摄像机和目标物体连接一个射线，然后射线碰到的物体的Transparent/Diffuse全部设为半透明

using System.Collections;using System.Collections.Generic;using UnityEngine;public class XrayCameral : MonoBehaviour {    public Transform tar;    public List<Renderer> listLastRend = new List<Renderer>();    // Use this for initialization    void Start () {    }    // Update is called once per frame    void Update () {        for (int i = 0; i < listLastRend.Count; i++)        {            TransparencySet(listLastRend[i], 1.0f);        }        Vector3 tarDir = (tar.position - transform.position).normalized;        Debug.DrawLine(tar.position, transform.position, Color.red);        float tarDis = Vector3.Distance(tar.position, transform.position);        RaycastHit[] listHitObj = Physics.RaycastAll(transform.position, tarDir, tarDis);        Debug.Log(listHitObj.Length);        for (int i = 0; i < listHitObj.Length; i++)        {            RaycastHit hit = listHitObj[i];            if (hit.transform == tar.transform)            {                continue;            }            Renderer renderer = hit.collider.GetComponent<Renderer>();            listLastRend.Clear();            if (renderer)            {                listLastRend.Add(renderer);                TransparencySet(renderer,0.3f);            }        }    }    void TransparencySet(Renderer renderer,float a)    {        renderer.material.shader = Shader.Find("Transparent/Diffuse");        renderer.material.color = new Color(renderer.material.color.r, renderer.material.color.g, renderer.material.color.b, a);    }}
