Unity Shader 21 Simple examples

Here is a simple shader code (the default code when creating a shader), which is analyzed in line with the code.

2. Properties {...}

2.1 Surface Shader Property type

　　　　Float Range: Range (min, max)
　　　　Defines a float property, represented as a slider from Min to Max in the inspector.
Name ("Display Name", Range (Min, max)) = number

　　　　Color: Color
　　　　Defines a color property.
Name ("Display Name", Color) = (number,number,number,number)

　　　　Texture: 2D
　　　　Defines a 2D texture property.
Name ("Display Name", 2D) = "name" {options}

　　　　Rectangle: Rect
　　　　Defines a rectangle (non power of 2) texture property.
Name ("Display Name", Rect) = "name" {options}

　　　　Cubemap: Cube
　　　　Defines a cubemap texture property.
Name ("Display Name", Cube) = "name" {options}

　　　　Float: Float
　　　　Defines a float property.
Name ("Display Name", Float) = number

　　　　Vector: Vector
　　　　Defines a four-component vector property.
Name ("Display Name", Vector) = (number,number,number,number)
