Leaderboard

We've reached the last part of our Shooter Arena tutorial and we shall be implementing the worldwide leaderboard.

We shall be recording the number of wins and losses each user has and they shall be ranked by the difference. (wins - losses)

We shall be using Hasura Actions to automatically increase the wins column of the winner and the losses column of the loser depending on the battle data.

This way, users don't have permission to update their wins or losses columns, ensuring there is no cheating.
