Creating a 2D doll animation uses the same concept as shown in the Using the Hierarchy to animate local rotation - creating an orbiting planet recipe in Chapter 2, Working with the Animation View. The key element of this recipe is the Warrior root game object containing all the body parts of our character as children game objects. When we select this object and open the Animation View, we can animate all its children game objects. The saved Animation Clip will be used by the Warrior game object's Animator Controller. That allows us to create complex hierarchical animations (such as this one) and save them as single Animation Clips.
