• GetFriendLeaderboard
• GetFriendLeaderboardAroundPlayer
• GetLeaderboard
• GetLeaderboardAroundPlayer

The result is a list of PlayerLeaderboardEntry objects that contain only basic information about the player, and their relation to the current leaderboard.

However, PlayFab also allows you to use PlayerProfileViewConstraints, to gain additional information about each player.

Note

This example assumes you already have some leaderboard data to play with. Please refer to our Accessing Archived Tournament Results tutorial, for a method to generate some test data.

Configuring player profile view constraints

By default, the Client API may only fetch the display name from another player profile. In this example, we will allow all players to access additional information about other players in the leaderboard.

Navigate to your title Game Manager:

1. Select the Settings icon in the menu to the left.
2. Select Title settings
3. Then select the Client Profile Options tab.
4. Verify that the DisplayName is selected.
5. Make sure that the Avatar URL is selected.
6. Submit your changes by selecting the Save Client Profile Options button.

Testing

The previous step allows client code to use DisplayName and AvatarUrl profile constraints.

The following sample shows how to fetch and print a leaderboard using any mentioned Profile data. Please refer to the code comments for further information.

private static async Task DoReadLeaderboard()
{
    // Get Leaderboard Request
    var result = await PlayFabClientAPI.GetLeaderboardAsync(new GetLeaderboardRequest()
    {
        // Specify your statistic name here
        StatisticName = "TestScore",
        // Override Player Profile View Constraints and fetch player DisplayName and AvatarUrl
        ProfileConstraints = new PlayerProfileViewConstraints()
        {
            ShowDisplayName = true,
            ShowAvatarUrl = true
        }
    });

    // Start printing the leaderboard
    Console.WriteLine("=== LEADERBOARD ===");

    if (result.Error != null)
    {
        // Handle error if any
        Console.WriteLine(result.Error.GenerateErrorReport());
    }
    else
    {
        // Traverse the leaderboard list
        foreach (var entry in result.Result.Leaderboard)
        {
            // Print regular leaderboard entry information
            Console.WriteLine($"{entry.Position + 1} {entry.PlayFabId} {entry.StatValue}");

            // Additionally print display name and avatar url that comes from player profile
            Console.WriteLine($"    {entry.Profile.DisplayName} | {entry.Profile.AvatarUrl}");
        }
    }
}

Note

The individual Profile fields are only available if the client explicitly asks for them using Profile Constraints. Also be aware that if certain profile constraint are not allowed in the Game Manager - and your client requests them - the API call will fail with a corresponding error. The result will look similar to the example provided below.

Using this technique, you can fetch a handful of Profile information, including other statistic values.
