One char per gm account

[Svanhild 2]

I use to have this feature in rathena, but I lost and forgot the source mod for this. So I'm requesting another one.

simple patch plugin

#include "common/hercules.h"#include <stdio.h>#include <string.h>#include <stdlib.h>#include "char/char.h"#include "common/nullpo.h"#include "common/HPMDataCheck.h"HPExport struct hplugin_info pinfo = {	"1charpergm", // Plugin name	SERVER_TYPE_CHAR,// Which server types this plugin works with?	"0.1",			// Plugin version	HPM_VERSION,	// HPM Version (don't change, macro is automatically updated)};int char_make_new_char_sql_pre(struct char_session_data* sd, char* name_, int str, int agi, int vit, int int_, int dex, int luk, int slot, int hair_color, int hair_style) {	nullpo_retr(-2, sd);	if ( slot != 0 && sd->group_id > 10 ) { // change 10 to minimum gm level		hookStop();		return -2;	}	return 0;}HPExport void plugin_init (void) {	addHookPre( "chr->make_new_char_sql", char_make_new_char_sql_pre );}

EDIT : change 'char->' into 'chr->'

now it works

 

EDIT2: what have I done LOL

forgot to add slot variable

Check what I did here on char.c

 

if( sd->group_id > 0 && sd->group_id < 99 ) {		if( SQL_ERROR == SQL->Query(inter->sql_handle, "SELECT 1 FROM `%s` WHERE `account_id` = '%d'", char_db, sd->account_id) )			Sql_ShowDebug(inter->sql_handle);		if( SQL->NumRows(inter->sql_handle) >= 1 )			return -2; // character account limit exceeded	}// check char slot    if( sd->found_char[slot] != -1 )        return -2; /* character account limit exceeded */

nonono ... the char_make_new_char_sql function already has a slot variable

so we can make use of that variable for not using sql syntax

 

btw, my mistake for not using slot variable in my previous post, fixed

somehow I'm unable to write the char_parse_char_select as plugin ...

I always get error for this line in plugin

int slot = RFIFOB(fd,2);

yeah, I noticed that and re-written the code earlier and it went fine, but I'll be using your code instead, I trust you for creating reliable codes. Thanks, Annie.

 

EDIT: Tested and it worked.

the reason for the patch is because this was requested from rAthena forum

Sorry for necroing, but can this work as plug in on most recent?
