Child transform's position not updated as parent moves

Question

I have a parent game object Object1. It has a child, which is simply an empty game object called ReferencePoint. ReferencePoint can be any arbitrary point on Object1 itself.

I have another game object Object2. It has a public field called RotationReference, of type Transform. In the inspector, the ReferencePoint on Object1 is assigned to the RotationReference field on Object2.

As Object1 moves, I expect ReferencePoint to change its position as well. Object2 is supposed to change its rotation to face its RotationReference -- in this case, the ReferencePoint on Object1:

public override void Rotate()
{
    Vector3 relativeRotationReferencePosition =
        this.RotationReference.position - this.transform.position;

    this.transform.rotation = Quaternion.LookRotation(relativeRotationReferencePosition);
}

However, I noticed that Object2 is not rotating at all, even when Object1 is moving. When I step through the call stack multiple times, I discover that this.RotationReference.position always has the same value, even though Object1 is moving.

What am I missing here?

Answer 1

If the problem is that the position itself does not change, probably it is due to some mistake in assigning a value to rotationReference. Check that you do not change its value anywhere in the code. And it is "RotationReference = ReferencePoint" not the other way round and so on.

Also I don't see why you need referencePoint on object1 and not just use Object1 itself as the target. But maybe I just don't understand what you're trying to do.
