Kepler - Java v14+ server (SnowStorm, BattleBall, Camera, Wobble Squabble)

[eJustin]

The sprite id column isn't used by the server. I converted one of my private projects' catalogue for Kepler and I accidentally left the sprite id column in there.

Haven't had any luck getting this done. Are you able to point me in the right direction? Quite rusty with this stuff and need DJ Decks for some stacking nostalgia.

As I said, don't worry about the sprite_id column, put any value you want in there it's not used by the server or client.

I originally asked for help in my post but I managed to set it up myself.

[Jiyorude]

Some furni seems to be missing from the hotel, such as Habbowood, Habboween, Easter, Valentine, Christmas. Is there a way how I can download them and place them in my hotel?

[Quackster]

No one's made another catalogue for Kepler. You'll have to add them yourself using the catalogue_pages, catalogue_items and items_definitions tables.

[Quackster]

I'm going to release Kepler with a single fix (items not being unregistered when moving) but would you also like me to release Kepler with SnowStorm included inside of it too? That's the surprise I promised but initially hesitated to release it.

[webbanditten]

That would be an amazing Christmas present for the community. I would love for you to release Snowstorm.

[Quackster]

Happy New Year, Merry Christmas, Saturnalia, Yule etc.

I hope that this release brings many people joy, to make up for what a horrible year that 2020 has been.

Changelog

- Add: SnowStorm! All maps have been added along with all features. Please read README_SnowStorm.txt to get SnowStorm working correctly.
- Fix: Moving furniture properly unregisters it from its previous spot.
- Fix: Game history will show the last 15 games played, instead of expiring them after 10 minutes.

Please make sure to run the v1.3 migration SQL to enable SnowStorm from inside the server.

Huge thanks to Sefhriloff for figuring out the SnowStorm checksum override to make SnowStorm a possibility.

Yesterday I merged your branch into mine and I just want to report back that its works and I couldnt be happier.

I also want thank you for your contributions to the Habbo Retro community this year, its been truly an amazing year and your contributions arent going unnoticed.

I personally hope the community next year will show a more collaborative and supportive spirit so we can continue the retro journey together. Together as a community we can achieve much more.

A small little update to Kepler.

I've finished the RCON system so I've completely removed the old system and added a new system, included a PHP example of how to send RCON commands to Kepler too.

Changelog

- Added: New RCON system
- Removed old unused libraries which cut down the compiled size of Kepler by 6 megabytes.

Reminder! Do not make RCON listen on anything other than localhost/127.0.01, if you are please make sure you know what you're doing by exposing the RCON port to the outside world. RCON is not the same as the MUS connection which Kepler also uses.

Download: https://github.com/Quackster/Kepler/releases/tag/v1.31

PHP code example for sending RCON commands alongside their valid usages:

<?php

sendRcon("127.0.0.1", "12309", build("hotel_alert", array(
   "message" => "Hello, World!",
   "sender" => "Alex"
)));

sendRcon("127.0.0.1", "12309", build("hotel_alert", array(
   "message" => "Hello, World!"
)));

sendRcon("127.0.0.1", "12309", build("refresh_looks", array(
   "userId" => "1"
)));

sendRcon("127.0.0.1", "12309", build("refresh_hand", array(
   "userId" => "1"
)));

sendRcon("127.0.0.1", "12309", build("refresh_club", array(
   "userId" => "1"
)));

sendRcon("127.0.0.1", "12309", build("refresh_credits", array(
   "userId" => "1"
)));

function build($header, $parameters) {
  $message = "";
  $message .= pack('N', strlen($header));
  $message .= $header;
  $message .= pack('N', count($parameters));
  
  foreach ($parameters as $key => $value) {
    $message .= pack('N', strlen($key));
    $message .= $key;
 
    $message .= pack('N', strlen($value));
    $message .= $value;
  }
   
  $buffer = "";
  $buffer .= pack('N', strlen($message));
  $buffer .= $message;
  return $buffer;
}

function sendRcon($ip, $port, $command) {
    $socket = socket_create(AF_INET, SOCK_STREAM, getprotobyname('tcp'));
    socket_connect($socket, $ip, $port);
    socket_send($socket, $command, strlen($command), MSG_DONTROUTE);    
    socket_close($socket);
} 

?>

Java example:

public class RconCommand {
    private final RconHeader header;
    private final Map<String, Object> parameters;

    public RconCommand(RconHeader header, Map<String, Object> parameters) {
        this.header = header;
        this.parameters = parameters;
    }
    
    public void send() {
        try (Socket socket = new Socket(ServerConfiguration.getString("rcon.ip"), ServerConfiguration.getInteger("rcon.port"))) {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            DataOutputStream daos = new DataOutputStream(baos);

            daos.writeInt(header.getRawHeader().length());
            daos.write(header.getRawHeader().getBytes(StringUtil.getCharset()));
            daos.writeInt(parameters.size());

            for (var entry : parameters.entrySet()) {
                daos.writeInt(entry.getKey().length());
                daos.write(entry.getKey().getBytes(StringUtil.getCharset()));

                daos.writeInt(entry.getValue().toString().length());
                daos.write(entry.getValue().toString().getBytes(StringUtil.getCharset()));
            }

            try (DataOutputStream dataOutputStream = new DataOutputStream(socket.getOutputStream())) {
                byte[] message = baos.toByteArray();

                dataOutputStream.writeInt(message.length);
                dataOutputStream.write(message);
                dataOutputStream.flush();

                baos.close();
                daos.close();
                socket.close();
            } catch (IOException ignored) {

            }
        } catch (IOException ignored) {

        }
    }
}

I'm so glad it worked out well and I agree completely.

Hi there!
First, thank you for your hard work @Quackster, the result really looks nice ! :)
Though, I'm having an issue connecting to the server from the client..

I'm starting the server from the BAT file, and connecting to localhost using the Basilisk browser (Shockwave is working on some online demos).
I've also ran the SQL file into MySQL.

The issue is when trying to connect with Basilisk, I'm getting the result below when trying to connect (takes a long minute of loading before displaying that):


No error in the server command line but I see a connection attempt (screenshot below).



Thank you for your help!

Okay you are like the tenth person to try and load the Habbo TCP port in the browser, are you all the same person?

You have to use a loader with DCRS on an HTML file that connects to the server. I'm fed up with being asked the same question over the span of a year or more.

Omg, finally thank you Alex! <3

Add a webserver to Kepler that runs the client. Problem solved /s

Thank you guys, didn't find this info anywhere before
Sorry for the bother @Quackster ..
