Unity’s built-in 3D physics engine is an integration of the Nvidia PhysX engine. You can use this engine in object-oriented 3D projects.
This section includes the following topics.
| Topic | 描述 | 
|---|---|
| Character control | Configure physics-based character control for first-person and third-person characters. | 
| Rigidbody physics | Apply physics-based behavior to GameObjects. | 
| Collision | Use colliders to configure collisions between GameObjects. | 
| Joints | Apply and configure joints that connect GameObjects and simulate physical forces for pivoting, movement, and restriction. | 
| Articulations | Configure complex systems of rigid bodies and joints. | 
| Ragdoll physics | Configure ragdoll physics for characters. | 
| Cloth | Simulate fabric movement for character clothing and other in-application textiles. | 
| Multi-scene physics | Manage different physics contexts in one project with multiple dedicated physics scenes. |
