Gone Shroom’in!

Published 5/19/2013 by createdbyx in News

I'll be heading to High Level, Alberta May 26, 2013 to do some Morel picking for at least a few weeks. The last time I went Morel picking was about 6+ years ago so it will be fun to try it again.

Need to send simulated user input to the game window? Unity provides the EditorGUIUtility.QueueGameViewInputEvent method for doing just that. Using this method you could construct a utility that captures and plays back user input as your game is running which would be handy for debugging and unit testing purposes.

Below is a simple bit of code that will attempt to retrieve the asset path of the prefab stored on disk. The method will also try to walk up the prefab hierarchy if the prefab parameter appears to be a instance of the original. 

/// <summary>
/// Gets the source path to a prefab if any.
/// </summary>
/// <param name="prefab">The prefab reference to get the asset path for.</param>
/// <returns>Returns a asset path for a prefab.</returns>
/// <remarks>This method will attempt to find the source asset of the given <see cref="UnityEngine.Object"/> by 
/// walking up the parent prefab hierarchy.</remarks>
public static string GetSourcePrefab(UnityEngine.Object prefab)
    // if no prefab specified then return null
    if (prefab == null)
        return null;

    // attempt to get the path
    var path = AssetDatabase.GetAssetPath(prefab);

    // if no path returned it may be an instantiated prefab so try to get the parent prefab
    while (String.IsNullOrEmpty(path))
        // try parent prefab
        var parent = PrefabUtility.GetPrefabParent(prefab);
        // no parent so must be generated through code so just exit loop
        if (parent == null)

        // attempt to get path for 
        path = AssetDatabase.GetAssetPath(parent);

        // set prefab reference to parent for next loop
        prefab = parent;

    // return the path if any
    return path;
