/* PartyPathFinder moves the entire party at once.

|
* FIXME: Move to target if one square away and unblocked. Shamino isn't in the
|
|
* correct square after moving through a doorway.
|
|
* FIXME: Perhaps is_contiguous() should require everyone in front of a follower
|
|
* to also be contiguous. If more than one followers are lost, they stay
|
|
* together more than look for the leader.
|
|
* FIXME: When walking along the wall, the last follower doesn't move up when
|
|
* there is a closer free square. (it sometimes behaves the same way in U6)
|
|
* FIXME: If a higher-number follower is closer to the leader than a lower-numbered
|
|
* one, the one with higher priority bumps him out of the way, and he loses a
|
|
* move. This causes him to become non-contiguous. Followers should NEVER be
|
|
* moved to non-contiguous squares. Strangely, this only happens when moving in
|
|
* certain directions. (disable SEEK mode to check)
|
|
* FIXME: When changing directions, followers on opposite sides of the party
|
|
* (perpendicular to the forward direction) shouldn't exchange positions until
|
|
* the leader stops.
