Unity 2018 Shaders and Effects Cookbook

How to do it...

To create this animated effect, you can start by refitting the shader. Follow these steps:

1. Add the following properties:

_NoiseTex("Noise text", 2D) = "white" {}_Colour ("Colour", Color) = (1,1,1,1)_Period ("Period", Range(0,50)) = 1_Magnitude ("Magnitude", Range(0,0.5)) = 0.05_Scale ("Scale", Range(0,10)) = 1

2. Add their respective variables to the second pass of the shader:

sampler2D _NoiseTex;fixed4 _Colour;float _Period;float _Magnitude;float _Scale;

3. Define the following input and output structures for the vertex function:

struct vertInput {  float4 vertex : POSITION;  fixed4 color : COLOR;  float2 texcoord : TEXCOORD0;};struct vertOutput {  float4 vertex : POSITION;  fixed4 color : COLOR;  float2 texcoord : TEXCOORD0;
