Description

A static class for interacting with the Scene View icons and gizmos for types.

using System;
using UnityEditor;
using UnityEngine;

// An Editor Window that lets you edit the gizmo and icon properties for each selected component.
public class GizmoUtilityExample  : EditorWindow
{
    [MenuItem("Window/Gizmo Window")]
    static void Init() => GetWindow<GizmoUtilityExample>();

    Vector2 m_Scroll;

    void OnEnable()
    {
        autoRepaintOnSceneChange = true;
    }

        EditorGUI.BeginDisabled(!GizmoUtility.use3dIcons);
        GizmoUtility.iconSize = EditorGUILayout.Slider("3D Icon Size", GizmoUtility.iconSize, 0f, 1f);
        EditorGUI.EndDisabled();

        m_Scroll = EditorGUILayout.BeginScrollView(m_Scroll);

        foreach (var go in Selection.gameObjects)

            {
                // A component can have gizmos, an icon, both, or neither. A gizmo can also be disabled (the Editor
                // is collapsed in the Inspector).
                if (GizmoUtility.TryGetGizmoInfo(component.GetType(), out GizmoInfo info))
