I have a knife sprite which I’d like to rotate using custom rotation pivot, let it be knife’s handle center. I know it’s possible to change rotation pivot for Sprite node, but the sprite is a child of CollisionPolygon2D which has RigidBody2D as its parent and toolbar button that changes object’s rotation pivot is disabled for CollisionPolygon2D and RigidBody2D, so I need to find another way.

So this is the hierarchy:

Node2D
    RigidBody2D
        CollisionPolygon2D
            Sprite

Question: Can I have a Position2D somewhere under RigidBody2D to rotate CollisionPolygon2D and Sprite simultaneously? So that if the knife is flying I could still rotate it using my custom rotation point.
