A small but effective countdown, by me :


First some variables needed :

pawn Код:

new countdown_seconds,
  countdown_string[40];

Under OnGameModeInit :

pawn Код:

SetTimer("countdown_timer",1000,true);

The dcmd command :

pawn Код:

dcmd_countdown(playerid, param[])
{
  new seconds = strval(param);
    
  if (countdown_seconds)
    SendClientMessage(playerid,0xFF0000FF,"A countdown is already started.");

  else if (seconds < 3 || seconds > 300)
    SendClientMessage(playerid,0xFF0000FF,"You must enter a duration between 3 and 300.");

  else
  {
    format(countdown_string,40,"You started a countdown of %d seconds.",seconds);
    SendClientMessage(playerid,0x00FF00FF,countdown_string);
    countdown_seconds = seconds+1;
  }
    
  return 1;
}

The timer:

pawn Код:

public countdown_timer()
{
  if (countdown_seconds)
  {
    format(countdown_string,6,"~w~%d",countdown_seconds-1);
    GameTextForAll(countdown_string,1100,4);
    SoundForAll(1056);

    countdown_seconds --;

    if (!countdown_seconds)
    {
      GameTextForAll("~r~go !",2000,4);
      SoundForAll(1057);
    }
  }
}

The function i used to play sounds:

pawn Код:

SoundForAll(sound)
{
  for (new i = 0, j = GetMaxPlayers(); i < j; i ++)
    if (IsPlayerConnected(i))
      PlayerPlaySound(i,sound,0.0,0.0,0.0);
}

Thanks for pointing that boylett , i added a min and max limit and changed the order of errors messages.
