How to use zcmd without sscanf -
CrazyLess - 03.10.2011
I was wondering if it's possible to make commands in zcmd without sscanf since it's not fixed yet. So I was actually trying to make a command like this
getinfo name password
Here i went so far
pawn Код:
COMMAND:getinfo(playerid, params[])
{
new Query[256], DBResult:Result;
if(sscanf(params, "dz", oname, )) return SendClientMessage(playerid, red, "/getinfo [playername] [password]");
format(Query, sizeof(Query), "SELECT `NAME` FROM `USERS` WHERE `NAME` = '%s' AND `PASSWORD` = '%s'", DB_Escape(params[0]), DB_Escape(params[1]));
Result = db_query(sDatabase, Query);
if(db_num_rows(Result))
{
//Show stats
}
else
{
SendClientMessage(playerid, "Password does not much or invalid name.");
}
db_free_result(Result);
return 1;
}
The password is from users account

Use
strtok

By the way, don't use 'z' use 's'.

sscanf2 is the best and fatest one, so if you will change it, you will just waste memory..

well there is a way.... STRTOK !!!!
sscanf is working fine with current samp version's (dont know about 0.3d - Its not out yet its just RC)
Well its possible to use zcmd without sscanf why not?
Maybe using old sscanf (as stock in pawn)

/*----------------------------------------------------------------------------*-
Function:
sscanf
Params:
string[] - String to extract parameters from.
format[] - Parameter types to get.
{Float,_}:... - Data return variables.
Return:
0 - Successful, not 0 - fail.
Notes:
A fail is either insufficient variables to store the data or insufficient
data for the format string - excess data is disgarded.
A string in the middle of the input data is extracted as a single word, a
string at the end of the data collects all remaining text.
The format codes are:
c - A character.
d, i - An integer.
h, x - A hex number (e.g. a colour).
f - A float.
s - A string.
z - An optional string.
pX - An additional delimiter where X is another character.
'' - Encloses a litteral string to locate.
u - User, takes a name, part of a name or an id and returns the id if they're connected.
Now has IsNumeric integrated into the code.
Added additional delimiters in the form of all whitespace and an
optioanlly specified one in the format string.

The question is "Why wouldn't you use sscanf with ZCMD?". It's easy and less complicated
