本shader主要實現顏色的明暗變化,通過COS()函式實現週期性的變化;
Shader "Unlit/ShanShuo" { Properties { _MainTex ("Texture", 2D) = "white" {} _MainColor("Color",Color)=(1,1,1,1) } SubShader { Tags { "RenderType"="Opaque" } LOD 100 Pass { 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);//基礎部分,不用多說 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);//功能的重點,通過COs()實現週期變化 // sample the texture fixed4 col = tex2D(_MainTex, i.uv)*b_color; return col; } ENDCG } } }
