{
  unsigned int i;
  t_message *  message;

  for (i=0; text[i]!=' ' && text[i]!='\0'; i++); /* skip command */
  for (; text[i]==' '; i++);

  if (text[i]=='\0')
  {
    message_send_text(c,message_type_info,c,"usage: /announce <announcement>");
    return 0;
  }

  snprintf(msgtemp, sizeof(msgtemp), "Announcement from %.14 %.64s: %.128s",account_get_grade(account),conn_get_username(c),&text[i]);
  if (!(message = message_create(message_type_broadcast,c,msgtemp)))
    message_send_text(c,message_type_info,c,"Could not broadcast message.");
  else
    {
      if (message_send_all(message)<0)
    message_send_text(c,message_type_info,c,"Could not broadcast message.");

Re: how to make ann

First you have to get account from the current connection.

Example: https://github.com/HarpyWar/pvpgn/blob/ … d.cpp#L559

t_account * account;

  if (!(account  = conn_get_account(c))){
      ERROR0("got NULL account");
  }

Re: how to make ann

I'm sorry i don't know what do you mean
do you mean like this?

static int _handle_announce_command(t_connection * c, char const *text)
{
  unsigned int i;
  t_message *  message;
  t_account * acc;

  if (!(acc = account_get_grade(c))){
      ERROR0("got NULL account");
  }

  for (i=0; text[i]!=' ' && text[i]!='\0'; i++); /* skip command */
  for (; text[i]==' '; i++);

  if (text[i]=='\0')
  {
    message_send_text(c,message_type_info,c,"usage: /announce <announcement>");
    return 0;
  }

  snprintf(msgtemp, sizeof(msgtemp), "Announcement from %.14 %.64s: %.128s",account_get_grade(c),conn_get_username(c),&text[i]);
  if (!(message = message_create(message_type_broadcast,c,msgtemp)))
    message_send_text(c,message_type_info,c,"Could not broadcast message.");
  else
    {
      if (message_send_all(message)<0)
    message_send_text(c,message_type_info,c,"Could not broadcast message.");
      message_destroy(message);
    }

  return 0;
}

but when i try this code
i found error

17>..\..\..\source\src\bnetd\command.cpp(776): warning C4146: unary minus operator applied to unsigned type, result still unsigned
17>..\..\..\source\src\bnetd\command.cpp(1736): warning C4101: 'i' : unreferenced local variable

Why did you do this? I have given you an example.

Look at the error "cannot convert parameter 1 from 'pvpgn::bnetd::t_connection *' to 'pvpgn::bnetd::t_account".
It means that function account_get_grade takes argument type of t_account, but you invoke it with argument type of t_connection ("c").

Please, learn basics of c++ before making suchlike source modifications.
