[REL] Collapse all GameObjects recursively in Hierarchy view

Collapses all GameObjects in Hierarchy view recursively, with a single keyboard shortcut or a menu item.
Drop the script in an Editor folder. Shortcut is Ctrl-Alt-Left on Windows, menu item is "Window/Collapse Hierarchy".

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEngine.SceneManagement;
4.  
5. public class HierarchyCollapser {
6.     [MenuItem("Window/Collapse Hierarchy %&LEFT")]
7.     public static void CollapseHierarchy() {
8.         EditorApplication.ExecuteMenuItem("Window/Hierarchy");
9.         var hierarchyWindow = EditorWindow.focusedWindow;
10.         var expandMethodInfo = hierarchyWindow.GetType().GetMethod("SetExpandedRecursive");
11.         foreach (GameObject root in SceneManager.GetActiveScene().GetRootGameObjects()) {
12.             expandMethodInfo.Invoke(hierarchyWindow, new object[] { root.GetInstanceID(), false });
13.         }
14.     }
15. }
16.  

This should outperform iterating all GameObjects and collapsing them individually. This code is available under the MIT License.

That's handy thanks alot

 

I like this. I am going to add 'No expand if item is disabled.'
