changes: MultiZAS now actually works. The ZAS connection diagnostic verb is now aware of MultiZ. Potential performance improvement for ZAS connections. Probably should not be merged until shuttles have roofs unless people want to take their chances at outrunning ZAS getting off the shuttle.

Overview:
|
|
The connection_manager class stores connections in each cardinal direction on a turf.
|
|
It isn't always present if a turf has no connections, check if(connections) before using.
|
|
Contains procs for mass manipulation of connection data.
|
|
|
|
Class Vars:
|
|
|
|
NSEWUD - Connections to this turf in each cardinal direction.
|
|
|
|
Class Procs:
|
|
|
|
get(d)
|
|
Returns the connection (if any) in this direction.
|
|
Preferable to accessing the connection directly because it checks validity.
|
|
|
|
place(connection/c, d)
|
|
Called by SSair.connect(). Sets the connection in the specified direction to c.
|
|
|
|
update_all()
|
|
Called after turf/update_air_properties(). Updates the validity of all connections on this turf.
|
|
|
|
erase_all()
|
|
Called when the turf is changed with ChangeTurf(). Erases all existing connections.
|
|
|
|
check(connection/c)
|
|
Checks for connection validity. It's possible to have a reference to a connection that has been erased.
