Bounds.IntersectRay 相交射线？


function IntersectRay (ray : Ray) : bool

Description描述

Does ray intersect this bounding box?

射线与这个边界框相交么？

using UnityEngine;using System.Collections;public class example : MonoBehaviour {public Ray ra = new Ray(Vector3.zero, Vector3.forward);void Update() {Debug.DrawRay(Vector3.zero, Vector3.forward * 999, Color.green);Bounds bounds = transform.collider.bounds;if (bounds.IntersectRay(ra))Debug.Log("Touched the ray");}}
// Creates a ray that points from the origin to the infinity among the z Axis.// And prints if the transform touched the ray.//沿着z轴，从原点到无限远，创建一条射线//并且如果变换碰到射线，打印消息var ra : Ray = new Ray (Vector3.zero, Vector3.forward);function Update () {// Color ra in the scene editor.//在场景编辑器，给射线一个颜色Debug.DrawRay (Vector3.zero, Vector3.forward * 999, Color.green);var bounds : Bounds = transform.collider.bounds;if (bounds.IntersectRay (ra))Debug.Log("Touched the ray");}

• function IntersectRay (ray : Ray, out distance : float) : bool

Description描述

Does ray intersect this bounding box?

射线与这个边界框相交么？

When IntersectRay returns true distance will be the distance to the ray's origin.

当IntersectRay返回真，距离将是到射线原点的距离。
