* "FLY/MOVE_OFF" set. This will avoid that they touch invalid objects.
* @param trap Object victim moved on.
* @param victim The object that moved on trap.
* @param originator Player, monster or other object that caused 'victim'
* to move onto 'trap'. Will receive messages caused by this action. May
* be NULL, however, some types of traps require an originator to
* function.
