Unity Physics overview
The Unity Physics package, part of Unity's Data-Oriented Technology Stack (DOTS), provides a deterministic rigid body dynamics system and spatial query system.
See the Unity Physics Samples for introductory material, including tutorials, samples, and videos.
Package installation
To use the Unity Physics package, you must have Unity version 2022.2.0b8 and later installed.
To install the package, open the Package Manager window (Window > Package Manager) and perform one of the following options:
- Add the package by its name (com.unity.physics)
- Add the package from its Git URL
Known issues
- Mesh collider types contacting results in a wrong behaviour by getting glued to each other as if they were joints.
- Mesh collider simplification: if primitive scale is smaller than 0.018f, selecting entities in the scene view throws error.
- Compound collider gets created even if children are disabled in Editor's game object hierarchy.
- Moving the child of a game object in a sub scene results in exceptions, when both parent and child have traditional colliders (e.g. box collider component) but no rigidbodies.
