This chapter explains the usage of animations for character actions and expressions and covers the following recipes:

• Creating an appear or a disappear animation
• Creating background characters and critters with animation-driven behavior
• Using Blend Trees to create randomized actions
• Using Quaternion.LookRotation() and Animator.SetLookAtPosition() methods to make characters follow an object with their gaze
• Action Points - performing an action in a specified spot
• Synchronizing an animation with objects in the scene
• Using IK for interacting with scene objects
