Create own listener

[decompile]

Hey,

Im currently writing a quick afk manager api and I thought it would be good to add a "On Player AFK" listener and reverse.

Couldnt understand it from wikis

Hey !

I have one solution but i don't know if it's the best xD.

Syntax: Select all

## listeners.py

## IMPORTS

from listeners import ListenerManager
from listeners import ListenerManagerDecorator

## ALL DECLARATION

__all__ = (
    'OnPlayerAfk',
    )

class OnPlayerAfk(ListenerManagerDecorator):
    manager = ListenerManager()

Syntax: Select all

from .listeners import OnPlayerAfk

# In your fonction which check afk
def _on_afk_check():
    OnPlayerAfk.manager.notify(player=player)

@OnPlayerAfk
def _on_player_afk(player):
    # Do something

If i m not wrong :)

Yep, that's exactly how you do it.

Why do we need that __all__ or what is it function?

[Predz]

The __all__ attribute allows python to know what to define when trying to import from a module.

Doing:

Syntax: Select all

from <module> import *

Would import all things from the <module> but only define values which are named from inside the iterable.

You can still do:

Syntax: Select all

from <module> import <object>

The * is just a way of checking what is inside __all__

To clarify it: you don't need it, but it's commonly used when creating modules to prevent cluttering your namespace when you import everything with the asterisk.
