We will start by adding a new (pretty simple) module to our project (call it ue_asyncio.py):

import asyncio

import unreal_engine as ue

loop = asyncio.new_event_loop()

def ticker_loop(delta_time):

try:

loop.stop()

loop.run_forever()

except Exception as e:

ue.log_error(e)

return True

ticker = ue.add_ticker(ticker_loop)

Do not run this module, it will be just the 'hub' the other parts of our project will connect too.

Basically when you first import this module a new 'ticker' will be registered into Unreal Engine. A ticker is a function that periodically 'ticks'. In this case Unreal Engine will use this ticker function to wake up the asyncio loop engine to manage all of the coroutines registered to it.

Let's start with the previous timer example:
