[Pawn] how to get the last digit of a player's IP

[Kwarde]

Easiest (and, afaik the best) way would be with sscanf:

Code:

new
    ip[] = "192.168.2.10";
    ip_part1,
    ip_part2,
    ip_part3,
    ip_part4
;
sscanf(ip, "p<.>dddd", ip_part1, ip_part2, ip_part3, ip_part4);
//OR, if you (as the title suggests) really just want the last part:
sscanf(ip, "p<.>{ddd}d", ip_part4);

//ip_part1 = 192
//ip_part2 = 168
//ip_part3 = 2
//ip_part4 = 10

I read your post after placing this.. (I did quickly go over it but didn't really read it, oops) how does strfind() not work for you? It either returns -1 (string you're looking for not found), or it returns the first character of the found string (or according to the wiki: "The number of characters before the sub string (the sub string's start position) ", so basically the same thing)

Code:

new ip[] = "192.168.1.200";
if (strfind(ip, "192.168.1") == 0) //0, because "192.168.1" should be found in "192.168.1.200".
//That found character 'has no characters before the sub string' (so, the found string started at index 0)
{
    //OK, Accepted LAN IP
}
else
{
    //NOK, VPN?
}

To come back to the sscanf example, this would be an alternative way:

Code:

new
    ip[] = "192.168.1.200";
    ip_part1,
    ip_part2,
    ip_part3,
    ip_part4
;
sscanf(ip, "p<.>dddd", ip_part1, ip_part2, ip_part3, ip_part4);

if (ip_part1 == 192 && ip_part2 == 168 && ip_part3 == 1 && (1 <= ip_part4 <= 255))
{
    //OK, Accepted LAN IP
}
else
{
    //NOK, VPN?
}
