CollisionDetectionMode.ContinuousSpeculative

描述

对于静态和动态几何形状，连续推断碰撞检测已开启

这是一种可以在动态和运动对象上使用的碰撞检测模式。该模式的成本通常低于其他 CCD 模式。此外，还可以更好地处理角运动。但是，在某些情况下，高速对象仍可能穿过其他几何形状。

//This script allows you to switch collision detection mode at the press of the space key, and move your GameObject. It also outputs collisions that occur to the console.
//Attach this script to a GameObject and make sure it has a Rigidbody component
//If it doesn't have a Rigidbody component, click the GameObject, go to its Inspector and click the Add Component button. Then, go to Physics>Rigidbody.
//Create another GameObject. Make sure it has a Collider, so you can test collisions between them.
