Configure global LowLevelPhysics2D API settings

Note: This documentation is about writing C# scripts using the LowLevelPhysics2D API. To use 2D physics in the Unity Editor using components like the Rigidbody 2D component, refer to 2D physics instead.

To configure global settings for the LowLevelPhysics2D API, create and assign a Physics Low Level Settings 2D asset. Follow these steps:

1. In the Project window, select Assets > Create > 2D > Physics LowLevel Settings.

2. From the main menu, select Edit > Project Settings.

3. In the Project SettingsA broad collection of settings which allow you to configure how Physics, Audio, Networking, Graphics, Input and many other areas of your project behave. More info
   See in Glossary window, select Physics 2D, then the Low Level tab.

4. Drag the Physics LowLevel Settings 2D asset from the Project window to the Physics Low Level Settings setting.

The 2D physics system now uses the settings in the asset.

Configure the settings

For more information about configuring each section of the settings, refer to the following:

• Configure collisions between LowLevelPhysics2D API objects for using and editing the Layers setting.
• Configure LowLevelPhysics2D API scenes with definitions for editing the Default Definitions settings.
• Physics Low Level Settings window reference for information about the Global settings.
