Good day. I have the following function in my code.

Code: (CSharp) [Select]

IEnumerator NextStep () {
        Color newCol = Color.white;
     
        DOTween.To (()=> newCol, c => newCol = c, Color.black, 0.4f)
            .OnUpdate (delegate () {
                cam.backgroundColor = newCol;
                logoCrystal.color = newCol;
            });

        yield return new WaitForSeconds (0.3f);

        logo.transform.DOLocalMoveX (1f, 0.5f);

        yield return new WaitForSeconds (0.2f);

        logoPainting.DOColor (Color.white, 0.4f);

        yield return new WaitForSeconds (0.5f);

        tapText.DOColor (Color.white, 0.3f)
            .OnComplete (delegate() {
                tapText.DOColor (new Color (1f, 1f, 0.8f), 0.15f).SetLoops(-1, LoopType.Yoyo);
                inputAllowed = true;
            });
    }
It throws the following error upon compilation:

Unhandled Exception: Mono.CSharp.InternalErrorException: Assets/Scripts/Utils/TitleScene.cs(65,42): ---> System.ArgumentOutOfRangeException: Argument is out of range.

Line 65 corresponds to the first DOTween call in my snippet. Further more, adding

Code: (CSharp) [Select]

yield return new WaitForSeconds (0f);
will resolve the error.

I searched for any similar cases, but the closest I found would be the InternalErrorException caused by named parameters which is no the case in my code. Any ideas on this? Thank you very much,

Hi,

I'm kind of confused by this. Can you recreate this issue in a sample project and attach the unitypackage here, so I can check it out?

Cheers,
Daniele
