I'm trying to create a Tiled Sprite, what am I doing wrong?

Since apparently Unity 2D still lacks tiled sprites, I'm tyring to create a class which takes a normal Sprite and tiles it using custom dimentions.

It doesn't crash, but doesn't yield results either: I just get an empty sprite apparently.

The transform position is correct (unaltered), I do use Apply, and the new width is multiple of the original one. Now I'm clueless about what could be the problem.

Here's the script, can anybody help?

Code (csharp):

1.  
2.     using UnityEngine;
3.     using System.Collections;
4.    
5.     public class TiledSprite : MonoBehaviour
6.     {
7.         public int width,height;
8.    
9.         private SpriteRenderer renderer;
10.         private Sprite originalSprite;
11.    
12.         void Awake ()
13.         {
14.             renderer=GetComponent<SpriteRenderer>();
15.             originalSprite=renderer.sprite;
16.    
17.             // crea il nuovo Sprite
18.    
19.             Texture2D target = new Texture2D(width,height);
20.             int ow = originalSprite.texture.width;
21.             int oh = originalSprite.texture.height;
22.    
23.             Color32[] pixOrig = originalSprite.texture.GetPixels32();
24.             Color32[] pixDest = new Color32[width*height];
25.    
26.             int osize=ow*oh,dsize=width*height;
27.             int cur=0;
28.             while (cur<dsize)
29.             {
30.                 for (int cur2=0; cur2<osize; cur2++)
31.                 {
32.                     pixDest[cur++]=pixOrig[cur2];
33.                 }
34.             }
35.    
36.             target.SetPixels32(pixDest);
37.             target.Apply();
38.    
39.             Sprite newSprite = Sprite.Create(target,new Rect(0,0,width,height),new Vector2(width/2,height/2));
40.             renderer.sprite=newSprite;
41.         }
42.     }
43.  

 

hmm do you need to do this at runtime ? because you can use the slice "grid" option in the sprite editor , once you set the sprite mode to multiple.

 

This is not what I'm trying to do.

I want to display a single sprite, tiled multiple times.
