EditorGUIUtility.SetIconForObject

Parameters

Description

Sets a custom icon to associate with a GameObject or MonoScript. The custom icon is displayed in the Scene view and the Inspector.

Custom icons for GameObjects are saved in the scene.

using UnityEngine;
using UnityEditor;

class Example
{
    [MenuItem("Examples/Set Custom Icon on GameObject")]
    public static void SetCustomIconOnGameObject()
    {
        var go = new GameObject();
        var icon = AssetDatabase.LoadAssetAtPath<Texture2D>("Assets/MyIcon.png");

        EditorGUIUtility.SetIconForObject(go, icon);
    }
}

Using this function, you can set custom icons directly on a MonoScript. However the next time the script is reimported, the change is lost.

using UnityEngine;
using UnityEditor;

class Example
{
    [MenuItem("Examples/Set Custom Icon on MonoScript")]
    public static void SetCustomIconOnMonoScript()
    {
        var monoImporter = AssetImporter.GetAtPath("Assets/MyMonoBehaviour.cs") as MonoImporter;
        var monoScript = monoImporter.GetScript();
        var icon = AssetDatabase.LoadAssetAtPath<Texture2D>("Assets/MyIcon.png");

        EditorGUIUtility.SetIconForObject(monoScript, icon);
    }
}

To make the custom icon persistent, call MonoImporter.SetIcon and AssetImporter.SaveAndReimport. If the script is in a managed plugin, call PluginImporter.SetIcon instead of MonoImporter.SetIcon.

When you set custom icons from a GUI, it is recommended that you defer reimport until the GUI is closed. If you reimport before the GUI is closed, the domain reload caused by recompiling the script could lead to a poor user experience.
