How to update a RectTransform's AnchoredPosition when its pivot is changed

Unity Engine

Asking this here since I cannot find a forum related to UI that is alive.

I am changing the pivot of a RectTransform at runtime and want to take the new anchoredPosition that results from this change and use it for tweening.

However the value I get from panel.anchoredPosition.y is still the old anchoredpos. I tried waiting for 1-2 frames before asking for the value, I tried panel.ForceUpdateRectTransforms(), no result.

I would simply author a separate invisible GameObject that you use as the pivot.

The reason is that manipulating RectTransforms is almost always a complicated disaster.

For instance it is some 15 lines of code just to set the anchors to the outside of the RectTransform.

because changing the pivot doesnt change the anchored position

it does in the editor but that is because the editor is wacky

what you need is a formula that copies the wacky behaviour of the unity editor

with that being said when the moderators find this thread they are gonna send u back to the shadow realm
