CollisionDetectionMode.Discrete

Description

Continuous collision detection is off for this Rigidbody.

This is the default collision detection mode, and it is the fastest mode. Collisions for this collider will only be checked at the content's Time.fixedDeltaTime.

no example available in JavaScript

//This script allows you to switch collision detection mode at the press of the space key
//Attach this script to a GameObject
//Click the GameObject, go to its Inspector and click the Add Component Button. Then, go to Physics>Rigidbody.
