Delete:

pawn Код:

DownSweeper[playerid] = 1;
SetTimer("CoolSweeper", 3600000, false);

and replace it with this:

pawn Код:

DownSweeper[playerid] = GetTickCount()+3600000;

Put this in the /sweepagain command you was talking about:

pawn Код:

if(DownSweeper[playerid] > GetTickCount())
{
    new string[60], time=DownSweeper[playerid]-GetTickCount();
    time/=1000, time/=60;
    if(time > 1)
        format(string,sizeof(string),"Please wait %d minutes before using this command again!", time);
    else if(time == 1)
        format(string,sizeof(string),"Please wait 1 minute before using this command again!");
    else
        format(string,sizeof(string),"Please wait a few seconds before using this command again!");
    SendClientMessage(playerid, 0xFF0000FF, string);
    return 1;
}

Also, you no longer need:

pawn Код:

public CoolSweeper()
{
    DownSweeper[playerid] = 0;
}

If you need to check if the cooldown is over or not, use this:

pawn Код:

if(DownSweeper[playerid] > GetTickCount())

Sorry if I made things confusing, but this way you don't need to use a timer, and can also see how long of the cooldown is remaining.
