Inherits from:Component

Implemented in:UnityEngine.Physics2DModule
Provides physics movement and other dynamics, and the ability to attach Collider2D to it.
The Rigidbody2D is a fundamental physics component that provides multiple simulation dynamics, such as Rigidbody2D.position and Rigidbody2D.rotation for pose control, and Rigidbody2D.linearVelocity and Rigidbody2D.angularVelocity for velocity control.
You can attach multiple Collider2D to a Rigidbody2D to detect collisions and provide a collision response when you set Rigidbody2D.bodyType to RigidbodyType2D.Dynamic.
