描述

连续碰撞检测开启,以便与静态网格几何形状碰撞。

将检测碰撞是否在该 Rigidbody 的路径中存在任何静态网格几何形状,即使碰撞发生在 两个 FixedUpdate 步骤之间也是如此。静态网格几何形状是未附加 Rigidbody 的任何 MeshCollider。 这还可防止已设置为 ContinuousDynamic 模式的 Rigidbodies 穿过该 Rigidbody。

//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.

using UnityEngine; using UnityEngine.UI;

public class Example : MonoBehaviour { Rigidbody m_Rigidbody;

void Start() { m_Rigidbody = GetComponent<Rigidbody>(); }

public 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 discrete mode case CollisionDetectionMode.ContinuousDynamic: m_Rigidbody.collisionDetectionMode = CollisionDetectionMode.Discrete; break;

//If the current mode is discrete, switch it to continuous mode case CollisionDetectionMode.Discrete: m_Rigidbody.collisionDetectionMode = CollisionDetectionMode.Continuous; break; } } }
