How to realize the streamer effect of UGUI mask in unity

This article is about how to implement UGUI mask streamer effects in unity. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Here is the core shader:

Shader "UI/Unlit/Flowlight" {Properties {[PerRendererData] _ MainTex ("Sprite Texture", 2D) = "white" {} _ Color ("Tint", Color) = (1,1,1,1) [MaterialToggle] _ OffSet ("OffSet", float) = 0 [MaterialToggle] PixelSnap ("Pixel snap", float) = 0

/ * Flowlight * / _ FlowlightMaskTex ("Mask Texture", 2D) = "white" {} _ FlowlightTex ("Add Move Texture", 2D) = "white" {} _ FlowlightColor ("FlowlightColor", Color) = (0,0,0,1) _ Power ("Power", float) = 1 _ SpeedX ("SpeedX", float) = 1 _ SpeedY ("SpeedY", float) = 0 / *-* /

/ * UI * / _ StencilComp ("Stencil Comparison", Float) = 8 _ Stencil ("Stencil ID", Float) = 0 _ StencilOp ("Stencil Operation", Float) = 0 _ StencilWriteMask ("StencilWriteMask", Float) = 255StencilReadMask ("StencilReadMask", Float) = 255 / *-- * /}

SubShader {Tags {"Queue" = "Transparent"IgnoreProjector" = "True"RenderType" = "Transparent"PreviewType" = "Plane"CanUseSpriteAtlas" = "True"}
