public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
  if (newkeys == KEY_WALK)
     {
            if(IsPlayerInAnyVehicle(playerid))
            {
            new VehicleID, Float:X, Float:Y, Float:Z, Float:Angle;
            GetPlayerPos(playerid, X, Y, Z);
            VehicleID = GetPlayerVehicleID(playerid);
            GetVehicleZAngle(VehicleID, Angle);
            SetVehiclePos(VehicleID, X, Y, Z);
            SetVehicleZAngle(VehicleID, Angle);
            SetVehicleHealth(VehicleID,1000.0);
          }
