public ContactPoint[] contacts ;

Descripción

Los puntos de contacto generados por el motor de físicas.

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.

using UnityEngine;

public class ExampleScript : MonoBehaviour { void OnCollisionStay(Collision collision) { foreach (ContactPoint contact in collision.contacts) { print(contact.thisCollider.name + " hit " + contact.otherCollider.name); // Visualize the contact point 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); } }
