So hai guys, today I'll teach you guys how to make a simple countdown system

to begin we'll create a variable:

pawn Код:

new CountDown = -1;

We forward the countdown

pawn Код:

forward countdown();

Then we'll create the public function for the countdown

pawn Код:

public countdown()
{
    return 0;
}

and inside the countdown() we'll put:

pawn Код:

public countdown()
{
    if(CountDown == 6) GameTextForAll("~w~Starting...",1000,6); // Sends a message saying Countdown is starting
    CountDown--; // And make sure to decrease its value by using '--'
    if(CountDown==0) // Here we check if Countdown reaches 0 Seconds
    {
        GameTextForAll("~g~GO~ r~!",1000,6); // Sends a gametext for all saying GO
        CountDown = -1; // and setting the CountDown to -1
        for(new i; i < MAX_PLAYERS; i++) // Here we make a Loop
        {
            PlayerPlaySound(i, 1057, 0.0, 0.0, 0.0); // and on the countdown we give a sound
        }
        return 0;
    }
    else
    {
        new text[7]; // Here we create a variable of 7 size
        format(text,sizeof(text),"~w~%d",CountDown); // Format the countdown message
        for(new i; i < MAX_PLAYERS; i++)  // We Loop again
        {
            PlayerPlaySound(i, 1056, 0.0, 0.0, 0.0); // Plays sounds on Countdown
        }
        GameTextForAll(text,1000,6); // And displays Countdown for everyone
    }
    SetTimer("countdown",1000,0); // and here we set the timer of countdown
    return 0;
}

and then go to

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])

and we'll create the command /countdown by:

pawn Код:

if(!strcmp(cmdtext, "/countdown", true))
{
    if(CountDown == -1) // When countdown is on -1
    {
        CountDown = 6; // We set 6 on Countdown variabel
        SetTimer("countdown", 1000, 0); // and we set Timer for every second of the countdown
    }
    return 1;
}

and heres the full code:

pawn Код:

new CountDown = -1;
forward countdown();
public countdown()
{
    if(CountDown == 6) GameTextForAll("~w~Starting...",1000,6);
    CountDown--;
    if(CountDown==0)
    {
        GameTextForAll("~g~GO~ r~!",1000,6);
        CountDown = -1;
        for(new i; i < MAX_PLAYERS; i++)
        {
            PlayerPlaySound(i, 1057, 0.0, 0.0, 0.0);
        }
        return 0;
    }
    else
    {
        new text[7];
        format(text,sizeof(text),"~w~%d",CountDown);
        for(new i; i < MAX_PLAYERS; i++) 
        {
            PlayerPlaySound(i, 1056, 0.0, 0.0, 0.0);
        }
        GameTextForAll(text,1000,6);
    }
    SetTimer("countdown",1000,0);
    return 0;
}
public OnPlayerCommandText(playerid, cmdtext[])
{
    if(!strcmp(cmdtext, "/countdown", true))
    {
        if(CountDown == -1)
        {
            CountDown = 6;
            SetTimer("countdown", 1000, 0);
        }
        return 1;
    }
    return 0;
}
