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

Adding the snarl face animation to the female zombie character


Before we get to grips with the animator controller and the script, let's take a look at the scene and run through the zombie's current behavior. The environment is the simple conference room used in Chapter 5, Retargeting Animation.

Setting the scene in Unity

Our starting scene includes the conference room environment, the first person controller and a single enemy—the female zombie introduced in Chapter 2, Rigging Characters for Unity in 3ds Max and Maya.

  1. Open the scene Chapter6_Start within the Unity project.

  2. Preview the scene by pressing the Play button in the top center of the Unity interface.

With the first-person controller, we can navigate through the space toward the enemy.

The female zombie idles for a while before walking forward. At the moment, we can get close to the zombie without seeing any kind of change in its behavior.

We will add some basic functionality to the script to lay the groundwork for our snarl animation...
