UnityShader如何使用属性

Shader \"Custom/UsePropertiesShader\"{ Properties{

//声明⼀个Color 类型的属性

_Color(\"Color Tint\ }

SubShader{ Pass{

CGPROGRAM

#pragma vertex vert #pragma fragment frag

//在CG代码中，我们需要定义⼀个与属性名称和类型都匹配的变量 fixed4 _Color;

struct a2v{

float4 vertex:POSITION; float3 normal:NORMAL;

float4 texcoord:TEXCOORD0; };

struct v2f{

float4 pos:SV_POSITION; float3 color:COLOR0; };

v2f vert(a2v v){ v2f o;

o.pos=UnityObjectToClipPos(v.vertex); o.color=v.normal*0.5+fixed3(0.5,0.5,0.5); return o; }

fixed4 frag(v2f i):SV_Target{ fixed3 c=i.color; c*=_Color.rgb;

return fixed4(c,1.0); }

ENDCG } }
