Refreshes the Hierarchy window.

Definition

  • Type: Method
  • Namespace: UnityEditor
  • Assembly: UnityEditor.CoreModule
public static void RepaintHierarchyWindow()

Remarks

Use EditorApplication.RepaintHierarchyWindow to refresh the Hierarchy window when changes to GameObjects, such as names, icons, or tags, are not automatically reflected in the Hierarchy window.
RepaintHierarchyWindow
can be useful when used with custom Editor tools or extensions that dynamically alter GameObject properties. 
RepaintHierarchyWindow
can negatively affect Editor performance, so avoid frequent calls in a performance-critical context.
This API is in the 
UnityEditor
namespace and can only be used in the Unity Editor. Typically, you combine it with EditorApplication.hierarchyChanged or custom events to ensure UI consistency.
Additional Resources: EditorApplication.HierarchyWindowItemByEntityIdCallback, EditorApplication.hierarchyWindowItemByEntityIdOnGUI.

Examples

using UnityEditor;using UnityEngine;[InitializeOnLoad]public class CustomHierarchyStyling{    static CustomHierarchyStyling()    {     // Register a callback to draw custom icons in the Hierarchy.     EditorApplication.hierarchyWindowItemByEntityIdOnGUI += OnHierarchyGUI;     // Repaint the Hierarchy window when the tag changes to reflect icon updates.     EditorApplication.hierarchyChanged += () => EditorApplication.RepaintHierarchyWindow();    }    static void OnHierarchyGUI(EntityId entityID, Rect selectionRect)    {        GameObject obj = EditorUtility.EntityIdToObject(entityID) as GameObject;        //Add a tag named "Special" to the GameObject to display the custom icon        if (obj != null && obj.CompareTag("Special"))        {             // Draw a custom icon on the left side of the GameObject in the Hierarchy            Rect iconRect = new Rect(selectionRect.x - 20, selectionRect.y, 18, 18);            GUI.Label(iconRect, EditorGUIUtility.IconContent("d_Favorite"));        }    }}
