# Character control

> Configure physics-based character control for first-person and third-person characters.

In a first-person or third-person application, a user’s character or avatar usually needs some collision-based physics, so that it doesn’t fall through the floor or walk through walls. In 3D physics, you can create and configure character physics and control with a Character Controller.

You can configure character control via the [`CharacterController`](/engine/6000.3/script-reference/unityengine/charactercontroller.md) class, or the corresponding [Character Controller](/engine/6000.3/manual/physics-section/physics-overview/character-control-section/class-character-controller.md) component.
