What Is Editor Scripting in Unity?

Unity is a powerful game development engine that allows developers to create interactive and immersive experiences. While Unity provides a user-friendly interface for designing and building games, it also offers a feature called Editor Scripting that enables developers to customize and extend the Unity editor itself.

Why Use Editor Scripting?

Editor Scripting is incredibly useful for automating repetitive tasks, creating custom tools, and enhancing the workflow within Unity. With Editor Scripting, you can streamline your development process, improve productivity, and add new functionality to the Unity editor.

How Does Editor Scripting Work?

In Unity, the editor is built using the same APIs available to developers when creating games. This means that you can harness the power of C# scripting to modify the editor’s behavior and appearance.

To get started with Editor Scripting, you need to create a new C# script in your project’s Assets folder. Make sure to place it inside an “Editor” folder to ensure it only runs in the Unity editor environment.

Once you have created your script, you can begin implementing custom functionality by utilizing various UnityEditor classes and methods. These classes provide access to different aspects of the Unity editor such as menus, inspectors, windows, and more.

Custom Inspectors

A common use case for Editor Scripting is creating custom inspectors. By extending UnityEditor.Editor class, you can override the OnInspectorGUI() method to define how your custom inspector should look and behave.

using UnityEditor;
using UnityEngine;

public class MyComponentEditor : Editor
    public override void OnInspectorGUI()
        // Custom inspector code here

This allows you to add additional functionality, rearrange fields, create custom UI elements, and more. Custom inspectors can greatly improve the clarity and usability of your editor interface.

Editor Windows

Another powerful aspect of Editor Scripting is the ability to create custom editor windows. These windows can be used to display and manipulate data specific to your project.

public class MyWindow : EditorWindow
// Window code here

public class MyWindowEditor
[MenuItem(“Window/My Window”)]
public static void ShowWindow()
EditorWindow.GetWindow(typeof(MyWindow), false, “My Window”);

With custom editor windows, you can create tools for data visualization, batch processing, debugging, or any other task that requires a standalone interface within Unity.

Tips for Effective Editor Scripting

  • Keep it organized: Use proper folder structure and naming conventions to keep your editor scripts organized. This will make it easier for you and other developers to find and maintain the scripts.
  • Use comments: Comment your code extensively to explain its purpose and functionality.

    This will help you understand the code when revisiting it later or when sharing it with others.

  • Experiment: Don’t be afraid to experiment with different editor scripting techniques. Unity’s API documentation is a great resource to explore various functionalities and possibilities.
  • Reuse code: If you find yourself duplicating similar functionality across different scripts, consider creating reusable functions or base classes. This will save time and effort in the long run.


Editor Scripting in Unity is a powerful tool that empowers developers to extend and customize the Unity editor itself. Whether it’s automating repetitive tasks, creating custom tools, or enhancing the workflow, Editor Scripting can greatly improve your productivity and efficiency as a game developer.

By leveraging C# scripting and the UnityEditor API, you can create custom inspectors, editor windows, and much more. So dive into the world of Editor Scripting and unlock new possibilities in your Unity development journey!
