Scrolling Sprite

Hello,

I have created a simple uv scroller shader and it works perfectly on planes or other 3D meshes but not on 2D sprites.


Left: sprite. Right: 3D plane

Is there any way to make it works on sprite shader?
I've attached the project and here is the shader:

Code (CSharp):

1. Shader "Custom/ScrollingTexture" {
2.     Properties {
3.         _MainTex ("Base (RGB)", 2D) = "white" {}
4.         _TextureScroll ("Texture X Scroll", Range(0, 10)) = 5
5.     }
6.     SubShader {
7.         Tags { "RenderType"="Opaque" }
8.         LOD 200
9.        
10.         CGPROGRAM
11.         #pragma surface surf Lambert
12.  
13.         sampler2D _MainTex;
14.         float _TextureScroll;
15.  
16.         struct Input {
17.             float2 uv_MainTex;
18.             float3 uv_NormalTex;
19.             float3 vertColor;
20.         };
21.  
22.         void surf (Input IN, inout SurfaceOutput o) {
23.             float2 scrolledUV = IN.uv_MainTex;
24.             float scrollSpeed = _TextureScroll * _Time;
25.             scrolledUV += float2(scrollSpeed, scrollSpeed);
26.        
27.             half4 c = tex2D (_MainTex, scrolledUV);
28.             o.Albedo = c.rgb;
29.             o.Alpha = c.a;
30.         }
31.         ENDCG
32.     }
33.     FallBack "Diffuse"
34. }
35.  

Thanks.

 

Your sprite is set to clamp not repeat mode.

 

Hmm,

Is it possible to set the wrap mode for sprite on Unity5?

 

Or should I post this on 2D sub forum instead?

 

Not out of the box, no.

Oh that's true, sorry. 1. that's underwhelming... 2. you might be able to use an Image set to to Tiled type instead of a Sprite for your use case... 3. metas have a wrapmode setting for any texture but I haven't messed with this to see what happens if you change it on a sprite and do something Unity hides (might be fine? lot of dumb black boxing in other systems).

EDIT: You can set repeat mode on a sprite... Set texture import to advanced. Then sprite mode to whatever. Then you can set repeat mode.

 

Oh my, it works!
Thanks.
