Collision.contacts 接触点列表


var contacts : ContactPoint[]

Description描述

The contact points generated by the physics engine.

接触点由物理引擎产生。

Every contact contains a contact point, normal and the two colliders that collided (see ContactPoint).  From inside OnCollisionStay or OnCollisionEnter you can  always be sure that contacts has at least one element.

每一个接触（contact）包含一个接触点、法线和两个碰撞的碰撞器（看ContactPoint）。在OnCollisionStay或OnCollisionEnter里你确保contacts至少有一个元素。

using UnityEngine;using System.Collections;public class example : MonoBehaviour {void OnCollisionStay(Collision collision) {foreach (ContactPoint contact in collision.contacts) {print(contact.thisCollider.name + " hit " + contact.otherCollider.name);Debug.DrawRay(contact.point, contact.normal, Color.white);}}}
function OnCollisionStay(collision : Collision) {// Check if the collider we hit has a rigidbody// Then apply the force//检查如果碰撞的碰撞器有刚体，然后应用力for (var contact : ContactPoint in collision.contacts) {print(contact.thisCollider.name + " hit " + contact.otherCollider.name);// Visualize the contact point//可视化接触点Debug.DrawRay(contact.point, contact.normal, Color.white);}}
