这篇文章主要为大家详细介绍了Unity3D Shader实现镜子效果，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了Unity3D Shader实现镜子效果的具体代码，供大家参考，具体内容如下

Shader部分代码：

				?

									Shader "Custom/FanShe" {

									Properties{

									_MainTex("Albedo",2D) = "white"{}

									_MainTint("Diffuse Color",Color)=(1,1,1,1)

									_Cubemap("Cubemap",CUBE) = ""{}

									_ReflAmount("Reflection Amount",Range(0.1,1.0))=0.5

									}

									SubShader{

									Tags{"RenderType"="Opaque"}

									LOD 200

									CGPROGRAM

									#pragma surface surf Lambert

									#pragma target 3.0

									struct Input {

									float2 uv_MainTex;

									float3 worldRefl;

									};

									sampler2D _MainTex;

									samplerCUBE _Cubemap;

									fixed4 _MainTint;

									half _ReflAmount;

									void surf(Input IN, inout SurfaceOutput o)

									{

									fixed4 c = tex2D(_MainTex, IN.uv_MainTex)*_MainTint;

									o.Albedo = c.rgb;

									o.Emission = texCUBE(_Cubemap, IN.worldRefl)*_ReflAmount;

									o.Alpha = c.a;

									}

									ENDCG

									}

									FallBack "Diffuse"

									}

C#部分代码：

				?

									using System.Collections;

									using System.Collections.Generic;

									using UnityEngine;

									public class Shader_FanShe : MonoBehaviour {

									  public Cubemap cubeMap;

									  public Camera cam;

									  Material curmat;

									// Use this for initialization

									void Start () {

									    InvokeRepeating("change", 1, 0.1f);

									    curmat = gameObject.GetComponent<Renderer>().material;

									    if (curmat == null)

									    {

									      Debug.Log("cw");

									    }

									}

									// Update is called once per frame

									void Update () {

									}

									  void change()

									  {

									    cam.transform.rotation = Quaternion.identity;

									    cam.RenderToCubemap(cubeMap);

									    curmat.SetTexture("_Cubemap",cubeMap);

									  }

									}
