How Do I Open Script Editor in Unity?

Published in Unity Editor 2 mins read

To open the script editor in Unity, you need to configure which external editor Unity uses for script editing. Here's how:

  1. Open Unity's Preferences: Navigate to Edit > Preferences (Windows) or Unity > Settings > Preferences (macOS) in the Unity Editor menu.

  2. Select External Tools: In the Preferences window, click on the "External Tools" tab.

  3. Choose Your Script Editor: Find the "External Script Editor" dropdown menu. This menu allows you to select your preferred code editor (e.g., Visual Studio, Visual Studio Code, Rider, or others).

  4. Open a Script: Once you've chosen your editor, you can open a script by double-clicking it in the Project window or by right-clicking on the script and selecting "Open" or "Open C# Project". This will launch the script in your selected external script editor.

Alternative Method:

Right-clicking on a .cs file within the Project Window provides options like:

  • Open: Opens the script using the configured External Script Editor.
  • Open C# Project: Opens the entire Unity project in your script editor, which is useful for navigating all scripts and project files.

Common Script Editors & Notes:

  • Visual Studio: A popular choice, especially on Windows. It integrates well with Unity and provides debugging features.
  • Visual Studio Code: A lightweight and versatile editor with excellent extension support. Requires the C# extension for optimal Unity development.
  • Rider: A paid IDE from JetBrains, built specifically for Unity development. It offers advanced features like code analysis and refactoring, similar to ReSharper.

Troubleshooting:

  • If your selected editor doesn't open the script: Ensure that the editor is properly installed on your system and that Unity recognizes it. Sometimes, restarting Unity or reinstalling the editor can resolve the issue.
  • If you have multiple versions of the same editor installed: Specify the correct version in the "External Script Editor Args" field (under External Tools) if necessary. Consult your editor's documentation for the correct command-line arguments.
