Derive from this base class to create a custom inspector or editor for your custom object.

using UnityEngine;
using System.Collections;

// This is not an editor script. public class MyPlayer : MonoBehaviour { public int armor = 75; public int damage = 25; public GameObject gun;

void Update() { // Update logic here... } }

For example, use a custom editor to change the appearance of the script in the Inspector.

Puede adjuntar el Editor a un componente personalizado utilizando el atributo CustomEditor.

There are multiple ways to design custom Editors. If you want the Editor to support multi-object editing, you can use the CanEditMultipleObjects attribute. Instead of modifying script variables directly, it's advantageous to use the SerializedObject and SerializedProperty system to edit them, since this automatically handles multi-object editing, undo, and Prefab overrides. If this approach is used a user can select multiple assets in the hierarchy window and change the values for all of them at once.

You can either use UIElements to build your custom UI or you can use IMGUI. To create a custom inspector using UIElements, you have to override the Editor.CreateInspectorGUI on the Editor class. To create a custom inspector using IMGUI, you have to override the Editor.OnInspectorGUI on the Editor class. If you use UIElements and have Editor.CreateInspectorGUI overwritten, any existing IMGUI implementation using Editor.OnInspectorGUI on the same Editor will be ignored.

Here's an example of a custom inspector:

Custom editor in the Inspector.

using UnityEditor;
using UnityEditor.UIElements;
using UnityEngine;
using UnityEngine.UIElements;
public class MyPlayerEditor : Editor
    const string resourceFilename = "custom-editor-uie";
    public override VisualElement CreateInspectorGUI()
        VisualElement customInspector = new VisualElement();
        var visualTree = Resources.Load(resourceFilename) as VisualTreeAsset;
        customInspector.styleSheets.Add(Resources.Load($"{resourceFilename}-style") as StyleSheet);
        return customInspector;

The following example defines the layout of a custom inspector in uxml. The definition loads as a resource and the VisualTreeAsset.CloneTree method puts the hierarchy in a VisualElement object.

The InspectorWindow will instantiate an InspectorElement containing the custom inspector. The InspectorElement will call Bind on the custom inspector binding it to the MyPlayer object.

<UXML xmlns="UnityEngine.UIElements" xmlns:e="UnityEditor.UIElements">
    <VisualElement class="player-property">
        <VisualElement class="slider-row">
            <Label class="player-property-label" text="Damage"/>
            <VisualElement class="input-container">
                <SliderInt class="player-slider" name="damage-slider" high-value="100" direction="Horizontal" binding-path="damage"/>
                <e:IntegerField class="player-int-field" binding-path="damage"/>
        <e:ProgressBar class="player-property-progress-bar" name="damage-progress" binding-path="damage" title="Damage"/>

<VisualElement class="player-property"> <VisualElement class="slider-row"> <Label class="player-property-label" text="Armor"/> <VisualElement class="input-container"> <SliderInt class="player-slider" name="armor-slider" high-value="100" direction="Horizontal" binding-path="armor"/> <e:IntegerField class="player-int-field" binding-path="armor"/> </VisualElement> </VisualElement> <e:ProgressBar class="player-property-progress-bar" name="armor-progress" binding-path="armor" title="Armor"/> </VisualElement>

<e:PropertyField class="gun-field" binding-path="gun" label="Gun Object"/> </UXML>

UIElements automatically updates the UI when data changes and vice-versa. To bind data and automatically update data and UI, set values for the "binding-path" attributes.

Styling of the inspector is done in uss.

.slider-row {
    flex-direction: row;
    justify-content: space-between;
    margin-top: 4px;
.input-container {
    flex-direction: row;
    flex-grow: .6;
    margin-right: 4px;
.player-property {
    margin-bottom: 4px;
.player-property-label {
    margin-left: 16;
.player-slider {
    margin-right: 4px;
.player-property-progress-bar {
    margin-left: 16px;
    margin-right: 4px;
.player-int-field {
    min-width: 48px;
.gun-field {
    justify-content: space-between;
    margin-left: 16px;
    margin-right: 4px;
    margin-top: 6px;
    flex-grow: .6;

Here's an example of a custom inspector using IMGUI and multi-selection:

using UnityEditor;
using UnityEngine;
using System.Collections;

// Custom Editor using SerializedProperties. // Automatic handling of multi-object editing, undo, and Prefab overrides. [CustomEditor(typeof(MyPlayer))] [CanEditMultipleObjects] public class MyPlayerEditor : Editor { SerializedProperty damageProp; SerializedProperty armorProp; SerializedProperty gunProp;

void OnEnable() { // Setup the SerializedProperties. damageProp = serializedObject.FindProperty ("damage"); armorProp = serializedObject.FindProperty ("armor"); gunProp = serializedObject.FindProperty ("gun"); }

public override void OnInspectorGUI() { // Update the serializedProperty - always do this in the beginning of OnInspectorGUI. serializedObject.Update ();

// Show the custom GUI controls. EditorGUILayout.IntSlider (damageProp, 0, 100, new GUIContent ("Damage"));

// Only show the damage progress bar if all the objects have the same damage value: if (!damageProp.hasMultipleDifferentValues) ProgressBar (damageProp.intValue / 100.0f, "Damage");

EditorGUILayout.IntSlider (armorProp, 0, 100, new GUIContent ("Armor"));

// Only show the armor progress bar if all the objects have the same armor value: if (!armorProp.hasMultipleDifferentValues) ProgressBar (armorProp.intValue / 100.0f, "Armor");

EditorGUILayout.PropertyField (gunProp, new GUIContent ("Gun Object"));

// Apply changes to the serializedProperty - always do this in the end of OnInspectorGUI. serializedObject.ApplyModifiedProperties (); }

// Custom GUILayout progress bar. void ProgressBar (float value, string label) { // Get a rect for the progress bar using the same margins as a textfield: Rect rect = GUILayoutUtility.GetRect (18, 18, "TextField"); EditorGUI.ProgressBar (rect, value, label); EditorGUILayout.Space (); } }

If automatic handling of multi-object editing, undo, and Prefab overrides is not needed, the script variables can be modified directly by the editor without using the SerializedObject and SerializedProperty system, as in the IMGUI example below.

using UnityEditor;
using UnityEngine;
using System.Collections;

// Example script with properties. public class MyPlayerAlternative : MonoBehaviour { public int damage; public int armor; public GameObject gun;

// ...other code... }

// Custom Editor the "old" way by modifying the script variables directly. // No handling of multi-object editing, undo, and Prefab overrides! [CustomEditor (typeof(MyPlayerAlternative))] public class MyPlayerEditorAlternative : Editor {

public override void OnInspectorGUI() { MyPlayerAlternative mp = (MyPlayerAlternative)target;

mp.damage = EditorGUILayout.IntSlider ("Damage", mp.damage, 0, 100); ProgressBar (mp.damage / 100.0f, "Damage");

mp.armor = EditorGUILayout.IntSlider ("Armor", mp.armor, 0, 100); ProgressBar (mp.armor / 100.0f, "Armor");

bool allowSceneObjects = !EditorUtility.IsPersistent (target); mp.gun = (GameObject)EditorGUILayout.ObjectField ("Gun Object", mp.gun, typeof(GameObject), allowSceneObjects); }

// Custom GUILayout progress bar. void ProgressBar (float value, string label) { // Get a rect for the progress bar using the same margins as a textfield: Rect rect = GUILayoutUtility.GetRect (18, 18, "TextField"); EditorGUI.ProgressBar (rect, value, label); EditorGUILayout.Space (); } }
