JavaScript => public var contacts: ContactPoint[];
C# => public ContactPoint[] contacts;

Description 描述

The contact points generated by the physics engine.

物理引擎生成的碰撞点集。

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.

每个接触包含接触点，正常的和两个碰撞体碰撞(请参考ContactPoint)。从内部的OnCollisionStay 或者OnCollisionEnter 你总是可以确定碰撞的最新元素。

JavaScript:

function OnCollisionStay(collision : Collision) {
		for (var contact : ContactPoint in collision.contacts) {
			print(contact.thisCollider.name + " hit " + contact.otherCollider.name);
			// Visualize the contact point
			Debug.DrawRay(contact.point, contact.normal, Color.white);
		}
	}

JavaScript:

#pragma strict
// A grenade
// - instantiates a explosion prefab when hitting a surface
// - then destroys itself
public var explosionPrefab: Transform;
function OnCollisionEnter(collision: Collision) {
	var contact: ContactPoint = collision.contacts[0];
	var rot: Quaternion = Quaternion.FromToRotation(Vector3.up, contact.normal);
	var pos: Vector3 = contact.point;
	Instantiate(explosionPrefab, pos, rot);
	Destroy(gameObject);
}

C#:

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);
        }
    }
}

C#:

	// 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);
    }
