[SRC] Adding a new Chat

[darkmeistersp]

With this modification you will have a new chat, like @main for another purposes. In this example I use @trading as an example.

1 -> Open src/map/atcommand.c and find:

 if(sd->state.mainchat)
  clif_displaymessage(fd, msg_txt(384)); // Main chat currently enabled. Usage: @main <on|off>, @main <message>.
 else
  clif_displaymessage(fd, msg_txt(385)); // Main chat currently disabled. Usage: @main <on|off>, @main <message>.
}
return 0;
}

Add below it:

/*===================================
* Trading chat chat [darkmeistersp]
* Usage: @trading <on|off|message>
*-----------------------------------*/
ACMD_FUNC(trading)
{
if( message[0] ) {
 if(strcmpi(message, "on") == 0) {
  if(!sd->state.tradingchat) {
sd->state.tradingchat = 1;
clif_displaymessage(fd, msg_txt(950)); // trading chat has been activated.
  } else {
clif_displaymessage(fd, msg_txt(951)); // trading chat already activated.
  }
 } else if(strcmpi(message, "off") == 0) {
  if(sd->state.tradingchat) {
sd->state.tradingchat = 0;
clif_displaymessage(fd, msg_txt(952)); // trading chat has been disabled.
  } else {
clif_displaymessage(fd, msg_txt(953)); // trading chat already disabled.
  }
 } else {
  if(!sd->state.tradingchat) {
sd->state.tradingchat = 1;
clif_displaymessage(fd, msg_txt(950)); // trading chat has been activated.
  }
  if (sd->sc.data[sC_NOCHAT] && sd->sc.data[sC_NOCHAT]->val1&MANNER_NOCHAT) {
clif_displaymessage(fd, msg_txt(957));
return -1;
  }
  sprintf(atcmd_output, msg_txt(956), sd->status.name, message);
  // I use 0xFE000000 color for signalizing that this message is
  // trading chat message. 0xFE000000 is invalid color, same using
  // 0xFF000000 for simple (not colored) GM messages. [LuzZza]
  intif_broadcast2(atcmd_output, strlen(atcmd_output) + 1, 0xFE000000, 0, 0, 0, 0);
 }

} else {

 if(sd->state.tradingchat)
  clif_displaymessage(fd, msg_txt(954)); // trading chat currently enabled. Usage: @trading <on|off>, @trading <message>.
 else
  clif_displaymessage(fd, msg_txt(955)); // trading chat currently disabled. Usage: @trading <on|off>, @trading <message>.
}
return 0;
}

Then you need to find this:

{ "font",			   1,1,	  atcommand_font },

And add below it:

{ "trading",			1,1,	  atcommand_trading }, //[darkmeistersp]

Save this file.

2-> Open src/map/clif.c and find:

case CHAT_MAINCHAT: //[LuzZza]
 iter = mapit_getallusers();
 while( (tsd = (TBL_PC*)mapit_next(iter)) != NULL )
 {
  if( tsd->state.mainchat && tsd->chatID == 0 && packet_db[tsd->packet_ver][RBUFW(buf,0)].len )
  { // packet must exist for the client version
WFIFOHEAD(tsd->fd, len);
memcpy(WFIFOP(tsd->fd,0), buf, len);
WFIFOSET(tsd->fd,len);
  }
 }
 mapit_free(iter);
 break;

Add below it:

case CHAT_TRADINGCHAT: //[darkmeistersp]
 iter = mapit_getallusers();
 while( (tsd = (TBL_PC*)mapit_next(iter)) != NULL )
 {
  if( tsd->state.tradingchat && tsd->chatID == 0 && packet_db[tsd->packet_ver][RBUFW(buf,0)].len )
  { // packet must exist for the client version
WFIFOHEAD(tsd->fd, len);
memcpy(WFIFOP(tsd->fd,0), buf, len);
WFIFOSET(tsd->fd,len);
  }
 }
 mapit_free(iter);
 break;

Now find this in the same file:

WBUFW(buf,0)=0x8d;
WBUFW(buf,2)=len+8;
WBUFL(buf,4)=0;
safestrncpy((char *) WBUFP(buf,8),message,len);
clif_send(buf,WBUFW(buf,2),NULL,CHAT_MAINCHAT);
}

And add below it:

/*==========================================
* Send trading chat message [darkmeistersp]
*------------------------------------------*/
void clif_TradingChatMessage(const char* message)
{
char buf[200];
int len;

if(!message)
 return;

len = strlen(message)+1;
if (len+8 > sizeof(buf)) {
 ShowDebug("clif_TradingChatMessage: Received message too long (len %d): %sn", len, message);
 len = sizeof(buf)-8;
}
WBUFW(buf,0)=0x8d;
WBUFW(buf,2)=len+8;
WBUFL(buf,4)=0;
strncpy((char *) WBUFP(buf,8),message,len);
clif_send((unsigned char *) buf,WBUFW(buf,2),NULL,CHAT_TRADINGCHAT);
}

Now find the next code:

 // Chat logging type 'M' / Main Chat
 if( log_config.chat&1 || (log_config.chat&32 && !((agit_flag || agit2_flag) && log_config.chat&64)) )
  log_chat("M", 0, sd->status.char_id, sd->status.account_id, mapindex_id2name(sd->mapindex), sd->bl.x, sd->bl.y, NULL, message);
 return;
}

And add below it:

// Trading chat [darkmeistersp]
if(strcmpi(target, trading_chat_nick) == 0)
{
 if(!sd->state.tradingchat)
  clif_displaymessage(fd, msg_txt(958)); // You should enable trading chat with "@trading on" command.
 else {
  char output[256];
  snprintf(output, ARRAYLENGTH(output), msg_txt(956), sd->status.name, message);
  intif_broadcast2(output, strlen(output) + 1, 0xFE000000, 0, 0, 0, 0);
 }
}

Save this file.

3-> Open src/map/clif.h and find this:

CHAT_MAINCHAT,  // everyone on main chat

Add below it:

CHAT_TRADINGCHAT, //[darkmeistersp]

In the same file find this line:

void clif_MainChatMessage(const char* message); //luzza

And add below it:

void clif_TradingChatMessage(const char* message); //[darkmeistersp]

Save this file.

4-> Open src/map/map.c and find this:

char main_chat_nick[16] = "Main";

Add below this:

char trading_chat_nick[16] = "Trading"; //[darkmeistersp]

In the same file find:

if(strcmpi(w1, "main_chat_nick")==0)
safestrncpy(main_chat_nick, w2, sizeof(main_chat_nick));

And add below it:

if(strcmpi(w1, "trading_chat_nick")==0) //[darkmeistersp]
safestrncpy(trading_chat_nick, w2, sizeof(trading_chat_nick));

Save this file.

5 -> Now open src/map/map.h and find:

extern char main_chat_nick[16];

Add below it:

extern char trading_chat_nick[16]; //[darkmeistersp]

Save this file

6 -> Open src/map/pc.h and find:

unsigned int mainchat :1; //[LuzZza]

And add below it:

unsigned int tradingchat :1; //[darkmeistersp]

Save this file.

7 -> Open src/char/char.c and find:

 // check for reserved names

if( strcmpi(name, main_chat_nick) == 0 || strcmpi(name, wisp_server_name) == 0 )
	return -1; // nick reserved for internal server messages

Replace it with:

// check for reserved names
if( strcmpi(name, main_chat_nick) == 0 || strcmpi(name, wisp_server_name) == 0 || strcmpi(name, trading_chat_nick) == 0) //[darkmeistersp]
return -1; // nick reserved for internal server messages

Save this file.

8-> Open src/char/inter.c and find:

char main_chat_nick[16] = "Main";

Add below it:

char trading_chat_nick[16] = "Trading"; //[darkmeistersp]

Now find this in the same file:

} else if(strcmpi(w1, "main_chat_nick")==0){ // Main chat nick [LuzZza]
safestrncpy(main_chat_nick, w2, sizeof(main_chat_nick));

And add below it:

} else if(strcmpi(w1, "trading_chat_nick")==0){ // trading chat nick [darkmeistersp]
safestrncpy(trading_chat_nick, w2, sizeof(trading_chat_nick));

Save this file.

9-> Open src/char/inter.h and find:

​extern char main_chat_nick[16];

Add below it:

extern char trading_chat_nick[16]; //[darkmeistersp]

Save this file.

10-> Repeat the steps 7, 8 and 9 with the files char.c, inter.c and inter.h that are located in src/char_sql/

11-> Open conf/msg_athena.conf and add at the end of the file:

950: Trading chat has been activated.
951: Trading chat already activated.
952: Trading chat has been disabled.
953: Trading chat already disabled.
954: Trading chat is currently enabled. Usage: @trading <on|off>, @trading <message>.
955: Trading chat is currently disabled. Usage: @trading <on|off>, @trading <message>.
956: %s :Trading: %s
957: You cannot use Trading chat while muted.
958: You should enable trading chat with "@trading on" command.

Save this file.

12 -> Open conf/inter_athena.conf and find this:

// Nick for sending mainchat
// messages like whisper
main_chat_nick: Main

Add below it:

// Nick trading chat [darkmeisterp]
sell_chat_nick: trading

Save this file.

13 -> Open conf/atcommand_athena.conf and add at the end of the file:

//Trading chat
trading: 1,1

That´s all. Now you must compile your server and your new chat is ready!

Here you have the diff for this mod. Enjoy it!

[WishBone]

Sounds interesting. Can we get screenshots or a video of how it looks like in game?

Edited November 22, 2011 by WishBone

[darkmeistersp]

Sure, I´m uploading a screenshot right now.

[gfxmrmark]

wow thanks for the share

[Judas]

wow nice!

[randell1993]

so this means anything you type will be sent as like that?

[darkmeistersp]

Yes, is the same as @main but @trading. I used this for creating a chat for selling/buying items.

[randell1993]

uhm is there a way to modify this so that only ppl with fid=1 ( sql column on login table ) can only read the msg and if they're not on the same fid they cannot use it thnx again

[darkmeistersp]

I updated the guide with one more step.

uhm is there a way to modify this so that only ppl with fid=1 ( sql column on login table ) can only read the msg and if they're not on the same fid they cannot use it thnx again

Why don´t you simply change the GM level for the command in atcommand_athena to a level you want and give this GM level to the players?

[randell1993]

lol thnx anyways ill try to figure out myself

since i need this for my faction system

This is an extraordinary feat. Is there anyway to make it display different, like...

[#Trading] - [CharName: message_here]

Good Job though !

Try changing this in msg_athena.conf:

956: %s :Trading: %s

Replace to:

956: Trading - %s : %s

[Sneaky]

Try changing this in msg_athena.conf:

956: %s :Trading: %s

Replace to:

956: Trading - %s : %s

That's not really what I meant, what I meant was that in the CHAT it appears like this:

[#Trading] - [CharName: message_here]

[#Trading] - [lolete: hi eAthena!!!]

Instead of:

lolete: Trading: hi eAthena!!!

[darkmeistersp]

You want this right?

Change the msg in msg_athena.conf

956: Trading - %s : %s

for

956: [#Trading] - [%s: %s]

[Sneaky]

That's what I meant, thanks a lot, will definitely be using this feat.

[jTynne]

VERY awesome modification! Thanks for releasing this to the public!

[darkmeistersp]

*UPDATED: I´ve added the diff for the mod. Enjoy it!

[Mystery]

Hm, very cool mod. I'll be using this in the future. Thanks for the release ;D

[Diconfrost VaNz]

i love this mod...

how can i put some delay on it?

for example, before you can use it you must wait for 1minute just like a broadcaster(just for anti-flooding purposes)

[KeiKun]

@ TS

nice released

already tried

once i thought another Snippet with No diff file

since i hate manually adding~

[jTynne]

This would be a wonderful addition to the emulator as many servers that I've played recently have opted to go this route. Five stars for this mate!

[Sneaky]

Actually I just tested this yesterday and turned out that I had to turn @main on first in order to use @trading. Not sure if you guys are getting the same problem. I even checked the codes 3 times, everything seem'd to be fine.

[jTynne]

Hmm, yeah, I see I'm also having the same issue. Are you able to PM "Trading", as I'm unable to do so. That'd be a nice addition to this. Messages to @trading are displaying on @main for whatever reason. No compilation errors, however.

[darkmeistersp]

I´m going to revise the code.

[Mirage]

Love it!!

Question...

Would the code stop working if I replace the "trade" related works with "market" ?

..or am I not allowed to revise the code
