Why i don't see the shader i created by script ?

I'm using this wiki page:

http://wiki.unity3d.com/index.php?title=Shield

I have a spaceship object and i want the shield to be around the spaceship when the spaceship is in the middle of the shield.

In the editor i did: Assets > Create > Shader > Standrad Surface Shader
The double click on the created shader opened it in visual studio and added this code:

Code (csharp):

1.  
2. Shader "Custom/NewSurfaceShader" {
3.     Properties
4.     {
5.         _Color("_Color", Color) = (0.0,1.0,0.0,1.0)
6.         _Inside("_Inside", Range(0.0,2.0)) = 0.0
7.         _Rim("_Rim", Range(0.0,1.0)) = 1.2
8.         _Texture("_Texture", 2D) = "white" {}
9.     _Speed("_Speed", Range(0.5,5.0)) = 0.5
10.         _Tile("_Tile", Range(1.0,10.0)) = 5.0
11.         _Strength("_Strength", Range(0.0,5.0)) = 1.5
12.     }
13.  
14.         SubShader
15.     {
16.         Tags
17.     {
18.         "Queue" = "Transparent"
19.         "IgnoreProjector" = "True"
20.         "RenderType" = "Transparent"
21.  
22.     }
23.  
24.  
25.         Cull Back
26.         ZWrite On
27.         ZTest LEqual
28.

44.     struct EditorSurfaceOutput
45.     {
46.         half3 Albedo;

53.  
54.     inline half4 LightingBlinnPhongEditor_PrePass(EditorSurfaceOutput s, half4 light)
55.     {
56.         half3 spec = light.a * s.Gloss;
57.  
58.         half4 c;
59.  
60.         c.rgb = (s.Albedo * light.rgb + light.rgb * spec);
61.  
62.         c.a = s.Alpha + Luminance(spec);
63.  
64.         return c;
65.  
66.  
67.     }
68.  
69.     inline half4 LightingBlinnPhongEditor(EditorSurfaceOutput s, half3 lightDir, half3 viewDir, half atten)
70.     {
71.         viewDir = normalize(viewDir);
72.         half3 h = normalize(lightDir + viewDir);
73.  
74.         half diff = max(0, dot(s.Normal, lightDir));
75.  
76.         float nh = max(0, dot(s.Normal, h));
77.         float3 spec = pow(nh, s.Specular*128.0) * s.Gloss;
78.  
79.         half4 res;
80.         res.rgb = _LightColor0.rgb * (diff * atten * 2.0);
81.         res.w = spec * Luminance(_LightColor0.rgb);
82.  
83.         return LightingBlinnPhongEditor_PrePass(s, res);
84.     }
85.  
86.     struct Input
87.     {
88.         float4 screenPos;
89.         float3 viewDir;
90.         float2 uv_Texture;
91.     };
92.  
93.  
94.     void vert(inout appdata_full v, out Input o)
95.     {
96.         UNITY_INITIALIZE_OUTPUT(Input,o);
97.     }
98.  
99.  
100.     void surf(Input IN, inout EditorSurfaceOutput o)
101.     {
102.         o.Albedo = fixed3(0.0,0.0,0.0);
103.         o.Normal = fixed3(0.0,0.0,1.0);
104.         o.Emission = 0.0;
105.         o.Gloss = 0.0;

107.         o.Alpha = 1.0;
108.         float4 ScreenDepthDiff0 = LinearEyeDepth(tex2Dproj(_CameraDepthTexture, UNITY_PROJ_COORD(IN.screenPos)).r) - IN.screenPos.z;
109.         float4 Saturate0 = fixed4(0.3,0.3,0.3,1.0);//
110.         float4 Fresnel0_1_NoInput = fixed4(0,0,1,1);
111.         float dNorm = 1.0 - dot(normalize(float4(IN.viewDir, 1.0).xyz), normalize(Fresnel0_1_NoInput.xyz));
112.         float4 Fresnel0 = float4(dNorm,dNorm,dNorm,dNorm);
113.         float4 Step0 = step(Fresnel0,float4(1.0, 1.0, 1.0, 1.0));
114.         float4 Clamp0 = clamp(Step0,_Inside.xxxx,float4(1.0, 1.0, 1.0, 1.0));
115.         float4 Pow0 = pow(Fresnel0,(_Rim).xxxx);
116.         float4 Multiply5 = _Time * _Speed.xxxx;
117.         float4 UV_Pan0 = float4((IN.uv_Texture.xyxy).x,(IN.uv_Texture.xyxy).y + Multiply5.x,(IN.uv_Texture.xyxy).z,(IN.uv_Texture.xyxy).w);
118.         float4 Multiply1 = UV_Pan0 * _Tile.xxxx;
119.         float4 Tex2D0 = tex2D(_Texture,Multiply1.xy);
120.         float4 Multiply2 = Tex2D0 * _Strength.xxxx;
121.         float4 Multiply0 = Pow0 * Multiply2;
122.         float4 Multiply3 = Clamp0 * Multiply0;
123.         float4 Multiply4 = Saturate0 * Multiply3;
124.         o.Emission = Multiply3.xyz * _Color.rgb;
125.         o.Alpha = Multiply3.w * _Color.a;
126.  
127.     }
128.     ENDCG
129.     }
130.         Fallback "Diffuse"
131. }
132.  

Then same way i created a csharp script file and entered this code:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class ShieldUvAnimation : MonoBehaviour {
7.  
8.     public GameObject iShield;
9.     public float iSpeed;
10.  
11.     private Material mMaterial;
12.     private float mTime;
13.  
14.     // Use this for initialization
15.     void Start()
16.     {
17.         mMaterial = iShield.GetComponent<Renderer>().material;
18.  
19.         mTime = 0.0f;
20.     }
21.  
22.     // Update is called once per frame
23.     void Update()
24.     {
25.         mTime += Time.deltaTime * iSpeed;
26.  
27.         mMaterial.SetFloat("_Offset", Mathf.Repeat(mTime, 1.0f));
28.     }
29.  
30. }
31.  

Then for testing i created a empty GameObject attached the csharp script to it.
But now what should i do with the Shader ? I can't drag it anywhere to the empty GameObject.

And also what should i put in the inspector of the empty GameObject in the script in the filed iShield ?


Update

What i tried now is:

Ok i dragged the shader i created to a new material i created.
Then i changed in the script the variable

Code (csharp):

1. private Material mMaterial;

To be public

Code (csharp):

1. public Material mMaterial;

Then i dragged the new material to the empty gameobject in the inspector to the filed mMaterial.
And in the filed iShield i dragged there my spaceship object.

I'm running the game no errors but i don't see any shield.
