    Hi people, in this tutorial we are going to add a leaderboard system where we will display the total scores in a table which you earned by playing some games which give you score. First of all, we need to make some service-side changes and then move onto the web-side changes. This is a simple system, so first open your database and click the table 'penguins' and create a column named 'score', make sure it's INT(Integer) and also has a default value, '0'. Next, we would want to update that 'score' column whenever they play a mini-game so what we will do is go to the following folder: /Houdini/Houdini/Handlers/Games/ and open the __init__.py file. Well, I had to use the MYSQL module because I couldn't really understand sqlalchemy and MYSQLdb module seemed easy, so yeah. If you don't have the module, install it using the following command: pip install MySQLdb After that in the file, import this import MySQLdb after import math, time Now, we need to use the module so paste this code after the maxScorePerMinute = { array db = MySQLdb.connect(host="localhost", user="root", passwd="pass", db="houdini", autocommit=True) cur = db.cursor() Find the def handleSendGameOver(self, data): function and inside if self.server.stampGroups.isStampRoom(self.room.Id): after coinsEarned = determineCoinsEarned(self.room.Id, data.Score) add this: ID1 = self.user.ID cur.execute("UPDATE penguins SET score = score + %s WHERE ID = %s " % (data.Score, ID1)) Do the same for the next else statement: http://prntscr.com/ibb3b4 Restart Houdini, now onto the web-server part. <html> <head> <title>Leaderboard</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <center><h1>TOP 10 Score Leaderboard</h1></center> <center> <?php $db = new mysqli('localhost','root','pass','houdini'); if ($db->connect_error) { die('Error : ('. $db->connect_errno .') '. $db->connect_error); } $results = $db->query("SELECT username, score FROM penguins ORDER BY score DESC LIMIT 10"); echo "<table border='1' <tr> <th>Username</th> <th>Score</th> </tr>"; while($row = $results->fetch_array()) { echo '<tr>'; echo '<td>'.$row["username"].'</td>'; echo '<td>'.$row["score"].'</td>'; echo '</tr>'; } echo '</table>'; $db->close(); ?> </center> </body> </html> You can change the LIMIT 10 to whatever number you like. So, whenever someone plays a game their score will get updated and it will display on the leaderboard. Thanks, Dev.
