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

Loading the scene


This time, the starting scene has been prepared. It includes a basic environment, lighting and the zombie_f prefab already set up to work with Mecanim.

In the Unity project, open the scene Chapter5_Start. The scene will load. The female zombie already has an Avatar, and has an animator component attached to it, containing a single, idling animation unique to the character.

The zombie_f prefab also has a short script, which is set up ready to play the idle and walk sequences:

Adding and previewing the animation

At this point we will add one of the walk sequences to the zombie's animator controller:

  1. Click the Animator tab to view the character's animator controller.

  2. In the Animator window, click the Walk state to view its parameters in the Inspector panel.

  3. In the Project panel, click the PACKT_Animations folder to view its contents in the Assets panel.

  4. Locate the zombie_walk asset and click the small arrow to the right of its icon to view its contents.

  5. Drag zWalk01 from the Assets...
