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:
| Topic | Description |
|---|---|
| Rigidbody 2D | Learn how RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info See in Glossary 2D works. |
| Collider 2D | Understand the types of ColliderAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info See in Glossary 2D components available to use with Rigidbody 2D. |
| Physics Material 2DUse to adjust the friction and bounce that occurs between 2D physics objects when they collide More info See in Glossary |
Control the friction and bounce between colliding 2D physics objects. |
| 2D Joints | Understand the types of 2D JointsA physics component allowing a dynamic connection between Rigidbody components, usually allowing some degree of movement such as a hinge. More info See in Glossary available to use with 2D GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info See in Glossary. |
| Constant Force 2D | Add constant forcesA simple component for adding a constant force or torque to game objects with a Rigidbody. More info See in Glossary to a Rigidbody 2D. |
| Effectors 2D | Direct the forces of physics when GameObject colliders are in contact. |
