How to set reference with script?

[nguyentrong101094]

I have to write editor script that set the reference using a csv file.

var reorderedStages = new SmartReference.Runtime.SmartReference<GameObject>[stagePack.Stages.Count];

            foreach (var pair in mapping)
            {
                //...
                if (originalId >= 0 && originalId < stagePack.Stages.Count && newIndex >= 0 && newIndex < reorderedStages.Length)
                {
                    reorderedStages[newIndex] = AssetLoadWrapper.LoadStage(string.Format(AssetLoadWrapper.STAGE_PREFAB_NAME_FORMAT, originalId), null);
                }
            }

AssetLoadWrapper.LoadStage return a gameObject prefab.

setting reorderedStages's value this way is not allowed. So how do I set the value of SmartReference in code?

Hi,
At runtime this is indeed not supported because SmartReference<GameObject> will store the asset path and guid which can only get in editor. But if you are doing it only in editor, you can manually set these fields in SmartReference

public string guid;
public long fileID;
public string path;
public string type;

For now you can get these fields by:

AssetDatabase.TryGetGUIDAndLocalFileIdentifier(gameObject, out var guid, out long fileID);
AssetDatabase.GetAssetPath(gameObject);
type = typeof(GameObject).AssemblyQualifiedName

I may consider adding an editor helper function to do this in future, thanks for the feedback!
