Parent matches child's rotation

hi,

I'd like the parent's rotation to match the rotation of it's child at some point.

I tried many solutions without success. My basic approach was :

parent.transform.rotation = child.transform.rotation;

as rotation is world based, I expected it to work but... no.

any idea ?

 

it should work, but they won't align.
lets say Parent is at 5 degrees
child is at 10 degrees
after your operation,
parent = 10 degrees.
but since child is .. a child, it will be moved accordingly, so since child's local rotation is 5 degrees (relative to parent) child will now be 15 degrees, still 5 degrees more than the parent.

to have them align, just call child.transform.localRotation = Vector3.zero immediately after your operation.

 

I don't want them to align at the end. I just want the parent to align to the child before rotation. So in your example, the parent = 10 degrees and child = 15 degrees is exactly what I want.

But I found another way to achieve what I want, thanks.
