About AssetDatabase.GetAssetPath can not find the right path

As saying on title, I use GetAssetPath API for finding the path of a texture..
Sometimes can get the right path, but sometimes not. I've searched long time and get nothing useful.
Here is my code:

Code (CSharp):

1.         var texAssets = new List<Texture2D>();
2.         var textures = Resources.FindObjectsOfTypeAll<Texture2D>();
3.         foreach (var texture2D in textures)
4.         {
5.             var path = AssetDatabase.GetAssetPath(texture2D);
6.             if (!string.IsNullOrEmpty(path))
7.             {
8.                 texAssets.Add(texture2D);
9.             }
10.         }

using this code, I can get the right texture asset list by sometimes...don't know the reason~

 

FindObjectsOfTypeAll returns only loaded objects, so I assume you're trying to find textures that were not loaded instead.

 

Since Unity 4.5 there is a new method which allows you to find assets in your project without actually loading them. Of course, you can then load them if you want:

Code (csharp):

1. foreach (string assetGuid in AssetDatabase.FindAssets("t:Texture2D")) {
2.     string assetPath = AssetDatabase.GUIDToAssetPath(assetGuid);
3.     var texture = AssetDatabase.LoadAssetAtPath(assetPath, typeof(Texture2D)) as Texture2D;
4.  
5.     // Do what you want with the texture...
6. }

I hope this helps

 

Thanks for replying,but Not as you say, this methods return all the texture including the assets, I got about thousands textures by using this method. the problem is GetAssetPath sometimes do not work properly

 

Thanks , I'll try this...From the API description, I think that's it...thanks again~~

 

Here's some helper functions, if you want: http://forum.unity3d.com/threads/loadallassetsatpath.21444/
