Script Box - In-Engine Code Editor

Tired of context-switching to heavy, external IDEs just to tweak a single line of code or fix a minor bug?

Script Box is a lightweight, modern, text-based code editor built entirely within the Unity Editor using the native UI Toolkit architecture. It provides a frictionless workflow environment designed to let you edit, search, navigate, and protect your C# scripts without ever leaving your active project layout.

Key Features

• Roslyn-Powered Autocompletion: Code efficiently with intelligent, case-filtered code suggestions and autocomplete triggers (Ctrl+Space).
• Deep Code Navigation ("Go to Definition"): Jump straight to your symbol declarations using the F12 hotkey or right-click menu, complete with multi-file fallback searching across your Unity project files.
• Smart Find & Replace Suite: A powerful, contextual search (Ctrl+F / Ctrl+H) that pre-seeds your cursor text, highlights matches across line numbers dynamically, and supports safe multi-instance replacements.
• Automatic Version Backups: Every script save records an independent rollback snapshot. Instantly compare, manage, and toggle through historical versions using the integrated layout visualizer.
• Built-in Diagnostics Console: Track syntax and compilation diagnostics natively in real-time with an active error list panel that allows you to click an error and instantly navigate to the problematic line.
• Visual Customization: Ship with custom theme configurations.

Script Box isn't designed to replace your favorite full-scale external IDE—it's designed to save you hours of compounding compilation and software load delays. Whether you are hacking through an intense game jam or fine-tuning values during playtesting, Script Box keeps you focused on your code with zero external friction.
