How to differentiate between tween completion and tween stop?

[luckyllama]

I have the following (simplified example code):

public static async UniTask AnimateOut(this VisualElement el) {
  tween = Tween.VisualElementOpacity(...); 
  await tween;

  // I only want this to run if the tween completes fully.
  el.style.display = DisplayStyle.None;
}

If the element fully animates out, I want to run some more code. If it's stopped beforehand (for instance, if somewhere else, a similar AnimateIn function is called) I don't want the code to run. I haven't found an elegant way to differentiate why the await finished waiting.

There's no OnStop callback. There's no support for a CancellationToken. I can't check the progress variable because that only works if the tween isAlive.

I'm guessing OnComplete isn't called if the tween is stopped (though I couldn't find documentation of that). But that feels clunky to use in addition to async/await. Is there an existing something that could simplify this?

Hey, OnComplete seems like a perfect match for your use case. It's okay to combine it with async/await.

You're right, OnComplete is invoked only when an animation completes to the end or Complete() is called manually.
