cara eu não aconselho você a usar esse ARconnect, eu usei ele por um tempo, as vezes ele começa a kickar todo mundo.

@TOPIC:

stock GetNumberOfPlayersOnThisIP(test_ip[])
{
    new against_ip[32+1];
    new x = 0;
    new ip_count = 0;
    for(x=0; x<MAX_PLAYERS; x++) {
        if(IsPlayerConnected(x)) {
            GetPlayerIp(x,against_ip,32);
            if(!strcmp(against_ip,test_ip)) ip_count++;
        }
    }
    return ip_count;
