建议用ps新建一个rbg为106,106,107的淡黑色图作为这个东东的材质，透明度为40%
Shader &Custom / newMirror & {
Properties {
&&&&_MainTex (&Base (RGB)&, 2D) = &white& {}
&&&&_ReflectionTex (&Reflection&, 2D) = &white& { TexGen ObjectLinear }
// two texture cards: full thing
Subshader {
&&&&Pass {
&&&&&&&&SetTexture[_MainTex] { combine texture }
&&&&&&&&SetTexture[_ReflectionTex] { matrix [_ProjMatrix] combine texture * previous }
// fallback: just main texture
Subshader {
&&&&Pass {
&&&&&&&&SetTexture [_MainTex] { combine texture }
、、、、、、、然后新建一个cs文件& 命名为newMirror.cs

unity 编辑器和插件制作（四.2）上次 我们讲述的是编辑器制作，怎么把图片加载到场景中，今天 我们就来讲述下，怎么 制作UIButton以及UIimage的互换。
废话不多说。进入正题。
首先我们要了解 unity的机制，button属性必须有的属性等。
首先 我们先说下 unity的机制：
unity中检测点击事件，使用NGUI的可能知道，NGUI使用的就是SendMessage的方式来进行事件的传递。没错，这也是 unity最为简便的方式，
（要注意一个问题哦，这个方式 如果 你要使用 大于 万次循环的话 会有延迟的哦,一般也不会同时发送万条事件的）。
我们知道了 事件的传送的方式，那么我们就开始制作这个规则，首先 要使用SendMessage的话我们要拿到gameobject的对象才能使用。
所以我们要想办法拿到点击的那个物体。怎么坐那，原理其实很简单，就是射线。我们都知道，unity的射线是用来探测使用的 正好，我们所有可以看到的物体都是存在camera下面，那么我们就可以使用，从camera上发射射线，来达到检测物体的作用，物体要有碰撞体哦。
先贴部分代码等这个章节完了我会贴完整的代码

这些是camera的部分，还有一点这个 我们没有贴我的适配方案 摄像机的适配方案，这里统配是的设计方案，因为这里我估计还要改下，发现这个摄像机适配方案，超出了unity的物理引擎的范围。不建议，不过可以参考。

camera的编辑器类

好下面我们来讲述下，button的一些东西，其实就很简单了。只是在编辑器方面可能会有些麻烦。
说白了 就是button就来处理 摄像机发来的东西。虽然很简单的一句话，但我们写得东西还是有很多的。
依然，button还是继承前面的view

这里有个 动画效果 我是自己使用的hotween整合的一些东西，如果你想用自己的可以自己去做。hotween插件 我就不用公布了，可以去官网进行下载，各大论坛也有下载资源。

下面就是button的编辑器方面了。ok，这里可能有点麻烦。不过还是可以解决的。
首先我们要获取脚本里面的方法怎么获取那。根据c#的MSDN的描述我们可以看到。就是以下方法，这就是 为什么 NGUI 只能找到public属性的方法。
using UnityE
using System.C
using System.R
public class GetPublic : MonoBehaviour {
static public
MethodInfo[] GetObjectMethods(string selectedObjClass){
if(selectedObjClass==null)
MethodInfo[] methodInfos=
if(System.Type.GetType(selectedObjClass)==null){
return methodI
methodInfos =
System.Type.GetType(selectedObjClass).GetMethods(BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly);
return methodI
这里就是button编辑器的一些属性的传递，和界面的修改哈。

我这里扩展了一些功能，像移动啊，什么的。。其实还可以加一些功能的 ，这里只是学习。有兴趣的可以自己加些东西。
