Hi there,
I’m using a cel-shaded style for my game through the Toon Lighted/Outline Shader and I need my enemies to fade out once killed.
Do any of you know how to add the alpha channel to a shader?
I know it’s been answered before but that was for the Toon Basic shader, and I’ve tried applying those concepts to the Lighted version, but Lighted seems to be a bit more complicated and I must be missing something.
Thanks,
Jordan
Here’s the Shader:
Shader "Toon/Lighted" {
Properties {
_Color ("Main Color", Color) = (0.5,0.5,0.5,1)
_MainTex ("Base (RGB)", 2D) = "white" {}
_Ramp ("Toon Ramp (RGB)", 2D) = "gray" {}
}
SubShader {
Tags {"Queue"="Transparent" "RenderType"="Transparent"}
Blend SrcAlpha OneMinusSrcAlpha
LOD 200
CGPROGRAM
#pragma surface surf ToonRamp
sampler2D _Ramp;
// custom lighting function that uses a texture ramp based
// on angle between light direction and normal
#pragma lighting ToonRamp exclude_path:prepass
inline half4 LightingToonRamp (SurfaceOutput s, half3 lightDir, half atten)
{
#ifndef USING_DIRECTIONAL_LIGHT
lightDir = normalize(lightDir);
#endif
half d = dot (s.Normal, lightDir)*0.5 + 0.5;
half3 ramp = tex2D (_Ramp, float2(d,d)).rgb;
half4 c;
c.rgb = s.Albedo * _LightColor0.rgb * ramp * (atten * 2);
c.a = 0;
return c;
}
sampler2D _MainTex;
float4 _Color;
struct Input {
float2 uv_MainTex : TEXCOORD0;
};
void surf (Input IN, inout SurfaceOutput o) {
half4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
o.Albedo = c.rgb;
o.Alpha = c.a;
}
ENDCG
}
Fallback "Diffuse"
}
And here’s the outlined version.
Shader "Toon/Lighted Outline" {
Properties {
_Color ("Main Color", Color) = (0.5,0.5,0.5,1)
_OutlineColor ("Outline Color", Color) = (0,0,0,1)
_Outline ("Outline width", Range (.002, 0.03)) = .005
_MainTex ("Base (RGB)", 2D) = "white" {}
_Ramp ("Toon Ramp (RGB)", 2D) = "gray" {}
}
SubShader {
Tags { "RenderType"="Opaque" }
UsePass "Toon/Basic/FORWARD"
UsePass "Toon/Basic Outline/OUTLINE"
}
Fallback "Toon/Lighted"
}
Currently, the object with the shader on is transparent, but it is always transparent and I have no control on it with the alpha channel. Any help, please?
