Create and control a 2D physics scene in a C# script using the

Unity.U2D.Physics

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
Get started with the Physics Core 2D API	Learn about the `Unity.U2D.Physics` API and how to create a 2D physics scene.
Creating a scene with the Physics Core 2D API	Create and debug a scene that uses 2D physics.
Configuring Physics Core 2D API scenes	Configure 2D physics objects and global settings, and attach custom data to physics objects.
Collisions and interactions in the Physics Core 2D API	Enable and detect collisions between 2D physics objects, and cast rays to check for intersections.
Run 2D physics in 3D space using the Physics Core 2D API	Create a 2D physics world at any angle in 3D space, instead of the traditional x, y plane that faces the camera.
Optimize the Physics Core 2D API	To improve the performance of 2D physics, run the simulation and your own code on multiple threads.
Reference for the Physics Core 2D API	Explore the properties and settings you can use to configure the global settings of the Physics Core 2D API, and set the default values for objects like worlds, bodies, and shapes.
