static int UpdateTrainSpeed | ( | Vehicle * | v | ) | [static] |
This function looks at the vehicle and updates it's speed (cur_speed and subspeed) variables.
Furthermore, it returns the distance that the train can drive this tick. This distance is expressed as 256 * n, where n is the number of straight (long) tracks the train can traverse. This means that moving along a straight track costs 256 "speed" and a diagonal track costs 192 "speed".
