この collider/rigidbody は他の collider/rigidbody に触れたときに OnCollisionEnter は呼び出されます。
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 audio;
void Start() { audio = 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) audio.Play(); } }
OnCollisionEnter は関数の中にシンプルな yield 文を使用して、コルーチンにすることができます。
