CollisionDetectionMode.Discrete

描述

对于该 Rigidbody，连续碰撞检测已关闭。

这是默认碰撞检测模式，也是最快的模式。对该碰撞体的碰撞将 仅在该内容的 Time.fixedDeltaTime 进行检查。

//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.
