We've experienced problems with some high ranks (actually starting from 2 - lance corporal) which sometimes drop back to 0. My assumption is that connection problems are to blame. When player joins the game-server fetches his rank info from stat-server. But if it didn't fetch this info for some reason, then on end of round player will have a 0 PID. Again, this is only assumption. To fix this issue - i've limited maximal rank decrement to 1 point.. This won't protect Private First Class to be mistakenly driven back to Private. But as i've seen this is not a big problem since lance corporal is earned quite fast. NOTE: This patch includes my previous modification (correction 'None' fields). NOTE: Didn't tested it thoroughly, but the code is very simple and i don't think anything can go wrong Code: diff -Naur old/bf2statistics.php new/bf2statistics.php --- old/bf2statistics.php 2006-02-19 01:20:16.000000000 +0600 +++ new/bf2statistics.php 2006-05-07 13:49:00.754125000 +0700 @@ -62,6 +62,9 @@ // Get URL POST data $rawdata = file_get_contents('php://input'); +$rawdata = str_replace('\\None\\', '\\0\\', $rawdata); +set_time_limit(60); + // Seperate data $gooddata = explode('\\', $rawdata); @@ -263,6 +266,11 @@ // Calculate best round score $rndscore = ($row['rndscore'] > $data["rs_$x"]) ? $row['rndscore'] : $data["rs_$x"]; + // Assume that rank can't go down 2 points after a match + if ($data["rank_$x"] < $row['rank']-1) { + $data["rank_$x"] = $row['rank']; + } + // Calculate rank change $chng = $decr = 0; if ($data["rank_$x"] != $row['rank']) 1146985326_281_FT0_bf2statistics.zip
And yes, maybe there is a better way - apply a "Fix bot rank" block to all players instead of only to the bots, so stat-server calculaes ranks on it's own.This will solve problem once and for all
