Which component in Unity is used for character animations?

The Animator Controller is essential for managing complex animations of characters in Unity. It acts as a state machine that allows you to define various animation states and transitions based on parameters, enabling the character to perform different actions and animations smoothly. This component is crucial for providing responsive and dynamic character movement and expression, allowing the game to convey emotions and interactions through visual feedback.

Unity's Animator Controller facilitates layering animations and blending them, which helps create realistic movements, such as walking, running, jumping, or any other character actions. It integrates with the animation clips that contain the actual animated data, and through the use of triggers, booleans, and floats, developers can finely tune when and how animations are activated during gameplay.

Other options serve different purposes: the NavMesh Agent manages navigation and pathfinding, the RigidBody handles physical interactions, and the Particle System simulates particle effects like smoke or fire, demonstrating how varied components contribute to the overall game functionality. However, when it comes specifically to character animations, the Animator Controller is the core component needed for that task.
