Код:

if(strcmp(cmd, "/destroycreatedcars", true) == 0)
  {
   if(PlayerInfo[playerid][pAdmin] >=8)
   {
     for(new x=349;x<MAX_VEHICLES;x++)if(IsVehicleConnected(x)) DestroyVehicle(x);
             return 1;
   }

  }

Код:

stock IsVehicleConnected(vehicleid) // Mастерминд
{
  new Float:x, Float:y, Float:z;
  GetVehiclePos(vehicleid, x, y, z);
  if(x == 0.0 && y == 0.0 && z == 0.0) return 0;
  return 1;
}
