説明

物理エンジンにより生成された衝突情報

すべての衝突情報は衝突地点と法線、衝突した二つのコライダーを含みます ( ContactPoint を参照) OnCollisionStayOnCollisionEnter の中には 必ず contacts が最低一つ含まれます。

using UnityEngine;
using System.Collections;

public class ExampleClass : 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); } } }
// A grenade
// - instantiates a explosion prefab when hitting a surface
// - then destroys itself

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public Transform explosionPrefab; void OnCollisionEnter(Collision collision) { ContactPoint contact = collision.contacts[0]; Quaternion rot = Quaternion.FromToRotation(Vector3.up, contact.normal); Vector3 pos = contact.point; Instantiate(explosionPrefab, pos, rot); Destroy(gameObject); } }
