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 air_master.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.
