Prefill list with AssetDatabase.LoadAssetAtPath

Hey guys,

I've been struggling to automatize some assets referencing in my project. It seemed to be going well until I tried to make a build.

Here's the main point : I have a list that I want to fill with prefabs references. When I drag and drop prefabs one by one, it all works great. I wanted to automatize this, call a method in the editor that would automatically find assets in the editor and fill up the list instead of dragging assets one by one. Here's how I do it :

 public void initList()
     {
         string[] foldersToSearch = new string[]{"Assets/Prefabs/Modules"};
 
         string[] modules = AssetDatabase.FindAssets("t:GameObject", foldersToSearch);
 
         List<string> lPaths = new List<string>();
 
         foreach (string guid in modules)
         {
             string sName = AssetDatabase.GUIDToAssetPath(guid);
             if (sName.Contains("Button") == false)
             {
                 lPaths.Add(sName);
             }
         }
 
         _lPrefabsUsed.Clear();
 
         foreach (string path in lPaths)
         {
             _lPrefabsUsed.Add(AssetDatabase.LoadAssetAtPath<GameObject>(path) as GameObject);
         }
     }

Of course I only call this from the editor but then I expect that the list _lPrefabsUsed would keep references to the prefabs so I can instantiate them at anytime during the game. But when I hit play the list empties. I guess AssetDatabase.LoadAssetAtPath is not the way to go or not enough to do what I want but I can't figure out how to do this.

Any ideas?

Thanks!
