How to Force a Layout Group to Rebuild
I need the updated anchored positions of a Horizontal Layout Group's children in the Start function for a component I am working on. The problem is that in the Start function all of the children return an anchored position of (0,0) because they haven't been built yet.
I can make them build like so:
public HorizontalLayoutGroup horizLayoutGroup;
public RectTransform exampleChild;
private void Start()
{
horizLayoutGroup.CalculateLayoutInputHorizontal();
horizLayoutGroup.CalculateLayoutInputVertical();
horizLayoutGroup.SetLayoutHorizontal();
horizLayoutGroup.SetLayoutVertical();
Debug.Log(exampleChild.anchoredPosition);
}
But I was wondering if there was a better way to do this.
I have also tried:
public RectTransform horizRectTransform;
public RectTransform exampleChild;
private void Start()
{
LayoutRebuilder.ForceRebuildLayoutImmediate(horizRectTransform);
Debug.Log(exampleChild.anchoredPosition);
}
But it doesn't actually seem to force the layout to rebuild, oddly enough. So if anyone can give me confirmation that this is what you're supposed to do, or a better way of doing it I would super appreciate it! Thank you!
