pathThe path where the prefab is saved.
goThe GameObject that you want to create a prefab from.


Creates a prefab from a game object hierarchy.

Use this to create a prefab from a GameObject in the hierarchy, and give it a path to save the prefab in.

//Create a folder (Right click in the Assets directory, click Create>New Folder) and name it “Editor” if one doesn’t exist already.
//Place this script in that folder

//This script creates a new menu and a new menu item in the Editor window // Use the new menu item to create a prefab at the given path. If a prefab already exists it asks if you want to replace it //Click on a GameObject in your Hierarchy, then go to Examples>Create Prefab to see it in action.

public class Example : EditorWindow { //Creates a new menu (Examples) with a menu item (Create Prefab) [MenuItem("Examples/Create Prefab")] static void CreatePrefab() { //Keep track of the currently selected GameObject(s) GameObject[] objectArray = Selection.gameObjects;

//Loop through every GameObject in the array above foreach (GameObject gameObject in objectArray) { //Set the path as within the Assets folder, and name it as the GameObject's name with the .prefab format string localPath = "Assets/" + + ".prefab";

//Check if the Prefab and/or name already exists at the path if (AssetDatabase.LoadAssetAtPath(localPath, typeof(GameObject))) { //Create dialog to ask if User is sure they want to overwrite existing prefab if (EditorUtility.DisplayDialog("Are you sure?", "The prefab already exists.
