Question

In a turn-based game, I’d like to find the previous player.
To find the next player, I can just type:

int lastPlayer = match.currentPlayer - 1;

The problem is when the currentPlayer is player 1. Then lastPlayer becomes 0, which is wrong. It should be player6.

To fix this, I can do:

    int lastPlayer = match.currentPlayer - 1;

    if (lastPlayer == 0)
        lastPlayer = match.numberOfPlayers;

My question is how to write this in a cleaner way. I know game center, turn based code do something like:

    (currentIndex + 1) % match.participants.count];

How can I rewrite my code to do the same?

Thanks in advance

Answer 1

How about that?

int lastPlayer = match.currentPlayer > 1 ? match.currentPlayer - 1 : match.numberOfPlayers;
