对静态和动态几何体开启推测连续碰撞检测
这是一种可以用于动态和运动学物体的碰撞检测模式。它通常比其他 CCD 模式更便宜。它还更好地处理角运动。但是,在某些情况下,高速物体仍然可能穿透其他几何体。
//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.

public class Example : MonoBehaviour { Rigidbody m_Rigidbody;
void Start() { //Attach this script to a GameObject. Ensure that it has a Rigidbody component. m_Rigidbody = GetComponent<Rigidbody>(); }
void Update() { //Press the space key to switch the collision detection mode if (Input.GetKeyDown(KeyCode.Space)) SwitchCollisionDetectionMode(); }
//Switch between the different Collision Detection Modes void SwitchCollisionDetectionMode() { switch (m_Rigidbody.collisionDetectionMode) { //If the current mode is continuous, switch it to continuous dynamic mode case CollisionDetectionMode.Continuous: m_Rigidbody.collisionDetectionMode = CollisionDetectionMode.ContinuousDynamic; break; //If the current mode is continuous dynamic, switch it to continuous speculative case CollisionDetectionMode.ContinuousDynamic: m_Rigidbody.collisionDetectionMode = CollisionDetectionMode.ContinuousSpeculative; break;
