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

Creating the ragdoll object


We will create the ragdoll prefab using our female zombie character. We need to make a few changes to the scene before we add the character model:

  1. Delete the Sphere and Cube objects.

  2. In the Hierarchy panel, select the groundPlane game object.

  3. In the Inspector panel, set the groundPlane object's Transform Scale field's X and Z values to 0.5.

  4. In the Project panel, click on the FBX_Imports folder to view its contents in the Assets panel.

  5. In the Assets panel, locate zombie_f and drag it into the Hierarchy panel, instancing it in your scene.

    Note

    In previous chapters, we have already created an enemy character prefab from this model, but for the ragdoll prefab we do not need the character controller, animator controller, or behavior script, so it saves time to just create the ragdoll from the source model.

The female zombie model will load in the scene with the default material. We can add the correct material next.
