Unity的遮罩技术简述

遮罩技术是一个基本的技术方法,有很多很多中用法.你可以在Flash中经常看到遮罩的使用,它可以另一些视觉元素更加惊艳.当我看到Unity中没有包含任何几何体和图片的遮罩技术很不爽,不过,幸运的我找到了解决方案,就是"Depth Mask"着色器.

先看看着色器的代码,没错,非常短.  
  
Shader "Depth Mask" \{  
    SubShader\{  
        ColorMask 0  
        Pass \{\}  
    \}  
\}  
  
如果用了多维材质,你需要像下面这样写:  
  
Shader "Depth Mask Complex"  
\{  
    SubShader  
    \{  
        Tags \{"Queue" = "Background"\}  
        Blend SrcAlpha OneMinusSrcAlpha  
        Lighting Off  
        ZWrite On  
        ZTest Always  
        Pass  
        \{  
            Color(0,0,0,0)  
        \}  
    \}  
\}

如果你想更改任何一个物体材质的特性座遮罩(纹理,颜色等等)将是失败的,除非你用SetPass()去设置着色器,关于这个方法的文档在这( [http://unity3d.com/support/documentation/ScriptReference/Material.SetPass.html][http_unity3d.com_support_documentation_ScriptReference_Material.SetPass.html]).
