Unity Character Animation with Mecanim

By: Jamie Dean

Overview of this book

Game animation for independent developers has taken a giant leap forward with Unity 5's Mecanim toolset, which streamlines the import/export, retargeting, and many other aspects of the character animation workflow. Unity Character Animation with Mecanim is a great primer for getting to know the nuts and bolts of Mecanim and other character animation related tools in Unity 5. It offers you step-by-step instructions for preparing and exporting rigged models and animation sequences from commonly used 3D packages, such as Maya, 3ds Max and Blender. This book explores the new set of animation tools introduced with Mecanim in Unity 5. Approaching its subject matter through a typical genre–a zombie action game, character animation techniques are explored using real examples of player input and interaction, enemy behavior, and other aspects of game dynamics. As the book progresses, the reader will understand how these elements fit together in a small game development workflow. We will begin with a demonstration of the process of getting a rigged character into Unity 5 and setting it up to use provided animation sequences. We will also consider a few industry standard 3D packages and how these can be used to rig a humanoid character for use in Unity 5. We will demonstrate the retargeting capabilities of Mecanim’s Humanoid Animation type by adjusting motion sequences to fit disparate character types in our game. After this, we will look at Ragdoll physics and the implementation of this commonly used technique in a Mecanim workflow. The book culminates with a thorough dissection of the enemy character AI script incorporating the Mecanim elements detailed in the previous chapters. Unity Character Animation with Mecanim will provide you with a detailed exploration of the interaction between game development and character animation, and will broaden your understanding of the rich animation toolset within Unity 5

Introduction to motion capture sequences and their characteristics


In short, motion capture is an attempt to record the simultaneous movement of items (usually the joints or bones of the human body).

Motion capture sequences have been successfully created in a number of ways:

  • Motion capture suits contain a number of sensors that return the actual joint rotations as an actor is performing an action

  • Optical motion capture often uses cameras to pinpoint the position of key markers within three-dimensional space.

In the past, both of these methods required special equipment and, consequently, were very expensive. Advances in movement control in game consoles such as Wii, Playstation, and Xbox have made simple motion capture using markerless motion capture more affordable and accessible.

The motion capture sequences provided as examples with this book were captured with a Kinect sensor connected to a PC. Motion capture is used in video games for the same reasons that it is used in visual effects in...
