Collider types

Colliders in Unity have different colliderAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info
See in Glossary types depending on whether they have an associated RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info
See in Glossary, and how that Rigidbody is configured. A Collider’s type defines how it interacts with other colliders, and how it responds to simulated physics forces.
