Collision 碰撞

描述碰撞

碰撞信息被传递给Collider.OnCollisionEnter, Collider.OnCollisionStay和Collider.OnCollisionExit这些事件。

示例：

Collision.contacts 接触点

物理引擎生成的碰撞点集。

    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);
            }
        }
    }

    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);
        }
    }

ContactPoint 接触点

描述碰撞发生位置的一个接触点。

碰撞点被存储在碰撞对象中。参见:Collision
