PRELIMINARY - - - - - - - - 05/03/2004
Protocol version 4
But 0x04 will be its version for inter-protocol purposes.
This protocol is only intended to replace current protocol. Because current protocol
not expanable
SMLAN PROTCOL TCP/8765
Protcol is entirelly packaged in EzSockets Data Packets (use send and receive packet)
This will prevent any out-of-sync errors with future or past versions.
The protocol is impervious to fragmented, or bonded TCP packets.
Basic Representation:
Octet 0123 4 5
+----+-+---//--+
|ssss|C|Payload|
+----+-+---//--+
ssss - size of packet, handled by ezsockets (if you're using C++)
C - Command.
Payload - variable size based on command
The payload may contain more data than expected, i.e. new protocol version.
In the following protocol, the term size means the size of the chunk of data.
If the "size" is "NT" then that means it's a null-terminating string.
"MSN" most significant 4 bits (byte/16)
"LSN" least significant 4 bits (byte%16)
Note: Primary player is 0x0, secondary player is 0x1

A re-writing of the SMLan Protocol, because I wish to understand it in
my own words. -aj
Protocol version: 0x04 (v4)
This has nothing to do with the server versions (see below)
==Client Versions==
(NETPROTOCOLVERSION in NetworkSyncManager.h)
1: StepMania 3.9 (SMLan?)
2: StepMania 3.95
3: StepMania 4 alphas, sm-ssc v1.0-v1.2.5, StepMania 5
==Server Versions==
1: SMLan (old)
128: SMOnline
129: SMOnline with "better song identification using chart hashes"
==Notes==
I use the term "client" and "player" interchangeably.
The original document used "client" and "user" interchangeably.
These two notes are from the SMOCaml project:
https://sourceforge.net/projects/smocaml/
Command S2C 004 (132): The data from miss to marvelous are reversed
Commands C2S 012-001 and 012-001: when there is no password the 'password' field
isn't sended at all, not even a NULL character
==Information==
The default port is 8765/tcp, though this is actually assigned to Ultraseek HTTP
by the IANA (see http://www.iana.org/assignments/port-numbers).
A modern/official online server for StepMania will use the currently unassigned
port 48040/tcp (and/or udp if the need arises). (Port number subject to change.)
The protocol is packaged in "EzSockets Data Packets".
A basic representation
0123 4 5...... [Octets]
+----+-+---//--+
|ssss|C|Payload| [data]
+----+-+---//--+
where:
ssss = Size of packet (handled by EzSockets if using C++)
C = Command
Payload = (variable size based on command)
The payload may contain more data than expected, for instance, if it's a new
protocol version.
"Size" refers to the size of the data chunk.
Some commonly referred to size types:
NT = Null-terminated string
MSN = Most significant 4 bits (byte/16)
LSN = Least significant 4 bits (byte%16)
The primary player is 0x0, secondary is 0x1. This does not take into account
Multiplayer notefields.
==[ Client -> Server Communication Protocol ]===================================
0x00 (000) No Operation
This command will case the server to respond with a nop.
Payload: None
Expected response: Server 0x01 (001)
________________________________________________________________________________
0x01 (001) No Operation Response

MSN Start Position:
0 = pre-sync
1 = sync
LSN Reserved

NT Course Title (null if doesn't exist)

0x04 (004) Game Over Notice
Sent when end of game is encountered. I think technically this is round over.
Payload: None
Expected response: None (though later in the document you'd assume Server 0x04)
________________________________________________________________________________
0x05 (005) Game Status Update
The payload changes between protocols, and it will likely have to change again
to account for some more StepIDs.

1 = Miss
2 = W5
3 = W4
4 = W3
5 = W2
6 = W1
7 = LetGo
8 = Held
MSN Projected Grade (StepMania enum int, which can cause problems with themes.)

0x02 Combo (net-order int; songs with large combos may cause issues?)
0x02 Health (net-order int)
0x02 Offset (net-order number. huh)
32767 would be DEAD on the note
If the user is hitting late, the # will be higher.
It if the user is exactly 0.25 seconds off, the number will be
different by 500. With this pattern 0.5 seconds gives a difference of 1000.
Expected response: None

[How to Use EzSockets by freem]
Hey there. ezsockets is the socket library used in StepMania. If you are going to
develop any extended network functionality, it would be good to know about
ezsockets. This is by no means an exhaustive guide, as it just covers what's
contained in the header, as well as what that code does.
Section 1: low level commands===================================================
These are typically used for connecting to the server, according to a cursory
glance at ScreenPackages code.
=="Crating" a socket== (lol typos in the comments)
There are three functions here, each with different arguments (yay overloading).
All of them return a bool.
bool create(int Protocol, int Type);
This shows what's needed to make a socket. Consult the internet for complete
documentation as to possible values, but here are some ones to know:
[Protocol]
TCP = IPPROTO_TCP
UDP = IPPROTO_UDP
Raw sockets = IPPROTO_RAW (though "Protocol" is used in the code. Raw sockets
are not supported on Xbox)
bool create();
Creates a socket using (IPPROTO_TCP, SOCK_STREAM) as the parameters.
bool create(int Protocol);
This picks the right Type for you based on what Protocol you choose.
TCP uses SOCK_STREAM, UDP uses SOCK_DGRAM for the Type value.
==Binding Sockets to a Local Port==
bool bind(unsigned short port);
==Listening==
bool listen()
==Accepting==
bool accept(EzSockets &socket);
If it's not blocking and you can't read it, this will return false.
Other than that... ??
==Connecting to Server==
bool connect(const string& host, unsigned short port);
Connects to the server at host using port.
==Closing/Killing Sockets==
void close();
Sets the state to disconnected, sets the buffers to empty strings,
then closes the socket.
==Checking Socket Status==
bool check();
"see if socket has been created". It checks (sock != INVALID_SOCKET) on the
Xbox and (sock > SOCKET_NONE) on every other platform.
bool CanRead();
Returns true if you can read from the socket.
bool DataAvailable() { return ( ( inBuffer.length()>0 ) || CanRead() ); }
Yeah that's it in a nutshell. If the input buffer has data or you can read,
there's data available.
bool IsError();
Returns true if there's an error.
bool CanWrite();
Returns true if you can write to the socket.
==???==
long uAddr();
void update();
Section 2: Higher Level Commands================================================
These are higher level, since they assume you've already gotten the socket up
and running (see check() in Section 1).
//Raw data system
void SendData(const string& outData);
void SendData(const char *data, unsigned int bytes);
Send off some data that's either a string or a char buffer + num bytes.
int ReadData(char *data, unsigned int bytes);
Reads data, returns number of bytes read.
int PeekData(char *data, unsigned int bytes);
Peeks at the data, returns number of bytes read.
//Packet system (for structures and classes)
void SendPack(const char *data, unsigned int bytes);
int ReadPack(char *data, unsigned int max);
int PeekPack(char *data, unsigned int max);
Similar to the raw data system above, but... you guessed it, for structures and classes.
//String (Flash) system / Null-terminated strings
void SendStr(const string& data, char delim = '\0');
int ReadStr(string& data, char delim = '\0');
int PeekStr(string& data, char delim = '\0');
Similar to above, with null terminated strings.
Section 3: putting it all together==============================================
okay i didn't test this; this is based on ScreenPackages code (specifically
ScreenPackages::EnterURL()), which assumes you have a private EzSockets object
named m_wSocket.
{
// defaults
RString sProto;
RString sServer;
int iPort=80;
RString sAddress;
m_wSocket.create(); // will create a TCP socket
m_wSocket.blocking = true; // you want to set this so that nothing else can use this socket and fuck things up
m_wSocket.connect( sServer, (short)iPort ); // connect uses an unsigned short, so a cast is needed. (int was used because of other code) check if this returns true/false, pls
// makin' headers (using SendData with raw data; http 1.0 in this case)
RString Header="";
Header = "GET "+sAddress+" HTTP/1.0\r\n";
Header+= "Host: " + Server + "\r\n";
Header+= "Connection: closed\r\n\r\n";
m_wSocket.SendData( Header.c_str(), Header.length() );
m_wSocket.blocking = false; // once you're done, you don't need to have the socket blocking anymore
// some other code can go here...
m_wSocket.close(); // and if you're done, you can close the socket.
}
