DOTween cancellation token not immediate

See original GitHub issue

I’ve noticed that whenever I wanted to cancel a tween immediately, I’d have to wait until the end of the frame for the tween to stop. Is it possible to kill the tween immediately, so my cancel logic can become synchronous instead of asynchronous?

Ex. (What I’m doing right now)

cancelTween = new CancellationTokenSource();
await UniTask.WaitForEndOfFrame(this); // Tween is actually not cancelled yet!
transform.SetParent(canvas.transform, true); // Tween has been cancelled, now we can do what we want with the tweened object

Because of Performance (Register has allocations), it is not immediate. However, I understand the needs, I will try to find a way to implement it efficiently.

Another workaround; call tween.onUpdate just after cancel. (quite cumbersome though)

tween.onUpdate(); // Instead of WaitForEndOfFrame
transform.position =;

Looking forward to neat implementation. 👀
