Or this:

pawn Код:

#include <a_samp>

new bool:g_switch[MAX_PLAYERS];

public OnPlayerConnect(playerid)
{
    g_switch[playerid] = true;
    return true;
}

forward SwitchVar(playerid);
public SwitchVar(playerid)
{
    if(IsPlayerConnected(playerid) && !IsPlayerNPC(playerid)) g_switch[playerid] = true;
    return true;
}

public OnPlayerUpdate(playerid)
{
    if(g_switch[playerid])
    {
        g_switch[playerid] = false;
        SetTimerEx("SwitchVar", 1000, false, "i", playerid);
        SendClientMessage(playerid, -1, "Update/sec..");
    }
    return true;
}

But with lots of players in your server, its laggy (i think)
