Commands

Examples

Let's say you need to store Diablo 3 player scores and need to filter character and country.

First we need to connect LeaderboardDB with resp.

redis-cli -p 6488

And then we need to add users to diablo_3 leaderboard.

add diablo_3 user_1 100 character wizard country tr
add diablo_3 user_2 105 character monk country tr
add diablo_3 user_3 95 character monk country tr
add diablo_3 user_4 95 character monk country us
add diablo_3 user_5 96 character demon_hunter country us

If you need to get all users in this leaderboard playing monk.

leaderboard diablo_3 0 -1 character monk

Response will be:

1) "user_2"
2) "user_3"
3) "user_4"

Or maybe you need to get all monk player in some country.

leaderboard diablo_3 0 -1 character monk country tr

Then response will be:

1) "user_2"
2) "user_3"

Or maybe you don't need any filter

leaderboard diablo_3 0 -1

Then response will be:

1) "user_2"
2) "user_1"
3) "user_5"
4) "user_3"
5) "user_4"
