Square mod library : Scoreboard
2013/02/10 By TOJTeam
Get scoreboard by rank :
sqlib_scoreboard::get_scoreboard($sqlc, $msqlc, $sqid, $sboard_id, $score_func, $start_time, $end_time, $start_rank, $number)
Get scoreboard of specific user :
sqlib_scoreboard::get_scoreboard_uid($sqlc, $msqlc, $sqid, $sboard_id, $score_func, $start_time, $end_time, $uid)
$sqlc : sql connection to database 'toj'
$msqlc : sql connection to database 'toj_mod'
$sqid : square id number
$sboard_id : scoreboard id number (of square)
$score_func : function to determine rank_score
$start_time : start timestamp
$end_time : end timestamp
$start_rank : display from which rank
$number : number to display
$uid : user id number
Parameter format of $score_func:
func($sqid, $proid, $best_score, $best_time, $is_ac, $ac_time, $tries_before_ac, $last_score, $last_status, $tries);
