[Unity3D] [NGUI] to select an icon (highlighted or ashing)

NGUIDiscussion group: 333417608

Demand

Click on the monster portrait, portrait. (restrictions: highlight value only)

Method

Copy the Unlit - Transparent Colored.shader, modify(Finally, a complete shader)

Shader "Unlit/Transparent Colored" 

Instead of

Shader "Unlit/Transparent Colored (Bright)"

2,

Properties
	{
		_MainTex ("Base (RGB), Alpha (A)", 2D) = "black" {}
	}

Instead of

Properties
	{
		_MainTex ("Base (RGB), Alpha (A)", 2D) = "black" {}
		_Bright("Brightness", Float) = 2
	}

3, 

sampler2D _MainTex;
float4 _MainTex_ST;

Instead of

sampler2D _MainTex;
float4 _MainTex_ST;
float _Bright;

4, 

fixed4 frag (v2f i) : COLOR
{
	fixed4 col = tex2D(_MainTex, i.texcoord) * i.color;
	return col;
}

Instead of

fixed4 frag (v2f i) : COLOR
{
	fixed4 col = tex2D(_MainTex, i.texcoord) * i.color;
	col.rgb = _Bright * col.rgb;
	return col;
}

5, Save the name for the Unlit - Transparent Colored (Bright).shader 

Create a new Atlas

ReplicationAtlas and Material, pictured above is Wooden Atlas 1 (two is respectively Atlas and Material)

Material Atlas Wooden Atlas 1Designated asWooden Atlas 1

Revise the new Material

Increasing the brightness

Can be modified Brightness (Note: the modified window may not immediately display effect, need to refresh force corresponding to the Panel)

Application

The code which, when using the corresponding sprite atlas specified for the new atlas.

Effect

On the left is the highlighted icon. On the right is the ashing.

With complete Shader
