Don't really know how efficient this is but ought to work (not tested):

Код:

new StopKwak[MAX_PLAYERS]; //at the top of your script
forward AllowKwak(playerid);

Код:

OnPlayerText(playerid, text[])
{
     if(!strcmp(text, "kwakbox",false, 7))
     {
         if(StopKwak[playerid] == 0)
         {
               StopKwak[playerid] = 1;
               SetTimerEx("AllowKwak", 300000, false, "i", playerid);
         }
         else
         {
               SendClientMessage(playerid, 0xFF0000, "Please wait 5 minutes before saying kwakbox again!");
               return 0;
         }
      }
      return 1;
}

Код:

public AllowKwak(playerid) //anywhere in your script
{
     StopKwak[playerid] = 0;
}
