Derive from this class to create an editor window.

Create your own custom editor window that can float free or be docked as a tab, just like the native windows in the Unity interface.

Editor windows are typically opened using a menu item.

class MyWindow extends EditorWindow {
    var myString = "Hello World";
    var groupEnabled = false;
    var myBool = true;
    var myFloat = 1.23;

// Add menu named "My Window" to the Window menu @MenuItem ("Window/My Window") static function Init () { // Get existing open window or if none, make a new one: var window = ScriptableObject.CreateInstance.<MyWindow>(); window.Show(); }

function OnGUI () { GUILayout.Label ("Base Settings", EditorStyles.boldLabel); myString = EditorGUILayout.TextField ("Text Field", myString);

groupEnabled = EditorGUILayout.BeginToggleGroup ("Optional Settings", groupEnabled); myBool = EditorGUILayout.Toggle ("Toggle", myBool); myFloat = EditorGUILayout.Slider ("Slider", myFloat, -3, 3); EditorGUILayout.EndToggleGroup (); } }
using UnityEngine;
using UnityEditor;
public class MyWindow : EditorWindow
    string myString = "Hello World";
    bool groupEnabled;
    bool myBool = true;
    float myFloat = 1.23f;

// Add menu named "My Window" to the Window menu [MenuItem("Window/My Window")] static void Init() { // Get existing open window or if none, make a new one: MyWindow window = (MyWindow)EditorWindow.GetWindow(typeof(MyWindow)); window.Show(); }

void OnGUI() { GUILayout.Label("Base Settings", EditorStyles.boldLabel); myString = EditorGUILayout.TextField("Text Field", myString);

groupEnabled = EditorGUILayout.BeginToggleGroup("Optional Settings", groupEnabled); myBool = EditorGUILayout.Toggle("Toggle", myBool); myFloat = EditorGUILayout.Slider("Slider", myFloat, -3, 3); EditorGUILayout.EndToggleGroup(); } }
