unity3d shader 代码控制开关属性

直接上代码shader

Shader "ShaerTest" {Properties {    _Color("Tint",Color ) = (0.5,0.5,0.5,0.5)    _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}    [Enum(UnityEngine.Rendering.BlendMode)] _SrcBlend ("Src Blend Mode", Float) = 1  //声明外部控制开关    [Enum(UnityEngine.Rendering.BlendMode)] _DstBlend ("Dst Blend Mode", Float) = 1  //声明外部控制开关    [Enum(Off, 0, On, 1)] _ZWrite ("ZWrite", Float) = 0  //声明外部控制开关    [Enum(UnityEngine.Rendering.CompareFunction)] _ZTest ("ZTest", Float) = 0  //声明外部控制开关    [Enum(UnityEngine.Rendering.CullMode)] _Cull ("Cull Mode", Float) = 1  //声明外部控制开关}SubShader {    Tags {"Queue"="Geometry" "RenderType"="Opaque"}    LOD 200    Blend [_SrcBlend] [_DstBlend] //获取值应用    ZWrite [_ZWrite] //获取值应用    ZTest [_ZTest] //获取值应用    Cull [_Cull] //获取值应用    Pass {          CGPROGRAM            #pragma vertex vert            #pragma fragment frag            #include "UnityCG.cginc"            struct appdata_t {                float4 vertex : POSITION;                float2 texcoord : TEXCOORD0;                fixed4 color : COLOR;            };            struct v2f {                float4 vertex : SV_POSITION;                half2 texcoord : TEXCOORD0;                fixed4 color : TEXCOORD1;            };            sampler2D _MainTex;            float4 _MainTex_ST;            fixed4 _Color;            v2f vert (appdata_t v)            {                v2f o;                o.vertex = mul(UNITY_MATRIX_MVP, v.vertex);                o.texcoord = TRANSFORM_TEX(v.texcoord, _MainTex);                o.color = v.color;                return o;            }            fixed4 frag (v2f i) : SV_Target            {                fixed4 col = tex2D(_MainTex, i.texcoord)*_Color * i.color;                return col;            }        ENDCG    }}}   [Enum(UnityEngine.Rendering.CullMode)] _Cull ("Cull Mode", Float) = 1        [Enum(Off,0,On,1)] _ZWrite ("ZWrite", Float) = 1        [Enum(Less,0, Greater,1, LEqual,2, GEqual,3, Equal,4, NotEqual,5, Always,6)] _ZTest ("ZTest", Float) = 1        [Enum(UnityEngine.Rendering.BlendMode)] _SourceBlend ("Source Blend Mode", Float) = 2                [Enum(UnityEngine.Rendering.BlendMode)] _DestBlend ("Dest Blend Mode", Float) = 2

C#代码 下面举例一个 其他的你懂的

gameObject.GetComponent<MeshRenderer>().sharedMaterial.SetInt("_ZWrite", 1);
