Procedural Animation example in Unity.
Skeletal animation uses a key frame animation clip, which contains transforms of joints in chronological order. These pre-recorded animation clips are just "played" on a bone model.
This method uses IK (Inverse Kinematics) to procedurally position joints, so it automatically generates animation in real-time. This allows for a more diverse series of actions and real-time interaction with environmental features.
