if(strcmp(cmd, "/b", true) == 0)//local ooc
    {
      if(IsPlayerConnected(playerid))
      {
        if(gPlayerLogged[playerid] == 0)
        {
          SendClientMessage(playerid, COLOR_GREY, "  You havent logged in yet !");
          return 1;
        }
            GetPlayerName(playerid, sendername, sizeof(sendername));
            new length = strlen(cmdtext);
            while ((idx < length) && (cmdtext[idx] <= ' '))
            {
                idx++;
            }
            new offset = idx;
            new result[64];
            while ((idx < length) && ((idx - offset) < (sizeof(result) - 1)))
            {
                result[idx - offset] = cmdtext[idx];
                idx++;
            }
            result[idx - offset] = EOS;
            if(!strlen(result))
            {
                SendClientMessage(playerid, COLOR_GRAD2, "USAGE: /b [local ooc chat]");
                return 1;
            }
            format(string, sizeof(string), "%s Says: (( %s ))", sendername, result);
            ProxDetector(20.0, playerid, string,COLOR_FADE1,COLOR_FADE2,COLOR_FADE3,COLOR_FADE4,COLOR_FADE5);
            printf("%s", string);
        }
        return 1;
    }
