Trackdir RoadVehicle::GetVehicleTrackdir | ( |  | ) | const`[virtual]`

Returns the Trackdir on which the vehicle is currently located.

Works for trains and ships. Currently works only sortof for road vehicles, since they have a fuzzy concept of being "on" a trackdir. Dunno really what it returns for a road vehicle that is halfway a tile, never really understood that part. For road vehicles that are at the beginning or end of the tile, should just return the diagonal trackdir on which they are driving. I _think_. For other vehicles types, or vehicles with no clear trackdir (such as those in depots), returns 0xFF.

Returns:
  the trackdir of the vehicle
