Animated texture for projector?

I found this one in another Thread but it does not work in unity iphone.

Code (csharp):

1. var newTexture : Texture;
2.  
3. function Start ()
4. {
5.    SwapTexture (newTexture);
6. }
7.  
8. function SwapTexture (swap : Texture)
9. {
10.    var projector = GetComponent (Projector);
11.    projector.material.SetTexture ("_ShadowTex", swap);
12. }

Any idea how to make a animated projection on the iphone?

 

got it by changing a script from the unity reference:

Code (csharp):

1. #pragma strict
2.  
3. // Change renderer's texture each changeInterval
4. // seconds from the texture array defined in the inspector.
5. var textures : Texture[];
6. var changeInterval = 0.33;
7.  
8. function Update() {
9.    
10.     var proj : Projector = GetComponent (Projector);
11.  
12.    
13.     if( textures.length == 0 ) // nothing if no textures
14.         return;
15.  
16.     // we want this texture index now
17.     var index : int = Time.time / changeInterval;
18.     // take a modulo with size so that animation repeats
19.     index = index % textures.length;
20.     // assign it
21.     proj.material.mainTexture = textures[index];
22. }

 

VIC20, thats SUPER Expensive, doing a GetComponent every frame when the reference to the projector never changes.

Code (csharp):

1. #pragma strict
2.  
3. // Change renderer's texture each changeInterval
4. // seconds from the texture array defined in the inspector.
5. var textures : Texture[];
6. var changeInterval = 0.33;
7. var proj : Projector;  // you can drag the projector onto this in the editor, then get rid of the Start() function if you want.
8.  
9. function Start() {
10.      proj = GetComponent (Projector);
11. }
12.  
13. function Update() {
14.  
15.     if( textures.length == 0 ) // nothing if no textures
16.         return;
17.  
18.     // we want this texture index now
19.     var index : int = Time.time / changeInterval;
20.     // take a modulo with size so that animation repeats
21.     index = index % textures.length;
22.     // assign it
23.     proj.material.mainTexture = textures[index];
24. }

uups thank you!

 

How can I make this work on the projector shader?

 

Urgh I really need this to work too. I'm using the light projector at the minutes but its too dark, I need it to be additive not blend. -_-
