Load All Prefabs In Directory
Helper script for loading all prefabs in a directory to a List
Not completely by me, found from:
With some modifications to return GameObjects instead of Components
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System.IO;
public static class PrefabLoader
//So, there's no "load all assets in directory" function in unity.
//I guess this is to avoid people using Prefabs as "data blobs".
//They'd rather you use ScriptableObjects... which is fine in some cases,
//but sometimes the thing you're blobbing is just a bunch of child transforms anyway,
//so it's huge buckets of sweat to reproduce the scene tools unity already has.
//The "AssetsDatabase.LoadAllAssetsAtPath" refers to /compound/ raw assets,
//like maya files. But it doesn't care about humble prefabs,
//which are more like compounds of assets, rather than raw assets.
//This function collates all the the behaviours you want in the directory you point it at. The path is relative to your Assets.
//i.e. "Assets/MyDirectory/"
//It returns the Prefab References, remember! Not instantiated scene objects!
//So it's only used for *editor-side* tools. Not run time.
//Quite useful in conjunction with "PrefabUtility".
public static List<GameObject> LoadAllPrefabsAt(string path)
if (path != "")
if (path.EndsWith("/"))
path = path.TrimEnd('/');
DirectoryInfo dirInfo = new DirectoryInfo(path);
FileInfo[] fileInf = dirInfo.GetFiles("*.prefab");
//loop through directory loading the game object and checking if it has the component you want
List<GameObject> prefabs = new List<GameObject>();
foreach (FileInfo fileInfo in fileInf)
string fullPath = fileInfo.FullName.Replace(@"\","/");
string assetPath = "Assets" + fullPath.Replace(Application.dataPath, "");
GameObject prefab = AssetDatabase.LoadAssetAtPath(assetPath, typeof(GameObject)) as GameObject;
if(prefab!= null)
return prefabs;
