In Flash, you can use inverse kinematics to animate one or more objects in relation to each other. Inverse kinematics is an animation method used to create bone structures. A bone is a link from one symbol instance to another or from one interior part of a shape to another. When one bone moves, the other bones move in relation to it. With inverse kinematics, you can easily create complex animations and natural movement. For example, you can create character animation in which the arms and legs of a body are connected to each other with bones. When a bone in one part of the character moves, the other bones move accordingly without you defining every single movement. You specify only the start and end positions of an object by positioning its bones. A chain of bones is called an armature. Bones can be added to connect one symbol instance to another, or they can be added to the interior of a shape object so you can move or animate parts of the shape without having to draw the shape multiple times. When you add bones to a symbol instance or to a shape, the instance or shape and its armature are moved to a new layer called a pose layer.
