Collision detection is the physics engine’s process for detecting when a physics body (Rigidbody or ArticulationBody) comes into contact with a collider. Unity provides different collision detection algorithms for different situations, so that you can choose the most efficient approach for each individual physics body (Rigidbody or Articulation Body) in your scene.

| Choose a collision detection mode | Choose the right collision detection mode for each collider in your project. |
| Layer-based collision detection | Use layers to define which GameObjects can collide with each other. |
| Discrete collision detectionA collision detection method that calculates and resolves collisions based on the pose of objects at the end of each physics simulation step. More info See in Glossary |
