Collision.contacts 接触点列表

var contacts : ContactPoint[]

Description描述

The contact points generated by the physics engine.

接触点由物理引擎产生。

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.

每一个接触(contact)包含一个接触点、法线和两个碰撞的碰撞器(看ContactPoint)。在OnCollisionStayOnCollisionEnter里你确保contacts至少有一个元素。

using UnityEngine;

using System.Collections;



public class example : 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);

		}

	}

}
function OnCollisionStay(collision : Collision) {

	// Check if the collider we hit has a rigidbody

	// Then apply the force

	//检查如果碰撞的碰撞器有刚体,然后应用力

	for (var contact : ContactPoint in collision.contacts) {

		print(contact.thisCollider.name + " hit " + contact.otherCollider.name);

		// Visualize the contact point

		//可视化接触点

		Debug.DrawRay(contact.point, contact.normal, Color.white);

	}

}
using UnityEngine;

using System.Collections;



public class example : 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);

	}

}
// A grenade

//一个手榴弹

// - instantiates a explosion prefab when hitting a surface

// - then destroys itself

//当碰到表面时,实例化一个爆炸预设

var explosionPrefab : Transform;



function OnCollisionEnter(collision : Collision) {

	// Rotate the object so that the y-axis faces along the normal of the surface

	//旋转物体,y轴面沿着表面的法线。

	var contact = collision.contacts[0];

	var rot = Quaternion.FromToRotation(Vector3.up, contact.normal);

	var pos = contact.point;

	Instantiate(explosionPrefab, pos, rot);

	// Destroy the projectile

	//销毁手榴弹

	Destroy (gameObject);
