NexusServer v2 Current version: v2.0.0 r169 (SVN only)
A Habbo Hotel server core written in C++ using the Qt Framework.
Supported protocols: (Untested versions followed by a question mark, but are assumed to work)
Shockwave: v8? v9 v10? v11? v12? v13 v14 v15 v16 v17? v18? v19?
Hello everyone, some of you may remember NexusServer, a project Ktae and I worked on in June-ish. Our servers are back up, and I've decided that though this isn't a project I can profit from (or even put into something like my portfolio,) I'd really like to finish it. A Few days ago Ktae wrote a nice socket/thread pooling/queue system, so using it I've decided to restart NexusServer. Most of the old code was hackish/stubs so I'll be starting pretty much from scratch.
Server specific features:
Code:
- C++ (Qt, multiplatform)
- Thread pooling system (currently in need of a few fixes)
- Thread safe packet broadcasting using Qt's Signal/Slot system
- QSql (Compatible with a wide array of drivers, from SQLite to MySQL to ODBC
- Optional native unix-like terminal implementation for windows and curses support
where applicable (incomplete)
- INI-style configuration
- language binding support
Currently implemented (but most likely incomplete) features:
Code:
- encoding (VL64/B64)
- non-sso login
- non-sso registration
- updating figure/motto/etc
- public room list (stub)
- private room categories
- room creation (the client does this improperly)
- room listing (complete)
- own room listing (complete)
- entering rooms
- room user listing (incomplete)
- chat
- temporary warping until pathfinding
- catalog
- hand (perfect)
- furniture (under dev)
- posters
- spaces (wallpaper/floor)
- console missions
- searching for users in the console
- friend requests (partial)
- messages (partial)
- public rooms (partial, currently only in the navigator)

Example of an implemented packet with the packet builder (private room category listing, incomplete but commented):
PHP Code:
--- at the beginning --- int showfull = pak.readVL64(); int cat = pak.readVL64();
--- case 4 (private rooms root)? in the switch(cat) statement --- query.prepare("SELECT id, title FROM roomcategories"); if(query.exec()){ Packet npak("C\\"); npak += showfull; npak += cat; npak += false; //? npak += "Guest Rooms"; npak += 0;// current users npak += 0;// max users npak += 1;// parent id (should this be cat?) //npak += 4;// rooms count while (query.next()) { npak += query.value(0).toInt(); npak += 2; //? npak += query.value(1).toString(); npak += 0;//current visitors npak += 0;//max visitors npak += cat; npak += false; //? } client->sendPacket(npak); } break;
--- another packet, full this time --- case Opcode::RequestEnterRoom: { if(client->isInRoom)client->inRoom->removeClient(client); // remove the client from the current room client->inRoom = Room::getRoom(pak.buffer.mid(pak.position,pak.buffer.length() - 5).toInt()); // D: plain text int client->inRoom->addClient(client); if(client->isInRoom){ Packet npak("@v"); npak += false; //? npak += false; //? npak += client->inRoom->id; npak += client->inRoom->ownerstr; npak += client->inRoom->model; npak += client->inRoom->title; npak += client->inRoom->description; npak += true; //show owner npak += true; //? npak += false; //? npak += 0; //current users npak += 25; //max users client->sendPacket(npak); npak = Packet("Eb"); npak += 0;// category, nyi client->sendPacket(npak); }else{ //client->writeData("BKRoom not found!\001"); Packet err("BK"); err.appendRawLangString("error.room_not_found"); client->sendPacket(err); } break; }
Also, some of the packets require slightly different handling, the packet system also supports methods for those, here is an example of that:
PHP Code:
case Opcode::RequestUserList: { Packet pae("@\\");
The latest code for the implementations of packets should always be available here aswell.
Possible future features/ideas:
Code:
- Remote control panel (desktop/possibly mobile)
- Server is set up to easily implement multiprotocol support in the future
- Javascript module system for easy server expansion
Known issues:
Code:
- Clients are not deleted quite properly yet, they can sometimes lead to a small (but not continuous) memory leak
This should be fixed once someone gets the time
- Poor error handling, sometimes a broken task can crash the server.
- A few packets are const char* stubs, and need to be updated, they include (server->client header):
- DU // encryption? thanks lab-hotel
- DA //date string/session variables?
- DZ //unknown registration
- DO //unknown registration
- CY //unknown registration
- Dt //?
- Dp //?
- Dy //?
- Dz //?
- DB //room load advertisement
- CP //unknown?
- @^ //unknown room related?
- @G // subscription information (stub)
- "Yay! It's being delivered now." message appears when the client sends AXCarryItem or whatever,
That packet is still unhandled so the client seems to be doing this all on it's own, maybe I need
to tell it NOT to do that?
- Some rugs are broken, the produce a PH box, this shouldn't be too hard to fix
- Sometimes the hand doesn't update when you place an item down so it stays in your hand,
it'l go away if you re-open the hand or put it down though, this shouldn't be too hard to fix
either. (items arent being duplicated, the client just isnt being updated correctly, this has been improved)
- If the server is spammed with an impossible amount of packets, the task system can break, a fix is currently in the works.
- The thread pool system is in need of some fixes (not hard ones though), some also pertaining to the above issue.
Here is a recent youtube video demonstrating the functionality of the server: (severely outdated) ( new video coming soon )Furniture, a taste of multiplatform
And here are the old videos, more will be placed here as they become outdated:
Setting up Qt Creator on Linux: (Not universal, but you should be able to extrapolate)
-Download and install the package build-essential (GCC) (usually apt-get install build-essential)
-Download and install the following libraries:
-libglib2.0
-libSM
-libxrender
-libfontconfig
-libxext
(For debian and Ubuntu the command to do this is: sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev)
-Download the Qt SDK from here.
-Make the downloaded installer executable (chmod +x filename.bin)
-Run the installer (./filename.bin)
Setting up Qt Creator on Mac:
-Register as a developer on apple's website to download XCode (or find a mirror)
-install XCode (with the GNU C bindings, there should be a checkbox in the installer)
-Download and install the Qt SDK (online installer, or offline) from here.
Checking out and compiling NexusServer2:
-Install an SVN Client (apt-get isntall svn on linux, it comes with XCode on Mac, and I'd recommend TortoiseSVN for windows.)
-Create a new folder for the NexusServer2 source.
-Check out the svn http://svn.nexustools.net/nexusserver2/trunk/ (svn co <url> for Linux and Mac, right click the folder and click "SVN Checkout..." for TortoiseSVN (windows))
-Open the .pro file you just checked out in QtCreator, you should be ready to compile!
This project is far from complete, I expect it to be updated often.
We're looking for any help we can get on this project, that includes suggestions, so if you think you have something to contribute feel free to PM me or post here.

Your first server was awesome, good to see your back ^^
PHP Code:
static string Encode_VL64(int i){
string s = "";
char res[6]; //assign the var res to a a char array - len6
int p = 0; int sP = 0;
int bytes = 1;
int negativeMask = i >= 0 ? 0 : 4; //? : = if else clause
i = abs(i);
res[p++] = (char)(64 +(i & 3));
for (i >>= 2; i != 0; i >>= 6){
bytes++;
res[p++] = (char)(64 + (i & 0x3f));
}
int null = 0;
res[sP] = (char)(res[sP] | bytes << 3 | negativeMask);
string tmp = string(res);
tmp.erase(2,22);
return tmp;
}
static string Encode_B64(int i){
string s = "";
for (int x = 1; x <= 2; x++){
s += (char)((char)(64 + (i >> 6 * (2 - x) & 0x3f)));
}
return s;
}
static int Decode_B64(string strVal){
int intTot = 0;
int y = 0;
for (int x = (strVal.length() - 1); x >= 0; x--) {
int intTmp = (int) (char) ((strVal.at(x) - 64));
if (y > 0) {
intTmp = intTmp * pow(64.0, y);
}
intTot += intTmp;
y++;
}
return intTot;
}
static int Decode_VL64(string raw){
int pos = 0;
int v = 0;
bool negative = (raw[pos] & 4) == 4;
int totalBytes = raw[pos] >> 3 & 7;
v = raw[pos] & 3;
pos++;
int shiftAmount = 2;

{
v |= (raw[pos] & 0x3f) << shiftAmount;
shiftAmount = 2 + 6 * b;
pos++;
}
if (negative)
v *= -1;
return v;

I ported the vl64 and b64 stuff that Jeax wrote, if you need it
Good luck with this :D Posted via Mobile Device

Thanks :) yeah, the things that are static aren't that important to the function yet. (Except that outfit pieces one, I need to find a proper list of the club vs free outfit configurations.) Apparently sending fuse_use_club_outfits doesn't do anything.
@Caustik, Thanks :o but I was able to move the old encoding methods over from the other server and improve them a little, so that's already covered.
Happy new years everyone :)
Edit: The changelog has been updated. I implemented listing your own rooms, and started implementing entering rooms.

Why are you using string's instead of byte arrays, your causing pointless overhead.
