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

Summary


In this chapter, we introduced the Blend Tree as a method of blending similar animations to create more realistic animated responses during the game.

Our exercises demonstrated two different implementations of this:

In the first example, we added strafe animations to the Idle state to give the player feedback when moving from side to side.

In the second implementation, we created variation in the pickup animation by blending light and heavy variations of the motion sequence based on the determined weight of the object that was picked up.

In the next chapter, we will return to the enemies to demonstrate ragdoll effects.

As a physics effect, the ragdoll prefab is commonly used to simulate the physical properties of weight and force resulting in more convincing death sequences for player and non-player character objects.

Although these physics effects do not use the Mecanim toolset, they will complement our state machine by adding further realism to our enemy and environment in the game.
