Can anyone tell me how to make one?

1. if you use sscanf, use "u" parameter.
2. Use the ReturnUser() function:

pawn Код:

IsNumeric(const string[])
{
    for (new i = 0, j = strlen(string); i < j; i++)
    {
        if (string[i] > '9' || string[i] < '0') return 0;
    }
    return 1;
}

ReturnUser(text[], playerid = INVALID_PLAYER_ID)
{
    new pos = 0;
    while (text[pos] < 0x21) // Strip out leading spaces
    {
        if (text[pos] == 0) return INVALID_PLAYER_ID; // No passed text
        pos++;
    }
    new userid = INVALID_PLAYER_ID;
    if (IsNumeric(text[pos])) // Check whole passed string
    {
        // If they have a numeric name you have a problem (although names are checked on id failure)
        userid = strval(text[pos]);
        if (userid >=0 && userid < MAX_PLAYERS)
        {
            if(!IsPlayerConnected(userid))
            {
                /*if (playerid != INVALID_PLAYER_ID)
                {
                    SendClientMessage(playerid, 0xFF0000AA, "User not connected");
                }*/
                userid = INVALID_PLAYER_ID;
            }
            else
            {
                return userid; // A player was found
            }
        }
        /*else
        {
            if (playerid != INVALID_PLAYER_ID)
            {
                SendClientMessage(playerid, 0xFF0000AA, "Invalid user ID");
            }
            userid = INVALID_PLAYER_ID;
        }
        return userid;*/
        // Removed for fallthrough code
    }
    // They entered [part of] a name or the id search failed (check names just incase)
    new len = strlen(text[pos]);
    new count = 0;
    new name[MAX_PLAYER_NAME];
    for (new i = 0; i < MAX_PLAYERS; i++)
    {
        if (IsPlayerConnected(i))
        {
            GetPlayerName(i, name, sizeof (name));
            if (strcmp(name, text[pos], true, len) == 0) // Check segment of name
            {
                if (len == strlen(name)) // Exact match
                {
                    return i; // Return the exact player on an exact match
                    // Otherwise if there are two players:
                    // Me and MeYou any time you entered Me it would find both
                    // And never be able to return just Me's id
                }
                else // Partial match
                {
                    count++;
                    userid = i;
                }
            }
        }
    }
    if (count != 1)
    {
        if (playerid != INVALID_PLAYER_ID)
        {
            if (count)
            {
                SendClientMessage(playerid, 0xFF0000AA, "Multiple users found, please narrow earch");
            }
            else
            {
                SendClientMessage(playerid, 0xFF0000AA, "No matching user found");
            }
        }
        userid = INVALID_PLAYER_ID;
    }
    return userid; // INVALID_USER_ID for bad return
}
