Sleeptimers

This guide has very similar principles and implementation to Saving Progress. First please read through that guide to understand the concept of "remote" playback and why coupling playback events to the UI is a bad idea.

Once you've understood that concept, this concept is nearly identical. You would leverage the same Event.PlaybackProgressUpdated event in this scenario too.

Here's how you would use an event to implement a sleep timer:

1. The user configures a sleep timer in the UI.
2. Persist the time they configure in a store as a timestamp.
3. Each time the progress event fires you check your persisted sleep timer timestamp.
   • IF sleeptime !== null && sleeptime <= now THEN pause.
