Shader-属性定义

shader的属性类型总共有Int,Float,Color,Range,Vector,2D,Cube,3D总共8中类型，下面按类型来介绍:

Int属性定义的格式: 

name ("display name", Int) = number

Float属性定义的格式:

name ("display name", Float) = number

Range属性定义的格式:

name ("display name", Range (min, max)) = number

Color属性定义的格式:

name ("display name", Color) = (number,number,number,number)

Vector属性定义的格式:

name ("display name", Vector) = (number,number,number,number)

2D属性定义的格式:

name ("display name", 2D) = "defaulttexture" {}

Cube属性定义的格式:

name ("display name", Cube) = "defaulttexture" {}

3D属性定义的格式:

name ("display name", 3D) = "defaulttexture" {}

 下面我们来看一下完整的测试代码:

Shader "Hidden/TestVertex"
{
	Properties
	{
		_MainTex ("Texture", 2D) = "white" {}
		_TestInt("TestInt",Int)=1
		_TestFloat("TestFloat",Float)=2.0
		_TestVector4("TestVector4",Vector)=(0,0,0,0)
		_TestColor("TestColor",Color) = (1,0,0,1)
		_TestRange("TestRange",Range(0,100))=100
		_Test2D("Test2D",2D) = ""{}
		_TestCube("TestCube",Cube) = ""{}
		_Test3D("Test3D",3D) = ""{}
	}
	SubShader
	{
	}
}

 这样，我们定义的属性就显示在了unity面板上了。效果图:
