asyncgui-ext-clock

Clock

Event scheduler designed for asyncgui programs.

import asyncgui
from asyncgui_ext.clock import Clock

clock = Clock()

async def async_fn():
    await clock.sleep(20)  # Waits for 20 time units
    print("Hello")

asyncgui.start(async_fn())
clock.tick(10)  # Advances the clock by 10 time units.
clock.tick(10)  # Total of 20 time units. The task above will wake up, and prints 'Hello'.

The example above effectively illustrate how this module works but it's not practical. In a real-world program, you probably want to call clock.tick() in a loop or schedule it to be called repeatedly using another scheduling API. For example, if you are using PyGame, you may want to do:

pygame_clock = pygame.time.Clock()
clock = asyncgui_ext.clock.Clock()

# main loop
while running:
    ...

    dt = pygame_clock.tick(fps)
    clock.tick(dt)

And if you are using Kivy, you may want to do:

from kivy.clock import Clock

clock = asyncui_ext.clock.Clock()
Clock.schedule_interval(clock.tick, 0)
