The Player.IO Leaderboard service

To use Leaderboards in your game, you must first setup at least one Leaderboard Group. Each group needs an identifier, for example "score" or "laptime", and you need to set the sort order and deletion policy for the group.

A group can then contain one or more leaderboards, where each leaderboard is a sorted list of players by their score, sorted by the sort order of the group. If you leave the leaderboard identifier empty, PlayerIO will use the default leaderboard for the group. A leaderboard is automatically created by setting a player's score for a given leaderboard in a group, and you can use this to automatically have for example monthly leaderboards that "reset" each month

Here's how to set a player's score in the default leaderboard of the group "score":

Here's how to set a player's score in a monthly rotating leaderboard of the group "score":

Here's how to get the number of players in a default leaderboard:

Here's how to get the top 10 players in a default leaderboard:

By using the Count method you can find out how many entries there are in the entire leaderboard, and you can get the second page of 10 players by increasing the index parameter:

If you want to get the rank and score of a single player, pass in the connectuserid as a filter:

You can pass in multiple connectuserids to get a filtered list of only those players. For example, by passing in a list of friends of the current player, you can get a toplist for the friends. Don't forget to also pass in the connectuserid of the current player if you want his position as well:

The GetTop method starts at the top of the leaderboard, but if you want to know which players are immediately surrounding the current player, use the GetNeighbourhood method. The index parameter can be either positive or negative. If you use a negative number, the results will start above the current player, with better players, player who have a lower rank than the current player, and a better score. An index of 0 means the current player, and a positive index means that you start below the current player, with worse player, players who have a higher rank, and a worse score. For example, to get the 5 players above the current player, the current player himself, and the 5 players directly below, you can do this:

Finally, GetNeighbourhood also takes a list of players that you can use to filter the results, but unlike GetTop, the current player is always automatically included in the filter list. For example, if you have a long list of friends, but want to know which friend is immediately above the current player in the leaderboard, and which friend is immediately below the current player, you can do something like this:
