how to Pass Sprite to SpriteRenderer in OnPostprocessSprites() Event?!

after importing sprites inside unity , i want to make a Prefab out Of them and assign them a SpriteRenderer and BoxCollider2D component , all automaticly.
every thing is good exept i cant pass the imported Sprite to the SpriteRenderer component any how.
i dont knoow what im missing here. any help will be appritiated.

Code (CSharp):

1.  void OnPostprocessSprites(Texture2D texture, Sprite[] sprites)
2.        {
3.          
4.         Sprite sp = sprites[0];
5.             TextureImporter importer = (TextureImporter)assetImporter;
6.             importer.textureType = TextureImporterType.Sprite;
7.  
8.             GameObject GO = new GameObject();
9.            GO.name = sp.name;
10.             GO.AddComponent<SpriteRenderer>().sprite = sp;// not works
11.             GO.AddComponent<SpriteRenderer>().sprite = (Sprite)Resources.Load(importer.assetPath);// not works
12.  
13.             GO.AddComponent<BoxCollider2D>();
14.  
15.             Object prefab = PrefabUtility.CreateEmptyPrefab(string.Format("Assets/Resources/X_Temp/{0}.prefab", GO.name));
16.            if (prefab != null)PrefabUtility.ReplacePrefab(GO, prefab, ReplacePrefabOptions.ConnectToPrefab);
17.  
18.         }
19.  

there is no Error or messages , it makes the prefab with BoxCollider And SpriteRendere Components But SpriteRenderer's Sprite Field Has No Sprite, and set to none.

how can i fix this?

 

Please add code formatting tags to make your code more readable.

Also, after this line:

Code (csharp):

1. Sprite sp = sprites[0];

Insert a line that says:

Code (csharp):

1. Debug.Log( "Sprite = " + sp.ToString());

And see if it prints the name of the sprite or not. That will identify if the problem is inside this block of code or external to it, in the code that sets up the array of sprites.

 

yes it returns the name of imported sprite.
and this :

Code (CSharp):

1. importer.assetPath

returns the imported path+name of sprite correctlly.

 

I will assume that the duplication of Line 10 and line 11 is intentional to show the two approaches you tried?
