CollisionDetectionMode.Discrete

说明

此 Rigidbody 的连续碰撞检测处于关闭状态。

这是默认的碰撞检测模式，也是最快的模式。此碰撞器的碰撞只会按内容检查的 Time.fixedDeltaTime 进行。

//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.
