字体高亮：
获取UIlabel Effec属性调整
private void SetFont()
{
SetBrightnessFont(playerNum);
SetBrightnessFont(cardNum);
SetBrightnessFont(coinNum);
Invoke("NextFont", 0.3f);
}
private void SetBrightnessFont(UILabel uilabel) //设置字体高亮
{
uilabel.effectStyle = UILabel.Effect.Shadow;
uilabel.effectColor = new Color(255, 255, 255, 255);
}
private void RecoveryFont(UILabel uilabel) //字体高亮复原
{
uilabel.effectStyle = UILabel.Effect.Outline;
uilabel.effectColor = new Color(0,0,0, 255);
}
这样就可以实现字体高亮闪现的效果
图片高亮：
第一步修改Unlit - Premultiplied Colored
Shader "Unlit/Transparent Colored (Bright)"
{ Properties
{
_MainTex ("Base (RGB), Alpha (A)", 2D) =
"black" {}
_Bright("Brightness", Float) = 2
}
SubShader
{
LOD 100
Tags
{
"Queue" = "Transparent"
"IgnoreProjector" = "True"
"RenderType" = "Transparent"
}
Cull Off
Lighting Off
ZWrite Off
Fog { Mode Off }
Offset -1, -1
Blend SrcAlpha OneMinusSrcAlpha
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 : COLOR;
};
sampler2D _MainTex;
float4 _MainTex_ST;
float _Bright;
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) : COLOR
{
fixed4 col = tex2D(_MainTex, i.texcoord) * i.color;
col.rgb = _Bright * col.rgb;
return col;
}
ENDCG
}
}
SubShader
{
LOD 100
Tags
{
"Queue" = "Transparent"
"IgnoreProjector" = "True"
"RenderType" = "Transparent"
}
Pass
{
Cull Off
Lighting Off
ZWrite Off
Fog { Mode Off }
Offset -1, -1
ColorMask RGB
AlphaTest Greater .01
Blend SrcAlpha OneMinusSrcAlpha
ColorMaterial AmbientAndDiffuse
SetTexture [_MainTex]
{
Combine Texture * Primary
}
}
}
}
第二步：
将图片的Shader进行替换
如果是Sprite的话可以进行如下操作
1.创建新的Atlas
将Atlas Wooden Atlas 1的Material指定为Wooden Atlas 1
修改新的Material
增加亮度
修改Brightness即可（注意：修改后窗口可能不能立即显示效果，需要强制刷新对应的Panel）
应用
代码里面，用的时候将对应的sprite的atlas指定为新的atlas即可。
字体的灰化
和字体的高亮进行同样处理
图片的灰化
和图片的高亮唯一不同的只有shader代码了
shader代码
Shader "Unlit/Transparent Colored (Gray)"
{ Properties
{
_MainTex ("Base (RGB), Alpha (A)", 2D) =
"black" {}
}
SubShader
{
LOD 100
Tags
{
"Queue" = "Transparent"
"IgnoreProjector" = "True"
"RenderType" = "Transparent"
}
Cull Off
Lighting Off
ZWrite Off
Fog { Mode Off }
Offset -1, -1
Blend SrcAlpha OneMinusSrcAlpha
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 : COLOR;
};
sampler2D _MainTex;
float4 _MainTex_ST;
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) : COLOR
{
fixed4 col = tex2D(_MainTex, i.texcoord) * i.color;
col.rgb = dot(col.rgb, fixed3(.222,.707,.071));
return col;
}
ENDCG
}
}
SubShader
{
LOD 100
Tags
{
"Queue" = "Transparent"
"IgnoreProjector" = "True"
"RenderType" = "Transparent"
}
Pass
{
Cull Off
Lighting Off
ZWrite Off
Fog { Mode Off }
Offset -1, -1
ColorMask RGB
AlphaTest Greater .01
Blend SrcAlpha OneMinusSrcAlpha
ColorMaterial AmbientAndDiffuse
SetTexture [_MainTex]
{
Combine Texture * Primary
}
}
}
}

图片灰化的替代法
使用两套UITexture其中一套修改其ColorTint属性即可,这样做虽然快速有效，但消耗性能和内存。
