Function to check for players with same IP on same map

[Ridley]

This function will check for players with the same IP on the same map.

In the sample, if it finds a player with the same IP on said map, you get warped back to prontera and kicked.

Note: Don't use it recklessly or else you spam your mapserver and might kill it.

function script char_same_unique_id {
.@my_map$ = getarg(0);
// get array of char names who are online from the same IP
query_sql "SELECT `char`.`name` FROM `char` LEFT JOIN login ON `char`.account_id=login.account_id " +
"WHERE last_ip=(SELECT last_ip FROM login WHERE account_id="+playerattached()+") AND online AND `char`.account_id!=" + playerattached(), .@name$;
// check each char, and see if they are on the map
for (.@i = 0; .@i < getarraysize(.@name$); .@i++) {
getmapxy .@map$, .@x, .@y, 0, .@name$[.@i];
if (.@map$ == .@my_map$)
return 1; // another char from this IP is already on that map
}
return 0; // no other chars from this IP are on that map
}

dispbottom("No dual clienting in BG please.");
warp("prontera",156,184);
