帮我在unity中写一个shader脚本，使用后物体高光闪烁效果

好的，以下是一个简单的高光闪烁shader脚本：

Shader "Custom/Highlight" {
    Properties {
        _MainTex ("Texture", 2D) = "white" {}
        _Color ("Color", Color) = (1,1,1,1)
        _Shininess ("Shininess", Float) = 50
        _Gloss ("Gloss", Range(0, 1)) = 1
        _Frequency ("Frequency", Range(0, 5)) = 1.5
        _Speed ("Speed", Range(0, 5)) = 1.5
    }
    SubShader {
        Tags { "RenderType"="Opaque" }
        LOD 100

        CGPROGRAM
        #pragma surface surf Standard

        sampler2D _MainTex;
        float4 _Color;
        float _Shininess;
        float _Gloss;
        float _Frequency;
        float _Speed;

        struct Input {
            float2 uv_MainTex;
        };

        void surf (Input IN, inout SurfaceOutputStandard o) {
            float4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
            o.Albedo = c.rgb;
            o.Metallic = 0;
            o.Smoothness = pow(_Shininess/100, 2);
            o.Alpha = c.a;

            float t = _Time.y * _Speed;
            float f = sin(IN.uv_MainTex.x * _Frequency + t) * sin(IN.uv_MainTex.y * _Frequency + t);
            f = pow(f * _Gloss + 1 - _Gloss, 2);
            o.Emission = c.rgb * f;
        }
        ENDCG
    }
    FallBack "Diffuse"
}

将此脚本保存为highlight.shader，并将其附加到您希望使用高光闪烁效果的材质上。通过调整属性来改变高光的颜色、频率和速度。
