MonoBehaviour.OnCollisionEnter(Collision)

切换到手册

参数

other 与该碰撞关联的碰撞数据。

描述

当该碰撞体/刚体已开始接触另一个刚体/碰撞体时,调用 OnCollisionEnter。

In contrast to OnTriggerEnter, OnCollisionEnter is passed the Collision class and not a Collider. The Collision class contains information about contact points, impact velocity etc. If you don't use collisionInfo in the function, leave out the collisionInfo parameter as this avoids unneccessary calculations. Notes: Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached. Collision events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { AudioSource audioSource;

void Start() { audioSource = GetComponent<AudioSource>(); }

void OnCollisionEnter(Collision collision) { foreach (ContactPoint contact in collision.contacts) { Debug.DrawRay(contact.point, contact.normal, Color.white); }

if (collision.relativeVelocity.magnitude > 2) audioSource.Play(); } }

OnCollisionEnter 可以作为协同程序使用 - 在函数中使用 yield 语句即可。
