Combine or connect shapes, and enable and detect contact between physics objects using the Physics Core 2D API.
Note: This documentation is about writing C# scripts using the Unity.U2D.Physics API. To use 2D physics in the Unity Editor using components like the Rigidbody 2D component, refer to 2D physics instead.
| Topic | Description |
|---|---|
| Introduction to collision in the Physics Core 2D API | Learn about collisions between 2D physics objects, including collision types, layers, and layer masks. |
| Configure collisions between objects | Change which objects collide with which using layers and masks, and enable using 64 layers instead of 32. |
| Detect collisions between objects | To detect when collisions occur and respond to them, use collision callback methods or event methods. |
| Check Physics Core 2D API intersections | To check whether 2D physics objects overlap or will collide, also known as intersections, use query methods. |
