This module brings Django Signals into Evennia. These are events that
|
|
can be subscribed to by importing a given Signal and using the
|
|
following code.
|
|
|
|
THIS_SIGNAL.connect(callback, sender_object)
|
|
|
|
When other code calls THIS_SIGNAL.send(sender, **kwargs), the callback
|
|
will be triggered.
|
|
|
|
Callbacks must be in the following format:
|
|
|
|
def my_callback(sender, **kwargs):
|
|
...
|
|
|
|
This is used on top of hooks to make certain features easier to
|
|
add to contribs without necessitating a full takeover of hooks
|
|
that may be in high demand.
