class MoveBackwardsException

extends java.lang.Exception

Thrown if a participant makes a move that takes the partipant to a position that is approximately behind him/her and facing in approximately the same direction as the original direction faced by the participant. The algorithms for moving a participant from one position to another are very generic and can cope with most moves, but moving to a position behind and ending facing in the same direction is just not possible with two arcs of a circle. It is also ambiguous as to which way the participant should turn to make the move, and such a move would be far better specified as two or more moves. Such a movement is therefore disallowed.
