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 and implementing collectable objects

Typically, in a game, the player will be able to collect power-ups to increase their effectiveness, or to replace depleted life or energy.

In this game, our player will collect food to boost his health. This stage will involve adding a collectable and making the player react with a suitable animation sequence.

Instantiating the lunchBox collectable in the game level

Our first collectable is already set up as a prefab in the project files, making it easy to drag and drop into our game level without having to add components and set variables:

  1. In the Project panel, locate the PACKT_Prefabs folder.

  2. Click to expand the Pickups subfolder and locate the lunchBox prefab.

  3. Drag lunchBox into the Hierarchy panel to instantiate it.

  4. Position the prefab and navigate within the Scene view until it is clearly visible:

Inspecting the lunchBox collectable's components

The lunchBox prefab is a game object with a few components attached. We will take a look and see how it...
