    Hello, I want to make a script that opens an addressable prefab asset into the prefab editor by its address.

    Something using PrefabUtility.LoadPrefabContents I guess but with an address. Thanks !

    we don't have a lookup map for address to asset in the editor (only guid to asset entry, which includes address). That being said, you should be able to grab the AddressableAssetSettings object, loop the groups, then loop the entries in the group to find the one you want.

    Keep in mind address is not enforced to be unique. A user can name multiple things with the same address.

    It should be something like this, I didn't test the OpenPrefab() method

    Code (CSharp):
    1.     void OpenPrefab()
    2.     {
    3.         if(TryGetAssetGuid("YourAddress", out var guid))
    4.         {
    5.             var path = AssetDatabase.GUIDToAssetPath(guid);
    6.             var asset = PrefabUtility.LoadPrefabContents(path);
    7.         }
    8.     }
    9.  
    10.         public static bool TryGetAssetGuid(string address, out string guid)
    11.         {
    12.             var path = "Assets/AddressableAssetsData/AssetGroups/Default Local Group.asset";
    13.             var assetGroup = AssetDatabase.LoadAssetAtPath<AddressableAssetGroup>(path);
    14.             var entries = assetGroup.entries;
    15.          
    16.             foreach(var entry in entries)
    17.             {
    18.                 if(string.Equals(address, entry.address, StringComparison.Ordinal))
    19.                 {
    20.                     guid = entry.guid;
    21.                     return true;
    22.                 }
    23.             }
    24.  
    25.             guid = null;
    26.             return false;
    27.         }
    28.  
    29.
