Unity用Shader实现波浪效果

实现的原理：让顶点的Y轴按正弦变化（余弦变化也可以），核心代码就一句 i.uv.y += (_Amplitude * sin(_AngularVelocity * i.uv.x + _Speed * _Time.y));

Shader "Custom/Wave" {Properties {_MainTex ("Albedo (RGB)", 2D) = "white" {}_Amplitude ("振幅(最大和最小的幅度)", Range(0, 1)) = 0.3             _AngularVelocity ("角速度(圈数)", Range(0, 50)) = 10             _Speed ("移动速度", Range(0, 30)) = 10  }SubShader {Tags { "LightMode" = "ForwardBase" }Pass {CGPROGRAM#pragma vertex vert#pragma fragment frag#include "UnityCG.cginc"#include "Lighting.cginc"sampler2D _MainTex;float4 _MainTex_ST;float _Amplitude;                 float _AngularVelocity;                 float _Speed;   struct v2f{float4 pos : SV_POSITION;float2 uv : TEXCOORD0; };  v2f vert(appdata_full  v){v2f o;o.pos = mul(UNITY_MATRIX_MVP, v.vertex);o.uv = TRANSFORM_TEX(v.texcoord, _MainTex);return o;}fixed4 frag(v2f i) : COLOR{i.uv.y += (_Amplitude * sin(_AngularVelocity * i.uv.x + _Speed * _Time.y));  float4 c = tex2D(_MainTex, i.uv);return c;}ENDCG}} FallBack "Diffuse"}
