Unity Shader - vertex animation - Sin simple analog wave

• Create a shader, paste the following code under
• Create a material, setting Shader: Custom / Wave
• Baidu easily download a water texture mapping, set to the meterial of Tex, (can not set the default white all-white, not so intuitive)
• Create a Plane, the material to drag it (or MeshRender.materials [0] set material created above)

Code

Shader "Custom/Wave"
{
    Properties
    {
		_TintColor ("Tint Color", Color) = (1,1,1,1)
        _Tex ("Tex", 2D) = "white" {}
        _Speed ("Speed", Float) = 1.0
        _Amp ("Amp", Float) = 0.3
    }
    SubShader
    {
			Pass
			{
				Tags { "RenderType" = "Opaque" }

				CGPROGRAM

				#pragma vertex vert
				#pragma fragment frag

                #include "UnityCG.cginc"

                struct appdata
                {
                    float4 vertex : POSITION;
                    float2 uv : TEXCOORD0;
                };

                struct v2f
                {
                    float4 vertex : SV_POSITION;
                    float2 uv : TEXCOORD0;
                };

				fixed4 _TintColor;
                sampler2D _Tex;
                float4 _Tex_ST;
                float _Speed;
                float _Amp;

				v2f vert(appdata i)
				{
                    v2f o = (v2f)0;
                    o.vertex = UnityObjectToClipPos(i.vertex);
                    o.vertex.y += sin(_Time.y * _Speed + o.vertex.x + o.vertex.y) * _Amp;
                    o.uv = TRANSFORM_TEX(i.uv, _Tex);
                    return o;
				}

				fixed4 frag(v2f i) : SV_TARGET
				{
					return tex2D(_Tex, i.uv) * _TintColor;
				}

				ENDCG

    }
	FallBack "Diffuse"
}

Runtime

Under Wireframe, you can clearly see the animation vertices
