Animating UV's?

Code (csharp):

1. Shader "TwoTex_Alpha_VertLit" {
2. Properties {
3.     _Color ("Main Color", Color) = (1,1,1,1)
4.     _SpecColor ("Spec Color", Color) = (1,1,1,0)
5.     _Emission ("Emmisive Color", Color) = (0,0,0,0)
6.     _Shininess ("Shininess", Range (0.1, 1)) = 0.7
7.     _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
8.     _SubTex ("Base (RGB)", 2D) = "white" {}
9. }
10.  
11. Category {
12.     ZWrite Off
13.     Alphatest Greater 0
14.     Tags {Queue=Transparent}
15.     Blend SrcAlpha OneMinusSrcAlpha
16.     ColorMask RGB
17.     SubShader {
18.         Material {
19.             Diffuse [_Color]
20.             Ambient [_Color]
21.             Shininess [_Shininess]
22.             Specular [_SpecColor]
23.             Emission [_Emission]   
24.         }
25.         Pass{
26.             Lighting On
27.             SeparateSpecular On
28.             SetTexture [_SubTex] {
29.                 Combine texture
30.             }
31.  
32.                 }
33.    
34.     Pass{
35.             Lighting On
36.             SeparateSpecular On
37.             SetTexture [_MainTex] {
38.                 Combine texture * primary DOUBLE, texture * primary
39.             }
40.  
41.         }
42.     }
43.    
44. }
45. }

If I wanted to animate the UV's for the bottom texture (_MainTex) so it would scroll in say, a sine wave, how would I do it? would the bottom texture repeat automatically if it scrolled the UV's past the edge?

 

Check out the flickering monitors in this example. I use a sine wave to scroll one of the textures in "interlaceRoller.js".
