Async

If we want to execute some behavior asynchronously on the side, while the program continues running, we can use a Async Loop or Async Task. Async behavior avoids freezing of the application.

An Async Task gets executed only once on a Bang event. Async Loop runs continuously - as fast as it can

IsAssigned gives back true if new value after execution is assigned, which allows to only show something if new value got assigned.

The Async regions also have the In Progress outputs which allow us to execute/show information while the async task is working and we want to show for example a loading screen.

HoldLatest keeps the last value it got from the async operation - until a new value comes.

The Sampler shows a value for one frame and has a OnData output which can be useful to trigger for example if conditions.

Multiple outputs

In Async Loop o Async Task if you want to output more than one value you either want to have a Recordwith your own datatype or you use Tuple(Create).
