Hello.

The objective is to write a command for this stuff in the title using sscanf.
Command: /id [name/part]
I found some tutorial in sscanf topic and I really didn't understood how this method works (and whether works).

Could anybody explain me how to make it and how it works?

Thanks.

Why explain? Its specifier . It work like this: If you enter /id John and If there is only one with strating name John it will select him if there are more with starting name John then it will select nothing :P. http://prntscr.com/b7tx8h

    if(sscanf(params, "s[24]", name)) return SendClientMessage(playerid, GREY, "Usage: /id [player name or part of name]");
    format(string, sizeof(string), "%s\n%s - ID %d", string, RemoveUnderScore(GetPlayerID(name, 1)), GetPlayerID(name, 1));
	SendClientMessage(playerid, WHITE, string);
    return 1;
}

Basically, if an array of size "N" is passed, this code will return the first N-1 results. If there are less than "N" players whose name matches the given name then that many players will be returned and the next slot will be "INVALID_PLAYER_ID" to indicate the end of the list. On the other hand if there are MORE than "N - 1" players whose name matches the given pattern, then the last slot will be "cellmin" to indicate this fact. When combined with "U" and returning the default, the first slot is always exactly the default value (even if that's not a valid connected player) and the next slot is always "INVALID_PLAYER_ID". Note also that user arrays can't be combined with normal arrays or enums, but normal single-return user specifiers still can be.

I didn't understood how to find a player with 'u' specifier.

Код:

new ids[3], i;
if (sscanf("Le", "?<MATCH_NAME_PARTIAL=1>u[3]", ids)) printf("Error in input");
for (i = 0; ids[i] != INVALID_PLAYER_ID; ++i)
{
    if (ids[i] == cellmin)
    {
        printf("Too many matches");
        break;
    }
    printf("id = %d", ids[i]);
}
if (i == 0) printf("No matching players found.");

The loop looks very strange for me.

		 format(szMessage, 64, "%i. %s - %i", index + 1, Players[index][m_szName], arrPlayers[index]);
		SendClientMessage(playerid, -1, szMessage);
	}

	if(index == 0)
	{
		SendClientMessage(playerid, C_DUMMY, "Совпадений не найдено");
		return true;
	}

	if(bTooMany == 1)
	{
		SendClientMessage(playerid, C_DUMMY, "Показано 7 первых найденых игроков");
		return true;
	}

	return true;
}

This should work?

Dont use like that

I prefer this:

PHP код:

new ids, i;
if (sscanf("Le", "r", ids)) print("Error in input"); //what is Le?
//check if player is connected
if(!IsPlayerConnected(ids)) return print("Player is not connected'); 
printf("id = %d", ids); 


If you want for all players with that starting name use strcmp

Tested this. Perhaps works fine. Thanks all.

In format, you have:

pawn Код:

Players[index][m_szName]

It should be:

pawn Код:

Players[arrPlayers[index]][m_szName]
