I am going to explain it a little bit

On top of your script, pretty basic - add

pawn Код:

forward countdown(playerid, seconds);
new countdowntime, tCountdown;

Now we gotta add the timer you need for the countdown. Add this in the area command

pawn Код:

countdowntime = 3;
tCountdown = SetTimerEx("countdown", 1000, true, "i", playerid);

It will set a Timer to run. We repeat it all the time till it gets killed. The "i" is defining the playerid (else only playerid 0 will be called)

Now we need to create the public function

pawn Код:

public countdown(playerid, seconds)
{
    if(countdowntime  >= 1)
    {
        countdowntime --;
        format(string, sizeof string, "%i", countdowntime);
        GameTextForPlayer(playerid, string, 1000, 4);
    }
    else
    {
        GameTextForPlayer(playerid, "0", 1000, 4);
        KillTimer(tCountdown);      
        countdowntime = 3;
    }
    return 1;
}

If you wonder why I set it to if(countdowntime >= 1). Well, we gotta end it at 0 right? At 0 it will kill the timer.

You can try and see if it works. If it doesn't or you get errors/warnings, please post them
