Bounds.IntersectRay 相交射线

转载自：http://game.ceeger.com/Script/Bounds/Bounds.IntersectRay.htmlfunction IntersectRay (ray : Ray) : bool Description描述Does ray intersect this bounding box?射线与这个边界框相交么？C#JavaScript

// 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, outdistance : 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。C#JavaScript

// Creates a ray that points from the origin to 10 units among the z Axis.
// And prints if the transform touched the ray.
//沿着z轴，从原点到10个单位之间，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);
var t : float = 10.0;

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 * 10, Color.green);
var bounds : Bounds = transform.collider.bounds;
if (bounds.IntersectRay (ra, t))
Debug.Log("Touched the ray");
