Self Illumination in my shader

Hello everyone. I'm new here, and always try to make everything by my own, but shaders is my problem. Searching in internet, dont make any results. I make a custom shader, from few others. I make a 2D game without any light sources in scene, and my shader using diffuse, but I need effect like in self illum shaders. This is my code:

Code (csharp):

1.  Shader "Example/Slices" {
2.     Properties {
3.       _Color ("Color", Color) = (1.0, 1.0, 1.0, 1.0)
4.     }
5.    
6.     SubShader {
7.       Tags { "RenderType" = "Opaque" }
8.       Cull Off
9.       CGPROGRAM
10.       #pragma surface surf Lambert
11.       struct Input {
12.           float2 uv_MainTex;
13.           float3 worldPos;
14.       };
15.      
16.      fixed4 _Color;
17.      
18.       void surf (Input IN, inout SurfaceOutput o) {
19.           clip (frac((IN.worldPos.y+IN.worldPos.z*0.1) * 5) - 0.5);
20.           o.Albedo = _Color.rgb;
21.       }
22.       ENDCG
23.     }
24.     Fallback "Diffuse"
25.   }

P.S. sorry for my English. I'm from Ukraine.

 

You can download the shader source here: https://unity3d.com/unity/download/archive

In there you can check out how they did their illumination shader and apply it yourself. They're all surface shaders I think, so that shouldn't be a problem. Do note that surface shaders generally always apply a lighting function, but considering you have no lights in your scene, this shouldn't really matter.

 

Thank you. If you interested in result, check this out:

Code (csharp):

1.  Shader "Custom/Slices" {
2.     Properties {
3.       _Color ("Color", Color) = (1.0, 1.0, 1.0, 1.0)
4.       _Fade ("Alpha cutoff", Range(0,1)) = 1
5.     }
6.    
7.     SubShader {
8.       Tags { "RenderType" = "Opaque" }
9.       Cull Off
10.       CGPROGRAM
11.       #pragma surface surf Lambert
12.       struct Input {
13.           float2 uv_MainTex;
14.           float3 worldPos;
15.           float2 uv_Illum;
16.       };
17.      
18.      fixed4 _Color;
19.      half _Fade;
20.      
21.       void surf (Input IN, inout SurfaceOutput o) {
22.           clip (frac((IN.worldPos.y*+IN.worldPos.z*0.1) * 5) - 0.5);
23.           o.Albedo = _Color.rgb * (_Color.a - _Fade);
24.           o.Emission = _Color.rgb * 1;
25.       }
26.       ENDCG
27.     }
28.     Fallback "Self-Illumin/VertexLit"
29.   }
