Unity’s physics system lets you handle 2D physics to make use of optimizations available with 2D. You can use the following physics 2D components with Unity:
| 항목 | 설명 |
|---|---|
| Rigidbody 2D | Learn how Rigidbody 2D works. |
| Collider 2D | Understand the types of Collider 2D components available to use with Rigidbody 2D. |
| Physics Material 2D | Control the friction and bounce between colliding 2D physics objects. |
| 2D Joints | Understand the types of 2D Joints available to use with 2D GameObjects. |
| Constant Force 2D | Add constant forces to a Rigidbody 2D. |
| Effectors 2D | Direct the forces of physics when GameObject colliders are in contact. |
