Unity 明暗闪烁shader

【Unity 明暗闪烁shader】本shader主要实现颜色的明暗变化,通过COS()函数实现周期性的变化;

Shader "Unlit/ShanShuo" { Properties { _MainTex ("Texture", 2D) = "white" {} _MainColor("Color",Color)=(1,1,1,1) } SubShader { Tags { "RenderType"="Opaque" } LOD 100Pass { CGPROGRAM #pragma vertex vert #pragma fragment frag#include "UnityCG.cginc"struct appdata { float4 vertex : POSITION; float2 uv : TEXCOORD0; }; struct v2f { float2 uv : TEXCOORD0; float4 vertex : SV_POSITION; }; sampler2D _MainTex; float4 _MainTex_ST; fixed4 _MainColor; v2f vert (appdata v) { v2f o; o.vertex = UnityObjectToClipPos(v.vertex); //基础部分,不用多说 o.uv = TRANSFORM_TEX(v.uv, _MainTex); return o; }fixed4 frag (v2f i) : SV_Target { fixed4 b_color =_MainColor*((cos( _Time.y*4)+3)/8.0); //功能的重点,通过COs()实现周期变化 // sample the texture fixed4 col = tex2D(_MainTex, i.uv)*b_color; return col; } ENDCG } } }
