/*
|
||||
This object is contained within zone/var/connections. It's generated whenever two turfs from different zones are linked.
|
||||
Indirect connections will not merge the two zones after they reach equilibrium.
|
||||
|
||||
Overview:
|
||||
Connections are made between turfs by air_master.connect(). They represent a single point where two zones converge.
|
||||
|
||||
Class Vars:
|
||||
A - Always a simulated turf.
|
||||
B - A simulated or unsimulated turf.
|
||||
|
||||
zoneA - The archived zone of A. Used to check that the zone hasn't changed.
|
||||
zoneB - The archived zone of B. May be null in case of unsimulated connections.
|
||||
|
||||
edge - Stores the edge this connection is in. Can reference an edge that is no longer processed
|
||||
after this connection is removed, so make sure to check edge.coefficient > 0 before re-adding it.
|
||||
|
||||
Class Procs:
|
||||
|
||||
mark_direct()
|
||||
Marks this connection as direct. Does not update the edge.
|
||||
Called when the connection is made and there are no doors between A and B.
|
||||
Also called by update() as a correction.
|
||||
|
||||
mark_indirect()
|
||||
Unmarks this connection as direct. Does not update the edge.
|
||||
Called by update() as a correction.
|
||||
|
||||
mark_space()
|
||||
Marks this connection as unsimulated. Updating the connection will check the validity of this.
|
||||
Called when the connection is made.
|
||||
This will not be called as a correction, any connections failing a check against this mark are erased and rebuilt.
|
||||
|
||||
direct()
|
||||
Returns 1 if no doors are in between A and B.
|
||||
|
||||
valid()
|
||||
Returns 1 if the connection has not been erased.
|
||||
|
||||
erase()
|
||||
Called by update() and connection_manager/erase_all().
|
||||
Marks the connection as erased and removes it from its edge.
|
||||
|
||||
update()
|
||||
Called by connection_manager/update_all().
|
||||
Makes numerous checks to decide whether the connection is still valid. Erases it automatically if not.
