Dotween: LoopType.Yoyo work as LoopType.Restart

[ShadowTM]

Hi! I use async version DoTween 1.2.365 anf have problem in this code:

_tweener = element.transform.DOScale(new Vector3(1.25f, 1.25f, 1.25f), 0.5f)
.SetLoops(-1, LoopType.Yoyo)
.Play();

LoopType.Yoyo working as LoopType.Restart. What is the problem?

Yes, I have the same issue, that seems because of this commit.

And I fixed this by changing
bool useInversePosition = t.loops > 1 && t.loopType == LoopType.Yoyo && (t.position < t.duration ? t.completedLoops % 2 != 0 : t.completedLoops % 2 == 0);
to
bool useInversePosition = (t.loops == -1 || t.loops > 1) && t.loopType == LoopType.Yoyo && (t.position < t.duration ? t.completedLoops % 2 != 0 : t.completedLoops % 2 == 0);

@Demigiant Is this modification OK?

Thanks for the pinpoint, investigating it! :)

And you were completely right, here's an updated version that fixes that :)

I made a thorough check and found a similar bug in path tweens and infinite Yoyo loops, which I now fixed there too.

Thank! Great job.
